Phyllomedusa Venusta
''Phyllomedusa venusta'' is a species of frog in the subfamily Phyllomedusinae, found in Colombia and Panama. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forests. 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 ....

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] |
Phyllomedusinae
Phyllomedusinae is a subfamily of hylid tree frogs found in the Neotropics commonly called leaf frogs. Formerly, they were often considered as their own family, Phyllomedusidae. The subfamily is considered to be the sister group to the Australian treefrogs (Pelodryadinae), a subfamily of frogs known from Australia and New Guinea, despite being very geographically separated from them. The common ancestor of both subfamilies is thought to have lived in early Cenozoic South America, where the Phyllomedusinae still live, with the two families diverging from one another during the Eocene. The ancestors of Pelodryadinae likely colonized Australasia from South America via Antarctica, which at the time was not yet frozen over. The clade comprising both subfamilies is sister to the Hylinae, from which they diverged in the early Paleogene. Taxonomy The subfamily Phyllomedusidae contains the following genera: * ''Agalychnis'' (14 species) * ''Callimedusa'' (six species) * ''Cruziohyla' ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

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 ...

Phyllomedusa
''Phyllomedusa'' is a genus of tree frogs in the subfamily Phyllomedusinae found in tropical and subtropical South America (south to northern Argentina) and Panama. It has 16 recognised species. Taxonomy The following species are recognised in the genus ''Phyllomedusa'': * ''Phyllomedusa bahiana'' * ''Phyllomedusa bicolor'' - giant leaf frog * ''Phyllomedusa boliviana'' * ''Phyllomedusa burmeisteri'' - Burmeister's leaf frog * '' Phyllomedusa camba'' * ''Phyllomedusa chaparroi'' * '' Phyllomedusa coelestis'' * '' Phyllomedusa distincta'' * ''Phyllomedusa iheringii'' * ''Phyllomedusa neildi'' * ''Phyllomedusa sauvagii'' - waxy monkey leaf frog * '' Phyllomedusa tarsius''- tarsier leaf frog * '' Phyllomedusa tetraploidea'' * ''Phyllomedusa trinitatis'' * ''Phyllomedusa vaillantii'' - white-lined leaf frog * '' Phyllomedusa venusta'' Several other species formerly included in this genus are now placed in two other phyllomedusid genera: ''Callimedusa'' and ''Pithecopus''.

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 ...

Amphibians Of Panama
This is a list of amphibians found in Panama. 205 amphibian species have been registered in Panama, which are grouped in 3 orders: Caecilians (Gymnophiona), Salamanders (Caudata) and Frogs and Toads (Anura). This list is derived from the database listing of AmphibiaWeb.AmphibiaWeb 2012 25 species are critically endangered(CR), 16 species are endangered (EN) and 6 species are vulnerable (VU). One species has recently (September 2016) gone extinct with the last individual in captivity dying, and with not a single specimen seen nor heard in the wild for over a decade. Several other species might also be extinct with no specimen found for decades. The following tags are used to highlight specific species' conservation status as assessed by the IUCN: Caecilians (Gymnophiona) Caeciliidae Order: Gymnophiona. Family: Caeciliidae *'' Caecilia isthmica'' (DD) *'' Caecilia leucocephala'' (LC) *'' Caecilia nigricans'' (LC) *'' Caecilia tentaculata'' (LC) *'' Caecilia volcani'' (DD) *'' ...
