Hunting‐mediated predator facilitation and superadditive mortality in a European ungulate
Abstract Predator‐prey theory predicts that in the presence of multiple types of predators using a common prey, predator facilitation may result as a consequence of contrasting prey defense mechanisms, where reducing the risk from one predator increases the risk from the other. While predator facili...
