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.

Ishunin G.I. (1964). Cats.
Abstract: It provides information about the cat family species in Uzbekistan (steppe cat Felis libyca, reed cat Felis chaus, Turkistan lynx Felis lynx isabellina, manul Felis manul, sand cat Felis margarita, Turan tiger Felis tigris virgata, Middle Asia leopard Felis pardus tullianus, and snow leopard Felis uncia. Snow leopard is distributed over the Hissar ridge, and the mountains of Kuydytavak, Khoddjachilimakhram, Zardalyupaz, Khodjapiriyah and Belata. Trade significance of snow leopard is negligent. In the Sary-Asia district one skin was traded in 1934 and 1935, three in 1936, four in 1937, one in 1946, and two in 1947.

Koshkarev E. (1998). Critical Ranges as Centres of Biodiversity (Vol. N 14).
Abstract: A high percentage of rare species in Central Asia experience limited conditions for distribution. Geographic centers with higher species diversity are generally constrained in terms of territory: they are formed when ranges overlap. But in Central Asia and along its borders with Russia, centers of biodiversity overlap at the very marginal edges of ranges. Central Asian species cross into Russian territory, where desert and steppe are replaced by thick forest. Here the northern borders of their ranges are sharply fragmented and isolated. Typical examples for Central Asia are the ranges of the cheetah (Acinonyx jubatus), Asian leopard (Panthera pardus caucasica), striped hyena (Hyaena hyaena), Bukhara deer (Census elaphus bactrianus), markhor (Capra falconeri), blue sheep (Pseudois nayauf) and argali (Ovis ammon). In Russia are the Altai subspecies of argali, the Siberian argali (O.a.ammon), the mountain goat (Capra sibirica), Mongolian gazelle (Procapra gutturosa), snow leopard (Uncia uncia), Pallas' cat (Felis manul), dhole (Cuon alpinus), grey marmot (Marmota baibacina), Mongolian marmot (M. sibirica) and tolai hare (Lepus tolai). Where the numbers o f individuals has fallen to extreme lows, the most effective mechanism for species survival may be supporting the integrity of ranges, in order to preserve population exchanges between neighboring groups. The geographic location of reserves and other protected territories is vitally important for the survival of Central Asian species, given the acute fragmentation of their ranges. These reserves should include significant, viable centers of population the key places. Wherever the creation of permanent protected territories is impossible, a new tactic must be found, such as introducing temporary limitations on the use of land for agriculture and hunting. But all protected territories, whether temporary or permanent, should be connected, forming a core and periphery. The marginal range areas must not be forgotten, if total protection of endangered populations is to be accomplished.

Abstract: The stability of animal populations in respect of the influence of the environment is well known to be conditioned by their location in the natural habitat and their ability to establish new territories. In the peripheral regions of natural habitat, however-in the zone that is ecologically least favourable-the situation of the animal is most unstable. This is due to increased pressure of environmental factors which favour neither a high frequency of contacts between individuals belonging to sperate populations nor an increase in the number of such contatcs and their stabilization. In our opinion, this describes the situation that has come about in certain regions inhabited by the snow leopard in the Soviet Union.

Zhiryakov V.A. (1979). The influence of large predators on wild mammal populations in the Almaty nature reserve.
Abstract: There are following large predators in the Almaty nature reserve: wolf (5-6), snow leopard (single occasions), Turkistan lynx (single occasions), and Tien Shan brown bear (15-20). The share of wild mammals (roe-deer, ibex, wild boar, argali, gazelle, moral, and badger) being eaten by predators is 18.2 percent, about 60 percent of the entire prey falling to the share of wolf.

Abstract: Due to development of new lands and increased anthropogenic pressure animals are displaced from their habitats. Intense poaching caused dying away a number of animals such as Turan tiger, moral, and kulan in Uzbekistan at the end of 19th beginning of 20th century. The endangered species are marchor, cheetah, lynx, snow leopard, caracal, and cobra. Species put on the verge of a total extermination are included in the national Red Data Book (22 mammal species, 31 bird species, five reptile and five fish species). The introduction of some species such as raccoon, European fallow deer, nylghau, and chinchilla was unsuccessful.

Abstract: The data on the species composition, numbers and distribution of the terrestrial vertebrates over territory Hissar nature reserve are discussed. About 60 species of amphibians, reptiles and mammals have been recorded in the reserve as a result of our own researches and the analyses of communication. There were recorded 5-7 individuals of snow leopard in Kyzylsu site of nature reserve and 15 individuals in Miraki site of nature reserve in 1979-1981.
