TIBETAN BLUE BEAR animalia.bio/tibetan-blue-bear The Tibetan bear or Tibetan blue bear is a subspecies of the brown bear found in the eastern Tibetan Plateau. It is also known as the Himalayan blue bear, Himalayan snow bear, Tibetan brown bear, or the horse bear. In Tibetan, it is known as Dom gyamuk. One of the rarest subspecies of bear in the world, the blue bear is rarely sighted in the wild. The blue bear is known in the West only through a small number of fur and bone samples. It was first classified in 1854. www.wikiwand.com/en/Tibetan_blue_bear The Gobi bear is sometimes classified as being of the same subspecies as the Tibetan blue bear; this is based on morphological similarities, and the belief that the desert-dwelling Gobi bear represents a relict population of the blue bear. However, the Gobi bear is sometimes classified as its own subspecies, and closely resembles other Asian brown bears.

The Tibetan blue bear is not actually blue. It is just the blue light they reflect at times depending on the weather.

奇怪的是,1990年代中国研究的藏棕熊数量为1.6w,数据由刘武林提供,刘武林也是中国部分藏棕熊体重数据的提供者。Attachments:

hwn says ( quote ) It is a dangerous and powerful animal in China. It is more common than amur bear in China. Be safe. I had read about the aggressive behavior of the Tibetan brown bear. But, I thought that they were exclusively high up in the Himalayan Mountains.

It seems the aggression of this bear is warranted. It even sneaks into houses.

Conflicts of human with the Tibetan brown bear (Ursus arctos pruinosus) in the Sanjiangyuan region, China www.sciencedirect.com/science/article/pii/S2351989419309138 Abstract Human-carnivore conflict (HCC) has become a major concern for both the management of protected areas and local community development worldwide. The occurrence and intervention of HCCs has been originated in duel context of the environment and social economy. In the Sanjiangyuan region of the Qinghai-Tibet Plateau, human-bear conflict (HBC) has emerged as a severe problem. Damages caused by Tibetan brown bears (Ursus arctos pruinosus) seriously threaten the livelihood and safety of local herders, decreasing community tolerance for brown bear conservation. A systematic field survey of HBC occurrences was undertaken in Zhiduo county of the Sanjiangyuan region in summer 2019. We surveyed 312 families via semi-structured interviews to understand the factors that contributed towards the likelihood of bear damage, representative conflict types, seasonal variation in damage occurrence, and mitigation measures deployed. The results showed that incidents of bear damage in the Sanjiangyuan region have elevated as a consequence of changes in the nomadic lifestyle of local herders. It is in part connected with simultaneous recovery of bear numbers following the conservation measures applied. Despite the widespread incidence of HBCs, with almost all respondents (n = 288, 92.31%) reporting occurrences of bear damage, most home damages were not compensated, and programs for such were lacking. Through the survey of the expected compensation types of local respondents, it was concluded that HBCs need to be mediated and resolved by integrated compensation schemes, physical and chemical prevention measures, and community development plans. Particularly, the local government should pay more attention to reducing family dependence on animal husbandry and transforming livelihood strategies into replaceable economic practices unrelated to grazing. These include things like ecological public welfare jobs and brown bear viewing ecotourism. *Complete article on site.

