Dementiev G.P. (1969). Mammals.
Abstract: It provides a list and discusses a status of rare and endangered predators and ungulates in the USSR (24 species in total). Snow leopard inhabits the mountain ridges of Tajikistan and Kyrgyzstan, in the Altai and Tuva. The habitat of snow leopard had not changed significantly since recently, though its population had been reducing (according to materials of the year 1967). Such reduction of its population is because of the common assumption of its harmfulness and high demand for its fur-skin and high prices that zoos would readily pay for the animals.

Cherkasova M.V. (1982). Predators.
Abstract: Among species included in the Red Data Book of the USSR, predators occupy the first place; of them, unconditional leadership belongs the cat family species. Nine of eleven species of the family are referred to as rare and endangered ones. In the past snow leopard (Uncia uncia) inhabited all mountains on the south of the USSR from Tien Shan and Pamir to Transbaikalia. Now it no longer inhabits many of its previous habitats and has become rare, everywhere. Its total population in the USSR is no more than 1000 animals. At the beginning of XX century there were cases that such an amount of snow leopard (i.e. 1,000) was hunted during one year. Until recently, hunting the species was allowed all year round and even encouraged.

Bogdanov O.P. (1992). Snow leopard or irbis Uncia Uncia.
Abstract: Snow leopard and its habitat within the USSR and Uzbek SSR are described. Its habitat in the Chatkal and Hissar ridges are described too. Given are data concerning alimentary biology, reproduction, and attitude to man. Female snow leopards become mature at the age of two three years, male at the age of four years. Reproduction occurs once every two years. Presumably, there are 10 animals in the country. Snow leopard is protected in four nature reserves in Uzbekistan and a number of nature reserves in neighbour countries.

Egorov O.V. (1955). Enemies, infections, parasites and mortality rate of ibex (Vol. Vol. 42.).
Abstract: Reasons for ibex and argali mortality from natural enemies, parasites, infections, accidents, and hunters are analyzed. Snow leopard is one of the most dangerous enemies of ibex and argali, preying equally on both young and mature animals (mostly males). Snow leopard feeds upon ibex all year round. Unlike wolf, snow leopard would never kill several animals at a time, but only one selected victim. The food remains left by these predators are different in terms of the skull gnawing. Nasal bones and eye-sockets on the skull of ibex killed by snow leopard remain undamaged, while wolf gnaws off nasal part of the skull, breaks eye-sockets, eats lower jaw, widens occipital hole and pulls out brains. Snow leopard leaves large pieces of skin around the skeleton of the victim, whereas wolf tears it to shreds or eats up fully. Sometimes parts of the victim left by snow leopard are eaten by wolf. It is easy to mix the remains of snow leopard's or griffon vulture's food. The remains differ in skin being turned inside out rather than torn to large pieces.

Baryshnikov G.F. (1981). Sub-genus Panthera Oken, 1816. Genus Panthera.
Abstract: The monograph provides taxonomic description of sub-genus Panthera Oken, 1816, genus Uncia grey, 1854. Snow leopard inhabits the mountains of Tajikistan, the Pamirs, Tien Shan, Tarbagatai, the Altai, the Sayans; also the mountain of Mongolia, Tibet, the Himalayas, and Hindukush, where it keeps to alpine meadows and woodless rocks at up to 3,000 – 4,000 m above sea level in summer, and descends to a lower elevation in winter. It described from the Altai. They are of minor trade importance. This species is rare all over its habitat and included in the Red Data Book of the USSR.

Bannikov A.G. (1971). Genus Panthera.
Abstract: It gives the description of genus Panthera: lion, tiger, leopard, jaguar and snow leopard. The mountains of Central Asia and South Siberia limit the habitat of snow leopard in the USSR. This species is also distributed in the Himalayas, Tibet, and mountains of Mongolia. In summer, it lives at 3,660 3,970 m above sea level, while in winter, following the ungulates; snow leopard descends to 1,800 m. In the Himalayas, it ascends up to 5,500 m above sea level in summer. In Djungar and Talas Ala-Tau, snow leopard keeps at 600 1,200 m. It takes refuge in caves and cracks of rocks. Snow leopard is mostly active in twilights and night, rarer in daylight, and preys on ungulates, hares, marmots, and others. The coupling period is winter or early spring. A gestation is about 90 days. It has 3 5 cubs in a litter.

Bannikov A.G. (1973). Snow leopard (irbis). Felis uncia.
Abstract: Irbis is distributed in highlands of Kazakhstan, Kyrgyzstan, Tajikistan, and Altai. It preys mainly on wild sheep and ibex, marmots, pica, snow-cock, rarer other ungulates, rodents and birds. Sometimes it attacks domestic sheep. At the beginning of spring this species is on heat, gestation period being 90 100 days. Female bears two three (to five) cubs. The litter splits in one year. The animal sheds hair twice a year. It has a low population and therefore hunting for snow leopard is prohibited.
