Landscape heterogeneity shapes predation in a newly restored predator–prey system
Abstract Because some native ungulates have lived without top predators for generations, it has been uncertain whether runaway predation would occur when predators are newly restored to these systems. We show that landscape features and vegetation, which influence predator detection and capture of p...