Identifying climate refugia and its potential impact on Tibetan brown bear (Ursus arctos pruinosus ) in Sanjiangyuan National Park, China onlinelibrary.wiley.com/doi/full/10.1002/ece3.5780 Abstract Climate change has direct impacts on wildlife and future biodiversity protection efforts. Vulnerability assessment and habitat connectivity analyses are necessary for drafting effective conservation strategies for threatened species such as the Tibetan brown bear (Ursus arctos pruinosus). We used the maximum entropy (MaxEnt) model to assess the current (1950–2000) and future (2041–2060) habitat suitability by combining bioclimatic and environmental variables, and identified potential climate refugia for Tibetan brown bears in Sanjiangyuan National Park, China. Next, we selected Circuit model to simulate potential migration paths based on current and future climatically suitable habitat. Results indicate a total area of potential suitable habitat under the current climate scenario of approximately 31,649.46 km2, of which 28,778.29 km2 would be unsuitable by the 2050s. Potentially suitable habitat under the future climate scenario was projected to cover an area of 23,738.6 km2. Climate refugia occupied 2,871.17 km2, primarily in the midwestern and northeastern regions of Yangtze River Zone, as well as the northern region of Yellow River Zone. The altitude of climate refugia ranged from 4,307 to 5,524 m, with 52.93% lying at altitudes between 4,300 and 4,600 m. Refugia were mainly distributed on bare rock, alpine steppe, and alpine meadow. Corridors linking areas of potentially suitable brown bear habitat and a substantial portion of paths with low-resistance value were distributed in climate refugia. We recommend various actions to ameliorate the impact of climate change on brown bears, such as protecting climatically suitable habitat, establishing habitat corridors, restructuring conservation areas, and strengthening monitoring efforts. _______________________________________________________________________________ CONCLUSION This study identified shifts in suitable habitat for Tibetan brown bears and the most important areas for connecting current and future habitat in the context of climate change. The Tibetan brown bear serves as an umbrella species, with its protection serving as a benefit for other sympatric wildlife. Applying this method to such species with relevant ecological information enables conservation biologists to develop precise climate-landscape conservation plans. Determining refugia and climate connectivity enable the identification of the most efficient regions to maintain brown bear populations and strengthen habitat connectivity.

Purported Yeti Samples Are Genetically Identical to Asian Bears, DNA Study Says The Yeti, a mysterious ‘hominid’-like creature said to inhabit the high mountains of Asia, looms large in the mythology of Nepal and Tibet. Now, a new DNA study of purported Yeti samples is providing insight into the origins of this legend. www.sci.news/biology/yeti-genetically-identical-asian-bears-05486.html “Our findings strongly suggest that the biological underpinnings of the Yeti legend can be found in local bears, and our study demonstrates that genetics should be able to unravel other, similar mysteries,” said Dr. Charlotte Lindqvist, a researcher at the University at Buffalo College of Arts and Sciences and Nanyang Technological University. Dr. Lindqvist and co-authors analyzed nine ‘Yeti’ specimens, including bone, tooth, skin, hair and fecal samples collected in the Himalayas and Tibetan Plateau. Of those, one turned out to be from a dog. The other eight were from Asian bears — one from an Asian black bear (Ursus thibetanus), one from a Himalayan brown bear (Ursus arctos isabellinus), and the other six from Tibetan brown bears (Ursus arctos pruinosus). “We investigated samples such as a scrap of skin from the hand or paw of a ‘Yeti’ — part of a monastic relic — and a fragment of femur bone from a decayed ‘Yeti’ found in a cave on the Tibetan Plateau,” the researchers said. “The skin sample turned out to be from an Asian black bear, and the bone from a Tibetan brown bear.” “The samples that we examined were provided by British production company Icon Films.” The team is not the first to research ‘Yeti’ DNA, but past projects ran simpler genetic analyses, which left important questions unresolved. “This study represents the most rigorous analysis to date of samples suspected to derive from anomalous or mythical ‘hominid’-like creatures,” the scientists said. Besides tracing the origins of the Yeti legend, the study is uncovering information about the evolutionary history of Asian bears. “Bears in this region are either vulnerable or critically endangered from a conservation perspective, but not much is known about their past history,” Dr. Lindqvist said. “The Himalayan brown bears, for example, are highly endangered. Clarifying population structure and genetic diversity can help in estimating population sizes and crafting management strategies.” The researchers sequenced the mitochondrial DNA of 23 Asian bears (including the purported Yetis), and compared this genetic data to that of other bears worldwide. This analysis showed that while Tibetan brown bears share a close common ancestry with their North American and Eurasian kin, Himalayan brown bears belong to a distinct evolutionary lineage that diverged early on from all other brown bears. The split occurred about 650,000 years ago, during a period of glaciation, according to the study. The timing suggests that expanding glaciers and the region’s mountainous geography may have caused the Himalayan bears to become separated from others, leading to a prolonged period of isolation and an independent evolutionary path. The findings are published in the journal Proceedings of the Royal Society B. Tianying Lan et al. 2017. Evolutionary history of enigmatic bears in the Tibetan Plateau–Himalaya region and the identity of the yeti. Proc. R. Soc. B 284 (1868): 20171804; doi: 10.1098/rspb.2017.1804
