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.

Abstract: The snow leopard has remained little studied in the past, and most of the information available is either in the form of natural history or anecdotal notes. The inaccessibility of the terrain and its secretive habits make this one of the more difficult animals to study in the wild. In the past decade, several ecological surveys were conducted in India, Nepal, China and Mongolia, which gave us information on the status and distribution of snow leopard (Jackson, Mallon, Fox, Schaller, Chundawat) A detailed study in Nepal through light on its secretive habits ( Jackson and Ahlborn, 1989). Even then little is known about its feeding habits. The present paper discusses this aspect from a study which was part of a detailed study conducted on the ecology of snow leopard in India from October 1987 to Feburary 1990.

Abstract: A total of 206 individual Blue sheep Pseudois nayaur were estimated in Barse and Phagune blocks of Dhorpatan Hunting Reserve (DHR) and population density was 1.8 Blue sheep/sq.km. There was not significant change in population density from last 4 decades. An average 7 animals/herd (SD-5.5) were classified from twenty nine herds, sheep per herds varying from 1 to 37. Blue sheep has classified into sex ratio on an average 75 male/100females was recorded in study area. The sex ratio was slightly lower but not significantly different from the previous study. Population of Blue sheep was seen stable or not decrease even there was high poaching pressure, the reason may be reducing the number of predators by poison and poaching which has
supported to increase blue sheep population. Because of reducing the predators Wolf Canis lupus, Wild boar population was increasing drastically in high rate and we can observed wild boar above the tree line of DHR. The frequency of occurrence of different prey species in scats of different predators shows that, excluding zero values, the frequencies of different prey species were no significantly different (ö2= 10.3, df = 49, p > 0.05). Most of the scats samples (74%) of Snow leopard, Wolf, Common Leopard, Red fox's cover one prey species while two and three species were present in 18% and 8%, respectively. Barking deer Muntiacus muntjak was the most frequent (18%) of total diet composition of common leopards. Pika Ochotona roylei was the most frequent (28%), and Blue sheep was in second position for diet of snow leopards which cover 21% of total diet composition. 13% of diet covered non-food item such as soil, stones, and vegetable. Pika was most frequent on Wolf and Red fox diet which covered 32% and 30% respectively. There was good positive relationship between the scat density and Blue sheep consumption rate, increasing the scat density, increasing the Blue sheep consumption rate. Blue sheep preference by different predators such as Snow leopard, Common leopard, Wolf and Red fox were 20%, 6%, 13% and 2% of total prey species respectively.

Abstract: The Disappearance of traditional ungulate prey of the snow leopard may be contributing to its endangered status in the wild. Soviet biologists have noted that wild sheep are a primary prey of the snow leopard in the southern Russian union republic and the Central Asian union republic of the U.S.S.R. While poaching appears to have had some impact on the status of these sheep, econmic pressures may be contributing to their decrease. Evidence presented for KAzakhstan and three regions of the Russian republic demonstrates that commercial sheep and goat production appears to be growing at a very high pace in these areas, thus consumming habitat otherwise available for wild herds.

Abstract: Additional data on Lepus tolai, Ochotona rutila, Citellus relictus, Marmota caudata, Sus scrofa, Capra sibirica in western part of the Hissar ridge, Uzbekistan, is given here based on materials of the years 1978-1983. Information about distribution of these species, their numbers, food, enemies, and other ecologic issues is provided. Capra sibirica is a principle species snow leopard preys on. In 1899 1983, the authors recorded more than 20 cases of snow leopards' killing ibex of different ages.

Abstract: The author studied livestock killed by predators in the Spiti Valley, India, to determine what species had killed yaks, horses, donkeys, and other domestic animals. Eleven of the kills examined were made by snow leopards and six by the Tibetan wolf. Wolves were involved in surplus killings, while snow leopards kill as food is needed. lgh
