Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids.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. Unlike most other orchids, slipper orchids have two fertile anthers — they are 'diandrous'. 23979

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 life cycle of white tail dear..Fawns are born in may, and in October new ones begin life as a fertilized egg. Bucks like this one show up in my back yard only in fall.
Horseshoe Crabs come to the shallows for mating. Females are larger than males, so in this picture the lucky female has three males in pursuit. Some females were observed with up to five beaus. She will lay up to 60,000 to 120,000 eggs, which are like "caviar" to shorebirds.
Though they are called "crabs", (which are crustaceans), they are more closely related to arachnids (which includes spiders).
Fossils of Horseshoe Crabs have been found in rock, dated to over 450 000, 000 years ago, leading some people to call Horseshoe Crabs "living fossils".
The male grasps the female by the back of her head during and after mating to prevent other males from mating with her. Her eggs are only fertilized as they are deposited in the water. See flic.kr/p/2j4pm2j

Galapagos Islands - (Isabela Island)
The yellow flowers are arranged in cymes and are sweetly scented. The petals of each flower are fused together to form a trumpet shape, 2–4 cm (0.8–1.6 in) across at the mouth, which has five to eight lobes. Inside the flower there are five to eight stamens. After fertilization, a globular white fruit (a drupe) forms, 8–12 millimetres (0.3–0.5 in) across, containing from one to four seeds. The fruit has a fleshy pulp that is initially slimy when the fruit is opened, but becomes sticky on exposure.

Female (left) and male Brook Trout (Salvelinus fontinalis) cruise in a stream during the annual fall spawning season. The female will dig a redd or nest, deposit her roe, then wait for males to fertilize her eggs, all the while guarding her nest. The stream is so shallow at this point that the colors of the trout are reflected in the surface water. Image taken in Rocky Mountain National Park of Colorado.
This sergeant major, Abudefduf saxatalis, guards his reproductive effort, a patch of thousands of fertilized eggs. He fans the eggs to keep detritus and algae from collecting, and to keep other fish from eating the eggs. These duties last 6 to 7 days, the time for fertilized eggs to hatch.
The hull of this ship attracted many sergeant majors. Most were colored brightly like this one, but about 20% adopted more subdued colors just while tending eggs.

Marvel-of-Peru is a colorful flower that is easy to grow. It blooms in the late afternoon or evening and closes up at night. The plant needs to be watered regularly and fertilized every few weeks. It is a hardy plant that can tolerate a variety of climates.
The spirit of creation
preferred the verdant vegetation
to that dwelling built by man.
God’s caricature
is closer to that of nature.
In Eden did he put his man.
In that garden
all could find pardon
each and every man.
Forget your worried regretful toil.
Leave that shit to fertilize the soil
in the garden blessing some other man.

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.

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 can be up to 26 feet long and they 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.

Apparently armadillos have limited vision but very keen sense of smell. And they have sharp claws which can dig well, but we saw four of them rooting around with their noses, somewhat pig-like. While armadillos are often considered nocturnal, especially in summer, we saw these in mid-day. They had come out from under a raised structure. Since we saw four together, it was interesting to learn that a single fertilized egg gives rise to four separate embryos, such that each litter consists of four identical quadruplets.
We did not expect to see armadillos, even after we had seen several dead ones along roads. Apparently their range has gradually expanded north and northeast and we were near the current edge of that expansion. (This expansion has been going on for many years, at least since 1840 when they were first noted north of the Rio Grande along Texas and Mexico.)
Every year thousands of these beautiful iconic symbols of our northern nation go out to parts of Europe and the USA where they grace (and fertilize) the local parklands and golf courses.

Bald eagles along the Nanek River enjoy the salmon run. They pluck them from the water and pick up the bits the bears do not finish. They carry the fish to the tree tops to eat. Fish remains in the trees rinse down to the tree roots, fertilizing the trees. Healthy trees prevent erosion and keep silt from clouding the rivers when it rains or the snow melts. Salmon need clear water to spawn in. Salmon, bear, eagle, tree - all connected, all important.
Insects are vital pollinators, playing a crucial role in the reproduction of many plants, including those that produce our food. Key insect pollinators include bees (like honeybees and bumblebees), flies, wasps, beetles, butterflies, and moths. These insects transfer pollen between flowers, enabling fertilization and the production of seeds, fruits, and vegetables..
This is the same yellow Holiday cactus in normal daylight. The flowers are packed in very tight with many buds. It must have been heavily fertilized.

