Holt, C. D. S., Nevin, O. T., Smith, D., Convery, I. (2018). Environmental niche overlap between snow leopard and four prey species in Kazakhstan. Elsevier, (48), 97–103.
Abstract: The snow leopard Panthera uncia has declined due to habitat loss, habitat fragmentation and human persecution. Predator distribution is heavily dependent on prey species availability and distribution. With increasing pressures from farming practices encroaching into native species range and persecution of snow leopards in response to livestock depredation, it is vital to assess current predator and prey species distribution to highlight sensitive areas of overlap for protection. This study uses MaxEnt, a presence-only Species Distribution Model (SDM) to assess snow leopard and four prey species habitat suitability along
the southern and eastern borders of Kazakhstan using environmental data. This area is considered an important corridor between snow leopard populations in the north and south of their range. Each of the five SDM's produced models of �good� discriminating abilities. We then compared the potential niche overlap between snow leopard and four prey species using ENMTools to highlight areas of important niche overlap within the corridor. The results indicated a very high degree of overlap between snow leopard and Siberian ibex and high degrees Capra sibirica with red deer Cervus elaphus, argali Ovis ammon and urial Ovis orientalis. The snow leopard population in this region is also found to be using forested areas below 2500 m, much lower than recorded in other areas of their range. The results highlight areas needed for protection but also pose additional conservation questions regarding the importance of prey species to transitory individuals. |
Aizin B.M. (1969). Siberian ibex Capra sibirica Pall.
Abstract: It describes status of ibex in Kyrgyzstan, its distribution, behavioral patterns, enemies and competitors, etc. The enemies of ibex are snow leopard and wolf. All year round snow leopard preys on ibex its main food object and, therefore, should there be ibexes, snow leopards would be somewhere around. In winter, a considerable number of ibex dies from wolves. Sometimes dogs prey on ibex, too. Golden eagles and bearded vultures prey on young ibexes. However, poachers remain the most dangerous enemy.

Abstract: During November 1985 through July1996, a survey of snow leopard presence and ecology was conducted in selected areas of the states of Jammu and Kashmir, Himachal Pradesh, and Uttar Pradesh in north-western India. The study was carried out under the auspices of the Wildlife Institute of India in cooperation with the U.S. Fish and Wildlife Service and the International Snow Leopard Trust. The objectives of the survey were essentially determine the relative presence of the snow leopard and its associated prey species,investigate human interaction with the snow leopard and select an appropriate site for more intensive studies of the snow leopard and its ecosystem.

Kovshar A.F. (1982). A problem of rare and endangered animal species in Kazakhstan.
Abstract: The Red Book of the Kazakh SSR includes 91 rare and endangered vertebrate animal species: 30 mammal, 48 bird, eight reptile, one amphibian, and four fish species. 26 species (Menzbier's marmot, marten species, lynx, snow leopard, and other species) became rare because of a direct anthropogenic pressure. The prohibition of hunting, conservation and rehabilitation of their habitats, reproduction in enclosures and preservation of some species' genomes is a way that would conserve rare species, the authors believe.

Koshkarev E.P. (1989). Snow leopard in Kyrgyzstan. The structure of habitat, ecology, protection.
Abstract: Habitat, status of population, geographical distribution, number, and ecology of snow leopard in Tien Shan are analyzed based on original realistic material collected 1981 through 1988.Information about irbis in the `foreign' part of its habitat is given for comparison. The reasons for snow leopard habitat shrinkage in Central Asia and Kazakhstan for over 100 years are assessed. Status of ungulate populations snow leopard prey on is given. The predator's behavioral pattern and condition in enclosure are given consideration. Protection measures are proposed.

Kovshar A.F. (1982). Preservation of gene pool of rare and endangered animal species.
Abstract: The rare species are protected in six nature reserves in Kazakhstan, including 9 mammals, 29 birds, and one reptile species. More than 20 rare and endangered species inhabiting Kazakhstan cannot be met within the nature reserves. The point is to establish a network of state nature reserves, particularly in steppe and desert area of the country.

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.

Williams, P. A. (2006). A GIS ASSESSMENT OF SNOW LEOPARD POTENTIAL RANGE AND PROTECTED AREAS THROUGHOUT INNER ASIA; AND THE DEVELOPMENT OF AN INTERNET MAPPING SERVICE FOR SNOW LEOPARD PROTECTION. Master's thesis, , .
Abstract: Snow leopard distribution knowledge is a critical conservation need. During the 2003 Snow Leopard Symposium, a pressing demand for a comprehensive collection of observation data became apparent. Expanding the knowledge of population distribution will help identify areas for conservation and add validity to the potential range map developed by Hunter and Jackson (1997). An equally strong need is an analysis of the extent of protected-area coverage of snow leopard habitat. Another crucial requirement is accurate representation and immediate availability of data to researchers throughout the range.
This project was developed in cooperation with the International Snow Leopard Trust, the Snow Leopard Conservancy, and International Center of Applied Ecology. It is also supported by the Snow Leopard Network, an affiliation of individuals working together to establish effective conservation of the snow leopard throughout Inner Asia. The specific goals of this project are to collect and graphically depict existent knowledge of snow leopard distribution and identify areas lacking data; evaluate the potential range map; assess protected areas to see if snow leopards occur indiscriminately; and produce an internet geographical database and interactive mapping service for research. This thesis validates the potential range map created by Jackson and Hunter (1997). The majority of sightings (88%) fall within the modeled potential range. This suggests that the map is accurate in representing habitat that supports snow leopards. The thesis also highlights varying degrees of support for protected areas. Most of the potential range lies outside of protected areas. Consequently, most countries contain less than 47 percent of their sightings within protected area boundaries. This thesis organized and analyzed existing snow leopard data in a geodatabase to evaluate the potential range map and effectiveness of protected areas throughout the range. The geodatabase and internet mapping service provides a standardized method of data exchange and communication among researchers. This is a small step forward in the conservation of the snow leopard, but creates a necessary foundation for future collaborative data exchange projects to follow. The technologies and methodologies used here should be expanded to meet the individual needs of projects. |
