The goa (Procapra picticaudata), also known as the Tibetan gazelle, is a species of antelope that inhabits the Tibetan plateau.
The goa is a relatively small antelope, with slender and graceful bodies. Both males and females stand 54 to 65 centimetres (21 to 26 in) tall at the shoulder, measure 91 to 105 cm (36 to 41 in) in head-body length and weigh 13 to 16 kg (29 to 35 lb). Males have long, tapering, ridged horns, reaching lengths of 26 to 32 cm (10 to 13 in). The horns are positioned close together on the forehead, and rise more or less vertically until they suddenly diverge towards the tips. Females have no horns, and neither sex has distinct facial markings. [2]
The goa is grayish brown over most of its body, with its summer coat being noticeably greyer in colour than its winter one. It has a short, black-tipped tail in the center of its heart-shaped white rump patches. Its fur lacks an undercoat, consisting of long guard hairs only, and is notably thicker in winter. It appears to have excellent senses, including keen eyesight and hearing. [2] Its thin and long legs enhance its running skills, which are required to escape from predators.
The goa is native to the Tibetan plateau, and is widespread throughout the region, inhabiting terrain between 3,000 and 5,750 m (9,840 and 18,860 ft) in elevation. It is almost restricted to the Chinese provinces of Gansu, Xinjiang, Tibet, Qinghai, and Sichuan, with tiny populations in the Ladakh and Sikkim regions of India. No distinct subspecies of goa have been reported. [2]
Alpine meadow and high elevation steppe are the primary habitats of the goa. It is scattered widely across its range, being present in numerous small herds spread wide apart; estimates of population density vary from 2.8 individuals per sq km to less than 0.1, depending on the local environment. [2]
Unlike some other ungulates, goas do not form large herds, and are typically found in small family groups. Although they occasionally gather into larger aggregations, most goa groups contain no more than 10 individuals, and many are solitary. They have been noted to give short cries and calls to alert the herd on approach of a predator or other perceived threat. [2]
Goas feed on a range of local vegetation, primarily forbs and legumes, supplemented by relatively small amounts of grasses and sedges. Their main local predators are the Himalayan wolf [3] and the snow leopard. [4]
For much of the year, the sexes remain separate, with the females grazing in higher altitude terrain than the males. The females descend from their high pastures around September, prior to the mating season in December. During the rut, the males are largely solitary, scent marking their territories and sometimes butting or wrestling rival males with their horns.
Gestation lasts around six months, with the single young being born between July and August. The infants remain hidden with their mother for the first two weeks of life, before rejoining the herd. The age of sexual maturity in goas is unknown, but is probably around 18 months. Goas have lived for up to five years and seven months in captivity. [2]
Although goa populations have declined over recent years, they do not inhabit regions of high human population over most of their range, and do not significantly compete with local livestock. Because of their small size, they are not popular targets for hunting, and they are classified as a class II protected species in China. The primary threats to the goa in China are loss of habitat, due to encroachment on their natural ranges by pastoralists and the expansion of agriculture in the western provinces. [2]
In Ladakh, they live at high altitudes (4,750-5,050 m or 15,580-16,570 ft), but prefer relatively flat areas with an affinity for warmer, south-facing slopes. They coexist with domestic yaks and kiang, but are competitive with domestic goats and sheep and avoid herders and their dogs. [5] The population in Ladakh, less than 100 individuals, continues to decline. Within Ladakh, its distribution was spread as far west as the Tsokar Basin in the beginning of the 20th century, but today is confined to the Hanle Valley and the neighbouring areas, such as Chumur. Presently gazelles are suffering not only from poor pasture conditions, but also from problems associated with small populations such as lack of genetic diversity in the population, which makes them less resistant to diseases. [6]
Goa populations in both Ladakh and Tibet seem to be declining precipitously and are threatened with extinction, at least in some regions. [6] [7] A small population also exists in northern Sikkim, right at the border between India and Chinese-controlled territories, apparently moving back and forth between the countries.[ citation needed ]
The term antelope refers to numerous extant or recently extinct species of the ruminant artiodactyl family Bovidae that are indigenous to most of Africa, India, the Middle East, Central Asia, and a small area of Eastern Europe. Antelopes do not form a monophyletic group, as some antelopes are more closely related to other bovid groups, like bovines, goats, and sheep, than to other antelopes.
Ladakh is a region administered by India as a union territory and constitutes an eastern portion of the larger Kashmir region that has been the subject of a dispute between India and Pakistan since 1947 and India and China since 1959. Ladakh is bordered by the Tibet Autonomous Region to the east, the Indian state of Himachal Pradesh to the south, both the Indian-administered union territory of Jammu and Kashmir and the Pakistan-administered Gilgit-Baltistan to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south. The eastern end, consisting of the uninhabited Aksai Chin plains, is claimed by the Indian Government as part of Ladakh, but has been under Chinese control.
