McCarthy, K., Fuller, T., Ming, M., McCarthy, T., Waits, L., & Jumabaev, K. (2008). Assessing Estimators of Snow Leopard Abundance (Vol. 72).
Abstract: The secretive nature of snow leopards (Uncia uncia) makes them difficult to monitor, yet conservation efforts require accurate and precise methods to estimate abundance. We assessed accuracy of Snow Leopard Information Management System (SLIMS) sign surveys by comparing them with 4 methods for estimating snow leopard abundance: predator:prey biomass ratios, capture-recapture density estimation, photo-capture rate, and individual identification through genetic analysis. We recorded snow leopard sign during standardized surveys in the SaryChat Zapovednik, the Jangart hunting reserve, and the Tomur Strictly Protected Area, in the Tien Shan Mountains of Kyrgyzstan and China. During June-December 2005, adjusted sign averaged 46.3 (SaryChat), 94.6 (Jangart), and 150.8 (Tomur) occurrences/km. We used
counts of ibex (Capra ibex) and argali (Ovis ammon) to estimate available prey biomass and subsequent potential snow leopard densities of 8.7 (SaryChat), 1.0 (Jangart), and 1.1 (Tomur) snow leopards/100 km2. Photo capture-recapture density estimates were 0.15 (n = 1 identified individual/1 photo), 0.87 (n = 4/13), and 0.74 (n = 5/6) individuals/100 km2 in SaryChat, Jangart, and Tomur, respectively. Photo-capture rates
(photos/100 trap-nights) were 0.09 (SaryChat), 0.93 (Jangart), and 2.37 (Tomur). Genetic analysis of snow leopard fecal samples provided minimum population sizes of 3 (SaryChat), 5 (Jangart), and 9 (Tomur) snow leopards. These results suggest SLIMS sign surveys may be affected by observer bias and environmental variance. However, when such bias and variation are accounted for, sign surveys indicate relative abundances similar to photo rates and genetic individual identification results. Density or abundance estimates based on capture-recapture or ungulate biomass did not agree with other indices of abundance. Confidence in estimated densities, or even detection of significant changes in abundance of snow leopard, will require more effort and better documentation.

Matyushkin E.N. (1984). Snow leopard, or irbis Uncia uncia Scheber, 1775 (Vol. Vol.1.).
Abstract: Snow leopard Uncia uncia Scheber, 1775, was included in the Red Data Book of the USSR and given status III rare species with small habitat. It provides information about its distribution (from Pamir and West Tien Shan to East Sayans), habitat, biology, number, threats, and existing and required protection measures. Total number in the USSR is about 2,000 animals. There were 194 snow leopards in the zoos throughout the world at the beginning of 1980. In the USSR the species is under protection in nature reserves as follows: Ramit, Chatkal, Besh Aral, Aksu Jabagly, Sary Chelek, Almaty, Altai.

Marma B.B.and Yunchis V.V. (1968). A contribution to biology of the Snow-leopard (Panthera uncia uncia) (by observations in captivity) (Vol. XLVII, issue 11.).
Abstract: The methods to obtain the progeny of the snow leopard (Panthera uncia uncia) in captivity were being elaborated in the zoological garden of Kaunas, Lithuanian SSR. The blood characteristics for snow leopards is given and compared to that for African lions and Sumatrian tigers. A series of internal, external and clinical indices is established. The rat lasts for 5-7 day, the duration of pregnancy equals 98 days. The duration of lactation varies from 3 to 4 months. Sexual maturity is attained on the 3rd-4th year. From 1960 to 1967 in zoological garden of the world about 29 snow leopards were born, 14 of them in the Kaunas zoological garden.

Mallon, D. P. (1991). Status and Conservation of Large Mammals in Ladakh. Biological Conservation, 56(1), 101–119.
Abstract: The distribution and status of large mammals was surveyed in a 15 000 km2 study area in Ladakh, India. Snow leopard Panthera uncia, wolf Canis lupus, ibex Capra ibex and bharal Pseudois nayaur have an almost continuous distribution throughout; Ladakh urial Ovis vignei, Tibetan argali Ovis ammon, wild ass Equus kiang and brown bear Ursus arctos have a limited distribution. Snow leopard prefer lower altitudes and rocky, undisturbed areas. Ibex and bharal occupy similar rocky habitats but their ranges are mostly separate, with a small area of overlap. The Ladakh urial shows signs of recovery from an earlier decline. Natural resources are widely used for fuel, fodder and grazing, but favourable factors include a low human population, low level of hunting and the existence of some uninhabited and undisturbed areas. A comprehensive Protected Area Network has been proposed.

Mallon, D. (1984). The Snow Leopard, Panthera uncia, in Mongolia. Int.Ped.Book of Snow Leopards, 4, 3–9.
Abstract: In the International Pedigree Book of Snow Leopards 3, Blomqvist and Sten notes (1982) that no information had been recieved on the snow leopard in Mongolia. The present paper sets out to repair that omission by summarising the information in print on snow leopards in Mongolia and giving a brief account of its distribution in the country. This is essentially a review paper and it is hoped that more precise data may be obtained from fieldwork carried out in the future by Mongolian zoologist. The author worked in Mongolia for two years 1975-1977, and during that time collected information on mammals of Mongolia. Information on the snow leopard was obtained from colleagues at the State University of Mongolia; from zoologists and hunters; from herdsmen and local informants from all parts of the country and from three journeys made by the author: to the eastern Gobi Altai; the Khangai mountains, and a 2000 km journey through western Altai. In this paper, the term “Mongolia” refers to the territory of the Mongolian peoples Republic
