Passiflora Lutea
''Passiflora lutea'', commonly known as yellow passionflower, is a flowering perennial vine in the family Passifloraceae, native to the central and eastern United States. The vine has three-lobed leaves and small, yellowish-green, fringed flowers that appear in the summer, followed by green fruit that turn almost black at maturity. It grows in moist to wet habitats. Description ''P. lutea'' is a perennial, herbaceous, climbing or trailing, unbranched vine that can reach in length. Curled, springlike tendrils emerging from leaf axils help the vine to climb on structures or other vegetation. The leaves are trilobed, long and broad, with a petiole. Leaves have smooth (entire) margins and are alternate on the stem. The upper surface of the leaves is dark green, and may be mottled with splotches of lighter green. In the north of its range, it is deciduous. The showy flowers appear singly or in pairs on slender flower stalks up to long. Each flower is wide with narrow yellowish ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania
Pennsylvania (; ( Pennsylvania Dutch: )), officially the Commonwealth of Pennsylvania, is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. It borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio to its west, Lake Erie and the Canadian province of Ontario to its northwest, New York to its north, and the Delaware River and New Jersey to its east. Pennsylvania is the fifth-most populous state in the nation with over 13 million residents as of 2020. It is the 33rd-largest state by area and ranks ninth among all states in population density. The southeastern Delaware Valley metropolitan area comprises and surrounds Philadelphia, the state's largest and nation's sixth most populous city. Another 2.37 million reside in Greater Pittsburgh in the southwest, centered around Pittsburgh, the state's second-largest and Western Pennsylvania's largest city. The state's su ...

Oligolecty
The term oligolecty is used in pollination ecology to refer to bees that exhibit a narrow, specialized preference for pollen sources, typically to a single family or genus of flowering plants. The preference may occasionally extend broadly to multiple genera within a single plant family, or be as narrow as a single plant species. When the choice is very narrow, the term ''monolecty'' is sometimes used, originally meaning a single plant species but recently broadened to include examples where the host plants are related members of a single genus. The opposite term is ''polylectic'' and refers to species that collect pollen from a wide range of species. The most familiar example of a polylectic species is the domestic honey bee. Oligolectic pollinators are often called oligoleges or simply specialist pollinators, and this behavior is especially common in the bee families Andrenidae and Halictidae, though there are thousands of species in hundreds of genera, in essentially all known b ...

Anthemurgus Passiflorae
''Anthemurgus passiflorae'' (the passionflower bee) is a small (7.5-8.5 mm long), black, bee that occurs from central Texas to North Carolina and north to Illinois. Females of this solitary bee use collected nectar and pollen to feed larvae located in nests constructed in the ground (through mass provisioning). This uncommon bee is unusual for two reasons: first, the only known pollen host is a single species—the yellow passionflower (''Passiflora lutea'') (such specialization is called oligolecty); second, because of its size and foraging habits, the passionflower bee is thought to contribute little or nothing toward the pollination of its host plant. Female bees remove pollen from ''P. lutea'' by suspending themselves under an anther and scraping the pollen out with open mandibles. This unique position of pollen collection almost never results in pollination as the female bee rarely touches the stigma. The genus ''Anthemurgus'' contains only the passionflower bee and th ...

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zebra Longwing
''Heliconius charithonia'', the zebra longwing or zebra heliconian, is a species of butterfly belonging to the subfamily Heliconiinae of the family Nymphalidae. It was first described by Carl Linnaeus in his 1767 12th edition of ''Systema Naturae''. The boldly striped black and white wing pattern is aposematic, warning off predators. The species is distributed across South and Central America and as far north as southern Texas and peninsular Florida; there are migrations north into other American states in the warmer months. Zebra longwing adults roost communally at night in groups of up to 60 adults for safety from predators. The adult butterflies are unusual in feeding on pollen as well as on nectar; the pollen enables them to synthesize cyanogenic glycosides that make their bodies toxic to potential predators. Caterpillars feed on various species of passionflower, evading the plants' defensive trichomes by biting them off or laying silk mats over them. Mass spraying of naled ...

Dryas Julia
''Dryas iulia'' (often incorrectly spelled ''julia''),Lamas, G. (editor) (2004). Atlas of Neotropical Lepidoptera. Checklist: Part 4A. Hesperioidea – Papilionoidea. commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed (or nymphalid) butterfly. The sole representative of its genus ''Dryas'', it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described. Its wingspan ranges from 82 to 92 mm, and it is colored orange (brighter in male specimens) with black markings; this species is somewhat unpalatable to birds and belongs to the "orange" Mullerian mimicry complex. This butterfly is a fast flier and frequents clearings, paths, and margins of forests and woodlands. It feeds on the nectar of flowers, such as lantanas (''Lantana'') and shepherd's-needle (''Scandix pecten-veneris''), and the tears of caiman, the eye of ...

Gulf Fritillary
The Gulf fritillary or passion butterfly (''Dione vanillae'') is a bright orange butterfly in the subfamily Heliconiinae of the family Nymphalidae. That subfamily was formerly set apart as a separate family, the Heliconiidae. The Heliconiinae are "longwing butterflies", which have long, narrow wings compared to other butterflies. ''Dione vanillae'' is most commonly found in the southern areas of the United States, specifically in many regions of Florida and Texas. Gulf fritillaries have a chemical defense mechanism in which they release odorous chemicals in response to predator sightings. As a result, common predators learn to avoid this species. Pheromones play a critical role in male-female courtship behaviors, with male gulf fritillaries emitting sex pheromones that contribute to mate choice in females. The scientific name ''Papilio vanillae'' was given to the gulf fritillary by Carl Linnaeus in 1758, based on a 1705 painting by Maria Sibylla Merian (''The Metamorphosis of ...

Butterfly Garden
Butterfly gardening is a way to create, improve, and maintain habitat for lepidopterans including butterflies, skippers, and moths. Butterflies have four distinct life stages—egg, larva, chrysalis, and adult. In order to support and sustain butterfly populations, an ideal butterfly garden contains habitat for each life stage. Butterfly larvae, with some exceptions such as the carnivorous harvester (''Feniseca tarquinius''), consume plant matter and can be generalists or specialists. While butterflies like the painted lady (''Vanessa cardui'') are known to consume over 200 plants as caterpillars, other species like the monarch (''Danaus plexippus''), and the regal fritillary (''Speyeria idalia'') only consume plants in one genus, milkweed and violets, respectively. As adults, butterflies feed mainly on nectar, but they have also evolved to consume rotting fruit, tree sap, and even carrion. Supporting nectarivorous adult butterflies involves planting nectar plants of dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvial
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passiflora Incarnata
''Passiflora incarnata'', commonly known as maypop, purple passionflower, true passionflower, wild apricot, and wild passion vine, is a fast-growing perennial vine with climbing or trailing stems. A member of the passionflower genus ''Passiflora'', the maypop has large, intricate flowers with prominent styles and stamens. One of the hardiest species of passionflower, it is both found as a wildflower in the southern United States and in cultivation for its fruit and striking bluish purple blooms. ''Passiflora incarnata'' fruit contain many seeds, each surrounded by an aril holding edible juice, and this juice can be consumed fresh or used to flavor processed products. Description The stems can be smooth or pubescent; they are long and trailing, possessing many tendrils. Leaves are alternate and palmately 3-lobed and occasionally 5-lobed, measuring . They have two characteristic glands at the base of the blade on the petiole. Flowers have five bluish-white petals. They exhibit a ...
