Quasipaa Shini
''Quasipaa shini'' (common names: spiny-flanked frog, Chinese paa frog) is a species of frog in the family Dicroglossidae. It is endemic to southern central China (Guangxi, Guizhou, Hunan, and Chongqing). Its natural habitats are rivers in subtropical moist lowland forests and montane forest at elevations of asl. It is threatened by over-collecting for human consumption and by habitat loss. ''Quasipaa shini'' are relatively large frogs. Males grow to a snout–vent length of about and females to . Tadpoles are up to about in length. Its specific name ''shini'' ("of Shin" in Latin) honours the biology professor (). The German zoologist Ernst Ahl Christoph Gustav Ernst Ahl (1 September 1898 – 14 February 1945) was a German Zoology, zoologist, born in Berlin. He was the director of the department of ichthyology and herpetology in the Museum für Naturkunde.

Ernst Ahl
Christoph Gustav Ernst Ahl (1 September 1898 – 14 February 1945) was a German Zoology, zoologist, born in Berlin. He was the director of the department of ichthyology and herpetology in the Museum für Naturkunde. He was also the editor in chief of the review ''Das Aquarium'' from 1927 to 1934. During World War II, Ahl fought in the ranks of the Wehrmacht - in Poland, North Africa and later Yugoslavia. He was executed while in refuge in Yugoslavia, after the partisans found out he was a German. He performed one of the first studies on Pogona, bearded dragons determining what genus they belong to. Ahl is commemorated in the scientific names of two species of lizards: ''Anolis ahli'' and ''Emoia ahli''.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Ahl", p. 3). The latter is a synonym of ''Emoia battersbyi''.

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of China
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] |

Quasipaa
''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 ...

Sun Yat-sen University
Sun Yat-sen University (, abbreviated SYSU and colloquially known in Chinese as Zhongda), also known as Zhongshan University, is a national key public research university located in Guangzhou, Guangdong, China. It was founded in 1924 by and named after Sun Yat-sen, a revolutionary and the founder of the Republic of China. Its main campus, commonly referred to as the South Campus, is located in Haizhu District, Guangzhou, inheriting the campus from the former Lingnan University (est. 1888).

Shinisaurus
The Chinese crocodile lizard (''Shinisaurus crocodilurus'') is a semiaquatic anguimorph lizard found only in cool forests in southeast China and northeast Vietnam. The Chinese crocodile lizard spends much of its time in shallow water or in overhanging branches and vegetation, where it hunts its prey of insects, snails, tadpoles, and worms. Individuals in captivity may be fed baby mice.Chinese Crocodile Lizard (''Shinisaurus crocodilurus''). The Sacramento Zoological Society. A rare and little-studied lizard, it is listed in Appendix I, which regulates international trade of specimens. This is the only species in the |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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 ...

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 ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

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 ...
