Trachypithecus Poliocephalus
The Cat Ba langur (''Trachypithecus poliocephalus''), also known as the golden-headed langur, is a critically endangered species of langur endemic to Cát Bà Island, Vietnam. It is among the rarest primates in the world, and possibly the rarest primate in Asia, with population size estimated at less than 70 individuals. Taxonomy The Cat Ba langur was considered a subspecies of François' langur (''T. francoisi'') until 1995.Bradon-Jones, D. 1995.

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.

Cát Bà National Park
Cát Bà National Park is a World Heritage Site designated as a biosphere reserve in northern Vietnam. The park is part of Cát Bà Island in Hạ Long Bay and is administered by the city of Haiphong. The park is located approximately east of Hai Phong, covering about and comprising of land and of inshore water. The Cát Bà langur, also known as the white-headed langur (''Trachypithecus poliocephalus'') is resident within the park and is classified by the International Union for Conservation of Nature as a critically endangered primate; one of the rarest in the world. History Cát Bà National Park was established on 31 March 1986 under No.79/CP decision of the Council of Ministers of Vietnam (now the government). The park has been a popular tourist destination, since the mid-1990s with wealthy Chinese and Vietnamese tourists. The tourists created a demand for traditional medicine and development and logging led to the near extinction of the white-headed langur with numbe ...

Mammals Described In 1911
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Endemic Fauna Of Vietnam
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Primates Of Southeast 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 ...

Cúc Phương National Park
Cúc Phương National Park ( vi, Vườn quốc gia Cúc Phương) is located in Ninh Bình Province, in Vietnam's Red River Delta. Cuc Phuong was Vietnam's first national park and is the country's largest nature reserve. The park is one of the most important sites for biodiversity in Vietnam. History In 1960 Cúc Phương was made into a forest reserve and in 1962 Cúc Phương National Park was consecrated by President Ho Chi Minh. Human habitation in Cúc Phương dates back long before the park’s creation, 7,000-12,000 years ago. Artifacts from that time have been found in numerous caves within the park, including human graves, stone axes, pointed bone spears, oyster shell knives, and tools for grinding. In 1789 the Quen Voi section of the park was the site of a major battle in the civil war between Nguyễn Huệ and Thăng Long. More recently, conflicts have emerged between the government and 2,500 Muong ethnic minority tribesmen who live, farm, and hunt in the pa ...

The World's 25 Most Endangered Primates
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
