Alsodes Kaweshkari
''Alsodes kaweshkari'' is a species of frog in the family Alsodidae. This rare species is endemic to southern Chile where it is known from two specimens, the holotype that was collected from Puerto Edén (Wellington Island), and one paratype from Seno Huemules on the mainland. Etymology The specific name ''kaweshkari'' refers to Kaweshkar Indians, "brave people" and hunters of sea lions who live in Puerto Edén. Description Both type specimens are males. They measure in snout–vent length (i.e., large in comparison to most other ''Alsodes''). The body is robust. The flanks and dorsal surfaces are granular, as is the skin around vent and posterior thighs. The ventral skin is smooth with minute granules. The dorsum, arms, and legs are brown; the areas around nostrils, lips and, eyes are light brown. The iris has a coppery reticulum. Belly is whitish yellow. The tympanum is absent. The toes are fringed and have some webbing at their bases. The fingers are unwebbed. However, ... [...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] |
Austral University Of Chile
Austral University of Chile ( es, Universidad Austral de Chile or UACh) is a Chilean research university based primarily in Valdivia, with a satellite campus in Puerto Montt. Founded on September 7, 1954, it is one of the eight original Chilean Traditional Universities. It operates as a nonprofit self-owned corporation under private law, and receives significant state-funding. History Foundation and early years (1942-1968) In 1942, the ''Sociedad de Amigos del Arte (Society of friends of art)'' was formed in the city of Valdivia. Aside from promoting culture, one of the society's main goals was to establish a university in the city. The idea of creating a university was presented to the national congress in the 1950s by the senator for Valdivia, Carlos Acharán Pérez de Arce, who later succeeded in consolidating the project. In a meeting held on 16 February 1954 supporters of installing a university created a directory and proclaimed Eduardo Morales Miranda as president o ...

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 ...

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.

Bernardo O'Higgins National Park
Bernardo O'Higgins National Park () is the largest of the protected areas in Chile, covering an area of in both the Aysén and Magallanes and Antártica Chilena regions. Management of this and other national parks in Chile is entrusted to the ''Corporación Nacional Forestal'' (CONAF). The park is named after General Bernardo O'Higgins, the first head of state of the Republic of Chile. Los Glaciares National Park (Argentina) and Torres del Paine National Park are its neighbours to the east, Laguna San Rafael National Park is located to the north, the Alacalufes National Reserve to the southwest and the Katalalixar National Reserve to the northwest. History The earliest occupants of the area were the Alacaluf people. In 1830, the then-Captain Phillip Parker King on board HMS ''Beagle'' visited the Eyre Fjord. In June 2007, it was announced that between March and May 2007 all the water within a glacial lake located within the park had disappeared, leaving behind a 100-foot- ...

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 ...

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...
