Alsodes Hugoi
''Alsodes hugoi'' is a species of frogs in the family Alsodidae. It is endemic to Chile and only known from its type locality, Río Lircay, in Alto de Vilches, Talca Province, on the western slopes of the Andes. The specific name ''hugoi'' honors Professor Hugo Campos Cereceda, for his "remarkable contributions to the development of the natural sciences in Chile". Description The type series consists of two adult males and two adult females. The males measure and females in snout–vent length. A juvenile specimen measured SVL. tympanum is absent. The body is robust with well-developed arms and legs. The fingers have rounded tips and no webbing. The toes are long, thick, and with rounded tips. There is no webbing but some membrane between the toes IV and V. The dorsal coloration is light brown with golden tints. The legs and arms have black bars on their dorsal surfaces. There is a black triangular mark between the eyes and pointing backward. The venter is whitish. Late-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clonal rep ...

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 ...

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] |
Alsodes
''Alsodes'' is a genus of alsodid frogs found in Chile and Argentina. It is the most species-rich frog genus in Patagonia. Common name spiny-chest frogs has been coined for them.Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 70 Description Characteristic for this genus is that during the reproductive season, adult males have thorny structures on the fingers and rounded spiny patches on the chest. Breeding takes place in high-elevation streams, and tadpole A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found i ...s have slow development, including overwintering under ice cover.

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 reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

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.

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alsodidae
The Alsodidae are a small family of frogs from South America between Patagonia and southern Brazil. It contains 30 species in three genera. This family, along with several other families, used to be included in the family Leptodactylidae. It was then a subfamily in the family Cycloramphidae, before being recognized as a family first in 2011. Genera The family contains three genera: *'' Alsodes'' Bell, 1843 (19 species) *'' Eupsophus'' Fitzinger, 1843 (10 species) *'' Limnomedusa'' Fitzinger, 1843 (1 species) However, the placement of ''Limnomedusa'' is highly uncertain, and it might belong to the family Cycloramphidae. In contrast, '' Alsodes''+'' Eupsophus'' group (''sensu stricto'', after moving some species formerly included in the latter genus to other genera) forms a well-supported, monophyletic group. These genera are Patagonian endemics and represent the largest part of the amphibian diversity in that area. ''Eupsophus'' species are restricted to forested areas at southern ...
