Hunter, D. (1997). Mongolian-American Snow Leopard Project. Cat News, 26, 15–16.
Abstract: A snow leopard project is underway to study snow leopards in Mongolia. The project, called the Mongolian-American Snow Leopard Project, involves the Wildlife Conservation Society, the Mongolian Association for the Conservation of Nature and Environment, the National Geographic Society, the Mongolian Ministry of Nature and the Environment, the U.S. National Biological Service, and the International Snow Leopard Trust. The objective of the study is to survey the distribution and status of Mongolia's snow leopards, including those living in the Gobi Desert. klf.

Yu, N. Z. C., Wang, X., He, G., Zhang, Z., Zhang, A., Lu, W., et al. (1996). A revision of genus Uncia Gray, 1854 based on mitochondrial DNA restriction site maps. Acta Theriologica Sinica, 16(2), 105–108.
Abstract: The Snow leopard (Panthera uncia) is one of the most threatened wild big cats within its range of distribution, however, the question of its systematic status is a matter of debate. Is it a member of genus Panthera, or is it in its own genus (Uncia)? The analysis of genetic difference at the DNA level may provide useful data to clarify the issue. In the present study, ten hexanucleotide-specific restriction endonucleases were used to evaluate the patterns of mitochondrial DNA variation between the Snow leopard and leopard (P. pardus). The molecular size of mtDNA from the two species was about 16.5 kb. Ten enzymes surveyed 32-34 restriction sites, which corresponded to 192 apprx 204 base pairs, or 1.16% apprx 1.24% of the total mtDNA molecule. A total of 45 restriction sites were mapped; of these sites, twenty-four, which correspond to 53.3% of the total sites, were variable. The sequence divergence between them was 0.075 33, which was undoubtedly in the species-level distinction but did not reach the genus level. Therefore, the Snow leopard should be placed in the genus Panthera rather than in its own ganus. It also seems reasonable to recognize Uncia as a valid subgenus. This conclusion not only support but also supplement the viewpoint of Simpson who treated Uncia as a subgenus within Panthera.

Oli, M. K. (1996). Seasonal patterns in habitat use of blue sheep Pseudois nayaur (Artiodactyla, Bovidae) in Nepal. Mammalia, 60(2), 187–193.
Abstract: Blue sheep (Pseudois nayaur) are the main prey of the endangered snow leopard (Panthera uncia) as well as an important game species in Nepal. A knowledge of how blue sheep utilize their habitat is essential for the scientific management of the sheep and for the conservation of the snow leopard, but we only have a limited understanding of this aspect of blue sheep ecology. I studied the habitat use pattern of blue sheep by direct observation in the Anna-purna Conservation Area, Nepal where they occur sympatrically with the snow leopard. The sheep used grassland habitats more frequently during pre-parturition (spring) and post-parturition (autumn) than other habitat types, but scrub and grassland habitats were used equally frequently during the rut (winter). The sheep used smooth undulating slopes of medium steepness (<40 degrees) on southerly aspects within the elevation range of 4,200-4,600 m most frequently in all seasons, and there was no evidence of seasonal migration along the elevation gradient. When not in broken landforms (e.g., cliff, landslides), the sheep maintained proximity (less than or equal to 150 m) to such features suggesting their importance as escape cover (i.e., from predators). The use of habitat components by blue sheep appeared to be related to the distribution of foraging areas and escape cover.

Oli, M. K., & Rogers, E. M. (1996). Seasonal pattern in group size and population composition of blue sheep in Manang, Nepal. Journal of Wildlife Management, 60(4), 797–801.
Abstract: Blue sheep (Pseudois nayaur) are the principal prey of the endangered snow leopard (Panthera uncia) in the Himalayas and adjacent ranges. We studied group size and population composition of blue sheep in Manang District, Annapurna Conservation Area, Nepal. Overall mean group size was 15.6 (SE = 1.3), but it varied seasonally (P lt 0.001), with significantly smaller groups in winter than in other seasons. Mixed groups were most numerous in all seasons, and there was no evidence of sexual segregation. Yearling sex ratio (93.7 M:100 F) did not vary seasonally, nor did the ratio deviate from parity. Adult sex ratio showed a seasonal pattern favoring males post-parturition but female-biased during the rut and pre-parturition. Seasonal variation in sex-specific mortality is offered as a plausible explanation for the observed pattern in adult sex ratio.

