Proposed a simple classification of the effects of predation upon the outcome of competition. The basic idea is to distinguish between those effects that are mediated directly or indirectly through changes in prey population densities brought about by predator-inflicted mortality (trophic-link indirect effect), and those mediated through changes in prey behavior which affect the intensity of competition among the prey species and are brought about in response to changes in the risk of predation (behavioral indirect effect). The authors discuss some of the diverse outcomes to be expected in systems with a mixture of predation and competition, and for illustration, relate theoretical models to a few examples from natural communities. -from Authors
