The Twin Tunnels Trail is a section of the ODOT Historic Columbia River Highway State Trail - US30 - that was restored as a pedestrian and bike trail in 2000.
The 4.5 mile segment between Hood River and Moiser, Oregon offers spectacular scenery as it parallels I-84. It's one of the finest bike trails in the US.
The monolith and poppies photographed here are near the midsection of the trail and were shot in late afternoon light.
Rumor is, an alum of Art Center was among the first in the area to buy an Audi R8 . For some reason or other, he lent it to Art Center for a few days, so the transportation design students (and the rest of the school, frankly) could gawk and awe.
It's a truly spell-binding piece of design. Incredibly curvaceous, well balanced, and boasting a bold carbon "stripe" along the midsection. I like it.
I'll take two.
Sheep (pl.: sheep) or domestic sheep (Ovis aries) are a domesticated, ruminant mammal typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juː/ yoo), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonwealth countries, ovine meat is called lamb when from younger animals and mutton when from older ones; in the United States, meat from both older and younger animals is usually called lamb. Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science.
Sheep husbandry is practised throughout the majority of the inhabited world, and has been fundamental to many civilizations. In the modern era, Australia, New Zealand, the southern and central South American nations, and the British Isles are most closely associated with sheep production.
There is a large lexicon of unique terms for sheep husbandry which vary considerably by region and dialect. Use of the word sheep began in Middle English as a derivation of the Old English word scēap. A group of sheep is called a flock. Many other specific terms for the various life stages of sheep exist, generally related to lambing, shearing, and age.
Being a key animal in the history of farming, sheep have a deeply entrenched place in human culture, and are represented in much modern language and symbolism. As livestock, sheep are most often associated with pastoral, Arcadian imagery. Sheep figure in many mythologies—such as the Golden Fleece—and major religions, especially the Abrahamic traditions. In both ancient and modern religious ritual, sheep are used as sacrificial animals.
History
Main article: History of the domestic sheep
The exact line of descent from wild ancestors to domestic sheep is unclear. The most common hypothesis states that Ovis aries is descended from the Asiatic (O. gmelini) species of mouflon; the European mouflon (Ovis aries musimon) is a direct descendant of this population. Sheep were among the first animals to be domesticated by humankind (although the domestication of dogs probably took place 10 to 20 thousand years earlier); the domestication date is estimated to fall between 11,000 and 9000 B.C in Mesopotamia and possibly around 7000 BC in Mehrgarh in the Indus Valley. The rearing of sheep for secondary products, and the resulting breed development, began in either southwest Asia or western Europe. Initially, sheep were kept solely for meat, milk and skins. Archaeological evidence from statuary found at sites in Iran suggests that selection for woolly sheep may have begun around 6000 BC, and the earliest woven wool garments have been dated to two to three thousand years later.
Sheep husbandry spread quickly in Europe. Excavations show that in about 6000 BC, during the Neolithic period of prehistory, the Castelnovien people, living around Châteauneuf-les-Martigues near present-day Marseille in the south of France, were among the first in Europe to keep domestic sheep. Practically from its inception, ancient Greek civilization relied on sheep as primary livestock, and were even said to name individual animals. Ancient Romans kept sheep on a wide scale, and were an important agent in the spread of sheep raising. Pliny the Elder, in his Natural History (Naturalis Historia), speaks at length about sheep and wool. European colonists spread the practice to the New World from 1493 onwards.
Characteristics
Domestic sheep are relatively small ruminants, usually with a crimped hair called wool and often with horns forming a lateral spiral. They differ from their wild relatives and ancestors in several respects, having become uniquely neotenic as a result of selective breeding by humans. A few primitive breeds of sheep retain some of the characteristics of their wild cousins, such as short tails. Depending on breed, domestic sheep may have no horns at all (i.e. polled), or horns in both sexes, or in males only. Most horned breeds have a single pair, but a few breeds may have several.
Sheep in Turkmenistan
Another trait unique to domestic sheep as compared to wild ovines is their wide variation in color. Wild sheep are largely variations of brown hues, and variation within species is extremely limited. Colors of domestic sheep range from pure white to dark chocolate brown, and even spotted or piebald. Sheep keepers also sometimes artificially paint "smit marks" onto their sheep in any pattern or color for identification. Selection for easily dyeable white fleeces began early in sheep domestication, and as white wool is a dominant trait it spread quickly. However, colored sheep do appear in many modern breeds, and may even appear as a recessive trait in white flocks. While white wool is desirable for large commercial markets, there is a niche market for colored fleeces, mostly for handspinning. The nature of the fleece varies widely among the breeds, from dense and highly crimped, to long and hairlike. There is variation of wool type and quality even among members of the same flock, so wool classing is a step in the commercial processing of the fibre.
Suffolks are a medium wool, black-faced breed of meat sheep that make up 60% of the sheep population in the U.S.
Depending on breed, sheep show a range of heights and weights. Their rate of growth and mature weight is a heritable trait that is often selected for in breeding. Ewes typically weigh between 45 and 100 kilograms (100 and 220 lb), and rams between 45 and 160 kilograms (100 and 350 lb). When all deciduous teeth have erupted, the sheep has 20 teeth. Mature sheep have 32 teeth. As with other ruminants, the front teeth in the lower jaw bite against a hard, toothless pad in the upper jaw. These are used to pick off vegetation, then the rear teeth grind it before it is swallowed. There are eight lower front teeth in ruminants, but there is some disagreement as to whether these are eight incisors, or six incisors and two incisor-shaped canines. This means that the dental formula for sheep is either
0.0.3.3
4.0.3.3
or
0.0.3.3
3.1.3.3
There is a large diastema between the incisors and the molars.
In the first few years of life one can calculate the age of sheep from their front teeth, as a pair of milk teeth is replaced by larger adult teeth each year, the full set of eight adult front teeth being complete at about four years of age. The front teeth are then gradually lost as sheep age, making it harder for them to feed and hindering the health and productivity of the animal. For this reason, domestic sheep on normal pasture begin to slowly decline from four years on, and the life expectancy of a sheep is 10 to 12 years, though some sheep may live as long as 20 years.
Skull
Sheep have good hearing, and are sensitive to noise when being handled. Sheep have horizontal slit-shaped pupils, with excellent peripheral vision; with visual fields of about 270° to 320°, sheep can see behind themselves without turning their heads. Many breeds have only short hair on the face, and some have facial wool (if any) confined to the poll and or the area of the mandibular angle; the wide angles of peripheral vision apply to these breeds. A few breeds tend to have considerable wool on the face; for some individuals of these breeds, peripheral vision may be greatly reduced by "wool blindness", unless recently shorn about the face. Sheep have poor depth perception; shadows and dips in the ground may cause sheep to baulk. In general, sheep have a tendency to move out of the dark and into well-lit areas, and prefer to move uphill when disturbed. Sheep also have an excellent sense of smell, and, like all species of their genus, have scent glands just in front of the eyes, and interdigitally on the feet. The purpose of these glands is uncertain, but those on the face may be used in breeding behaviors. The foot glands might also be related to reproduction, but alternative functions, such as secretion of a waste product or a scent marker to help lost sheep find their flock, have also been proposed.
Comparison with goats
Sheep and goats are closely related: both are in the subfamily Caprinae. However, they are separate species, so hybrids rarely occur and are always infertile. A hybrid of a ewe and a buck (a male goat) is called a sheep-goat hybrid, known as geep. Visual differences between sheep and goats include the beard of goats and divided upper lip of sheep. Sheep tails also hang down, even when short or docked, while the short tails of goats are held upwards. Also, sheep breeds are often naturally polled (either in both sexes or just in the female), while naturally polled goats are rare (though many are polled artificially). Males of the two species differ in that buck goats acquire a unique and strong odor during the rut, whereas rams do not.
Breeds
The domestic sheep is a multi-purpose animal, and the more than 200 breeds now in existence were created to serve these diverse purposes. Some sources give a count of a thousand or more breeds, but these numbers cannot be verified, according to some sources. However, several hundred breeds of sheep have been identified by the Food and Agriculture Organization of the UN (FAO), with the estimated number varying somewhat from time to time: e.g. 863 breeds as of 1993, 1314 breeds as of 1995 and 1229 breeds as of 2006. (These numbers exclude extinct breeds, which are also tallied by the FAO.) For the purpose of such tallies, the FAO definition of a breed is "either a subspecific group of domestic livestock with definable and identifiable external characteristics that enable it to be separated by visual appraisal from other similarly defined groups within the same species or a group for which geographical and/or cultural separation from phenotypically similar groups has led to acceptance of its separate identity." Almost all sheep are classified as being best suited to furnishing a certain product: wool, meat, milk, hides, or a combination in a dual-purpose breed. Other features used when classifying sheep include face color (generally white or black), tail length, presence or lack of horns, and the topography for which the breed has been developed. This last point is especially stressed in the UK, where breeds are described as either upland (hill or mountain) or lowland breeds. A sheep may also be of a fat-tailed type, which is a dual-purpose sheep common in Africa and Asia with larger deposits of fat within and around its tail.
Breeds are often categorized by the type of their wool. Fine wool breeds are those that have wool of great crimp and density, which are preferred for textiles. Most of these were derived from Merino sheep, and the breed continues to dominate the world sheep industry. Downs breeds have wool between the extremes, and are typically fast-growing meat and ram breeds with dark faces. Some major medium wool breeds, such as the Corriedale, are dual-purpose crosses of long and fine-wooled breeds and were created for high-production commercial flocks. Long wool breeds are the largest of sheep, with long wool and a slow rate of growth. Long wool sheep are most valued for crossbreeding to improve the attributes of other sheep types. For example: the American Columbia breed was developed by crossing Lincoln rams (a long wool breed) with fine-wooled Rambouillet ewes.
Coarse or carpet wool sheep are those with a medium to long length wool of characteristic coarseness. Breeds traditionally used for carpet wool show great variability, but the chief requirement is a wool that will not break down under heavy use (as would that of the finer breeds). As the demand for carpet-quality wool declines, some breeders of this type of sheep are attempting to use a few of these traditional breeds for alternative purposes. Others have always been primarily meat-class sheep.
A minor class of sheep are the dairy breeds. Dual-purpose breeds that may primarily be meat or wool sheep are often used secondarily as milking animals, but there are a few breeds that are predominantly used for milking. These sheep produce a higher quantity of milk and have slightly longer lactation curves. In the quality of their milk, the fat and protein content percentages of dairy sheep vary from non-dairy breeds, but lactose content does not.
A last group of sheep breeds is that of fur or hair sheep, which do not grow wool at all. Hair sheep are similar to the early domesticated sheep kept before woolly breeds were developed, and are raised for meat and pelts. Some modern breeds of hair sheep, such as the Dorper, result from crosses between wool and hair breeds. For meat and hide producers, hair sheep are cheaper to keep, as they do not need shearing. Hair sheep are also more resistant to parasites and hot weather.
With the modern rise of corporate agribusiness and the decline of localized family farms, many breeds of sheep are in danger of extinction. The Rare Breeds Survival Trust of the UK lists 22 native breeds as having only 3,000 registered animals (each), and The Livestock Conservancy lists 14 as either "critical" or "threatened". Preferences for breeds with uniform characteristics and fast growth have pushed heritage (or heirloom) breeds to the margins of the sheep industry. Those that remain are maintained through the efforts of conservation organizations, breed registries, and individual farmers dedicated to their preservation.
Diet
Sheep are herbivorous mammals. Most breeds prefer to graze on grass and other short roughage, avoiding the taller woody parts of plants that goats readily consume. Both sheep and goats use their lips and tongues to select parts of the plant that are easier to digest or higher in nutrition. Sheep, however, graze well in monoculture pastures where most goats fare poorly.
Ruminant system of a sheep
Like all ruminants, sheep have a complex digestive system composed of four chambers, allowing them to break down cellulose from stems, leaves, and seed hulls into simpler carbohydrates. When sheep graze, vegetation is chewed into a mass called a bolus, which is then passed into the rumen, via the reticulum. The rumen is a 19- to 38-liter (5 to 10 gallon) organ in which feed is fermented. The fermenting organisms include bacteria, fungi, and protozoa. (Other important rumen organisms include some archaea, which produce methane from carbon dioxide.) The bolus is periodically regurgitated back to the mouth as cud for additional chewing and salivation. After fermentation in the rumen, feed passes into the reticulum and the omasum; special feeds such as grains may bypass the rumen altogether. After the first three chambers, food moves into the abomasum for final digestion before processing by the intestines. The abomasum is the only one of the four chambers analogous to the human stomach, and is sometimes called the "true stomach".
Other than forage, the other staple feed for sheep is hay, often during the winter months. The ability to thrive solely on pasture (even without hay) varies with breed, but all sheep can survive on this diet. Also included in some sheep's diets are minerals, either in a trace mix or in licks. Feed provided to sheep must be specially formulated, as most cattle, poultry, pig, and even some goat feeds contain levels of copper that are lethal to sheep. The same danger applies to mineral supplements such as salt licks.
Grazing behavior
Sheep follow a diurnal pattern of activity, feeding from dawn to dusk, stopping sporadically to rest and chew their cud. Ideal pasture for sheep is not lawnlike grass, but an array of grasses, legumes and forbs. Types of land where sheep are raised vary widely, from pastures that are seeded and improved intentionally to rough, native lands. Common plants toxic to sheep are present in most of the world, and include (but are not limited to) cherry, some oaks and acorns, tomato, yew, rhubarb, potato, and rhododendron.
Effects on pasture
Sheep are largely grazing herbivores, unlike browsing animals such as goats and deer that prefer taller foliage. With a much narrower face, sheep crop plants very close to the ground and can overgraze a pasture much faster than cattle. For this reason, many shepherds use managed intensive rotational grazing, where a flock is rotated through multiple pastures, giving plants time to recover. Paradoxically, sheep can both cause and solve the spread of invasive plant species. By disturbing the natural state of pasture, sheep and other livestock can pave the way for invasive plants. However, sheep also prefer to eat invasives such as cheatgrass, leafy spurge, kudzu and spotted knapweed over native species such as sagebrush, making grazing sheep effective for conservation grazing. Research conducted in Imperial County, California compared lamb grazing with herbicides for weed control in seedling alfalfa fields. Three trials demonstrated that grazing lambs were just as effective as herbicides in controlling winter weeds. Entomologists also compared grazing lambs to insecticides for insect control in winter alfalfa. In this trial, lambs provided insect control as effectively as insecticides.
Behavior
Sheep are flock animals and strongly gregarious; much sheep behavior can be understood on the basis of these tendencies. The dominance hierarchy of sheep and their natural inclination to follow a leader to new pastures were the pivotal factors in sheep being one of the first domesticated livestock species. Furthermore, in contrast to the red deer and gazelle (two other ungulates of primary importance to meat production in prehistoric times), sheep do not defend territories although they do form home ranges. All sheep have a tendency to congregate close to other members of a flock, although this behavior varies with breed, and sheep can become stressed when separated from their flock members. During flocking, sheep have a strong tendency to follow, and a leader may simply be the first individual to move. Relationships in flocks tend to be closest among related sheep: in mixed-breed flocks, subgroups of the same breed tend to form, and a ewe and her direct descendants often move as a unit within large flocks. Sheep can become hefted to one particular local pasture (heft) so they do not roam freely in unfenced landscapes. Lambs learn the heft from ewes and if whole flocks are culled it must be retaught to the replacement animals.
Flock behaviour in sheep is generally only exhibited in groups of four or more sheep; fewer sheep may not react as expected when alone or with few other sheep. Being a prey species, the primary defense mechanism of sheep is to flee from danger when their flight zone is entered. Cornered sheep may charge and butt, or threaten by hoof stamping and adopting an aggressive posture. This is particularly true for ewes with newborn lambs.
In regions where sheep have no natural predators, none of the native breeds of sheep exhibit a strong flocking behavior.
Herding
Farmers exploit flocking behavior to keep sheep together on unfenced pastures such as hill farming, and to move them more easily. For this purpose shepherds may use herding dogs in this effort, with a highly bred herding ability. Sheep are food-oriented, and association of humans with regular feeding often results in sheep soliciting people for food. Those who are moving sheep may exploit this behavior by leading sheep with buckets of feed.
Dominance hierarchy
Sheep establish a dominance hierarchy through fighting, threats and competitiveness. Dominant animals are inclined to be more aggressive with other sheep, and usually feed first at troughs. Primarily among rams, horn size is a factor in the flock hierarchy. Rams with different size horns may be less inclined to fight to establish the dominance order, while rams with similarly sized horns are more so. Merinos have an almost linear hierarchy whereas there is a less rigid structure in Border Leicesters when a competitive feeding situation arises.
In sheep, position in a moving flock is highly correlated with social dominance, but there is no definitive study to show consistent voluntary leadership by an individual sheep.
Intelligence and learning ability
Sheep are frequently thought of as unintelligent animals. Their flocking behavior and quickness to flee and panic can make shepherding a difficult endeavor for the uninitiated. Despite these perceptions, a University of Illinois monograph on sheep reported their intelligence to be just below that of pigs and on par with that of cattle. Sheep can recognize individual human and ovine faces and remember them for years; they can remember 50 other different sheep faces for over two years; they can recognize and are attracted to individual sheep and humans by their faces, as they possess similar specialized neural systems in the temporal and frontal lobes of their brains to humans and have a greater involvement of the right brain hemisphere. In addition to long-term facial recognition of individuals, sheep can also differentiate emotional states through facial characteristics.[68][69] If worked with patiently, sheep may learn their names, and many sheep are trained to be led by halter for showing and other purposes. Sheep have also responded well to clicker training. Sheep have been used as pack animals; Tibetan nomads distribute baggage equally throughout a flock as it is herded between living sites.
It has been reported that some sheep have apparently shown problem-solving abilities; a flock in West Yorkshire, England allegedly found a way to get over cattle grids by rolling on their backs, although documentation of this has relied on anecdotal accounts.
Vocalisations
Sounds made by domestic sheep include bleats, grunts, rumbles and snorts. Bleating ("baaing") is used mostly for contact communication, especially between dam and lambs, but also at times between other flock members. The bleats of individual sheep are distinctive, enabling the ewe and her lambs to recognize each other's vocalizations. Vocal communication between lambs and their dam declines to a very low level within several weeks after parturition. A variety of bleats may be heard, depending on sheep age and circumstances. Apart from contact communication, bleating may signal distress, frustration or impatience; however, sheep are usually silent when in pain. Isolation commonly prompts bleating by sheep. Pregnant ewes may grunt when in labor. Rumbling sounds are made by the ram during courting; somewhat similar rumbling sounds may be made by the ewe, especially when with her neonate lambs. A snort (explosive exhalation through the nostrils) may signal aggression or a warning, and is often elicited from startled sheep.
Lamb
In sheep breeds lacking facial wool, the visual field is wide. In 10 sheep (Cambridge, Lleyn and Welsh Mountain breeds, which lack facial wool), the visual field ranged from 298° to 325°, averaging 313.1°, with binocular overlap ranging from 44.5° to 74°, averaging 61.7°. In some breeds, unshorn facial wool can limit the visual field; in some individuals, this may be enough to cause "wool blindness". In 60 Merinos, visual fields ranged from 219.1° to 303.0°, averaging 269.9°, and the binocular field ranged from 8.9° to 77.7°, averaging 47.5°; 36% of the measurements were limited by wool, although photographs of the experiments indicate that only limited facial wool regrowth had occurred since shearing. In addition to facial wool (in some breeds), visual field limitations can include ears and (in some breeds) horns, so the visual field can be extended by tilting the head. Sheep eyes exhibit very low hyperopia and little astigmatism. Such visual characteristics are likely to produce a well-focused retinal image of objects in both the middle and long distance. Because sheep eyes have no accommodation, one might expect the image of very near objects to be blurred, but a rather clear near image could be provided by the tapetum and large retinal image of the sheep's eye, and adequate close vision may occur at muzzle length. Good depth perception, inferred from the sheep's sure-footedness, was confirmed in "visual cliff" experiments; behavioral responses indicating depth perception are seen in lambs at one day old. Sheep are thought to have colour vision, and can distinguish between a variety of colours: black, red, brown, green, yellow and white. Sight is a vital part of sheep communication, and when grazing, they maintain visual contact with each other. Each sheep lifts its head upwards to check the position of other sheep in the flock. This constant monitoring is probably what keeps the sheep in a flock as they move along grazing. Sheep become stressed when isolated; this stress is reduced if they are provided with a mirror, indicating that the sight of other sheep reduces stress.
Taste is the most important sense in sheep, establishing forage preferences, with sweet and sour plants being preferred and bitter plants being more commonly rejected. Touch and sight are also important in relation to specific plant characteristics, such as succulence and growth form.
The ram uses his vomeronasal organ (sometimes called the Jacobson's organ) to sense the pheromones of ewes and detect when they are in estrus. The ewe uses her vomeronasal organ for early recognition of her neonate lamb.
Reproduction
Sheep follow a similar reproductive strategy to other herd animals. A group of ewes is generally mated by a single ram, who has either been chosen by a breeder or (in feral populations) has established dominance through physical contest with other rams. Most sheep are seasonal breeders, although some are able to breed year-round. Ewes generally reach sexual maturity at six to eight months old, and rams generally at four to six months. However, there are exceptions. For example, Finnsheep ewe lambs may reach puberty as early as 3 to 4 months, and Merino ewes sometimes reach puberty at 18 to 20 months. Ewes have estrus cycles about every 17 days, during which they emit a scent and indicate readiness through physical displays towards rams.
In feral sheep, rams may fight during the rut to determine which individuals may mate with ewes. Rams, especially unfamiliar ones, will also fight outside the breeding period to establish dominance; rams can kill one another if allowed to mix freely. During the rut, even usually friendly rams may become aggressive towards humans due to increases in their hormone levels.
After mating, sheep have a gestation period of about five months, and normal labor takes one to three hours. Although some breeds regularly throw larger litters of lambs, most produce single or twin lambs. During or soon after labor, ewes and lambs may be confined to small lambing jugs, small pens designed to aid both careful observation of ewes and to cement the bond between them and their lambs.
A lamb's first steps
Ovine obstetrics can be problematic. By selectively breeding ewes that produce multiple offspring with higher birth weights for generations, sheep producers have inadvertently caused some domestic sheep to have difficulty lambing; balancing ease of lambing with high productivity is one of the dilemmas of sheep breeding. In the case of any such problems, those present at lambing may assist the ewe by extracting or repositioning lambs. After the birth, ewes ideally break the amniotic sac (if it is not broken during labor), and begin licking clean the lamb. Most lambs will begin standing within an hour of birth. In normal situations, lambs nurse after standing, receiving vital colostrum milk. Lambs that either fail to nurse or are rejected by the ewe require help to survive, such as bottle-feeding or fostering by another ewe.
Most lambs begin life being born outdoors. After lambs are several weeks old, lamb marking (ear tagging, docking, mulesing, and castrating) is carried out. Vaccinations are usually carried out at this point as well. Ear tags with numbers are attached, or ear marks are applied, for ease of later identification of sheep. Docking and castration are commonly done after 24 hours (to avoid interference with maternal bonding and consumption of colostrum) and are often done not later than one week after birth, to minimize pain, stress, recovery time and complications. The first course of vaccinations (commonly anti-clostridial) is commonly given at an age of about 10 to 12 weeks; i.e. when the concentration of maternal antibodies passively acquired via colostrum is expected to have fallen low enough to permit development of active immunity. Ewes are often revaccinated annually about 3 weeks before lambing, to provide high antibody concentrations in colostrum during the first several hours after lambing. Ram lambs that will either be slaughtered or separated from ewes before sexual maturity are not usually castrated. Objections to all these procedures have been raised by animal rights groups, but farmers defend them by saying they save money, and inflict only temporary pain.
Homosexuality
Sheep are the only species of mammal except for humans which exhibits exclusive homosexual behavior. About 10% of rams refuse to mate with ewes but readily mate with other rams, and thirty percent of all rams demonstrate at least some homosexual behavior. Additionally, a small number of females that were accompanied by a male fetus in utero (i.e. as fraternal twins) are freemartins (female animals that are behaviorally masculine and lack functioning ovaries).
Health
Sheep may fall victim to poisons, infectious diseases, and physical injuries. As a prey species, a sheep's system is adapted to hide the obvious signs of illness, to prevent being targeted by predators. However, some signs of ill health are obvious, with sick sheep eating little, vocalizing excessively, and being generally listless. Throughout history, much of the money and labor of sheep husbandry has aimed to prevent sheep ailments. Historically, shepherds often created remedies by experimentation on the farm. In some developed countries, including the United States, sheep lack the economic importance for drug companies to perform expensive clinical trials required to approve more than a relatively limited number of drugs for ovine use. However, extra-label drug use in sheep production is permitted in many jurisdictions, subject to certain restrictions. In the US, for example, regulations governing extra-label drug use in animals are found in 21 CFR (Code of Federal Regulations) Part 530. In the 20th and 21st centuries, a minority of sheep owners have turned to alternative treatments such as homeopathy, herbalism and even traditional Chinese medicine to treat sheep veterinary problems. Despite some favorable anecdotal evidence, the effectiveness of alternative veterinary medicine has been met with skepticism in scientific journals. The need for traditional anti-parasite drugs and antibiotics is widespread, and is the main impediment to certified organic farming with sheep.
Many breeders take a variety of preventive measures to ward off problems. The first is to ensure all sheep are healthy when purchased. Many buyers avoid outlets known to be clearing houses for animals culled from healthy flocks as either sick or simply inferior. This can also mean maintaining a closed flock, and quarantining new sheep for a month. Two fundamental preventive programs are maintaining good nutrition and reducing stress in the sheep. Restraint, isolation, loud noises, novel situations, pain, heat, extreme cold, fatigue and other stressors can lead to secretion of cortisol, a stress hormone, in amounts that may indicate welfare problems. Excessive stress can compromise the immune system. "Shipping fever" (pneumonic mannheimiosis, formerly called pasteurellosis) is a disease of particular concern, that can occur as a result of stress, notably during transport and (or) handling. Pain, fear and several other stressors can cause secretion of epinephrine (adrenaline). Considerable epinephrine secretion in the final days before slaughter can adversely affect meat quality (by causing glycogenolysis, removing the substrate for normal post-slaughter acidification of meat) and result in meat becoming more susceptible to colonization by spoilage bacteria. Because of such issues, low-stress handling is essential in sheep management. Avoiding poisoning is also important; common poisons are pesticide sprays, inorganic fertilizer, motor oil, as well as radiator coolant containing ethylene glycol.
Common forms of preventive medication for sheep are vaccinations and treatments for parasites. Both external and internal parasites are the most prevalent malady in sheep, and are either fatal, or reduce the productivity of flocks. Worms are the most common internal parasites. They are ingested during grazing, incubate within the sheep, and are expelled through the digestive system (beginning the cycle again). Oral anti-parasitic medicines, known as drenches, are given to a flock to treat worms, sometimes after worm eggs in the feces has been counted to assess infestation levels. Afterwards, sheep may be moved to a new pasture to avoid ingesting the same parasites. External sheep parasites include: lice (for different parts of the body), sheep keds, nose bots, sheep itch mites, and maggots. Keds are blood-sucking parasites that cause general malnutrition and decreased productivity, but are not fatal. Maggots are those of the bot fly and the blow-fly, commonly Lucilia sericata or its relative L. cuprina. Fly maggots cause the extremely destructive condition of flystrike. Flies lay their eggs in wounds or wet, manure-soiled wool; when the maggots hatch they burrow into a sheep's flesh, eventually causing death if untreated. In addition to other treatments, crutching (shearing wool from a sheep's rump) is a common preventive method. Some countries allow mulesing, a practice that involves stripping away the skin on the rump to prevent fly-strike, normally performed when the sheep is a lamb. Nose bots are fly larvae that inhabit a sheep's sinuses, causing breathing difficulties and discomfort. Common signs are a discharge from the nasal passage, sneezing, and frantic movement such as head shaking. External parasites may be controlled through the use of backliners, sprays or immersive sheep dips.
A wide array of bacterial and viral diseases affect sheep. Diseases of the hoof, such as foot rot and foot scald may occur, and are treated with footbaths and other remedies. Foot rot is present in over 97% of flocks in the UK. These painful conditions cause lameness and hinder feeding. Ovine Johne's disease is a wasting disease that affects young sheep. Bluetongue disease is an insect-borne illness causing fever and inflammation of the mucous membranes. Ovine rinderpest (or peste des petits ruminants) is a highly contagious and often fatal viral disease affecting sheep and goats. Sheep may also be affected by primary or secondary photosensitization. Tetanus can also afflict sheep through wounds from shearing, docking, castration, or vaccination. The organism also can be introduced into the reproductive tract by unsanitary humans who assist ewes during lambing.
A few sheep conditions are transmissible to humans. Orf (also known as scabby mouth, contagious ecthyma or soremouth) is a skin disease leaving lesions that is transmitted through skin-to-skin contact. Cutaneous anthrax is also called woolsorter's disease, as the spores can be transmitted in unwashed wool. More seriously, the organisms that can cause spontaneous enzootic abortion in sheep are easily transmitted to pregnant women. Also of concern are the prion disease scrapie and the virus that causes foot-and-mouth disease (FMD), as both can devastate flocks. The latter poses a slight risk to humans. During the 2001 FMD pandemic in the UK, hundreds of sheep were culled and some rare British breeds were at risk of extinction due to this.
Of the 600,300 sheep lost to the US economy in 2004, 37.3% were lost to predators, while 26.5% were lost to some form of disease. Poisoning accounted for 1.7% of non-productive deaths.
Predators

Other than parasites and disease, predation is a threat to sheep and the profitability of sheep raising. Sheep have little ability to defend themselves, compared with other species kept as livestock. Even if sheep survive an attack, they may die from their injuries or simply from panic. However, the impact of predation varies dramatically with region. In Africa, Australia, the Americas, and parts of Europe and Asia predators are a serious problem. In the United States, for instance, over one third of sheep deaths in 2004 were caused by predation. In contrast, other nations are virtually devoid of sheep predators, particularly islands known for extensive sheep husbandry. Worldwide, canids—including the domestic dog—are responsible for most sheep deaths. Other animals that occasionally prey on sheep include: felines, bears, birds of prey, ravens and feral hogs.
Sheep producers have used a wide variety of measures to combat predation. Pre-modern shepherds used their own presence, livestock guardian dogs, and protective structures such as barns and fencing. Fencing (both regular and electric), penning sheep at night and lambing indoors all continue to be widely used. More modern shepherds used guns, traps, and poisons to kill predators, causing significant decreases in predator populations. In the wake of the environmental and conservation movements, the use of these methods now usually falls under the purview of specially designated government agencies in most developed countries.
The 1970s saw a resurgence in the use of livestock guardian dogs and the development of new methods of predator control by sheep producers, many of them non-lethal. Donkeys and guard llamas have been used since the 1980s in sheep operations, using the same basic principle as livestock guardian dogs. Interspecific pasturing, usually with larger livestock such as cattle or horses, may help to deter predators, even if such species do not actively guard sheep. In addition to animal guardians, contemporary sheep operations may use non-lethal predator deterrents such as motion-activated lights and noisy alarms.

