Metaphrynella
''Metaphrynella'' is a small genus of microhylid frogs from the southern Malay Peninsula and Borneo. They are sometimes known as the Borneo treefrogs or tree hole frogs. The common name refers to the microhabitat of these frogs: males call from tree holes and tadpoles develop in the water contained in those holes. Description ''Metaphrynella'' are small, arboreal frogs that have plump bodies and adhesive finger and toe tips. Taxonomy ''Metaphrynella'' may be paraphyletic, as molecular dataDe Sá, R.

Metaphrynella Sundana
''Metaphrynella sundana'' (Borneo treefrog or Bornean tree hole frog) is a species of frog in the family Microhylidae. It is endemic to Borneo and found in Brunei, Indonesia, and Malaysia. Description ''Metaphrynella sundana'' are small frogs; adults measure up to about in snout–vent length. The body is stocky and the limbs are moderately short. Skin has rounded tubercles that are larger on the sides. Colouration and texture show considerable variation. The male has a median subgular vocal sac. Males call at night from tree holes that are about meters above the ground. Males are able to adjust their call to the resonance frequency of the tree hole they call from. Habitat and conservation The species' natural habitats are lowland primary rainforests to about asl. It is a common frog in primary and secondary rainforests. Reproduction takes place in tree holes with water. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction ...

Metaphrynella Pollicaris
''Metaphrynella pollicaris'' (common name: Malaysian treefrog or Malaysian tree-hole frog) is a species of frog in the family Microhylidae. It is endemic to Peninsular Malaysia. Description Males measure and females in snout–vent length. Dorsum is dark olive-brown above, with a variable patterning. Tympanum is hidden. Finger tips are expanded into large disks. Habitat and conservation The species' natural habitats are evergreen rainforest and forest edges. It lives in hollows in tree trunks and bamboo, where it also reproduces. While it is secretive, the male call is distinctive and makes it surveyable. Based on the calls, it is abundant where it occurs. It abundance seems to be limited by the availability of tree holes. It can occur as low as asl, but is more common from about upwards. It could be locally threatened by habitat loss, although it may benefit from habitat clearing that encourages the growth of giant bamboos, providing it with its microhabitat In e ...

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt.

Kaloula
''Kaloula'' is a genus of microhylid frogs found in southern and eastern Asia. They are sometimes known as the Asian narrowmouth toads. Species The genus currently has at least 19 species. Some sources also recognize ''Kaloula macrocephala'' Bourret, 1942 as a valid species, whereas the Amphibian Species of the World treats it as a synonym of ''Kaloula pulchra''. 5 new species have been described since 2000, and there are unnamed species yet to be described. ''Kaloula pulchra'', ''Kaloula picta'', and ''Kaloula borealis'' are the most widespread and commonly found varieties, often living near human settlements. Blackburn, et al. (2013) lists several ''Kaloula'' varieties that are likely to be new, previously undescribed species. *''Kaloula sp. nov. Palawan'': Closely related to ''Kaloula baleata''. Recorded in Palawan. *''Kaloula sp. nov. Sulawesi'': Closely related to ''Kaloula baleata''. Recorded in the Togian Islands (Batudaka Island), Central Sulawesi, and North Sulawesi ...

Phrynella
''Phrynella'' is a genus of frogs in the family Microhylidae. It is monotypic, being represented by the single species, ''Phrynella pulchra''. It is found in Indonesia, Malaysia, and Thailand. Its natural habitats are subtropical or tropical moist lowland forests and intermittent freshwater marshes. 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 ....

Sister Clade
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Ramanella
''Uperodon'' is a genus of microhylid frogs. They occur in South Asia (Pakistan, India, Sri Lanka, Bhutan, Nepal, and Bangladesh) and Myanmar. ''Uperodon'' reached its current composition in 2016 when the genus Ramanella was brought into its synonymy. The common names of these frogs are globular frogs and balloon frogs in reference to their stout appearance, or dot frogs, the last specifically referring to the former Ramanella. ''Uperodon'' includes burrowing frogs that eat ants and termites. Species There are 12 recognized species: * ''Uperodon anamalaiensis'' (Rao, 1937) * ''Uperodon globulosus'' (Günther, 1864) * ''Uperodon montanus'' (Jerdon, 1853) * ''Uperodon mormoratus'' (Rao, 1937) * ''Uperodon nagaoi'' (Manamendra-Arachchi and Pethiyagoda, 2001) * ''Uperodon obscurus'' (Günther, 1864) * ''Uperodon palmatus'' (Parker, 1934) * ''Uperodon rohani'' Garg, Senevirathne, Wijayathilaka, Phuge, Deuti, Manamendra-Arachchi, Meegaskumbura, and Biju, 2018 * ''Uperodon systoma'' (S ...

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 in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
