For example, prey species may move from areas perceived as risky to safer spaces where predation risk is lower, which can have important consequences for investment in foraging, movement, and mating, and for the behaviour and habitat use of other species, such as mesopredators. These changes in prey and mesopredator behaviours are likely mediated by the presence of predator cues in t...
