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.

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.

Seidensticker, J., & Lumpkin, S. (1996). The adaptable leopard; unfortunately it's no match for modern man. Wildlife Conservation, 99(3), 52.
Abstract: Abstract: Leopards' adaptability has become the species' vulnerability. The animals do not hesitate to eat rotting flesh and will come back repeatedly to their meal, if disturbed. People have taken advantage of this by lacing carcasses with poison. Leopards are moderate in size compared to other cats, are stealthy and can live in areas as diverse as rain forests and deserts.

Abstract: Geo-botanic and zoogeographical description of altitude landscape zones of Central Asia is given. Snow leopard (Felis irbis), ibex (Capra sibirica), brown bear (Ursus leuconyx), dhole (Canis alpinus) and others (10 species in total) are vertically distributed (2,348 3,048 m) in the deciduous forest, fir forest and alpine meadow zones.

Shafiq, M. M., & Abid, A. (1998). Status of large mammal species in Khunjerab National Park. Pakistan Journal of Forestry, 48(1-4), 91–96.
Abstract: Study on the current status of large mammals species population was carried out in Khunjerab National Park, Northern Areas. The observation recorded showed that the population of Tibetan Red fox (Vulpes vulpes montana), Snow leopard (Uncia uncia), and Wolf (Canis lupus) have, though a bit, increased but are still in the rank of “Endangered”. While the population of Himalyan Ibex (Cpara ibex sibirica) is increasing more rapidly and their status is now “Common” in the Park. The limited population of Marcopolo sheep (Ovis ammon polii), Tibetan wild Ass (Equus hemionus kiang) and Brown bear (Urus arctos) is still under threat, and comes them under “Critical Endangered” category.

Abstract: The analysis of the data of national collection of Parasitological museum of Kazakh Antiplague Institute on ectoparasites from 12 species of carnivores that can be found in Kazakhstan: caracal, snow leopard, ermine, mountain weasel etc. helped to determine the species of fleas and their hosts specialization. Fleas were found on 57 animals/ 50 species of fleas were found, which can be specified to 23 genera, the total number is 525. The specific ones for the carnivores are 6 species fleas. The very low density of ectoparasites was indicated for caracal and snow leopard.
