Research overview: the landscape of fear created by big cats

Beyond killing prey, big cats shape ecosystems through the fear they inspire, altering where and how prey forage. This overview synthesizes research on the landscape of fear, in which the risk of predation by lions, tigers, leopards, or pumas leads prey to avoid dangerous areas, increase vigilance, and shift activity, with cascading effects on vegetation and habitat. It reviews how these non-lethal effects can rival direct predation in their ecological influence, and how the spatial pattern of risk across a landscape structures prey behavior. The synthesis frames fear as a key mechanism by which predators exert top-down effects. For enthusiasts it explains why prey behave differently near cover or water where cats lurk, how the mere presence of predators reshapes herbivore behavior, and why the ecological role of big cats extends well beyond the animals they actually catch.
