A pair of Red-eyed Damselflies ovipositing. The blue male keep hold of the back of the green female's head using claspers at the end of his abdomen. This prevents other males mating with her, and he can also pull her clear of the water if she slips under the surface (it often happens.). The female is depositing her eggs directly into the water, which concludes the entirety of the parenting process! It will be at least a year until the nymphs that develop from the fertilized eggs and grow through several moults, will emerge as new damselflies. The adult forms survive only for a matter of days or weeks.
Meanwhile, a pair of male Common Blue damselflies lurk nearby. Unpaired male damselflies are commonly seen loitering around ovipositing damselflies, and even the much larger, dragonflies. I have no idea why they do this, as there is no possibility of them mating with other species.
Das ist keine Luftbildaufnahme des Amazonas oder Orinoco sondern der Grund eines Teiches der leergepumpt wurde. Wo nach dem abpumpen erst nur Schlamm zu sehen war, erhebt sich die Natur wie ein Phönix aus der Asche und schafft hier neuem Leben Platz. Die Grundlage ist der überaus nährstoffreiche Teichschlamm, welcher sich auch zum Düngen bestens eignet. Diese erst wenige Tage alten Pflänzchen bilden einen Anblick, als ob ich einen Urwald von oben fotografiert hätte und das Restwasser, welches immer noch abläuft, erscheint wie ein grosser Fluss. Die Täuschung beim Betrachten ist erstaunlich. Man kann Wellen und Sandbänke, Palmen und Sumpfland sehen. Wie eine Miniaturwunderwelt.
Jungle
This is not an aerial photo of the Amazon or Orinoco but the bottom of a pond that has been pumped out. Where only mud could be seen after pumping, nature rises like a phoenix from the ashes and creates space for new life. The basis is the extremely nutrient-rich pond mud, which is also ideally suited for fertilization. These little plants, which are only a few days old, look as if I had photographed a jungle from above and the remaining water, which is still running off, appears like a large river. The deception when looking at it is amazing. You can see waves and sandbars, palm trees and marshland. Like a miniature wonderland.
Best to view in large size!
October 1998. I visited my friend Pam in Vancouver. A colony of Yellow Jackets had built their nest outside the sliding glass doors that opened onto the sundeck of her condo. What a structure! It was enormous, at least 15-20 inches in diameter, its paper surface an intricately patterned maze of whorls and flow lines.
I set up my tripod with the 105mm macro lens. Fall is the season when most wasp stings occur, because the young, fertilized queens abandon the colony around this time and fly off to mate and then find a protected place to spend the winter. While the social order begins to break down - no more young to feed, no purpose - food sources become scarce. None of the workers, nor the old queen, will survive winter. They are easily agitated at this time of year; don't mess with them.
For some reason, I wasn't stung. I moved slowly but worked fast. Wasps create the "paper" for their nests by chewing plant fibres and mixing them with their saliva, and it was obvious that the materials for their nest came from many different sources. The wood rail on Pam's deck showed long scrape marks about the width of a wasp's mandibles. Functionality aside, I thought their nest was one of the most beautiful natural objects I had ever seen.
Photographed in Vancouver, BC, on Fujichrome Provia 100; scanned from the original slide. The nest was in deep shade, so exposure was approximately 8 seconds at f/22-32 (with lots of bracketing).

Wikipedia: A dovecote or dovecot, doocot (Scots) or columbarium is a structure intended to house pigeons or doves. Dovecotes may be free-standing structures in a variety of shapes, or built into the end of a house or barn. They generally contain pigeonholes for the birds to nest. Pigeons and doves were an important food source historically in the Middle East and Europe and were kept for their eggs and dung.
The oldest dovecotes are thought to have been the fortress-like dovecotes of Upper Egypt and the domed dovecotes of Iran. In these regions the droppings were used by farmers for fertilization. Pigeon droppings were also used for leather tanning and making gunpowder.
In some cultures, particularly Medieval Europe, the possession of a dovecote was a symbol of status and power and was consequently regulated by law. Only nobles had this special privilege, known as droit de colombier.
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches (modified labella) of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily.
