Schmidt, A. M., Hess, D. L., Schmidt, M. J., Smith, R. C., & Lewis, C. R. (1988). Serum concentrations of oestradiol and progesterone, and sexual behaviour during the normal oestrous cycle in the leopard (Panthera pardus) (Vol. 82).
Abstract: Three mature nulliparous female leopards were studied for 5 years. During three separate 6-month periods serum oestradiol and progesterone concentrations were measured at weekly intervals. Oestradiol was elevated over 21 pg/ml for 54 weeks during these 3 periods, and 36 oestradiol peaks (65\m=.\8\m=+-\6\m=.\3pg/ml (mean \m=+-\s.e.m.), range 21\p=n-\172pg/ml) were identified. Daily frequency of feline reproductive behaviours averaged over each week increased from 1\m=.\9\m=+-\0\m=.\2(n = 93) during weeks with low serum oestradiol concentrations (<21 pg/ml) to 5\m=.\3\m=+-\0\m=.\6(n = 54) during weeks when serum oestradiol concentrations (>21 pg/ml) were high. Increased serum progesterone concentrations (13\p=n-\98n/gml) were observed on 5 occasions in 2 leopards housed together. These presumptive luteal phases lasted from 1 to 5 weeks. Baseline progesterone values were 1\m=.\6\m=+-\0\m=.\4 ng/m(nl= 131). No progesterone increments were observed in isolated animals, and serum concentrations remained at baseline levels. These limited observations suggest that female leopards do not require intromission to induce ovulation and luteal function. The average interval between oestradiol peaks for cycles with no progesterone increment was 3\m=.\4weeks (range 1\p=n-\6weeks). The interval for the 3 complete cycles associated with elevated progesterone concentrations was 7\m=.\3weeks. Analysis of sexual behaviours over the 5-year study period revealed no evidence of seasonality in these
captive leopards.

Oruntaeva K.B. (1988). The Zailiyskiy natural national park.
Abstract: The Zailiyskiy state natural national park is suggested to establish in the center of northern micro slope of Zailiyskiy Alatau. There are 42 mammal, 138 bird, tow amphibian, and eight reptile and fish species, and 145 daylight butterfly species in the Zailiyskiy Alatay. Of them, seven mammal species such as argali, Tien Shan bear, snow leopard, Turkistan lynx, stone marten, Central Asian otter, and Indian porcupine are included in the Red Data Books of Kazakhstan and USSR.

Moiseev V.A. (1988). Mountain nature.
Abstract: The snow leopard inhabits the upper belt of the Tien Shan, Hissar Alai and Pamir mountains. More often it hunts for wild ibexes. Irbis avoids meeting … man, and even wounded it rarely attacks him. At the beginning of spring … snow leopard gives birth to two-five cubs. It lives up to 21 years. The snow leopard is registered in the Red Data Book of USSR and IUCN Red List.

Abstract: Snow leopard behavioral patterns, food preferences, and reproduction are described in a popular way. The population of snow leopard is defined to be 1,000 animals. A reason for the population decline is hunting for the sake of beautiful fur.

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.
