why is the himalayan wolf endangered

However, the populations are still suffering heavy mortality. The Himalayan wolf lives in packs of five animals on average – a smaller group than grey wolves – and eats marmots in summer as well as woolly hares and bharal, or Himalayan blue sheep. The group determined that the earliest available Latin name is Canis chanco Gray, 1863, but the geographic location of the holotype is unclear. Conservation scientists do not know the wolf’s population because it roams across a large swath of inaccessible terrain. In 1974, the gray wolf was officially considered endangered. Himalayan wolves avoided livestock where wild prey is available, but habitat encroachment and the depletion of wild prey populations is forecast to lead to conflict with herders. We do not guarantee individual replies due to extremely high volume of correspondence. [7][23] Subsequent genetic research showed that wolf samples from Tibet are genetically basal to the Holarctic gray wolf. The animal survives on half the oxygen available to mammals at sea level. The African golden wolf was found to be the descendant of a genetically admixed canid of 72% grey wolf and 28% Ethiopian wolf ancestry.

[22] [8], The mitochondrial DNA of 27 wolves from the Himalayas and the Tibetan Plateau was compared in 2004. The committee stated that the classification was for conservation purposes only, and did not "reflect the latest state of taxonomic knowledge". "These genetically distinct Himalayan wolves deserve special conservation attention, at the same time that the conservation of this species in a context of human-wildlife conflict is challenging," conclude the scientists. [50], Historical sources indicate that wolves occasionally killed children in Ladakh and Lahaul. In India, the wolf is protected under Schedule I of the Wildlife Protection Act, 1972, which prohibits hunting; a zoo needs a permission from the government to acquire a wolf. 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 wolf, and has an association with the African golden wolf (Canis anthus). Their findings are published in the open access journal ZooKeys. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. The wolves in the study formed three clades: north Asian wolves that included those from northern China and eastern Russia, wolves from the Tibetan Plateau, and a unique population from southern China. [40] It has closely spaced black speckles on the muzzle, below the eyes, and on the upper cheeks and ears. [26], Two studies of the mitochondrial genome of both modern and extinct grey wolves (Canis lupus) have been conducted, but these excluded the genetically divergent lineages of the Himalayan wolf and the Indian wolf. The wolves surviving at high altitudes in Nepal and on the Tibetan plateau possess a genetic adaptation to cope with the lack of oxygen that is not found in any other wolf, a study reports. [8], In northern India, it occurs in the Ladakh region of eastern Kashmir[39] and in the Lahaul and Spiti region in northeastern Himachal Pradesh. [7][19] The committee recommended against this proposal, but suggested that the name be entered into the CITES species database as a synonym for Canis lupus. For many, they aren’t nearly as important as some of the other animals out there that are on this same list. Thank you for taking your time to send in your valued opinion to Science X editors. [4] There was evidence of hybridization with the grey wolf at Sachyat-Ertash in the Issyk-Kul region of Kyrgyzstan, and of introgression from either the grey wolf or the dog into the Himalayan wolf in Nepal. They were persecuted and killed as a means of depredation. The most ancient wolf lineage, known to science, has been listed as Critically Endangered in the National Red List. [31], The Tibetan Mastiff was able to adapt to the extreme highland conditions of the Tibetan Plateau very quickly compared to other mammals such as the yak, the Tibetan antelope, the snow leopard, and the wild boar. 1 Annex 1", "Megafaunal Extinctions and the Disappearance of a Specialized Wolf Ecomorph", "Phylogeographic history of grey wolves in Europe", "Worldwide patterns of genomic variation and admixture in gray wolves", "Genomic Approaches Reveal an Endemic Subpopulation of Gray Wolves in Southern China", "Genomic Analysis Reveals Hypoxia Adaptation in the Tibetan Mastiff by Introgression of the Grey Wolf from the Tibetan Plateau", "Adaptive Changes in Hemoglobin Function in High-Altitude Tibetan Canids Were Derived via Gene Conversion and Introgression", "Interspecific Gene Flow Shaped the Evolution of the Genus, "Woolly Wolf Spotted in Nepal Is Likely a New Species", "Howl variation across Himalayan, North African, Indian, and Holarctic wolf clades: tracing divergence in the world's oldest wolf lineages using acoustics", "Dietary spectrum in Himalayan wolves: comparative analysis of prey choice in conspecifics across high-elevation rangelands of Asia", "Local villagers' perceptions of wolves in Jiuzhaigou County, western China", https://en.wikipedia.org/w/index.php?title=Himalayan_wolf&oldid=979088274, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, Himalayan wolf distribution (red dots in highlands) compared with the holarctic grey wolf (blue dots in lowlands), This page was last edited on 18 September 2020, at 18:28. The most ancient wolf lineage, known to science, has been listed as Critically Endangered in the National Red List. In China, the wolf is listed as vulnerable in the Red List of China’s Vertebrates, and hunting it is banned. Himalayan wolf lopes towards recognition as distinct species. part may be reproduced without the written permission. It was identified as an evolutionary significant unit that warranted assignment onto the IUCN Red List for its protection. The Himalayan wolf lacks a proper morphological analysis.