摘要: In multipredator systems, group sizes of social carnivores are shaped by the asymmetric intraguild interactions. Subordinate experience low recruitment rates as an outcome predation pressure. South and Southeast Asia, Tiger (Panthera tigris), Dhole (Cuon alpinus), Leopard pardus) form a widely distributed sympatric guild large carnivores, wherein tigers apex predators followed dhole leopard. this study, we attempted to understand variation in pack size carnivore, dhole, at two neighboring sites Central Indian landscape. We further evaluated local-scale patterns larger scale doing distribution-wide assessment across ranging countries. At local scale, found inverse relationship between density tiger while accounting for variability resources habitat heterogeneity. Larger packs (16.8 ± 3.1) were observed site where was (0.46/100 km2), whereas smaller (6.4 ± 1.3) with high (5.36/100 km2). Our results concordant results, showing negative association densities (effect -0.77) positive prey abundance 0.64). The study advances our understanding answer age-old question "what drives system?" This also highlights importance demographic responses subordinate predator varying competitor densities, often helpful making informed decisions conservation management strategies such population recovery translocation species.
