Kurzfassung
In trophic interactions, predator effects on prey populations through consumption are often exceeded by non-consumptive effects that predators elicit on prey behaviour. Spiders can elicit strong antipredator behaviour in both insects and other spiders. However, antipredator behaviour has only been investigated in a limited number of insect and spider species. We investigate the occurrence and strength of antipredator behaviour across 18 spider and 18 insect species that cover a wide taxonomic...In trophic interactions, predator effects on prey populations through consumption are often exceeded by non-consumptive effects that predators elicit on prey behaviour.
