Charadrahyla Altipotens
The yellowbelly voiceless tree frog (''Charadrahyla altipotens'') is a species of frog in the family Hylidae endemic to Mexico. It inhabits the Pacific slopes of the Sierra Madre del Sur in southern Oaxaca, between 1,300 and 2,000 meters elevation. It is known from two subpopulations, one near San Agustín Loxicha and the other north of the San Gabriel Mixtepec San Gabriel Mixtepec is a town and municipality in Oaxaca in south-western Mexico. It is part of the Juquila District in the center of the Costa Region. The name "Mixtepec" means "Hill of clouds". The municipality covers an area of 482.26 km² of .... Its extent of occurrence (EOO) is 2,240 km2, but may occur more widely than currently recorded. It prefers rocky streams with abundant vegetation in montane pine-oak forests and cloud forests. It is threatened by habitat loss. References Charadrahyla Endemic amphibians of Mexico Fauna of the Sierra Madre del Sur Amphibians described in 1968 Taxonomy arti ...

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] |
Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** ''Boana'' – gladiator treefrogs *** ''Bokermannohyla'' *** ''Hyloscirtus'' *** ''Myersiohyla'' *** ''Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***''Dendropsophus'' *** '' Julianus'' *** ''Lysapsus'' ...

Endemism
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] |

Sierra Madre Del Sur
The Sierra Madre del Sur is a mountain range in southern Mexico, extending from southern Michoacán east through Guerrero, to the Isthmus of Tehuantepec in eastern Oaxaca. Geography The Sierra Madre del Sur joins with the Eje Volcánico Transversal (Trans-Mexican Volcanic Belt) of central Mexico in northern Oaxaca, but is separated from this range further west by the valley of the Balsas River and its tributary the Tepalcatepec River. The mountains' highest point is Cerro Nube – , in southern Oaxaca, and just one major highway crosses the range between Acapulco and Mexico City. Although separated from the main part of the Sierra Madre del Sur by the deep canyon of the lower Río Balsas, the mountains of southern Michoacán around Coalcomán are usually considered part of the Sierra Madre del Sur. Ecology The range is noted for its very high biodiversity and large number of endemic species. The Sierra Madre del Sur pine-oak forests ecoregion occupies the higher reaches of ...

Its capital city is Oaxaca de Juárez. Oaxaca is in southwestern Mexico. It is bordered by the states of Guerrero to the west, Puebla to the northwest, Veracruz to the north, and Chiapas to the east. To the south, Oaxaca has a significant coastline on the Pacific Ocean. The state is best known for #Indigenous peoples, its indigenous peoples and cultures.

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 ...

Charadrahyla
''Charadrahyla'' is a genus of frogs in the family Hylidae. It is endemic to tropical southern Mexico. The generic name was derived from Greek ''charadra'' ("ravine") and ''Hyla'', in reference to the habits of these frogs. Accordingly, common name ravine treefrogs has been coined for the genus. Taxonomy and systematics This genus was erected in 2005 following a major revision of the Hylidae. It corresponds to the former ''Charadrahyla taeniopus, Hyla taeniopus'' group as defined by in 1970. The genus was originally diagnosed using molecular markers; no morphological synapomorphy, synapomorphies supporting the new genus could be identified. The sister taxon of ''Charadrahyla'' is ''Megastomatohyla''. Five of the species in this genus were previously placed in the genus ''Hyla''. Two species were later species description, described as new in this genus, and another two were transferred from ''Exerodonta'' in 2018 based on molecular data.
