Himalayan wolf
The Himalayan wolf (Canis lupus chanco) is a canine of debated taxonomy. 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 and Mongolian wolf, and has an association with the African wolf (Canis lupaster). No striking morphological differences are seen between the wolves from the Himalayas and those from Tibet. The Himalayan wolf lineage can be found living in Ladakh in the Himalayas, the Tibetan Plateau, and the mountains of Central Asia predominantly above 4,000 m (13,000 ft) in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations.
Some authors have proposed the reclassification of this lineage as a separate species. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group recommends that this wolf lineage be known as the "Himalayan wolf" and be classified as Canis lupus chanco until a genetic analysis of the holotypes is available. The Himalayan wolf lacks a proper morphological analysis. The wolves in India and Nepal are listed on CITES Appendix I as endangered due to international trade.
Canis chanco was the scientific name proposed by John Edward Gray in 1863, who described a skin of a wolf that was shot in Chinese Tartary. This specimen was classified as a wolf subspecies Canis lupus chanco by St. George Jackson Mivart in 1880. In the 19th and 20th centuries, several zoological specimens were described:
In 1938, Glover Morrill Allen classified these specimens as synonyms for C. l. chanco. In 1941, Reginald Pocock corroborated this assessment after reviewing wolf skins and skulls in the collection of the Natural History Museum, London. In 2005, W. Christopher Wozencraft also listed C. l. niger, C. l. filchneri, C. l. karanorensis, and C. l. tschiliensis as synonyms for C. l. chanco.
Canis himalayensis was proposed by Aggarwal et al. in 2007 for wolf specimens from the Indian Himalayas that differed in mitochondrial DNA from specimens collected in other parts of India. In April 2009, Canis himalayensis was proposed as a distinct wolf species through the Nomenclature Specialist on the CITES Animals Committee. 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. The committee recommended against this proposal, but suggested that the name be entered into the CITES species database as a synonym for Canis lupus. The committee stated that the classification was for conservation purposes only, and did not "reflect the latest state of taxonomic knowledge". Further fieldwork was called for. 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. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group determined that the earliest available Latin name is Canis chanco Gray, 1863, but the geographic location of the holotype is unclear. The group recommends that this wolf lineage be known as the "Himalayan wolf" and classified as Canis lupus chanco until a genetic analysis of the holotypes is available.
In 2020, more recent research on the Himalayan wolf genome indicates that it warrants species-level recognition under the Unified Species Concept, the Differential Fitness Species Concept, and the Biological Species Concept. It was identified as an evolutionary significant unit that warranted assignment onto the IUCN Red List for its protection.
The Himalayan wolf has a thick, woolly fur that is dull earthy-brown on the back and tail, and yellowish-white on the face, tummy, and limbs. It has closely spaced black speckles on the muzzle, below the eyes, and on the upper cheeks and ears.
Larger than the Indian and common European wolves, it reaches 110 to 180 cm (45 to 70 in) in length, 68 to 76 cm (27 to 30 in) tall at the shoulder, and weighs around 30 to 55 kg (66 to 121 lb) on average.
