Sokov A.I. (1986). Environmental prerequisites for protection and sustainable use of predatory mammals in Tajikistan (Vol. Vol. 3.).
Abstract: In Tajikistan it is necessary to preserve big predators listed in the Red Book, such as Uncia uncia, Ursus arctos isabellinus, Hyaena hyaena, Felis lynx isabellina, Panthera pardus ciscaucasica. An anthropogenic influence has resulted in the species' habitat shrinkage, deficit of food, disturbance of trophic interactions. It is necessary to restore a tiger population in the Tigrovaya Balka nature reserve, and resolve the issue of protection and sustainable use of commercial predatory species.

Sokolov G.A. (2003). Predatory mammals of Central Siberia, status of populations, influence of anthropogenic factors.
Abstract: The species resources of Siberia's fauna decrease from south to north. The highest diversity of species is observed in the mountain systems, the lowest in sub-zones of south and central taiga and steppe zone, where the cat family species are absent. During the last 50 150 years number of species has decreased two- to tenfold. Imperfect hunting management, farming, and mining operations resulted in transformation of the animal habitats. Population of fox, polecat, and sable has reduced; snow leopard and dhole becoming endangered species. If current tendencies continue to develop some species will disappear in the region in decades to come.

Sokolov V.E. (1990). The Sary Chelek nature reserve.
Abstract: It provides general information about the Sary Chelek nature reserve (Kyrgyzstan), its physico-geographical features, and description of flora and fauna. Fauna of mammals includes over 40 species. A lot of work has been done in the nature reserve in order to protect rare species, including predators such as snow leopard, lynx, and bear. Snow leopard keeps to highlands, sometime entering into the forest zone. It was observed near lake Sary-Chelek. The following ungulate species inhabit the nature reserve: wild boar, ibex, and roe-deer. Population of wild boar consists of 700 800 animals, ibex 350 400, roe-deer 300 animals.

Sokolov V.E. (1986). Snow leopard.
Abstract: Snow leopard is an endangered species. Its number is steadily decreasing. In the USSR, snow leopard is distributed in the mountains of Central Asia: Pamir, Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur. It is also met at altitudes ranging from 1,800 3,500 m above sea level. A total number of snow leopard in the USSR does not exceed 1,000 animals; according to other data 2,000 animals. A decreasing number of snow leopard and its habitat shrinkage is directly related to human's pursuing snow leopards (in the USSR snow leopard was for a long time being considered as a species causing damage to livestock so authorities gave premiums for catching/shooting snow leopards) and reduction of ungulate population. Snow leopards are now protected in mountain nature reserves of the USSR: Chatkal, Aksu-Djabagly, Ramit, Besh-Aral, Sary-Chelek, and Alma-Ata.

Sobanskiy G.G. (1988). The cat family. Snow leopard, or irbis.
Abstract: In the Altai, there are three cat family species: snow leopard, lynx, and manul. Several tens of snow leopards inhabiting the area along river Argut and its tributaries remained in Altai. They are rarer met in south Altai along the Chikhachev, Shapshal, and Sailyughem ridges. They prey on ibex, wild sheep, roe deer, and moral. They can also attack livestock but would never kill more than one animal.

Sludskiy A.A. (1982). Mammals.
Abstract: The author describes the lot of extinct and endangered mammal species inhabitants of various continents. Over the last 2,000 years, on the territory now occupied by the USSR, 11 species and sub-species of mammals died away and several dozens of species and sub-species are now endangered or rare and require special conservation measures. Big Felidae species include tiger (150 170 animals), leopard (38-48 animals, of which 20-25 permanently live in the Far East, the rest migrating), snow leopard, whose population reduced drastically (about 1,000 animals), caracal, Central Asia lynx, and manul.

Sludskiy A.A. (1973). Snow leopard or irbis Pantera (Uncia) uncia Schreber (1776) (Vol. Vol. 34. Hunting mammals of Kazakhstan).
Abstract: A detailed description of the snow leopard habitat in Turkmenistan, Tajikistan, Uzbekistan, Kyrgyzstan, Kazakhstan, Mongolia, China, Pakistan, and India is given. Provided are data concerning its distribution and population size in the USSR, Kazakhstan and other neighbour countries, as well as its habitat, catching, and fur trade. Reduction of the snow leopard catching volumes for zoological trade to 10 or less animals is recommended to preserve the species; establish two new highland nature reserves; improve the management of snow leopard raising in captivity.

