Suryawanshi, K. R., Redpath, S., Bhatnagar, Y. V., Ramakrishnan, U., Chaturvedi, V., Smout, S. C., Mishra, C. (2017). Impact of wild prey availability on livestock predation by snow leopards. Royal Society Open Science, , 1–11.
Abstract: An increasing proportion of the world�s poor is rearing
livestock today, and the global livestock population is growing. Livestock predation by large carnivores and their retaliatory killing is becoming an economic and conservation concern. A common recommendation for carnivore conservation and for reducing predation on livestock is to increase wild prey populations based on the assumption that the carnivores will consume this alternative food. Livestock predation, however, could either reduce or intensify with increases in wild prey depending on prey choice and trends in carnivore abundance. We show that the extent of livestock predation by the endangered snow leopard Panthera uncia intensifies with increases in the density of wild ungulate prey, and subsequently stabilizes. We found that snow leopard density, estimated at seven sites, was a positive linear function of the density of wild ungulates�the preferred prey�and showed no discernible relationship with livestock density. We also found that modelled livestock predation increased with livestock density. Our results suggest that snow leopard conservation would benefit from an increase in wild ungulates, but that would intensify the problem of livestock predation for pastoralists. The potential benefits of increased wild prey abundance in reducing livestock predation can be overwhelmed by a resultant increase in snow leopard populations. Snow leopard conservation efforts aimed at facilitating increases in wild prey must be accompanied by greater assistance for better livestock protection and offsetting the economic damage caused by carnivores. |

Graham, L. H., Goodrowe, K. L., Raeside, J. I., & Liptrap, R. M. (1995). Non-invasive monitoring of ovarian function in several felid species by measurement of fecal estradiol-17-beta and progestins. Zoo Biology, 14(3), 223–237.
Abstract: An extraction and assay procedure to measure fecal estradiol-17-beta and progestin concentrations in several cat species was developed and validated for use for noninvasive monitoring of ovarian function. Fecal samples were collected over a range of 3-20 months from female tigers (three), lions (three), snow leopards (three), cheetahs (two), caracals (two), and domestic cats (five). Samples were extracted with 90% methanol, lipids removed with petroleum ether, and the estradiol and progestins in the methanol measured by radioimmunoassay (RIA). High Performance Liquid Chromatography (HPLC) fractionation and subsequent RIA of the fractions indicated that the estradiol-17-beta antiserum cross-reacted primarily with estradiol-17-beta in the feces of lions and tigers and was assumed to be specific for estradiol-17-beta in the feces of other species as well. However, there were several immunoreactive compounds, presumably progesterone metabolites, excreted in the feces which varied both quantitatively and qualitatively among species. The behavior of tigers, lions, cheetahs, and caracals was visually monitored during the collection period and frequency of sexual behaviors was positively correlated with increases in fecal estradiol in all species observed. The mean fecal estradiol-17-beta peaks were as follows: tigers, 128.0 +- 13.1; lions, 186.0 +- 14.8; snow leopards, 136.7 +- 15.9; cheetahs, 140.9 +- 9.0; caracals, 24.5 +- 4.0; and domestic cats 158.9 +- 19.3 ng/gm. Fecal progestin concentrations rose significantly (P lt 0,001) only after breeding or during pregnancy and were as follows: tigers, 5.6 +- 0.6; lions, 1.9 +- 0.1; cheetahs, 8.4 +- 1.1; and caracals, 2.4 +- 0.4 mu-g/gm. Fecal progestins were elevated for one-half to two-thirds of the gestation length during presumed pseudopregnancy but remained elevated throughout successful pregnancies. These results suggest that ovarian function can be monitored noninvasively in the family Felidae by the measurement of fecal estradiol-17-beta and progestin concentrations.

Kovshar A.F. (2001). About the necessity to alter the border of Aksu Jabagly nature reserve (Vol. Vol. 8.).
Abstract: An extension of the Aksu Jabagly nature reserve is suggested in order to improve effectiveness of rare and endemic species conservation in the West Tien Shan. The existing area of the nature reserve is large enough for conservation and reproduction of most of the large mammal species such as ibex, bear, wild boar, snow leopard; the area is however insufficient for species such as Tien Shan argali, roe-deer, whose seasonal migrations extend beyond the area of the nature reserve, as well as Menzbier's marmot a rare endemic to the West Tien Shan, whose habitat is situated 10 15 km from the nature reserve.

Esipov A.V. (2000). Current state of snow leopard and its main preys in Hissar nature reserve.
Abstract: An expert evaluation of the numbers of snow leopard and its preys, Siberian ibex and long-tailed marmot, was made on the basis of surveys conducted in Hissar nature reserve in 1999. The total number of the snow leopard is estimated at 12-16 individuals, whereas that of the Siberian ibex at 1000 individuals. An average density of the population of the long tailed marmot ranges at 4,8 individuals per ha. The ratio of the numbers between the snow leopard, Siberian ibex and long tailed marmot is 1:68:450. The major threats for the snow leopard are poaching on the borders of the nature reserve, a decrease in of preys, shrinking of the range in areas adjoining the nature reserve as a result of intensification of industrial activities and disturbing factors. For the Siberian ibex and long tailed marmot the major limiting factors are the shrinking of the areas and deterioration of the forage value of the high-mountain pastures, as well as the direct competition for forage with domestic animals at the sites adjoining the territory of the nature, as well as disturbing factors.

Abdunazarov B.B. (1990). Composition, structure and population of rare terrene vertebrate animals and their conservation perspectives in the nature reserves of Uzbekistan.
Abstract: An attempt of analyzing the role of Uzbekistan' nature reserves in conservation of gene pool of the rare and endangered terrene vertebrate fauna is done. Of 21 rare vertebrate species, 11 mammal species, eight nesting bird species and two reptile species were detected to inhabit seven nature reserves. This makes up 36.2 percent within the total number of species included in the Red Data Book of the Uzbek SSR or 3.7 percent of the country's fauna. Single snow leopards were found in the Chatkal and Hissar nature reserves. Data of the species inhabiting the Zaamin nature reserve needs to be verified.

Kashkarov, E. (2017). ZOOGEOGRAPHICAL DISCOVERIES IN WESTERN BERINGIA.208–217.
Abstract: Among zoogeographical discoveries of the frontier of XXI century there is nothing more interesting
than discoveries of Rodion Sivolobov in Western Beringia. Beringia has surprised us by paleontological discoveries many centuries ago, and also surprised by modern one. Somehow they came out of attention of all International environmental foundations and Academies of the world, as if on purpose to show their professional incompetence. It is the only way to describe the organization, not to notice the appearance of such big cats as the Snow leopard and Amur tiger for 5,000 kilometers from the border of main range, as well as large Pleistocene relict � the Irkuyembear. All three endangered species of mammals found by Sivolobov in Koryakia and Chukotka, and for the snow leopard he took the world's first photo in Beringia. New facts suggests two things: (1) the ancient refuges of big cats locate to Koryakia and Chukotka much closer of main ranges, (2) global warming, changing natural environment on the waves of hundred-year rhythms, periodically pushing irbis and tiger on the ways of ancient Beringian migrations stored in their genetic memories. Irkuyem is a contemporary of the mammoth. 209 Unlike it, this bear lived up to our days, but remained undetected even by the large “mammoths” of science. |
