Kashmir Gray Langur
The Kashmir gray langur (''Semnopithecus ajax'') is an Old World monkey, one of the langur species. It is a leaf-eating monkey. It has been reported from Jammu and Kashmir and Himachal Pradesh in northwestern India but evidence indicates it only occurs in the Chamba Valley in Himachal Pradesh. Because of its restricted range, fragmented population and threats from human agriculture and development activities it is listed as Endangered in the IUCN Red List. In Pakistan it occurs in Machiara National Park. It was formerly considered a subspecies of '' Semnopithecus entellus'' and is one of several ''Semnopithecus'' species named after characters from '' The Iliad'', along with '' Semnopithecus hector'' and '' Semnopithecus priam''. Ecology and behaviour It is arboreal and diurnal, and lives in temperate and alpine forests. It lives at the highest elevation of any non-human primate in the world and is found in forests at elevations ranging from . The birthing season for t ...

Semnopithecus
''Semnopithecus'' is a genus of Old World monkeys native to the Indian subcontinent, with all species with the exception of two being commonly known as gray langurs. Traditionally only the species ''Semnopithecus entellus'' was recognized, but since about 2001 additional species have been recognized. The taxonomy has been in flux, but currently eight species are recognized. Members of the genus ''Semnopithecus'' are Terrestrial animal, terrestrial, inhabiting forest, open lightly wooded habitats, and urban areas on the Indian subcontinent. Most species are found at low to moderate altitudes, but the Nepal gray langur and Kashmir gray langur occur up to in the Himalayas. Characteristics These langurs are largely gray (some more yellowish), with a black face and ears. Externally, the various species mainly differ in the darkness of the hands and feet, the overall color and the presence or absence of a crest. Typically all north Indian gray langurs have their tail tips looping tow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reginald Innes Pocock
Reginald Innes Pocock, (4 March 1863 – 9 August 1947) was a British zoologist. Pocock was born in Clifton, Bristol, the fourth son of Rev. Nicholas Pocock and Edith Prichard. He began showing interest in natural history at St. Edward's School, Oxford. He received tutoring in zoology from Sir Edward Poulton, and was allowed to explore comparative anatomy at the Oxford Museum. He studied biology and geology at University College, Bristol, under Conwy Lloyd Morgan and William Johnson Sollas. In 1885, he became an assistant at the Natural History Museum, and worked in the section of entomology for a year. He was put in charge of the collections of Arachnida and Myriapoda. He was also given the task to arrange the British birds collections, in the course of which he developed a lasting interest in ornithology. The 200 papers he published in his 18 years at the museum soon brought him recognition as an authority on Arachnida and Myriapoda; he described between 300 a ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, invasive species, and climate change. 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 consider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Pakistan
A mammal () is a vertebrate animal of the 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 middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 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, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes ... [...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 spe ...

Fauna Of The Himalayas
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a boo ...

Copulation (zoology)
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many aquatic animals use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates (such as all reptiles, some fish, and most birds) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while most mammals copulate vaginally, and many basal vertebrates reproduce sexually with external fertilization. In spiders and insects Spiders are often confused with insects, but they are not insects; instead, they are arachnids. Spiders have separate male and female sexes. Before mating and copulation, the male spider spins a small web and ejaculates on to it. He then stores the sperm in reservoirs on his large pedipalps, from which he tran ...

Infanticide (zoology)
In animals, infanticide involves the intentional killing of young offspring by a mature animal of the same species. Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates ( primate infanticide) but including microscopic rotifers, insects, fish, amphibians, birds and mammals. Infanticide can be practiced by both males and females. Infanticide caused by sexual conflict has the general theme of the killer (often male) becoming the new sexual partner of the victim's parent, which would otherwise be unavailable. This represents a gain in fitness by the killer, and a loss in fitness by the parents of the offspring killed. This is a type of evolutionary struggle between the two sexes, in which the victim sex may have counter-adaptations that reduce the success of this practice. It may also occur for other reasons, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloparental Care
Alloparenting (or alloparental care) is a term for any form of parental care provided by an individual towards young that are not its own direct offspring. These are often called "non-descendant" young, even though grandchildren can be among them. Among humans, alloparenting is often performed by a child's grandparents and older siblings. Individuals providing this care are called by the neutral term "alloparent" (or "helper"). Alloparental care encapsulates a diverse range of parenting systems across a range of animal groups and social structures. The alloparent–young relationship can be mutualistic or parasitic, and between or within species. Cooperative breeding, joint brood care, reciprocal allonursing, brood parasitism and cuckoldry represent situations in which alloparenting plays a role. This form of parenting is often seen among humans. However, it is not as popular among other species. Alloparenting is rare among classes of animals such as birds and mammals, with only ...

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.