Shnitnikov V.N. (1936). Rocks and taluses. Snow leopard, Irbis Felis irbis Shreb.
Abstract: In Semerechie, snow leopard is not a rare species. In 1931, 53 snow leopards were hunted in southern Semerechie. In the past, at the markets of Central Tien Shan one could buy skins or live snow leopards, which were in demand abroad. Probably, number of snow leopards in Semerechie has increased. Now, it can be found not only in remote areas but in the vicinity of settlements (snow leopards, for instance, were observed some 20 30 km from Almaty, and 60 km from Frunze). Snow leopard preys mainly on ibex (¥…dr… sibiri¤…), snow-cock (O†traogallus himalauenses), and numerous argali – in some areas. The animal will never attack a man, even if wounded.

Shnitnikov V.N. (1934). Rocks and taluses. Alpine meadows. Economic value of local animals (Vol. Part. 1. South Kazakhstan.).
Abstract: It reviews fauna of rocks, taluses, and alpine meadows of South Kazakhstan. The most typical mammal of rocks and taluses are picas (I¤hotona rutila and I. macrotis), ibex (¥…dr… sibirica), and snow leopard (Felis irbis). Besides, snow leopard, along with Tien Shan bear (Ursus l†u¤Œn¢o), ibex, mountain wolf (¥uŒn alpinus) and others, is met in the alpine meadow zone. Zoo-export of snow leopards to the zoos does not result in extermination of the animals but generates income. Various animal species are subject to trade as zoos do not limit their collections with some specific species or groups; quite the contrary they are interested in obtaining each species. Valuable animals exported from Kazakhstan are tiger, snow leopard, Tien-Shan bear, argali, and mountain wolf. The latter costs 1,000 roubles in gold, and argali even 1,500 roubles.

Sheikin A.O. (1996). Fleas of the carnivores of Kazakhstan (preliminary results of the data 1970-1888).
Abstract: The analysis of the data of national collection of Parasitological museum of Kazakh Antiplague Institute on ectoparasites from 12 species of carnivores that can be found in Kazakhstan: caracal, snow leopard, ermine, mountain weasel etc. helped to determine the species of fleas and their hosts specialization. Fleas were found on 57 animals/ 50 species of fleas were found, which can be specified to 23 genera, the total number is 525. The specific ones for the carnivores are 6 species fleas. The very low density of ectoparasites was indicated for caracal and snow leopard.

Abstract: The snow leopard Panthera uncia is one of the least studied felids in the world. Little is know about various aspects of the ecology of the snow leopard, which is cryptic in nature and found across 12 countries in Central Asia. Most research on snow leopards has been based on non-invasive methods such as sign surveys for presence (e.g. Jackson and Hunter 1996), scat analyses for diet (e.g. Chundawat and Rawat 1992; Oli et al., 2008, 2010) for population estimation, and studies based on human interviews (Mehta and Heinen 2001; Mishra and Bagchi 2006).
Despite this plethora of studies employing non-invasive techniques, several crucial questions about snow leopard ecology remain unanswered. Information about the animal’s home range, dispersal, corridors, pattern of habitat use, movement patterns, hunting frequency, behavior and intra – specific interactions is not available yet. In order to design population monitoring studies using camera traps or DNA analyses, one needs a good understanding of snow leopard ecology, including the home range and movement patterns (Williams et al., 2002). Telemetry is still the best available method and perhaps much less invasive than direct observations for studying the biology and ecology of cryptic animals.

Schaller, G. B. (1987). Status of large mammals in the Taxkorgan Reserve, Xinjiang, China. Biological-Conservation, 42(1), 53–71.
Abstract: A status survey of large mammals was conducted in the W half of 14 000 km“SUP 2” Taxkorgan Reserve. Only one viable population of fewer than 150 Marco Polo sheep Ovis ammon poli survives; it appears to be augmented by adult males from Russia and Afghanistan during the winter rut. Asiatic ibex Capra ibex occur primarily in the western part of the reserve and blue sheep Pseudois nayaur – the most abundant wild ungulate – in the E and SE parts. The 2 species overlap in the area of contact. Counts revealed an average wild ungulate density of 0.34 animals km“SUP -2”. Snow leopard Panthera uncia were rare, with possibly 50-75 in the reserve, as were wolves Canis lupus and brown bear Ursus arctos. The principal spring food of snow leopard was blue sheep (60%) and marmot (29%). Local people have greatly decimated wildlife. Overgrazing by livestock and overuse of shrubs for fuelwood is turning this arid steppe habitat into desert. -from Authors
