Protohynobius Puxiongensis
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 be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela, the sole surviving order from the group Caudata. ''Urodela'' is a scientific Latin term based on the Ancient Greek : ourà dēlē "conspicuous tail". ''Caudata'' is the Latin for "tailed ones", from : "tail". Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders never have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hynobiidae
The Asiatic salamanders (family Hynobiidae) are primitive salamanders found all over Asia, and in European Russia. They are closely related to the giant salamanders (family Cryptobranchidae), with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan, but their range also covers parts of China, Russia, Afghanistan and Iran. Hynobiid salamanders practice external fertilization, or spawning. And, unlike other salamander families which reproduce internally, male hynobiids focus on egg sacs rather than females during breeding. The female lays two egg sacs at a time, each containing up to 70 eggs. Parental care is common. A few species have very reduced lungs, or no lungs at all. Larvae can sometimes have reduced external gills if they live in cold and very oxygen-rich water. Fossils of hynobiids are known from the Miocene to the present in Asia and Eastern Europe, though fossils of Cryptobranchoids more closely related to ...

Endemic
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Sichuan
Sichuan is a province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet to the west. During antiquity, Sichuan was home to the kingdoms of Ba and Shu until their incorporation by the Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, and was heavily bombed. It was one of the last mainland areas captured ...

Hengduan Mountains
The Hengduan Mountains () are a group of mountain ranges in southwest China, southwest China that connect the southeast portions of the Tibetan Plateau with the Yunnan–Guizhou Plateau. The Hengduan Mountains are primarily large north-south mountain ranges that effectively separate lowlands in northern Myanmar from the lowlands of the Sichuan Basin. These ranges are characterized by significant vertical relief originating from the Indian subcontinent's collision with the Eurasian Plate, and further carved out by the major rivers draining the eastern Tibetan Plateau. These rivers, the Yangtze, Mekong, and Salween, are recognized today as the Three Parallel Rivers of Yunnan Protected Areas, Three Parallel Rivers UNESCO World Heritage Site. The Hengduan Mountains cover much of western present-day Sichuan province as well as the northwestern portions of Yunnan, the easternmost section of the Tibet Autonomous Region, and touching upon parts of southern Qinghai.

Qinghai-Tibet Plateau
The Tibetan Plateau, also known as the Qinghai–Tibet Plateau or Qingzang Plateau, is a vast elevated plateau located at the intersection of Central, South, and East Asia. Geographically, it is located to the north of Himalayas and the Indian subcontinent, and to the south of Tarim Basin and Mongolian Plateau. Geopolitically, it covers most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces, southern Xinjiang province in Western China, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti (Himachal Pradesh) as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately north to south and east to west. It is the world's highest and largest plateau above sea level, with an area of . With an average elevation exceeding and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is o ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Amphibian Species Of The World
''Amphibian Species of the World 6.2: An Online Reference'' (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range. The American Museum of Natural History hosts ''Amphibian Species of the World'', which is updated by herpetologist Darrel Frost. As of 2024, it contained more than 8700 species. History The Association of Systematics Collections (ASC) started this project in 1978 because the Convention on Trade in Endangered Species of Fauna and Flora (CITES) needed a database for animals. (The ASC later changed its name to Natural Science Collections Alliance.) The ASC's Stephen R. Edwards wrote ''Mammal Species of the World'' first and started ''Amphibian Species of the World'' second. Edwards decided to write about living amphibians because Richard G. Zweifel had just composed a large list of amphibian names and because experts from the Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
