Marma, B. B., Yunchis, V.V. (1969). Biology of the snow leopard (Panthera uncia uncia). Zoologicheskii Zhurnal, 47(11), 1689–1694.
Abstract: The methods to obtain 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 Sumatran tigers. A series of internal, external and clinical indices is established. The rut 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 ghardens of the world abuot 29 snow-leopards were born. 14 of them -- in the Kauna zoological garden.

Gvozdetskiy N.A. (1970). Altitudal landscape zones.
Abstract: It provides geobotanic and zoogeographic description of vertical landscape zoning. Particularly, in alpine meadows and meadow steppes and partially zone of mountain plateau (“syrt”) of highland, the common species are argali (Ovis ammon poloi), ibex (Capra sibirica sakeen), snow leopard (Felis uncia), Tien Shan bear (Ursus arctos leuconyx), and red pica; very numerous are marmots and vole (Microtus gregalis). The bird fauna includes Himalayan snow-cock (Tetraogallus himalayensis), Alpine chough (Pyrrhocorax graculus), chough (P. pyrrhocorax), horned lark (Eremophila alpestris), rosefinch species. There are many waterfowl birds on the lakes. There are many Central Asian, particularly Tibetan species among the animals inhabiting highlands of the Tien Shan.

Kydyraliev A.K. (1970). Some animal species' habitat alteration in the Central Tien Shan (Vol. Part 1.).
Abstract: Irrigation and drainage activity in Tien Shan led some bird species to disappear. Number of species to build their nests in tree holes has dropped. Mongolian sandpiper and black-bellied sand grouse disappeared in the steppe areas. Great bustard, formerly nesting in this area, can now be rarely seen only in migration. The direct anthropogenic influence resulted in shrinkage of game animal and bird populations such as moral, goitered gazelle, argali, snow leopard, and stone marten.

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.