The markhor is a large wild Capra (goat) species native to South Asia and Central Asia, mainly within Pakistan, India, the Karakoram range, parts of Afghanistan, and the Himalayas. It is listed on the IUCN Red List as Near Threatened since 2015.
The Tibetan antelope or chiru is a medium-sized bovid native to the northeastern Tibetan plateau. Most of the population live within the Chinese border, while some scatter across India and Bhutan in the high altitude plains, hill plateau and montane valley. Fewer than 150,000 mature individuals are left in the wild, but the population is currently thought to be increasing. In 1980s and 1990s, they had become endangered due to massive illegal poaching. They are hunted for their extremely soft, light and warm underfur which is usually obtained after death. This underfur, known as shahtoosh, is used to weave luxury shawls. Shahtoosh shawls were traditionally given as wedding gifts in India and it takes the underfur of three to five adult antelopes to make one shawl. Despite strict controls on trade of shahtoosh products and CITES listing, there is still demand for these luxury items. Within India, shawls are worth $1,000–$5,000; internationally the price can reach as high as $20,000. In 1997 the Chinese government established the Hoh Xil National Nature Reserve solely to protect the Tibetan antelope population.
The blackbuck, also known as the Indian antelope, is a medium-sized antelope native to India and Nepal. It inhabits grassy plains and lightly forested areas with perennial water sources. It stands up to 74 to 84 cm high at the shoulder. Males weigh 20–57 kg (44–126 lb), with an average of 38 kg (84 lb). Females are lighter, weighing 20–33 kg (44–73 lb) or 27 kg (60 lb) on average. Males have 35–75 cm (14–30 in) long corkscrew horns, and females occasionally develop horns, as well. The white fur on the chin and around the eyes is in sharp contrast with the black stripes on the face. Both sexes' coats feature a two-tone colouration; in males, the majority of the body is dark brown to black, with white circles around the eyes, white ears and tail, and the belly, lower jaw, and inner legs also white. Females and juveniles are yellowish-fawn to tan and display the same white areas, only with more of a beige tone than the males. Females also feature a more pronounced horizontal white side-stripe, starting around the shoulder and ending at the rump. The blackbuck is the sole living member of the genus Antilope and was described by Carl Linnaeus in 1758. Two subspecies are recognized.
The bharal, also called the blue sheep, is a caprine native to the high Himalayas. It is the only member of the genus Pseudois. It occurs in India, Bhutan, China, Myanmar, Nepal, and Pakistan. The Helan Mountains of Ningxia have the highest concentration of bharal in the world, with 15 bharals per km2 and 30,000 in total.
The antilopines are even-toed ungulates belonging to the subfamily Antilopinae of the family Bovidae. The members of tribe Antilopini are often referred to as true antelopes, and include the gazelles, blackbucks, springboks, gerenuks, dibatags, and Central Asian gazelles. True antelopes occur in much of Africa and Asia, with the highest concentration of species occurring in East Africa in Sudan, Eritrea, Ethiopia, Somalia, Kenya, and Tanzania. The saiga inhabits Central and Western Asia, mostly in regions from the Tibetan Plateau and north of the Indian Subcontinent. The dwarf antelope species of tribe Neotragini live entirely in sub-Saharan Africa.
Thomson's gazelle is one of the best known species of gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus Gazella within the subgenus Eudorcas, before Eudorcas was elevated to genus status.
The argali, also known as the mountain sheep, is a wild sheep that roams the highlands of western East Asia, the Himalayas, Tibet, and the Altai Mountains.
Hemis National Park is a high-elevation national park in Hemis in Leh district of Ladakh, India. It approx. 50 km from Leh, the capital of Ladakh. Globally famous for its snow leopards, it is believed to have the highest density of them in any protected area in the world. It is the only national park in India that is north of the Himalayas, the largest notified protected area in India and is the second largest contiguous protected area, after the Nanda Devi Biosphere Reserve and surrounding protected areas. The park is home to a number of species of endangered mammals, including the snow leopard. Hemis National Park is India's protected area inside the Palearctic realm, outside the Changthang Wildlife Sanctuary northeast of Hemis, and the proposed Tso Lhamo Cold Desert Conservation Area in North Sikkim.