Sheep are an important part of the global agricultural economy. However, their once vital status has been largely replaced by other livestock species, especially the pig, chicken, and cow. China, Australia, India, and Iran have the largest modern flocks, and serve both local and exportation needs for wool and mutton. Other countries such as New Zealand have smaller flocks but retain a large international economic impact due to their export of sheep products. Sheep also play a major role in many local economies, which may be niche markets focused on organic or sustainable agriculture and local food customers. Especially in developing countries, such flocks may be a part of subsistence agriculture rather than a system of trade. Sheep themselves may be a medium of trade in barter economies.
Domestic sheep provide a wide array of raw materials. Wool was one of the first textiles, although in the late 20th century wool prices began to fall dramatically as the result of the popularity and cheap prices for synthetic fabrics. For many sheep owners, the cost of shearing is greater than the possible profit from the fleece, making subsisting on wool production alone practically impossible without farm subsidies. Fleeces are used as material in making alternative products such as wool insulation. In the 21st century, the sale of meat is the most profitable enterprise in the sheep industry, even though far less sheep meat is consumed than chicken, pork or beef.
Sheepskin is likewise used for making clothes, footwear, rugs, and other products. Byproducts from the slaughter of sheep are also of value: sheep tallow can be used in candle and soap making, sheep bone and cartilage has been used to furnish carved items such as dice and buttons as well as rendered glue and gelatin. Sheep intestine can be formed into sausage casings, and lamb intestine has been formed into surgical sutures, as well as strings for musical instruments and tennis rackets. Sheep droppings, which are high in cellulose, have even been sterilized and mixed with traditional pulp materials to make paper. Of all sheep byproducts, perhaps the most valuable is lanolin: the waterproof, fatty substance found naturally in sheep's wool and used as a base for innumerable cosmetics and other products.
Some farmers who keep sheep also make a profit from live sheep. Providing lambs for youth programs such as 4-H and competition at agricultural shows is often a dependable avenue for the sale of sheep. Farmers may also choose to focus on a particular breed of sheep in order to sell registered purebred animals, as well as provide a ram rental service for breeding. A new option for deriving profit from live sheep is the rental of flocks for grazing; these "mowing services" are hired in order to keep unwanted vegetation down in public spaces and to lessen fire hazard.
Despite the falling demand and price for sheep products in many markets, sheep have distinct economic advantages when compared with other livestock. They do not require expensive housing, such as that used in the intensive farming of chickens or pigs. They are an efficient use of land; roughly six sheep can be kept on the amount that would suffice for a single cow or horse. Sheep can also consume plants, such as noxious weeds, that most other animals will not touch, and produce more young at a faster rate. Also, in contrast to most livestock species, the cost of raising sheep is not necessarily tied to the price of feed crops such as grain, soybeans and corn. Combined with the lower cost of quality sheep, all these factors combine to equal a lower overhead for sheep producers, thus entailing a higher profitability potential for the small farmer. Sheep are especially beneficial for independent producers, including family farms with limited resources, as the sheep industry is one of the few types of animal agriculture that has not been vertically integrated by agribusiness. However, small flocks, from 10 to 50 ewes, often are not profitable because they tend to be poorly managed. The primary reason is that mechanization is not feasible, so return per hour of labor is not maximized. Small farm flocks generally are used simply to control weeds on irrigation ditches or maintained as a hobby.
Shoulder of lamb
Sheep meat and milk were one of the earliest staple proteins consumed by human civilization after the transition from hunting and gathering to agriculture. Sheep meat prepared for food is known as either mutton or lamb, and approximately 540 million sheep are slaughtered each year for meat worldwide. "Mutton" is derived from the Old French moton, which was the word for sheep used by the Anglo-Norman rulers of much of the British Isles in the Middle Ages. This became the name for sheep meat in English, while the Old English word sceap was kept for the live animal. Throughout modern history, "mutton" has been limited to the meat of mature sheep usually at least two years of age; "lamb" is used for that of immature sheep less than a year.
In the 21st century, the nations with the highest consumption of sheep meat are the Arab states of the Persian Gulf, New Zealand, Australia, Greece, Uruguay, the United Kingdom and Ireland. These countries eat 14–40 lbs (3–18 kg) of sheep meat per capita, per annum. Sheep meat is also popular in France, Africa (especially the Arab world), the Caribbean, the rest of the Middle East, India, and parts of China. This often reflects a history of sheep production. In these countries in particular, dishes comprising alternative cuts and offal may be popular or traditional. Sheep testicles—called animelles or lamb fries—are considered a delicacy in many parts of the world. Perhaps the most unusual dish of sheep meat is the Scottish haggis, composed of various sheep innards cooked along with oatmeal and chopped onions inside its stomach. In comparison, countries such as the U.S. consume only a pound or less (under 0.5 kg), with Americans eating 50 pounds (22 kg) of pork and 65 pounds (29 kg) of beef. In addition, such countries rarely eat mutton, and may favor the more expensive cuts of lamb: mostly lamb chops and leg of lamb.
Though sheep's milk may be drunk rarely in fresh form, today it is used predominantly in cheese and yogurt making. Sheep have only two teats, and produce a far smaller volume of milk than cows. However, as sheep's milk contains far more fat, solids, and minerals than cow's milk, it is ideal for the cheese-making process. It also resists contamination during cooling better because of its much higher calcium content. Well-known cheeses made from sheep milk include the feta of Bulgaria and Greece, Roquefort of France, Manchego from Spain, the pecorino romano (the Italian word for "sheep" is pecore) and ricotta of Italy. Yogurts, especially some forms of strained yogurt, may also be made from sheep milk. Many of these products are now often made with cow's milk, especially when produced outside their country of origin. Sheep milk contains 4.8% lactose, which may affect those who are intolerant.
As with other domestic animals, the meat of uncastrated males is inferior in quality, especially as they grow. A "bucky" lamb is a lamb which was not castrated early enough, or which was castrated improperly (resulting in one testicle being retained). These lambs are worth less at market.
In science
Sheep are generally too large and reproduce too slowly to make ideal research subjects, and thus are not a common model organism. They have, however, played an influential role in some fields of science. In particular, the Roslin Institute of Edinburgh, Scotland used sheep for genetics research that produced groundbreaking results. In 1995, two ewes named Megan and Morag were the first mammals cloned from differentiated cells, also referred to as gynomerogony. A year later, a Finnish Dorset sheep named Dolly, dubbed "the world's most famous sheep" in Scientific American, was the first mammal to be cloned from an adult somatic cell. Following this, Polly and Molly were the first mammals to be simultaneously cloned and transgenic.
As of 2008, the sheep genome has not been fully sequenced, although a detailed genetic map has been published, and a draft version of the complete genome produced by assembling sheep DNA sequences using information given by the genomes of other mammals. In 2012, a transgenic sheep named "Peng Peng" was cloned by Chinese scientists, who spliced his genes with that of a roundworm (C. elegans) in order to increase production of fats healthier for human consumption.
In the study of natural selection, the population of Soay sheep that remain on the island of Hirta have been used to explore the relation of body size and coloration to reproductive success. Soay sheep come in several colors, and researchers investigated why the larger, darker sheep were in decline; this occurrence contradicted the rule of thumb that larger members of a population tend to be more successful reproductively. The feral Soays on Hirta are especially useful subjects because they are isolated.
Domestic sheep are sometimes used in medical research, particularly for researching cardiovascular physiology, in areas such as hypertension and heart failure. Pregnant sheep are also a useful model for human pregnancy, and have been used to investigate the effects on fetal development of malnutrition and hypoxia. In behavioral sciences, sheep have been used in isolated cases for the study of facial recognition, as their mental process of recognition is qualitatively similar to humans.
Cultural impact
Sheep have had a strong presence in many cultures, especially in areas where they form the most common type of livestock. In the English language, to call someone a sheep or ovine may allude that they are timid and easily led. In contradiction to this image, male sheep are often used as symbols of virility and power; the logos of the Los Angeles Rams football team and the Dodge Ram pickup truck allude to males of the bighorn sheep, Ovis canadensis.
Counting sheep is popularly said to be an aid to sleep, and some ancient systems of counting sheep persist today. Sheep also enter in colloquial sayings and idiom frequently with such phrases as "black sheep". To call an individual a black sheep implies that they are an odd or disreputable member of a group. This usage derives from the recessive trait that causes an occasional black lamb to be born into an entirely white flock. These black sheep were considered undesirable by shepherds, as black wool is not as commercially viable as white wool. Citizens who accept overbearing governments have been referred to by the Portmanteau neologism of sheeple. Somewhat differently, the adjective "sheepish" is also used to describe embarrassment.
In heraldry
In British heraldry, sheep appear in the form of rams, sheep proper and lambs. These are distinguished by the ram being depicted with horns and a tail, the sheep with neither and the lamb with its tail only. A further variant of the lamb, termed the Paschal lamb, is depicted as carrying a Christian cross and with a halo over its head. Rams' heads, portrayed without a neck and facing the viewer, are also found in British armories. The fleece, depicted as an entire sheepskin carried by a ring around its midsection, originally became known through its use in the arms of the Order of the Golden Fleece and was later adopted by towns and individuals with connections to the wool industry. A sheep on a blue field is depicted on the greater/royal arms of the king of Denmark to represent the Faroe Islands. In 2004 a modernized arms has been adopted by the Faroe Islands, which based on a 15th century coat of arms.
Religion and folklore
In antiquity, symbolism involving sheep cropped up in religions in the ancient Near East, the Mideast, and the Mediterranean area: Çatalhöyük, ancient Egyptian religion, the Cana'anite and Phoenician tradition, Judaism, Greek religion, and others. Religious symbolism and ritual involving sheep began with some of the first known faiths: Skulls of rams (along with bulls) occupied central placement in shrines at the Çatalhöyük settlement in 8,000 BCE. In Ancient Egyptian religion, the ram was the symbol of several gods: Khnum, Heryshaf and Amun (in his incarnation as a god of fertility). Other deities occasionally shown with ram features include the goddess Ishtar, the Phoenician god Baal-Hamon, and the Babylonian god Ea-Oannes. In Madagascar, sheep were not eaten as they were believed to be incarnations of the souls of ancestors.
There are many ancient Greek references to sheep: that of Chrysomallos, the golden-fleeced ram, continuing to be told through into the modern era. Astrologically, Aries, the ram, is the first sign of the classical Greek zodiac, and the sheep is the eighth of the twelve animals associated with the 12-year cycle of in the Chinese zodiac, related to the Chinese calendar. It is said in Chinese traditions that Hou ji sacrificed sheep. Mongolia, shagai are an ancient form of dice made from the cuboid bones of sheep that are often used for fortunetelling purposes.
Sheep play an important role in all the Abrahamic faiths; Abraham, Isaac, Jacob, Moses, and King David were all shepherds. According to the Biblical story of the Binding of Isaac, a ram is sacrificed as a substitute for Isaac after an angel stays Abraham's hand (in the Islamic tradition, Abraham was about to sacrifice Ishmael). Eid al-Adha is a major annual festival in Islam in which sheep (or other animals) are sacrificed in remembrance of this act. Sheep are occasionally sacrificed to commemorate important secular events in Islamic cultures. Greeks and Romans sacrificed sheep regularly in religious practice, and Judaism once sacrificed sheep as a Korban (sacrifice), such as the Passover lamb. Ovine symbols—such as the ceremonial blowing of a shofar—still find a presence in modern Judaic traditions.
Collectively, followers of Christianity are often referred to as a flock, with Christ as the Good Shepherd, and sheep are an element in the Christian iconography of the birth of Jesus. Some Christian saints are considered patrons of shepherds, and even of sheep themselves. Christ is also portrayed as the Sacrificial lamb of God (Agnus Dei) and Easter celebrations in Greece and Romania traditionally feature a meal of Paschal lamb. A church leader is often called the pastor, which is derived from the Latin word for shepherd. In many western Christian traditions bishops carry a staff, which also serves as a symbol of the episcopal office, known as a crosier, which is modeled on the shepherd's crook.
Sheep are key symbols in fables and nursery rhymes like The Wolf in Sheep's Clothing, Little Bo Peep, Baa, Baa, Black Sheep, and Mary Had a Little Lamb; novels such as George Orwell's Animal Farm and Haruki Murakami's A Wild Sheep Chase; songs such as Bach's Sheep may safely graze (Schafe können sicher weiden) and Pink Floyd's "Sheep", and poems like William Blake's "The Lamb".
Bellydance is the name commonly used in Western countries to apply to traditional Middle Eastern dance, specifically Egyptian ghawazi dance in the 19th century, and raqs sharqi in the 20th century. The term is sometimes extended to include all traditional Middle Eastern dances. The term is somewhat misleading, as belly movements are only a small part of the dance. The most featured part of the body is usually the hips.
Belly dance takes different forms in different regions, both in costume and dance style, and new styles have evolved in the West as its popularity has spread globally.
The ghawazee of were travelling female dancers of Dom (Gypsy) ethnicity in Egypt during the 18th to 19th centuries. They were banished from Cairo to Upper Egypt by Muhammad Ali in the 1830s. The dance style of the ghawazee was popularized in Europe under the term "belly-dance" in 19th-century
Most of the movements in belly dancing involve isolating different parts of the body (hips, shoulders, chest, stomach etc.), similar to the isolations used in jazz ballet. In much of bellydance there is a focus upon the core muscles of the body producing the movement rather than the external muscles of the body. Egyptian and Lebanese bellydance in particular emphasise the need for movemements to originate in the muscles of the back.
The costume most associated with belly dance is the bedlah (Arabic for "suit").
The bedlah style includes a fitted top (usually with a fringe of beads or coins), a fitted hip belt (again with a fringe of beads or coins), and a skirt or harem pants. The top and belt may be richly decorated with beads, sequins, braid and embroidery. The belt may be a separate piece, or sewn into a skirt.
The hip belt is a broad piece of fabric worn low on the hips. It may have straight edge, or may be curved or angled. The top usually matches the belt. The classic harem pants are full and gathered at the ankle, but there are many variations. Sometimes pants and a sheer skirt are worn together. Skirts may be flowing creations made of multiple layers of one color sheer fabric chiffon.
Since the 1950s, it has been illegal in Egypt for raqs sharqi dancers to perform publicly with their midriff uncovered or to display excessive skin. It is therefore becoming more common to wear a long, figure-hugging lycra one-piece gown with strategically placed cut-outs filled in with sheer, flesh-coloured fabric. If a separate top and skirt are worn, a belt is rarely used and any embellishment is embroidered directly on the tight, sleek lycra skirt. A sheer body stocking must be worn to cover the midsection. Egyptian dancers traditionally dance in bare feet, but these days often wear shoes and even high heels.
Khan al Khalili, the major traditional souk (open market) in Cairo, is the world's most popular spot for bellydance wear / Raqswear and continues to attract millions of visitors every year.
As there is no prohibition on showing the stomach in Lebanon, the bedleh style is more common. The skirts tend to be sheer, although many Lebanese belly dancers opt for the shirwal pants with a top. The veil is more widely used and the veil matches the outfit. High heels are a trademark of Lebanese belly dancers.
Turkish dancers also wear bedleh style costumes. In the 80s and 90s a 'stripperesque' costume style developed, with skirts designed to display both legs up to the hip, and plunging tops. Such styles still exist in some venues but there are also many Turkish belly dancers who wear more moderate costumes. Even so, Turkish belly dance costumes reflect the playful, flirty style of Turkish belly dance.
In Egypt, three main forms of the traditional dance are associated with belly dance, called Baladi, Sharqi and Sha'abi.
Baladi is a folk style of dance from the Arab tribes who settled in Upper Egypt. The term has come to refer to the folk dance still performed by the working classes of urbanised Egypt. Dance which more rigorously tries to uphold folk traditions from the countryside or from specific tribes will often be referred to as Ghawahzee. The Ghawahzee dancers have also been known to be at the heart of the conflict in Egypt over the propriety of publicly performed dance. The well-reputed Mazin sisters are widely held to be the last authentic performers of Ghawahzee dance. Khayreyya Mazin is currently the last of these dancers still teaching and performing as of 2009.
Sharqi is based on the baladi style but was further developed by Samia Gamal, Tahiya Karioka, Naima Akef, and other dancers who rose to fame during the golden years of the Egyptian film industry. This has come to be considered the classical style of dance in Egypt. These dancers were famous not only for their role in Egyptian films, but also for their performances at the "Opera Casino" opened in 1925 by Badia Masabni. This venue was a popular place for influential musicians and choreographers from both the US and Europe. Later dancers who were influenced by these artists are Sohair Zaki, Fifi Abdou, and Nagwa Fouad. All rose to fame between 1960 and 1980, and are still popular today. Some of these later dancers were the first to choreograph and perform dances using a full 'orchestra' and stage set-up, which had a huge influence upon what is considered the 'classical' style.
Sha'abi refers to the poorer, commoner sections of Cairo. The name came to characterize the style of music enjoyed in such neighborhoods. The style is somewhat rougher and more playful than the rest of Egyptian pop music. Sha'abi dance is Egyptian belly dance performed to such music, typically performed more assertively sexual than is classical raqs sharqi.

As larvas vão alimentando-se dos órgãos e da hemolinfa da barata até que sobre apenas o exoesqueleto.
These colorful, tiny parasitic wasps sting American cockroaches twice, once in the midsection to prevent them from running away, and a second time directly in the brain, to make the insects sluggish and zombielike. The wasps then drag the roaches by their antenna, akin to a human pulling a dog on a leash, into a protected nook and lay an egg on the roach. The egg ultimately hatches into larvae that devour the roach from the inside out.
This gorgeous animal, which measures just under an inch from mandibles to tail, lives across much of Africa and Asia, as well as a few Pacific Islands. Don’t be fooled by its lovely glittering appearance, though. This is a deeply sinister creature. Jewel wasps don’t rear their young in a familiar paper nest. For them, home is the inside of a cockroach.

A large owl butterfly caterpillar (Caligo sp.) found on a leaf after sunset. This individual looks large enough to pupate, but sadly it is doubtful that it lived long enough to complete its lifecycle. Why? Because it appears to have been parasitized. There's a cluster of white oblong shapes affixed to the caterpillar's midsection, and I suspect they're Tachinid fly eggs. They look just like the glued-on Tachinid eggs that I dislodged from a Cecropia moth caterpillar before they could hatch. See the next photo for a close-up of the eggs on this caterpillar.

“Mister Reese! Come quickly!”
The young man immediately stands up from the shaded encampment, but pauses, rolling his right, gloved wrist in the other hand. A curious ratcheting noise emits as he massages. Fortifying himself, he turns on his heels and makes for the site from which he was called. As he cuts through the hip-height shrubs choking the hillside, Doctor Andonis Bal emerges from his tent, jogging in Reese’s direction.
“Didn’t I tell you?” Andonis rags his companion slyly. “She would find it without us.”
Reese emulates his tone, with something comparative to a chuckle. “I do recall.”
Andonis slaps a hand on the man’s shoulder, and the pair of them kick up more dust. The Mediterranean sun beats down on the exposed landscape. On all sides, eaten out of the terrain, are recently-abandoned excavations; just one is occupied, by a half-dozen men pushing back their hats and watching the sole woman, kneeling, brushing away at the innermost rock of the man-made pocket.
She hears the final two men’s approach, and quits her laboring.
“Your work is beautiful, Dr. Bal,” Andonis carols, arms open.
“Whenever it is emancipated from your fawning, Dr. Bal,” the woman attests.
They kiss, at length. Reese coughs, sidestepping the couple to examine the headway made. Neatly defined from the earth by Andonis’ wife are four inscribed slabs, positioned at their corners to create a wide trapezoidal frame; no higher than Reese’s knees even if it were not set diagonally in its grave, but as long across as could see two arm spans, end to end, pass through it.
The mouth has yet to be cleared of rubble. Waiting for no indication from either archaeologist to finalize the task, Reese scuffs a long-unpolished boot against the barricade. It falls with ease, and the clods avalanche into the chasm behind.
It is indeed grander than its entrance. Unveiled is a preposterously steep, obsidian staircase plummeting through the crust. The steps fan out, their breadth tripling from that of the ingress, and walls vaulting arrestingly, impossibly, in the dark. There is no true ornamentation or luxurious quality to the architecture, only its sheer scale ingrains in its spectators awe, and——gnawing at their aggregate subconscious——a primordial foreboding.
Those assembled had been ducking in closely to the entrance in order to marvel, but Reese perceptively commands the others to move well away when his nose catches the twinge of sulfur dioxide.
“There are no volcanoes in this region of Greece,” observes one of the more enlightened workers, as everyone cautiously breathes through clothing and handkerchiefs; each of them, confounded as the next.
"Neither should it be here, at the brink, my friend," Reese swallows. "Sulfur dioxide is heavier than air."
If not for Reese, the company would have moved away still, for another smell, all the more acrid, and corporeal, is further cause to retreat. It is a smell no one feels constrained to name.
“Mr. Reese…” Andonis pronounces, now confident in introducing their discovery, but with a deficit of apropos ceremony,
“… the door to Hades.”
“We can be sure of this…” Reese mutters, indefinitely a question. He tilts his head this way and that, trying to overcome the trance that the pit instilled.
Andonis’ wife defends, resenting Reese’s doubtfulness, indirect as it was. “That was our promise to your benefactor,” she gestures at some of the advanced mining equipment lying around, in reference to their supplier. “We deal in truth.”
Andonis is much too excited to admonish either of them, starting to prattle on about his own and his partner’s prowess. “Everyone who would even believe in such things has looked for a gateway where myth places them. Along the Acheron. Lerna. Cape Matapan… Angelika and I, too, began our search there.”
The two make eyes at each other. Reese stands by, resigned.
"We unearthed there a stele, a… tablet,” Andonis simplifies, “whose engraving gave only vague geographical hints that led us north…”
The archaeologist takes a moment to admire at their majestic scenery.
“Here, to this coastline. And though we could not be certain of such a primitive map…”
Andonis hurriedly traipses back to the low cave and, regardless of lingering vapors, bends in to where Angelika had last been restoring the carved structure. He unfolds some parchment from a breast pocket, and points between it and the stone, at the same jagged insignia present on both. “This etching does not lie. It is no Grecian symbol, not in recorded history. Yet here it is, twice over. On Grecian artifacts.”
A hungry grin materializes on Angelika’s sharp features, as she concludes Andonis’ assertions of their success. “Stelae were used to mark boundaries, or to immortalize the sites of great battles, and in turn, a great loss of life. This is a headstone in homage to innumerable generations. The nonpareil monument to the Underworld.”
While the drained workers seem shaken by Angelika’s intensity, Reese’s posture is unchanged.
“I loathe to send for my superior when we are without more substantial… Well… I see no evidence that this marking was fabricated,” he weighs, as if none of the Bals’ impassioned theorizing had influenced Reese’s verdict. He nods.
“Yes, I think we are ready to press on. Tomorrow, if you will both please be prepared. She will be bringing all other necessary provisions.“
The Doctors Bal give a wary glance to one another. Angelika is the first to suppress Reese and his men, in their victory.
“The gods are real, Mr. Reese.”
Reese adjusts a sleeve nonchalantly. “That is my hope,” he replies, with some disdain showing in the crook of his mouth.
Deathly silence, as Andonis rejoins Angelika. Reese almost leaves for the camp again before he registers the nerves of the husband and wife, and addresses the apparent hypocrisy.
“Surely you would not have me believe you are both to forego this grand venture. It is obvious that there is no one here more exhilarated.”
“Crossing that threshold is folly,” Andonis dismisses. “You let us believe the secrecy of our research was to ensure our claim to the eventual presentation. The glory of the find has been our concern, not—”
“You expected us,” Angelika summarizes, as the more plainly distressed of the two, “to partake in a… a fool’s katabasis. To share in whatever calamity you will wreak on yourselves and the world.”
The air sours, only now it is not due to the eldritch portal quietly attending the whole affair.
“Have you… reason, to deem my acquaintances’ intentions as anything other than saintly?” Reese dares.
Andonis’ eye flickers. “Your English is not so convincing as you would like it to be. Your accent.”
“Well, it is better than my American.”
“Your friends are not even as good as you.”
A self-conscious murmur wafts from Reese’s men, at Andonis’ critique. Reese has an earnest laugh this time. He drops all affectations.
“It was for your benefit, of course. Naturally you would have a degree of prejudice against a man of my true background. And, in that sad scenario, we would not have done such marvelous work together.”
Angelika looks inclined to throttle Reese then and there, but the understated man simply gazes out over the cove.
“To cut ties now,” Reese tsks, “will not do. She ah… Your employer, I know, would be receptive to renegotiating allowances, if only you named your price to take the next step. We are still so in need of your combined expertise, now that fiction is fact. ‘What lies beneath these ancient lands?’, why, I could not guess. My colleagues and I, our educations… pale, in comparison.”
…
“I beg you to make a… cultured decision,“ Reese smiles inappreciably; his appeal, not the least bit contrite.
Angelika withdraws one step, as though she means to bodily protect the pit entrance. Andonis is a statue, letting a murky history come flooding back to his mind’s eye; Reese’s disguised venom, opening old wounds as the sickening seconds pass, until Andonis’ rage inevitably outpaces his fears.
“Men wearing badges of death, proclaiming order. Lunatics playing god… My wife and I have survived a number of monsters in our lifetime. We have our scars and our curses, and today, Mr. Reese, we are wiser, and stronger for it all. Interpret that as you may.”
Reese does just that.
“I see,” he meditates. “Then, perhaps, this can all be fixed,”
One of the burlier hired hands grabs Angelika by a shoulder and under the jaw.
“if it is you who are begging.”
Andonis makes to spring at Reese, only for a calculated shake from Reese’s head to put everyone on hold. Then, another motion: This one, for Andonis to turn to his wife. He abides, tentative, dreading that locking eyes with her would be a signal for their enemies to seal her fate. But all persists in faux equilibrium; Reese, with his back to the sea; Angelika, restrained near the cave; Andonis, their median. It is seemingly Angelika’s word that Reese awaits.
Her husband silently prays she will agree to their oppressor’s terms, so that they might live to renege the partnership another day. This prayer relies on a fanciful ignorance of who Angelika Bal was and had always been in Andonis’ life, and so it is dashed when his eyes do catch hers, and he sees the inferno he knew he would. Andonis’ head bows.
Angelika’s captor comes to realize that he is not keeping her in place; rather, that she is standing perfectly, comfortably stationary. At that, what little force he tries to exert upon her bare neck and arm results in biting sensations on his own body. He backs off a small ways. Angelika shuts her eyes behind a curtain of black hair——which was not nearly so long or greasy just moments ago——and speaks with an incorrect voice.
“Humans beg, boy.”
The eyes of the startled man behind Angelika align with Andonis’, long enough for the unwitting thug to take in the turbulent mixture of sadness and spite filling the doctor. Then, a Stygian flare erupts from within the sockets of Andonis’ skull. As subtly as Angelika’s own transformation, Reese’s man, in a perverse sense of mercy, now stands as an earthen block in the shape of a man: Dead, by every definition.
Before a yell can exit even one of the men bearing witness to the horror, Angelika spins and effortlessly shoulders the humanoid pillar. It fragments into projectiles that incapacitate two more men; one chunk clips an unfortunate’s knee, while another of greater size pounds its feeble victim into the hill, crushing a lung.
Simultaneously, Andonis lashes his head back at Reese. Andonis’ hair shifts like seaweed in a torrent, and from between the curls sprout multitudes of bleached, mutated vipers, spitting and recoiling with tensity.
Reese sneers, unnerved, and holds up his right arm in front of his face.
The snakes latch onto the offering, their toxins pouring as would uncorked wine. A second yank from Andonis’ neck, and Reese is slung handily by his appendage across an unaccommodating rock.
The three of Reese’s followers still on their feet have produced pistols too late, for Angelika jets straight up into the blinding sun. At the apex of her tremendous jump, the skin of her arms frills out into dagger-like feathers, blotched and serrated from overuse. The harpy executes a lethal dive, trailing an unnatural wind that rips into solid ground. Angelika veers horizontally with a foot to spare, and the sand all around becomes razorblades in her wake. None of her opponents get a clear shot: One loses an ear. Angelika’s wing severs another’s forearm in the onslaught.
Adrenaline pumping, Reese pulls a Luger from underneath his coat with his free hand, firing blind as he averts his line of sight from Andonis’. The last of the bullets zips clean through Andonis’ bicep. Whipping away his many jaws, Andonis punts through the rock and into Reese, in his center of mass. Reese is sent cartwheeling through a stream of debris, halfway back to camp.
Angelika circles back, reveling in the torturous sounds below, and skewers a recovering gunman through the pelvis with the sickle-shaped claws protruding from her split boots. In passing, she flattens her catch on the unburied stone doorway.
The one-armed henchman dawdles amidst the storm of dust, stunned, and soon enough he beholds the sunken eyes of whatever Andonis is now. Again, a horrific flash follows, and the ill-prepared soldier is calcified on the spot. Andonis plows directly through him before the transfiguration is completed, and the misshapen cocoon is blasted into powder and gore. Continuing his rampage into one more debilitated man, Andonis compels his snakes to sink their fangs into the chest, shoulders, neck and face in front of them. Their prey is hoisted up, gargling thickened blood as acidic saliva takes its place in his veins. In seconds the body is pulpy and bloated, resembling a florid wax. The serpents relinquish it, and it meets the ground in the way a sack of lumber does.
The man with a collapsed lung finally wrests his weapon from his belt, despite his entrapment, but——in no position or state of mind to take proper aim at anything——Angelika swiftly plucks most of him from his prospective, shallow grave. Her grip gouges his abdomen, stringing entrails as chaff would fall from a plane. She discards him over a rise.
An ear-splitting shot sounds.
From one elbow, down the wing and partway into her midsection, Angelika has a perforation seared out of her.
Andonis can only watch, and scream, as his true love’s form flutters gracelessly to the earth. She is gone before the impact. As is Andonis. A tenderness, once cultivated in him by a kindred spirit which had for years matched Andonis’ dedication, frustrations and desires at every turn, is suddenly torn asunder. What had up to this point been concentrated wrath welling up in him is now simplified, to something purely animalistic, rabid. A life that only had death to live for.
Andonis roars, thrashing about recklessly with the deadly glow blazing forth from his eyes. But Reese, from his vantage on the slope back to the sea, advisedly cowers from the array; in the meantime, he retracts a smoking cannon back into his mechanical right arm. The artificial extension independently retrains itself on Andonis with the aid of a thermal scope, then the hand launches from the wrist, buzzing through the air at the end of a cord which spools from the apparatus.
Slamming into Andonis’ neck and collarbone, the fingers relentlessly crimp his airway, successfully checking his optic attack. On the verge of blacking out from the violent interruption, Andonis is dragged uphill by Reese, who joyously, cruelly reels in the line.
Andonis comes to a stop face-down, lending Reese the opportunity to kneel on his spine and the nearest arm, and in one fluid sweep, Reese slides a knife from out his boot and into the archaeologist’s side. The reptilian growths on Andonis’ head judder reactively, and again shred at Reese’s right arm——still locked into Andonis’ flesh——but the entire limb is a durable casing, hindered neither by their teeth nor poison. Past a slew of broken ribs, Reese grins.
“The Gorgon curse of Athena,” he drools savagely. “Oh my friend, you invigorate me… but you could not surprise me.”
The knife deepens. What proceeds is a full minute of Andonis’ gut-wrenching howls, bawling, floundering. But, whether from a spent body or soul, Andonis calms from his delirium. He pants. He bleeds. Envisioning his Angelika’s face one last time, he whispers to Reese,
“May you find down there… an end more lowly and unutterable… than we could give you.”
Reese apathetically crushes bone under his claw. Andonis’ head wobbles free in the dirt. The killer sighs, releasing the stained wad of skin from his cold grip. Crouching, he toys with one of the few snakes still writhing on the dead scalp. All the while, the more severely wounded of Reese’s two surviving men has been pulling himself back to the dig, mere, excruciating inches at a time. There is virtually nothing left of him beneath his waist. His breaths are like scraping granite.
“Mein Herr—”
Without notice, Reese turns with the severed head dangling in his fist, and the wounded man stiffens, meeting its ghastly expression. But Andonis’ eyes remain empty wells. No corrupt metamorphosis takes place. Instead, a far more terrestrial, prosaic change——the trembling of a shocked and mangled soldier drawing to a close——comes to pass.
“Bedauerlich,” Reese bemoans the ineffectual remains in hand. “I think I shall keep it, in any case.”
He sets the head down like a prized vase.
“If you would please contact the baroness,” Reese dictates to his lone underling, while picking destroyed glove away from his prosthetic, “advise her: The Englishwoman is no longer expendable, that she must accompany our… ‘katabasis’.”
“Jawohl, Herr Riese.”
‘Riese’, with a sobering stare, belatedly corrects the subordinate’s informal designation for him.
“… Roter Panzer.”
The Red Panzer stands up straighter, gratified.
A side view of this dress shows off my slimmer figure. Yes, I have indeed slimmed down a bit this year. And while I still don't have the most fit of bodies, and I still haven't entirely sworn off sugar (much to my ever loving shame), having a smaller size midsection is a great feeling.
The extended-range C-130E model entered service in 1962 after it was developed as an interim long-range transport for the Military Air Transport Service. Essentially a B-model, the new designation was the result of the installation of 1,360 US gal (5,150 L) Sargent Fletcher external fuel tanks under each wing's midsection and more powerful Allison T56-A-7A turboprops. The hydraulic boost pressure to the ailerons was reduced back to 2,050 psi (14.1 MPa) as a consequence of the external tanks' weight in the middle of the wingspan. The E model also featured structural improvements, avionics upgrades and a higher gross weight. Australia took delivery of 12 C130E Hercules during 1966–67 to supplement the 12 C-130A models already in service with the RAAF. Sweden and Spain fly the TP-84T version of the C-130E fitted for aerial refueling capability.

