Alsodes Neuquensis
''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.

Alsodes Verrucosus
''Alsodes verrucosus'' (common name: olive spiny-chest frog) is a species of frog in the family Alsodidae. It is found in the Andes of Chile ( Cautín and Puyehue) and Neuquén and Río Negro Provinces, Argentina. These frogs inhabit temperate ''Nothofagus'' forest where they occur under logs and near damp areas. Tadpoles develop in cold, deep streams. 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 logging.

Alsodes Igneus
''Alsodes igneus'' is a species of frogs in the family Alsodidae endemic to Chile; it is only known from its type locality, Tolhuaca National Park, Malleco Province, on the western slopes of the Andes. The specific name ''igneus'', meaning "something that is of fire", was chosen to symbolize the survival of the population from a great forest fire that affected the type locality in 2000. Description Male ''Alsodes igneus'' measure about in snout–vent length (based on a single male) and females about (based on two females, including the holotype). The snout is short and slightly truncated in dorsal view. There is a black ribbon extending below the canthus rostralis; the background colour is khaki. The dorsal surface is granular. Toes are scarcely fringed and webbing is absent. Tadpoles are up to in length. Habitat The habitat of ''A. igneus'' is '' Nothofagus'' woodland; adults have been found at the edge of a small stream and the tadpole A tadpole is the larval stag ...

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 ...

Alsodes Vanzolinii
''Alsodes vanzolinii'' is a species of frog in the family Alsodidae. Geographic range ''A. vanzolinii'' is endemic to the western slopes of the Nahuelbuta Range, Arauco Province, Chile. Habitat The natural habitats of ''A. vanzolinii'' are temperate forests and rivers. Conservation status ''A. vanzolinii'' is threatened by habitat loss. Alsodes vanzolinii is one of the 18 Alsodes species, 16 of which are present in Chile. Currently, they are considered a critically endangered species by the IUCN (2010) and one of the most threatened Chilean anuran species due to the habitat destruction and expanding exotic tree plantations. It is necessary to increase survey efforts of new populations and how plantation managements, like herbicides and fertilisers are affecting them. Etymology The specific name ''vanzolinii'' honors Paulo Vanzolini, a Brazilian herpetologist Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch o ...