A Pink Salmon, desperately trying to elude a hungry Black Bear, leaps from the shallow spawning steam only to land on a rock. For all their bulk, bears are agile and quick, and this one is about to clamp down on her meal... but... believe it or not, the salmon did a backflip and escaped! (Unfortunately it flipped behind that out of focus rock in the left foreground, so my next frame wasn't as good.)
My title refers to both of them. The salmon needs to spawn. The bear needs to pack on calories to get through the coming winter. The salmon that don't make it feed not only bears, but eagles, crows, wolves, vultures, gulls, and the forest itself (bears and eagles will carry their catch into the woods to consume, and the leftovers will fertilize the forest floor). This is how a healthy ecosystem should work. Whether the BC coastal ecosystem is healthy enough to maintain itself at this point is anyone's guess...

This female Lesser Meadow Katydid (Conocephalus spp.) was not impressed with my watering skills. The fig tree leaf it was using for sun shade was disturbed. Katydids have long antennae which differentiates them from grasshoppers. Females have straight, syringe-like ovipositors that they use to inject fertilized eggs into plant stems. It is not a stinger.
The canopy of leaves cloaking the Giant Forest covers the work of a dramatic change agent - Fire. Fire has shaped every sequoia you see. Young trees grow tall fast to rise above the low flames that typically burn here. Then they put on thick bark, which protects them from most fire. Black scars on the sequoia trunks reveal the trees' ability to survive.
If today's view includes smoke from a park fire, this may be a good day for the sequoia grove. Flames clear forest litter and fertilize the soil, prompt cones to release seeds, and open the forest to sun. This creates the ideal seedbed for sequoias. Other trees and wildlife benefit from the fire's effects, as well.

Butterflies reproduce the way other animals do -- sperm from a male fertilizes eggs from a female. Males and females of the same species recognize one another by the size, color, shape and vein structure of the wings, all of which are species specific. Butterflies also recognize each other through pheromones or scents. During mating, males use clasping organs on their abdomens to grasp females.
Many male butterflies deliver more than just sperm to their mates. Most provide a spermatophore, a package of sperm and nutrients the female needs to produce and lay eggs. Some males collect specific nutrients to produce a better spermatophore in an attempt to attract a mate. Some females, however, don't have a choice -- in some species, males mate with females before they have left their chrysalis or swarm the chrysalis waiting for the female to appear. In most species, males and females look a lot a like, but females often have larger abdomens for carrying their eggs.
Females store the sperm in a sac called a bursa until she's ready to lay her eggs. She fertilizes her eggs as she lays them, using the last sperm she received first. For this reason, males of some species will leave a substance that dries into a film on the female's abdomen in an effort to keep her from mating with other males. Females lay their eggs one at a time or in batches of hundreds depending on their species.
A butterfly has to take special care when laying eggs. The eggs must be kept warm and at the right humidity level. Too much moisture and the egg will rot or be attacked by fungus. Too little and the egg will dry out. Caterpillars also need to start eating as soon as they hatch, so most of the time females place the eggs directly onto a plant the caterpillar will eat. Typically, the eggs attach to the underside of a leaf so they are hidden from predators.
The Peleides Blue Morpho, Common Morpho, or The Emperor (Morpho peleides) is an iridescent tropical butterfly found in Mexico, Central America, northern South America, Paraguay, and Trinidad. Some authorities believe that peleides is a subspecies of Morpho helenor.
The brilliant blue color in the butterfly's wings is caused by the diffraction of the light from millions of tiny scales on its wings. It uses this to frighten away predators, by flashing its wings rapidly. The wingspan of the Blue Morpho butterfly ranges from 7.5–20 cm (3.0–7.9 in). The entire Blue Morpho butterfly lifecycle, from egg to adult is only 115 days. Morpho peleides drinks the juices from rotting fruits for food. Its favorites in captivity are mango, kiwi, and lychee. Morpho peleides butterflies live in the rainforests of South America and can be found in Mexico and Central America. The caterpillar Blue Morpho butterfly is red-brown with patches of bright green.