It is with a heavy heart that I announce the passing of our beloved resident Eastern Water Dragon, Liz. When we moved to our property in the Blue Mountains in 2019, we discovered it was already inhabited by a breeding pair of Dragons (who we named Bob and Liz). Graciously, they agreed to share the space with us and over time came to feel safer around us. Bob went from terrified to merely wary and a little skittish. Liz, on the other hand, went from wary to exceptionally comfortable with our company. She was always recognizable by the kink toward the end of her tail, a sign of a past injury we will never know anything about.
We never fed them, or did any “taming” activities; instead, we respected their personal space, spoke to them kindly and worked around them when in the garden. Liz would watch Joe put in plants, occasionally nabbing a beetle grub he accidentally dug up. She was friendly, curious and patient and a constant fixture on the property. Bob maintained the larger territory that was our street, but more often than not, Liz could be found on her favourite rock, soaking up the sun. We adored these reptiles and considered them part of our family. We watched Liz get pregnant each year, delighting in the fact a new generation was on the way. We missed them in winter, and were thrilled at the first sighting in early spring. As I am chronically ill and spend most of my time alone at home, Liz provided much needed companionship for me, and made me feel less lonely. She was a great listener and would watch me photograph my bees while only a foot or so away from me. She was our friend.
Tragically, on Wednesday the 6th December, Liz was run over and killed while crossing the road from our neighbour’s place to ours. Joe found her in the evening when setting off to the shops, and we were both devastated. The force of the vehicle ruptured her lower midsection, and 4 of her nearly fully-developed eggs were ejected. We gathered them up, along with her body, and took her to the local vet who offered to incubate the eggs and autopsy her to check if there were more. Her body was still supple, so she had been recently killed, and one of the eggs landed in grass. It was a warm day, so they may have survived. We won’t know, and have asked not to find out from the vet, as it is too painful for us. We put in a report with Wires.
We’re both deeply saddened and are grieving. I have lost many pets, and this felt just as agonizing as any of their deaths did. I am considering petitioning council for signs to remind people to drive slowly on streets adjacent to bush, to spare our precious wildlife. I dedicate this post to Liz and the wonderful memories she gave us. Rest in peace, beautiful one. May your children live longer lives. Thank you to everyone who has read this. I know my Flickr community of naturalists will understand our loss.
Maize (/meɪz/ MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taino: mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits.
Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and corn syrup. The six major types of maize are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn. Sugar-rich varieties called sweet corn are usually grown for human consumption as kernels, while field corn varieties are used for animal feed, various corn-based human food uses (including grinding into cornmeal or masa, pressing into corn oil, and fermentation and distillation into alcoholic beverages like bourbon whiskey), and as chemical feedstocks. Maize is also used in making ethanol and other biofuels.
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2014, total world production was 1.04 billion tonnes. Maize is the most widely grown grain crop throughout the Americas, with 361 million metric tons grown in the United States alone in 2014. Genetically modified maize made up 85% of the maize planted in the United States in 2009. Subsidies in the United States help to account for its high level of cultivation of maize and its position as the largest producer in the world.
HISTORY
PRE-COLUMBIAN DEVELOPMENT
Maize is a cultigen; human intervention is required for it to propagate. Whether or not the kernels fall off the cob on their own is a key piece of evidence used in archaeology to distinguish domesticated maize from its naturally-propagating teosinte ancestor. Genetic evidence can also be used to determine when various lineages split.
Most historians believe maize was domesticated in the Tehuacán Valley of Mexico. Recent research in the early 21st century has modified this view somewhat; scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication.
An influential 2002 study by Matsuoka et al. has demonstrated that, rather than the multiple independent domestications model, all maize arose from a single domestication in southern Mexico about 9,000 years ago. The study also demonstrated that the oldest surviving maize types are those of the Mexican highlands. Later, maize spread from this region over the Americas along two major paths. This is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands.
Archaeologist Dolores Piperno has said:
A large corpus of data indicates that [maize] was dispersed into lower Central America by 7600 BP [5600 BC] and had moved into the inter-Andean valleys of Colombia between 7000 and 6000 BP [5000–4000 BC].
— Dolores Piperno, The Origins of Plant Cultivation and Domestication in the New World Tropics: Patterns, Process, and New Developments
Since then, even earlier dates have been published.
According to a genetic study by Embrapa, corn cultivation was introduced in South America from Mexico, in two great waves: the first, more than 6000 years ago, spread through the Andes. Evidence of cultivation in Peru has been found dating to about 6700 years ago. The second wave, about 2000 years ago, through the lowlands of South America.
The earliest maize plants grew only small, 25-millimetre-long (1 in) corn cobs, and only one per plant. In Jackson Spielvogel's view, many centuries of artificial selection (rather than the current view that maize was exploited by interplanting with teosinte) by the indigenous people of the Americas resulted in the development of maize plants capable of growing several cobs per plant, which were usually several centimetres/inches long each. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica; they cooked, ground and processed it through nixtamalization. It was believed that beginning about 2500 BC, the crop spread through much of the Americas. Research of the 21st century has established even earlier dates. The region developed a trade network based on surplus and varieties of maize crops.
Mapuches of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times; however, potato was the staple food of most Mapuches, "specially in the southern and coastal [Mapuche] territories where maize did not reach maturity". Before the expansion of the Inca Empire maize was traded and transported as far south as 40°19' S in Melinquina, Lácar Department. In that location maize remains were found inside pottery dated to 730 ± 80 BP and 920 ± 60 BP. Probably this maize was brought across the Andes from Chile. The presence of maize in Guaitecas Archipelago (43°55' S), the southernmost outpost of pre-Hispanic agriculture, is reported by early Spanish explorers. However the Spanish may have misidentified the plant.
COLUMBIAN EXCHANGE
After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe and introduced it to other countries. Spanish settlers far preferred wheat bread to maize, cassava, or potatoes. Maize flour could not be substituted for wheat for communion bread, since in Christian belief only wheat could undergo transubstantiation and be transformed into the body of Christ. Some Spaniards worried that by eating indigenous foods, which they did not consider nutritious, they would weaken and risk turning into Indians. "In the view of Europeans, it was the food they ate, even more than the environment in which they lived, that gave Amerindians and Spaniards both their distinctive physical characteristics and their characteristic personalities." Despite these worries, Spaniards did consume maize. Archeological evidence from Florida sites indicate they cultivated it as well.
Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. Widespread cultivation most likely began in southern Spain in 1525, after which it quickly spread to the rest of the Spanish Empire including its territories in Italy (and, from there, to other Italian states). Maize had many advantages over wheat and barley; it yielded two and a half times the food energy per unit cultivated area, could be harvested in successive years from the same plot of land, and grew in wildly varying altitudes and climates, from relatively dry regions with only 250 mm (10 in) of annual rainfall to damp regions with over 5,000 mm (200 in). By the 17th century it was a common peasant food in Southwestern Europe, including Portugal, Spain, southern France, and Italy. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially in the form of polenta in Italy.
Names
The word maize derives from the Spanish form of the indigenous Taíno word for the plant, mahiz. It is known by other names around the world.
The word "corn" outside the US, Canada, Australia, and New Zealand refers to any cereal crop, its meaning understood to vary geographically to refer to the local staple. In the United States, Canada, Australia, and New Zealand, corn primarily means maize; this usage started as a shortening of "Indian corn". "Indian corn" primarily means maize (the staple grain of indigenous Americans), but can refer more specifically to multicolored "flint corn" used for decoration.
In places outside the US, Canada, Australia, and New Zealand, corn often refers to maize in culinary contexts. The narrower meaning is usually indicated by some additional word, as in sweet corn, sweetcorn, corn on the cob, baby corn, the puffed confection known as popcorn and the breakfast cereal known as corn flakes.
In Southern Africa, maize is commonly called mielie (Afrikaans) or mealie (English), words derived from the Portuguese word for maize, milho.
Maize is preferred in formal, scientific, and international usage because it refers specifically to this one grain, unlike corn, which has a complex variety of meanings that vary by context and geographic region. Maize is used by agricultural bodies and research institutes such as the FAO and CSIRO. National agricultural and industry associations often include the word maize in their name even in English-speaking countries where the local, informal word is something other than maize; for example, the Maize Association of Australia, the Indian Maize Development Association, the Kenya Maize Consortium and Maize Breeders Network, the National Maize Association of Nigeria, the Zimbabwe Seed Maize Association.
STRUCTURE AND PHYSIOLOGY
The maize plant is often 3 m (10 ft) in height, though some natural strains can grow 13 m (43 ft). The stem is commonly composed of 20 internodes of 18 cm (7 in) length. The leaves arise from the nodes, alternately on opposite sides on the stalk. A leaf, which grows from each node, is generally 9 cm (3+1⁄2 in) in width and 120 cm (3 ft 11 in) in length.
Ears develop above a few of the leaves in the midsection of the plant, between the stem and leaf sheath, elongating by around 3 mm (1⁄8 in) per day, to a length of 18 cm (7 in) with 60 cm (24 in) being the maximum alleged in the subspecies. They are female inflorescences, tightly enveloped by several layers of ear leaves commonly called husks. Certain varieties of maize have been bred to produce many additional developed ears. These are the source of the "baby corn" used as a vegetable in Asian cuisine.
The apex of the stem ends in the tassel, an inflorescence of male flowers. When the tassel is mature and conditions are suitably warm and dry, anthers on the tassel dehisce and release pollen. Maize pollen is anemophilous (dispersed by wind), and because of its large settling velocity, most pollen falls within a few meters of the tassel.
Elongated stigmas, called silks, emerge from the whorl of husk leaves at the end of the ear. They are often pale yellow and 18 cm (7 in) in length, like tufts of hair in appearance. At the end of each is a carpel, which may develop into a "kernel" if fertilized by a pollen grain. The pericarp of the fruit is fused with the seed coat referred to as "caryopsis", typical of the grasses, and the entire kernel is often referred to as the "seed". The cob is close to a multiple fruit in structure, except that the individual fruits (the kernels) never fuse into a single mass. The grains are about the size of peas, and adhere in regular rows around a white, pithy substance, which forms the ear. The maximum size of kernels is reputedly 2.5 cm (1 in). An ear commonly holds 600 kernels. They are of various colors: blackish, bluish-gray, purple, green, red, white and yellow. When ground into flour, maize yields more flour with much less bran than wheat does. It lacks the protein gluten of wheat and, therefore, makes baked goods with poor rising capability. A genetic variant that accumulates more sugar and less starch in the ear is consumed as a vegetable and is called sweet corn. Young ears can be consumed raw, with the cob and silk, but as the plant matures (usually during the summer months), the cob becomes tougher and the silk dries to inedibility. By the end of the growing season, the kernels dry out and become difficult to chew without cooking them tender first in boiling water.
Planting density affects multiple aspects of maize. Modern farming techniques in developed countries usually rely on dense planting, which produces one ear per stalk. Stands of silage maize are yet denser,[citation needed] and achieve a lower percentage of ears and more plant matter.
Maize is a facultative short-day plant and flowers in a certain number of growing degree days > 10 °C (50 °F) in the environment to which it is adapted. The magnitude of the influence that long nights have on the number of days that must pass before maize flowers is genetically prescribed and regulated by the phytochrome system.
Photoperiodicity can be eccentric in tropical cultivars such that the long days characteristic of higher latitudes allow the plants to grow so tall that they do not have enough time to produce seed before being killed by frost. These attributes, however, may prove useful in using tropical maize for biofuels.
Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). DIMBOA is a member of a group of hydroxamic acids (also known as benzoxazinoids) that serve as a natural defense against a wide range of pests, including insects, pathogenic fungi and bacteria. DIMBOA is also found in related grasses, particularly wheat. A maize mutant (bx) lacking DIMBOA is highly susceptible to attack by aphids and fungi. DIMBOA is also responsible for the relative resistance of immature maize to the European corn borer (family Crambidae). As maize matures, DIMBOA levels and resistance to the corn borer decline.
Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to be uprooted by severe winds.
While yellow maizes derive their color from lutein and zeaxanthin, in red-colored maizes, the kernel coloration is due to anthocyanins and phlobaphenes. These latter substances are synthesized in the flavonoids synthetic pathway from polymerization of flavan-4-ols by the expression of maize pericarp color1 (p1) gene which encodes an R2R3 myb-like transcriptional activator of the A1 gene encoding for the dihydroflavonol 4-reductase (reducing dihydroflavonols into flavan-4-ols) while another gene (Suppressor of Pericarp Pigmentation 1 or SPP1) acts as a suppressor. The p1 gene encodes an Myb-homologous transcriptional activator of genes required for biosynthesis of red phlobaphene pigments, while the P1-wr allele specifies colorless kernel pericarp and red cobs, and unstable factor for orange1 (Ufo1) modifies P1-wr expression to confer pigmentation in kernel pericarp, as well as vegetative tissues, which normally do not accumulate significant amounts of phlobaphene pigments. The maize P gene encodes a Myb homolog that recognizes the sequence CCT/AACC, in sharp contrast with the C/TAACGG bound by vertebrate Myb proteins.
The ear leaf is the leaf most closely associated with a particular developing ear. This leaf and above contribute 70% to 75% to 90% of grain fill. Therefore fungicide application is most important in that region in most disease environments.
ABNORMAL FLOWERS
Maize flowers may sometimes exhibit mutations that lead to the formation of female flowers in the tassel. These mutations, ts4 and Ts6, prohibit the development of the stamen while simultaneously promoting pistil development. This may cause inflorescences containing both male and female flowers, or hermaphrodite flowers.
GENETICS
Maize is an annual grass in the family Gramineae, which includes such plants as wheat, rye, barley, rice, sorghum, and sugarcane. There are two major species of the genus Zea (out of six total): Zea mays (maize) and Zea diploperennis, which is a perennial type of teosinte. The annual teosinte variety called Zea mays mexicana is the closest botanical relative to maize. It still grows in the wild as an annual in Mexico and Guatemala.
Many forms of maize are used for food, sometimes classified as various subspecies related to the amount of starch each has:
Flour corn: Zea mays var. amylacea
Popcorn: Zea mays var. everta
Dent corn : Zea mays var. indentata
Flint corn: Zea mays var. indurata
Sweet corn: Zea mays var. saccharata and Zea mays var. rugosa
Waxy corn: Zea mays var. ceratina
Amylomaize: Zea mays
Pod corn: Zea mays var. tunicata Larrañaga ex A. St. Hil.
Striped maize: Zea mays var. japonica
This system has been replaced (though not entirely displaced) over the last 60 years by multivariable classifications based on ever more data. Agronomic data were supplemented by botanical traits for a robust initial classification, then genetic, cytological, protein and DNA evidence was added. Now, the categories are forms (little used), races, racial complexes, and recently branches.
Maize is a diploid with 20 chromosomes (n=10). The combined length of the chromosomes is 1500 cM. Some of the maize chromosomes have what are known as "chromosomal knobs": highly repetitive heterochromatic domains that stain darkly. Individual knobs are polymorphic among strains of both maize and teosinte.
Barbara McClintock used these knob markers to validate her transposon theory of "jumping genes", for which she won the 1983 Nobel Prize in Physiology or Medicine. Maize is still an important model organism for genetics and developmental biology today.
The centromeres have two types of structural components, both of which are found only in the centromeres: Large arrays of CentC, a short satellite DNA; and a few of a family of retrotransposons. The B chromosome, unlike the others, contains an additional repeat which extends into neighboring areas of the chromosome. Centromeres can accidentally shrink during division and still function, although it is thought this will fail if it shrinks below a few hundred kilobase. Kinetochores contain RNA originating from centromeres. Centromere regions can become inactive, and can continue in that state if the chromosome still has another active one.
The Maize Genetics Cooperation Stock Center, funded by the USDA Agricultural Research Service and located in the Department of Crop Sciences at the University of Illinois at Urbana-Champaign, is a stock center of maize mutants. The total collection has nearly 80,000 samples. The bulk of the collection consists of several hundred named genes, plus additional gene combinations and other heritable variants. There are about 1000 chromosomal aberrations (e.g., translocations and inversions) and stocks with abnormal chromosome numbers (e.g., tetraploids). Genetic data describing the maize mutant stocks as well as myriad other data about maize genetics can be accessed at MaizeGDB, the Maize Genetics and Genomics Database.
In 2005, the US National Science Foundation (NSF), Department of Agriculture (USDA) and the Department of Energy (DOE) formed a consortium to sequence the B73 maize genome. The resulting DNA sequence data was deposited immediately into GenBank, a public repository for genome-sequence data. Sequences and genome annotations have also been made available throughout the project's lifetime at the project's official site.
Primary sequencing of the maize genome was completed in 2008. On November 20, 2009, the consortium published results of its sequencing effort in Science. The genome, 85% of which is composed of transposons, was found to contain 32,540 genes (By comparison, the human genome contains about 2.9 billion bases and 26,000 genes). Much of the maize genome has been duplicated and reshuffled by helitrons—group of rolling circle transposons.
In Z. mays and various other angiosperms the MADS-box motif is involved in floral development. Early study in several angiosperm models including Z. mays was the beginning of research into the molecular evolution of floral structure in general, as well as their role in nonflowering plants.
EVOLUTION
As with many plants and animals, Z. mays has a positive correlation between effective population size and the magnitude of selection pressure. Z. m. having an EPS of ~650,000, it clusters with others of about the same EPS, and has 79% of its amino acid sites under selection.
Recombination is a significant source of diversity in Z. mays. (Note that this finding supersedes previous studies which showed no such correlation.)
This recombination/diversity effect is seen throughout plants but is also found to not occur – or not as strongly – in regions of high gene density. This is likely the reason that domesticated Z. mays has not seen as much of an increase in diversity within areas of higher density as in regions of lower density, although there is more evidence in other plants.
Some lines of maize have undergone ancient polyploidy events, starting 11m years ago. Over that time ~72% of polyploid duplicated genes have been retained, which is higher than other plants with older polyploidy events. Thus maize may be due to lose more duplicate genes as time goes along, similar to the course followed by the genomes of other plants. If so - if gene loss has merely not occurred yet - that could explain the lack of observed positive selection and lower negative selection which are observed in otherwise similar plants, i.e. also naturally outcrossing and with similar effective population sizes.
Ploidy does not appear to influence EPS or magnitude of selection effect in maize.
BREEDING
Maize reproduces sexually each year. This randomly selects half the genes from a given plant to propagate to the next generation, meaning that desirable traits found in the crop (like high yield or good nutrition) can be lost in subsequent generations unless certain techniques are used.
Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of the earliest and most successful developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection. Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and the highly successful double cross hybrids using four inbred lines (D. F. Jones c. 1918, 1922). University supported breeding programs were especially important in developing and introducing modern hybrids. By the 1930s, companies such as Pioneer devoted to production of hybrid maize had begun to influence long-term development. Internationally important seed banks such as the International Maize and Wheat Improvement Center (CIMMYT) and the US bank at the Maize Genetics Cooperation Stock Center University of Illinois at Urbana-Champaign maintain germplasm important for future crop development.
Since the 1940s the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic modification have succeeded in increasing output and reducing the need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant.
Tropical landraces remain an important and underutilized source of resistance alleles for for disease and for herbivores. Notable discoveries of rare alleles for this purpose were made by Dao et al 2014 and Sood et al 2014.
GLOBAL PROGRAM
CIMMYT operates a conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by the Drought Tolerant Maize for Africa project.
GENETIC MODIFICATION
Genetically modified (GM) maize was one of the 26 GM crops grown commercially in 2016. The vast majority of this is Bt maize. Grown since 1997 in the United States and Canada, 92% of the US maize crop was genetically modified in 2016 and 33% of the worldwide maize crop was GM in 2016. As of 2011, Herbicide-tolerant maize varieties were grown in Argentina, Australia, Brazil, Canada, China, Colombia, El Salvador, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, the Russian Federation, Singapore, South Africa, Taiwan, Thailand, and the United States. Insect-resistant maize was grown in Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, South Africa, Switzerland, Taiwan, the United States, and Uruguay.
In September 2000, up to $50 million worth of food products were recalled due to the presence of Starlink genetically modified corn, which had been approved only for animal consumption and had not been approved for human consumption, and was subsequently withdrawn from the market.
ORIGIN
Maize is the domesticated variant of teosinte. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between the two is largely controlled by differences in just two genes, called grassy tillers-1 (gt1, A0A317YEZ1) and teosinte branched-1 (tb1, Q93WI2).
Several theories had been proposed about the specific origin of maize in Mesoamerica:
It is a direct domestication of a Mexican annual teosinte, Zea mays ssp. parviglumis, native to the Balsas River valley in south-eastern Mexico, with up to 12% of its genetic material obtained from Zea mays ssp. mexicana through introgression.
It has been derived from hybridization between a small domesticated maize (a slightly changed form of a wild maize) and a teosinte of section Luxuriantes, either Z. luxurians or Z. diploperennis.
It has undergone two or more domestications either of a wild maize or of a teosinte. (The term "teosinte" describes all species and subspecies in the genus Zea, excluding Zea mays ssp. mays.)
It has evolved from a hybridization of Z. diploperennis by Tripsacum dactyloides.
In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum, a related genus. This theory about the origin of maize has been refuted by modern genetic testing, which refutes Mangelsdorf's model and the fourth listed above.
The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931 and the later American Nobel Prize-winner George Beadle in 1932.: 10 It is supported experimentally and by recent studies of the plants' genomes. Teosinte and maize can cross-breed and produce fertile offspring. A number of questions remain concerning the species, among them:
how the immense diversity of the species of sect. Zea originated,
how the tiny archaeological specimens of 3500–2700 BC could have been selected from a teosinte, and
how domestication could have proceeded without leaving remains of teosinte or maize with teosintoid traits earlier than the earliest known until recently, dating from ca. 1100 BC.
The domestication of maize is of particular interest to researchers—archaeologists, geneticists, ethnobotanists, geographers, etc. The process is thought by some to have started 7,500 to 12,000 years ago. Research from the 1950s to 1970s originally focused on the hypothesis that maize domestication occurred in the highlands between the states of Oaxaca and Jalisco, because the oldest archaeological remains of maize known at the time were found there.
Connection with 'parviglumis' subspecies
Genetic studies, published in 2004 by John Doebley, identified Zea mays ssp. parviglumis, native to the Balsas River valley in Mexico's southwestern highlands, and also known as Balsas teosinte, as being the crop wild relative that is genetically most similar to modern maize. This was confirmed by further studies, which refined this hypothesis somewhat. Archaeobotanical studies, published in 2009, point to the middle part of the Balsas River valley as the likely location of early domestication; this river is not very long, so these locations are not very distant. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero.
Doebley was part of the team that first published, in 2002, that maize had been domesticated only once, about 9,000 years ago, and then spread throughout the Americas.
A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley, date back roughly 6,250 years; the oldest ears from caves near Tehuacan, Puebla, 5,450 B.P.
Maize pollen dated to 7,300 B.P. from San Andres, Tabasco, on the Caribbean coast has also been recovered.
As maize was introduced to new cultures, new uses were developed and new varieties selected to better serve in those preparations. Maize was the staple food, or a major staple – along with squash, Andean region potato, quinoa, beans, and amaranth – of most pre-Columbian North American, Mesoamerican, South American, and Caribbean cultures. The Mesoamerican civilization, in particular, was deeply interrelated with maize. Its traditions and rituals involved all aspects of maize cultivation – from the planting to the food preparation. Maize formed the Mesoamerican people's identity.
It is unknown what precipitated its domestication, because the edible portion of the wild variety is too small, and hard to obtain, to be eaten directly, as each kernel is enclosed in a very hard bivalve shell.
In 1939, George Beadle demonstrated that the kernels of teosinte are readily "popped" for human consumption, like modern popcorn. Some have argued it would have taken too many generations of selective breeding to produce large, compressed ears for efficient cultivation. However, studies of the hybrids readily made by intercrossing teosinte and modern maize suggest this objection is not well founded.
SPREADING TO THE NORTH
Around 4,500 ago, maize began to spread to the north; it was first cultivated in what is now the United States at several sites in New Mexico and Arizona, about 4,100 ago.
During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for the new crop.
In 2005, research by the USDA Forest Service suggested that the rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels, which are very sensitive to environmental changes.
CULTIVATION
PLANTING
Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As a plant that uses C4 carbon fixation, maize is a considerably more water-efficient crop than plants that use C3 carbon fixation such as alfalfa and soybeans. Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July", although modern hybrids generally exceed this growth rate. Maize used for silage is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine. Although it is grown mainly in wet, hot climates, it has been said to thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop.
Maize was planted by the Native Americans in hills, in a complex system known to some as the Three Sisters. Maize provided support for beans, and the beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. This method was replaced by single species hill planting where each hill 60–120 cm (2 ft 0 in–3 ft 11 in) apart was planted with three or four seeds, a method still used by home gardeners. A later technique was "checked maize", where hills were placed
1 m (40 in) apart in each direction, allowing cultivators to run through the field in two directions. In more arid lands, this was altered and seeds were planted in the bottom of 10–12 cm (4–4+1⁄2 in) deep furrows to collect water. Modern technique plants maize in rows which allows for cultivation while the plant is young, although the hill technique is still used in the maize fields of some Native American reservations. When maize is planted in rows, it also allows for planting of other crops between these rows to make more efficient use of land space.
In most regions today, maize grown in residential gardens is still often planted manually with a hoe, whereas maize grown commercially is no longer planted manually but rather is planted with a planter. In North America, fields are often planted in a two-crop rotation with a nitrogen-fixing crop, often alfalfa in cooler climates and soybeans in regions with longer summers. Sometimes a third crop, winter wheat, is added to the rotation.
Many of the maize varieties grown in the United States and Canada are hybrids. Often the varieties have been genetically modified to tolerate glyphosate or to provide protection against natural pests. Glyphosate is an herbicide which kills all plants except those with genetic tolerance. This genetic tolerance is very rarely found in nature.
In the midwestern United States, low-till or no-till farming techniques are usually used. In low-till, fields are covered once, maybe twice, with a tillage implement either ahead of crop planting or after the previous harvest. The fields are planted and fertilized. Weeds are controlled through the use of herbicides, and no cultivation tillage is done during the growing season. This technique reduces moisture evaporation from the soil, and thus provides more moisture for the crop. The technologies mentioned in the previous paragraph enable low-till and no-till farming. Weeds compete with the crop for moisture and nutrients, making them undesirable.
HARVESTING
Before the 20th century, all maize harvesting was by manual labour, by grazing, or by some combination of those. Whether the ears were hand-picked and the stover was grazed, or the whole plant was cut, gathered, and shocked, people and livestock did all the work. Between the 1890s and the 1970s, the technology of maize harvesting expanded greatly. Today, all such technologies, from entirely manual harvesting to entirely mechanized, are still in use to some degree, as appropriate to each farm's needs, although the thoroughly mechanized versions predominate, as they offer the lowest unit costs when scaled to large farm operations. For small farms, their unit cost can be too high, as their higher fixed cost cannot be amortized over as many units.[citation needed]
Before World War II, most maize in North America was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover) and corn binders, which are reaper-binders designed specifically for maize (for example, Video on YouTube). The latter produce sheaves that can be shocked. By hand or mechanical picker, the entire ear is harvested, which then requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs, and these whole ears are a sufficient form for some livestock feeding use. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine and store it in bins. The combine with a corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil. The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter the machinery. The combine separates the husk and the cob, keeping only the kernels.
When maize is a silage crop, the entire plant is usually chopped at once with a forage harvester (chopper) and ensiled in silos or polymer wrappers. Ensiling of sheaves cut by a corn binder was formerly common in some regions but has become uncommon. For storing grain in bins, the moisture of the grain must be sufficiently low to avoid spoiling. If the moisture content of the harvested grain is too high, grain dryers are used to reduce the moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases (propane or natural gas) and electricity to power the blowers.
PRODUCTION
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2018, total world production was 1.15 billion tonnes, led by the United States with 34.2% of the total (table). China produced 22.4% of the global total.
UNITED STATES
In 2016, maize production was forecast to be over 380 million metric tons (15 billion bushels), an increase of 11% over 2014 American production. Based on conditions as of August 2016, the expected yield would be the highest ever for the United States. The area of harvested maize was forecast to be 35 million hectares (87 million acres), an increase of 7% over 2015. Maize is especially popular in Midwestern states such as Indiana, Iowa, and Illinois; in the latter, it was named the state's official grain in 2017.
STORAGE
Drying is vital to prevent or at least reduce mycotoxin contamination. Aspergillus and Fusarium spp. are the most common mycotoxin sources, but there are others. Altogether maize contaminants are so common, and this crop is so economically important, that maize mycotoxins are among the most important in agriculture in general.
USES
HUMAN FOOD
Maize and cornmeal (ground dried maize) constitute a staple food in many regions of the world. Maize is used to produce cornstarch, a common ingredient in home cooking and many industrialized food products. Maize starch can be hydrolyzed and enzymatically treated to produce syrups, particularly high fructose corn syrup, a sweetener; and also fermented and distilled to produce grain alcohol. Grain alcohol from maize is traditionally the source of Bourbon whiskey. Corn flour is used to make cornbread and other baked products.
In prehistoric times Mesoamerican women used a metate to process maize into ground cornmeal, allowing the preparation of foods that were more calorie dense than popcorn. After ceramic vessels were invented the Olmec people began to cook maize together with beans, improving the nutritional value of the staple meal. Although maize naturally contains niacin, an important nutrient, it was not bioavailable without the process of nixtamalization. The Maya used nixtamal meal to make varieties of porridges and tamales. The process was later used in the cuisine of the American South to prepare corn for grits and hominy.
Maize is a staple of Mexican cuisine. Masa (cornmeal treated with limewater) is the main ingredient for tortillas, atole and many other dishes of Central American food. It is the main ingredient of corn tortilla, tamales, pozole, atole and all the dishes based on them, like tacos, quesadillas, chilaquiles, enchiladas, tostadas and many more. In Mexico the fungus of maize, known as huitlacoche, is considered a delicacy.
Coarse maize meal is made into a thick porridge in many cultures: from the polenta of Italy, the angu of Brazil, the mămăligă of Romania, to cornmeal mush in the US (or hominy grits in the South) or the food called mieliepap in South Africa and sadza, nshima, ugali and other names in other parts of Africa. Introduced into Africa by the Portuguese in the 16th century, maize has become Africa's most important staple food crop. These are commonly eaten in the Southeastern United States, foods handed down from Native Americans, who called the dish sagamite.
Maize can also be harvested and consumed in the unripe state, when the kernels are fully grown but still soft. Unripe maize must usually be cooked to become palatable; this may be done by simply boiling or roasting the whole ears and eating the kernels right off the cob. Sweet corn, a genetic variety that is high in sugars and low in starch, is usually consumed in the unripe state. Such corn on the cob is a common dish in the United States, Canada, United Kingdom, Cyprus, some parts of South America, and the Balkans, but virtually unheard of in some European countries. Corn on the cob was hawked on the streets of early 19th-century New York City by poor, barefoot "Hot Corn Girls", who were thus the precursors of hot dog carts, churro wagons, and fruit stands seen on the streets of big cities today.
Within the United States, the usage of maize for human consumption constitutes only around 1/40th of the amount grown in the country. In the United States and Canada, maize is mostly grown to feed livestock, as forage, silage (made by fermentation of chopped green cornstalks), or grain. Maize meal is also a significant ingredient of some commercial animal food products.
NUTRITIONAL VALUE
Raw, yellow, sweet maize kernels are composed of 76% water, 19% carbohydrates, 3% protein, and 1% fat (table). In a 100-gram serving, maize kernels provide 86 calories and are a good source (10–19% of the Daily Value) of the B vitamins, thiamin, niacin (but see Pellagra warning below), pantothenic acid (B5) and folate (right table for raw, uncooked kernels, USDA Nutrient Database). In moderate amounts, they also supply dietary fiber and the essential minerals, magnesium and phosphorus whereas other nutrients are in low amounts (table).
Maize has suboptimal amounts of the essential amino acids tryptophan and lysine, which accounts for its lower status as a protein source. However, the proteins of beans and legumes complement those of maize.
FEED AND FODDER FOR LIVESTOCK
Maize is a major source of both grain feed and fodder for livestock. It is fed to the livestock in various ways. When it is used as a grain crop, the dried kernels are used as feed. They are often kept on the cob for storage in a corn crib, or they may be shelled off for storage in a grain bin. The farm that consumes the feed may produce it, purchase it on the market, or some of both. When the grain is used for feed, the rest of the plant (the corn stover) can be used later as fodder, bedding (litter), or soil amendment. When the whole maize plant (grain plus stalks and leaves) is used for fodder, it is usually chopped all at once and ensilaged, as digestibility and palatability are higher in the ensilaged form than in the dried form. Maize silage is one of the most valuable forages for ruminants. Before the advent of widespread ensilaging, it was traditional to gather the corn into shocks after harvesting, where it dried further. With or without a subsequent move to the cover of a barn, it was then stored for weeks to several months until fed to the livestock. Today ensilaging can occur not only in siloes but also in silage wrappers. However, in the tropics, maize can be harvested year-round and fed as green forage to the animals.
CHEMICALS
Starch from maize can also be made into plastics, fabrics, adhesives, and many other chemical products.
The corn steep liquor, a plentiful watery byproduct of maize wet milling process, is widely used in the biochemical industry and research as a culture medium to grow many kinds of microorganisms.
Chrysanthemin is found in purple corn and is used as a food coloring.
BIO-FUEL
"Feed maize" is being used increasingly for heating; specialized corn stoves (similar to wood stoves) are available and use either feed maize or wood pellets to generate heat. Maize cobs are also used as a biomass fuel source. Maize is relatively cheap and home-heating furnaces have been developed which use maize kernels as a fuel. They feature a large hopper that feeds the uniformly sized maize kernels (or wood pellets or cherry pits) into the fire.[citation needed]
Maize is increasingly used as a feedstock for the production of ethanol fuel. When considering where to construct an ethanol plant, one of the site selection criteria is to ensure there is locally available feedstock. Ethanol is mixed with gasoline to decrease the amount of pollutants emitted when used to fuel motor vehicles. High fuel prices in mid-2007 led to higher demand for ethanol, which in turn led to higher prices paid to farmers for maize. This led to the 2007 harvest being one of the most profitable maize crops in modern history for farmers. Because of the relationship between fuel and maize, prices paid for the crop now tend to track the price of oil.
The price of food is affected to a certain degree by the use of maize for biofuel production. The cost of transportation, production, and marketing are a large portion (80%) of the price of food in the United States. Higher energy costs affect these costs, especially transportation. The increase in food prices the consumer has been seeing is mainly due to the higher energy cost. The effect of biofuel production on other food crop prices is indirect. Use of maize for biofuel production increases the demand, and therefore price of maize. This, in turn, results in farm acreage being diverted from other food crops to maize production. This reduces the supply of the other food crops and increases their prices.
Maize is widely used in Germany as a feedstock for biogas plants. Here the maize is harvested, shredded then placed in silage clamps from which it is fed into the biogas plants. This process makes use of the whole plant rather than simply using the kernels as in the production of fuel ethanol.
A biomass gasification power plant in Strem near Güssing, Burgenland, Austria, began in 2005. Research is being done to make diesel out of the biogas by the Fischer Tropsch method.
Increasingly, ethanol is being used at low concentrations (10% or less) as an additive in gasoline (gasohol) for motor fuels to increase the octane rating, lower pollutants, and reduce petroleum use (what is nowadays also known as "biofuels" and has been generating an intense debate regarding the human beings' necessity of new sources of energy, on the one hand, and the need to maintain, in regions such as Latin America, the food habits and culture which has been the essence of civilizations such as the one originated in Mesoamerica; the entry, January 2008, of maize among the commercial agreements of NAFTA has increased this debate, considering the bad labor conditions of workers in the fields, and mainly the fact that NAFTA "opened the doors to the import of maize from the United States, where the farmers who grow it receive multimillion-dollar subsidies and other government supports. ... According to OXFAM UK, after NAFTA went into effect, the price of maize in Mexico fell 70% between 1994 and 2001. The number of farm jobs dropped as well: from 8.1 million in 1993 to 6.8 million in 2002. Many of those who found themselves without work were small-scale maize growers."). However, introduction in the northern latitudes of the US of tropical maize for biofuels, and not for human or animal consumption, may potentially alleviate this.
COMMODITY
Maize is bought and sold by investors and price speculators as a tradable commodity using corn futures contracts. These "futures" are traded on the Chicago Board of Trade (CBOT) under ticker symbol C. They are delivered every year in March, May, July, September, and December.
ORNAMENTAL AND OTHER USES
Some forms of the plant are occasionally grown for ornamental use in the garden. For this purpose, variegated and colored leaf forms as well as those with colorful ears are used.
Corncobs can be hollowed out and treated to make inexpensive smoking pipes, first manufactured in the United States in 1869.
An unusual use for maize is to create a "corn maze" (or "maize maze") as a tourist attraction. The idea of a maize maze was introduced by the American Maze Company who created a maze in Pennsylvania in 1993. Traditional mazes are most commonly grown using yew hedges, but these take several years to mature. The rapid growth of a field of maize allows a maze to be laid out using GPS at the start of a growing season and for the maize to grow tall enough to obstruct a visitor's line of sight by the start of the summer. In Canada and the US, these are popular in many farming communities.
Maize kernels can be used in place of sand in a sandboxlike enclosure for children's play.
Stigmas from female maize flowers, popularly called corn silk, are sold as herbal supplements.
Maize is used as a fish bait, called "dough balls". It is particularly popular in Europe for coarse fishing.
Additionally, feed corn is sometimes used by hunters to bait animals such as deer or wild hogs.
UNITED STATES USAGE BREAKDOWN
The breakdown of usage of the 12.1-billion-bushel (307-million-tonne) 2008 US maize crop was as follows, according to the World Agricultural Supply and Demand Estimates Report by the USDA.In the US since 2009/2010, maize feedstock use for ethanol production has somewhat exceeded direct use for livestock feed; maize use for fuel ethanol was 5,130 million bushels (130 million tonnes) in the 2013/2014 marketing year.A fraction of the maize feedstock dry matter used for ethanol production is usefully recovered as DDGS (dried distillers grains with solubles). In the 2010/2011 marketing year, about 29.1 million tonnes of DDGS were fed to US livestock and poultry. Because starch utilization in fermentation for ethanol production leaves other grain constituents more concentrated in the residue, the feed value per kg of DDGS, with regard to ruminant-metabolizable energy and protein, exceeds that of the grain. Feed value for monogastric animals, such as swine and poultry, is somewhat lower than for ruminants.
HAZARDS
PELLAGRA
When maize was first introduced into farming systems other than those used by traditional native-American peoples, it was generally welcomed with enthusiasm for its productivity. However, a widespread problem of malnutrition soon arose wherever maize was introduced as a staple food. This was a mystery, since these types of malnutrition were not normally seen among the indigenous Americans, for whom maize was the principal staple food.
It was eventually discovered that the indigenous Americans had learned to soak maize in alkali — water (the process now known as nixtamalization) — made with ashes and lime (calcium oxide) since at least 1200–1500 BC by Mesoamericans. They did this to liberate the corn hulls, but (unbeknownst to natives or colonists) it coincidentally liberates the B-vitamin niacin, the lack of which was the underlying cause of the condition known as pellagra.
Maize was introduced into the diet of non-indigenous Americans without the necessary cultural knowledge acquired over thousands of years in the Americas. In the late 19th century, pellagra reached epidemic proportions in parts of the southern US, as medical researchers debated two theories for its origin: the deficiency theory (which was eventually shown to be true) said that pellagra was due to a deficiency of some nutrient, and the germ theory said that pellagra was caused by a germ transmitted by stable flies. A third theory, promoted by the eugenicist Charles Davenport, held that people only contracted pellagra if they were susceptible to it due to certain "constitutional, inheritable" traits of the affected individual.
Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high lysine maize and the promotion of a more balanced diet have also contributed to its demise. Pellagra still exists today in food-poor areas and refugee camps where people survive on donated maize.
ALLERGY
Maize contains lipid transfer protein, an indigestible protein that survives cooking. This protein has been linked to a rare and understudied allergy to maize in humans. The allergic reaction can cause skin rash, swelling or itching of mucous membranes, diarrhea, vomiting, asthma and, in severe cases, anaphylaxis. It is unclear how common this allergy is in the general population.
MYCOTOXINS
Fungicide application does not reduce fungal growth or mycotoxin dramatically, although it can be a part of a successful reduction strategy. Among the most common toxins are those produced by Aspergillus and Fusarium spp. The most common toxins are aflatoxins, fumonisins, zearalenone, and ochratoxin A. Bt maize discourages insect vectors and by so doing it dramatically reduces concentrations of fumonisins, significantly reduces aflatoxins, but only mildly reduces others.
ART
Maize has been an essential crop in the Andes since the pre-Columbian era. The Moche culture from Northern Peru made ceramics from earth, water, and fire. This pottery was a sacred substance, formed in significant shapes and used to represent important themes. Maize was represented anthropomorphically as well as naturally.
In the United States, maize ears along with tobacco leaves are carved into the capitals of columns in the United States Capitol building. Maize itself is sometimes used for temporary architectural detailing when the intent is to celebrate the fall season, local agricultural productivity and culture. Bundles of dried maize stalks are often displayed along with pumpkins, gourds and straw in autumnal displays outside homes and businesses. A well-known example of architectural use is the Corn Palace in Mitchell, South Dakota, which uses cobs and ears of colored maize to implement a mural design that is recycled annually. Another well-known example is the Field of Corn sculpture in Dublin, Ohio, where hundreds of concrete ears of corn stand in a grassy field.
A maize stalk with two ripe ears is depicted on the reverse of the Croatian 1 lipa coin, minted since 1993.

