Dendrophryniscus Krausae
''Dendrophryniscus'' is a genus of true toads in the family Bufonidae, sometimes known as tree toads. They are endemic to the Atlantic Forest of Brazil. Taxonomy Until 2012, the genus ''Dendrophryniscus'' included the species now separated to the genus '' Amazophrynella''. This was based on molecular genetic evidence that indicated deep divergence between an Amazonian and an Atlantic Forest clade, the latter retaining the name ''Dendrophryniscus'' whereas the former was described as a new genus ''Amazonella'', later amended to ''Amazophrynella'' because of homonymy. Description The species of ''Dendrophryniscus'' are small to medium-sized toads measuring in snout–vent length. Their body form resembles those of the genus ''Atelopus''. The hind limbs are well developed. The parotoid glands are absent, as are external tympana. The skin is uniformly granulose to warty. Dorsal coloration is cryptic. With the exception of '' Dendrophryniscus leucomystax'', species of the genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Fauna Of Brazil
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dendrophryniscus Stawiarskyi
''Dendrophryniscus stawiarskyi'' is a species of toad in the family Bufonidae. It is endemic to Brazil and only known from its type locality, Bituruna in the Paraná state. Its natural habitat is humid rainforest where it occurs in the forest leaf-litter. 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 ....

Dendrophryniscus Skuki
''Dendrophryniscus skuki'' is a species of toad in the family Bufonidae. It is endemic to northeastern Brazil and only known from its type locality in the municipality of Itacaré, state of Bahia. This species is dedicated to herpetologist Gabriel "Gabo" Skuk, the species describer's friend who perished in a diving accident. Description The holotype is an adult male with a stout build and measuring in snout–vent length. The head is slightly longer than it is wide. The snout is long, narrow, and spatulate when viewed from above. The canthus rostralis is distinct and slightly concave. The eyes are large but not prominent. The tympanum is hidden. Apart from the gular region and chest that are barely rugose, skin is rugose with uniformly distributed rounded tubercles. The parotoid glands are large and rounded. The fingers and the toes are slender and have rounded tips and no webbing, although the toes are slightly fringed. The preserved specimen is dorsally dark brownish g ...

Dendrophryniscus Proboscideus
''Dendrophryniscus proboscideus'' is a species of toad in the family Bufonidae. It is endemic to Southeastern Brazil and known from isolated records in fragments of Atlantic Forest in eastern Bahia and northeastern Minas Gerais states. Taxonomy This species has been through a series of taxonomic changes. It was originally named ''Phryniscus proboscideus'', and then ''Rhamphophryne proboscidea''. A merge of the genus ''Rhamphophryne'' into ''Rhinella'' briefly placed this species into junior homonymy with a different species, ''Rhinella proboscidea''. To resolve this, it was renamed ''Rhinella boulengeri'' in 2007. A 2012 analysis moved the species into the genus ''Dendrophryniscus'' and renamed it ''Dendrophryniscus proboscideus''. Description ''Dendrophryniscus proboscideus'' are relatively large among the ''Dendrophryniscus'', measuring in snout–vent length. The body is slender and warty. The snout is protruding. The males have nuptial pads. Habitat and conservation ''D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
