Abstract Aim Theory predicts that the evolutionary adaptations of prey to reduce predator pressure often fail in confrontation with non‐native predators; thus, their predation usually leads to sharp declines of prey populations. However, over time, prey can develop anti‐predator adaptations, reduce predator impact and recover its population. We analyse the numerical response of multiple prey species to the impact of a non‐native predator on a large spatiotemporal scale.