The outer margins of the wings are strongly and irregularly dentate, excavated and angulated. The upper side of the wings has a bright orange ground colour, decorated with brown marks and light spots on the edge. The reverse is marbled with brown. Folded, the butterfly looks like a dead leaf. The hindwings have on the reverse side a white spot usually in the shape of C.
The sexual dimorphism is slight and concerns the intensity of the coloration, the silhouette and the size, the male having a wingspan of 22 to 24 mm. and the female of 25 to 26 mm. The seasonal dimorphism is more marked: the first generation ( hutchinsoni form, May-June) has the upperside fawn orange and the underside brown-gold and the hindwing bears distally a broad dark red-brown area in which is situated a row of light brown hastate spots, the underside is dark, being either unicolorous or prominently marmorated. , while the second generation (form c-album (July, in autumn and spring after overwintering) has a more reddish upper and dark brown underside (ground-colour is less bright). In the summer-form the wings are less dentate, and the hindwing has a narrow dark submarginal band, near which stands a row of light lunules proximally bordered by a band of brown arcs; the underside is of a paler colour, being less distinctly — sometimes, however, very prominently — marmorated and shaded.
Comma butterflies have a polyandrous mating system where females mate with multiple males to receive the necessary amount of sperm to fertilize their eggs. The polyandrous female distributes her matings equally over her lifetime, so males' mating success increases proportionally to their lifespan. The mating success of both sexes is correlated to the duration of an individual's life, so no difference in mortality rates is observed between males and females.
Unlike female host plant preference, egg mass is not shown to be sex-linked. Instead, egg mass is most likely controlled by additive autosomal genes, where the egg sizes of offspring are intermediate compared to its parents. The type of host plant chosen during the larval stage is not correlated with their offspring's egg mass, indicating that egg size is not related to fitness.
Best if viewed large. This fella is well known about town. He is a member of the local Dahlia Association (don't know it's real name) and even has his own concoction for fertilizing dahlias. I'd say it works.
More wonder in the front yard, just watering the few plants left in my milkweed patch. Suddenly all these little green things started leaping out of nowhere, at least a hundred it seemed. I thought they were little teeny flies till I kneeled for closer inspection. Grasshopper nymphs! Kid you not, half the size or less of my baby fingernail. I managed to run for the camera to try and catch them, but they really scattered quickly. At my first look at this pebble, it was densely covered with their little bodies. Here only a few remain. As for the teeny white "dust" specs next to the rock, I don't know but I'm guessing egg shells.
Gleaned from the Web, in case you wanted to know: "The lifecycle of a grasshopper starts with the egg stage. During summer, female grasshoppers lay fertilized eggs in egg pods, usually in more than 10. Each pod consists of roughly 10-300 rice-shaped eggs, depending on the species. During the autumn and winter seasons, for almost 10 months, the eggs remain dormant (under the sand or leaf litter). Again during the next spring or early summer, the eggs hatch into nymphs, the offspring.
"The Nymph is the second stage in the lifecycle. Here, the young nymphs feed on succulent, soft plant foliage immediately after hatching. They are tiny look-alikes of the adult, except they are light-colored and without their wings.
"During this stage, the developing insects shed their skin (metamorphosis) five to six times. The process is called molting. The nymph stage lasts about 5-10 days, based on the species and the weather conditions."
You might remember this exact same thing happened in my yard a year ago, approximately the same exact place in the flower bed. I actually just copied/pasted what I wrote then.,. because what I wrote was perfect.
The annual salmon migration to the spawning grounds takes place throughout the month of September and first half October. The Chinook and Coho Salmon that have been feeding in our Great Lakes since they migrated downriver after hatching are returning upriver to spawn and create a new generation by laying eggs and fertilizing them to fulfill their purpose in life.
This salmon is trying to negotiate the fish ladder installed in Bowmanville Creek on its way to spawn.
Thank you to everyone that visits, favs and leaves comments. You are all very much appreciated.
The Lusitano, also known as the Pure Blood Lusitano or PSL (Puro Sangue Lusitano), is a Portuguese horse breed. Horses were known to be present on the Iberian Peninsula as far back as 20,000 BC, and by 800 BC the region was renowned for its war horses. The fame of the horses from Lusitania goes back to the Roman Age, which attributed its speed to the influence of the West wind, who was considered capable of fertilizing the mares. When the Muslims invaded Iberia in 711 AD, they brought Arabian horses with them that were crossed with the native horses, developing a horse that became useful for war, dressage and bull fighting. The Portuguese horse was named the Lusitano, after the word Lusitania, the ancient Roman name for the region that modern Portugal occupies. There are four main breed lineages within the breed today, and characteristics differ slightly between each line.
