White-headed Langur
The white-headed langur (''Trachypithecus leucocephalus'') is a critically endangered species of langur endemic to Guangxi, China. Taxonomy It was formerly considered a subspecies of the Cat Ba langur (''T. poliocephalus''), which is now thought to be endemic to Vietnam. Its taxonomy was previously uncertain; it has been considered a partially albinistic population of the François' langur (''T. francoisi''), a subspecies of Francois' langur,Bradon-Jones, D. 1995.

However, the IUCN Red List and American Society of Mammalogists now recognize it as a distinct species based on a 2007 study which split both species. Populations of this species in Chongzuo and Fusui display notable genetic divergence from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kunming Natural History Museum Of Zoology
The Kunming Natural History Museum of Zoology (昆明动物博物馆) is located on the campus of Kunming Institute of Zoology, Jiaochang East Road, Kunming, Yunnan, China. The museum is an important project of the Chinese Academy of Sciences Knowledge Innovation Program, and a joint project of the academy and Yunnan Provincial Government. The Kunming Natural History Museum of Zoology presents the diversity of fauna, past and present, of southwest China. It started earth construction in 2000 and opened to the public since November 2006. Various specimens collected by several generations of scientists in Kunming Institute of Zoology are fundamental basis for the establishment of the museum. A trio of dino-skeletons dominate the prehistoric exhibit on the first floor. These plant-eaters stomped around Yunnan about 200 million years ago. Though the biggest of the three is a cast, the smaller ones are genuine bones, exhumed from Yunnan's Lufeng Basin in the 1980s. Though the pre ...

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] |
Mammals Of China
This is a list of the mammal species recorded in China. There are 495 mammal species in China, of which thirteen are critically endangered, twenty-four are endangered, forty-seven are vulnerable, and seven are near threatened. One of the species listed for China can no longer be found in the wild.

Primates Of East Asia
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Trachypithecus
The lutungs, langurs, or leaf monkeys are a group of Old World monkeys in the genus ''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey"). Their range is much of Southeast Asia (northeast India, Vietnam, southern China, Borneo, Thailand, Java, and Bali). The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *''luCuŋ'' (which originally referred to the Formosan rock macaque); it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus ''Semnopithecus'', although some "lutungs" are now "langurs" again. Evolution Genetic analysis indicates that the ancestors of the modern species of lutung first differentiated from one another a little over 3 million years ago, during the late Pliocene. The various species alive today then diverged during the Pleistocene, presumably driven by habitat changes during the Ice Ages. The oldest fossils clearly identif ...

Hybridization (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show Heterosis, hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductive isolation, reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
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 ...

Poaching
Poaching has been defined as the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plant species. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock as in cattle raiding classifies as theft, not as poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their avail ...

Zuo River
The Zuo River (, vi, Tả Giang) is a river of Guangxi, China. It begins from the confluence of the Bằng River and Kỳ Cùng River near Longzhou and joins the You River ("Right River") near Nanning to form the Yong River. These rivers form part of the Pearl River system, which flows into the South China Sea near Guangzhou. The Zuo River historically was the main communication route in the area, linking the villages of the Zuo Valley to each other, to major Chinese centres to the north and east and to southern territories that are now part of Vietnam.

Evolutionarily Significant Unit
An evolutionarily significant unit (ESU) is a population of organisms that is considered distinct for purposes of conservation. Delineating ESUs is important when considering conservation action. This term can apply to any species, subspecies, geographic race, or population. Often the term "species" is used rather than ESU, even when an ESU is more technically considered a subspecies or variety rather than a biological species proper. In marine animals the term "stock" is often used as well. Definition Definitions of an ESU generally include at least one of the following criteria:Jeffrey Conner, Daniel Hartl. ''A Primer of Ecological Genetics''. 2004, # Current geographic separation, # Genetic differentiation at neutral markers among related ESUs caused by past restriction of gene flow, or # Locally adapted phenotypic traits caused by differences in selection. Criterion 2 considers the gene flow between populations, measured by FST. A high degree of differentiation between tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusui County
Fusui County is a county (China), county in the southwest of Guangxi, China. It is the easternmost county-level division of the prefecture-level city of Chongzuo.
