Kachel, S., Bayrakcismith, R., Kubanychbekov, Z., Kulenbekov, R., McCarthy, T., Weckworth, B., Wirsing, A. (2022). Ungulate spatiotemporal responses to contrasting predation risk from wolves and snow leopards. Journal of Animal Ecology, , 1–16.
Abstract: 1. Spatial responses to risk from multiple predators can precipitate emergent consequences for prey (i.e. multiple-predator effects, MPEs) and mediate indirect interactions between predators. How prey navigate risk from multiple predators may therefore have important ramifications for understanding the propagation of predation-risk effects (PREs) through ecosystems.
2. The interaction of predator and prey traits has emerged as a potentially key driver of antipredator behaviour but remains underexplored in large vertebrate systems, particularly where sympatric prey share multiple predators. We sought to better generalize our understanding of how predators influence their ecosystems by considering how multiple sources of contingency drive prey distribution in a multi-predator–multi-prey system. 3. Specifically, we explored how two sympatric ungulates with different escape tactics—vertically agile, scrambling ibex Capra sibirica and sprinting argali Ovis ammon—responded to predation risk from shared predators with contrasting hunting modes—cursorial wolves Canis lupus and vertical-ambushing, stalking snow leopards Panthera uncia. 4. Contrasting risk posed by the two predators presented prey with clear trade-offs. Ibex selected for greater exposure to chronic long-term risk from snow leopards, and argali for wolves, in a nearly symmetrical manner that was predictable based on the compatibility of their respective traits. Yet, acute short-term risk from the same predator upended these long-term strategies, increasing each ungulates' exposure to risk from the alternate predator in a manner consistent with a scenario in which conflicting antipredator behaviours precipitate risk-enhancing MPEs and mediate predator facilitation. By contrast, reactive responses to wolves led ibex to reduce their exposure to risk from both predators—a risk-reducing MPE. Evidence of a similar reactive risk-reducing effect for argali vis-à-vis snow leopards was lacking. 5. Our results suggest that prey spatial responses and any resulting MPEs and prey-mediated interactions between predators are contingent on the interplay of hunting mode and escape tactics. Further investigation of interactions among various drivers of contingency in PREs will contribute to a more comprehensive understanding and improved forecasting of the ecological effects of predators. |

Abstract: There is one subspecies U.u.uncia in Kazakhstan. It is distributed in the Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur, South Altai, and preys mainly on ibex, roe deer, argali, and marmots. Its litter consists of one to five cubs (normally two three). Female bears once in two years.

Abstract: It describes identification signs and taxonomy of genus Uncia Gray and the only representative of genus Uncia uncia Sch., 1778, distribution and some features of the species' biology. A habitat of snow leopard includes the mountains of Central Asia from Kopet-Dag and northern Iran to the east along the mountain systems of Pamir, Turkestan, Gilgit, Tibet, Himalayas before the country Kam. On the north, snow leopard is met in Tarbagatai, Altai, Sayans, and further eastward to the Yablonoviy and Stanovoy ridges reaching the confluence of the Shilka and Argun rivers.

Oshmarin P.G. (1990). Traces in nature.
Abstract: Traces of vital activity of various animal species such as footprints, faeces, food remains, etc. are identified. It also provides information about hunting behavior of predators. Snow leopards would hunt along rather than in groups. Near the remains of prey they leave pieces of skin, skull of victim remaining untouched.

Suryawanshi, K. R. (2009). Towards snow leopard prey recovery: understanding the resource use strategies and demographic responses of bharal Pseudois nayaur to livestock grazing and removal; Final project report.
Abstract: Decline of wild prey populations in the Himalayan region, largely due to competition with livestock, has been identified as one of the main threats to the snow leopard Uncia uncia. Studies show that bharal Pseudois nayaur diet is dominated by graminoids during summer, but the proportion of graminoids declines in winter. We explore the causes for the decline of graminoids from bharal winter diet and resulting implications for bharal conservation. We test the predictions generated by two alternative hypotheses, (H1) low graminoid availability caused by livestock grazing during winter causes bharal to include browse in their diet, and, (H2) bharal include browse, with relatively higher nutrition, to compensate for the poor quality of graminoids during winter. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. Graminoid quality in winter was relatively lower than that of browse, but the difference was not statistically significant. Bharal diet was dominated by graminoids in areas with highest graminoid availability. Graminoid contribution to bharal diet declined monotonically with a decline in graminoid availability. Bharal young to female ratio was three times higher in areas with high graminoid availability than areas with low graminoid availability. No starvation-related adult mortalities were observed in any of the areas. Composition of bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Since livestock grazing reduces graminoid availability, creation of livestock free areas is necessary for conservation of grazing species such as the bharal and its predators such as the endangered snow leopard in the Trans-Himalaya.

Anonymous. (1986). Toward a free-ranging recovery plan.
Abstract: This draft is a first attempt to develop a Snow Leopard Recovery Plan, for consideration at the Fifth International Snow Leopard Symposium. It is intended as a working base for agencies responsible for snow leopard conservation, research and management. The plan, when thoroughly reviewed and revised, will provide more accurate estimates of snow leopard status and threats, and recommendations concerning actions necessary for the maintenance, enhancement and recovery of the snow leopard in its original habitat.
