Kolosov A.M. (1979). Genus Snow leopards Uncia.
Abstract: It provides description of appearance, distribution, behavioral patterns, and use of snow leopard in the USSR. The predator inhabits the mountains of Central Asia, east of the Amudarya river, along the ridges of Djungar Ala-Tau and Tarbagatai, South Altai, West and East Sayans. Its main food is ungulates, though it also preys on snow-cocks, marmots, small birds, and rodents. Sometimes attacks sheep. It has no enemy other than wolf; its diseases are not studied. Snow leopard is not dangerous for man. The fur-skin is used for making rugs and fur. Less than 1,000 animals are hunted globally. Before 1960, in the USSR less than 120 skins were annually purchased. Its total population is several thousand animals.

Heiz A.V. (1979). Some legal issues of snow leopard protection in the USSR.
Abstract: Any commercial use or sport hunting for snow leopard is prohibited everywhere. In the USSR, illegal hunting or attempt to hunt was prosecuted according to the criminal or administrative law. The following additional measures are required to successfully protect the species: conducting awareness activity in local communities, continuous control, quick investigating of snow leopard extermination cases, and regular counts of snow leopard population.

Kolosov A.M. (1961). Snow leopard, or irbis, – Felis uncia Schreb.
Abstract: It describes appearance, distribution and behavioral patterns of snow leopard in the USSR. The predator inhabits the mountains of Kyrgyzstan, Kazakhstan, Tajikistan, and the Altai and mainly feeds upon ungulates, and also snow-cocks, marmots, small birds, and rodents. Sometimes attacks sheep. Number of snow leopards is very low.

Kaletskiy A.A. (1974). May-“traven”.
Abstract: Diverse flora and fauna and seasonal phenomena in nature are stated in a popular form. Snow leopard is noticed to be a rare species, its population being significantly influenced by catching for zoos: over 400 snow leopards have been caught for this purpose over the last 35 years.

Kaletskiy A. (1978). They must live (Vol. N 11.).
Abstract: Among large predators included in the Red Data Book of the USSR and Red List of IUCN the author describes snow leopard. A population of snow leopard in the USSR is estimated to be 500 animals, and no more than 1,000 in the world. In the past, irbis was believed to be a harmful animal and hunting for this species was encouraged. Today, population of the predator is reducing because of poaching and decreasing number of species it preys on such as ibex, wild sheep, wild boar, and marmots. The situation is exacerbated by biological features of this species first of all its slow rate of reproduction. It is concluded that snow leopard needs urgent protection measures since the species is on the verge of disappearance.

Ishunin G.I. (1989). The Felids family Felidae Gray, 1821.
Abstract: Zoolites of the Felidae family are known from the Upper Eocene Lower Pliocene in Eurasia, Africa, and North America. Two sub-families are know to inhabit the territory of the USSR and adjacent territories: the extinct sabre-toothed Felidae species Machairodontia and now existing Felidae species. In the USSR the extinct Felidae species were found to exist in Upper Miocene, Upper and Middle Pliocene, and Pleistocene. In Eurasia panthers has been know since early Pliocene. Three species were found in Uzbekistan – the extinct cave lion Felidae sd†l…†… (Goldfuss, 1810), and now existing P…nth†a… tigris, P…nth†a… pardus. The ancient finds and modern habitats are briefly described. Genus Uncia is represented by one species snow leopard or irbis. Probably it appeared in later Pliocene or Pleistocene in the mountain of Central Asia. In Uzbekistan, remains of snow leopard were found in the Samarqand region in the layer of Upper Pleistocene or Holocene. Probably it moved into the area in Pleistocene or the period of glacier removal in the Western Tien Shan mountains, Turkestan, Zeravshan, and Hissar ridges.