This morning the Triumph arrived in the port of Rotterdam with the oil rig Maesrk Resolve on deck. The Triumph is a heavy transport ship from the dutch company Dockwise.
The semi-submersible heavy lift vessel Triumph now joins the fleet of Dockwise. The Triumph is one of six single-hull tankers converted into heavy lift vessels at the Cosco Guangdong Shipyard. The vessel was delivered on December 16, 2008 and left for Singapore to load its first cargo on December 17, 2008.
The heavy transport vessel is designed to transport complex, high-value cargo and has a carrying capacity in excess of 35,000 tons. With an unobstructed deck area measuring 44.5 m x 130 m, the vessel is well suited for carrying semi-submersible and jack-up drilling units, as well as offshore structures. During the conversion, the entire midsection was newly constructed and fitted to the bow and aft part of the single-hull tanker. As a result, the classification authorities consider the vessel to have an economic life of around ten years, resulting in a remaining economic life of 20 years.
To ensure the most effective way of operating the vessel, Dockwise has appointed Anglo-Eastern Ship Management to provide technical and crew management. As such, the new vessels will operate under the same management systems as the existing Dockwise vessels. Crews, superintendents and other personnel will therefore be completely familiar with all operating procedures, ensuring safe operations.

This unique Great Lakes self-unloading bulk carrier was built by Port Weller Dry Docks, St. Catharines, Ont., as Hull #41. She was christened Canadian Century for Upper Lakes Group, Inc., Toronto, Ont., on April 15, 1967 by Mrs. G. E. Gathercole, wife of the Chairman of the Hydro Electric Power Commission of Ontario. The name paid tribute to the 100th anniversary of Canada’s confederation.
At the time of her launch, the vessel was the largest capacity self-unloading vessel on the Great Lakes. Her squared hull design reduced wasted space thus increasing her tonnage, however her very tall wheelhouse and forward accommodation block gave her the distinction of being known as the “little bank building that floats.”
The Canadian Century’s original self-unloading system consisted of a single, center line conveyor belt gravity system with a 300-ton reclaimer feeding a bucket/hopper elevator system leading to a forward-mounted 250 foot discharge boom. The reclaimer consisted of 2 auger screws, each 26 feet long and 7 feet high. As they would turn, the cargo would be forced forward to the bucket elevator system. It could discharge at a rate of up to 4,000 tons per hour. Due to the technological advances in self-unloading systems, the Canadian Century’s bucket elevator system was replaced in 1975/76 with a modern loop belt elevator system capable of discharging cargo at a rate of up to 4,572 tons per hour. The discharge boom can be swung 95 degrees to port or starboard.
The vessel is powered by a Burmeister & Wain type 574 VT2F 160 diesel engine rated at 7,394 b.h.p. at 115 r.p.m. burning intermediate grade 180 fuel driving a controllable pitch propeller, giving the vessel a service speed of 14.5 knots. She is equipped with a 1,000 horsepower bowthruster. Her enormous single hold is fed by 22 hatches. She can carry 25,700 tons at maximum Seaway draft of 26 feet and is capable of carrying 31,600 tons at her maximum mid-summer draft of 29 feet 4 inches. Other capacities include 465 tons of fuel oil, 75 tons of diesel oil, 186 tons of potable water, and 17,348 tons of water ballast.
In December 2001, Canadian Century entered Port Weller Dry Docks for a mid-life refit. The $25-million (C) refit was similar to the work that the shipyard completed on Canada Steamship Lines’ CSL Tadoussac the winter before. The bow and stern sections remained intact, along with most of the main deck. The cargo hold and the rest of the midsection were replaced with a new, larger cargo hold and a one-belt self-unloading system with a flat tank top. When it returned to service in May of 2002, it not only carried more cargo, but could operate more efficiently through the increased use of technology.
The Century was built specifically to accommodate Upper Lakes Group’s first contract to carry coal for Ontario Hydro. During her first season of operation, she made 63 trips delivering coal totaling 1.7 million tons. On Dec. 8, 1967, she set a Welland Canal coal record by carrying 28,283 tons from Conneaut, Ohio, to Dofasco at Hamilton, Ont. June 18, 1969 saw the Canadian Century load a Conneaut, Ohio, record of 31,081 tons of coal for Ontario Hydro’s Lambton Generating Station at Courtright, Ont. In her early years, she would sail to Sept Isles, Que., to rendezvous with her former fleet mate Ontario Power to transfer coal loaded aboard the latter vessel at Sydney, Nova Scotia, for delivery to Nanticoke, Ont. The Canadian Century carried her first load of taconite ore pellets in 1986 when she loaded 25,427 tons at Pointe Noire, Que., for Hamilton, Ont. The vessel has carried cargoes of salt from ports such as Goderich, Ont., and Fairport, Ohio. She has also carried the odd cargo of grain products.
In her later years, the Canadian Century sailed under the management of Seaway Marine Transport, St. Catharines, Ont., a partnership of Algoma Central and Upper Lakes Group.
On March 23, 2001, the vessel was honored in the traditional Top Hat ceremony recognizing the passing of the first upbound vessel through the Welland Canal for the 2001 navigation season.
In 2002, the vessel was renamed John D. Leitch, honoring the chairman of the Upper Lakes Group. On February 25, 2011, a formal statement was issued announcing the sale of the privately owned Upper Lakes fleet and their associated interest in Seaway Marine Transport to the Algoma Central Corporation. On April 15, 2011, Algoma announced that the John D. Leitch would retain her name.

