Ecology (community ecology)

A negative indirect interaction between prey that share a predator

In ecology, apparent competition is an indirect negative interaction between two prey (or host) species that share a common natural enemy: an increase in one prey supports more predators, which then depress the other prey, mimicking the pattern of resource competition without any contest for resources. Robert Holt introduced and named the concept in his 1977 paper in Theoretical Population Biology, distinguishing it formally from exploitative competition. The referent is a predator-mediated, density-dependent interaction between species, identified by its signature of mutual negative effects routed through a shared enemy rather than a shared resource.[1]

Unit
One predator-mediated negative effect between two prey species
Recovery means
Remove or add the shared predator and test for release or suppression of the other prey
Measured by
Detected via the shared-enemy pathway (enemy-exclusion or density-manipulation experiments)
