Kazensky, C. A., Munson, L., & Seal, U. S. (1998). The effects of melengestrol acetate on the ovaries of captive wild felids. Journal-of-Zoo-and-Wildlife-Medicine, 29(1), 1–5.
Abstract: Melengestrol acetate (MGA) is the most widely used contraceptive in zoo felids, but the mechanism of contraception and the pathologic effects have not been investigated. For this study, the effects of MGA on folliculogenesis were assessed, and the association of MGA with ovarian lesions was evaluated. Comparisons were made among the histopathologic findings in the ovaries from 88 captive wild felids (representing 15 species) divided into three groups: 37 currently contracepted with MGA, eight previously exposed to MGA, and 43 never contracepted. Ninety-one percent of the felids evaluated had tertiary follicles, and no differences were noted between contracepted and uncontracepted cats. Some MGA-contracepted cats also had corpora lutea indicating recent ovulation. These results indicate that folliculogenesis is not suppressed by current doses of MGA and ovulation occurred in some cats. Therefore, the contraceptive actions of MGA do not occur by suppressing folliculogenesis, and MGA-contracepted felids likely have endogenous estrogens that may confound progestin effects on the uterus. Cystic rete ovarii was the most common pathologic finding, but they were not more prevalent in MGA-contracepted cats. These findings indicate that MGA is not associated with ovarian disease, including ovarian cancer, in contrast to the uterine lesions noted in MGA-treated cats.

Matyushkin, E. N. (2000). Tracks and tracking techniques in studies of large carnivorous mammals. Zoologichesky Zhurnal, 79((4)), 412–429.
Abstract: In Russia, traditions of track observations and the use of tracking techniques in studying the ecology and behavior of mammals were founded by A.N. Formozov. An analytic review of his data on large carnivorous mammals (tiger, snow leopard, wolf, brown bear, wolverine, and others) is given. A special detailed observation of animals' tracks as a source of information on their life is shown only to start. The efficiency of track observations in various fields of studies, including counting animals, is estimated. The values of day and night distances for various animal species, given in literature, have never been properly substantiated methodically. The tracking method is the most effective in studying the use of the home range by animals, drawing the network of their movements and scent-marking behavior. The hunting behavior of large predators in dense forests is can only be deduced by observing their tracks. In some cases, the use of tracking has a distinct advantage over radio tracking. The main propositions are illustrated by the materials of the author obtained in various Russian regions (in forests of the northern Russian Plain and southern Far east) for 1958-1998.

Abstract: A hunt for snow leopard in Kyrgyzstan is described in a popular way. The hunters, people of the Issyk-Kul, caught alive five mature snow leopards by means of traps for less than 1.5 month. Such a quantity within such a minimal period of time is a record, since a total number of snow leopards caught per year is no more than 112 animals. All the animals were safely delivered to the Moscow “ZooCenter”.

Abstract: In Kyrgyz SSR, there are 26 fur animal species, including three acclimatized, six wild ungulate and 70 bird species. They all can serve as objects of commercial and sport hunting. 56 snow leopards, 120 wild boars, 96 roe-deers, 121 ibexes, and 14 argalis were caught 1962 1967. A majority of the animals were exported from the country. The Kyrgyz SSR is one of the main suppliers of snow leopards, hunting for which for the sake of its fur-skin is prohibited.

Abstract: It provides general information about the Besh Aral nature reserve (Kyrgyzstan), its physico-geographical characteristic, and description of flora and fauna. The predatory mammals are represented by 12 species. The rare predators are brown bear, snow leopard, lynx, and manul. Snow leopard inhabits the highlands of Chatkal depression and the upper-river Kara-Toko. In the past, snow leopards were seen more often.