The SS 'Richard Montgomery' was built by the St. Johns River Shipbuilding Company in its second year of operations, and was the seventh of the 82 such ships built by that yard. Laid down on 15 March 1943, she was launched on 15 June 1943, and completed on 29 July 1943, given the official ship number 243756, and named after General Richard Montgomery, an Irish-American soldier who was killed during the American Revolutionary War.
In August 1944, on what was to be its final voyage, the ship left Hog Island, Philadelphia, where it had been loaded with 6,127 tons of munitions.
It travelled from the Delaware river to the Thames Estuary, then anchored while awaiting the formation of a convoy to travel to Cherbourg, France, which had come under Allied control on 27 July 1944 during the Battle of Normandy.
When Richard Montgomery arrived off Southend, it came under the authority of the Thames naval control at HMS Leigh located at the end of Southend Pier. The harbour master, responsible for all shipping movements in the estuary, ordered the ship to a berth off the north edge of Sheerness middle sands, an area designated as the Great Nore Anchorage.
On 20 August 1944, it dragged anchor and ran aground on a sandbank around 250 metres from the Medway Approach Channel,[5] in a depth of 24 feet (7.3 m) of water. The general dry cargo liberty ship had an average draught of 28 ft (8.5 m); however, the Montgomery was trimmed to a draught of 31 ft (9.4 m). As the tide went down, the ship broke its back on sand banks near the Isle of Sheppey about 1.5 miles (2.5 km) from Sheerness and 5 miles (8 km) from Southend.
A Rochester-based stevedore company was given the job of removing the cargo, which began on 23 August 1944, using the ship's own cargo handling equipment. By the next day, the ship's hull had cracked open, causing several cargo holds at the bow end to flood. The salvage operation continued until 25 September, when the ship was finally abandoned before all the cargo had been recovered. Subsequently, the ship broke into two separate parts, roughly at the midsection.
During the inquiry following the shipwreck it was revealed that several ships moored nearby had noticed the Montgomery drifting towards the sandbank. They had attempted to signal an alert by sounding their sirens without avail, since throughout this Captain Wilkie of the Montgomery was asleep. The ship's chief officer was unable to explain why he had not alerted the captain. A Board of Inquiry concluded that the anchorage the harbour master assigned had placed the ship in jeopardy, and returned the Montgomery's captain to full duty within a week.
SS Richard Montgomery was an American Liberty ship built during World War II, one of the 2,710 used to carry cargo during the war. The ship was wrecked off the Nore in the Thames Estuary in 1944 with around 1,400 tonnes (1,500 short tons) of explosives on board which continue to be a hazard to the area.
Mulberry harbours were temporary portable harbours developed by the British during World War II to facilitate the rapid offloading of cargo onto beaches during the Allied invasion of Normandy in June 1944. After the Allies successfully held beachheads following D-Day, two prefabricated harbours were taken in sections across the English Channel from Britain with the invading army and assembled off Omaha (Mulberry "A") and Gold Beach (Mulberry "B").
The Mulberry harbours were to be used until the Allies could capture a French port; initially thought to be around three months. However although Antwerp in Belgium was captured on 4 September 1944, the Port of Antwerp was not opened until 28 November as the approaches to the port were held by the Germans until the (delayed) Battle of the Scheldt was won. Two French ports were eventually available; the port of Boulogne on 14 October after Operation Wellhit and the port of Calais in November after Operation Undergo. Montgomery insisted that the First Canadian Army clear the German garrisons in Boulogne, Calais and Dunkirk (which was held until 9 May 1945) first before the Scheldt although the French ports were "resolutely defended" and had all suffered demolitions so would not be navigable for some time. The success of Operation Dragoon meant that the southern French ports of Marseille and Toulon were available in October.
So the need for the harbour at Gold Beach lessened only about five months after D-Day. It was used for 10 months after D-Day; and over 2.5 million men, 500,000 vehicles, and 4 million tonnes of supplies were landed at Gold Beach before it was fully decommissioned. The Mulberry harbour at Omaha Beach had been severely damaged in a storm in late June 1944 and was abandoned. This one, off Shoeburyness, was damaged whilst being towed to France, and abandoned at it's current site.
Maize (/meɪz/ MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taino: mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits.
Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and corn syrup. The six major types of maize are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn. Sugar-rich varieties called sweet corn are usually grown for human consumption as kernels, while field corn varieties are used for animal feed, various corn-based human food uses (including grinding into cornmeal or masa, pressing into corn oil, and fermentation and distillation into alcoholic beverages like bourbon whiskey), and as chemical feedstocks. Maize is also used in making ethanol and other biofuels.
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2014, total world production was 1.04 billion tonnes. Maize is the most widely grown grain crop throughout the Americas, with 361 million metric tons grown in the United States alone in 2014. Genetically modified maize made up 85% of the maize planted in the United States in 2009. Subsidies in the United States help to account for its high level of cultivation of maize and its position as the largest producer in the world.
HISTORY
PRE-COLUMBIAN DEVELOPMENT
Maize is a cultigen; human intervention is required for it to propagate. Whether or not the kernels fall off the cob on their own is a key piece of evidence used in archaeology to distinguish domesticated maize from its naturally-propagating teosinte ancestor. Genetic evidence can also be used to determine when various lineages split.
Most historians believe maize was domesticated in the Tehuacán Valley of Mexico. Recent research in the early 21st century has modified this view somewhat; scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication.
An influential 2002 study by Matsuoka et al. has demonstrated that, rather than the multiple independent domestications model, all maize arose from a single domestication in southern Mexico about 9,000 years ago. The study also demonstrated that the oldest surviving maize types are those of the Mexican highlands. Later, maize spread from this region over the Americas along two major paths. This is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands.
Archaeologist Dolores Piperno has said:
A large corpus of data indicates that [maize] was dispersed into lower Central America by 7600 BP [5600 BC] and had moved into the inter-Andean valleys of Colombia between 7000 and 6000 BP [5000–4000 BC].
— Dolores Piperno, The Origins of Plant Cultivation and Domestication in the New World Tropics: Patterns, Process, and New Developments
Since then, even earlier dates have been published.
According to a genetic study by Embrapa, corn cultivation was introduced in South America from Mexico, in two great waves: the first, more than 6000 years ago, spread through the Andes. Evidence of cultivation in Peru has been found dating to about 6700 years ago. The second wave, about 2000 years ago, through the lowlands of South America.
The earliest maize plants grew only small, 25-millimetre-long (1 in) corn cobs, and only one per plant. In Jackson Spielvogel's view, many centuries of artificial selection (rather than the current view that maize was exploited by interplanting with teosinte) by the indigenous people of the Americas resulted in the development of maize plants capable of growing several cobs per plant, which were usually several centimetres/inches long each. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica; they cooked, ground and processed it through nixtamalization. It was believed that beginning about 2500 BC, the crop spread through much of the Americas. Research of the 21st century has established even earlier dates. The region developed a trade network based on surplus and varieties of maize crops.
Mapuches of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times; however, potato was the staple food of most Mapuches, "specially in the southern and coastal [Mapuche] territories where maize did not reach maturity". Before the expansion of the Inca Empire maize was traded and transported as far south as 40°19' S in Melinquina, Lácar Department. In that location maize remains were found inside pottery dated to 730 ± 80 BP and 920 ± 60 BP. Probably this maize was brought across the Andes from Chile. The presence of maize in Guaitecas Archipelago (43°55' S), the southernmost outpost of pre-Hispanic agriculture, is reported by early Spanish explorers. However the Spanish may have misidentified the plant.
COLUMBIAN EXCHANGE
After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe and introduced it to other countries. Spanish settlers far preferred wheat bread to maize, cassava, or potatoes. Maize flour could not be substituted for wheat for communion bread, since in Christian belief only wheat could undergo transubstantiation and be transformed into the body of Christ. Some Spaniards worried that by eating indigenous foods, which they did not consider nutritious, they would weaken and risk turning into Indians. "In the view of Europeans, it was the food they ate, even more than the environment in which they lived, that gave Amerindians and Spaniards both their distinctive physical characteristics and their characteristic personalities." Despite these worries, Spaniards did consume maize. Archeological evidence from Florida sites indicate they cultivated it as well.
Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. Widespread cultivation most likely began in southern Spain in 1525, after which it quickly spread to the rest of the Spanish Empire including its territories in Italy (and, from there, to other Italian states). Maize had many advantages over wheat and barley; it yielded two and a half times the food energy per unit cultivated area, could be harvested in successive years from the same plot of land, and grew in wildly varying altitudes and climates, from relatively dry regions with only 250 mm (10 in) of annual rainfall to damp regions with over 5,000 mm (200 in). By the 17th century it was a common peasant food in Southwestern Europe, including Portugal, Spain, southern France, and Italy. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially in the form of polenta in Italy.
Names
The word maize derives from the Spanish form of the indigenous Taíno word for the plant, mahiz. It is known by other names around the world.
The word "corn" outside the US, Canada, Australia, and New Zealand refers to any cereal crop, its meaning understood to vary geographically to refer to the local staple. In the United States, Canada, Australia, and New Zealand, corn primarily means maize; this usage started as a shortening of "Indian corn". "Indian corn" primarily means maize (the staple grain of indigenous Americans), but can refer more specifically to multicolored "flint corn" used for decoration.
In places outside the US, Canada, Australia, and New Zealand, corn often refers to maize in culinary contexts. The narrower meaning is usually indicated by some additional word, as in sweet corn, sweetcorn, corn on the cob, baby corn, the puffed confection known as popcorn and the breakfast cereal known as corn flakes.
In Southern Africa, maize is commonly called mielie (Afrikaans) or mealie (English), words derived from the Portuguese word for maize, milho.
Maize is preferred in formal, scientific, and international usage because it refers specifically to this one grain, unlike corn, which has a complex variety of meanings that vary by context and geographic region. Maize is used by agricultural bodies and research institutes such as the FAO and CSIRO. National agricultural and industry associations often include the word maize in their name even in English-speaking countries where the local, informal word is something other than maize; for example, the Maize Association of Australia, the Indian Maize Development Association, the Kenya Maize Consortium and Maize Breeders Network, the National Maize Association of Nigeria, the Zimbabwe Seed Maize Association.
STRUCTURE AND PHYSIOLOGY
The maize plant is often 3 m (10 ft) in height, though some natural strains can grow 13 m (43 ft). The stem is commonly composed of 20 internodes of 18 cm (7 in) length. The leaves arise from the nodes, alternately on opposite sides on the stalk. A leaf, which grows from each node, is generally 9 cm (3+1⁄2 in) in width and 120 cm (3 ft 11 in) in length.
Ears develop above a few of the leaves in the midsection of the plant, between the stem and leaf sheath, elongating by around 3 mm (1⁄8 in) per day, to a length of 18 cm (7 in) with 60 cm (24 in) being the maximum alleged in the subspecies. They are female inflorescences, tightly enveloped by several layers of ear leaves commonly called husks. Certain varieties of maize have been bred to produce many additional developed ears. These are the source of the "baby corn" used as a vegetable in Asian cuisine.
The apex of the stem ends in the tassel, an inflorescence of male flowers. When the tassel is mature and conditions are suitably warm and dry, anthers on the tassel dehisce and release pollen. Maize pollen is anemophilous (dispersed by wind), and because of its large settling velocity, most pollen falls within a few meters of the tassel.
Elongated stigmas, called silks, emerge from the whorl of husk leaves at the end of the ear. They are often pale yellow and 18 cm (7 in) in length, like tufts of hair in appearance. At the end of each is a carpel, which may develop into a "kernel" if fertilized by a pollen grain. The pericarp of the fruit is fused with the seed coat referred to as "caryopsis", typical of the grasses, and the entire kernel is often referred to as the "seed". The cob is close to a multiple fruit in structure, except that the individual fruits (the kernels) never fuse into a single mass. The grains are about the size of peas, and adhere in regular rows around a white, pithy substance, which forms the ear. The maximum size of kernels is reputedly 2.5 cm (1 in). An ear commonly holds 600 kernels. They are of various colors: blackish, bluish-gray, purple, green, red, white and yellow. When ground into flour, maize yields more flour with much less bran than wheat does. It lacks the protein gluten of wheat and, therefore, makes baked goods with poor rising capability. A genetic variant that accumulates more sugar and less starch in the ear is consumed as a vegetable and is called sweet corn. Young ears can be consumed raw, with the cob and silk, but as the plant matures (usually during the summer months), the cob becomes tougher and the silk dries to inedibility. By the end of the growing season, the kernels dry out and become difficult to chew without cooking them tender first in boiling water.
Planting density affects multiple aspects of maize. Modern farming techniques in developed countries usually rely on dense planting, which produces one ear per stalk. Stands of silage maize are yet denser,[citation needed] and achieve a lower percentage of ears and more plant matter.
Maize is a facultative short-day plant and flowers in a certain number of growing degree days > 10 °C (50 °F) in the environment to which it is adapted. The magnitude of the influence that long nights have on the number of days that must pass before maize flowers is genetically prescribed and regulated by the phytochrome system.
Photoperiodicity can be eccentric in tropical cultivars such that the long days characteristic of higher latitudes allow the plants to grow so tall that they do not have enough time to produce seed before being killed by frost. These attributes, however, may prove useful in using tropical maize for biofuels.
Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). DIMBOA is a member of a group of hydroxamic acids (also known as benzoxazinoids) that serve as a natural defense against a wide range of pests, including insects, pathogenic fungi and bacteria. DIMBOA is also found in related grasses, particularly wheat. A maize mutant (bx) lacking DIMBOA is highly susceptible to attack by aphids and fungi. DIMBOA is also responsible for the relative resistance of immature maize to the European corn borer (family Crambidae). As maize matures, DIMBOA levels and resistance to the corn borer decline.
Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to be uprooted by severe winds.
While yellow maizes derive their color from lutein and zeaxanthin, in red-colored maizes, the kernel coloration is due to anthocyanins and phlobaphenes. These latter substances are synthesized in the flavonoids synthetic pathway from polymerization of flavan-4-ols by the expression of maize pericarp color1 (p1) gene which encodes an R2R3 myb-like transcriptional activator of the A1 gene encoding for the dihydroflavonol 4-reductase (reducing dihydroflavonols into flavan-4-ols) while another gene (Suppressor of Pericarp Pigmentation 1 or SPP1) acts as a suppressor. The p1 gene encodes an Myb-homologous transcriptional activator of genes required for biosynthesis of red phlobaphene pigments, while the P1-wr allele specifies colorless kernel pericarp and red cobs, and unstable factor for orange1 (Ufo1) modifies P1-wr expression to confer pigmentation in kernel pericarp, as well as vegetative tissues, which normally do not accumulate significant amounts of phlobaphene pigments. The maize P gene encodes a Myb homolog that recognizes the sequence CCT/AACC, in sharp contrast with the C/TAACGG bound by vertebrate Myb proteins.
The ear leaf is the leaf most closely associated with a particular developing ear. This leaf and above contribute 70% to 75% to 90% of grain fill. Therefore fungicide application is most important in that region in most disease environments.
ABNORMAL FLOWERS
Maize flowers may sometimes exhibit mutations that lead to the formation of female flowers in the tassel. These mutations, ts4 and Ts6, prohibit the development of the stamen while simultaneously promoting pistil development. This may cause inflorescences containing both male and female flowers, or hermaphrodite flowers.
GENETICS
Maize is an annual grass in the family Gramineae, which includes such plants as wheat, rye, barley, rice, sorghum, and sugarcane. There are two major species of the genus Zea (out of six total): Zea mays (maize) and Zea diploperennis, which is a perennial type of teosinte. The annual teosinte variety called Zea mays mexicana is the closest botanical relative to maize. It still grows in the wild as an annual in Mexico and Guatemala.
Many forms of maize are used for food, sometimes classified as various subspecies related to the amount of starch each has:
Flour corn: Zea mays var. amylacea
Popcorn: Zea mays var. everta
Dent corn : Zea mays var. indentata
Flint corn: Zea mays var. indurata
Sweet corn: Zea mays var. saccharata and Zea mays var. rugosa
Waxy corn: Zea mays var. ceratina
Amylomaize: Zea mays
Pod corn: Zea mays var. tunicata Larrañaga ex A. St. Hil.
Striped maize: Zea mays var. japonica
This system has been replaced (though not entirely displaced) over the last 60 years by multivariable classifications based on ever more data. Agronomic data were supplemented by botanical traits for a robust initial classification, then genetic, cytological, protein and DNA evidence was added. Now, the categories are forms (little used), races, racial complexes, and recently branches.
Maize is a diploid with 20 chromosomes (n=10). The combined length of the chromosomes is 1500 cM. Some of the maize chromosomes have what are known as "chromosomal knobs": highly repetitive heterochromatic domains that stain darkly. Individual knobs are polymorphic among strains of both maize and teosinte.
Barbara McClintock used these knob markers to validate her transposon theory of "jumping genes", for which she won the 1983 Nobel Prize in Physiology or Medicine. Maize is still an important model organism for genetics and developmental biology today.
The centromeres have two types of structural components, both of which are found only in the centromeres: Large arrays of CentC, a short satellite DNA; and a few of a family of retrotransposons. The B chromosome, unlike the others, contains an additional repeat which extends into neighboring areas of the chromosome. Centromeres can accidentally shrink during division and still function, although it is thought this will fail if it shrinks below a few hundred kilobase. Kinetochores contain RNA originating from centromeres. Centromere regions can become inactive, and can continue in that state if the chromosome still has another active one.
The Maize Genetics Cooperation Stock Center, funded by the USDA Agricultural Research Service and located in the Department of Crop Sciences at the University of Illinois at Urbana-Champaign, is a stock center of maize mutants. The total collection has nearly 80,000 samples. The bulk of the collection consists of several hundred named genes, plus additional gene combinations and other heritable variants. There are about 1000 chromosomal aberrations (e.g., translocations and inversions) and stocks with abnormal chromosome numbers (e.g., tetraploids). Genetic data describing the maize mutant stocks as well as myriad other data about maize genetics can be accessed at MaizeGDB, the Maize Genetics and Genomics Database.
In 2005, the US National Science Foundation (NSF), Department of Agriculture (USDA) and the Department of Energy (DOE) formed a consortium to sequence the B73 maize genome. The resulting DNA sequence data was deposited immediately into GenBank, a public repository for genome-sequence data. Sequences and genome annotations have also been made available throughout the project's lifetime at the project's official site.
Primary sequencing of the maize genome was completed in 2008. On November 20, 2009, the consortium published results of its sequencing effort in Science. The genome, 85% of which is composed of transposons, was found to contain 32,540 genes (By comparison, the human genome contains about 2.9 billion bases and 26,000 genes). Much of the maize genome has been duplicated and reshuffled by helitrons—group of rolling circle transposons.
In Z. mays and various other angiosperms the MADS-box motif is involved in floral development. Early study in several angiosperm models including Z. mays was the beginning of research into the molecular evolution of floral structure in general, as well as their role in nonflowering plants.
EVOLUTION
As with many plants and animals, Z. mays has a positive correlation between effective population size and the magnitude of selection pressure. Z. m. having an EPS of ~650,000, it clusters with others of about the same EPS, and has 79% of its amino acid sites under selection.
Recombination is a significant source of diversity in Z. mays. (Note that this finding supersedes previous studies which showed no such correlation.)
This recombination/diversity effect is seen throughout plants but is also found to not occur – or not as strongly – in regions of high gene density. This is likely the reason that domesticated Z. mays has not seen as much of an increase in diversity within areas of higher density as in regions of lower density, although there is more evidence in other plants.
Some lines of maize have undergone ancient polyploidy events, starting 11m years ago. Over that time ~72% of polyploid duplicated genes have been retained, which is higher than other plants with older polyploidy events. Thus maize may be due to lose more duplicate genes as time goes along, similar to the course followed by the genomes of other plants. If so - if gene loss has merely not occurred yet - that could explain the lack of observed positive selection and lower negative selection which are observed in otherwise similar plants, i.e. also naturally outcrossing and with similar effective population sizes.
Ploidy does not appear to influence EPS or magnitude of selection effect in maize.
BREEDING
Maize reproduces sexually each year. This randomly selects half the genes from a given plant to propagate to the next generation, meaning that desirable traits found in the crop (like high yield or good nutrition) can be lost in subsequent generations unless certain techniques are used.
Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of the earliest and most successful developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection. Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and the highly successful double cross hybrids using four inbred lines (D. F. Jones c. 1918, 1922). University supported breeding programs were especially important in developing and introducing modern hybrids. By the 1930s, companies such as Pioneer devoted to production of hybrid maize had begun to influence long-term development. Internationally important seed banks such as the International Maize and Wheat Improvement Center (CIMMYT) and the US bank at the Maize Genetics Cooperation Stock Center University of Illinois at Urbana-Champaign maintain germplasm important for future crop development.
Since the 1940s the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic modification have succeeded in increasing output and reducing the need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant.
Tropical landraces remain an important and underutilized source of resistance alleles for for disease and for herbivores. Notable discoveries of rare alleles for this purpose were made by Dao et al 2014 and Sood et al 2014.
GLOBAL PROGRAM
CIMMYT operates a conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by the Drought Tolerant Maize for Africa project.
GENETIC MODIFICATION
Genetically modified (GM) maize was one of the 26 GM crops grown commercially in 2016. The vast majority of this is Bt maize. Grown since 1997 in the United States and Canada, 92% of the US maize crop was genetically modified in 2016 and 33% of the worldwide maize crop was GM in 2016. As of 2011, Herbicide-tolerant maize varieties were grown in Argentina, Australia, Brazil, Canada, China, Colombia, El Salvador, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, the Russian Federation, Singapore, South Africa, Taiwan, Thailand, and the United States. Insect-resistant maize was grown in Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, South Africa, Switzerland, Taiwan, the United States, and Uruguay.
In September 2000, up to $50 million worth of food products were recalled due to the presence of Starlink genetically modified corn, which had been approved only for animal consumption and had not been approved for human consumption, and was subsequently withdrawn from the market.
ORIGIN
Maize is the domesticated variant of teosinte. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between the two is largely controlled by differences in just two genes, called grassy tillers-1 (gt1, A0A317YEZ1) and teosinte branched-1 (tb1, Q93WI2).
Several theories had been proposed about the specific origin of maize in Mesoamerica:
It is a direct domestication of a Mexican annual teosinte, Zea mays ssp. parviglumis, native to the Balsas River valley in south-eastern Mexico, with up to 12% of its genetic material obtained from Zea mays ssp. mexicana through introgression.
It has been derived from hybridization between a small domesticated maize (a slightly changed form of a wild maize) and a teosinte of section Luxuriantes, either Z. luxurians or Z. diploperennis.
It has undergone two or more domestications either of a wild maize or of a teosinte. (The term "teosinte" describes all species and subspecies in the genus Zea, excluding Zea mays ssp. mays.)
It has evolved from a hybridization of Z. diploperennis by Tripsacum dactyloides.
In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum, a related genus. This theory about the origin of maize has been refuted by modern genetic testing, which refutes Mangelsdorf's model and the fourth listed above.
The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931 and the later American Nobel Prize-winner George Beadle in 1932.: 10 It is supported experimentally and by recent studies of the plants' genomes. Teosinte and maize can cross-breed and produce fertile offspring. A number of questions remain concerning the species, among them:
how the immense diversity of the species of sect. Zea originated,
how the tiny archaeological specimens of 3500–2700 BC could have been selected from a teosinte, and
how domestication could have proceeded without leaving remains of teosinte or maize with teosintoid traits earlier than the earliest known until recently, dating from ca. 1100 BC.
The domestication of maize is of particular interest to researchers—archaeologists, geneticists, ethnobotanists, geographers, etc. The process is thought by some to have started 7,500 to 12,000 years ago. Research from the 1950s to 1970s originally focused on the hypothesis that maize domestication occurred in the highlands between the states of Oaxaca and Jalisco, because the oldest archaeological remains of maize known at the time were found there.
Connection with 'parviglumis' subspecies
Genetic studies, published in 2004 by John Doebley, identified Zea mays ssp. parviglumis, native to the Balsas River valley in Mexico's southwestern highlands, and also known as Balsas teosinte, as being the crop wild relative that is genetically most similar to modern maize. This was confirmed by further studies, which refined this hypothesis somewhat. Archaeobotanical studies, published in 2009, point to the middle part of the Balsas River valley as the likely location of early domestication; this river is not very long, so these locations are not very distant. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero.
Doebley was part of the team that first published, in 2002, that maize had been domesticated only once, about 9,000 years ago, and then spread throughout the Americas.
A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley, date back roughly 6,250 years; the oldest ears from caves near Tehuacan, Puebla, 5,450 B.P.
Maize pollen dated to 7,300 B.P. from San Andres, Tabasco, on the Caribbean coast has also been recovered.
As maize was introduced to new cultures, new uses were developed and new varieties selected to better serve in those preparations. Maize was the staple food, or a major staple – along with squash, Andean region potato, quinoa, beans, and amaranth – of most pre-Columbian North American, Mesoamerican, South American, and Caribbean cultures. The Mesoamerican civilization, in particular, was deeply interrelated with maize. Its traditions and rituals involved all aspects of maize cultivation – from the planting to the food preparation. Maize formed the Mesoamerican people's identity.
It is unknown what precipitated its domestication, because the edible portion of the wild variety is too small, and hard to obtain, to be eaten directly, as each kernel is enclosed in a very hard bivalve shell.
In 1939, George Beadle demonstrated that the kernels of teosinte are readily "popped" for human consumption, like modern popcorn. Some have argued it would have taken too many generations of selective breeding to produce large, compressed ears for efficient cultivation. However, studies of the hybrids readily made by intercrossing teosinte and modern maize suggest this objection is not well founded.
SPREADING TO THE NORTH
Around 4,500 ago, maize began to spread to the north; it was first cultivated in what is now the United States at several sites in New Mexico and Arizona, about 4,100 ago.
During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for the new crop.
In 2005, research by the USDA Forest Service suggested that the rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels, which are very sensitive to environmental changes.
CULTIVATION
PLANTING
Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As a plant that uses C4 carbon fixation, maize is a considerably more water-efficient crop than plants that use C3 carbon fixation such as alfalfa and soybeans. Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July", although modern hybrids generally exceed this growth rate. Maize used for silage is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine. Although it is grown mainly in wet, hot climates, it has been said to thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop.
Maize was planted by the Native Americans in hills, in a complex system known to some as the Three Sisters. Maize provided support for beans, and the beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. This method was replaced by single species hill planting where each hill 60–120 cm (2 ft 0 in–3 ft 11 in) apart was planted with three or four seeds, a method still used by home gardeners. A later technique was "checked maize", where hills were placed
1 m (40 in) apart in each direction, allowing cultivators to run through the field in two directions. In more arid lands, this was altered and seeds were planted in the bottom of 10–12 cm (4–4+1⁄2 in) deep furrows to collect water. Modern technique plants maize in rows which allows for cultivation while the plant is young, although the hill technique is still used in the maize fields of some Native American reservations. When maize is planted in rows, it also allows for planting of other crops between these rows to make more efficient use of land space.
In most regions today, maize grown in residential gardens is still often planted manually with a hoe, whereas maize grown commercially is no longer planted manually but rather is planted with a planter. In North America, fields are often planted in a two-crop rotation with a nitrogen-fixing crop, often alfalfa in cooler climates and soybeans in regions with longer summers. Sometimes a third crop, winter wheat, is added to the rotation.
Many of the maize varieties grown in the United States and Canada are hybrids. Often the varieties have been genetically modified to tolerate glyphosate or to provide protection against natural pests. Glyphosate is an herbicide which kills all plants except those with genetic tolerance. This genetic tolerance is very rarely found in nature.
In the midwestern United States, low-till or no-till farming techniques are usually used. In low-till, fields are covered once, maybe twice, with a tillage implement either ahead of crop planting or after the previous harvest. The fields are planted and fertilized. Weeds are controlled through the use of herbicides, and no cultivation tillage is done during the growing season. This technique reduces moisture evaporation from the soil, and thus provides more moisture for the crop. The technologies mentioned in the previous paragraph enable low-till and no-till farming. Weeds compete with the crop for moisture and nutrients, making them undesirable.
HARVESTING
Before the 20th century, all maize harvesting was by manual labour, by grazing, or by some combination of those. Whether the ears were hand-picked and the stover was grazed, or the whole plant was cut, gathered, and shocked, people and livestock did all the work. Between the 1890s and the 1970s, the technology of maize harvesting expanded greatly. Today, all such technologies, from entirely manual harvesting to entirely mechanized, are still in use to some degree, as appropriate to each farm's needs, although the thoroughly mechanized versions predominate, as they offer the lowest unit costs when scaled to large farm operations. For small farms, their unit cost can be too high, as their higher fixed cost cannot be amortized over as many units.[citation needed]
Before World War II, most maize in North America was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover) and corn binders, which are reaper-binders designed specifically for maize (for example, Video on YouTube). The latter produce sheaves that can be shocked. By hand or mechanical picker, the entire ear is harvested, which then requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs, and these whole ears are a sufficient form for some livestock feeding use. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine and store it in bins. The combine with a corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil. The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter the machinery. The combine separates the husk and the cob, keeping only the kernels.
When maize is a silage crop, the entire plant is usually chopped at once with a forage harvester (chopper) and ensiled in silos or polymer wrappers. Ensiling of sheaves cut by a corn binder was formerly common in some regions but has become uncommon. For storing grain in bins, the moisture of the grain must be sufficiently low to avoid spoiling. If the moisture content of the harvested grain is too high, grain dryers are used to reduce the moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases (propane or natural gas) and electricity to power the blowers.
PRODUCTION
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2018, total world production was 1.15 billion tonnes, led by the United States with 34.2% of the total (table). China produced 22.4% of the global total.
UNITED STATES
In 2016, maize production was forecast to be over 380 million metric tons (15 billion bushels), an increase of 11% over 2014 American production. Based on conditions as of August 2016, the expected yield would be the highest ever for the United States. The area of harvested maize was forecast to be 35 million hectares (87 million acres), an increase of 7% over 2015. Maize is especially popular in Midwestern states such as Indiana, Iowa, and Illinois; in the latter, it was named the state's official grain in 2017.
STORAGE
Drying is vital to prevent or at least reduce mycotoxin contamination. Aspergillus and Fusarium spp. are the most common mycotoxin sources, but there are others. Altogether maize contaminants are so common, and this crop is so economically important, that maize mycotoxins are among the most important in agriculture in general.
USES
HUMAN FOOD
Maize and cornmeal (ground dried maize) constitute a staple food in many regions of the world. Maize is used to produce cornstarch, a common ingredient in home cooking and many industrialized food products. Maize starch can be hydrolyzed and enzymatically treated to produce syrups, particularly high fructose corn syrup, a sweetener; and also fermented and distilled to produce grain alcohol. Grain alcohol from maize is traditionally the source of Bourbon whiskey. Corn flour is used to make cornbread and other baked products.
In prehistoric times Mesoamerican women used a metate to process maize into ground cornmeal, allowing the preparation of foods that were more calorie dense than popcorn. After ceramic vessels were invented the Olmec people began to cook maize together with beans, improving the nutritional value of the staple meal. Although maize naturally contains niacin, an important nutrient, it was not bioavailable without the process of nixtamalization. The Maya used nixtamal meal to make varieties of porridges and tamales. The process was later used in the cuisine of the American South to prepare corn for grits and hominy.
Maize is a staple of Mexican cuisine. Masa (cornmeal treated with limewater) is the main ingredient for tortillas, atole and many other dishes of Central American food. It is the main ingredient of corn tortilla, tamales, pozole, atole and all the dishes based on them, like tacos, quesadillas, chilaquiles, enchiladas, tostadas and many more. In Mexico the fungus of maize, known as huitlacoche, is considered a delicacy.
Coarse maize meal is made into a thick porridge in many cultures: from the polenta of Italy, the angu of Brazil, the mămăligă of Romania, to cornmeal mush in the US (or hominy grits in the South) or the food called mieliepap in South Africa and sadza, nshima, ugali and other names in other parts of Africa. Introduced into Africa by the Portuguese in the 16th century, maize has become Africa's most important staple food crop. These are commonly eaten in the Southeastern United States, foods handed down from Native Americans, who called the dish sagamite.
Maize can also be harvested and consumed in the unripe state, when the kernels are fully grown but still soft. Unripe maize must usually be cooked to become palatable; this may be done by simply boiling or roasting the whole ears and eating the kernels right off the cob. Sweet corn, a genetic variety that is high in sugars and low in starch, is usually consumed in the unripe state. Such corn on the cob is a common dish in the United States, Canada, United Kingdom, Cyprus, some parts of South America, and the Balkans, but virtually unheard of in some European countries. Corn on the cob was hawked on the streets of early 19th-century New York City by poor, barefoot "Hot Corn Girls", who were thus the precursors of hot dog carts, churro wagons, and fruit stands seen on the streets of big cities today.
Within the United States, the usage of maize for human consumption constitutes only around 1/40th of the amount grown in the country. In the United States and Canada, maize is mostly grown to feed livestock, as forage, silage (made by fermentation of chopped green cornstalks), or grain. Maize meal is also a significant ingredient of some commercial animal food products.
NUTRITIONAL VALUE
Raw, yellow, sweet maize kernels are composed of 76% water, 19% carbohydrates, 3% protein, and 1% fat (table). In a 100-gram serving, maize kernels provide 86 calories and are a good source (10–19% of the Daily Value) of the B vitamins, thiamin, niacin (but see Pellagra warning below), pantothenic acid (B5) and folate (right table for raw, uncooked kernels, USDA Nutrient Database). In moderate amounts, they also supply dietary fiber and the essential minerals, magnesium and phosphorus whereas other nutrients are in low amounts (table).
Maize has suboptimal amounts of the essential amino acids tryptophan and lysine, which accounts for its lower status as a protein source. However, the proteins of beans and legumes complement those of maize.
FEED AND FODDER FOR LIVESTOCK
Maize is a major source of both grain feed and fodder for livestock. It is fed to the livestock in various ways. When it is used as a grain crop, the dried kernels are used as feed. They are often kept on the cob for storage in a corn crib, or they may be shelled off for storage in a grain bin. The farm that consumes the feed may produce it, purchase it on the market, or some of both. When the grain is used for feed, the rest of the plant (the corn stover) can be used later as fodder, bedding (litter), or soil amendment. When the whole maize plant (grain plus stalks and leaves) is used for fodder, it is usually chopped all at once and ensilaged, as digestibility and palatability are higher in the ensilaged form than in the dried form. Maize silage is one of the most valuable forages for ruminants. Before the advent of widespread ensilaging, it was traditional to gather the corn into shocks after harvesting, where it dried further. With or without a subsequent move to the cover of a barn, it was then stored for weeks to several months until fed to the livestock. Today ensilaging can occur not only in siloes but also in silage wrappers. However, in the tropics, maize can be harvested year-round and fed as green forage to the animals.
CHEMICALS
Starch from maize can also be made into plastics, fabrics, adhesives, and many other chemical products.
The corn steep liquor, a plentiful watery byproduct of maize wet milling process, is widely used in the biochemical industry and research as a culture medium to grow many kinds of microorganisms.
Chrysanthemin is found in purple corn and is used as a food coloring.
BIO-FUEL
"Feed maize" is being used increasingly for heating; specialized corn stoves (similar to wood stoves) are available and use either feed maize or wood pellets to generate heat. Maize cobs are also used as a biomass fuel source. Maize is relatively cheap and home-heating furnaces have been developed which use maize kernels as a fuel. They feature a large hopper that feeds the uniformly sized maize kernels (or wood pellets or cherry pits) into the fire.[citation needed]
Maize is increasingly used as a feedstock for the production of ethanol fuel. When considering where to construct an ethanol plant, one of the site selection criteria is to ensure there is locally available feedstock. Ethanol is mixed with gasoline to decrease the amount of pollutants emitted when used to fuel motor vehicles. High fuel prices in mid-2007 led to higher demand for ethanol, which in turn led to higher prices paid to farmers for maize. This led to the 2007 harvest being one of the most profitable maize crops in modern history for farmers. Because of the relationship between fuel and maize, prices paid for the crop now tend to track the price of oil.
The price of food is affected to a certain degree by the use of maize for biofuel production. The cost of transportation, production, and marketing are a large portion (80%) of the price of food in the United States. Higher energy costs affect these costs, especially transportation. The increase in food prices the consumer has been seeing is mainly due to the higher energy cost. The effect of biofuel production on other food crop prices is indirect. Use of maize for biofuel production increases the demand, and therefore price of maize. This, in turn, results in farm acreage being diverted from other food crops to maize production. This reduces the supply of the other food crops and increases their prices.
Maize is widely used in Germany as a feedstock for biogas plants. Here the maize is harvested, shredded then placed in silage clamps from which it is fed into the biogas plants. This process makes use of the whole plant rather than simply using the kernels as in the production of fuel ethanol.
A biomass gasification power plant in Strem near Güssing, Burgenland, Austria, began in 2005. Research is being done to make diesel out of the biogas by the Fischer Tropsch method.
Increasingly, ethanol is being used at low concentrations (10% or less) as an additive in gasoline (gasohol) for motor fuels to increase the octane rating, lower pollutants, and reduce petroleum use (what is nowadays also known as "biofuels" and has been generating an intense debate regarding the human beings' necessity of new sources of energy, on the one hand, and the need to maintain, in regions such as Latin America, the food habits and culture which has been the essence of civilizations such as the one originated in Mesoamerica; the entry, January 2008, of maize among the commercial agreements of NAFTA has increased this debate, considering the bad labor conditions of workers in the fields, and mainly the fact that NAFTA "opened the doors to the import of maize from the United States, where the farmers who grow it receive multimillion-dollar subsidies and other government supports. ... According to OXFAM UK, after NAFTA went into effect, the price of maize in Mexico fell 70% between 1994 and 2001. The number of farm jobs dropped as well: from 8.1 million in 1993 to 6.8 million in 2002. Many of those who found themselves without work were small-scale maize growers."). However, introduction in the northern latitudes of the US of tropical maize for biofuels, and not for human or animal consumption, may potentially alleviate this.
COMMODITY
Maize is bought and sold by investors and price speculators as a tradable commodity using corn futures contracts. These "futures" are traded on the Chicago Board of Trade (CBOT) under ticker symbol C. They are delivered every year in March, May, July, September, and December.
ORNAMENTAL AND OTHER USES
Some forms of the plant are occasionally grown for ornamental use in the garden. For this purpose, variegated and colored leaf forms as well as those with colorful ears are used.
Corncobs can be hollowed out and treated to make inexpensive smoking pipes, first manufactured in the United States in 1869.
An unusual use for maize is to create a "corn maze" (or "maize maze") as a tourist attraction. The idea of a maize maze was introduced by the American Maze Company who created a maze in Pennsylvania in 1993. Traditional mazes are most commonly grown using yew hedges, but these take several years to mature. The rapid growth of a field of maize allows a maze to be laid out using GPS at the start of a growing season and for the maize to grow tall enough to obstruct a visitor's line of sight by the start of the summer. In Canada and the US, these are popular in many farming communities.
Maize kernels can be used in place of sand in a sandboxlike enclosure for children's play.
Stigmas from female maize flowers, popularly called corn silk, are sold as herbal supplements.
Maize is used as a fish bait, called "dough balls". It is particularly popular in Europe for coarse fishing.
Additionally, feed corn is sometimes used by hunters to bait animals such as deer or wild hogs.
UNITED STATES USAGE BREAKDOWN
The breakdown of usage of the 12.1-billion-bushel (307-million-tonne) 2008 US maize crop was as follows, according to the World Agricultural Supply and Demand Estimates Report by the USDA.In the US since 2009/2010, maize feedstock use for ethanol production has somewhat exceeded direct use for livestock feed; maize use for fuel ethanol was 5,130 million bushels (130 million tonnes) in the 2013/2014 marketing year.A fraction of the maize feedstock dry matter used for ethanol production is usefully recovered as DDGS (dried distillers grains with solubles). In the 2010/2011 marketing year, about 29.1 million tonnes of DDGS were fed to US livestock and poultry. Because starch utilization in fermentation for ethanol production leaves other grain constituents more concentrated in the residue, the feed value per kg of DDGS, with regard to ruminant-metabolizable energy and protein, exceeds that of the grain. Feed value for monogastric animals, such as swine and poultry, is somewhat lower than for ruminants.
HAZARDS
PELLAGRA
When maize was first introduced into farming systems other than those used by traditional native-American peoples, it was generally welcomed with enthusiasm for its productivity. However, a widespread problem of malnutrition soon arose wherever maize was introduced as a staple food. This was a mystery, since these types of malnutrition were not normally seen among the indigenous Americans, for whom maize was the principal staple food.
It was eventually discovered that the indigenous Americans had learned to soak maize in alkali — water (the process now known as nixtamalization) — made with ashes and lime (calcium oxide) since at least 1200–1500 BC by Mesoamericans. They did this to liberate the corn hulls, but (unbeknownst to natives or colonists) it coincidentally liberates the B-vitamin niacin, the lack of which was the underlying cause of the condition known as pellagra.
Maize was introduced into the diet of non-indigenous Americans without the necessary cultural knowledge acquired over thousands of years in the Americas. In the late 19th century, pellagra reached epidemic proportions in parts of the southern US, as medical researchers debated two theories for its origin: the deficiency theory (which was eventually shown to be true) said that pellagra was due to a deficiency of some nutrient, and the germ theory said that pellagra was caused by a germ transmitted by stable flies. A third theory, promoted by the eugenicist Charles Davenport, held that people only contracted pellagra if they were susceptible to it due to certain "constitutional, inheritable" traits of the affected individual.
Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high lysine maize and the promotion of a more balanced diet have also contributed to its demise. Pellagra still exists today in food-poor areas and refugee camps where people survive on donated maize.
ALLERGY
Maize contains lipid transfer protein, an indigestible protein that survives cooking. This protein has been linked to a rare and understudied allergy to maize in humans. The allergic reaction can cause skin rash, swelling or itching of mucous membranes, diarrhea, vomiting, asthma and, in severe cases, anaphylaxis. It is unclear how common this allergy is in the general population.
MYCOTOXINS
Fungicide application does not reduce fungal growth or mycotoxin dramatically, although it can be a part of a successful reduction strategy. Among the most common toxins are those produced by Aspergillus and Fusarium spp. The most common toxins are aflatoxins, fumonisins, zearalenone, and ochratoxin A. Bt maize discourages insect vectors and by so doing it dramatically reduces concentrations of fumonisins, significantly reduces aflatoxins, but only mildly reduces others.
ART
Maize has been an essential crop in the Andes since the pre-Columbian era. The Moche culture from Northern Peru made ceramics from earth, water, and fire. This pottery was a sacred substance, formed in significant shapes and used to represent important themes. Maize was represented anthropomorphically as well as naturally.
In the United States, maize ears along with tobacco leaves are carved into the capitals of columns in the United States Capitol building. Maize itself is sometimes used for temporary architectural detailing when the intent is to celebrate the fall season, local agricultural productivity and culture. Bundles of dried maize stalks are often displayed along with pumpkins, gourds and straw in autumnal displays outside homes and businesses. A well-known example of architectural use is the Corn Palace in Mitchell, South Dakota, which uses cobs and ears of colored maize to implement a mural design that is recycled annually. Another well-known example is the Field of Corn sculpture in Dublin, Ohio, where hundreds of concrete ears of corn stand in a grassy field.
A maize stalk with two ripe ears is depicted on the reverse of the Croatian 1 lipa coin, minted since 1993.

Now I just need a bow, full masts, rigging and sails. The fun part is over!
Roughly as long as a 4 midsection prefab ship, but the overall shape is much different; at it's widest (the middle) it is ~17 studs wide, at the bow 14-15, at the stern 12. A shape basically impossible to reach with prefab hulls (besides, I'm out of those (besides 2 brown sterns, 4 dk brown midsections, 2 red ones and 1 reddish brown ones - not exactly combinable). While the colourscheme might be debatable, I dare to say that this will be my best looking ship so far once done (as it will be done long before my 5th rate)

The Chrysler 300 'letter series' were high-performance personal luxury cars built by Chrysler from 1955-65, a sub-model of the Chrysler New Yorker. After the initial year, which was named C-300 for its standard 300 hp 331 cu in FirePower V8, the 1956 cars were designated 300B. Successive model years were given the next letter of the alphabet, reaching the 300L by 1965.
The original C-300 was developed to homologate a Chrysler for the NASCAR circuits. The front clip, including the grille, was taken from the Imperial of the same year, the midsection was from a New Yorker hardtop, with a Windsor rear quarter. The 1956 update was the 300B, with new tailfins and a larger engine. Two companions of the 300B were introduced; the DeSoto Adventurer and the Dodge D-500, less luxurious, but sharing much of the mechanicals.
Engine; 354 cu in Hemi V8 with either 340 or 355 hp. Only 1,102 300 Bs were sold

So I was mucking about thinking of a future project, when I started wondering how the cement mixer pieces would look on a rocket. The only part I'm not liking are the 1x1 round bricks in the midsection. Also, the lattice pieces don'e come in red, which is a shame.
This final view of Duluth's vertical-lift bridge image was, like the preceding two, taken from Enger Tower. We're facing east-northeastward.
For more on the bridge's history and design changes, see Part I. And to see this bridge in its "down" position, see Part 2.
In this case, the bridge's central roadway section has been hoisted up so that an absolute sweet pea of a laker (Great Lakes freighter) can make her graceful way from Duluth's harbor into open waters.
Long before I knew this ship's identity, I knew she was old, and considerably older than I. The stovepipe funnel and the elegant counter stern are both signs of an early-twentieth-century design.
Also notice a more persistent feature of laker anatomy: the bridge superstructure is full forward: and the engine house, full aft. That results in a lot of cargo space in between.
If my subsequent research has not mislead me, this grande dame is the SS Alpena, currently the senior vessel of her type plying the Great Lakes. First commissioned in 1942 and originally named the Leon Fraser, she started her career 120 ft (36.6 m) longer than she is now. In 1990, she was shortened by cutting out her midsection. Recommissioned as the Alpena, she was converted into a cement carrier.
It was sheer luck that I happened to be up in Enger Tower with a tour group when the Aerial Lift Bridge and the Alpena shared the same space. My only regret at the time: that I wasn't sailing away with the latter, to visit various out-of-the-way ports of call on this vast expanse of fresh water. To repeat an old maxim from my Navy days: Underway Is the Only Way.
The other photos and descriptions of this series can be found in my Love of Bridges album.
Designer Jasmine has been completely deboxed, then placed back on her doll stand, and the acrylic cover placed back on. The cardboard backing has been cut off from the base of the stand, so the doll can be seen from all angles. It also makes replacing and taking off the acrylic cover much easier. To fit the outfit in the case, and to show the inner skirt and hanging pendant and chain, the overskirt was folded over on both sides.
First look at the Disney Princess Designer Collection Jasmine Doll. She was released in October 2011, and I got her from eBay shortly afterwards, so It's been more than a year and a half since I got this doll. But I have not yet deboxed her, and this the first time I am doing a full photoshoot of her. I will photograph her boxed, during her deboxing, and fully deboxed.
My Designer Jasmine doll is a limited edition doll that was produced and sold exclusively by the Disney Store, and is numbered 5645 of 6000. She is based on the heroine from the Disney animated feature Aladdin (1992). She comes in an acrylic case with a built-in doll stand, with a base that has a golden filigree design, and a golden metallic nameplate. There is also a cardboard cover for the case that I have not photographed here.
She is 11 1/2'' tall, and has the same body as the other Designer Princess dolls, with jointed neck, shoulders, elbows, wrists, waist, hips and knees (internal). She has rubber legs and fixed ankles, with feet angled for high heels.
She has jet black, 12'' long hair tied into a floor length pony tail. There are two golden elastic hairties in the upper and middle part of the ponytail, and the lower portion of her hair has loose curls. It is very soft and shiny. There were a few stray hairs, but I left them alone and did not comb it, as I thought her hair was neat enough as it was out of the box. She has light brown skin, and a unique face sculpt that is very pretty and movie accurate. She has large dark brown almond shaped eyes that are glancing towards her right. She has light blue-green eye shadow, and thick black eyebrows. She has rooted eyelashes, that are tapered in length from short to long, then at the ends there are very long curved antenna like lashes. She has a small straight nose, full dark purple lips in with a closed mouth smile. She has very pale red rouge on her cheeks.
Her three piece gown is made of bright blue-green satin and light blue organza. Her bodice is cropped short to reveal her midsection (including her belly button), and consists of light blue organza embedded with golden gems, draped over her upper arms, and gemmed blue-green satin lower and back sections. Her blue-green satin skirt is floor length and is figure hugging, flairing out at the bottom. It is hemmed and there is a light blue polyester lining. There is a very wide overskirt of the double layered light blue satin. I is open in front, but can be wrapped around to completely cover her inner skirt, or can be folded to reveal her inner skirt.
She is wearing light blue-green high heeled shoes, which match the color of her skirt.
Her accessories include earrings, a chain belt with pendant and Aladdin's lamp. The earrings are large golden triangles with gold colored gems. Her belt is made of fine gold chain, with a large round jeweled pendant just below her waist that gathers the strands of the chain together, the remainder of which fall almost to the floor. In her right hand is a golden lamp that is bejeweled with yellow gems. The top of the lamp is removable (it is held in place with rubber bands, which I left in place).
There were no real surprises revealed by deboxing her, although it was nice to see the full extent of her overskirt. I was also glad to take her out of her awkward head pose, which was a common problem among the Designer Princesses. One thing I didn't like was that her top was a little too short, and revealed her waist joint (that enables her to spin her upper body around 360 degrees). Tugging on her top didn't move it enough to hide the joint in the front. As a consequence, her waist joint moved very freely, and her upper body tended to turn whenever she was handled, aided by her long hair. Also her long luxurious hair is very heavy, so tends to pull her backwards slightly when she is posed on the display stand. Designer Rapunzel has a similar problem. Her very wide floor length overskirt and floor length hair make it difficult to rebox her neatly, which is a common problem with the Designer dolls with very wide floor length skirts.
This started out as a Vic Viper but ended up taking some traits from R-type ships as well(high mounted engines, bulky midsection) It still needs some internal structure changes but t's pretty much done for now!

