Eastern Black Crested Gibbon
The eastern black-crested gibbon (''Nomascus nasutus''), also known as the Cao-vit black crested gibbon or the Cao-vit crested gibbon, is a species of gibbon Gibbons () are apes in the family Hylobatidae (). The family historically contained one genus, but now is split into four extant genera and 20 species. Gibbons live in subtropical and tropical rainforest from eastern Bangladesh to Northeast India ... from southeast China and northern Vietnam. The term "Cao-vit" originated from the sounds of their calls or songs that villagers of Ngoc Khe, Phong Nam and Ngoc Con communes of Trung Khanh District, Cao Bang Province of Vietnam use to name for them. This name was officially used by gibbon experts since the rediscovery. From the 1960s until the 2000s there had been no confirmed sightings of the eastern black-crested gibbon and it was thought to be possibly extinct. In 2002 a small population was rediscovered by two Fauna and Flora International, FFI biologists in a karst forest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippe Alexandre Jules Künckel D'Herculais
Philippe Alexandre Jules Künckel d'Herculais (10 February 1843 Paris – 22 December 1918 Conflans-sur-Oise) was a French entomologist and zoologist. He was the nephew of the French chemist Théophile-Jules Pelouze (1807–1867) and the son of a doctor. He lost his father when he was two years old. After his baccalauré in 1860, he entered École nationale supérieure des mines de Paris, École des mines in 1861. He preferred, in 1864, to follow less theoretical courses at Collège de France, at Muséum national d'histoire naturelle and at the University of Paris, Sorbonne. He then met Émile Blanchard (1819–1900) becoming his pupil and private secretary. In 1866, he published his first mémoire which was on the anatomy of Hemiptera. In 1869, he entered the Muséum national d'histoire naturelle where he aided Émile Blanchard. He replaced Alphonse Milne-Edwards (1835–1900) who became assistant to his father Henri Milne-Edwards (1800–1885). He became one of the first teachers ...

Species Endangered By Deforestation
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 ...

Mammals Described In 1884
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 Saurops ...

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 ...

Nomascus
''Nomascus'' is the second-most speciose genus of gibbons (family Hylobatidae). Originally, this genus was a subgenus of ''Hylobates'', and all individuals were considered one species, ''Hylobates concolor''. Species within ''Nomascus'' are characterized by 52 chromosomes. Some species are all black, some are light with a distinct black tuft of crown fur, and some have distinct, light-colored cheek patches. ''Nomascus'' is found from southern China (Yunnan) to southern Vietnam, and also on Hainan Island. One species, ''Nomascus nasutus,'' has been deemed "the most critically endangered ape species in the world". All species in this genus are either endangered or critically endangered.

Cytochrome B
Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Function In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III () — also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is an analogous protein, cytochrome b6, a component of the plastoquinone-plastocyanin reductase (), also known as the b6f complex. These complexes are involved in electron transport, the pumping of protons to create a proton-motive force ( PMF). This proton gradient is used for the generation of ATP. These complexes play a vital role in cells. Structure Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. ...

Hainan Black Crested Gibbon
The Hainan black-crested gibbon or Hainan gibbon (''Nomascus hainanus''), is a Critically Endangered species of gibbon found only on Hainan Island, China. It was formerly considered a subspecies of the eastern black crested gibbon (''Nomascus nasutus'') from Hòa Bình and Cao Bằng provinces of Vietnam and Jingxi County in Guangxi Zhuang Autonomous Region, China. Molecular data, together with morphology and call differences, suggest it is a separate species. Its habitat consists of broad-leaved forests and semi-deciduous monsoon forests. It feeds on ripe, sugar-rich fruit, such as figs and, at times, leaves, and insects. Current status Hainan black-crested gibbons are under grave threat of extinction. They are currently identified as critically endangered on the International Union for Conservation of Nature’s Red List. Historically, they were widespread in China: Government records dating back to the 17th century state that their range used to cover half of China, altho ...
