Mallon, D. P. (1991). Status and Conservation of Large Mammals in Ladakh. Biological Conservation, 56(1), 101–119.
Abstract: The distribution and status of large mammals was surveyed in a 15 000 km2 study area in Ladakh, India. Snow leopard Panthera uncia, wolf Canis lupus, ibex Capra ibex and bharal Pseudois nayaur have an almost continuous distribution throughout; Ladakh urial Ovis vignei, Tibetan argali Ovis ammon, wild ass Equus kiang and brown bear Ursus arctos have a limited distribution. Snow leopard prefer lower altitudes and rocky, undisturbed areas. Ibex and bharal occupy similar rocky habitats but their ranges are mostly separate, with a small area of overlap. The Ladakh urial shows signs of recovery from an earlier decline. Natural resources are widely used for fuel, fodder and grazing, but favourable factors include a low human population, low level of hunting and the existence of some uninhabited and undisturbed areas. A comprehensive Protected Area Network has been proposed.

Johnston, L. A., Donoghue, A. M., O'Brien, S. J., & Wildt, D. E. (1991). Rescue and maturation in vitro of follicular oocytes collected from nondomestic felid species. Biol Reprod, 45(6), 898–906.
Abstract: The potential for rescuing immature oocytes from the ovaries of females of rare felid species which die or undergo medical ovariohysterectomy was evaluated. Ovaries were recovered from 13 species representing 35 individuals in good-to-poor health. Although the majority of females were 10 yr of age or older and in fair-to-poor health, a total of 846 oocytes were recovered of which 608 (71.9%) were classified as fair-to- excellent quality. One hundred of these oocytes were used for initial maturation classification and as parthogenetic controls. Overall, of the 508 fair-to-excellent quality oocytes placed in culture, 164 (32.3%) matured to metaphase II in vitro. For species in which 3 or more individuals yielded oocytes, mean oocyte maturation rates were as follows: 36.2%, tiger; 27.9% leopard; and 8.3%, cheetah. In vitro insemination of oocytes resulted in fertilization (2 polar bodies, 2 pronuclei, or cleavage) rates of 9.1% to 28.6% (leopard) using homologous fresh spermatozoa and 4.0% (lion) to 40.0% (puma) using homologous frozen-thawed spermatozoa. Inseminations using heterologous (domestic cat) spermatozoa also resulted in fertilized oocytes in the tiger, leopard, snow leopard, puma, serval, and Geoffroy's cat (range in fertilization rate, 5.0% for leopard to 46.2% for puma). Cleaved embryos resulted from the insemination of leopard oocytes with homologous sperm (n = 1 embryo) and puma oocytes with domestic cat sperm (n = 3 embryos). These results demonstrate that immature ovarian oocytes from rare felid species can be stimulated to mature in vitro despite an excision-to-culture interval as long as 36 h.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: Irbis is a very endangered species in Uzbekistan. The article provides a brief description of the snow leopard appearance and distribution. Reasons for reduction of snow leopard population is reduction of ungulate populations it preys on ibex and wild sheep and anthropogenic disturbance. Hunting for snow leopard is prohibited everywhere.

Zhou, S. (1991). On “uncia uncia” and “meng ji” in Shan Hai Jin (Vol. 13).
Abstract: Meng ji is described in Shan Hui Jin (Classic of Mountains and Rivers) as a leopard-like animal adept in hiding with white fur and a patterned forehead. This article makes a comparison between “meng ji” and “uncia uncia” in terms of their shapes, fur colors, natural environments of habitats, habits, characteristics and native areas, and comes to the conclusion that “meng ji” is what we call “uncia uncia” nowadays. The description of “meng ji” in Shan Hui Jin should be the first record of Uncia uncia in the world.

Abstract: Snow leopard is a rare species with shrinking habitat and decreasing population (category III). It is distributed in Tien Shan (the ridges of Karjantau, Ugam, Talas, Kyrgyz, Zailiyskiy, Kunghey, Terskey, Ketmen), Djungar Alatau, Tarbagatai, Saur, and South Altai. This species has disappeared in the Syrdarya Karatau and the mountains of North Tien Shan. Its total number in Kazakhstan is estimated to be 180-200 animals. The threats are reduction of mountain ungulates and poaching. Snow leopard is protected in the Aksu-Djabagly, Alma-Ata, and Markakol nature reserves and the Alma-Ata, Lepsin, and Tokhta sanctuaries. The Djungar nature reserve needs to be established.

Abstract: It provides field signs and brief comparative characteristic of cat species in Uzbekistan, five of which are included in the Red Data Book of Uzbekistan and the USSR: lynx, caracal, manul, snow leopard and cheetah. Snow leopard is protected in the Zaamin, Chatkal, and Gissar nature reserves. A snow leopard female bears up to five cubs (normally two three) once in two years. Gestation period is 90 days. Female suckles her cubs until they reach the age of three four months.
