Ognev S.I. (1935). Uncia uncia Sch., 1778. Irbis or snow leopard (Vol. Vol.3.).
Abstract: It describes identification signs and taxonomy of genus Uncia Gray and the only representative of genus Uncia uncia Sch., 1778, distribution and some features of the species' biology. A habitat of snow leopard includes the mountains of Central Asia from Kopet-Dag and northern Iran to the east along the mountain systems of Pamir, Turkestan, Gilgit, Tibet, Himalayas before the country Kam. On the north, snow leopard is met in Tarbagatai, Altai, Sayans, and further eastward to the Yablonoviy and Stanovoy ridges reaching the confluence of the Shilka and Argun rivers.

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.

Wahlberg, C., Tarkkanen, A., & Blomqvist, L. (1982). Further observations on the multiple ocular coloboma (MOC) in the snow leopard, Panthers uncia. In L. Blomqvist (Ed.), International Pedigree Book of Snow Leopards (Vol. 3, pp. 139–144). Helsinki: Helsinki Zoo.
Abstract: The first observation of the occurrence of multiple ocular coloboma (MOC) in a snow leopard was reported in the International Pedigree Book of Snow Leopards Volume I in 1978 (1). The lesions in this syndrome consist of coloboma of the upper eye lid and uveal coloboma of the globe. Even colobomatous retinal cysts and retinal dysplasia have been noted. The ethiology of in all ten cases of MOC in the snow leopards kept at the Helsinki Zoo were described and discussed in detail in Volume II of the International Pedigree Book of Snow Leopards (2,3). Three cases of MOC in the snow leopards kept at Henry Doorly Zoo, Omaha, Ne., have been described by Phillips (4), one case is known of in Amsterdam (van Bree, personal communication), and two cases in Zoo Zurich (Isenbugel and Weilenmann, pers. comm.) The ethiology of the defect is still not known although various theories ranging from genetic to exogenous factors have been presented.

Abdusalamov I.A. (2001). Required protection measures for rare and endangered vertebrate species in Tajikistan (Vol. N 2 (143)).
Abstract: The network of Tajikistan's protected areas (four nature reserves, 14 national and 18 regional sanctuaries, one national park) is described. The establishment of `Shakhristan state complex nature reserve' and `Sarykamish state complex reserve', and interstate nature complex park on northern slope of the Turkestan ridge is recommended to improve conservation practices for a number of endangered vertebrate animal species in Northern Tajikistan (such as brown bear, snow leopard, wild sheep, and others).

Freeman, H. (1983). Behavior in adult pairs of captive snow leopards (Panthera uncia). Zoo Biology, 2(1), 1–22.
Abstract: Eight adult pairs of snow leopards (Panthera uncia) were observed for one to three years in the months December through March to determine the species' social and reproductive characteristics in captivity. To statistically examine the occurrence of behaviors as a function of estrus, the observation weeks were divided into three time blocks: before estrus, estrus, and after estrus. Using percentage of scan samples as an estimate of time spent in various behaviors, 16 behaviors and combined behavior categories were examined for (1) behaviors that differentiated successfully from unsuccessfully breeding pairs, (2) sex differences in behavior, (3) significant correlations between pair members, and (4) behaviors that showed time block effects. The rationale for identifying a behavioral profile of successful breeders in snow leopards was to aid zoos in their captive management programs by increasing their knowledge of the social behavior of this species. By finding correlates to breeding success, informed decisions on whether to change partners after a certain period of time, how to group the cats, and the optimum strategy for a survival plan can be made.

Kashkarov D.N. (1923). Living conditions and living in various parts of the mountainous Turkestan. Central Asian snow leopard, irbis (Vol. Issue 2. The animals of mountainous Turkistan.).
Abstract: It describes fauna of the mountainous Turkestan. Irbis is met in Tien Shan, Pamir, Bukhara and Kopet-Dag. Apart from Turkistan, it lives in the Altai, Tibet and on northern slopes of the Himalayas. In Kopet-Dag, this species is met with another panther Caucasian leopard. It preys on ibex, wild sheep, roe deer, keklik (partridge), snow-cock and porcupine. It also attacks small livestock. Normally this species would never attack the man though hunters mentioned some cases that evidence otherwise.
