Ale, S., & Brown, J. (2007). The contingencies of group size and vigilance (Vol. 9).
Abstract: Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect.
Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance.
Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour?
Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group.
Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size.

Pokrovskiy V.S. (1976). Snow leopard, or irbis.
Abstract: It considers biology of snow leopard, provides data concerning its number and distribution, and shows environment correlation of the predator. Besides, it describes the ways of catching snow leopards, and conditions under which it can be kept in enclosures. Precise recommendations for the species protection are given.

Sapojnikov G.N. (1984). Distribution and number of several endangered mammals and birds of Tajikistan.
Abstract: Many years' data connected with the distribution and number of endangered species of animals as dhole (Cuon alpinus Pall), striped hyena (Hyaena hyaena L.), snow leopard (Uncia uncia Shreb.) and birds of Tajikistan are given. Area of snow leopard includes the most of mountain ridges in this country. The total number is evaluated about 160-200 individuals. The record quantity of legal harvested skins of snow leopard is 64 in 1946.

Sokolov V.E. (1986). Snow leopard.
Abstract: Snow leopard is an endangered species. Its number is steadily decreasing. In the USSR, snow leopard is distributed in the mountains of Central Asia: Pamir, Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur. It is also met at altitudes ranging from 1,800 3,500 m above sea level. A total number of snow leopard in the USSR does not exceed 1,000 animals; according to other data 2,000 animals. A decreasing number of snow leopard and its habitat shrinkage is directly related to human's pursuing snow leopards (in the USSR snow leopard was for a long time being considered as a species causing damage to livestock so authorities gave premiums for catching/shooting snow leopards) and reduction of ungulate population. Snow leopards are now protected in mountain nature reserves of the USSR: Chatkal, Aksu-Djabagly, Ramit, Besh-Aral, Sary-Chelek, and Alma-Ata.

Sokov A.I. (1986). Environmental prerequisites for protection and sustainable use of predatory mammals in Tajikistan (Vol. Vol. 3.).
Abstract: In Tajikistan it is necessary to preserve big predators listed in the Red Book, such as Uncia uncia, Ursus arctos isabellinus, Hyaena hyaena, Felis lynx isabellina, Panthera pardus ciscaucasica. An anthropogenic influence has resulted in the species' habitat shrinkage, deficit of food, disturbance of trophic interactions. It is necessary to restore a tiger population in the Tigrovaya Balka nature reserve, and resolve the issue of protection and sustainable use of commercial predatory species.

Yanushevich A.I. (1972). Mammals of Kyrgyzstan.
Abstract: A description of snow leopard, its taxonomy, distribution, habitat, number, behavior, food, reproduction, parasites, infections, and practical importance is given. In Kyrgyzstan, irbis was found in the Chatkal, Kyrgyz, Talas ridges, and Terskei Alatoo. An official annual snow leopard hunting rate ranged from 10 (1955) to 54 skins (in 1936) in 1930-s through 1950-s. 17 snow leopards were caught for the purpose of zoo-export only in 1965-1966. Its skin has no special value and is used by local people for decoration of dwellings and making collars.
