Abstract: The work contains data on biology snow leopard in Hissar nature reserve, Uzbekistan. The number of snow leopards in this reserve has increased from two or four in 1981 to between 13 and 17 individuals in 1994. Since 1981, snow leopards have been sighted 72 times and their tracks or pugmarks 223 times. In the Hissar Nature Reserve snow leopards largely feed on ibex. Over a period of 14 years, 92 kills and remains of ibex aged from one to thirteen years of age have been examined. Other records of predation, by the number of events observed, include 33 cases of juvenile and mature horses, 25 long-tailed marmot (Marmota caudata). 18 Himalayan snowcock (Tetraogallus himalayemis), 17 domestic goat, 13 wild boar (Sus scrofa), five domestic sheep and three incidents involving cattle. Twenty-two attacks on domestic flocks were reported, and these occurred during both the daytime and at night. Snow leopards usually mate between the 20th of February and March 20th. The offspring are born in late April to May, and there are usually two per litter (23 encounters), although a single litter of three has also been recorded.

Abstract: The marchor habitat in Tajikistan is fragmented. The animals are reproduced in enclosures of the Ramit nature reserve and released into wildlife in Khel canyon. Two females were killed by snow leopard.

Abstract: It provides general information about the Hissar nature reserve (Uzbekistan), its physico-geographical features and description of flora and fauna. The following predator species inhabit the nature reserve: wolf, fox, Tien Shan brown bear (four five animals per 100 sq. km), ermine, weasel, stone marten, otter, badger, lynx (two animals per 100 sq. km) and snow leopard (about 10 animals). Wild boar and ibex are common species for the area (22 25 animals per 100 sq. km).

Abstract: It describes genus and species features of snow leopard such as appearance, skull, sizes, phylogenetic links, distribution, geographic variability, biology including number, habitat, refuges, activity in daylight and night, behavioral patterns, reproduction, enemies and rivals, and practical use of the species.

Abstract: Snow leopard is rare and extinctive species that have scientific and aesthetic significance. The features of genus Uncia and species Uncia uncia are described. Also distribution, habitat, way of life, reproduction biology, behavioural patterns, migration routes, infections and parasites, enemies and competitors, number and number fluctuation, practical value of snow leopard in the Kazakhstan are given.
