Oreolalax Puxiongensis
''Oreolalax puxiongensis'' (Puxiong toothed toad) is a species of amphibian in the family Megophryidae. It is endemic to China where it is only known from two locations in Yuexi County, Sichuan, including Puxiong (普雄镇), its type locality. It inhabits marshes, pools, small streams and the surrounding subtropical forest. It is threatened by habitat loss. ''Oreolalax puxiongensis'' is the smallest among the ''Oreolalax'': males grow to about in snout-vent length and females to about . 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 i ...s are in length.

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megophryidae
Megophryidae, commonly known as goose frogs, is a large family of frogs native to the warm southeast of Asia, from the Himalayan foothills eastwards, south to Indonesia and the Greater Sunda Islands in Maritime Southeast Asia, and extending to the Philippines. Fossil remains are also known from North America. it encompasses 246 species of frogs divided between five genera. For lack of a better vernacular name, they are commonly called megophryids. Morphology The megophryids are notable for their camouflage, especially those that live in forests, which often look like dead leaves. The camouflage is accurate to the point of some having skin folds that look like leaf veins, and at least one species, the long-nosed horned frog (''Megophrys montana'') has sharp projections extending past the eye and nose, which disguise the frog shape. Megophryids range in size from in length. The adults' tongues are noticeably paddle-shaped. Their tadpoles can be found in a variety of waters, but e ...

Endemism
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] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

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 ...

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 ...

Puxiong Salamander
The Puxiong salamander (''Pseudohynobius puxiongensis'') is a species of salamander in the family Hynobiidae, endemic to China. It is only known from the vicinity of its type locality, in Puxiong (普雄镇), in Yuexi County, Sichuan Province. The area belongs to the Hengduan Mountains that form the southeastern part of the Qinghai-Tibet Plateau. The Puxiong salamander is a relatively small salamander with a slender body form. History of discovery and taxonomic position The Puxiong salamander was first described in 2000 as ''Protohynobius puxiongensis'', based on a single specimen collected in 1965. Because of a characteristic interpreted as primitive (internasal bone), a new monotypic genus, ''Protohynobius'', in its own subfamily, Protohynobiinae, was established. However, field effort in 2007–2009 revealed new animals that allowed a more detailed analysis. These suggested the holotype from 1965 was slightly unusual, as later specimens did not have an internasal bone while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreolalax
''Oreolalax'' is a genus of amphibian in the family Megophryidae. They are mostly endemic to southwestern China, with one species in northern Vietnam ('' Oreolalax sterlingae''), and possibly extending into adjacent Laos. There is also a population in Arunachal Pradesh (Northeast India) that has not yet been assigned to a species, although it might rather be a '' Scutiger''. Species The genus contains the following 19 species: Endemic ranges Many ''Oreolalax'' species are endemic to highly restricted geographical areas in the Eastern Himalayas, especially in Sichuan, China. The ranges often overlap with those of '' Scutiger'' species. *Yunnan, China ** ''Oreolalax granulosus'': Ailao Mountains, Jingdong County, Yunnan ** ''Oreolalax jingdongensis'': Ailao Mountains, Jingdong County, Yunnan *Sichuan, China ** '' Oreolalax nanjiangensis'': Mount Guangwu (光雾山), Nanjiang County, Sichuan ** '' Oreolalax chuanbeiensis'': Pingwu County and Mao County, Sichuan ** ''Oreolalax ...