Ladakh is the home to endemic Himalayan wildlife, such as the bharal, yak, Himalayan brown bear, Himalayan wolf and the iconic snow leopard. Hemis National Park, Changthang Cold Desert Wildlife Sanctuary, and Karakorum Wildlife Sanctuary are protected wildlife areas of Ladakh. The Mountain Institute, the Ladakh Ecological Development Group and the Snow Leopard Conservancy work on ecotourism in rural Ladakh. For such an elevated, arid area, Ladakh has great diversity of birds — 318 species have been recorded. Many of these birds reside at or seasonally breed in high-altitude wetlands, such as Tso Moriri, or near rivers and water sources.
The Changtang is a part of the high altitude Tibetan Plateau in western and northern Tibet extending into the southern edges of Xinjiang as well as southeastern Ladakh, India, with vast highlands and giant lakes. From eastern Ladakh, the Changtang stretches approximately 1,600 kilometres (990 mi) east into Tibet as far as modern Qinghai. The Changtang is home to the Changpa, a nomadic Tibetan people. The two largest settlements within the Tibetan Changtang are Rutog Town the seat of Rutog County and Domar Township the seat of Shuanghu County.
Tso Moriri or Lake Moriri or "Mountain Lake", is a lake in the Changthang Plateau in Leh district of the union territory of Ladakh in India. It is located approx. 219 km from Leh City, capital of Ladakh. The lake and surrounding area are protected as the Tso Moriri Wetland Conservation Reserve.
The Mongolian gazelle, or dzeren, is a medium-sized antelope native to the semiarid Central Asian steppes of Mongolia, southern Siberia and northern China. The name dzeren is the Russian spelling and pronunciation of the Mongolian word zeer, or the Buryat zeeren.
Przewalski's gazelle is a member of the family Bovidae, and in the wild, is found only in China. Once widespread, its range has declined to six populations near Qinghai Lake. The gazelle was named after Nikolai Przhevalsky, a Russian explorer who collected a specimen and brought it back to St. Petersburg in 1875.
The Himalayan wolf is a canine of debated taxonomy. It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic grey wolf, genetically the same wolf as the Tibetan and Mongolian wolf, and has an association with the African wolf. No striking morphological differences are seen between the wolves from the Himalayas and those from Tibet. The Himalayan wolf lineage can be found living in Ladakh in the Himalayas, the Tibetan Plateau, and the mountains of Central Asia predominantly above 4,000 m (13,000 ft) in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations.
The Siberian ibex, also known using regionalized names including Altai ibex,Asian ibex, Central Asian ibex, Gobi ibex, Himalayan ibex, Mongolian ibex or Tian Shan ibex, is a polytypic species of ibex, a wild relative of goats and sheep. It lives in Central Asia, and is, by far, the most widely-distributed species in the genus Capra. In terms of population stability, Siberian ibex are currently ranked as Near Threatened, mostly due to over-hunting, low densities and overall decline; still, reliable data is minimal and difficult to come by, in addition to the animals’ expansive natural range, so accurate observations are still scant. The Siberian ibex has, formerly, been treated as a subspecies of the Eurasian Alpine ibex, and whether or not it is a single species or a complex of distinct units that stand out as genetically-distinct is still not entirely clear. The Siberian ibex is the longest and heaviest member of the genus Capra, though its shoulder height is slightly surpassed by the markhor.
A gazelle is one of many antelope species in the genus Gazella. There are also seven species included in two further genera; Eudorcas and Nanger, which were formerly considered subgenera of Gazella. A third former subgenus, Procapra, includes three living species of Asian gazelles.
Chang Tang National Nature Reserve lies in the northern Tibetan Plateau. It is the third-largest land nature reserve in the world, after the Northeast Greenland National Park and Kavango-Zambezi Transfrontier Conservation Area, with an area of over 334,000 km2 (129,000 sq mi), making it bigger than 183 countries. Administratively, it lies in Xainza County and Biru County of the Nagqu Prefecture. With the more recently established adjoining reserves listed below there is now a total of 496,000 km2 of connected Nature Reserves, which represents an area almost as large as Spain and bigger than 197 other countries.
Bovidae in Chinese mythology include various myths and legends about a group of biologically distinct animals which form important motifs within Chinese mythology. There are many myths about the animals modernly classified as Bovidae, referring to oxen, sheep, goats, and mythological types such as "unicorns". Chinese mythology refers to those myths found in the historical geographic area of China, a geographic area which has evolved or changed somewhat through history. Thus this includes myths in Chinese and other languages, as transmitted by Han Chinese as well as other ethnic groups. There are various motifs of animals of the Bovidae biological family in Chinese mythology. These have often served as allusions in poetry and other literature. Some species are also used in the traditional Chinese calendar and time-keeping system.