What started it
Amara stood up, storming off to the edge of the bed. Here she was feeling bad for herself and Rico just acted like nothing had happened. "I'm not apologizing for giving an ungrateful bitch like you a vaccine to save your life…but don't expect treatment from the medics you're so fucking convinced are useless!" She started for the stairs. "Next time your dumbass decides to get deliberately infected, do the family a favor and stay away from the Den!"
Tanner 's ears twitched at this point, frowning as he looked over to Rico, feeling Amara's emotions still, sadness and maybe just a little anger. He shook his head at this point before letting out, "what the fuck did you do!" he lets out angrily as he tries to get himself up from the wall. His own mix up emotions weren't helping. He was volitile right now and Amara's emotions weren't helping in the least. He narrows his eyes a bit before limping over towards the other.
Rico didnt pay anymind to her. He didnt think the medics in general were useless. Sure he was mad she took forever but this could have been avoided if she didnt threaten him and then shock him 5 seconds after being shocked. He heard tanner and sighed "I asked her not to talk to me.....if she wants to shock me and threaten me then theres nor reason to talk to me.....So I told her not to speak to me" he shrugs as he wasnt going to apologize for anything he said she wouldnt stop talking to him so she made him say that. He knew she was probably going to tell alot of packies and they werent going to like him anymore but its just that way he assumed
(( Patman Ballinger: no*))
"News Flash jerk. When you disrespect an Elder, you get punished. I walked out on my wife to come here yesterday….I left her alone at a fucking restaurant, our private time after several days of working on different schedules…to run over here to treat Yvonne. And you send a rude, ungrateful text across the entire Pack channel because you didn't feel like waiting!" Amara paced around for a few seconds. "After all, that you go and jeopardize the treatment by deliberately kissing your infected lover…and I'm the bad one for giving you a vaccine?!"
Tanner 's ears flattened against his head at this point as he shook his head, taking a deep breath before murmuring out, "I don't know exactly what happened... but sounds like you're being an asshole Rico..." he lets out, looking to Amara, "I... I shouldn't stay here... I'm... just gonna make things worse..." he lets out, knowing he's getting angry and upset and more confused and depressed then he already is.
Rico shakes his head "Fine Im an asshole" he throws his hands in the air. "Look at me the biggest asshole ever " he hops down off the ledge and to the pool below and goes into the back of the part of the cave to be alone "The asshole will be downstairs if you need it" he said down and laid his head on the rock closing his eyes
Amara snarled, a more animalistic bellow than a hybrid feline would technically make. Fists clenched tight enough to draw blood, she'd storm after the sarcastic Rico. Now would be a smart time to hold her back…because after admitting all this sacrifice just to hear Rico blow it off like it meant nothing, Amara was not about to tell him off…oh no…she was ready to kill him.
Editor's note: *rings fight bell*
Tanner wouldn't hold her back though... he wasn't in a state of mind to do so... not with Amara's emotions as we as his own engulphing his mind. He clenched his fists and knawed his lip as he backed up some trying not to trip or anything as he tried to get away from Amara and her emotions before he did something that he'd regret. His heart was thumping in his chest before he shook his head and let out a loud scream before starting to sob softly, hands coming to his hair, injured shoulder aching a bit as he dropped to his knees trying to create an invisible sphere around himself like Alexandra was trying to teach him... it wasn't working though.
Rico heard the snarl but didnt think anything of it at the time. He scratched a his chin with a yawn before looking back at the wwater
Without Tanner to stop her, Amara jumped down to the pool, landing easily on her feet. The snarls never ceased to leave her lips, a challenging noise to the ears of panther. She'd prowl outside the grotto, snapping in a fit of loud growls and hissing, the sounds being the equivalent of curses deliberate enough to provoke Rico in their native feline dialect.
" You spineless ungrateful coward! If you want to run away from a conversation that badly, just say so!"
Rico was insulted at this and this was just nature but panthers werent an animal to turn down such calls. He angrily growled before turning over and walking through the falls to meet the call. He growled the yellow feline eyes on her as his claws came out. He opened his mouth in what almost looked like a smile but it was to show his canines in intimidations as he snarled back angrily
Amara knelt for a moment at the reply, not out of fear but merely bracing herself in case he charged. She raised her left hand, presenting her natural claws to the male as a message she would not be backing down to him. Her rank was important, and Amara had every intention of making that message clear in the hisses she returned.
Tanner tugged on his hair before shaking his head, shouting loudly, "STOP IT! STOP IT! STOP IT!" His claws dug into his scalp as he growled out, tears slipping down his cheeks as his eyes became rimmed with crimson, pupils getting larger as he stared at the ground.
Rico crouched down snarling and snapping. He indeed had no doubt she wouldnt back down but neither was he. When he was created his scientist wanteed to see how far a panther could be fused into a human. So his willingness to accept a challege was high. He continued the showing of his canines ignoring the pleas to stop. Hisses escaped his lips as he looked at her . His body lowered but he wasnt going to charge first with his size one bad charge could take him out the fight
Patman Ballinger: ((Trans)) Im not backing down....You wanna fight me thenfine I tried to walk from this issue
Amara took advantage of this hesitation, lunging forward to attack his midsection. A quick sweep with her left hand lashed out at the male panther, both hand and tongue desiring blood. The howling reflected her disgust in him, again repeating taunting growls and roars intent to demean him. In the wild, such noises were reminiscent of a female disapproving a weaker suitor.
Amara Parmelee: ((trans)) You did nothing of the sort! You pouted and turned your back like some angry child at nursery. Pathetic...why did I waste my time trying to treat you at all?!
Rico started back before a burning came across his stomache. Fresh claw marks began to bleed which didnt make the male panther too happy. He snarled loudly his right hand camed down in a club like motion hoping to rake his sharp claws down the side of her cheek. A snarl given taunting the female panther that most would take as an insult to their sex in the big cat world. He wanted nothing more than to sink his teeth into her neck . He snapped again in her direction before giving a call as if he claimed superiority in this battle
Patman Ballinger: ((Trans))Now you insult me? And spill my blood...FINE..... I did not ask you to fight........I told you to leave me alone...But you keep on talking. I told you not to treat me so you wasted your own time I asked you not to!!!!!
Tanner 's fingers dug into his scalp as he just stared at the ground, breath coming out in short little gasps as his usually golden eyes became crimson, pupils getting bigger and smaller as he stared at the ground. His claws were finally removed from his scalp as he slowly got to his feet, eyes narrowed dangerously as he moved towards the stairs, limping slightly but not seeming to be in any pain anymore.
Amara was not about to let Rico actually mark her in this fight. She braced for the impact which sent her flying rudely into the waters of the pool. Sitting up immediately and panting heavily, Amara spit the bit of blood from her mouth that was caused by the bruising. Several hisses went let out in Rico's direction. Running some water over her face, she adjusted her stance, flicking her ears in retaliation at Rico's bold proclamation of victory. She launched herself in the air this time, intent on landing a swift right hook to his face.
Amara Parmelee: ((trans)) If you wished to die so badly, just say so weakling! I won't have you infecting the entire family for your fucking pride! I'll have you show some damn respect before this is over.
Rico snarled as his swipe hit but it was short lived as he saw her lunge. His head snappedto the side as he tumbled meeting not water but just more rock. He groaned as his body met the hard surface but he shook his head moving back into his stance. His face now with fresh claw marks he could let that go. He lunged forward upon getting up his face and belly burned but his right raised a claws attempting to slam and rake hard at the top of her heard and forehead heavy snarls as he did
(( Patman Ballinger: couldnt*))
Patman Ballinger: ((Trans)) I dont get infected like most. If I get a cold its small and its not serious. I respected you until you threaten me and shock me....You know im still shook from the last time I was left behind by packies *Swipe* But no instead of just leaving me be you want to be an aggressor....I refuse to kill you but ill defend myself and make sure its know you started this!!!!
arwen Eiren wanders into the den arms crossed over her chest , her small eyes widen as she could see the fight , ears pinningb back against her head standing there"m.....mama!"she saw Rico attacking her mama, She lets out a very feirce, more then she even knew she could do growl"LEAVE MY MAMA ALONE!!"she yells at the top of her lungs"LEAVE HER ALONE!!"She screams
Tanner
Tanner Blackheart: [[uuh -_-"]]
Patman Ballinger: ((Tanner great post lol))
Amara Parmelee: ((It moved me to tears, Tanner. Such powerful words...hahaha))
Tanner Blackheart: [[T_T ur so mean]]
Amara screamed as her hair was caught, the weight of Rico's arm throwing her sideways in the rocky walls. Trickles of blood ran down the side of her face as she heard Arwen's voice. For once, she went back to English. "Arwen, you stay back! I want you nowhere near this!" She pushed herself off the wall, hoping to land a strong blow to Rico's already injured midsection. The roars of defiance and her authoritative stance would speak volumes to the male panther.
Amara Parmelee: ((trans)) Learn well, Rico! This is a pack, not a pride. The elders and leads are to be respected, not taken for granted with they are most convenient for you! You insulted the medics of this family and I will not stand for it! I've tried to be supportive and yet all you're done is behave like an infant!
Patman Ballinger: ((Yea me an amara are friends again it was such an inspiration lol jk
arwen Eiren: (damn i didnt see tanner's post)
Zhin Murakami wakes up, she streches and yawns looking around if she was alone. Zhin touches a spot behind her left ear and a mask morphes out her chaw around her mouth and nose, the last hing she remembered before she felt aslepp, was hearing Amara saying something about a virus.
Tanner had since moved down the stairs, ears plastered on his face and an almost strained, maybe pained expression on his face. He wasn't in pain, however, just fighting... with himself as he moved towards the fighting. His eyes went immidiately to Arwen as he growled out, "If you have your phone... call the pack now... tell them to get their asses here before the den gets smeared with blood..." he says, not seeming to care that his words might scare the child. He turned to Rico and Amara at this point and growled low in his throat, claws out, blood dripping down the sides of his face from the wounds he'd inflicted on himself, crimson eyes getting darker.
arwen Eiren pulls out her pda , pushing a button on it and screams into it top of her lung"RICO AND MAMA MARA TEARING EACH OTHER UP! NEED HELP!THEY WONT STOP FIGHTING!"
Rico moved forward to follow up his hand coming down again clawing at the top of her head again as another burn emerged from his midsection. New claw bloody marks emerging. The stupidest thing someone could do what intervene in a big cat fight. They were fights that couldnt be broken up and could get the one breaking it hurt. He snarled the pain in his stomacheand lower section growing. He roared out bringing his hand up turning waiting for her next attack
Patman Ballinger: ((Trans))I didnt insult the medics. the medics have my respect for the ones I have met. Notice my comments were to you not the medical staff. I said leave me be....LKeave me be........But now you come to fighting. i understand respect but yea anger and worry can make a person abit angry. Now look your cub pleads for you to stop but instead you want to fight.
arwen Eiren heart races as she waits for someone to come help to knock sense into the two fighting. Her little heart raced, she started breathing quickly"stop fightging stop fighting!"she growls , her eyes watering up"DONT HURT MY MOMMY!!"
Zhin Murakami comes downstairs following the fighting noises, she sees Amara and Rico fighting? What the.. she tabs Tanner at his shoulder "What is going on?!" Looking over to Arwen seeing the kid all frighten
Amara kept her body low to the ground before swinging a leg out to trip him. The roars only got louder as if trying to drown out any voice of reason. This was beyond a personal fit for her; this was the natural way of showing her stance on this issue. Wild howls filled every corner of the den as Amara explained herself in a tongue only Rico would understand.
Amara Parmelee: ((trans)) How quickly you forget your words from yesterday. "Fuck it…I'll do what little I can do since no one cares." Of course we cared! We've always cared! But no, you were too stuck up in your own damn impatience to see it! To hell with earlier, that's why I yelled at you yesterday and for your rude remarks, that's why you were shocked!
I'll comfort Arwen after this…after you apologize for trampling over our sacrifices! Mitka was traumatized from her attack and is still in training. Tanner was tortured by the UAC just a few days ago! I was with my wife…I'm sorry it took so long, but you have no right to look down on someone's attempt to help you!
Tanner knew he couldn't let their fight continue much longer... his own fight getting difficult. He couldn't hold the other back much longer if this continued but even considering leaving made it ten times worse to fight the other so he gave up on that idea completely as his eyes narrowed. It was either stop them from fighting... or better yet... knock at least one of them out before all hell broke loose... The moment he felt a tap on his shoulder, however, his eyes narrowed and he wipped around, claws going straight for Zhin's chest as he growls out loudly, eyes getting even darker.
arwen Eiren sdcreaming top her lungs"STOP FIGHTING!"her body shook breathing quickly smelling her mama mara's blood, ears pinned back against her head"no more no more!!FAMILY DONT FIGHT!!!!"She sways as she stands
Rico got off balance from her foot and snarled as he didnt trip fully seeing he was on all fours. He backed away shaking his head as his cheek and stomache bled. His snarls and roars echoeing loudly in return to hers a form of panther speaking that they only could understand
Patman Ballinger: ((Trans)) That noone was directed to you not that it makes my words better. From what I saw you were the only medic with a fucking pda ON!!!. I know tanner was gone !!!
Akiel Martian came running in catching the sight before him, emerald hued eyes shifting already into that darkened feral jade, "..ah 'ell na..", he shook his head, "..this'll na do..", his left mechanical arm raised, coming to be pointed upon Mara and Rico. the arm straightened and that small latch at the palm would open, his right, moved for its respective cerberus gun, "..cover yer ears, Arwen..", he said as he pulled it and raised it high, and ear splitting shot of a fifty cal depleted uranium shell would go off, resonatting the air about them with the sound, Syle's ears flattened agains his head before he growled out, "..S'ENOUGH ALL O' YE'S!!"
Jayde Rasmuson enters and observes the situation at hand.. walking closer to Arwen she puts her hand on the little one's head, a gesture that had become familiar with her. Taking morenote to Amara, Jaydesucked in a deep breath then exhaled.. looking about to the others, emerald glance finally resting 'pon Syle, who was.. fuckin' shit up.. oh shit! Jayde kind of ducked then watched the effect this had..
Zhin Murakami is a little surprised at Tanners move, as his claws dig into her chest she reaches up with her left mechanic hand griping around his wrist, she looks straight into his eyes, purring softly "Shhh..." then she heard Syle yelling and autmaticly ducks pulling Tanner down with her.
Amara let out a last minute reply, her tail hairs flaring angrily as she sounded more like a large angry domestic cat before the sound of Syle's gun shut her up. The blood dripping from her forehead didn't seem to bother her though the immediate ringing in her ears was a different story. Her hands rose to cover her ears from the stinging. "…was deafening us really necessary?" she whimpered.
Amara Parmelee: ((trans)) I was saying goodbye to my lover whom I haven't had a proper sit down with in days! It's not like I just got the message and ran off; we were having a meal…Tanner's PDA was destroyed, and even if he could hear the feed, he was in no position to help!
arwen Eiren hears the gun going off and lets out a scream, and then well between watching her mom fighting , hearing the gun go off, the poor 5 year old fainted
Rico snarls his ears slam down against his head as thee sound of the gun erupts. His cheek and belly were bleeding but his panther communication continued
Patman Ballinger: ((trans))I didnt know you were with her!!! Ok im sorry but I lost alot and It got to me when it seemed like she was dying!!!! So dont turn the whole medic team on me when I spoke to you....And I know tanner wasnt on the line so you were the only one i was speaking to......Now ya daughter needs you more than this fight
Rennat would have winced as he's grabbed by the wrist and pulled down but this wasn't Tanner anymore... this was Rennat who felt no pain. He stared into Zhin's eyes as she shushed him, dark crimson eyes focusing on her and nothing else. He focused his mind on her, blocking out some of the emotions from the other's, dark eyes getting a bit lighter as he gives a bit of an almost pained expression, still fighting the other personality back. He winced quite a bit, tensing against the other at the shot, ears ringing as he growls out.
[12:55] Tanner Blackheart: [[Tanner would have not Rennat would have -_-"]]
Akiel Martian: "When it seem that no one be listenin' ta a worried child n' oi get a text, aye oi think it be..", he said and lowered the gun, wagging it between Rico and Amara with his next words, "..what the fuck be all this about, we're supposed ta be family n' oi walk in ta ye' both tearin' at one another..", he holstered the cerberus gun. Mechanical left arm lowering too as the latch closed, "..what's all this, y'all two have beef, ye' should'na be scrappin' in the den..ye' be scarrin' the wee ones.."
Zhin Murakami slowly straightens up after Syles shoot, her right ear rings and is flaten on the head, she pulls Tanner up wither, her mech hand gripping his right wrist like a bench vice. She continues staring at him, noticing the change in his eyes she purrs softly again "Shhhhhh...."
Amara backed away, moving to check on the collapsed Arwen. "Sweetheart…Arwen…are you alright?" She didn't feel any now pains, so she knew she had not been shot. Ignoring Syle a moment, she mews her final response to Rico. They had reached a relative understanding though no one understood that. She'd gotten the apology she'd been after and the male knew now why she'd been so cross. Not the traditional means of talking things out. "It was in regards to some events concerning yesterday. We've settled it for the most far though. Sometimes, between panthers, it's easier the converse that way. I'm sorry for scaring any of ya…"
Amara Parmelee: ((trans)) If you read your messages again you would have seen my reply "I'm in Madres with Adagio...but I'll head over to the den now." *walks to Arwen* I would never turn the family against you over a petty argument like this, but I'd appreciate if you thought a little better of us.
arwen Eiren had a huge bump on her forehead a bit passedout to respond at the moment, poor kid got the hell scaredout of her
Rico shakes his head free of blood before dipping it in the water. The had worked it out abit and Rico got how he felt out and gave his sorry. He did like having other panthers in the pack to the fact they could talk in their own way but only bad that their language no matter what will look hostile. He dipped his head in the water a sting aas he felt his face stretched when he opened his mouth gettin g a few sips of water. He sighed gave one last few growls before coming uo and sitting on rock
Patman Ballinger: ((Trans)) Im sorry......Its just been a bad run of events.....Hope ovetime this issue heals
Rennat 's heart was racing as he continues to fight back the other personality, the battle getting easier as he focuses on Zhin, though he could still feel the quickly dimming anger coming from the two who'd been fighting but his focus was on Zhin, not seeming bothered by the grip on his wrist, though still seeming to 'wince' every now and then as he continued to fight with the darker personality. Thank god Arwen had managed to get help... or things could have ended badly.
Akiel Martian frowned, shaking his head, "..will take a whole lot more ta scare me than two brawlin' Panthers..", in truth, male panther hybrids worried him, always, Dax was one and Rico another, Panthers were strong cats and possibly the only spcies of Hybrid able to go toe to toe with Syle. The Wolf had size and strength and if it wasnt for that, well. He certainly would have to be worried then, he looked from Amara to Rico, and frowned, he shook his head. Then looked to Tanner, "..oi dun' feel like seein' Rennat ta'day lad..ye' keep 'im locked away nice n' tight.."
Zhin Murakami nods at Syles words, she was glad the fight was over. Zhin holds her gaze straight for Tanners eyes purring deeper as she tightens the grip on his wrist a little more once more she hushes at him "Shhhhhh..." her eyes glowing.
Amara cradled the child in her bruised arms, the blood covered claws long retracted. "It was not out of violence if that explains it further. Just a really primal form of a heart to heart." She sighed as she held Arwen, a long hiss and low growling spoken to Rico again ending in a faint smile. "Still, two Pack members fighting is not something to be encouraged. As the Medic Lead and as an elder, I should know this."
Amara Parmelee: ((trans)) I'd like to help you if you'd just let me…I know how
horrible it can be to be held powerless and captive in a cell…tortured to the point of madness. We can talk another time…when you are ready that is.
Rico listens to the growls and nods his head giving a growl in return. He shakes his head rapidly his hair sending water and blood that dripped from it flying. He stretched his tail swung slowly as he looked around then back to his claws covered in blood and strands of hair. He began to pull at them cleaning them as he sat there
Patman Ballinger: ((trans)) Yea whenevers' fine...But now les both calm down and you can make sure your cubs is ok
arwen Eiren groans her blue eyes flickering opening letting out a yelp hand to her head she starts to cry
Rennat 's ears twitches at Syle's words as he lets out a bitter laugh, "sorry... but Tanner's not in control... hasn't been since shortly after those two morons started fighting... It's not me you should be worried about though... Just be glad i'm around to stop 'the other one' from paying you all a visit..." he lets out, having finally looked away from Zhin, eyes now Rennat's usual crimson color though his heart was still racing as he speeks again, "It may be best if Tanner stays away from the pack for a while... if things like this are going to happen... it's not safe for him or for you... Not till he's got things worked out."
Akiel Martian looked them all over again, sighing, from Amara behind him to Rico, to Zhin and Tanner, "..glad that be over at least..", he said shaking his head, if that was talking, he wondered for a moment, if Keira, with her desire to always have a scrap with Syle, was her way too, of talking? Was there a message to be read in the way, Keira faught? Strange as it would seem, but Amara and Rico, had given Syle something to think on, mayhaps sometimes, later, he would pull one of them aside and ask to learn more on Panther type Hybrids. It could help him with his own, oddly chaotic relationship, "..aye, Mara, ye' should..as should Rico..", his voice was calm, soft, there was no blame being pointed at anyone, "..mayhaps next time, ye' both need a heart ta heart it could be..away from the wee ones eyes?", he certainly wasnt one to go against instinct. After all it was what kept Syle alive this long, instinct, "..oi gotta go, y'all..please..stay safe..", he said before moving, "..aye, dun wanna see that one either..", he said plainly to Tanner before walking out.
Amara immediately tried to calm the child. "It's okay. I'm right here, Arwen." She'd rock back and forth gently to assure Arwen the dust had settled. She'd only nod to Rico, agreeing that the argument of sorts was over. "Rennat…kindly don't call us morons. And if Tanner's mind needs a break from the family and what not for a while, please go ahead and leave. We had no intention of harming tanner nor sparking you to the surface." She groaned at Syle's words, but knew that if her own elders were here, they'd be furious with her.
arwen Eiren buries her head into Amara's shoulder and clings, little tears rolling down her cheeks "no more fighting."
Rico groans as his wound stretch when he lays down. He yawns hanging his leg and arm over into the water and looks around "We need a tree in here" he mumbles before closing his eyes just resting for a moment but nit sleeping
Zhin Murakami looks from Tanner to Syle and back. Slowly she lets go of Tanners wrist, looking down on her chest, she curses as the green was darkened with blood, she did not notice till now. "Dammit, this suit was only a few days old" she grumbles to her self, then she looks up saying loud "Everybody ok so far?"
arwen Eiren looks up" Kitty scratching post?I can buy one uh huhs."
Rennat looks calmly over to Amara, heart beat starting to return to normal as he lets out calmly, "sorry... still a bit tense. We need to keep stuff like that away from Tanner right now... a new, very dangerous, personality has 'appeared' and it's not a friendly one. His name is Tearnn... and he will tear and anyone or anything that's in the vicinity," he explains as he moves to stand slowly, looking to Zhin, "sorry for attacking you."
Tanner Blackheart: [[at anyone]]
Amara shook her head, pausing to pull a cleansing wipe from her bag. "No..no..I know what it looked like but we weren't fighting; we were arguing at best. Mommy's a panther, and that fighting you saw was how panthers argue or voice their opinions. It's not the most civil of sights." She'd hug the girl tightly before attempting to clean her forehead. "Rico, try the beams of the ruined building rather than a tree in here. The city ledges are good also for relaxing." Rennat's description was disturbing at best. "Where did this persona grow from? The UAC attacks…or is it better not to ask?"
That had to be one my most enjoyable RPs to date
The Manticore is my third SHIP. At 180 studs, it is significantly larger than my first two SHIPs. I built the Manticore over an agonizingly long 10 1/2 months.
The Manticore is a heavily-armed orbital death machine with enough firepower to destroy nearly anything produced by humankind. It's main armament is one of the most powerful energy weapons ever produced, colloquially known as the Destructo Beam. The ship also carries two smaller but deadly laser turrets on the roof, a number of smaller turrets, and two fighters.
Fidalgo Bay. General Construction Company's 700 ton capacity crane barge D.B. General. Here to lift the 90ft Northern Marine Yacht Bäden out of the water after it capsized during its launch on sunday night.
NTSB Final Accident Report:
"The newly built yacht Baaden was being launched stern first down the Fidalgo Marina boat ramp in Anacortes, Washington, with eight shipyard personnel on board when it capsized
after entering the water at 2050 on Sunday, May 18, 2014. The yacht was salvaged but was declared a total constructive loss, estimated at $10 million. Three shipyard personnel who were
trapped below decks for up to half an hour were treated for minor cuts and injuries at local hospitals. No pollution was reported.
New World Yacht Builders began construction of the Baaden in December 2011, working from an existing 80-foot-hull mold built in 2002 by Northern Marine. Like other large Northern
Marine yachts, the vessel was custom designed. The 80-foot mold was lengthened in the midsection and stem, the bow was given more flare, and a swim platform was added. The
resulting 85-foot vessel was designated Northern Marine model 8501 and was the first of its kind. New World described the Baaden as having commercial fishing vessel roots in an 85-foot
European-style, luxury, long-range, oceangoing expedition yacht. The builder, the buyer’s representative, and an interior design firm collaborated on the vessel design and styling. Several sister vessels built to the 80-foot-hull design were completed and are in operation.
Due to water damage to interior woodwork, machinery, and electrical systems and expenses associated with repairing the vessel, at the time of this report the Baaden was considered a total constructive loss with an estimated value of $10 million.
Launch team members inspected the launch cradles, dollies, and equipment after the incident and noted that one of the tires on the forward dolly was flat, and witnesses said they saw
bubbles coming from the forward dolly at the time of the launch. The tire likely was damaged during the initial port roll at 2037.
Probable Cause:
The National Transportation Safety Board determines that the probable cause of the capsizing of the yacht Baaden during its initial launch was the vessel’s low margin of stability due to the combined effects of a recording error during the final vessel weigh, which resulted in an incorrect assessment of the vessel’s center of gravity, and an overestimation of the weight of installed ballast."
www.ntsb.gov/investigations/accidentreports/pages/MAB1514...
The fighter bays were an engineering nightmare, because the midsection of the ship has no wall on one side and very little interior support. Its strength comes from Technic frames in both the floor and ceiling, and three layers of solid brick beneath the floor.

The Junkers Ju 52/3m (nicknamed Tante Ju ("Aunt Ju") and Iron Annie) is a German trimotor transport aircraft manufactured from 1931 to 1952. Initially designed with a single engine but subsequently produced as a trimotor it saw both civilian and military service during the 1930s and 1940s. In a civilian role, it flew with over twelve air carriers including Swissair and Deutsche Luft Hansa as an airliner and freight hauler. In a military role, it flew with the Luftwaffe as a troop and cargo transport and briefly as a medium bomber. The Ju 52 continued in postwar service with military and civilian air fleets well into the 1980s.
Design and development
The Ju 52 was similar to the company's previous Junkers W 33, although larger. In 1930, Ernst Zindel and his team designed the Ju 52 at the Junkers works at Dessau. The aircraft's unusual corrugated duralumin metal skin, pioneered by Junkers during World War I, strengthened the whole structure.
The Ju 52 had a low cantilever wing, the midsection of which was built into the fuselage, forming its underside.[1] It was formed around four pairs of circular cross-section duralumin spars with a corrugated surface that provided torsional stiffening. A narrow control surface, with its outer section functioning as the aileron, and the inner section functioning as a flap, ran along the whole trailing edge of each wing panel, well separated from it. The inner flap section lowered the stalling speed and the arrangement became known as the Doppelflügel, or "double wing".[2]
The outer sections of this operated differentially as ailerons, projecting slightly beyond the wingtips with control horns. The strutted horizontal stabilizer carried horn-balanced elevators which again projected and showed a significant gap between them and the stabilizer, which was adjustable in-flight. All stabilizer surfaces were corrugated.
The fuselage was of rectangular section with a domed decking, all covered with corrugated light alloy. There was a port side passenger door just aft of the wings, with windows stretching forward to the pilots' cockpit. The main undercarriage was fixed and divided; some aircraft had wheel fairings, others not. There was a fixed tailskid, or a later tailwheel. Some aircraft were fitted with floats or skis instead of the main wheels.
In its original configuration, designated the Ju 52/1m, the Ju 52 was a single-engined aircraft, powered by either a BMW IV or Junkers liquid-cooled V-12 engine. However, the single-engine model was underpowered, and after seven prototypes had been completed, all subsequent Ju 52s were built with three radial engines as the Ju 52/3m (drei motoren — "three engines"). Originally powered by three Pratt & Whitney R-1690 Hornet radial engines, later production models mainly received 574 kW (770 hp) BMW 132 engines, a licence-built refinement of the Pratt & Whitney design. Export models were also built with 447 kW (600 hp) Pratt & Whitney R-1340 Wasp and 578 kW (775 hp) Bristol Pegasus VI engines. The two wing-mounted radial engines of the Ju 52/3m had half-chord cowlings and in planform view (from above/below) appeared to be splayed outwards, being mounted at an almost perpendicular angle to the tapered wing's sweptback leading edge (in a similar fashion to the Mitsubishi G3M bomber and Short Sunderland; the angled engines on the Ju 52 were intended to make it easier to maintain straight flight should an engine fail, while the others had different reasons). The three engines had either Townend ring or NACA cowlings to reduce drag from the engine cylinders, although a mixture of the two was most common (as can been seen in many of the accompanying photographs), with deeper-chord NACA ducts on the wing engines and a narrow Townend ring on the center engine (which was more difficult to fit a deeper NACA cowl onto, due to the widening fuselage behind the engine). Production Ju 52/3m aircraft flown by Luft Hansa before World War II, as well as Luftwaffe-flown Ju 52s flown during the war, usually used an air-start system to turn over their trio of radial engines, using a common compressed air supply that also operated the main wheels' brakes.