I've said it before, Damselfly sex is COMPLICATED. The (blue) male deposits sperm from his primary genitals near the tip of his tail on to his secondary genitals on his abdomen then grasps a willing female by the back of her head. When the mood takes her, she bends round and collects the sperm with the tip of her tail. The eggs are not fertilized until they are deposited, usually in water, so the male keeps hold of her to prevent other males from mating with her. They can fly around in tandem, both 'in the wheel' as here, or line astern with no apparent difficulty.
Spring peepers are one of the first frogs to emerge in the spring and one of the first sounds you hear that lets you know warm weather is soon to come.
Their season starts off in the shallow ponds and flooded marshes to lay and fertilize the eggs. The high pitch "PEEP" call can be heard for long distances as males try to attract the attention of a female and at the same time, fend off rival males trying to do the same. As spring progresses and the peepers eggs are laid, other larger frogs enter the water and the peepers seem to retreat to drier areas. Still calling loudly but from the relative safety of a elevated shrub or small tree.
The goliath stick insect is one of the larger species of stick found in their native home of Australia. They are one of an estimated 150 stick insect species found in Australia.
Here they spend most of their life in the treetops where they will feed on eucalypt and acacia leaves.
Females can produce up to 1000 eggs in their lifetime with these eggs not needing to be fertilized by a male. If this does not take place though they will only produce female hatchlings
These 2 were about 2-3 feet away from the water; a shallow wetland in the woods. Numerous others were swimming around and croaking. They stayed this way for as long as I was there; > 10 min. I got pretty close (a few feet) and it did not bother them. I am trying to figure out what this behavior is all about. Fertilizing eggs would happen in the water. So ?????
This bald eagle is one of a mating pair. Its left the nest area to fly over near its mate in a nearby tree. Eggs have not been laid yet, but the nest is ready and they've been very busy making sure that any eggs are fertilized.

It was annual fertilizing time for The Ween Tree, as seen to the left, which was the reason I was out here on this particular morning. While not massive in size or volume, he was looking relatively healthy as compared to how he was looking the past few years. This year he was showing signs of producing some cones. Each year, I'll head out here and put a few fertilizer spikes in the ground and water them in. My hope was that he'd be a good shade tree for my later years that I can sit under and watch the trains, but at the rate he's growing, there's not going to be much shade by the time I'm truly an old man! Regardless, it's a fun annual thing I look forward to. And seeing a pair of ACes, despite how ratty they're looking, was a nice bonus...
Twins are the norm for healthy whitetail does in good habitat. At birth, the does hide them in different locations to improve survival.
Whitetail twins are typically fraternal, not identical, resulting from two eggs released by the doe and fertilized by different sperm. Approximately 20-25% of twin fawns have different fathers due to does mating with multiple bucks during estrus. Identical twins (from a single egg splitting) are possible but rare.
Our beautiful world, pass it on.
A pollinator is an animal that carries pollen from one flower to another, enabling fertilization and seed production. Pollinators include insects like bees, beetles, and butterflies; birds; bats; and even wind and water.
Low sunlight hits the cliffs of Dyrhólaey, a peninsula near the village of Vik in southern Iceland. The backdrop is a rare view of the Mýrdalsjökull ice cap, which receives as much as 10 m (33 feet/400 inches) of precipitation annually. Underneath the ice cap lies Katla, a volcano which erupts on average every 40-80 years; it's last eruption was in 1918. The Icelandic government geohazards group is concerned about the potential buildup of magma, particularly after the eruption of nearby Eyjafjallajökull in 2010. Recent increases in seismic activity may be signaling an eruption soon.
Despite the low light, sunset was still two hours away. The whitish streaks on the cliff is guano (bird poop), which has clearly fertilized the vegetation at the base of the cliff. Numerous seabirds nest in the cliffs in May and June, mainly gulls, but also puffins such as the pair seen in a previous post. (#2)

Picardie is one of the 26 regions of France, and is located in the northern part of France.
Picardy (French: Picardie) is a historic region in northern France that is now within the departments of Aisne, Oise, Pas-de-Calais, and Somme. Amiens was the region's capital.
On Picardy's fertile soils they grow wheat, sugar beets and fodder crops. Dairy and beef cattle are raised, and intensive vegetable cultivation takes place on the heavily fertilized, drained peat in the valley of the Somme River.
