Huangshan Softshell Turtle
The Huangshan softshell turtle or horse-hoof softshell turtle (''Pelodiscus huangshanensis'') is a species of turtle in the family Trionychidae. It is endemic to China, where it is found only in southern Anhui Province, in the Huangshan range. Taxonomy Prior to 2021, populations of this species were considered conspecific with the more widespread Chinese softshell turtle (''P. sinensis''), which was thought to be the only native softshell turtle in the province. However, local people knew about the existence of this species over a millennium prior. Folk songs and poems noted a second form of softshell turtle in the Huangshan range, referred to as the "horse-hoof softshell turtle" or ''mǎ tí biē'' (马蹄鳖). Phylogenetic evidence of these populations found them to be a distinct species most closely related to the Hunan softshell turtle (''P. axenaria'') as well as an undescribed ''Pelodiscus'' from Jiangxi. It was accepted as a distinct species by the Turtle Taxonomy Workin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jiangxi
Jiangxi (; ; formerly romanized as Kiangsi or Chianghsi) is a landlocked province in the east of the People's Republic of China. Its major cities include Nanchang and Jiujiang. Spanning from the banks of the Yangtze river in the north into hillier areas in the south and east, it shares a border with Anhui to the north, Zhejiang to the northeast, Fujian to the east, Guangdong to the south, Hunan to the west, and Hubei to the northwest. The name "Jiangxi" is derived from the circuit administrated under the Tang dynasty in 733, Jiangnanxidao (; Gan: Kongnomsitau). The abbreviation for Jiangxi is "" (; Gan: Gōm), for the Gan River which runs across from the south to the north and flows into the Yangtze River. Jiangxi is also alternately called ''Ganpo Dadi'' () which literally means the "Great Land of Gan and Po". After the fall of the Qing dynasty, Jiangxi became one of the earliest bases for the Communists and many peasants were recruited to join the growing people's rev ...

Reptiles Of China
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated aroun ...

Turtles Of Asia
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat ...

Pelodiscus
''Pelodiscus'' is a genus of turtles in the family Trionychidae, the softshells. Based on genetic and morphological analysis there are seven valid species. They are native to Eastern Asia, ranging from the Amur region, south through China and Korea, as far south as Vietnam. Populations in Japan are thought to likely originate from historic human introductions. Phylogenetic studies have recovered a high diversity of ''Pelodiscus'' genotypes in China, some of which may correspond to distinct species. However, the millennia-old practice of farming ''Pelodiscus'' for consumption, especially in large-scale turtle farms since the late 20th century, is thought to threaten these lineages due to hybridization with farmed individuals.

Captive Breeding
Captive breeding, also known as captive propagation, is the process of plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, over hunting or fishing, pollution, predation, disease, and parasitism. For many species, relatively little is known about the conditions needed for successful breeding. Information about a species' reproductive biology may be critical to the success of a captive breeding program. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions. History Captive breeding techniques began with the first huma ...

Qiantang River
The Qiantang River, formerly known as the Hangchow River and alternatively romanised as the Tsientang River, is a river in East China. An important commercial artery, it runs for through Zhejiang, passing through the provincial capital Hangzhou before flowing into the East China Sea via Hangzhou Bay south of Shanghai. Its original name, the "Zhe River" or "Zhe Jiang", is the origin of the name of Zhejiang province. The river is also known, along with Hangzhou Bay, for having the world's largest tidal bore, a phenomenon where leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current. Etymology Its upper stretch near the AnhuiJiangxi border is also known as the Xin'an River (, "Newly Peaceful"); its middle stretch through the mountains of Zhejiang is also known as the Fuchun River (, "Abundant Spring River"); and the former name of its lower stretchthe Zhe () or Crooked Rive ...

Turtle Taxonomy Working Group
The Turtle Taxonomy Working Group (TTWG) is an informal working group of the IUCN/SSC Tortoise and Freshwater Turtle Specialist Group (TFTSG). It is composed of a number of leading turtle taxonomist In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given ...s, with varying participation by individual participants over the years, some dropping out and others joining. The TTWG has produced an annual checklist of living and recently extinct turtles since 2007, deliberates on proposed changes to turtle taxonomy, and describes its consideration whether to accept, reject, or suspend adoption of proposed changes in a series of annotations to the checklist. Recent versions of the checklist have included full primary synonymies and citations to all original descriptions of recent turtle taxa, as well ...

Chinese Softshell Turtle
The Chinese softshell turtle (''Pelodiscus sinensis'') is a species of softshell turtle that is native to China (Inner Mongolia to Guangxi, including Hong Kong) and Taiwan, with records of escapees—some of which have established introduced populations—in a wide range of other Asian countries, as well as Spain, Brazil and Hawaii. Populations native to Northeast China, Russia, Korea and Japan were formerly included in this species, but are now regarded as separate as the northern Chinese softshell turtle (''P. maackii''). Furthermore, localized populations in Guangxi and Hunan (where the Chinese softshell turtle also is present), as well as Vietnam, are recognized as the lesser Chinese softshell turtle (''P. parviformis'') and Hunan softshell turtle (''P. axenaria''). The Chinese softshell turtle is a vulnerable species, threatened by disease, habitat loss, and collection for food such as turtle soup. Additionally, millions are now farmed, especially in China, to support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huangshan
Huangshan (),Bernstein, pp. 125–127. Literal translation, literally meaning the Yellow Mountain(s), is a mountain range in southern Anhui Provinces of China, Province in eastern China. It was originally called “Yishan”, and it was renamed because of a legend that Emperor Xuanyuan once made alchemy here. Vegetation on the range is thickest below , with trees growing up to the treeline at . The area is well known for its scenery, sunsets, peculiarly-shaped granite peaks, Huangshan pine trees, hot springs, winter snow and views of the clouds from above. Huangshan is a frequent subject of traditional Chinese paintings and Chinese literature, literature, as well as modern photography. It is a UNESCO World Heritage Site and one of Tourism in China#Famous sites, China's major tourist destinations.