Lusitanos can be any solid color, although they are generally gray, bay or chestnut. Horses of the Alter Real strain are always brown. Members of the breed are of Baroque type, with convex facial profiles, heavy muscling, intelligent and willing natures, with agile and elevated movement. Originally bred for war, dressage and bullfighting, Lusitanos are still used today in the latter two. They have competed in several Olympics and World Equestrian Games as part of the Portuguese and Spanish dressage teams.
ENGLISH
Campanula medium, common name Canterbury bells, is an annual or biennial flowering plant of the genus Campanula, belonging to the family Campanulaceae. In floriography, it represents gratitude, or faith and constancy.
Campanula medium reaches approximately 60–80 cm (24–31 in) in height. This biennial herbaceous plant forms rosettes of leaves in the first year, stems and flowers in the second one. The stem is erect, robust, reddish-brown and bristly hairy. The basal leaves are stalked and lanceolate to elliptical and 12–15 cm (5–6 in) long with serrated leaf edge. The upper leaves are smaller, lanceolate and sessile, almost embracing the stem.
The flowers are arranged in a racemose inflorescence of extremely long-lasting blooms. These attractive bell-shaped flowers are short-stalked, large and hermaphroditic, with different shades of violet-blue or rarely white. The corolla has five fused petals with lightly bent lobes (known as a coronate flower type).
The flowering period extends from May to July in the Northern Hemisphere. The flowers are either self-fertilized (autogamy) or pollinated by insects such as bees and butterflies (entomogamy).[1] The seeds ripen from August to September and are dispersed by gravity alone (barochory).
Campanula medium originates in southern Europe. It is naturalized in most of European countries and in North America and it is widely cultivated for its beautiful flowers.
It grows on stony, rocky and bushy slopes, at an altitude of 0–1,500 metres (0–4,921 ft) above sea level.

It is the largest member of the water lily family. The lily pads are up to 8 feet across and the large white to pink blooms are very fragrant, having a sweet pineapple-like scent on the first day of is two day lifecycle. Only blooming for a few days, the flowers will open at night on the first day being white, then turn pink after being fertilized.
Giant Waterlily is one of two species in this genus and is not viviparous, meaning that the seeds do not develop before they detach from the parent plant. It is the largest member of the water lily family. The lily pads are up to 8 feet across and the large white to pink blooms are very fragrant, having a sweet pineapple-like scent on the first day of is two day lifecycle. Only blooming for a few days, the flowers will open at nighttime on the first day being white. When they open on the second night, they will be purple-red color and will have lost their scent.
Its leaves are rounded and upturned. It is supported by a ribbed underside and anchored to a submerged stalk, with the leaf floating on the water surface. The stalks can be up to 26 feet long and in nature will embed themselves in the lake or river bottom. This rapid growing plant can expand by up to 20 inches per day. While the upper surface has water repellent properties, the underside is protected from herbivorous fish by its sharp spines. Air becomes trapped between the ribs on the underside, which keeps it afloat.
Fascinating tidbit ... Beetles attracted by the scent of the white flower the first night are trapped the next day when it closes. Then the plant changes from female to male and produces pollen. Opening the next night as an unscented, red-purple flower, the beetle which is now coated in pollen, is released and flies to the next white flower and repeats the pollination process there.
It is suitable for large water gardens only and grown as an annual without winter protection. It grows best in quiet water as the backwaters of large rivers. In tropical zones, it can be grown as a perennial, where it will grow best when anchored in an organically rich loam. The water temperatures must remain above 75 degrees for the plant to remain as a perennial.
1' to 3' of quiet, still waters are the best growing conditions. In locations that have currents running through, or are subject to heavy winds should be avoided. Seed can be started indoors in containers that are placed in water that has constant temperatures above 80 degrees. Outdoor planting can be done in late spring, when the water temperatures have reached a minimum of 70 degrees. The plants that are grown in containers are placed into the still waters in their containers. In areas that experience cooler winters, the containers can be removed and stored in a greenhouse in anticipation of the next outdoor season.

