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. The Himalayan tahr has been introduced to Argentina, New Zealand, South Africa and the United States. Taxonomy and phylogeny 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. A recent phylogenetic analysis indicates that the genus ''Hemitragus'' is monospecific, and that the Himalayan tahr is a wild goat. Etymology The word "tahr," first used in English writings in 1835, is derived from the animal's local name in the Western Himalayas, which ...

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''. Description It is the smallest species of tahr. It 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 goat-antelopes, they have rubber-like hooves to provide balance and traction on the steep, rocky slopes. As of a 2018, the wild population is thought to comprise around 2,200 individuals. Habitat and range The Arabian tahr lives on steep rocky slopes of the Hajar Mountains in Oman and the United ...

Nilgiri Tahr
The Nilgiri tahr (''Nilgiritragus hylocrius'') is an ungulate that is endemic to the Nilgiri Hills and the southern portion of the Western and Eastern Ghats in the states of Tamil Nadu and Kerala in southern India. It is the only species in the genus ''Nilgiritragus'' and is closely related to the sheep of the genus ''Ovis''. It is the state animal of Tamil Nadu. Etymology The genus name ''Nilgiritragus'' is derived from the Sanskrit words Nila(blue) and Giri(mountains) meaning "blue hills" and the Greek word '' trágos'' meaning "goat". Taxonomy The Nilgiri tahr was described as ''Capra warryato'' by Gray. Taxonomy The species was formerly placed in the genus ''Hemitragus'' together with the Himalayan tahr (''H. jemlahicus'') and the Arabian tahr (''Arabitragus jayakari''). A 2005 phylogenetic analysis showed that the Himalayan and Arabian tahr are sisters of the genus '' Capra'' while the Nilgiri tahr is a sister of the genus ''Ovis'' and it was therefore separated i ...

Hemitragus Bonali
''Hemitragus bonali'', the Bonal tahr, is an extinct species of bovid from the Pleistocene of Europe and the Caucasus Mountains region. The most recent remains of the Bonal tahr were found in layers dating from 298,000 ± 55,000 ka. The Bonal tahr was closely related (and possibly ancestral to) another extinct European tahr species, ''Hemitragus cedrensis ''Hemitragus cedrensis'' is an extinct species of bovid known from the Eemian of France and the Iberian Peninsula.

Mammal Genera
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being '' Handbook of the Mammals of the World'' series and '' Mammal Species of the World''.

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brian Houghton Hodgson
Brian Houghton Hodgson (1 February 1801 – 23 May 1894) was a pioneer natural history, naturalist and ethnologist working in India and Nepal where he was a British Resident (title), Resident. He described numerous species of birds and mammals from the Himalayas, and several birds were named after him by others such as Edward Blyth. He was a scholar of Newar Buddhism and wrote extensively on a range of topics relating to linguistics and religion. He was an opponent of the British proposal to introduce English as the official medium of instruction in Indian schools. Early life Hodgson was the second of seven children of Brian Hodgson (1766–1858) and his wife Catherine (1776–1851), and was born at Lower Beech, Prestbury, Cheshire. His father lost money in a bad bank investment and had to sell their home at Lower Beech. A great-aunt married to Beilby Porteus, the Bishop of London, helped them but the financial difficulties were great. Hodgson's father worked as a warden of the M ...

Bovids
The Bovidae comprise the family (biology), biological family of cloven-hoofed, ruminant mammals that includes Bos, cattle, bison, Bubalina, buffalo, antelopes (including Caprinae, goat-antelopes), Ovis, sheep and Capra (genus), goats. A member of this family is called a bovid. With 143 Extant taxon, extant species and 300 known Extinction, extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and Fur, pelage colouration. Except some Polled livestock, domesticated forms, all male bovids have two or more horn (anatomy), horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal Genera With One Living Species
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 the lar ...
