Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle.IUCN. (2003). Guidelines for Application of IUCN Red List Criteria at Regional Levels: Version 3.0'' IUCN Species Survival Commission. IUCN, Gland, Switzerland and Cambridge, UK. ii + 26 pp. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction. Not all EW species are rare. An example is the ''Brugmansia'' genus, where all seven species are widely cultivated, but none are found in the wild. Ultimately, the purpose of preserving biodiversity is to maintain ecological function to prevent ecological extinction. Examples Examples of specie ...

Corvus Hawaiiensis FWS
''Corvus'' is a widely distributed genus of passerine birds ranging from medium-sized to large-sized in the family Corvidae. It includes species commonly known as crows, ravens, and rooks. The species commonly encountered in Europe are the carrion crow, hooded crow, common raven, and rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "raven". The 46 or so members of this genus occur on all temperate continents except South America, and several islands. The ''Corvus'' genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective name for a group of crows is a "flock" or a "murder". Recent research has found some crow species capable of not only tool use, but also tool construction. Crows are now considered to be among the world's most intelligent animals with an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Escarpment Cycad
''Encephalartos brevifoliolatus'', the escarpment cycad, is a cycad in the African genus ''Encephalartos''. It is extinct in the wild.

Partula (gastropod)
''Partula'' is a genus of air-breathing tropical land snails, terrestrial pulmonate gastropod mollusks in the family Partulidae.Myers, P.; Espinosa, R.; Parr, C. S.; Jones, T.; Hammond, G. S. & Dewey, T. A. (2006). The Animal Diversity Web (online). Accessed at http://animaldiversity.org. Many species of ''Partula'' are known under the general common names " Polynesian tree snail" and " Moorean viviparous tree snail". Partulids are distributed across of Pacific Ocean islands, from the Society Islands to New Guinea. Once used as decorative items in Polynesian ceremonial wear and jewelry, these small snails (averaging about one-half to three-quarters of an inch in length) gained the attention of science when Dr. Henry Crampton (along with Yoshio Kondo) spent 50 years studying and cataloging partulids, detailing their remarkable array of morphological elements, ecological niches, and behavioral aspects that illustrate adaptive radiation.

Père David's Deer
The Père David's deer (''Elaphurus davidianus''), also known as the ''milu'' () or elaphure, is a species of deer native to the subtropical river valleys of China. It grazes mainly on grass and aquatic plants. It is the only extant member of the genus '' Elaphurus''. Some experts suggest demoting ''Elaphurus'' to a subgenus of ''Cervus''. Based on genetic comparisons, Père David's deer is closely related to Eld's deer. Père David's deer were hunted almost to extinction in their native China by the late 19th century, but a number were taken to zoos in France and Germany and the deer was bred successfully in captivity. In the early 20th century, the British nobleman and politician Herbrand Russell, 11th Duke of Bedford, acquired a few Père David's deer from the Berlin Zoo and built up a large herd on his estate at Woburn Abbey. In the 1980s, the duke's great-grandson Robin Russell, 14th Duke of Bedford, donated several dozen deer to the Chinese government for reintroducin ...

Panamanian Golden Frog
The Panamanian golden frog (''Atelopus zeteki''), also known as Cerro Campana stubfoot toad and other names, is a species of toad endemic to Panama. Panamanian golden frogs inhabit the streams along the mountainous slopes of the Cordilleran cloud forests of west-central Panama. While the IUCN lists it as Critically Endangered, it may in fact have been extinct in the wild since 2007. Individuals have been collected for breeding in captivity in a bid to preserve the species. The alternative common name, Zetek's golden frog, and the epithet ''zeteki'' both commemorate the entomologist James Zetek. Description Despite its common name, the Panamanian golden frog is a true toad, a member of the family Bufonidae. It was first described as a subspecies of '' Atelopus varius'', but is now classified as a separate species. The Panamanian golden frog is a national symbol and is considered to be one of the most beautiful frogs in Panama. The skin colour ranges from light yellow-green to ...

Cachorrito De Charco Palmal
''Cyprinodon longidorsalis'', the cachorrito de charco palmal or La Palma pupfish, is a species of fish in the family Cyprinodontidae. It was endemic to the Ojo de Agua la Presa in southwestern Nuevo Leon state in Mexico, but became extinct in the wild in 1994 due to habitat loss (now survives only in captivity). The same freshwater spring system was the home of three other pupfish: '' Cyprinodon ceciliae'' (extinct), '' Cyprinodon inmemoriam'' (extinct) and '' Cyprinodon veronicae'' (extinct in the wild, survives in captivity). Although these were from the same spring system, each was restricted to its own individual spring pool. The Charco La Palma pool and its spring had a combined area of about and was no more than at the deepest point, making the range of the La Palma pupfish perhaps the smallest known for any vertebrate species. This tiny spring pond also was the home of a now-extinct, undescribed species of '' Cambarellus'' crayfish. The La Palma pupfish is a ray-finned f ...

Hawaiian Crow
The Hawaiian crow or alalā (''Corvus hawaiiensis'') is a species of bird in the crow family, Corvidae, that is currently extinct in the wild, though reintroduction programs are underway. It is about the size of the carrion crow at in length, but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage and long, bristly throat feathers; the feet, legs, and bill are black. Today, the Hawaiian crow is considered the most endangered of the family Corvidae. They are recorded to have lived up to 18 years in the wild, and 28 years in captivity. Some Native Hawaiians consider the Hawaiian crow an '' aumakua'' ( family god).Banko, P. C., D. L. Ball, and W. E. Banko (2020). Hawaiian Crow (Corvus hawaiiensis), version 1.0. In Birds of the World (A. F. Poole and F. B. Gill, Editors).
