Batrachyla Nibaldoi
''Batrachyla nibaldoi'' is a species of frog in the family Batrachylidae. It is endemic to Chile and known from the Los Lagos and Aysén Regions between Villa O'Higgins in the south and Kent and Melchor Islands in the north; there is a record from Alao Island further north but this might represent ''Batrachyla taeniata''. The specific name ''nibaldoi'' honors , Chilean marine biologist, in recognition of his "remarkable contribution to the development of the zoology in Chile". Common name Nibaldo's wood frog has been coined for it. Description Adult females measure in snout–vent length; male length is not reported. The snout is rounded in dorsal view and sloping in lateral profile. The tympanum is visible; the supra-tympanic fold is evident. The fingers and toes are slender and have moderately pointed tips. The fingers have no webbing whereas the toes have thin, basal webbing. Dorsal ground color is from light brown or yellowish brown to grayish, with dark brown spots that f ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothofagus Antarctica
''Nothofagus antarctica'' (''Antarctic beech''; in Spanish ''Ñire'' or ''Ñirre'') is a deciduous tree or shrub native to southern Chile and Argentina from about 36°S to Tierra del Fuego (56° S), where it grows mainly in the diminishing temperate rainforest. Its occurrence on Hoste Island has previously earned it the distinction of being the southernmost tree on earth; however, in 2019 it was established that '' N. betuloides'' was found further south, on Hornos Island. ''N. antarctica'' is present on Hornos as well, but the southernmost individual is slightly further north (17 m) of the southernmost ''N. betuloides''. Description ''Nothofagus antarctica'' typically grows 5–25 m (12–80 ft) tall and has a slender trunk with scaly bark. The leaves are simple and alternate, growing 2–4.5 cm long, and often viscid, with a sweetly scented wax. The leaf color is medium green, turning yellow to orange in the fall. The leaves are broadly ovate to triangular, crinkly, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Chile
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Chile
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 ...

Batrachyla
''Batrachyla'' is a genus of frogs in the family Batrachylidae. Sometimes known as the South American wood frogs, these frogs are distributed in southern South America (Argentina and Chile Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east a ...). Species There are five species in the genus: * '' Batrachyla antartandica'' Barrio, 1967 * '' Batrachyla fitzroya'' Basso, 1994 * '' Batrachyla leptopus'' Bell, 1843 * '' Batrachyla nibaldoi'' Formas, 1997 * '' Batrachyla taeniata'' (Girard, 1855) References Batrachylidae Amphibians of South America {{hyloidea-stub ...

American Mink
The American mink (''Neogale vison'') is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe, Asia and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus ''Neovison'' following the extinction of the sea mink (''N. macrodon''), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus ''Neogale'', which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laguna San Rafael National Park
Laguna San Rafael National Park () is a park located on the Pacific coast of southern Chile. The park is named for the San Rafael Lagoon formed by the retreat of the San Rafael Glacier. Created in 1959, it covers an area of and includes the Northern Patagonian Ice Field. A fjord more than long is one of the park's principal attractions. History Non-indigenous people first explored the area of Laguna San Rafael in the year 1675. The glacier of the same name was a land-terminating glacier during that time. It probably reached again the lagoon at some time between 1741 and 1766, and it has been a tidewater glacier since that date. The park was designated a World Biosphere Reserve by UNESCO in 1979.UNESCO - Park description at UNESCO World Biosphere Reserve Geography The park comprises some of ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carretera Austral
The Carretera Austral (CH-7, ''in English: Southern Way'') is the name given to Chile's Route 7. The highway runs south for about from Puerto Montt to Villa O'Higgins, passing through rural Patagonia. Carretera Austral provides road access to Chile's Aysén Region and southern parts of Los Lagos Region. These areas are sparsely populated and despite its length, Carretera Austral provides access to only about 100,000 people. The largest city along the entire road is Coyhaique with a population of 44,850 in 2002. History Construction of the highway was commenced in 1976 under the dictatorship of Augusto Pinochet in order to connect a number of remote communities. Before that, in the 1950s and 1970s, there had been unsuccessful attempts to build access roads in the region. It is among the most ambitious infrastructure projects developed in Chile during the 20th century. As it was constructed during the military dictatorship, the Carretera Austral bears the unofficial name of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothofagus Betuloides
''Nothofagus betuloides'', Magellan's beech or ''guindo'', is a tree native to southern Patagonia. In 1769, Sir Joseph Banks collected a specimen of the tree in Tierra del Fuego during Captain Cook's first voyage. Its occurrence on Hornos Island earns it the distinction of being the southernmost tree on Earth. Distribution ''Nothofagus betuloides'' grows from southern Chile and southern Argentina (40°S) to Tierra del Fuego (56°S). It is found from sea level to above mean sea level. One specimen growing near the southeastern corner of Hornos Island (Cape Horn) was identified in 2019 as the southernmost tree in the world. Description It is an evergreen tree up to tall, with a columnar appearance. In its natural environment, it tolerates cold winters and absence of heat in summer. Specimens from the southern forests resist temperatures down to . Cultivation It succeeds in Scotland. Trees planted in the Faroe Islands, which were imported directly from its southernmost distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without trees apart from those near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the temperate grasslands, savannas and shrublands biome A steppe may be semi-arid or covered with grass or with shrubs or with both, depending on the season and latitude. The term " steppe climate" denotes the climate encountered in regions too dry to support a forest but not dry enough to be a desert. Steppe soils are typically of the chernozem type. Steppes are usually characterized by a semi-arid or continental climate. Extremes can be recorded in the summer of up to and in winter, . Besides this major seasonal difference, fluctuations between day and night are also very great. In both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night. Mid-latitude steppes feature hot summers and cold wint ...
