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.

Lanier, D. L., & Dewsbury, D. A. (1976). A quantitative study of copulatory behaviour of large Felidae. Behavioural-Processes, 1(4), 327–333.
Abstract: Observed a total of 109 copulations in 6 male-female pairs from 4 species of large Felidae. The mean intromission durations were 3.0 sec for Asian leopards (Panthera pardus), 3.3 sec for African leopards (P. pardus), 12.9 sec for snow leopards (Uncia uncia), 2.3 sec for spotted jaguars (P. onca), 3.3 sec for black jaguars (P. onca), and 12.4 sec for Siberian tigers (P. tigris). Behavioral patterns were qualitatively similar across species; all displayed a copulatory pattern with no lock, no intravaginal thrusting, ejaculation on a single insertion, and multiple ejaculations. Whereas domestic cats are reported to assume a neck grip and to tread prior to insertion, these larger Felidae generally did so after intromission had been achieved. After copulation, females of some pairs swiped at the male and displayed a rolling after-reaction. (18 ref) (PsycINFO Database Record (c) 2000 APA, all rights reserved)(unassigned)

Sapozhnikov G.N. (1976). Wild sheep in Tajikistan.
Abstract: The monograph provides data concerning taxonomy, morphology, and age variability of wild sheep. There described distribution, number, population composition, behavioral patterns, reproduction, predators and parasites. Besides, a matter of conservation and sustainable use of the species is discussed. Together with wolf, snow leopard is called an enemy of O. o. vignei and argali (O. o. polii).

Zakhidov T.Z.Meklenburtsev R.N., B. O. P. (1971). Snow leopard Uncia uncia Schreb. Distribution of fauna elements over Central Asia (Vol. Vol. 2. Vertebrate animals.).
Abstract: Snow leopard inhabits the mountainous ecosystems from Tarbagatai to Hissar and Pamir. It feeds upon large animals such as ibex, argali, roe deer, and sometimes domestic sheep, rodents, and birds (most frequently snow cock). The skin of this animal is not of significant value and is rarely an item of trade. In many countries, zoos will readily buy snow leopards. There is no danger for a man to catch snow leopard since even being wounded during a hunt, the animal would never attack the man. An encounter with snow leopard in the mountains will always end safely for human being, as it is always first to spot a man and go away unnoticed.