Prewar civil use
In 1932, James A. Richardson's Canadian Airways received (Werknummer 4006) CF-ARM, the sixth ever-built Ju 52/1m. The aircraft, first re-fitted with an Armstrong Siddeley Leopard radial engine and then later with a Rolls-Royce Buzzard and nicknamed the "Flying Boxcar" in Canada,[3][4] could lift approximately three tons and had a maximum weight of 7 tonnes (8 tons). It was used to supply mining and other operations in remote areas with equipment too big and heavy for other aircraft then in use. The Ju 52/1m was able to land on wheels, skis or floats (as were all Ju 52 variants).[5]
Before the nationalisation of the German aircraft industry in 1935, the Ju 52/3m was produced principally as a 17-seat airliner. It was used mainly by Luft Hansa and could fly from Berlin to Rome in eight hours. The Luft Hansa fleet eventually numbered 80 and flew from Germany on routes in Europe, Asia and South America.[citation needed]
Military use 1932–1945
The Colombian Air Force used three Ju 52/3mde bombers equipped as floatplanes during the Colombia-Peru War in 1932–1933. After the war, the air force acquired three other Ju 52mge as transports; the type remained in service until after World War II.
Bolivia acquired four Ju 52s in the course of the Chaco War (1932–1935), mainly for medical evacuation and air supply. During the conflict, the Ju 52s alone transported more than 4,400 tons of cargo to the front.[6]
In 1934, Junkers received orders to produce a bomber version of the Ju 52/3m to serve as interim equipment for the bomber units of the still-secret Luftwaffe until it could be replaced by the purpose designed Dornier Do 11.[7] Two bomb bays were fitted, capable of holding up to 1,500 kg (3,300 lb) of bombs, while defensive armament consisted of two 7.92mm MG 15 machine guns, one in an open dorsal position, and one in a retractable "dustbin" ventral position, which could be manually winched down from the fuselage to protect the aircraft from attacks from below. The bomber could be easily converted to serve in the transport role.[8] The Dornier Do 11 was a failure, however, and the Junkers ended up being acquired in much larger numbers than at first expected, with the type being the Luftwaffe's main bomber until more modern aircraft such as the Heinkel He 111, Junkers Ju 86 and Dornier Do 17 entered into service.[9][10]
The Ju 52 first saw military service in the Spanish Civil War against the Spanish Republic. It was one of the first aircraft delivered to the fraction of the army in revolt in July 1936 as both a bomber and transport. In the former role, it participated in the bombing of Guernica. No more of the bomber variant were built after this war, though it was again used as a bomber during the bombing of Warsaw[11] during the Invasion of Poland of September 1939. The Luftwaffe then relied on the Ju 52 for transport roles during World War II, including paratroop drops.
World War II
In service with Lufthansa, the Ju 52 had proved to be an extremely reliable passenger airplane. Therefore, it was adopted by the Luftwaffe as a standard aircraft model. In 1938, the 7th Air Division had five air transport groups with 250 Ju 52s. The Luftwaffe had 552 Ju 52s at the start of World War II. Even though it was built in great numbers, the Ju 52 was technically obsolete. Between 1939 and 1944, 2,804 Ju 52s were delivered to the Luftwaffe (1939: 145; 1940: 388; 1941: 502; 1942: 503; 1943: 887; and 1944: 379). The production of Ju 52s continued until approximately the summer of 1944; when the war came to an end, there were still 100 to 200 available.
The Ju 52 could carry eighteen fully equipped soldiers, or twelve stretchers when used as an air ambulance. Transported material was loaded and unloaded through side doors by means of a ramp. Air dropped supplies were jettisoned through two double chutes; supply containers were dropped by parachute through the bomb-bay doors, and paratroopers jumped through the side doors. SdKfz 2 kettenkraftrad (half-track motorcycles) and supply canisters for parachute troops were secured under the fuselage at the bomb bay exits and were dropped with four parachutes. A tow coupling was built into the tail-skid for use in towing freight gliders. The Ju 52 could tow up to two DFS 230 gliders.
Heavy losses in combat
The first major operation for the aircraft was in Operation Weserübung, the attack on Denmark and Norway on 9 April 1940. Fifty-two Ju 52s from 1. and 8. Staffel in Kampfgeschwader 1 transported a company of Fallschirmjäger and a battalion of infantry to the northern part of Jutland, and captured the airfield at Aalborg, vital to support the operation in southern Norway. Several hundred Ju 52s were used to transport troops to Norway in the first days of this campaign.
The Netherlands
Later, Ju 52's participated in the attack on the Netherlands on 10 May 1940, where they were deployed in the first large-scale air attack with paratroops in history during the Battle for The Hague. No fewer than 295 Ju 52s were lost in that venture and in other places in the country, due to varying circumstances, among which were accurate and effective Dutch anti-aircraft defences and German mistakes in using soggy airfields not able to support the heavy craft.[12] On 10 May alone, 278 were downed or disabled.
Thus, almost an entire year's production was lost in one day in the Netherlands. The lack of sufficient numbers of aircraft most probably heavily influenced the decision not to invade England following the Battle of Britain.[12]
After the Netherlands
After the campaign in the West, the air transport units were brought up to their pre-Netherlands strength and were assembled at airfields in the Lyon, Lille, and Arras areas in August 1940.[13] Probably this was done using new and repaired aircraft augmented by other transport planes like the FW-200 Condor and the Ju 90.
A Ju 52 approaching Stalingrad, 1942
The next major use of the Ju 52 was in the Balkans campaign, most famously in the Battle of Crete in May 1941. Lightly armed, and with a top speed of only 265 km/h (165 mph) – half that of a contemporary Hurricane – the Ju 52 was very vulnerable to fighter attack and an escort was always necessary when flying in a combat zone. Many Ju 52's were shot down by anti-aircraft guns and fighters while transporting supplies, most notably during the desperate attempt to resupply the trapped German Sixth Army during the final stages of the Battle of Stalingrad in the winter of 1942–1943.
During the North African Campaign, the Ju 52 was the mainstay reinforcement and resupply transport for the Germans, starting with 20 to 50 flights a day to Tunisia from Sicily in November 1942, building to 150 landings a day in early April as the Axis situation became more desperate. The Allied air forces developed a counter-air operation over a two-month period and implemented Operation Flax on 5 April 1943, destroying 11 Ju 52s in the air near Cap Bon and many more during bombing attacks on its Sicilian airfields, leaving only 29 flyable.[14] That began two catastrophic weeks in which more than 140 were lost in air interceptions,[15] culminated on 18 April with the "Palm Sunday Massacre" in which 24 Ju 52s were shot down and another 35 staggered back to Sicily and crash-landed.[16]
The seaplane version, equipped with two large floats, served during the Norwegian Campaign in 1940, and later in the Mediterranean theatre. Some Ju 52's, both floatplanes and landplanes, were also used as minesweepers, known as Minensuch — literally, "mine-search" aircraft in German — fitted with a 14-metre (46 ft) diameter current-carrying degaussing ring under the airframe to create a magnetic field that triggered submerged naval mines and usually given an -"MS" suffix to designate them, as with the similarly equipped Bv 138 MS trimotor flying boat.[17]
Hitler's personal transport
Main article: Hans Baur § Die Fliegerstaffel des Fuehrers
Hitler used a Deutsche Lufthansa Ju 52 for campaigning in the 1932 German election, preferring flying to transport by train. After he became Chancellor of Germany in 1933, Hans Baur became his personal pilot, and Hitler was provided with a personal Ju 52. Named Immelmann II after the World War I ace Max Immelmann, it carried the registration D-2600.[18] As his power and importance grew, Hitler's personal air force grew to nearly 50 aircraft, based at Berlin Tempelhof Airport and made up of mainly Ju 52s, which also flew other members of his cabinet and war staff. In September 1939 at Baur's suggestion, Immelmann II was replaced by a four-engine Focke-Wulf Fw 200 Condor, although Immelman II remained his backup aircraft for the rest of World War II.
Eurasia was the main Chinese Airliner Company in the 1930s and the Ju-52 was their main airliner plane. One of them was commandeered by the Chinese Nationalist Party Government and became Chiang Kai-shek's personal transport.[citation needed]
Postwar use
Various Junkers Ju 52s continued in military and civilian use following World War II. In 1956, the Portuguese Air Force, who was already using the Ju 52s as a transport plane, employed the type as a paratroop drop aircraft for its newly organized elite parachute forces, later known as the Batalhão de Caçadores Páraquedistas. The paratroopers used the Ju 52 in several combat operations in Angola and other Portuguese African colonies before gradually phasing it out of service in the 1960s.[19]
The Swiss Air Force also operated the Ju 52 from 1939 to 1982 when three aircraft remained in operation, probably the last and longest service in any air force.[20] Museums hoped to obtain the aircraft, but they were not for sale.[21] They are still in flying condition and together with a CASA 352 can be booked for sightseeing tours with Ju-Air.[22] During the 1950s the Ju 52 was also used by the French Air Force during the First Indochina War as a bomber. The usage of these Junkers was quite limited.[23]
The Spanish Air Force operated the Ju 52, nicknamed Pava, until well into the 1970s. Escuadrón 721 flying the Spanish-built versions, was employed in training parachutists from Alcantarilla Air Base near Murcia.[24]
Some military Ju 52s were converted to civilian use. For example, British European Airways operated eleven ex-Luftwaffe Ju 52/3mg8e machines, taken over by the RAF, between 1946 and retirement in 1947 on intra-U.K. routes before the Douglas DC-3 was introduced to the airline.[2] French airlines such as Societe de Transports Aeriens (STA) and Air France flew Toucans in the late 1940s and early 1950s.
A Ju 52 and a Douglas DC-3 were the last aircraft to take off from Berlin Tempelhof Airport before all operations ceased there on October 30, 2008.[25]
Other versions
Most Ju 52s were destroyed after the war, but 585 were manufactured after 1945. In France, the machine had been manufactured during the war by the Junkers-controlled Avions Amiot company, and production continued afterwards as the Amiot AAC 1 Toucan. In Spain, Construcciones Aeronáuticas SA continued production as the CASA 352 and 352L. Four CASA 352s are airworthy and in regular use today.
A CASA-built Ju52/3m appears in the opening sequence of the 1968 Richard Burton and Clint Eastwood film Where Eagles Dare.
Maize (/meɪz/ MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taino: mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits.
Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and corn syrup. The six major types of maize are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn. Sugar-rich varieties called sweet corn are usually grown for human consumption as kernels, while field corn varieties are used for animal feed, various corn-based human food uses (including grinding into cornmeal or masa, pressing into corn oil, and fermentation and distillation into alcoholic beverages like bourbon whiskey), and as chemical feedstocks. Maize is also used in making ethanol and other biofuels.
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2014, total world production was 1.04 billion tonnes. Maize is the most widely grown grain crop throughout the Americas, with 361 million metric tons grown in the United States alone in 2014. Genetically modified maize made up 85% of the maize planted in the United States in 2009. Subsidies in the United States help to account for its high level of cultivation of maize and its position as the largest producer in the world.
HISTORY
PRE-COLUMBIAN DEVELOPMENT
Maize is a cultigen; human intervention is required for it to propagate. Whether or not the kernels fall off the cob on their own is a key piece of evidence used in archaeology to distinguish domesticated maize from its naturally-propagating teosinte ancestor. Genetic evidence can also be used to determine when various lineages split.
Most historians believe maize was domesticated in the Tehuacán Valley of Mexico. Recent research in the early 21st century has modified this view somewhat; scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication.
An influential 2002 study by Matsuoka et al. has demonstrated that, rather than the multiple independent domestications model, all maize arose from a single domestication in southern Mexico about 9,000 years ago. The study also demonstrated that the oldest surviving maize types are those of the Mexican highlands. Later, maize spread from this region over the Americas along two major paths. This is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands.
Archaeologist Dolores Piperno has said:
A large corpus of data indicates that [maize] was dispersed into lower Central America by 7600 BP [5600 BC] and had moved into the inter-Andean valleys of Colombia between 7000 and 6000 BP [5000–4000 BC].
— Dolores Piperno, The Origins of Plant Cultivation and Domestication in the New World Tropics: Patterns, Process, and New Developments
Since then, even earlier dates have been published.
According to a genetic study by Embrapa, corn cultivation was introduced in South America from Mexico, in two great waves: the first, more than 6000 years ago, spread through the Andes. Evidence of cultivation in Peru has been found dating to about 6700 years ago. The second wave, about 2000 years ago, through the lowlands of South America.
The earliest maize plants grew only small, 25-millimetre-long (1 in) corn cobs, and only one per plant. In Jackson Spielvogel's view, many centuries of artificial selection (rather than the current view that maize was exploited by interplanting with teosinte) by the indigenous people of the Americas resulted in the development of maize plants capable of growing several cobs per plant, which were usually several centimetres/inches long each. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica; they cooked, ground and processed it through nixtamalization. It was believed that beginning about 2500 BC, the crop spread through much of the Americas. Research of the 21st century has established even earlier dates. The region developed a trade network based on surplus and varieties of maize crops.
Mapuches of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times; however, potato was the staple food of most Mapuches, "specially in the southern and coastal [Mapuche] territories where maize did not reach maturity". Before the expansion of the Inca Empire maize was traded and transported as far south as 40°19' S in Melinquina, Lácar Department. In that location maize remains were found inside pottery dated to 730 ± 80 BP and 920 ± 60 BP. Probably this maize was brought across the Andes from Chile. The presence of maize in Guaitecas Archipelago (43°55' S), the southernmost outpost of pre-Hispanic agriculture, is reported by early Spanish explorers. However the Spanish may have misidentified the plant.
COLUMBIAN EXCHANGE
After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe and introduced it to other countries. Spanish settlers far preferred wheat bread to maize, cassava, or potatoes. Maize flour could not be substituted for wheat for communion bread, since in Christian belief only wheat could undergo transubstantiation and be transformed into the body of Christ. Some Spaniards worried that by eating indigenous foods, which they did not consider nutritious, they would weaken and risk turning into Indians. "In the view of Europeans, it was the food they ate, even more than the environment in which they lived, that gave Amerindians and Spaniards both their distinctive physical characteristics and their characteristic personalities." Despite these worries, Spaniards did consume maize. Archeological evidence from Florida sites indicate they cultivated it as well.
Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. Widespread cultivation most likely began in southern Spain in 1525, after which it quickly spread to the rest of the Spanish Empire including its territories in Italy (and, from there, to other Italian states). Maize had many advantages over wheat and barley; it yielded two and a half times the food energy per unit cultivated area, could be harvested in successive years from the same plot of land, and grew in wildly varying altitudes and climates, from relatively dry regions with only 250 mm (10 in) of annual rainfall to damp regions with over 5,000 mm (200 in). By the 17th century it was a common peasant food in Southwestern Europe, including Portugal, Spain, southern France, and Italy. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially in the form of polenta in Italy.
Names
The word maize derives from the Spanish form of the indigenous Taíno word for the plant, mahiz. It is known by other names around the world.
The word "corn" outside the US, Canada, Australia, and New Zealand refers to any cereal crop, its meaning understood to vary geographically to refer to the local staple. In the United States, Canada, Australia, and New Zealand, corn primarily means maize; this usage started as a shortening of "Indian corn". "Indian corn" primarily means maize (the staple grain of indigenous Americans), but can refer more specifically to multicolored "flint corn" used for decoration.
In places outside the US, Canada, Australia, and New Zealand, corn often refers to maize in culinary contexts. The narrower meaning is usually indicated by some additional word, as in sweet corn, sweetcorn, corn on the cob, baby corn, the puffed confection known as popcorn and the breakfast cereal known as corn flakes.
In Southern Africa, maize is commonly called mielie (Afrikaans) or mealie (English), words derived from the Portuguese word for maize, milho.
Maize is preferred in formal, scientific, and international usage because it refers specifically to this one grain, unlike corn, which has a complex variety of meanings that vary by context and geographic region. Maize is used by agricultural bodies and research institutes such as the FAO and CSIRO. National agricultural and industry associations often include the word maize in their name even in English-speaking countries where the local, informal word is something other than maize; for example, the Maize Association of Australia, the Indian Maize Development Association, the Kenya Maize Consortium and Maize Breeders Network, the National Maize Association of Nigeria, the Zimbabwe Seed Maize Association.
STRUCTURE AND PHYSIOLOGY
The maize plant is often 3 m (10 ft) in height, though some natural strains can grow 13 m (43 ft). The stem is commonly composed of 20 internodes of 18 cm (7 in) length. The leaves arise from the nodes, alternately on opposite sides on the stalk. A leaf, which grows from each node, is generally 9 cm (3+1⁄2 in) in width and 120 cm (3 ft 11 in) in length.
Ears develop above a few of the leaves in the midsection of the plant, between the stem and leaf sheath, elongating by around 3 mm (1⁄8 in) per day, to a length of 18 cm (7 in) with 60 cm (24 in) being the maximum alleged in the subspecies. They are female inflorescences, tightly enveloped by several layers of ear leaves commonly called husks. Certain varieties of maize have been bred to produce many additional developed ears. These are the source of the "baby corn" used as a vegetable in Asian cuisine.
The apex of the stem ends in the tassel, an inflorescence of male flowers. When the tassel is mature and conditions are suitably warm and dry, anthers on the tassel dehisce and release pollen. Maize pollen is anemophilous (dispersed by wind), and because of its large settling velocity, most pollen falls within a few meters of the tassel.
Elongated stigmas, called silks, emerge from the whorl of husk leaves at the end of the ear. They are often pale yellow and 18 cm (7 in) in length, like tufts of hair in appearance. At the end of each is a carpel, which may develop into a "kernel" if fertilized by a pollen grain. The pericarp of the fruit is fused with the seed coat referred to as "caryopsis", typical of the grasses, and the entire kernel is often referred to as the "seed". The cob is close to a multiple fruit in structure, except that the individual fruits (the kernels) never fuse into a single mass. The grains are about the size of peas, and adhere in regular rows around a white, pithy substance, which forms the ear. The maximum size of kernels is reputedly 2.5 cm (1 in). An ear commonly holds 600 kernels. They are of various colors: blackish, bluish-gray, purple, green, red, white and yellow. When ground into flour, maize yields more flour with much less bran than wheat does. It lacks the protein gluten of wheat and, therefore, makes baked goods with poor rising capability. A genetic variant that accumulates more sugar and less starch in the ear is consumed as a vegetable and is called sweet corn. Young ears can be consumed raw, with the cob and silk, but as the plant matures (usually during the summer months), the cob becomes tougher and the silk dries to inedibility. By the end of the growing season, the kernels dry out and become difficult to chew without cooking them tender first in boiling water.
Planting density affects multiple aspects of maize. Modern farming techniques in developed countries usually rely on dense planting, which produces one ear per stalk. Stands of silage maize are yet denser,[citation needed] and achieve a lower percentage of ears and more plant matter.
Maize is a facultative short-day plant and flowers in a certain number of growing degree days > 10 °C (50 °F) in the environment to which it is adapted. The magnitude of the influence that long nights have on the number of days that must pass before maize flowers is genetically prescribed and regulated by the phytochrome system.
Photoperiodicity can be eccentric in tropical cultivars such that the long days characteristic of higher latitudes allow the plants to grow so tall that they do not have enough time to produce seed before being killed by frost. These attributes, however, may prove useful in using tropical maize for biofuels.
Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). DIMBOA is a member of a group of hydroxamic acids (also known as benzoxazinoids) that serve as a natural defense against a wide range of pests, including insects, pathogenic fungi and bacteria. DIMBOA is also found in related grasses, particularly wheat. A maize mutant (bx) lacking DIMBOA is highly susceptible to attack by aphids and fungi. DIMBOA is also responsible for the relative resistance of immature maize to the European corn borer (family Crambidae). As maize matures, DIMBOA levels and resistance to the corn borer decline.
Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to be uprooted by severe winds.
While yellow maizes derive their color from lutein and zeaxanthin, in red-colored maizes, the kernel coloration is due to anthocyanins and phlobaphenes. These latter substances are synthesized in the flavonoids synthetic pathway from polymerization of flavan-4-ols by the expression of maize pericarp color1 (p1) gene which encodes an R2R3 myb-like transcriptional activator of the A1 gene encoding for the dihydroflavonol 4-reductase (reducing dihydroflavonols into flavan-4-ols) while another gene (Suppressor of Pericarp Pigmentation 1 or SPP1) acts as a suppressor. The p1 gene encodes an Myb-homologous transcriptional activator of genes required for biosynthesis of red phlobaphene pigments, while the P1-wr allele specifies colorless kernel pericarp and red cobs, and unstable factor for orange1 (Ufo1) modifies P1-wr expression to confer pigmentation in kernel pericarp, as well as vegetative tissues, which normally do not accumulate significant amounts of phlobaphene pigments. The maize P gene encodes a Myb homolog that recognizes the sequence CCT/AACC, in sharp contrast with the C/TAACGG bound by vertebrate Myb proteins.
The ear leaf is the leaf most closely associated with a particular developing ear. This leaf and above contribute 70% to 75% to 90% of grain fill. Therefore fungicide application is most important in that region in most disease environments.
ABNORMAL FLOWERS
Maize flowers may sometimes exhibit mutations that lead to the formation of female flowers in the tassel. These mutations, ts4 and Ts6, prohibit the development of the stamen while simultaneously promoting pistil development. This may cause inflorescences containing both male and female flowers, or hermaphrodite flowers.
GENETICS
Maize is an annual grass in the family Gramineae, which includes such plants as wheat, rye, barley, rice, sorghum, and sugarcane. There are two major species of the genus Zea (out of six total): Zea mays (maize) and Zea diploperennis, which is a perennial type of teosinte. The annual teosinte variety called Zea mays mexicana is the closest botanical relative to maize. It still grows in the wild as an annual in Mexico and Guatemala.
Many forms of maize are used for food, sometimes classified as various subspecies related to the amount of starch each has:
Flour corn: Zea mays var. amylacea
Popcorn: Zea mays var. everta
Dent corn : Zea mays var. indentata
Flint corn: Zea mays var. indurata
Sweet corn: Zea mays var. saccharata and Zea mays var. rugosa
Waxy corn: Zea mays var. ceratina
Amylomaize: Zea mays
Pod corn: Zea mays var. tunicata Larrañaga ex A. St. Hil.
Striped maize: Zea mays var. japonica
This system has been replaced (though not entirely displaced) over the last 60 years by multivariable classifications based on ever more data. Agronomic data were supplemented by botanical traits for a robust initial classification, then genetic, cytological, protein and DNA evidence was added. Now, the categories are forms (little used), races, racial complexes, and recently branches.
Maize is a diploid with 20 chromosomes (n=10). The combined length of the chromosomes is 1500 cM. Some of the maize chromosomes have what are known as "chromosomal knobs": highly repetitive heterochromatic domains that stain darkly. Individual knobs are polymorphic among strains of both maize and teosinte.
Barbara McClintock used these knob markers to validate her transposon theory of "jumping genes", for which she won the 1983 Nobel Prize in Physiology or Medicine. Maize is still an important model organism for genetics and developmental biology today.
The centromeres have two types of structural components, both of which are found only in the centromeres: Large arrays of CentC, a short satellite DNA; and a few of a family of retrotransposons. The B chromosome, unlike the others, contains an additional repeat which extends into neighboring areas of the chromosome. Centromeres can accidentally shrink during division and still function, although it is thought this will fail if it shrinks below a few hundred kilobase. Kinetochores contain RNA originating from centromeres. Centromere regions can become inactive, and can continue in that state if the chromosome still has another active one.
The Maize Genetics Cooperation Stock Center, funded by the USDA Agricultural Research Service and located in the Department of Crop Sciences at the University of Illinois at Urbana-Champaign, is a stock center of maize mutants. The total collection has nearly 80,000 samples. The bulk of the collection consists of several hundred named genes, plus additional gene combinations and other heritable variants. There are about 1000 chromosomal aberrations (e.g., translocations and inversions) and stocks with abnormal chromosome numbers (e.g., tetraploids). Genetic data describing the maize mutant stocks as well as myriad other data about maize genetics can be accessed at MaizeGDB, the Maize Genetics and Genomics Database.
In 2005, the US National Science Foundation (NSF), Department of Agriculture (USDA) and the Department of Energy (DOE) formed a consortium to sequence the B73 maize genome. The resulting DNA sequence data was deposited immediately into GenBank, a public repository for genome-sequence data. Sequences and genome annotations have also been made available throughout the project's lifetime at the project's official site.
Primary sequencing of the maize genome was completed in 2008. On November 20, 2009, the consortium published results of its sequencing effort in Science. The genome, 85% of which is composed of transposons, was found to contain 32,540 genes (By comparison, the human genome contains about 2.9 billion bases and 26,000 genes). Much of the maize genome has been duplicated and reshuffled by helitrons—group of rolling circle transposons.
In Z. mays and various other angiosperms the MADS-box motif is involved in floral development. Early study in several angiosperm models including Z. mays was the beginning of research into the molecular evolution of floral structure in general, as well as their role in nonflowering plants.
EVOLUTION
As with many plants and animals, Z. mays has a positive correlation between effective population size and the magnitude of selection pressure. Z. m. having an EPS of ~650,000, it clusters with others of about the same EPS, and has 79% of its amino acid sites under selection.
Recombination is a significant source of diversity in Z. mays. (Note that this finding supersedes previous studies which showed no such correlation.)
This recombination/diversity effect is seen throughout plants but is also found to not occur – or not as strongly – in regions of high gene density. This is likely the reason that domesticated Z. mays has not seen as much of an increase in diversity within areas of higher density as in regions of lower density, although there is more evidence in other plants.
Some lines of maize have undergone ancient polyploidy events, starting 11m years ago. Over that time ~72% of polyploid duplicated genes have been retained, which is higher than other plants with older polyploidy events. Thus maize may be due to lose more duplicate genes as time goes along, similar to the course followed by the genomes of other plants. If so - if gene loss has merely not occurred yet - that could explain the lack of observed positive selection and lower negative selection which are observed in otherwise similar plants, i.e. also naturally outcrossing and with similar effective population sizes.
Ploidy does not appear to influence EPS or magnitude of selection effect in maize.
BREEDING
Maize reproduces sexually each year. This randomly selects half the genes from a given plant to propagate to the next generation, meaning that desirable traits found in the crop (like high yield or good nutrition) can be lost in subsequent generations unless certain techniques are used.
Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of the earliest and most successful developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection. Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and the highly successful double cross hybrids using four inbred lines (D. F. Jones c. 1918, 1922). University supported breeding programs were especially important in developing and introducing modern hybrids. By the 1930s, companies such as Pioneer devoted to production of hybrid maize had begun to influence long-term development. Internationally important seed banks such as the International Maize and Wheat Improvement Center (CIMMYT) and the US bank at the Maize Genetics Cooperation Stock Center University of Illinois at Urbana-Champaign maintain germplasm important for future crop development.
Since the 1940s the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic modification have succeeded in increasing output and reducing the need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant.
Tropical landraces remain an important and underutilized source of resistance alleles for for disease and for herbivores. Notable discoveries of rare alleles for this purpose were made by Dao et al 2014 and Sood et al 2014.
GLOBAL PROGRAM
CIMMYT operates a conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by the Drought Tolerant Maize for Africa project.
GENETIC MODIFICATION
Genetically modified (GM) maize was one of the 26 GM crops grown commercially in 2016. The vast majority of this is Bt maize. Grown since 1997 in the United States and Canada, 92% of the US maize crop was genetically modified in 2016 and 33% of the worldwide maize crop was GM in 2016. As of 2011, Herbicide-tolerant maize varieties were grown in Argentina, Australia, Brazil, Canada, China, Colombia, El Salvador, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, the Russian Federation, Singapore, South Africa, Taiwan, Thailand, and the United States. Insect-resistant maize was grown in Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, South Africa, Switzerland, Taiwan, the United States, and Uruguay.
In September 2000, up to $50 million worth of food products were recalled due to the presence of Starlink genetically modified corn, which had been approved only for animal consumption and had not been approved for human consumption, and was subsequently withdrawn from the market.
ORIGIN
Maize is the domesticated variant of teosinte. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between the two is largely controlled by differences in just two genes, called grassy tillers-1 (gt1, A0A317YEZ1) and teosinte branched-1 (tb1, Q93WI2).
Several theories had been proposed about the specific origin of maize in Mesoamerica:
It is a direct domestication of a Mexican annual teosinte, Zea mays ssp. parviglumis, native to the Balsas River valley in south-eastern Mexico, with up to 12% of its genetic material obtained from Zea mays ssp. mexicana through introgression.
It has been derived from hybridization between a small domesticated maize (a slightly changed form of a wild maize) and a teosinte of section Luxuriantes, either Z. luxurians or Z. diploperennis.
It has undergone two or more domestications either of a wild maize or of a teosinte. (The term "teosinte" describes all species and subspecies in the genus Zea, excluding Zea mays ssp. mays.)
It has evolved from a hybridization of Z. diploperennis by Tripsacum dactyloides.
In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum, a related genus. This theory about the origin of maize has been refuted by modern genetic testing, which refutes Mangelsdorf's model and the fourth listed above.
The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931 and the later American Nobel Prize-winner George Beadle in 1932.: 10 It is supported experimentally and by recent studies of the plants' genomes. Teosinte and maize can cross-breed and produce fertile offspring. A number of questions remain concerning the species, among them:
how the immense diversity of the species of sect. Zea originated,
how the tiny archaeological specimens of 3500–2700 BC could have been selected from a teosinte, and
how domestication could have proceeded without leaving remains of teosinte or maize with teosintoid traits earlier than the earliest known until recently, dating from ca. 1100 BC.
The domestication of maize is of particular interest to researchers—archaeologists, geneticists, ethnobotanists, geographers, etc. The process is thought by some to have started 7,500 to 12,000 years ago. Research from the 1950s to 1970s originally focused on the hypothesis that maize domestication occurred in the highlands between the states of Oaxaca and Jalisco, because the oldest archaeological remains of maize known at the time were found there.
Connection with 'parviglumis' subspecies
Genetic studies, published in 2004 by John Doebley, identified Zea mays ssp. parviglumis, native to the Balsas River valley in Mexico's southwestern highlands, and also known as Balsas teosinte, as being the crop wild relative that is genetically most similar to modern maize. This was confirmed by further studies, which refined this hypothesis somewhat. Archaeobotanical studies, published in 2009, point to the middle part of the Balsas River valley as the likely location of early domestication; this river is not very long, so these locations are not very distant. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero.
Doebley was part of the team that first published, in 2002, that maize had been domesticated only once, about 9,000 years ago, and then spread throughout the Americas.
A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley, date back roughly 6,250 years; the oldest ears from caves near Tehuacan, Puebla, 5,450 B.P.
Maize pollen dated to 7,300 B.P. from San Andres, Tabasco, on the Caribbean coast has also been recovered.
As maize was introduced to new cultures, new uses were developed and new varieties selected to better serve in those preparations. Maize was the staple food, or a major staple – along with squash, Andean region potato, quinoa, beans, and amaranth – of most pre-Columbian North American, Mesoamerican, South American, and Caribbean cultures. The Mesoamerican civilization, in particular, was deeply interrelated with maize. Its traditions and rituals involved all aspects of maize cultivation – from the planting to the food preparation. Maize formed the Mesoamerican people's identity.
It is unknown what precipitated its domestication, because the edible portion of the wild variety is too small, and hard to obtain, to be eaten directly, as each kernel is enclosed in a very hard bivalve shell.
In 1939, George Beadle demonstrated that the kernels of teosinte are readily "popped" for human consumption, like modern popcorn. Some have argued it would have taken too many generations of selective breeding to produce large, compressed ears for efficient cultivation. However, studies of the hybrids readily made by intercrossing teosinte and modern maize suggest this objection is not well founded.
SPREADING TO THE NORTH
Around 4,500 ago, maize began to spread to the north; it was first cultivated in what is now the United States at several sites in New Mexico and Arizona, about 4,100 ago.
During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for the new crop.
In 2005, research by the USDA Forest Service suggested that the rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels, which are very sensitive to environmental changes.
CULTIVATION
PLANTING
Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As a plant that uses C4 carbon fixation, maize is a considerably more water-efficient crop than plants that use C3 carbon fixation such as alfalfa and soybeans. Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July", although modern hybrids generally exceed this growth rate. Maize used for silage is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine. Although it is grown mainly in wet, hot climates, it has been said to thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop.
Maize was planted by the Native Americans in hills, in a complex system known to some as the Three Sisters. Maize provided support for beans, and the beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. This method was replaced by single species hill planting where each hill 60–120 cm (2 ft 0 in–3 ft 11 in) apart was planted with three or four seeds, a method still used by home gardeners. A later technique was "checked maize", where hills were placed
1 m (40 in) apart in each direction, allowing cultivators to run through the field in two directions. In more arid lands, this was altered and seeds were planted in the bottom of 10–12 cm (4–4+1⁄2 in) deep furrows to collect water. Modern technique plants maize in rows which allows for cultivation while the plant is young, although the hill technique is still used in the maize fields of some Native American reservations. When maize is planted in rows, it also allows for planting of other crops between these rows to make more efficient use of land space.
In most regions today, maize grown in residential gardens is still often planted manually with a hoe, whereas maize grown commercially is no longer planted manually but rather is planted with a planter. In North America, fields are often planted in a two-crop rotation with a nitrogen-fixing crop, often alfalfa in cooler climates and soybeans in regions with longer summers. Sometimes a third crop, winter wheat, is added to the rotation.
Many of the maize varieties grown in the United States and Canada are hybrids. Often the varieties have been genetically modified to tolerate glyphosate or to provide protection against natural pests. Glyphosate is an herbicide which kills all plants except those with genetic tolerance. This genetic tolerance is very rarely found in nature.
In the midwestern United States, low-till or no-till farming techniques are usually used. In low-till, fields are covered once, maybe twice, with a tillage implement either ahead of crop planting or after the previous harvest. The fields are planted and fertilized. Weeds are controlled through the use of herbicides, and no cultivation tillage is done during the growing season. This technique reduces moisture evaporation from the soil, and thus provides more moisture for the crop. The technologies mentioned in the previous paragraph enable low-till and no-till farming. Weeds compete with the crop for moisture and nutrients, making them undesirable.
HARVESTING
Before the 20th century, all maize harvesting was by manual labour, by grazing, or by some combination of those. Whether the ears were hand-picked and the stover was grazed, or the whole plant was cut, gathered, and shocked, people and livestock did all the work. Between the 1890s and the 1970s, the technology of maize harvesting expanded greatly. Today, all such technologies, from entirely manual harvesting to entirely mechanized, are still in use to some degree, as appropriate to each farm's needs, although the thoroughly mechanized versions predominate, as they offer the lowest unit costs when scaled to large farm operations. For small farms, their unit cost can be too high, as their higher fixed cost cannot be amortized over as many units.[citation needed]
Before World War II, most maize in North America was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover) and corn binders, which are reaper-binders designed specifically for maize (for example, Video on YouTube). The latter produce sheaves that can be shocked. By hand or mechanical picker, the entire ear is harvested, which then requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs, and these whole ears are a sufficient form for some livestock feeding use. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine and store it in bins. The combine with a corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil. The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter the machinery. The combine separates the husk and the cob, keeping only the kernels.
When maize is a silage crop, the entire plant is usually chopped at once with a forage harvester (chopper) and ensiled in silos or polymer wrappers. Ensiling of sheaves cut by a corn binder was formerly common in some regions but has become uncommon. For storing grain in bins, the moisture of the grain must be sufficiently low to avoid spoiling. If the moisture content of the harvested grain is too high, grain dryers are used to reduce the moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases (propane or natural gas) and electricity to power the blowers.
PRODUCTION
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2018, total world production was 1.15 billion tonnes, led by the United States with 34.2% of the total (table). China produced 22.4% of the global total.
UNITED STATES
In 2016, maize production was forecast to be over 380 million metric tons (15 billion bushels), an increase of 11% over 2014 American production. Based on conditions as of August 2016, the expected yield would be the highest ever for the United States. The area of harvested maize was forecast to be 35 million hectares (87 million acres), an increase of 7% over 2015. Maize is especially popular in Midwestern states such as Indiana, Iowa, and Illinois; in the latter, it was named the state's official grain in 2017.
STORAGE
Drying is vital to prevent or at least reduce mycotoxin contamination. Aspergillus and Fusarium spp. are the most common mycotoxin sources, but there are others. Altogether maize contaminants are so common, and this crop is so economically important, that maize mycotoxins are among the most important in agriculture in general.
USES
HUMAN FOOD
Maize and cornmeal (ground dried maize) constitute a staple food in many regions of the world. Maize is used to produce cornstarch, a common ingredient in home cooking and many industrialized food products. Maize starch can be hydrolyzed and enzymatically treated to produce syrups, particularly high fructose corn syrup, a sweetener; and also fermented and distilled to produce grain alcohol. Grain alcohol from maize is traditionally the source of Bourbon whiskey. Corn flour is used to make cornbread and other baked products.
In prehistoric times Mesoamerican women used a metate to process maize into ground cornmeal, allowing the preparation of foods that were more calorie dense than popcorn. After ceramic vessels were invented the Olmec people began to cook maize together with beans, improving the nutritional value of the staple meal. Although maize naturally contains niacin, an important nutrient, it was not bioavailable without the process of nixtamalization. The Maya used nixtamal meal to make varieties of porridges and tamales. The process was later used in the cuisine of the American South to prepare corn for grits and hominy.
Maize is a staple of Mexican cuisine. Masa (cornmeal treated with limewater) is the main ingredient for tortillas, atole and many other dishes of Central American food. It is the main ingredient of corn tortilla, tamales, pozole, atole and all the dishes based on them, like tacos, quesadillas, chilaquiles, enchiladas, tostadas and many more. In Mexico the fungus of maize, known as huitlacoche, is considered a delicacy.
Coarse maize meal is made into a thick porridge in many cultures: from the polenta of Italy, the angu of Brazil, the mămăligă of Romania, to cornmeal mush in the US (or hominy grits in the South) or the food called mieliepap in South Africa and sadza, nshima, ugali and other names in other parts of Africa. Introduced into Africa by the Portuguese in the 16th century, maize has become Africa's most important staple food crop. These are commonly eaten in the Southeastern United States, foods handed down from Native Americans, who called the dish sagamite.
Maize can also be harvested and consumed in the unripe state, when the kernels are fully grown but still soft. Unripe maize must usually be cooked to become palatable; this may be done by simply boiling or roasting the whole ears and eating the kernels right off the cob. Sweet corn, a genetic variety that is high in sugars and low in starch, is usually consumed in the unripe state. Such corn on the cob is a common dish in the United States, Canada, United Kingdom, Cyprus, some parts of South America, and the Balkans, but virtually unheard of in some European countries. Corn on the cob was hawked on the streets of early 19th-century New York City by poor, barefoot "Hot Corn Girls", who were thus the precursors of hot dog carts, churro wagons, and fruit stands seen on the streets of big cities today.
Within the United States, the usage of maize for human consumption constitutes only around 1/40th of the amount grown in the country. In the United States and Canada, maize is mostly grown to feed livestock, as forage, silage (made by fermentation of chopped green cornstalks), or grain. Maize meal is also a significant ingredient of some commercial animal food products.
NUTRITIONAL VALUE
Raw, yellow, sweet maize kernels are composed of 76% water, 19% carbohydrates, 3% protein, and 1% fat (table). In a 100-gram serving, maize kernels provide 86 calories and are a good source (10–19% of the Daily Value) of the B vitamins, thiamin, niacin (but see Pellagra warning below), pantothenic acid (B5) and folate (right table for raw, uncooked kernels, USDA Nutrient Database). In moderate amounts, they also supply dietary fiber and the essential minerals, magnesium and phosphorus whereas other nutrients are in low amounts (table).
Maize has suboptimal amounts of the essential amino acids tryptophan and lysine, which accounts for its lower status as a protein source. However, the proteins of beans and legumes complement those of maize.
FEED AND FODDER FOR LIVESTOCK
Maize is a major source of both grain feed and fodder for livestock. It is fed to the livestock in various ways. When it is used as a grain crop, the dried kernels are used as feed. They are often kept on the cob for storage in a corn crib, or they may be shelled off for storage in a grain bin. The farm that consumes the feed may produce it, purchase it on the market, or some of both. When the grain is used for feed, the rest of the plant (the corn stover) can be used later as fodder, bedding (litter), or soil amendment. When the whole maize plant (grain plus stalks and leaves) is used for fodder, it is usually chopped all at once and ensilaged, as digestibility and palatability are higher in the ensilaged form than in the dried form. Maize silage is one of the most valuable forages for ruminants. Before the advent of widespread ensilaging, it was traditional to gather the corn into shocks after harvesting, where it dried further. With or without a subsequent move to the cover of a barn, it was then stored for weeks to several months until fed to the livestock. Today ensilaging can occur not only in siloes but also in silage wrappers. However, in the tropics, maize can be harvested year-round and fed as green forage to the animals.
CHEMICALS
Starch from maize can also be made into plastics, fabrics, adhesives, and many other chemical products.
The corn steep liquor, a plentiful watery byproduct of maize wet milling process, is widely used in the biochemical industry and research as a culture medium to grow many kinds of microorganisms.
Chrysanthemin is found in purple corn and is used as a food coloring.
BIO-FUEL
"Feed maize" is being used increasingly for heating; specialized corn stoves (similar to wood stoves) are available and use either feed maize or wood pellets to generate heat. Maize cobs are also used as a biomass fuel source. Maize is relatively cheap and home-heating furnaces have been developed which use maize kernels as a fuel. They feature a large hopper that feeds the uniformly sized maize kernels (or wood pellets or cherry pits) into the fire.[citation needed]
Maize is increasingly used as a feedstock for the production of ethanol fuel. When considering where to construct an ethanol plant, one of the site selection criteria is to ensure there is locally available feedstock. Ethanol is mixed with gasoline to decrease the amount of pollutants emitted when used to fuel motor vehicles. High fuel prices in mid-2007 led to higher demand for ethanol, which in turn led to higher prices paid to farmers for maize. This led to the 2007 harvest being one of the most profitable maize crops in modern history for farmers. Because of the relationship between fuel and maize, prices paid for the crop now tend to track the price of oil.
The price of food is affected to a certain degree by the use of maize for biofuel production. The cost of transportation, production, and marketing are a large portion (80%) of the price of food in the United States. Higher energy costs affect these costs, especially transportation. The increase in food prices the consumer has been seeing is mainly due to the higher energy cost. The effect of biofuel production on other food crop prices is indirect. Use of maize for biofuel production increases the demand, and therefore price of maize. This, in turn, results in farm acreage being diverted from other food crops to maize production. This reduces the supply of the other food crops and increases their prices.
Maize is widely used in Germany as a feedstock for biogas plants. Here the maize is harvested, shredded then placed in silage clamps from which it is fed into the biogas plants. This process makes use of the whole plant rather than simply using the kernels as in the production of fuel ethanol.
A biomass gasification power plant in Strem near Güssing, Burgenland, Austria, began in 2005. Research is being done to make diesel out of the biogas by the Fischer Tropsch method.
Increasingly, ethanol is being used at low concentrations (10% or less) as an additive in gasoline (gasohol) for motor fuels to increase the octane rating, lower pollutants, and reduce petroleum use (what is nowadays also known as "biofuels" and has been generating an intense debate regarding the human beings' necessity of new sources of energy, on the one hand, and the need to maintain, in regions such as Latin America, the food habits and culture which has been the essence of civilizations such as the one originated in Mesoamerica; the entry, January 2008, of maize among the commercial agreements of NAFTA has increased this debate, considering the bad labor conditions of workers in the fields, and mainly the fact that NAFTA "opened the doors to the import of maize from the United States, where the farmers who grow it receive multimillion-dollar subsidies and other government supports. ... According to OXFAM UK, after NAFTA went into effect, the price of maize in Mexico fell 70% between 1994 and 2001. The number of farm jobs dropped as well: from 8.1 million in 1993 to 6.8 million in 2002. Many of those who found themselves without work were small-scale maize growers."). However, introduction in the northern latitudes of the US of tropical maize for biofuels, and not for human or animal consumption, may potentially alleviate this.
COMMODITY
Maize is bought and sold by investors and price speculators as a tradable commodity using corn futures contracts. These "futures" are traded on the Chicago Board of Trade (CBOT) under ticker symbol C. They are delivered every year in March, May, July, September, and December.
ORNAMENTAL AND OTHER USES
Some forms of the plant are occasionally grown for ornamental use in the garden. For this purpose, variegated and colored leaf forms as well as those with colorful ears are used.
Corncobs can be hollowed out and treated to make inexpensive smoking pipes, first manufactured in the United States in 1869.
An unusual use for maize is to create a "corn maze" (or "maize maze") as a tourist attraction. The idea of a maize maze was introduced by the American Maze Company who created a maze in Pennsylvania in 1993. Traditional mazes are most commonly grown using yew hedges, but these take several years to mature. The rapid growth of a field of maize allows a maze to be laid out using GPS at the start of a growing season and for the maize to grow tall enough to obstruct a visitor's line of sight by the start of the summer. In Canada and the US, these are popular in many farming communities.
Maize kernels can be used in place of sand in a sandboxlike enclosure for children's play.
Stigmas from female maize flowers, popularly called corn silk, are sold as herbal supplements.
Maize is used as a fish bait, called "dough balls". It is particularly popular in Europe for coarse fishing.
Additionally, feed corn is sometimes used by hunters to bait animals such as deer or wild hogs.
UNITED STATES USAGE BREAKDOWN
The breakdown of usage of the 12.1-billion-bushel (307-million-tonne) 2008 US maize crop was as follows, according to the World Agricultural Supply and Demand Estimates Report by the USDA.In the US since 2009/2010, maize feedstock use for ethanol production has somewhat exceeded direct use for livestock feed; maize use for fuel ethanol was 5,130 million bushels (130 million tonnes) in the 2013/2014 marketing year.A fraction of the maize feedstock dry matter used for ethanol production is usefully recovered as DDGS (dried distillers grains with solubles). In the 2010/2011 marketing year, about 29.1 million tonnes of DDGS were fed to US livestock and poultry. Because starch utilization in fermentation for ethanol production leaves other grain constituents more concentrated in the residue, the feed value per kg of DDGS, with regard to ruminant-metabolizable energy and protein, exceeds that of the grain. Feed value for monogastric animals, such as swine and poultry, is somewhat lower than for ruminants.
HAZARDS
PELLAGRA
When maize was first introduced into farming systems other than those used by traditional native-American peoples, it was generally welcomed with enthusiasm for its productivity. However, a widespread problem of malnutrition soon arose wherever maize was introduced as a staple food. This was a mystery, since these types of malnutrition were not normally seen among the indigenous Americans, for whom maize was the principal staple food.
It was eventually discovered that the indigenous Americans had learned to soak maize in alkali — water (the process now known as nixtamalization) — made with ashes and lime (calcium oxide) since at least 1200–1500 BC by Mesoamericans. They did this to liberate the corn hulls, but (unbeknownst to natives or colonists) it coincidentally liberates the B-vitamin niacin, the lack of which was the underlying cause of the condition known as pellagra.
Maize was introduced into the diet of non-indigenous Americans without the necessary cultural knowledge acquired over thousands of years in the Americas. In the late 19th century, pellagra reached epidemic proportions in parts of the southern US, as medical researchers debated two theories for its origin: the deficiency theory (which was eventually shown to be true) said that pellagra was due to a deficiency of some nutrient, and the germ theory said that pellagra was caused by a germ transmitted by stable flies. A third theory, promoted by the eugenicist Charles Davenport, held that people only contracted pellagra if they were susceptible to it due to certain "constitutional, inheritable" traits of the affected individual.
Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high lysine maize and the promotion of a more balanced diet have also contributed to its demise. Pellagra still exists today in food-poor areas and refugee camps where people survive on donated maize.
ALLERGY
Maize contains lipid transfer protein, an indigestible protein that survives cooking. This protein has been linked to a rare and understudied allergy to maize in humans. The allergic reaction can cause skin rash, swelling or itching of mucous membranes, diarrhea, vomiting, asthma and, in severe cases, anaphylaxis. It is unclear how common this allergy is in the general population.
MYCOTOXINS
Fungicide application does not reduce fungal growth or mycotoxin dramatically, although it can be a part of a successful reduction strategy. Among the most common toxins are those produced by Aspergillus and Fusarium spp. The most common toxins are aflatoxins, fumonisins, zearalenone, and ochratoxin A. Bt maize discourages insect vectors and by so doing it dramatically reduces concentrations of fumonisins, significantly reduces aflatoxins, but only mildly reduces others.
ART
Maize has been an essential crop in the Andes since the pre-Columbian era. The Moche culture from Northern Peru made ceramics from earth, water, and fire. This pottery was a sacred substance, formed in significant shapes and used to represent important themes. Maize was represented anthropomorphically as well as naturally.
In the United States, maize ears along with tobacco leaves are carved into the capitals of columns in the United States Capitol building. Maize itself is sometimes used for temporary architectural detailing when the intent is to celebrate the fall season, local agricultural productivity and culture. Bundles of dried maize stalks are often displayed along with pumpkins, gourds and straw in autumnal displays outside homes and businesses. A well-known example of architectural use is the Corn Palace in Mitchell, South Dakota, which uses cobs and ears of colored maize to implement a mural design that is recycled annually. Another well-known example is the Field of Corn sculpture in Dublin, Ohio, where hundreds of concrete ears of corn stand in a grassy field.
A maize stalk with two ripe ears is depicted on the reverse of the Croatian 1 lipa coin, minted since 1993.
WIKIPEDIA
Taken in lower Manhattn in March of 2008. Elisha in Billikid's rockership. Elisha looks determined. This time he will not fail .
Elisha and Bocvana departed earth armed with a .357 magnum, silver bullets, garlic, Holy Water and a wooden stake. This time Kam the Alien would be killed dead.
As they entered space Elisha and Bocvana turned off their cloaking device so as to attract the attention of Kam and her UFO. Sure enough they were picked up and drawn into the hull of the giant UFO. Kam was there to greet them.
Kam said hello and remarked that they could be a threesome. We played along with it and said sure, why not. So she set us all up in a big bedroom where she thought the action would take place.
Kam was still in the form of the mannequin Kathleen and looked like a million bucks. When she was naked she looked absolutely gorgeous. Too bad she would be dead in a few seconds.
I pulled out the .357 and pumped six silver bullets dipped in Holy Water and rubbed with garlic into her midsection. That did it. She spurted lots of blood and fell to the floor dead.
Before she could revive herself Bocvana and I drove a wooden stake into her heart. Red blood gushed from the wound.
Just to make sure that she would not come back to life we placed a garlic garland around her neck. We also had some peeled pieces of garlic which we inserted into her mouth and shoved up her butt and vagina.
Then we looked for a way out and back to our spaceship. We were actually in the cockpit when who should appear yet again, but Kam.
Oh my God I said to Bocvana, we are done for, she is neither a werewolf nor a Vampire.
Kam said she was neither a Vampire nor a werewolf because those creatures were not natural to her planet. They both came from the earth. She said that we had only momentarily knocked her out but now she said she was back.
She smiled and said that she enjoyed the experience of being almost dead. It was thrilling according to her. She again called me a jerk and said that Bocvana was a fool to even go along with me. Then she let us go. Her last remark before we took off was... " Elisha I'll see you soon" .
March 5, 2008.
This photo was taken in a dressing room at a Ross Dress for Less store in Orlando on Sunday, June 29. It was a busy evening for Joni. . . .
It started with dinner at a nearby Carrabba's with the wife as documented in the previous posted photo. After dinner, Joni drove back to her time share condo to drop off the wife and do some tidying up by putting on some jewelry items she had inexplicably neglected to put on before going out to dinner, possibly a warning of oncoming senility on her part. One can zoom in on this photo and see that she is wearing a necklace and bracelets on her wrists. These items are conspicuously absent in the previous posted portrait photo in which Joni was happily dining on her Chicken Parmiajoni earlier in the evening at Carrabba's. Also added on this return trip, but not really visible, were a pair of earrings. (Seriously, Joni, how do you forget to put on earrings before going out anywhere en femme??? Didn't you feel naked?)
Once properly accessorized, Joni then headed out to Orlando proper to drop in on one of her favorite LGBTQ haunts in the "Big O", as Orlando likes to bill itself. Sunday night in Orlando is not to be confused with a typical Friday or Saturday night in the clubs and bars, which are usually packed. Sunday evenings are far more sedate, as there was a much smaller crowd and there were opportunities to actually flirt with the relaxed bartenders, who normally don't have time to engage in verbal foreplay because they are usually overwhelmed serving beers and mixing and pouring drinks non-stop to the thirsty throngs who flaunt the local fire code's rules about maximum occupancy. Not so on Sunday nights when the vibe is far more subdued. So flirt away Joni did, as she enjoyed the rare opportunity to claim an open seat at the bar, especially since Joni wasn't attracting much attention from any of the younger studs who were in attendance.
Thus it was appropriate that at some point, Joni was approached by another older female patron who identified herself as a local woman from nearby Kissimmee. Oddly, she asked Joni if she came to this club often as this was only the third time she herself had been there despite living in the Orlando area for the past 15 years. Joni advised her that she was a tourist, but that she usually came here a few times any week that Joni was in town, which was once or twice a year since the wife and Joni maintained time shares in Orlando. Joni made a point of mentioning the wife as well as the fact that Joni was checking out in the morning and returning to South Carolina so as to subtly discourage the woman from entertaining any notions about hooking up with Joni for the night, which Joni sensed was a primary motive for the woman to approach Joni as she did. . . .
Not that the woman was unattractive, because she wasn't. Dressed in an ankle length floral skirt with a lacy white top, Joni would guess the woman was approximately 50 years old, give or take a few years. She was slightly paunchy in her midsection, which one might expect with a woman of that age, but she still had a pretty face and was displaying rather impressive cleavage. Joni sensed she was on the make and probably divorced, and probably lonely. I suspect she may have thought the same about Joni.
Furthermore, she didn't seem to care that Joni was a TG, and when Joni initially spoke in her non-feminine voice, her only reaction was to note that Joni didn't sound like someone from South Carolina. Indeed, we wound up having a pleasant conversation for about 20 minutes during which the woman never acknowledged or alluded to the fact that Joni was a TG. I guess one can call that acceptance; a nice thing in an increasingly non-accepting world.
During the course of our conversation, Joni confirmed the woman's suspicions that Joni was not a South Carolinian, but that she was originally a New Yorker by way of New Jersey who had retired to South Carolina. In turn, she advised Joni that she was also from New York, having grown up and lived upstate near Plattsburgh up by the Canadian border on the way to Montreal. She had moved south to Florida for employment, and was still working for a living. Jon and the woman commiserated that they both appeared to be out of place in this venue because they were clearly older than the vast majority of the patrons, but she said she still liked it because it was "fun". She suggested that the next time Joni is in town, she should try "Disney Springs", which has an adult themed nightclub on the Disney property which attracts an older crowd. Hmmm. . . . Frankly, Joni is quite skepticaI about that recommendation, but I suppose dancing with Mickey and Minnie might be fun! Hell, Joni might explore it first in drab and then give it a try. Maybe. . . Eventually, we parted ways which was good because it was already past 10:30 pm and Joni had one last item of business to attend to before she called it a night. She wanted to satisfy her urge to do some femme shopping, and she knew just the place to go - Ross "Dress for Less"!
Yes! Joni was going to a Ross "Dress for Less" late on a Sunday night to shop! What a concept! But shouldn't a store like Ross be closed on a late Sunday night, one might wonder? The short answer is "Yes", because everything else in Orlando was closed other than gas stations and convenience stores like Wa-wa. However, Joni's alter ego discovered this oddity by accident on the first night after he and the wife checked in late on Thursday evening and he went out looking for a grocery store to buy some food items to tide them over for their long weekend stay in Orlando. The alter ego had assumed that he could find a Publix or at least a Walmart that was open late, or at least until 10:00 p.m.
Once upon a time, it was common to find all-night Walmarts in various locations in and around Orlando, or in places like Myrtle Beach, as well as in parts of New Jersey. The rationale in those days was that these large stores kept their lights and air and heating systems operating overnight because they had work crews working to re-stock their shelves overnight, so it only made sense to keep the doors open all night with at least one cashier and open register during the overnight period to generate some extra sales revenue. The all-night stores were actually a great convenience to people whose jobs required them to work until late at night or the early morning hours, or for someone like Joni who would show up at 2:30 a.m. after a night of clubbing to scour the otherwise deserted cosmetic aisles or the women's hosiery department for new femme supplies without feeling embarrassed in the presence of other shoppers, or even the work crews, all of whom were trained by Walmart as a matter of corporate policy to be polite and accommodating to members of the LGTBQ community, and others similarly situated.
However, that apparently all ended as a result of the Pandemic. Nowadays, it is difficult to find any kind of store that stays open past ten o'clock, including a Walmart. Where Joni lives in South Carolina, most businesses and stores are closed by 8:00 p.m. when they literally roll up the sidewalks. . . . but this was Orlando, a hot international tourist destination. Surely, something would be open? Right?? . . . . WRONG!!! The alter ego thought he found a glimmer of hope when he drove by a shopping center in Kissimmee with a large Publix store visible from the highway with about 20 cars parked in the lot. It was almost 11:00 p.m. He was ecstatic after having driven around for about an hour searching vainly for an open store. He pulled into the lot and parked the car and walked up to the front door of Publix only to discover that this Publix was closed and had been closed since 9:00 p.m. So why are there so many cars in the parking lot? What gives?? That's when he saw a woman walk out of the adjacent store with a shopping bag. It was a Ross "Dress for Less". Walking over to the front door, he could see that there were plenty of people inside the store, shopping and working. This was definitely odd, he thought to himself. "It must be a special Thursday night thing.", he rationalized, until his unbelieving eyes spotted the store hours posted on one of the doors. Incredibly, this Ross store stayed open until midnight every night, seven nights a week! . . . Including Sundays!! . . . . Incredible!!!
He walked off and returned back to the resort condo empty-handed that night , but he was determined to alert Joni so she could take advantage of this unique shopping opportunity before the weekend was over. Joni was not a regular shopper at any Ross store, but she has had some notable good luck shopping at other Ross stores on occasion in various locations in the past.
So on the night in question, Joni returned to the Ross store and sure enough, it was open and quite busy. Joni only had less than an hour before closing to peruse the racks, but working fast, she identified 5 items to take into the changing room to try on as prospective purchases. She found a few winners; two pencil skirts, one in denim, and a floral print blouse and proceeded to the register where she got on a long line and waited for at least 20 minutes before she reached one of the three registers. The store was not only open, but it was busy as hell! The sum total for the three items was just a bit more than $40.00, and Joni was quite happy to "Dress for Less" during her midnight shopping spree! Indeed, the clock struck 12 well before she exited the store, and there were still many others waiting on line to reach the cashiers.
The attached photo was taken in the dressing room before Joni started trying on different items. From her smile, one can sense that Joni felt she was about to strike gold. . . .
"John D. Leitch" & the Tugs "Point Valour" & "Glenada"
The 2 tugs have been opening the slip while the Risley is reopening the channel through the ice for
the Leitch who has been waiting to dock at Thunder Bay Terminals. But has been unable to get near there due to Ice Fields being blown into that part of the Bay and closing the channels cut by the Breakers.
This unique Great Lakes self-unloading bulk carrier was built by Port Weller Dry Docks, St. Catharines, Ont., as Hull #41. She was christened Canadian Century for Upper Lakes Group, Inc., Toronto, Ont., on April 15, 1967 by Mrs. G. E. Gathercole, wife of the Chairman of the Hydro Electric Power Commission of Ontario. The name paid tribute to the 100th anniversary of Canada’s confederation.
At the time of her launch, the vessel was the largest capacity self-unloading vessel on the Great Lakes. Her squared hull design reduced wasted space thus increasing her tonnage, however her very tall wheelhouse and forward accommodation block gave her the distinction of being known as the “little bank building that floats.”
The Canadian Century’s original self-unloading system consisted of a single, center line conveyor belt gravity system with a 300-ton reclaimer feeding a bucket/hopper elevator system leading to a forward-mounted 250 foot discharge boom. The reclaimer consisted of 2 auger screws, each 26 feet long and 7 feet high. As they would turn, the cargo would be forced forward to the bucket elevator system. It could discharge at a rate of up to 4,000 tons per hour. Due to the technological advances in self-unloading systems, the Canadian Century’s bucket elevator system was replaced in 1975/76 with a modern loop belt elevator system capable of discharging cargo at a rate of up to 4,572 tons per hour. The discharge boom can be swung 95 degrees to port or starboard.
The vessel is powered by a Burmeister & Wain type 574 VT2F 160 diesel engine rated at 7,394 b.h.p. at 115 r.p.m. burning intermediate grade 180 fuel driving a controllable pitch propeller, giving the vessel a service speed of 14.5 knots. She is equipped with a 1,000 horsepower bowthruster. Her enormous single hold is fed by 22 hatches. She can carry 25,700 tons at maximum Seaway draft of 26 feet and is capable of carrying 31,600 tons at her maximum mid-summer draft of 29 feet 4 inches. Other capacities include 465 tons of fuel oil, 75 tons of diesel oil, 186 tons of potable water, and 17,348 tons of water ballast.
In December 2001, Canadian Century entered Port Weller Dry Docks for a mid-life refit. The $25-million (C) refit was similar to the work that the shipyard completed on Canada Steamship Lines’ CSL Tadoussac the winter before. The bow and stern sections remained intact, along with most of the main deck. The cargo hold and the rest of the midsection were replaced with a new, larger cargo hold and a one-belt self-unloading system with a flat tank top. When it returned to service in May of 2002, it not only carried more cargo, but could operate more efficiently through the increased use of technology.
The Century was built specifically to accommodate Upper Lakes Group’s first contract to carry coal for Ontario Hydro. During her first season of operation, she made 63 trips delivering coal totaling 1.7 million tons. On Dec. 8, 1967, she set a Welland Canal coal record by carrying 28,283 tons from Conneaut, Ohio, to Dofasco at Hamilton, Ont. June 18, 1969 saw the Canadian Century load a Conneaut, Ohio, record of 31,081 tons of coal for Ontario Hydro’s Lambton Generating Station at Courtright, Ont. In her early years, she would sail to Sept Isles, Que., to rendezvous with her former fleet mate Ontario Power to transfer coal loaded aboard the latter vessel at Sydney, Nova Scotia, for delivery to Nanticoke, Ont. The Canadian Century carried her first load of taconite ore pellets in 1986 when she loaded 25,427 tons at Pointe Noire, Que., for Hamilton, Ont. The vessel has carried cargoes of salt from ports such as Goderich, Ont., and Fairport, Ohio. She has also carried the odd cargo of grain products.
In her later years, the Canadian Century sailed under the management of Seaway Marine Transport, St. Catharines, Ont., a partnership of Algoma Central and Upper Lakes Group.
On March 23, 2001, the vessel was honored in the traditional Top Hat ceremony recognizing the passing of the first upbound vessel through the Welland Canal for the 2001 navigation season.
In 2002, the vessel was renamed John D. Leitch, honoring the chairman of the Upper Lakes Group. On February 25, 2011, a formal statement was issued announcing the sale of the privately owned Upper Lakes fleet and their associated interest in Seaway Marine Transport to the Algoma Central Corporation. On April 15, 2011, Algoma announced that the John D. Leitch would retain her name.