Probably a black-tailed jackrabbit, that's what we get around here. The gold club is closed, along with all other non-essential businesses, but the local rabbits were doing their best to keep the golf course looking good... both mowing and fertilizing!
Wildhorse Golf Course, Davis, Ca. April, 2020.
The virgin queen started. This is her wedding flight - she will meet drones, and , when fertilized find a lair to hibernate.
Her mother (the old queen) died already, her folk will starve to death.
Leaves are a marvel. They act as a natural mulch, suppressing weeds while fertilizing soil as they break down. They serve as a habitat for small wildlife that overwinter under the fallen leaves. They absorb carbon dioxide and release oxygen which we humans and animals need to live.
On top of all that, they are the palette for not only seasonal changes in their color, but they can become the surface for all sorts of marvelous natural decorations.
A farmer fertilizes his land in front of windmill 'De Wingerdse Molen' in Bleskensgraaf, a small community near Dordrecht. This mill is a poldermill, used for the polder of Wijngaarden (also small village nearby). Unique about this mill is that it is situated some distance away from the polder it drains, which is not seen very often. It still is able to drain it thanks to a network of little ditches, and bosoms that lead from the polder to the mill.
The mill has a flight of 28,20 metres. The year it was built is unknown, but it is known that the mill was raised 1,30 metres in 1872, and that new wicks were installed in 1935. It was functional until 1973.
Next to this mill two other mills are located: a small windmill 'Het Haantje', used by the millers son as a playing/learning mill. This mill is only 3 metres high. And a 'tjasker mill' that is also able to drain water. A tjasker is a Frysian type of mill, and is very simple looking, but is functional.

After moving to Arkansas, we learned that the winter, which everyone told us was very light, was in fact, not. While it is shorter than the east coast, the cold is nowhere near light. Plus, the added humidity and windy nature if the great plains mean it gets pretty chilly out here in winter. An unforeseen consequence of this is a lack of opportunity to practice my bird photography in winter. One cool thing about our LA apartment was a balcony that I painstakingly converted into a garden oasis for the local birds.
I had no shortage of candidates to practice my bird photography. We used to have jays, doves, finches, hummers, and even occasional hawks that used to drop by, but unfortunately, I haven’t had the same luck in Arkansas. The few birds that drop by seems very timid and would fly away as soon as they see any movement or if they hear any sound. It’s a bit different from LA, where the hummingbirds used to divebomb each other around us while we were watering the plants. To honor that memory, I am dedicating today's image of the tiny Anna’s hummingbird doing his bit to fertilize the daisies.
everyone was rushing to work and ended up in the fog ;o))) However, what I didn't realize in the dark that I was standing in
a fertilized field ;o(((
alle beeilten sich zur Arbeit und endeten im Nebel ;o))) Was ich jedoch im Dunkeln nicht bemerkte, das ich mich auf einem gedüngten Feld befand ;o(((

One of the flowers in my backyard that I really enjoy. I wish there were more. Time to fertilize I guess.
A close-up of a tiger lily flower from my wife's flower garden. The six anthers, dark in color, hang from the filaments that support them. They are the pollen-producing organs. The reddish stigma, which catches pollen, is at the end of the style, the structure that pollen tubes grow through, so that fertilization can occur.
Isn't God a great artist? Thanks for looking.
Her mate has arrived and grasped her by the neck as she lowers herself (with his help) into the water to deposit the fertilized eggs on the plants stem below the water line.
This non-native plant is both a striking wildflower and an important part of agricultural practice. The flower itself is a compound affair, with multiple units growing off a common short stem. The name ‘birdsfoot’ refers to the seed pods that grow behind the flower later in the season, and which resemble bird’s feet when clustered on the common stem. The ‘trefoil’ part of the name refers to the fact that three flowers are on each side of the short stem.
This flower shows part of what I find striking about them: a brilliant red flower bud morphs into an equally brilliant yellow flower. These are best photographed in early morning light or half-light, as here (you can see the dew still on the flower) thanks to the brilliance of the yellow.
