Western Hoolock Gibbon
The western hoolock gibbon (''Hoolock hoolock'') is a primate from the gibbon family, Hylobatidae. The species is found in Assam, Mizoram, and Meghalaya in India, Bangladesh, and Myanmar west of the Chindwin River. Classification Mootnick and Groves stated that hoolock gibbons do not belong in the genus ''Bunopithecus'', and placed them in a new genus, ''Hoolock''. This genus was argued to contain two and later three distinct species, which were previously thought to be subspecies: ''H. hoolock'', '' H. leuconedys'', and '' H. tianxing''. A larger evolutionary distance was later found to exist between these three species and the white-handed gibbons than between bonobos and chimpanzees. A new subspecies of the western hoolock gibbon has been described recently from northeastern India, which has been named the Mishmi Hills hoolock gibbon, ''H. h. mishmiensis''. Vocalisation Like other gibbons, hoolock gibbon pairs produce a loud, elaborate song, usually as a duet from the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Harlan
Richard Harlan (September 19, 1796 – September 30, 1843) was an American paleontologist, anatomist, and physician. He was the first American to devote significant time and attention to vertebrate paleontology and was one of the most important contributors to the field in the early nineteenth century. His work was noted for its focus on objective descriptions, taxonomy and nomenclature. He was the first American to apply Linnaean names to fossils. Biography Harlan was born in Philadelphia on September 19, 1796, to Joshua Harlan, a wealthy Quaker merchant, and his wife Sarah Hinchman Harlan, one of their ten children. He was three years older than his brother Josiah Harlan, who would become the first American to visit Afghanistan. Harlan graduated in medicine from the University of Pennsylvania in 1818 after taking time off during his studies to spend a year sailing to India as a ship's surgeon for the British East India Company. In 1821 he was elected professor of comparative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Hoolock Gibbon
The eastern hoolock gibbon (''Hoolock leuconedys'') is a primate from the gibbon family, Hylobatidae. It is one of three species of hoolock gibbon. This species is found in east of the Chindwin River, such as the Mahamyaing Wildlife Sanctuary, and in south west Yunnan of China. Recent study published in April, 2021, in Internaltional Journal of Primatology confirmed that this species is not found in India as it was thought to be. Taxonomy Mootnick and Groves stated that hoolock gibbons do not belong in the genus ''Bunopithecus'', and placed them in a new genus, ''Hoolock''. This genus was argued to contain two distinct species which were previously thought to be subspecies: ''Hoolock hoolock'' and ''Hoolock leuconedys''. The ranges of the two species are unclear and may overlap, and intermediates may occur. Habitat and ecology The eastern hoolock gibbon is a forest-dwelling primate that prefers a continuous canopy, which makes them vulnerable to loss of habitat. They can be foun ...

Species Endangered By The Pet Trade
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes in zoological ...

Endangered Fauna Of Asia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of India
This list of mammals of India comprises all the mammal species alive in India today. Some of them are common to the point of being considered vermin while others are exceedingly rare. Many species are known from just a few zoological specimens in museums collected in the 19th and 20th centuries. Many of the carnivores and larger mammals are restricted in their distribution to forests in protected areas, while others live within cities in the close proximity of humans. They range in size from the Eurasian pygmy shrew (''Sorex minutus'') to the Asian elephant (''Elephas maximus''). They include nocturnal small mammals endemic to India such as the Malabar large-spotted civet (''Viverra civettina''). While the status of many of these species is unknown, some are definitely extinct. Populations of many carnivores are threatened. The tiger (''Panthera tigris''), dhole (''Cuon alpinus''), and Malabar large-spotted civet (''Viverra civettina'') are some of the most endangered carnivore sp ...

Mammals Of Myanmar
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 with Sauropsida ...

Primates Of South 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 ...

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] |
Forest Degradation
Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition. "The forest is still there, but with fewer trees, or less species of trees, plants or animals, or some of them affected by plagues. This degradation makes the forest less valuable and may lead to deforestation. Forest degradation is a type of the more general issue of land degradation. Deforestation and forest degradation continue to take place at alarming rates, which contributes significantly to the ongoing loss of biodiversity. Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoolock Gibbon Mizoram
The hoolock gibbons are three primate species of genus ''Hoolock'' in the gibbon family, Hylobatidae, native to eastern Bangladesh, Northeast India, Myanmar, and Southwest China. Description Hoolocks are the second-largest of the gibbons, after the siamang. They reach a size of 60 to 90 cm and weigh 6 to 9 kg. The sexes are about the same size, but they differ considerably in coloration; males are black-colored with remarkable white brows, while females have a grey-brown fur, which is darker at the chest and neck. White rings around their eyes and mouths give their faces a mask-like appearance. The ''Oxford English Dictionary'' says that the name "hoolock" is from "a language of Assam." Distribution In northeast India, the hoolock is found south of Brahmaputra and the North Bank areas and east of the Dibang Rivers. Its range extends into seven states covering Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura (The seven northeastern states of ...