NTSB Final Accident Report:
"The newly built yacht Baaden was being launched stern first down the Fidalgo Marina boat ramp in Anacortes, Washington, with eight shipyard personnel on board when it capsized after entering the water at 2050 on Sunday, May 18, 2014.
The yacht was salvaged but was declared a total constructive loss, estimated at $10 million. Three shipyard personnel who were trapped below decks for up to half an hour were treated for minor cuts and injuries at local hospitals. No pollution was reported.
New World Yacht Builders began construction of the Baaden in December 2011, working from an existing 80-foot-hull mold built in 2002 by Northern Marine. Like other large Northern
Marine yachts, the vessel was custom designed. The 80-foot mold was lengthened in the midsection and stem, the bow was given more flare, and a swim platform was added. The
resulting 85-foot vessel was designated Northern Marine model 8501 and was the first of its kind. New World described the Baaden as having commercial fishing vessel roots in an 85-foot European-style, luxury, long-range, oceangoing expedition yacht. The builder, the buyer’s representative, and an interior design firm collaborated on the vessel design and styling. Several sister vessels built to the 80-foot-hull design were completed and are in operation.
Due to water damage to interior woodwork, machinery, and electrical systems and expenses associated with repairing the vessel, at the time of this report the Baaden was considered a total constructive loss with an estimated value of $10 million.
Launch team members inspected the launch cradles, dollies, and equipment after the incident and noted that one of the tires on the forward dolly was flat, and witnesses said they saw bubbles coming from the forward dolly at the time of the launch. The tire likely was damaged during the initial port roll at 2037.
Probable Cause:
The National Transportation Safety Board determines that the probable cause of the capsizing of the yacht Baaden during its initial launch was the vessel’s low margin of stability due to the combined effects of a recording error during the final vessel weigh, which resulted in an incorrect assessment of the vessel’s center of gravity, and an overestimation of the weight of installed ballast."

GUNDAM BZ DEFENDER
This is my fourth Gundam MOC, however this one is not from any Gundam continuity this is a custom Gundam based on my new double jointed mech frame design. If you made it to Brickfete you saw this before my internet audience did! Thanks to all the other mech builders for their suggestions and criticisms which resulted in a more poseable Lego Mobile suit frame for this MOC. This Gundam MOC stands tall at 15 inches – 3 inches taller than my usual mech / leader class transformer size and is equipped with a midsection cockpit for its pilot. He is very poseable! Enjoy rate and comment!
Pls also check out my YouTube video for more details on this MOC:
This is a new building I’ve not seen before found out a bit of info on it:
One Blackfriars is. 50 storey building, which is central London’s tallest residential tower since the Barbican. Containing 273 private flats, it was designed by Iain Simpson and features a distinctive curved, double-skin glass facade containing a continuous envelope of winter gardens. No expense has been spared; the building features 5,476 pieces of individually curved glass panels to ensure the facade looks as smooth and elegant as possible. Inspired by a 1950s vase, the building bulges outwards towards its midsection. Simpson says his building differs from other London skyscrapers due to its dynamic and asymmetrical form, which plays on the reflection of light from the ground and river below.
Most of the flats have been sold but if you have £12.5m to spare there is still time to reserve a three-bedroom apartment on the 42nd floor.
This is the outfit I wore during a recent poetry reading: The Nicole by Nicole Miller dress is something I found at JCPenney, along with a skirt of a similar pattern. I think the animal print is so striking (*purrr*).
The belt is something that's been in my closet for a long while; I can't remember exactly when or where I bought it, but it does go well with this dress, not to mention keeps the dress in place (flyaway at the midsection is so unsightly when you're out on the town).
This wavy red hair has steadily become my favorite, if not one of my favorites, especially after someone at a support group mentioned to me that I look better as a redhead than as a blonde. (Hmmm...)
Detail of the midsection of a fine Swamp Bay (Persea palustris) specimen growing in sandy soil next to the parking lot.
A close relative of the Avocado (P. americana), it's a member of the Lauraceae (Laurel Family) and one of the Carolinas' characteristic barrier-island tree species. As its name suggests, it's often a wetland associate, though here and elsewhere it seems to tolerate sandy soil near coastal dunes as well.
And like another relative, the Old World's true Laurel or Bay Tree (Laurus nobilis), Swamp Bay has simple, entire-margined, and delightfully aromatic leaves.
This image nicely shows the plant's mature bark, on the largest trunk visible here.
