Aizin B.M. (1969). Siberian ibex Capra sibirica Pall.
Abstract: It describes status of ibex in Kyrgyzstan, its distribution, behavioral patterns, enemies and competitors, etc. The enemies of ibex are snow leopard and wolf. All year round snow leopard preys on ibex its main food object and, therefore, should there be ibexes, snow leopards would be somewhere around. In winter, a considerable number of ibex dies from wolves. Sometimes dogs prey on ibex, too. Golden eagles and bearded vultures prey on young ibexes. However, poachers remain the most dangerous enemy.

Razmakhnin V.E. (1977). Siberian wild ibex.
Abstract: It provides a detailed description of biology, distribution, geographic variability, behavior, and locomotion features of ibex in the USSR. Its population was defined as 100,000 animals, main enemies being wolf, snow leopard, and golden eagle. Wolf mainly preys on ibex at the end of winter; old males, weakened during the heat mostly becoming a prey. Snow leopards prey on ibexes all year round. Golden eagles mostly prey on young ibexes.

Saparbayev, S.K., & Woodward, D. B. (2008). Snow Leopard (Uncia uncia) as an Indicator Species and Increasing Recreation Loads in the Almaty Nature Reserve.
Abstract: The purpose of this research is to analyze the data on ecology, biology and dynamics of snow leopard population in the Almaty Nature Reserve and to identify if the increasing numbers of ecotourists could contribute to the decrease of Uncia uncia population. The results of the study show that increasing recreation loads in the Reserve and adjacent territories elevate the disturbance level to the snow leopard's main prey Siberian Ibex and to the predator itself that could result in a decrease of population of this endangered species or its total extinction.

Sokolov G.A. (2003). Predatory mammals of Central Siberia, status of populations, influence of anthropogenic factors.
Abstract: The species resources of Siberia's fauna decrease from south to north. The highest diversity of species is observed in the mountain systems, the lowest in sub-zones of south and central taiga and steppe zone, where the cat family species are absent. During the last 50 150 years number of species has decreased two- to tenfold. Imperfect hunting management, farming, and mining operations resulted in transformation of the animal habitats. Population of fox, polecat, and sable has reduced; snow leopard and dhole becoming endangered species. If current tendencies continue to develop some species will disappear in the region in decades to come.

Volozheninov N.N. (1986). Ecology of some mammals in western part of the Hissar ridge.
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.

Vorobjov G.G.& Ostastshenko A.N. (2002). The winter distribution of the ibex (Capra sibirica) and wild boar (Sus scrofa) in the Chatkal River Basin.
Abstract: There are 3 independent groups of the ibex in the Chatkal River basin and 2 ones of the wild boar. Therefore the populations of these animals are vulnerable in wintertime. The wild sheep (Ivis …••Œ‹) wide distributed in Chatkal valley earlier has not been found out. Pskem population of ibex is assessed as 30 individuals, Chandalash population as 450 ibexes and Chatkal population is assessed less than 200 individuals. Number of wild boar in Pskem ridge is 200 individuals; total number of Chandalash population is 20-25 boars.

Esipov A.V. (2000). Current state of snow leopard and its main preys in Hissar nature reserve.
Abstract: An expert evaluation of the numbers of snow leopard and its preys, Siberian ibex and long-tailed marmot, was made on the basis of surveys conducted in Hissar nature reserve in 1999. The total number of the snow leopard is estimated at 12-16 individuals, whereas that of the Siberian ibex at 1000 individuals. An average density of the population of the long tailed marmot ranges at 4,8 individuals per ha. The ratio of the numbers between the snow leopard, Siberian ibex and long tailed marmot is 1:68:450. The major threats for the snow leopard are poaching on the borders of the nature reserve, a decrease in of preys, shrinking of the range in areas adjoining the nature reserve as a result of intensification of industrial activities and disturbing factors. For the Siberian ibex and long tailed marmot the major limiting factors are the shrinking of the areas and deterioration of the forage value of the high-mountain pastures, as well as the direct competition for forage with domestic animals at the sites adjoining the territory of the nature, as well as disturbing factors.
