The Gobi bear (Ursus arctos gobiensis), known in Mongolian as the Mazaalai ( Мазаалай ), is a subspecies of the brown deport (Ursus arctos) that is found in the Gobi Desert of Mongolia. Information technology is listed as critically endangered past the Mongolian Redbook of Endangered Species and by IUCN standards. [1] Based on a long-term DNA population demographic study, the population are existing with less than 40 adults in 2017, [ii] [three] and is separated by enough distance from other dark-brown bear populations to attain reproductive isolation. In 1959, hunting of the brute was prohibited in order to preserve the dying subspecies. [4]
Behaviour and ecology [ edit ]
Gobi bears mainly eat roots, berries, and other plants, sometimes rodents; there is no evidence that they prey on large mammals. Pocket-size compared to other brown bear subspecies, adult males weigh about 96.0–138.0 kg (211.6–304.2 lb) and females about 51.0–78.0 kg (112.4–172.0 lb). [4] Gobi bears are the only bears that accept evolved and adjusted to living in such extreme hot desert climates. [3]
Genetic multifariousness [ edit ]
Gobi bears accept a very depression genetic diversity, [2] [5] among the lowest ever observed in any subspecies of chocolate-brown bear. Levels of genetic diversity similar to the Gobi bears have been reported only in a pocket-sized population of chocolate-brown bears in the Pyrenees Mountains on the border of Kingdom of spain and France. The low genetic diversity is the result of Gobi Bears having a highly skewed sex ratio of males to females. There are well-nigh 21 males to 8 females. This the main cause of such low reproduction and population. In add-on, inquiry has shown there is a low number of alleles per locus in their Deoxyribonucleic acid. This means that Gobi Bear Deoxyribonucleic acid is fragile and therefore affects their reproduction. [3]
Research [ edit ]
Based on morphology, the Gobi brown bear has sometimes historically been classified as being of the same subspecies as the Tibetan blue acquit. However, recent phylogenetic assay has shown the Gobi behave and Himalayan brown conduct [six] take a shared ancestry and both these populations are currently genetically isolated. [5] There are fewer than 40 Gobi bears left in the wild. The Gobi bears used to populate about 23,619 kilometers of land in Southwestern Mongolia. This number has decreased past nearly sixty percentage due to the scarcity of nutrient and water among the large creatures who feast on plants, fruits, and lizards. Climate change and mining are the ii main threats to gobi bears and their extinction. If deserts start to get hotter and drier, information technology will make information technology difficult for the bears to find resources such as water and food. Mining is also simply equally important as it is causing damage to their environments. Some researchers have started to take investigations and they suggested that there are a few gobi bears left, as little equally 25. The rough desert natural surroundings may make this species connected being unstable. Gobi Bears will be more probable found in the Northern hemisphere, where their population is constitute to be healthier than the southern hemisphere due to a weaker conservation status. Gobi Bears are considered severely endangered as they are institute to be isolated. [2]
