Cream-backed Poison Frog
The cream-backed poison frog (''Hyloxalus subpunctatus'') is a species of frog in the family Dendrobatidae endemic to Colombia. Its natural habitats are subtropical or tropical, high-altitude grassland, shrub-dominated wetlands, swamps, intermittent freshwater marshes, rural gardens, urban areas, and heavily degraded former forests. The cream-backed poison frog is one of the less-toxic of the family. It has undergone several name changes since its discovery. Originally called ''Dendrobates subpunctatus'', its name was changed to ''Colostethus subpuctatus'' once the family Dendrobatidae underwent a division of species and genera other than ''Dendrobates'' were coined. Recently, minor skeletal differences have separated the cream-backed poison frog from the rocket frogs, and placed it in another genus entirely, ''Hyloxalus''. Toxin Like many of the genus ''Hyloxalus'', ''H. subpunctatus'' possesses fairly weak toxins, compared to those of other dendrobatids. It may be one of the ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrobates
''Dendrobates'' is a genus of poison dart frogs native to Central and South America. It once contained numerous species, but most originally placed in this genus have been split off into other genera such as ''Adelphobates'', ''Ameerega'', ''Andinobates'', ''Epipedobates'', ''Excidobates'', ''Oophaga'', ''Phyllobates'' and ''Ranitomeya'' (essentially all the brightly marked poison dart frogs; i.e. excluding the duller genera in the family like ''Colostethus'' and ''Hyloxalus ''Hyloxalus'' is a genus of poison dart frogs, family Dendrobatidae.

Amphibians Of Colombia
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 ...

Páramo
Páramo () can refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ecuador) ter ...

Boyacá Department
Boyacá () is one of the thirty-two departments of Colombia, and the remnant of Boyacá State, one of the original nine states of the "United States of Colombia". Boyacá is centrally located within Colombia, almost entirely within the mountains of the Eastern Cordillera to the border with Venezuela, although the western end of the department extends to the Magdalena River at the town of Puerto Boyacá. Boyacá borders to the north with the Department of Santander, to the northeast with the Bolivarian Republic of Venezuela and Norte de Santander, to the east with the departments of Arauca and Casanare. To the south, Boyacá borders the department of Cundinamarca and to the west with the Department of Antioquia covering a total area of . The capital of Boyacá is the city of Tunja. Boyacá is known as "The Land of Freedom" because this region was the scene of a series of battles which led to Colombia's independence from Spain. The first one took place on 25 July 1819 in ...

Altiplano Cundiboyacense
The Altiplano Cundiboyacense () is a high plateau located in the Eastern Cordillera of the Colombian Andes covering parts of the departments of Cundinamarca and Boyacá. The altiplano corresponds to the ancient territory of the Muisca. The Altiplano Cundiboyacense comprises three distinctive flat regions; the Bogotá savanna, the valleys of Ubaté and Chiquinquirá, and the valleys of Duitama and Sogamoso. The average altitude of the altiplano is about above sea level but ranges from roughly to . Etymology ''Altiplano'' in Spanish means "high plain" or "high plateau", the second part is a combination of the departments Cundinamarca and Boyacá. Geography The limits of the Altiplano are not strictly defined. The high plateau is enclosed by the higher mountains of the Eastern Ranges, with the Sumapaz mountains in the south and Chingaza to the east. The Tenza Valley is located to the east of the Altiplano and the Ocetá Páramo and Chicamocha Canyon are situated to the ... [...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'' †...

Hyloxalus
''Hyloxalus'' is a genus of poison dart frogs, family Dendrobatidae. The genus is distributed in Central and South America, from Panama south to Peru (along the Pacific coast), along with Venezuela, Colombia, and Ecuador. They also inhabit the eastern foothills of the Andes in Bolivia to Venezuela, east to the upper Amazon Basin. Description ''Hyloxalus'' are small to moderate-size frogs, ranging from about in snout–vent length. Most species have cryptic, brown, gray, or black dorsal coloration, but some have conspicuous, bright colors (e.g., ''Hyloxalus azureiventris''). A pale oblique lateral stripe is always present. Toe webbing is absent in most species but is present in some species and can even be extensive. Fingers bear narrow to moderately expanded discs. Reproduction Most species deposits their eggs in terrestrial nests and transport the tadpoles to pools on the forest floor or in backwaters of streams.
