Bubalus bubalis arnee | |
Буйвол дикой воды ( Bubalus arnee ), также называемый азиатским буйволом , азиатским буйволом и диким буйволом , является крупным крупным крупным током на индийском субконтиненте и Юго -Восточной Азии. С 1986 года он был указан как находящийся под угрозой исчезновения в Красном списке МСОП , поскольку оставшаяся популяция составляет менее 4000. Снижение населения не менее 50% за последние три поколения (24–30 лет) [ когда? ] прогнозируется, что продолжится. Население глобального населения было оценено в 3400 человек, из которых 95% живут в Индии, в основном в Ассаме . Буффало дикой воды является наиболее вероятным предком домашнего водного буйвола .
Таксономия
[ редактировать ]
Бос Арни был научным названием, предложенным Робертом Керром в 1792 году, который описал череп с рогами зоологического образца Буффало из Бенгалии в северной Индии. [ 3 ] Конкретное название Arnee получено из хинди -арни , которое упоминалось о самок буйволах с дикой водой; Термин связан с санскритом Арана («лес») и Араной («Странно, иностранец». [4][5] Bubalus arnee was proposed by Charles Hamilton Smith in 1827 who introduced the generic name Bubalus for bovids with large heads, convex-shaped narrow foreheads, laterally bent flat horns, funnel-shaped ears, small dewlaps and slender tails.[6] Later authors subordinated the wild water buffalo under either Bos, Bubalus or Buffelus.[7]
In 2003, the International Commission on Zoological Nomenclature placed Bubalus arnee on the Official List of Specific Names in Zoology, recognizing the validity of this name for a wild species.[8] Most authors have adopted the binomen Bubalus arnee for the wild water buffalo as valid for the taxon.[9]
The wild water buffalo is the most likely ancestor of the domestic water buffalo.[10][11]
Only a few DNA sequences are available from wild water buffalo populations.[12] Wild populations are considered to be the progenitor of the modern domestic water buffalo, but the genetic variation within the species is unclear, and also how it is related to the domesticated river and Carabao swamp buffaloes.[13]
Characteristics
[edit]
The wild water buffalo has an ash-gray to black skin. The moderately long, coarse and sparse hair is directed forward from the haunches to the long and narrow head. There is a tuft on the forehead, and the ears are comparatively small. Its head-to-body-length is 240 to 300 cm (94 to 118 in) with a 60 to 100 cm (24 to 39 in) long tail and a shoulder height of 150 to 190 cm (59 to 75 in). Both sexes carry horns that are heavy at the base and widely spreading up to 2 m (6 ft 7 in) along the outer edges, exceeding in size the horns of any other living bovid. The tip of the tail is bushy; the hooves are large and splayed.[14] It is larger and heavier than the domestic water buffalo, and weighs from 600 to 1,200 kg (1,300 to 2,600 lb).[15][16] The average weight of three captive wild water buffaloes was 900 kg (2,000 lb).[17] It is among the heaviest living wild bovid species, and is slightly smaller than gaur.[18]
Distribution and habitat
[edit]
The wild water buffalo occurs in India, Nepal, Bhutan, Thailand, and Cambodia, with an unconfirmed population in Myanmar. It has been extirpated in Bangladesh, Laos, Vietnam, and Sri Lanka.[2][19] It is associated with wet grasslands, swamps, flood plains and densely vegetated river valleys.[2]
India hosts 95% of the total global wild buffalo population, with over 2,600 wild water buffaloes in Assam.[20] It is largely restricted to in and around Kaziranga, Manas and Dibru-Saikhowa National Parks, Laokhowa Wildlife Sanctuary and Bura Chapori Wildlife Sanctuary and in a few scattered pockets in Assam, and in and around D'Ering Memorial Wildlife Sanctuary in Arunachal Pradesh. A small population survives in Balphakram National Park in Meghalaya, and in Chhattisgarh in Indravati National Park and Udanti Wildlife Sanctuary.[19] This population might extend into adjacent parts of Odisha and Gadchiroli District of Maharashtra. In the early 1990s, there may still have been about 3,300–3,500 wild water buffaloes in Assam and the adjacent states of northeast India.[21] In 1997, the number was assessed at less than 1,500 mature individuals.[2]
