The spatial structure of а snow leopard population (Panthera uncia, Felidae, Carnivora) in east Kyrgyzstan

The distribution of the snow leopard (Panthera uncia uncia (Shreber, 1775) across its geographic range is associated exclusively with the mountain landscapes. The most important factor in maintaining the integrity and viability of a population is its structure.Our studies were conducted in 2010, 2011 and 2012 and covered most of the range of snow leopard in East Kyrgyzstan. Each territory was surveyed through series of routes. The main methods used in field research were: searching for traces of vital activity, conducting short trail surveys, and using the SLIMS (Snow Leopard Information Management System) technique.In order to study the spatial structure of the snow leopard population, we conducted individual DNA-based identification and GPS registration of bioassays collected from all individuals inhabiting this territory.  Biological samples (tissue, fur, and excrement) were obtained following the protocols for collecting bioassays. A total of 146 samples (2 of wool, 2 of tissue, and 142 of excrement) were collected in nature in the Central Tien Shan Mts within Kyrgyzstan (in the Sarychat-Ertash Reserve, and in the area of the Kainar River).Snow leopard DNA was identified in 70 samples. A total of 21 individual snow leopards (8 females and 13 males) were identified. All females of a local population of the Sarychat-Ertash Reserve, with the exception of one, were directly related to each other. The same is true for most of males (11 of 13). Two females were accompanied by kittens. All females settled near the maternal site, while almost all males, which were born there, move away. There is a direct correlation between population density and marking activity.
