Douc
The doucs or douc langurs make up the genus ''Pygathrix''. They are colobine Old World monkeys, native to Southeast Asia, which consists of these 3 species: red-shanked douc, black-shanked douc, and gray-shanked douc. Description The doucs are colobine Old World monkeys, which make up the genus ''Pygathrix''. They are native to Southeast Asia. Classification The doucs make up the genus ''Pygathrix'', which consists of these 3 species: * Red-shanked douc, ''Pygathrix nemaeus'' * Black-shanked douc, ''Pygathrix nigripes'' * Gray-shanked douc, ''Pygathrix cinerea'' Even though they are known as "douc langurs", they are in fact more closely related to the proboscis monkey and snub-nosed monkeys than to any of the langurs. They are part of the subfamily Colobinae of the family Cercopithecidae Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae ().

Red-shanked Douc
The red-shanked douc (''Pygathrix nemaeus'') is an arboreal and diurnal Old World monkey belonging to the Colobinae subfamily. They are endemic to Laos, Vietnam and Cambodia. They are known for their bright colors and express exhibit sexual dimorphism through their body size. The species have been declared critically endangered by the International Union for Conservation of Nature, with the main threats being from hunting, habitat loss and pet trade. They are one of three species in the genus ''Pygathrix'', the other two being the black-shanked ('' P. nigripes'') and gray-shanked ('' P. cinerea'') doucs. Red-shanked doucs live in fission-fusion, multilevel societies that have a mean of 18 individuals per band. They are folivorous and consume mainly ''Acacia pruinescens, Ficus racemosa, Millettia nigrescens, Zanthoxylum avicennae'' and ''Castanopsis ceratacantha''. Their four-chambered stomachs that allow for bacterial fermentation help them with their high-fiber diet. Geograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black-shanked Douc
The black-shanked douc (''Pygathrix nigripes'') is an endangered species of douc found mostly in the forests of Eastern Cambodia, with some smaller populations in Southern Vietnam. The region they are mostly found in is called the Annamite Range, a mountainous area that passes through Cambodia and Vietnam. Its habitat is mostly characterized by evergreen forest in the mountains, in the middle to upper canopy. They move around quadrupedally and by brachiation up in the trees. This species is unique with its coloration among the doucs as it has a bluish face with yellow rings around its eyes a blue scrotum and a pink penis. Like other doucs, this specie has a tail as long as its body and head length. Black-shanked douc have been observed in groups ranging from 3 to 30 indivuals, depending on their habitat. Group tend to have a fission-fusion dynamic that changes with food availability. Their diet varies from dry to wet season. Regardless of the season, their diet consists mostly of le ...

Colobine
The Colobinae or leaf-eating monkeys are a subfamily of the Old World monkey family that includes 61 species in 11 genera, including the black-and-white colobus, the large-nosed proboscis monkey, and the gray langurs. Some classifications split the colobine monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera ''Colobus'', '' Piliocolobus'', and '' Procolobus'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of mtDNA confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups, while others place them firmly within the langur group.

Philadelphia Zoo
The Philadelphia Zoo, located in the Centennial District of Philadelphia on the west bank of the Schuylkill River, is the first true zoo in the United States. It was chartered by the Commonwealth of Pennsylvania on March 21, 1859, but its opening was delayed by the Civil War until July 1, 1874. The zoo opened with 1,000 animals and an admission price of 25 cents. For a brief time, the zoo also housed animals brought to U.S. from safaris by the Smithsonian Institution, which had not yet built its National Zoo. The Philadelphia Zoo is one of the premier zoos in the world for breeding animals that are difficult to breed in captivity. The zoo also works with many groups around the world to protect the natural habitats of the animals in their care. The zoo is and the home of nearly 1,300 animals, many of which are rare and endangered. Special features include a children's petting zoo, a paddleboat lake, a rainforest themed carousel, a ropes course, and many interactive and educati ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Old World Monkey
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus'') and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus ''Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, surili (''Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago. The smallest Old World monkey is the talapoin, with a head and body 34–37 cm in length, and weighing between 0.7 and 1.3 kg. The largest is the male mandrill, around 70 cm in length, and weighing up to 50 kg. Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
