Quasipaa Courtoisi
''Quasipaa'' is a genus of frogs in the family Dicroglossidae. The genus has no established common name, but many individual species are referred to as ''spiny frogs''. They occur in East and Southeast Asia, from Thailand and Cambodia to southern and eastern China. Taxonomy ''Quasipaa'' was first proposed as a subgenus of ''Paa'' (now considered to belong to ''Nanorana''). It was subsequently raised to the level of genus, and molecular phylogenetic analyses have corroborated the monophyly of ''Quasipaa''. Many individual species were originally described in genus ''Rana''. Even after splitting the very wide ''Rana'' into smaller taxa, frogs now in ''Quasipaa'' continued to belong to the true frog family (Ranidae), at times as subfamily Dicroglossinae, until Dicroglossinae was raised to the family level (i.e., Dicroglossidae). The taxonomy of Dicroglossidae is far from settled yet. Species There are 11 species in this genus: Conservation and use The International Union for ...

Quasipaa Exilispinosa
''Quasipaa exilispinosa'' is a species of frog in the family Dicroglossidae. It is known under many common names, including Hong Kong spiny frog, common spiny frog, lesser spiny frog, little spiny frog, and Hong Kong paa frog. It has a patchy distribution in southern China including Hong Kong. Its natural habitats are subtropical hill streams in forests or shrublands, and sometimes also seepages, stream-fed marshes, and forests. It is threatened by over-collecting for human consumption and by habitat loss. As hinted by common names "lesser" or "little" spiny frog, ''Quasipaa exilispinosa'' are relatively small among ''Quasipaa'' and the related frogs. Males grow to a snout–vent length of about and females to . Tadpole A tadpole is the larval stage in the biological life cycle of an amphibian.

Dicroglossinae
The frog family Dicroglossidae occurs in tropical and subtropical regions of Asia and Africa, with most genera and species being found in Asia. The common name of the family is fork-tongued frogs. The Dicroglossidae were previously considered to be a subfamily in the family Ranidae, but their position as a family is now well established. Subfamilies and genera The two subfamilies contain 213 species in 13–15 genera, depending on the source.

Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon is Vulnerable when it is not critically endangered or Endangered but ...

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quasipaa Yei
''Quasipaa yei'', or Ye's spiny-vented frog, is a species of frog in the family Dicroglossidae. It is endemic to China where it is known from the Dabie Mountains that straddle the border between Hubei, Henan, and Anhui provinces. Its type locality is in Shengcheng County in Jiyuan City, Henan. Its natural habitats are temperate rivers with surrounding forests. It is potentially threatened by habitat loss. The taxonomic position of this species has been in flux. Originally described as '' Paa (Feirana) yei'' in 2002, it has already been placed in genera ''Feirana'' (if raised from subgenus to genus), ''Yerana'', and ''Nanorana'', at least, before arriving at genus ''Quasipaa''. In medicine The species is used in development of a drug called Rhodopsin Rhodopsin, also known as visual purple, is a protein encoded by the RHO gene and a G-protein-coupled receptor (GPCR).

Quasipaa Verrucospinosa
''Quasipaa verrucospinosa'' is a species of frog in the family Dicroglossidae. It is found in Laos, Vietnam, and Yunnan, China. It occurs in and around streams (its breeding habitat) in hill and lower montane evergreen forests. It is believed to be relatively common, but it is threatened by collection for consumption and—presumably—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 ... driven by logging, causing degradation of forest habitat and stream sedimentation.

Quasipaa Spinosa
''Quasipaa spinosa'' is a species of frog in the family Dicroglossidae. It is known under many common names, including Chinese spiny frog, giant spiny frog, Chinese edible frog, and spiny paa frog. Its names refer to the distinctive characteristics of the species, relatively large size and the spiny chest of male frogs. Giant in frog terms only, it can nevertheless grow to lengths above ; this makes it the largest frog in Hong Kong. Taxonomy Recent molecular phylogenetic analyses have suggested that ''Quasipaa spinosa'' is split in three distinct lineages; the nominal ''Quasipaa spinosa'' may thus represent a cryptic species complex. The lineages are geographically distinct; one lineage is found in Yunnan, another one in southeastern China (Anhui, Zhejiang, northern Fujian, and Jiangxi), and the third one in south-central China (southern Fujian, Jiangxi, Hunan, Guangdong, and Guangxi). In this analysis, '' Quasipaa exilispinosa'' is nested within ''Quasipaa spinosa''. It's sibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
