 "... and dhole had low rates of co-occurrence with tiger, and their detection probabilities were 47–52% lower in tiger-occupied open habitat (compared to closed), despite suitable prey there. Tiger occupancy was highest in prey-rich zones, whereas dholes were concentrated in a prey-poor zone where tigers were scarce, suggestive of mesopredator release. Activity periods of leopard and dhole (diurnal) were significantly different from tiger (nocturnal). In sum, tiger distribution appeared to be driven solely by prey availability, whereas leopard and dhole seemed to be influenced by prey availability and avoidance of tigers, mediated by habitat structure. Results agree with predictions that under intraguild predation the dominant predator’s distribution matches its resources, whereas intermediate predators trade-off food and safety."