It contributes to the work of farming in a few ways that are distinctive and unique. The plant is a legume - it produces seeds in pods that develop behind the flower. The roots of the trefoil host a bacteria that generates and attracts nitrogen, thus making this a self-fertilizing plant. As well, it reduces bloating in livestock, and reduces gas emissions. It is rich in protein, and so an environmentally effective way to feed farm animals in hay or pasture.
I worked on a farm in my late teens, and the sight of fields of trefoil at a certain point in the flowering stage is something I will never forget. This was an isolated wild plant growing along an overgrown field and its fence line, and it still seemed striking.
I cannot wait for the summer.
The greatest amount of activity we saw among the frogs was, unfortunately, not in a protected area but in a flooded ditch. Here is a pair of Illinois Chorus Frogs engaged in amplexus, where the male seeks to fertilize eggs after they are released by the female.
Cycadeen - Palmfarne im Botanischen Garten der HHU Düsseldorf.
Cycadeen (Palmfarne) - lebende Fossilien
Die Cycadeen haben ihren deutschen Namen durch die oft palmenartige Wuchsform und die eingerollten Blätter oder Blattfiedern. Sie gehören jedoch weder zu den Palmen noch zu den Farnen. Vielmehr bilden sie unter den Samenpflanzen eine eigene Klasse (Cycadop-sida), die u.a. mit den Koniferen und den Ginkgo- Gewächsen zu den Nacktsamern (Gymnospermae) gezählt wird. Da sie schon seit dem Perm (ca. 300-250 Mio. Jahre) vorkommen, werden sie auch als „lebende Fossilien" bezeichnet.
Der Stamm der Palmfarne kann eine Höhe von bis zu 15 m erreichen; bei einigen Arten entwickelt er sich jedoch nur unterirdisch und knollenartig. In seinem Zentrum wird ein stärkehaltiges Mark gebildet, das als „Sago" (gewonnen aus Arten der Gattung Cycas) zur Verdickung von Lebensmitteln Verwendung findet. Die gefiederten Laubblätter sind schraubig angeordnet und bilden einen Schopf. Sie sind sehr hart, haben meist eine sehr dicke Cuticula und eingesenkte Spaltöffnungen und sind dadurch gut an die Bedingungen ihres Lebensraums angepasst.
Bei vielen Arten findet man in „koralloiden" . Wurzeln Cyanobakterien („Blaualgen"), die Luftstickstoff fixieren können und an die Pflanzen abgeben.
Lange Zeit wurde angenommen, dass die Cycadeen durch den Wind bestäubt werden; bei genaueren Untersuchungen stellten sich jedoch Käfer und andere Insekten als Bestäuber heraus. Die Befruchtung erfolgt in der Regel erst einige Monate nach der Bestäubung, und hierbei zeigt sich eine Besonderheit für Samenpflanzen, die die Cycadeen nur mit Ginkgo biloba gemeinsam haben: Es werden begeißelte Spermazellen, gebildet. Die Spermatozoiden der Palmfarne sind mit bis zu 0,4 mm die größten, die man aus dem Pflanzen- und Tierreich kennt.
Die Blüten der Palmfarne sind diözisch verteilt, d.h. männliche und weibliche Blüten befinden sich auf verschiedenen Pflanzen und bilden dort Zapfen aus. Die weiblichen Zapfen können sich zu einer enormen Größe entwickeln und bilden auch ohne Befruchtung (!) leuchtend gefärbte Samen aus.
Cycads - cycads in the botanical garden of the HHU Düsseldorf.
Cycads (cycads) - living fossils
The cycads got their German name from the often palm-like growth form and the rolled-up leaves or leaflets. However, they belong neither to the palm trees nor to the ferns. Rather, they form a class of their own among the seed plants (Cycadop-sida), which, together with the conifers and the ginkgo plants, is counted among the naked seeds (Gymnospermae). Since they have been around since the Permian (approx. 300-250 million years), they are also referred to as "living fossils".
The trunk of the cycads can reach a height of up to 15 m; in some species, however, it develops only underground and tuber-like. A starchy pith is formed in its center, which is used as "sago" (obtained from species of the genus Cycas) to thicken food. The pinnate leaves are arranged helically and form a tuft. They are very hard, usually have a very thick one Cuticula and sunken stomata and are therefore well adapted to the conditions of their habitat.
