- Abstract
Indirect effects occur when one species alters the effect that another species has on a third. Data on the relative importance of indirect versus direct effects on community structure are still lacking. A specific type of indirect effect called "predator-mediated apparent competition," where two prey species with a common predator have a reciprocal negative interaction. For apparent competition to occur, the natural enemy must provide an important source of mortality or decreased fitness and the enemy must respond to an increase or decrease in one prey population with a corresponding increase or decrease in attack on the second prey species.