Koshkarev, E. (1996). The snow leopard in its northeastern range. Cat News, 25, 10.
Abstract: The author surveyed three sites in the central and eastern Sayan regions of Russia for snow leopards. In the Zhombolok River Basin of the Kropotkinskiy and Okinskiy Mountains, the author found seven snow leopard tracks, representing five or six individuals. In the Munku-Sardyk Peak area, one snow leopard track was found, and in the Tunkinskiy Ranffe area three tracks, representing at least two animals, were found. Other information is provided on local sightings. klf

Abstract: Public attitudes towards snow leopard Panthera uncia predation of domestic livestock were investigated by a questionnaire survey of four villages in snow leopard habitat within the Annapurna Conservation Area, Nepal. Most local inhabitants were subsistence farmers, many dependent upon yaks, oxen, horses and goats, with an average livestock holding of 26.6 animals per household. Reported losses to snow leopards averaged 0.6 and 0.7 animals per household in two years of study, constituting 2.6% of total stockholding but representing in monetary terms almost a quarter of the average annual Nepali national per capita income. Local people held strongly negative attitudes towards snow leopards and most suggested that total extermination of leopards was the only acceptable solution to the predation problem. Snow leopards were reported to be killed by herdsmen in defence of their livestock. The long-term success of snow leopard conservation programmes may depend upon the satisfactory resolution of the predation conflict. Some possible ways of reducing predation losses are also discussed.

Oli, M. K. (1993). A key for the identification of the hair of mammals of a snow leopard (Panthera uncia) habitat in Nepal. Journal of Zoology London, 231(1), 71–93.
Abstract: Analysis of prey remains in scats, particularly hairs, in widely used to study diet of mammalian predators, but identification of hair is often difficult because hair structures vary considerably both within and between species. Use of photographic reference of diagnostically important hair structures from mammals occurring in a predator's habitat has been found to be convenient for routine identification. A photographic reference key was developed for the identification of hairs of the mammals known to occur in a snow leopard (Panthera uncia) habitat in the Annapurna Conservation Area, Nepal. The key included a photographic reference of the diagnostic hair structures of nine species of wild and five species of domestic mammals. The cross-sectional appearance, shape and arrangement of medulla, the ratio of cortex to medulla, and the form and distribution of pigment in medulla and cortex were important diagnostic aids in the identification of hairs.

Salles, L. O. (1992). Felid phylogenetics: Extant taxa and skull morphology (Felidae, Aeluroidae). American Museum Novitates, (3047), 1–67.
Abstract: relationships among extant felid taxa are controversial. A historical appraisal addresses component congruence among statements on felid phylogenetic relationships, and monophyly of generic ranks proposed for felids is discussed. Felid cranial morphology (especially the masticatory apparatus, basicranium, and rostral regions) is examined, and 44 characters are postulated for 39 taxa. Internal congruence for these characters is evaluated and 27 components are suggested. Parsimony analysis, using the successive weighting option of Hennig86, of the 44 cranial characters plus 13 other morphological features yields 29 components in a “modified Nelson” consensus cladogram. Two basal, well resolved clades are hypothesized in the total morphology analysis; under parenthetical notation the first is: (Hepailurus yagouaroundi (Puma concolor (Acinonyx jubatus (Uncia uncia (Neofelis nebulosa (Panthera tigris (P. onca, P. leo, and P. pardus)))))). The second clade is: Profelis temmincki (P. badia (Pardofelis marmorata ((Caracal caracal (Lynx rufus (L. lynx (L. pardina (L. canadensis)))) (Felis chaus (F. lybica (L. cafra (L. silvestris (F. bieti (F. nigripes (F. margarita (Octocolobus manul)))))))). Prionailurus planiceps and P. viverrina formed another group which is suggested as the basal branch of the felid phylogeny. The results in this study do not support monophyly of Leopardus Gray, 1841; Profelis Severtzon, 1858; and Prionailurus Severtzon, 1858. A better supported, more highly resolved, felid phylogenetic tree is needed.