In many species, cyanobacteria ("blue-green algae") are found in "coralloid" roots, which can fix atmospheric nitrogen and release it to the plants.
For a long time it was thought that cycads were pollinated by the wind; however, closer examination revealed beetles and other insects as pollinators. Fertilization usually takes place a few months after pollination, and this reveals a special feature for seed plants that the cycads only have in common with Ginkgo biloba: Flagellate sperm cells are formed. At up to 0.4 mm, the spermatozoids of cycads are the largest known from the plant and animal kingdom.
The flowers of the cycads are dioecious, i.e. male and female flowers are on different plants and form cones there. The female cones can develop to an enormous size and produce brightly colored seeds even without fertilization (!).
Mushroom gnats look for particular types of fungi on which to lay their eggs. Aristolochia arborea imitate one of these mushrooms perfectly, even under the microscope the surface of the false mushroom is almost indistinguishable from the real thing. Aristolochia has to make such a perfect impression or the mushroom gnats won’t land to lay eggs. When they do they slide off the slippery surface, get caught in the trap behind the false mushroom, and pollinate the flower.
Aristolochia double-crosses its pollinators. They fertilize it and receive nothing in exchange, no pollen, no nectar, not even a place to lay their eggs. Only the plant benefits from this one-sided relationship.
This rose is growing in the garden that runs out to the street. I forget its name, and I don't think it even bloomed last year. I had high hopes for it, but I have bad luck with roses. I will fertilize it and protect it better from disease and insects this summer.
Heavy winds yesterday flipped over the unfolding Amazonica Lily pads. Check out its detailed construction. This is what makes it possible for them to hold a person afloat on the surface!
The Amazonica is the largest member of the water lily family. The lily pads are up to 8 feet across and the large fragrant white to pink blooms have a sweet pineapple-like scent on the first day of its two day lifecycle. The flowers will open at night on the first day being white, then turn pink after being fertilized.
The lily pads are up to 8 feet across and are supported by a ribbed underside and anchored to a submerged stalk allowing the leaf to float on the surface. These stalks which can be up to 26 feet long aembed themselves in a lake or river bottom. This rapid growing plant can expand by up to 20 inches per day. While the upper surface has water repellent properties, the underside is protected from herbivorous fish by its sharp spines. Air becomes trapped between the ribs on the underside, which keeps it afloat.

Hembra de Orthetrum trinacria devorando a otra hembra de Diplacodes lefebvrii. La hembra de Diplacodes comenzó a expulsar paquetes de huevos (ver final de su abdomen junto al tallo) en el momento en que empezó a ser comida.
Algunos estudiosos consultados explican este fenómeno como un mecanismo para seguir perpetuando la especie lanzándo los huevos al exterior (se desconoce si estaban fecundados o no).
No lo tengo nada claro. Se aceptan sugerencias.

I have it not clear. Suggestions welcome.
All the lessons of history in four sentences: Whom the gods would destroy, they first make mad with power. The mills of God grind slowly, but they grind exceedingly small. The bee fertilizes the flower it robs. When it is dark enough, you can see the stars.

Hazel catkins are the male flowers of the hazel tree appearing as long, yellowish, pendulous clusters. They are one of the earliest signs of spring. These catkins release pollen into the wind to fertilize the small, inconspicuous red female flowers, which eventually develop into hazelnuts by autumn. Hazel catkins play an essential role in early-season pollination and provide a valuable food source for insects like bees when few other plants are in bloom.

Winged carpenter ants, or alates, are the reproductive members of the colony. They swarm in warm weather, usually in spring or early summer, to mate. After mating in mid-air, males die, and fertilized females shed their wings to start new colonies.
My yellow holiday cactus. When I bought it, it was covered with dozens of buds on very short stems. I knew it had been over fertilized and holiday cacti do not like to be moved when in bloom. So, the buds all fell off. The plant will perform much better next year.
"Meanwhile...." I grabbed this stand-up shot showing its pretty colors.

