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, a valid species (''T. leucocephalus''), or a subspecies, ''T. poliocephalus leucocephalus''. However, the IUCN Red List assessors and American Society of Mammalogists now recognize it as a distinct species based on a 2007 study which split both species. Populations of the white-headed langur in Chongzuo and Fusui County display notable genetic divergence from the rest of the species, and it has thus been proposed they be treated as evolutionarily significant units. Description The white-headed langur is blackish in color with white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cát Bà National Park
Cát Bà National Park ( Vietnamese: ''Vườn Quốc Gia Cát Bà'') 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Endemic Fauna Of Vietnam
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 becomin ...

Mammals Of Vietnam
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Primates Of Southeast Asia
Primates is an order (biology), order of mammals, which is further divided into the Strepsirrhini, strepsirrhines, which include lemurs, galagos, and Lorisidae, lorisids; and the Haplorhini, haplorhines, which include Tarsiiformes, tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial animal, terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among Canopy (biology), tree tops, including large brain sizes, binocular vision, color vision, Animal communication, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (in most but not all) that enable better grasping and dexterity. 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 ...

Trachypithecus
''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey") is a genus of Old World monkeys containing species known as lutungs, langurs, or leaf monkeys. 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 ...

Cúc Phương National Park
Cúc Phương National Park () is located in Ninh Bình Province, in Vietnam's Red River Delta. Cuc Phuong was Vietnam's first Protected areas of Vietnam, 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 people, 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 ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...
