Telmatobufo Ignotus
''Telmatobufo'' is a genus of frogs (false toads) 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. Species The four species are: * ''Telmatobufo australis'' Formas, 1972 * ''Telmatobufo bullocki'' Schmidt, 1952 * ''Telmatobufo ignotus'' Cuevas, 2010 * ''Telmatobufo venustus ''Telmatobufo venustus'' is a species of frog in the family Calyptocephalellidae.

Telmatobufo Bullocki
''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 Nahuelbuta National Park () is one of the few parks located in La Araucanía Region of Chile's Coastal Mountain Range. It sits atop the highest part of the Cordillera de Nahuelbuta. Created in 1939, it consists of 6,832 hectares situated just 16 ....

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of South America
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Telmatobufo Venustus
''Telmatobufo venustus'' is a species of frog in the family Calyptocephalellidae. It is endemic to Chile and occurs on the western slopes of the Andes in Maule and Bío Bío Regions. Its natural habitats are streams in temperate ''Nothofagus'' forests where it is found under rocks along the streams. The only stable population is in the Altos de Lircay National Reserve in Maule. The only other localities, both in the Bío Bío Region, are its type locality in Chillan, where it was not found in 2014, and Ralco where it was last observed in 1981. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... caused by fires, conversion of native habitat to pine and eucalyptus plantations, and in Ralco, hydropower dams.

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyptocephalellidae
The Calyptocephalellidae are a family of toads (although not true members of the Bufonidae) found in Chile containing two living genera, ''Calyptocephalella'' and ''Telmatobufo.'' The genus ''Calyptocephalella'' contains one living species, the helmeted water toad (''C. gayi''), which is very large and mostly aquatic. The genus ''Telmatobufo'' contains four species, '' T. australis'', '' T. bullocki'', '' T. ignotus'', and '' T. venustus''. All five living species within the family are considered threatened, with ''T. bullocki'' and ''T. venustus'' being classified as critically endangered. The family has been present in southern South America since the end of the Cretaceous and were present in the Antarctic Peninsula during the Eocene. While originally widespread in Patagonia east of the Andes, they later became extinct in this region after the Late Miocene, likely due to increasingly cold and arid conditions. A particularly large indeterminate fossil species is known from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptodactylidae
The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes. They are a diverse Family (biology), family of frogs that most likely diverged from other hyloidea, hyloids during the Cretaceous. The family has undergone major taxonomic revisions in recent years, including the reclassification of the former subfamily Eleutherodactylinae into its own family the Eleutherodactylidae; the Leptodactylidae now number 206 species in 15 genera distributed throughout Mexico, the Caribbean, and Central America, Central and South America. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of habitats. Several of the genera within the Leptodactylidae lay their eggs in foam nests. These can be in crevices, on the surface of water, or on forest floors. These foam nests are some of the most varied among frogs. When eggs hatch in nests on the forest floor, the tadpoles remain within the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyptocephalella
''Calyptocephalella'' is a genus of frogs in the family Calyptocephalellidae. It is represented by a single living species, ''Calyptocephalella gayi'', commonly known as the helmeted water toad, Chilean helmeted bull frog or wide-mouth toad. Additionally, there are a few extinct species that only are known from Late Cretaceous and Paleogene fossil remains from Patagonia in South America and in the Antarctic Peninsula (at times when it was warmer and wetter). The helmeted water toad living today is aquatic to semi-aquatic, and found in deep ponds and reservoirs in central Chile and possibly adjacent west-central Argentina.AmphibiaWeb: Calyptocephalella gayi.' Retrieved 21 March 2015. This very large toad typically weighs up to , but sometimes considerably more. It's the world's second largest frog after the goliath frog. It is threatened by capture for human consumption, habitat loss, pollution, introduced species and the disease chytridiomycosis. It is often kept in herpetocultur ...