Many surviving populations are thought to have interbred with feral or domestic water buffaloes. In the late 1980s, fewer than 100 wild water buffaloes were left in Madhya Pradesh.[22] By 1992, only 50 animals were estimated to have survived there.[21]
Nepal's only population lives in Koshi Tappu Wildlife Reserve and has grown from 63 individuals in 1976 to 219 individuals in 2009.[23] In 2016, 18 individuals were translocated from Koshi Tappu Wildlife Reserve to Chitwan National Park.[24]
In and around Bhutan's Royal Manas National Park, a small number of wild water buffaloes occur. This is part of the sub-population that occurs in India's Manas National Park.[19] In Myanmar, a few animals live in Hukaung Valley Wildlife Sanctuary.[2]
In Thailand, wild water buffaloes have been reported to occur in small herds of less than 40 individuals. A population of 25–60 individuals inhabited lowland areas of the Huai Kha Khaeng Wildlife Sanctuary between December 1999 and April 2001. This population has not grown significantly in 15 years, and is maybe interbreeding with domestic water buffaloes.[25]
The population in Cambodia is confined to a small area of easternmost Mondulkiri and possibly Ratanakiri Provinces. Only a few dozen individuals remain.[26]
The wild water buffaloes in Sri Lanka are thought to be descendants of the introduced domestic water buffalo. It is unlikely that any true wild water buffaloes remain there today.[2]
Wild-living populations found elsewhere in Asia, Australia, Argentina and Bolivia are feral domestic water buffaloes.[14]
Ecology and behavior
[edit]Wild water buffaloes are both diurnal and nocturnal. Adult females and their young form stable clans of as many as 30 individuals which have home ranges of 170 to 1,000 ha (420 to 2,470 acres), including areas for resting, grazing, wallowing, and drinking. Clans are led by old cows, even when bulls accompany the group. Several clans form a herd of 30 to 500 animals that gather at resting areas. Adult males form bachelor groups of up to 10 individuals, with older males often being solitary, and spend the dry season apart from the female clans. They are seasonal breeders in most of their range, typically in October and November. However, some populations breed year round. Dominant males mate with the females of a clan who subsequently drive them off. Their gestation period is 10 to 11 months, with an inter-birth interval of one year. They typically give birth to a single offspring, although twins are possible. Age at sexual maturity is 18 months for males, and three years for females. The maximum known lifespan is 25 years in the wild.[14] In the wild in Assam, the herd size varies from three to 30 individuals.[19]
They are probably grazers by preference, feeding mainly on graminoids when available, such as Bermuda grass, and Cyperus sedges, but they also eat other herbs, fruits, and bark, as well as browsing on trees and shrubs.[27] They also feed on crops, including rice, sugarcane, and jute, sometimes causing considerable damage.[28]
Tigers and mugger crocodiles prey on adult wild water buffaloes, and Asian black bears have also been known to kill them.[29]
Threats
[edit]A population reduction by at least 50% over the last three generations seems likely given the severity of the threats, especially hybridization; this population trend is projected to continue into the future. The most important threats are:[2]
- interbreeding with feral and domestic water buffaloes in and around protected areas;
- hunting, especially in Thailand, Cambodia, and Myanmar;
- habitat loss of floodplain areas due to conversion to agriculture and hydropower development;
- degradation of wetlands due to invasive species such as stem twiners and lianas;
- diseases and parasites transmitted by domestic livestock;
- interspecific competition for food and water between wild water buffaloes and livestock.
Conservation
[edit]Bubalus arnee is included in CITES Appendix III, and is legally protected in Bhutan, India, Nepal, and Thailand.[2]
In 2017, 15 wild water buffaloes were reintroduced into Chitwan National Park in Nepal to establish a second viable sub-population in the country.[30]
In 2023, 4 wild buffalos were translocated to Udanti-Sitanadi Tiger Reserve to reverse its declining population in the state.[31]