Flower - Flor
Filogenéticamente, la flor es una rama modificada. La flor considerada típica es la de las angiospermas, y está constituida por cuatro verticilos (“pisos”) de hojas modificadas (antofilos). Recorriendo el eje de la flor desde su base hacia el extremo, encontramos sucesivamente:
Los sépalos son los que envuelven a las otras hojas en las primeras fases de desarrollo, cuando la flor es sólo un capullo. También evitan en las especies entomófilas, que los insectos accedan al néctar sin pasar por los estambres y estigmas. Los sépalos se sueldan en muchos casos para formar una estructura acopada que justifica el nombre de cáliz (copa) con que se designa al conjunto de los sépalos.
Los pétalos son, en los casos típicos, hojas de colores llamativos que atraen visualmente a los agentes polinizadores. El conjunto de los pétalos constituye la corola.
Los estambres son hojas muy modificadas portadoras de órganos masculinos, los sacos polínicos (microsporangios), que residen en las anteras, cada una de las cuales se apoyan en un filamento. Los estambres pueden ser muy numerosos, aunque lo más frecuente es que sean una o dos veces el número de pétalos. En la base de los estambres pueden aparecer glándulas productoras de néctar (nectarios), que en otros casos son parte de los pétalos. El conjunto de los estambres se llama androceo.
Por último las hojas más superiores y más pegadas al eje son los carpelos. Éstas son portadoras de órganos femeninos, llamados rudimentos seminales u óvulos, de los que derivarán, tras la fertilización, las semillas. Los carpelos pueden formar uno o más órganos llamados ovarios. El fruto se forma principalmente por la transformación del ovario u ovarios, pero a veces están implicadas otras partes, sobre todo cuando el ovario se desarrolla hundido dentro del tallo de la flor, en la parte llamada tálamo, donde se insertan las diversas piezas florales (ovario ínfero). El conjunto de los carpelos se llama gineceo.
Phylogenetically, the flower is a modified branch. The flower is considered typical of angiosperms, and is composed of four whorls ( "floors") of modified leaves (antofilos). Crossing the axis of the flower from its base toward the end, we find successively:
The sepals are those involving the other sheets in the early stages of development, when the flower is just an asshole. They also avoid entomófilas in the species, the insects from accessing the nectar without going through the stigmas and stamens. The sepals are often welded to form a structure that justifies the name ACOPA calyx (cup) which designates the whole of the sepals.
The petals are, in typical cases, sheets of bright colors that attract pollinators to visually. All the petals as the corolla.
The stamens are highly modified leaves bearing male organs, bags poles (microsporangios), residing in the anthers, each of which rely on a filament. The stamens can be very numerous, but more often they are one or two times the number of petals. At the base of the stamens may be nectar-producing glands (nectaries), which in other cases they are part of the petals. All the stamens are called androecium.
Finally the upper leaves more and more attached to the shaft are the carpels. These carriers are female, called seminal rudiments or ova, which arise after fertilization, the seed. The carpels may form one or more organs called ovaries. The fruit is formed mainly by the transformation of the ovary or ovaries, but sometimes involving other parties, especially when the ovary is sunk into the stem of the flower, known in the thalamus, where they inserted the various floral parts ( infer ovary). The set of carpels is called gynoecium.
Taken on Water Street back in 1986, here's a wharf that's in such bad condition it has sprouted a crop of grass and weeds in a number of areas, probably benefiting from steady fertilization provided by the heavy population of gulls. There are about a half dozen pigeons in residence, but it's clear that the gulls "own" this roost. The wharf and buildings are gone now, and have been for many years. I could have walked out to the wharf but it didn't look safe. The area around the building was undoubtedly spongy and rotten so I figured any photos would best be taken from the shore. I've been visiting Nova Scotia since 1976 and can't recall seeing this structure in any better condition than shown here. I have no idea when it disappeared, but it might have been removed by the town in a "revitalizing" of the waterfront area.
The original color negative image was taken with a Pentax 6x7, 300mm f/4 Takumar lens, using Kodacolor CP-100 roll film.
The original negative was copied using a Nikon D3500 camera, 55mm f/3.5 Micro-Nikkor, fitted with a Nikon 4T close-up lens, a 1.6x Sigma achromatic close-up lens on the 4T. Exposure was 1 second at f/11, ISO set at 100. The light source was a 13.5 watt LED bulb (5000K).
