Telmatobufo
''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 The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources.

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 Late 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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 tadpole A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibian. Most tadpoles are fully Aquatic animal, aquatic, though some species of amphibians have tadpoles that are terrestrial animal, ...s 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.

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 or habitat reduction) occurs when a natural habitat is no longer able to support its native species.

Telmatobufo Australis
''Telmatobufo australis'' (commonly known as the Pelado Mountains false toad) is a species of frog in the family Calyptocephalellidae. It is endemic to Chile and occurs in the western and eastern slopes of the Chilean Coast Range in Valdivia and Osorno Provinces. Its natural habitats are fast-flowing streams in temperate ''Nothofagus'' forest. It is a rare species threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species.

Chile
Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Pacific Ocean. Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of , sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández Islands, Juan Fernández, Isla Salas y Gómez, Desventuradas Islands, Desventuradas, and Easter Island, and claims about of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish language, Spanish. Conquest of Chile, Spain conquered and colonized the region in the mid-16th century, replacing Incas in Central Chile, Inca rule; however, they Arauco War ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Helmeted Water Toad
''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-mouthed toad. Additionally, there are a few extinct species that are only known from Late Cretaceous and Paleogene fossil remains from Patagonia in South America and 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 frog typically weighs up to , but sometimes considerably more. It is 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 herpetocult ...

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 of frogs that most likely diverged from other 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 13 genera distributed throughout Mexico, the Caribbean, and 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 nest, without eating, until metamorphosis ... [...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] |
