Chital Deer
The chital or cheetal (''Axis axis''; ), also known as the spotted deer, chital deer, and axis deer, is a deer species native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach and females at the shoulder. While males weigh , females weigh around . It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly long. Etymology The vernacular name "chital" (pronounced ) comes from ''cītal'' ( hi, चीतल), derived from the Sanskrit word ' (चित्रल), meaning "variegated" or "spotted". The name of the cheetah has a similar origin. Variations of "chital" include "cheetal" and "cheetul". Other common names for the chita ...

Kanha National Park
Kanha Tiger Reserve, also known as Kanha–Kisli National Park, is one of the tiger reserves of India and the largest national park of the state of Madhya Pradesh. The present-day Kanha area is divided into two protected areas, Hallon and Banjar, of , respectively. Kanha National Park was created on 1 June 1955 and was designated a tiger reserve in 1973. Today, it encompasses an area of in the two districts Mandla and Balaghat. Together with a surrounding buffer zone of and the neighbouring Phen Sanctuary, it forms the Kanha Tiger Reserve, which is one of the biggest in the country. This makes it the largest national park in central India. The park hosts Bengal tiger, Indian leopard, sloth bear, barasingha and dhole. It is also the first tiger reserve in India to officially introduce a mascot, Bhoorsingh the Barasingha. Flora Kanha Tiger Reserve is home to over 1000 species of flowering plants. The lowland forest is a mixture of sal (''Shorea robusta'') and other mixed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Hamilton Smith
Lieutenant-Colonel Charles Hamilton Smith, KH, KW, FRS, FLS, (26 December 1776 in East Flanders, in the United Provinces of the Netherlands – 21 September 1859 in Plymouth) was an English artist, naturalist, antiquary, illustrator, soldier, and spy. Military service His military career began in 1787, when he studied at the Austrian academy for artillery and engineers at Mechelen and Leuven in Belgium. Although his military service, which ended in 1820 and included the Napoleonic Wars, had him travel extensively (including the West Indies, Canada, and United States), much of his time was spent at a desk job in Britain. One of his noteworthy achievements was an 1800 experiment to determine which colour should be used for military uniforms. The increasing accuracy of firearms, especially rifles, brought advantages to shades which offer a less distinctive target – by testing the accuracy of a rifle company against grey, green, and red targets, he showed scientifically the a ...

Rucervus
''Rucervus'' is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. The only extant representatives, the barasingha (''R. duvaucelii)'' and Eld's deer (''R. eldii''), are threatened by habitat loss and hunting, and another species ('' R. schomburgki)'' became extinct in 1938. The species of the genus ''Rucervus'' are characterized by a specific antler structure: its basal ramification is often supplemented with an additional small prong, the middle tine is never present, while the crown tines are inserted on the posterior side of the beam and may be bifurcated or fused into a small palmation.

Genetic Divergence
Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become Reproductive isolation, reproductively isolated for some period of time, as there isn’t genetic exchange anymore. In some cases, subpopulations living in ecologically distinct peripheral environments can exhibit genetic divergence from the remainder of a population, especially where the range of a population is very large (see parapatric speciation). The genetic differences among divergent populations can involve silent mutations (that have no effect on the phenotype) or give rise to significant Morphology (biology), morphological and/or physiology, physiological changes. Genetic divergence will always accompany reproductive isolation, either due to novel adaptations via selection and/or due to genetic drift, and is the principal ...

Schomburgk's Deer
The Schomburgk's deer (''Rucervus schomburgki'') is an extinct species of deer once endemic to central Thailand. It was described by Edward Blyth in 1863 and named after Sir Robert H. Schomburgk, who was the British consul in Bangkok from 1857 to 1864. It is thought to have gone extinct by 1938, when the last records of the species were published. Description This deer was a graceful species, similar in appearance to the related barasingha (''R. duvaucelii''). The pelt was a dark brown with lighter underparts. The underside of the tail was white. Males possessed basket-like antlers, upon which all the main tines branched. This caused the deer to have up to 33 points on their antlers and the outer edge of the rack to be up to long. Females had no antlers. Habitat Schomburgk's deer inhabited swampy plains with long grass, cane, and shrubs in central Thailand, particularly in the Chao Phraya River valley near Bangkok. This deer avoided dense vegetation. They lived in herds that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barasingha
The barasingha (''Rucervus duvaucelii''), also known as the swamp deer, is a deer species distributed in the Indian subcontinent. Populations in northern and central India are fragmented, and two isolated populations occur in southwestern Nepal. It has been extirpated in Pakistan and Bangladesh, and its presence is uncertain in Bhutan. The specific name commemorates the French naturalist Alfred Duvaucel. The swamp deer differs from all other Indian deer species in that the antlers carry more than three tines. Because of this distinctive character it is designated ''bārah-singgā'', meaning "twelve-horned" in Hindi.Lydekker, R. (1888–1890)''The new natural history'' Volume 2 Printed by order of the Trustees of the British Museum (Natural History), London. Mature stags usually have 10 to 14 tines, and some have been known to have up to 20.Prater, S. H. (1948). ''The book of Indian animals''. Oxford University Press. (10th ed.)

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rusa (genus)
''Rusa'' is a genus of deer from southern Asia. They have traditionally been included in ''Cervus'', and genetic evidence suggests this may be more appropriate than their present placement in a separate genus.Pitraa, Fickela, Meijaard, Groves (2004). ''Evolution and phylogeny of old world deer.'' Molecular Phylogenetics and Evolution 33: 880–895. Three of the four species have relatively small distributions in the Philippines and Indonesia, but the sambar is more widespread, ranging from India east and north to China and south to the Greater Sundas. All are threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species.

Hyelaphus
''Axis'' is a genus of deer occurring in South and Southeast Asia. As presently defined by most authorities, four species are placed in the genus. Three of the four species are called hog deer. The genus name is a word mentioned in Pliny the Elder's Natural History. Species Following the third edition of ''Mammal Species of the World'' from 2005, which is also followed by the American Society of Mammalogists The American Society of Mammalogists (ASM) was founded in 1919. Its primary purpose is to encourage the study of mammals, and professions studying them. There are over 4,500 members of this society, and they are primarily professional scientists ..., four species are placed in ''Axis''. These four species are divided into two subgenera; ''Axis'' containing the chital, and ''Hyelaphus'' containing the 3 others.
