An ecoregion is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation . Ecoregions are also known as "ecozones", although that term may also refer to biogeographic realms.
Washington, D.C., formally the District of Columbia and commonly called Washington or D.C., is the capital city and federal district of the United States. The city is on the Potomac River, across from Virginia, and shares land borders with Maryland to its north and east. Washington, D.C., was named for George Washington, a Founding Father and first president of the United States. The district is named for Columbia, the female personification of the nation.
Smilax is a genus of about 300–350 species, found in the tropics and subtropics worldwide. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and subtropical regions of the world. Common names include catbriers, greenbriers, prickly-ivys and smilaxes. Sarsaparilla is a name used specifically for the Neotropical S. ornata as well as a catch-all term in particular for American species. Occasionally, the non-woody species such as the smooth herbaceous greenbrier are separated as genus Nemexia; they are commonly known by the rather ambiguous name carrion flowers.
Hibiscus is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and those species are commonly known simply as "hibiscus", or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus.
The DC Universe (DCU) is the shared universe in which most stories in American comic book titles published by DC Comics take place. In context, the term "DC Universe" usually refers to the main DC continuity. It contains such well-known superheroes as Batman, Superman, Wonder Woman, the Flash, Green Lantern, Aquaman, Green Arrow, Shazam, Martian Manhunter, and Cyborg; as well as teams such as the Justice League, the Justice Society of America, the Suicide Squad, Doom Patrol, and the Teen Titans. It also contains well-known supervillains, including the Joker, Lex Luthor, the Cheetah, the Reverse-Flash, Sinestro, Black Manta, Deathstroke, Black Adam, Brainiac, and Darkseid.
The Verbenaceae, the verbena family or vervain family, is a family of mainly tropical flowering plants. It contains trees, shrubs, and herbs notable for heads, spikes, or clusters of small flowers, many of which have an aromatic smell.
Campanula is the type genus of the Campanulaceae family of flowering plants. Campanula are commonly known as bellflowers and take both their common and scientific names from the bell-shaped flowers—campanula is Latin for "little bell".
Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas while cultivated around the world. The generic name is also used as the common name.
The United States Botanic Garden (USBG) is a botanical garden on the grounds of the United States Capitol in Washington, D.C., near the James A. Garfield Monument.
Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees.
Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest of eastern Brazil. Other centers of diversity include New Caledonia and Madagascar. Many of the species that occur in the Old World have received a new classification into the genus Syzygium.
Cedrela is a genus of several species in the mahogany family, Meliaceae. They are evergreen or dry-season deciduous trees with pinnate leaves, native to the tropical and subtropical New World, from southern Mexico south to northern Argentina.
The Sapotaceae are a family of flowering plants belonging to the order Ericales. The family includes about 800 species of evergreen trees and shrubs in around 65 genera. Their distribution is pantropical.
Myrica is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales. The genus has a wide distribution, including Africa, Asia, Europe, North America and South America, and missing only from Australia. Some botanists split the genus into two genera on the basis of the catkin and fruit structure, restricting Myrica to a few species, and treating the others in Morella.
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae.
Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.
Desmodium is a genus of plants in the legume family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time. Species are distributed widely – from Quebec to northern Argentina in the Americas, across northern and southern tropical Africa, in the southern Arabian Peninsula, in Myanmar and Thailand, New Guinea, and northern and eastern Australia.
Misodendrum is a genus of hemiparasites which grow as mistletoes on various species of Nothofagus. Its species are all restricted to South America. The name of the genus is incorrectly spelt in a number of ways, including Misodendron and Myzodendron.
Amidorphin is an endogenous, C-terminally amidated, opioid peptide generated as a cleavage product of proenkephalin A in some mammalian species; in humans and most other species, the peptide is 1 residue longer and is not amidated. Amidorphin is widely distributed in the mammalian brain, with particularly high concentrations found in the striatum, and outside of the brain in adrenal medulla and posterior pituitary. The 26-residue peptide named amidorphin is found in several species including bovine, sheep, and pig. Humans and commonly studied lab animals produce a 27-residue peptide that does not have an amidated C-terminal residue; this is due to the absence of a Gly in the precursor sequence and replacement with Ala, which is not a substrate for the amidating enzyme. The properties of the 27-residue peptide are presumably similar to those of amidorphin, although this has not been adequately tested.
