Mammals Of Cambodia
The wildlife of Cambodia is very diverse with at least 162 mammal species, 600 bird species, 176 reptile species (including 89 subspecies), 900 freshwater fish species, 670 invertebrate species, and more than 3000 plant species. A single protected area, Keo Seima Wildlife Sanctuary, is known to support more than 950 total species, including 75 species that are listed as globally threatened on the IUCN Red List. An unknown amount of species remains to be described by science, especially the insect group of butterflies and moths, collectively known as lepidopterans.REPORT 4 Fauna and flora diversity studies in Botum Sakor National Park, Cambodia April 2005 – September 2009 Frontier Cambod ...

Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Conservation Organizations
An environmental organization is an organization coming out of the conservation or environmental movements that seeks to protect, analyse or monitor the environment against misuse or degradation from human forces. In this sense the environment may refer to the biophysical environment or the natural environment. The organization may be a charity, a trust, a non-governmental organization, a governmental organization or an intergovernmental organization. Environmental organizations can be global, national, regional or local. Some environmental issues that environmental organizations focus on include pollution, plastic pollution, waste, resource depletion, human overpopulation and climate change. Intergovernmental organizations Global organization in the world * Global Alliance on Health and Pollution (GAHP) * Global Biodiversity Information Facility (GBIF) * School strike for climate or Fridays for Future (FFF) * Global Green Growth Institute (GGGI) * Intergovernmental Panel ...

Gaur
The gaur (''Bos gaurus''; ) is a large bovine native to the Indian Subcontinent and Southeast Asia, and has been listed as Vulnerable species, Vulnerable on the IUCN Red List since 1986. The global population was estimated at a maximum of 21,000 mature individuals in 2016, with the majority of those existing in India. It is the largest species among the wild cattle and the Bovidae. The domesticated ''gayal'' or ''mithun'' originated partly from the wild gaur and is most common in the border regions of Northeast India (Assam, Manipur, Nagaland) and Bangladesh with Myanmar and Yunnan, China.Simoons, F. J. (1984). ''Gayal or mithan''. In: Mason, I. L. (ed.) ''Evolution of Domesticated Animals''. Longman, London. Pages 34–38. Etymology The Sanskrit word means 'white, yellowish, reddish'. The Sanskrit word means a kind of water buffalo. The Hindi word means 'fair-skinned, fair, white'. Taxonomy ''Bison gaurus'' was the scientific name proposed by Charles Hamilton Smith ...

Banteng
The banteng (''Bos javanicus''; ), also known as tembadau, is a species of wild Bovinae, bovine found in Southeast Asia. The head-and-body length is between . Wild banteng are typically larger and heavier than their Bali cattle, domesticated counterparts, but are otherwise similar in appearance. The banteng shows extensive sexual dimorphism; adult bulls are generally dark brown to black, larger and more sturdily built than adult cows, which are thinner and usually pale brown or chestnut red. There is a big white patch on the Rump (animal), rump. Horn (anatomy), Horns are present on both sexes, and are typically long. Three subspecies are generally recognised. Banteng are Cathemerality, active during the day as well as at night, though Nocturnality, activity at night is more in areas frequented by humans. Herds comprise two to forty individuals, and generally a single bull. Being herbivorous, banteng feed on vegetation such as grasses, sedges, Shoot (botany), shoots, leaves, ...

Muntjac
Muntjacs ( ), also known as the barking deer or rib-faced deer, (URL is Google Books) are small deer of the genus ''Muntiacus'' native to South Asia and Southeast Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. Most are listed as least-concern species or Data Deficient by the International Union for Conservation of Nature (IUCN), although others such as the black muntjac, Bornean yellow muntjac, and giant muntjac are Vulnerable species, vulnerable, Near-threatened species, near threatened, and critically endangered, respectively. Name The present name is a borrowing of the latinisation of names, Latinized form of the Dutch language, Dutch , which was borrowed from the Sundanese language, Sundanese ''mencek'' (). The Latin form first appeared as in E.A.W. von Zimmerman, Zimmerman in 1780. An erroneous alternative name of ''Mastreani deer'' has its origins in a Vandalism on Wik ...

Dhole
The dhole ( ; ''Cuon alpinus'') is a canid native to South, East and Southeast Asia. It is anatomically distinguished from members of the genus ''Canis'' in several aspects: its skull is convex rather than concave in profile, it lacks a third lower molar, and the upper molars possess only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, with its range also extending into Europe (with a single putative, controversial record also reported from North America) but became restricted to its historical range 12,000–18,000 years ago. It is now extinct in Central Asia, parts of Southeast Asia, and possibly the Korean peninsula and Russia. Genetic evidence indicates that the dhole was the result of reticulate evolution, emerging from the hybridization between a species closely related to genus ''Canis'' and one from a lineage closely related to the African wild dog (''Lycaon pictus''). The dhole is a highly social ani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eld's Deer
Eld's deer (''Rucervus eldii'' or ''Panolia eldii''Pitraa, Fickela, Meijaard, Groves (2004). ''Evolution and phylogeny of old world deer.'' Molecular Phylogenetics and Evolution 33: 880–895.), also known as the thamin or brow-antlered deer, is an Endangered species of deer endemic to South and Southeast Asia. It inhabits wetlands and marshlands. It is active during the day and mates from October to the end of December. Three subspecies are recognised. All three are threatened by hunting and deforestation. Taxonomy The species was first described by John McClelland in 1840 based on specimens obtained in Manipur, India. It was described more detailed by Percy Eld in 1841; it was suggested to call the deer ''Cervus Eldii''. McClelland coined the scientific name ''Cervus (Rusa) frontals'' in 1843. In 1850, John Edward Gray proposed the name ''Panolia eldii'' for the deer. It has recently been proposed that it should be moved back to the genus ''Panolia'' on the basis of recent ge ...

Extirpation
Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with extinction, global extinctions. Local extinctions mark a change in the ecology of an area. It has sometimes been followed by a replacement of the species taken from other locations, such as with wolf reintroduction. Discussion Glacial period, Glaciation is one factor that leads to local extinction. This was the case during the Quaternary glaciation, Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extinct from islands over time; this can be either local extinction if the species also occurs elsewhere, or in cases of endemism, island endemism, outright ex ...

Kouprey
The kouprey (''Bos sauveli''), also known as the forest ox and grey ox, is a possibly extinct species of forest-dwelling wild Bovinae, bovine native to Southeast Asia. It was first scientifically described in 1937. The name ''kouprey'' is derived from the Khmer language and means "forest ox". The kouprey was defined as the national mammal of Cambodia in 2005. The kouprey is listed as Critically Endangered and possibly extinct on the IUCN Red List. The last confirmed sighting of a wild individual took place in 1969. Taxonomy and phylogeny The kouprey was Species description, described by Achille Urbain in 1937 based on an adult individual that was caught in northern Cambodia and was kept at the Paris Zoological Park. In 2006, a comparison of mitochondrial DNA sequences indicated that the kouprey may be a hybrid between zebu and banteng. However, the authors of the study rescinded their conclusion. In 2021, it was established that the kouprey represents a distinct species unrelat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
