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 springbok or springbuck is a medium-sized antelope found mainly in south and southwest Africa. The sole member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches 71 to 86 cm at the shoulder and weighs between 27 and 42 kg. Both sexes have a pair of black, 35-to-50 cm (14-to-20 in) long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light-brown coat marked by a reddish-brown stripe that runs from the upper fore leg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap.
The term antelope is used to refer to many species of even-toed ruminant that are indigenous to various regions in Africa and Eurasia.
The markhor is a large Capra species native to Central Asia, the Karakoram, 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 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 include the gazelles, blackbucks, springboks, gerenuks, dibatags, and Central Asian gazelles, are often referred to as true antelopes. 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 saigas and Tibetan antelopes inhabit much of central and western Asia. The dwarf antelopes of tribe Neotragini live entirely in sub-Saharan Africa.
The mountain gazelle, also called the True Gazelle or the Palestine Mountain Gazelle, is a species of gazelle widely but unevenly distributed.
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.
The Himalayan goral or the gray goral, is a bovid species native to the Himalayas. It is listed as Near Threatened on the IUCN Red List because the population is thought to be declining significantly due to habitat loss and hunting for meat.
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 of Ladakh in India. 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, as well as some parts of Siberia and China. The name dzeren is Russian misinterpretation of the Mongolian language name of zeer or 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.
Grant's gazelle is a relatively large species of gazelle antelope, distributed from northern Tanzania to South Sudan and Ethiopia, and from the Kenyan coast to Lake Victoria. Its Swahili name is swala granti. It was named for a 19th-century British explorer, James Grant.
The Asian ibex, also known using regionalized names as the Siberian ibex,Altai ibex, Central Asian ibex, Gobi ibex, Himalayan ibex, Mongolian ibex or Tian Shan ibex, is a polytypic species of ibex. It lives in central Asia, it is by far the most widely distributed species in the genus Capra and Asian ibex is listed as Near Threatened in view of the prevalence of threats, low densities in most areas and overall population decline, but available data are of insufficient reliability and area coverage. It has formerly been treated as a subspecies of the Alpine ibex, and whether it is a single species or a complex of distinct units that stand out as genetically differentiated at species level is still not entirely clear. It is the longest and heaviest member of the genus Capra, though its shoulder height is surpassed by the markhor.
A gazelle is one of many antelope species in the genus Gazella. This article also deals with the 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.
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.
Heuglin's gazelle, also known as the Eritrean gazelle, is a species of gazelle found east of the Nile River in Eritrea, Ethiopia and Sudan. It was considered a subspecies of the red-fronted gazelle or conspecific with Thomson's gazelle and Mongalla gazelle by some authors in the past. This small gazelle stands nearly 67 cm (26 in) at the shoulder and weighs between 15 and 35 kg. The coat is dark reddish brown with a dark reddish stripe on the flanks, except for the underparts and the rump which are white. Horns, present in both sexes, measure 15 to 35 cm in length.
