Brachygalaxias bullocki (Regan, 1908) | |
Brachygalaxias bullocki (known locally as puye) is a species of ray-finned fish in the family Galaxiidae endemic to Chile. It was listed as Vulnerable since 1994 until changed to Data Deficient in 1996. [1]
The guenons are Old World monkeys of the genus Cercopithecus. Not all members of this genus have the word "guenon" in their common names; also, because of changes in scientific classification, some monkeys in other genera may have common names that include the word "guenon". Nonetheless, the use of the term guenon for monkeys of this genus is widely accepted.
The Galaxiidae are a family of mostly small freshwater fish in the Southern Hemisphere. The majority live in Southern Australia or New Zealand, but some are found in South Africa, southern South America, Lord Howe Island, New Caledonia, and the Falkland Islands. One galaxiid species, the common galaxias, is probably the most widely naturally distributed freshwater fish in the Southern Hemisphere. They are coolwater species, found in temperate latitudes, with only one species known from subtropical habitats. Many specialise in living in cold, high-altitude upland rivers, streams, and lakes.
Telmatobufo is a genus of frogs endemic to southern Chile. Their closest living relative is the monotypic helmeted water toad, Calyptocephalella gayi. These frogs were recently removed from the Leptodactylidae and placed in a new family, the Calyptocephalellidae. All three species of Telmatobufo that have been assessed by the IUCN are considered threatened.
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. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
The Daghestan pine vole is a species of rodent in the family Cricetidae. It is found in Russia, Georgia, Armenia, and Azerbaijan.
Telmatobufo bullocki is a species of frog in the family Calyptocephalellidae. It is endemic to Chile, and is only known from a few locations in the Cordillera de Nahuelbuta, a part of the Chilean Coast Range. It is extremely rare; extensive fieldwork in 1992–2002 turned up only a single adult. It occurs in fast-flowing streams in temperate Nothofagus forest. The tadpoles are free-swimming and feed on algae growing on submerged rocks. It is threatened by siltation of streams caused by clear-cutting. It occurs within the Nahuelbuta National Park.
Brachygalaxias gothei is a species of ray-finned fish in the family Galaxiidae endemic to Chile. It was formerly listed as Vulernable in 1994 until being changed in 1996. It is considered a synonym of Brachygalaxias bullocki but is listed separately by the IUCN Red List.
Mesoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing a single species Mesoperipatus tholloni. It is found in Gabon, making it the only known species of velvet worm in the tropics of Africa, and the only known species of peripatid velvet worm in Africa. Females of this species have 24 to 27 pairs of legs; males have 23 or 24. This species is viviparous, but too little is known of its embryology to describe its reproductive mode in any more detail; the presence of a placenta, for example, has not been confirmed.
Speleoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing the single species Speleoperipatus spelaeus. This species is a pale greenish yellow, almost white, with 22 or 23 pairs of legs and no eyes. Specimens range from 27 mm to 34 mm in length. The minimum number of leg pairs found in this species (22) is also the minimum number found in the neotropical Peripatidae. This velvet worm is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. The majority of the listed species are endemic to North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); one species, S. lucifugus, is extinct.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Hypselodoris rosans is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
The Calyptocephalellidae are a family of toads found in Chile containing two living genera, Calyptocephalella and Telmatobufo.
Hypselodoris iba is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae. It has previously been confused with Hypselodoris bullocki.
Hypselodoris variobranchia is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