[3]. [2] The endangered wolf that walked 8,712 miles to find love. Click here to sign in with [19] Fecal remains of four wolves collected in the upper Mustang region of the Annapurna Conservation Area also fell within the Himalayan wolf clade but formed a separate haplotype from those previously studied. When compared to the European wolf, this one stands out with its smaller size, unusually longer muzzle and stumpy legs. [32][33], In 2011, the Indian wolf, Himalayan wolf, and African golden wolf were proposed to represent ancient wolf lineages, with the African golden wolf having colonised Africa prior to the Northern Hemisphere radiation of the Holarctic grey wolf. In Nepal, it is protected under Schedule I of the National Parks and Wildlife Conservation Act, 2029 (1973) prohibiting hunting it. Neither your address nor the recipient's address will be used for any other purpose. [23] It weighs about 35 kg (77 lb). The Himalayan and North African wolves have the most acoustically distinct howls and differ significantly from each other and the Holarctic wolves. Come learn about the reasons why they became endangered and how people are trying to stop them from disappearing from the wild. Many species of wolves continue to be endangered at this point in time. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. [7] Lack of information about its basic ecology in this landscape is an obstacle for developing a conservation plan. As this study was based on captive-bred zoo specimens that had descended from only two females, these samples were not considered to be representative. However, the distinctiveness of the Himalayan wolf is far more than skin-deep. The Himalayan wolf (Canis lupus chanco)[3] is a canine of debated taxonomy. The ancient specimens were radiocarbon dated and stratigraphically dated, and together with DNA sequences, a time-based phylogenetic tree was generated for wolves. chanco. In 2020, further research on the Himalayan wolf indicates that it warrants species-level recognition under the Unified Species Concept, the Differential Fitness Species Concept, and the Biological Species Concept. This genetic lineage shows a 3.9% divergence in the mDNA cytochrome b gene when compared with the Holarctic grey wolf, which may justify it being classified as a distinct species. It prefers wild species but will also take livestock. Grey wolves are a kind of wolf that used to live all over North America. in 2007 for wolf specimens from the Indian Himalayas that differed in mitochondrial DNA from specimens collected in other parts of India. Grey wolves are unable to move in and take over such inhospitable territory. chanco. Provided by [36] The Ethiopian wolf does not share the single-nucleotide polymorphisms that confer hypoxia adaptation with the Himalayan wolf. On this tree, the term “basal” is used to describe a lineage that forms a branch diverging nearest to the common ancestor. The proposal was based on one study that relied on only a limited number of museum and zoo samples that may not have been representative of the wild population. Apart from any fair dealing for the purpose of private study or research, no Results indicate that five related haplotypes formed a clade that is basal to all other wolves. [7], The heart of the Himalayan wolf withstands the low oxygen level at high elevations. It probably recolonised the Tibetan Plateau. In fact, wolves were imported from Canada to help increase the number of them and stimulate breeding. [7] [48], Himalayan wolves prefer wild over domestic prey. [54] [23], The Himalayan wolf population in Tibet declined over the past 25,000 years and suffered a historical population bottleneck. Although the Himalayan wolf is visibly distinct from its European cousin, its current distribution has mostly been a matter of assumption, rather than evident truth. The adaptation of the Ethiopian wolf to living in high elevations may occur at other single-nucleotide polymorphism locations. [3] The mtDNA of 18 captive wolves in the Padmaja Naidu Himalayan Zoological Park was analysed in 2007. Seven wolves from Kashmir did not fall into this clade. [24][9][10][25][26][27][6][4][5][2] Its MT-ND4L gene commences with the base pairs GTG, whereas all other canids commence with ATG. [18], Canis himalayensis was proposed by Aggarwal et al. This document is subject to copyright. or, by Pensoft Publishers. The wolves killed horses significantly more, and goats less, than would be expected from their relative abundance. Results showed that they shared a common female ancestor. [7] The Himalayan wolf lineage can be found living in the Himalayas and the Tibetan Plateau predominantly above 4,000 m in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations. Although the Himalayan wolf is visibly distinct from its European cousin, its current distribution has mostly been a matter of assumption, rather than evident truth. Animal’s unique adaptation to low-oxygen life can be basis for protection, say researchers, Last modified on Fri 21 Feb 2020 07.19 EST.
