摘要: Detection of density dependence in animal populations is a primary goal population ecology, and the processes causing play major role regulation. Predation can strongly regulate by populational behavioral responses predators to their prey. Here I evaluate existence strength density-dependent mortality local reef fish, kelp perch (Bra- chyistius frenatus), caused its predator, bass (Paralabrax clathratus). Specifi- cally, examine both functional response potential aggregative as mechanisms underlying predator-induced mortality. calculated per capita result predator subjecting range densities low, constant number different amounts giant (Macrocystis pyrifera) habitat structure prey refuge.
