It is the state animal of Tamil Nadu.Prater, S. H. 1948, 1971. ''The book of Indian Animals'', Bombay Natural History Society and Oxford University Press, India. 324 pages. . Despite its local name, it is more closely related to the sheep of the genus ''Ovis'' than the ibex and wild goats of the genus ''Capra''. It is the only species in the genus ''Nilgiritragus''. Etymology In Tamil, the Nilgiri tahr is called வரையாடு (''varaiaadu''). The word ''varaiaadu'' is derived from the Tamil words ''wurrai'' meaning "precipice" and ''aadu'' meaning "goat". The word in ancient Tamil was வருடை (''varudai''). In Malayalam, the word is വരയാട് (''varyaadu''). The Nilgiri tahr was described as ''Capra warryato'' by Gray. The genus name ''Ni ...

Montane Grassland
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline. This biome includes high elevation (montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the And ...

Arabian Tahr
The Arabian tahr (''Arabitragus jayakari'') is a species of tahr native to eastern Arabia. Until recently, it was placed in the genus '' Hemitragus'', but genetic evidence supports its removal to a separate monotypic genus, ''Arabitragus''. The Arabian tahr is the smallest species of tahr. The animal is of stocky build with backward-arching horns in both sexes. Males are much more robust than females. Their coats consist of a long, reddish-brown hair, with a dark stripe running down the back. Males possess the most impressive manes which extend right down the back and grow longer, based on the age. In the oldest males the muzzle darkens to black and the eye stripes also darken. As with most mountain goats and sheep, they have rubber-like hooves to provide balance and traction on the steep, rocky slopes. Habitat and range The Arabian tahr lives on steep rocky slopes of Al Hajar Mountains in Oman and the United Arab Emirates, at altitudes up to above sea level. It is also foun ...

Himalayan Tahr
The Himalayan tahr (''Hemitragus jemlahicus'') is a large even-toed ungulate native to the Himalayas in southern Tibet, northern India, western Bhutan and Nepal. It is listed as Near Threatened on the IUCN Red List, as the population is declining due to hunting and habitat loss. A recent phylogenetic analysis indicates that the genus ''Hemitragus'' is monospecific, and that the Himalayan tahr is a wild goat. The Himalayan tahr has been introduced to Argentina, New Zealand, South Africa and the United States. Taxonomy Tahr belong to the subfamily Caprinae in the order Artiodactyla. Their closest relatives in the subfamily Caprinae are sheep and goats. A subspecies, the Eastern Himalayan tahr or shapi, was described in 1944. This classification is not considered valid anymore, and no subspecies are currently recognized. Etymology The word "tahr," first used in English writings in 1835, is derived from the animal's local name in the Western Himalayas, which has otherwise be ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
