Abstract
Mammalian communities inhabiting temperate grasslands are of conservation concern globally, and especially in Central Asia, where livestock numbers have dramatically increased in recent decades, leading to overgrazing and land-use change. Yet, how this pervasive presence of livestock herds affects the community of wild mammals remains largely unstudied. We used systematic camera trapping at 216 sites across remote, mountainous areas of the Mongolian Altai to assess the spatial and temporal patterns of occurrence and the inter-specific relationships within a mammalian community that includes different categories of livestock. By adopting a recently proposed multi-species occupancy model that incorporates inter-specific correlation in occupancy, we found several statistically strong correlations in occupancy among species pairs, with the majority that involved livestock. The sign of such associations was markedly species-dependent, with larger wild species of conservation concern, namely snow leopard and Siberian ibex, avoiding livestock presence. As predicted, we found evidence of a positive correlation in occupancy between predators and their respective main prey. Contrary to our expectations, a number of intra-guild species pairs also showed positive co-occurrence, with no evidence of spatio-temporal niche partitioning. Overall, our study suggests that livestock encroaching into protected areas influences the whole local community of wild mammals. Though pastoralism has co-existed with wildlife for millennia in central Asian grasslands, our findings suggest that policies and practices to decrease the pressure of livestock husbandry on wildlife are needed, with special attention on large-sized species such as the snow leopard and its wild prey, which seem to be particularly sensitive to this pervasive livestock presence.
