Yazan Yu.P. (1980). The Almaty state nature reserve.
Abstract: History of the Alma-Ata nature reserve establishment, its location physical and geographic data, climate, and vegetation zones are described. Fauna of the protected area is represented by 64 mammal species, and about 200 bird species. Briefly described are behavioural patterns of roe deer, moral, wild boar, Siberian ibex, snow leopard, lynx, brown bear, and marten, and other mammals of the mountainous area.

Golub O.N. (1981). The Ramit nature reserve and its problems.
Abstract: The following Red Data Book species inhabit the Ramit nature reserve: snow leopard, bear, lynx, otter, Bukhara deer, etc. Its population is indicated to be closely related to number of ibex (150 animals). The latter is subject to heavy anthropogenic pressure when migrating outside the nature reserve in winter.

Abstract: Tyzzer's disease was diagnosed histologically in 2 litters of newborn snow leopard kittens. The gross and histological lesions were similar to those reported in domestic cats and other animals. No signs of illness was noted in either of the snow leopard dams.

Abstract: It provides general information about the Kyrgyz state nature park ®Ala-Archa", its physico-geographical features, relief, landscape zoning, and description of flora and fauna. Snow leopard, Tien-Shan brown bear, ibex (more than 300 animals), porcupine, stone marten, ermine, and marmot, etc. are mentioned as the most interesting animals.

Abstract: The area of the Chatkal nature reserve reduced as part of its territory (a land plot in the Shavasay river basin) was assigned to a military game preserve. As regime of protection worsened, number of animals such as Menzbier's marmot, snow leopard, ibex, snow cock, and black stork began to reduce.

Abstract: In a popular form, it says about wildlife of Pamir, unique animal kingdom of highlands. The author describes his personal encounter with snow leopard following a herd of ibex and thinks of peculiarities of this large predator and reasons for hunting it.

Afanasiev Y.G. (1988). The Karatau nature reserve.
Abstract: The Karatau ridge is an extreme north-west spur of the Tien Shan mountain system. Flora of Karatau is represented by no less than 1,500 higher vessel plant species. Karatau and the adjacent areas host 16 reptile species, 114 bird and 42 mammal species. Snow leopard disappeared from fauna of Karatau in 20th century. In 1940-s, the animal species was met at the highest point of the ridge in the Manjilki area, particularly in tract Kor-Djailau. Now there are no snow leopards in the area under study a fact evidenced by local hunters and shepherds.

Meiers, S. T. (1992). Habitat use by captive puma (Felis concolor) and snow leopards (Pathera uncia) at the Lincoln Park Zoo, Chicago, Illinois. Ph.D. thesis, DePaul University, .
Abstract: Between May 1990 and January 1991, behavioral observations were made of two captive pumas (Felis concolor Linnaeus), and two captive snow leopards (Panthera uncia Schreber) in their outdoor exhibits at the Lincoln Park Zoological Gardens, Chicago, Illinois. Behaviors compared within and between species included: 1) time spend in the different habitat types; 2) time budgets for the different behaviors: laying, moving, sitting, standing, crouching, in the tree, drinking, urinating, defecating, within their inside dens, and “behavior not determined” when the identity or behavior of the individuals could not be determined; and 3) mobility of the animals within their exhibits. Also examined were: 4) preferences for different habitat types; 5) recommendations for future exhibit designs. Both species located themselves within their exhibits in a non-random manner. The majority of cats' time was spent in elevated locations (i.e., gunite ledges approximately 1-5.5 m above ground-level). Snow leopards exhibited this tendency to a greater extent than did the pumas. Both species also spent the majority of their time in the lying-down behavior; again snow leopards displayed this tendency significantly more than the pumas. Pumas were highly mobile and changed locations and behaviors in their exhibit significantly more than the snow leopards. No significant differences were noted between conspecifics in regard to habitat type preference, or mobility within the exhibit. Suggestions for future exhibit design include elevated locations for the cats to lay and look around within and outside their exhibits, caves for access to shade or relief from inclement weather, and ground surfaces to move about on. Features for exhibit design should take into consideration the natural habitat of the cat to occupy the exhibit.

Schmidt, A. M., Hess, D. L., Schmidt, M. J., & Lewis, C. R. (1993). Serum concentrations of oestradiol and progesterone and frequency of sexual behaviour during the normal oestrous cycle in the snow leopard (Panthera uncia). J Reprod Fertil, 98(1), 91–95.
Abstract: Serum oestradiol and progesterone concentrations were measured at weekly intervals for six months, and correlated with daily behavioural observations in two adult female snow leopards (Panthera uncia). Three oestradiol peaks (> 21 pg ml-1; interval 3.6 weeks) were identified in a snow leopardess housed alone (two more were probably missed because of the weekly sampling schedule), and three oestradiol peaks were identified in a snow leopardess housed with a male as a breeding pair (interval 6 weeks). Daily frequencies of feline reproductive behaviour averaged 1.77 observations per observation period during weeks of high oestradiol and 0.62 during weeks of low oestradiol. Progesterone concentrations did not rise above baseline values (< 2 ng ml-1) in the isolated animal, but 6 weeks of high progesterone concentrations (4.9- 38.8 ng ml-1) was recorded in the paired snow leopardess following mating. No offspring were produced. Snow leopards were observed daily for an additional 4.5 years. Sexual behaviour peaks could be clearly identified from December through April, and average daily sexual behaviour scores were higher during these months than during the rest of the year. Intervals between sexual behaviour peaks for the isolated snow leopardess averaged 3.03 weeks. The sexual behaviour of the paired snow leopards decreased for 8-9 weeks following mating when no offspring were produced, and decreased for 13 weeks in one year when a single cub was born.
