Apparent competition and native consumers exacerbate the strong competitive effect of an exotic plant species

Ecology, 2015
Direct and indirect effects can play a key role in invasions, but experiments evaluating both are rare. We examined the roles of direct competition and apparent competition by exotic Amur honeysuckle (Lonicera maackii) by manipulating (1) L. maackii vegetation, (2) presence of L.

Apparent competition between parasitoids mediated by a shared hyperparasitoid

Ecology Letters, 2000
Cocoons of the specialist parasitoidCotesia melitaearum, which attacks the Glanville fritillary butterfly in the Ă…land islands of SW Finland, are parasitized by the generalist hyperparasitoidGelis agilis. We added experimentally to the system a second host species forG. agilis,C. glomerata, with whichC. melitaearumdoes not compete for resources.

Predation, apparent competition, and the structure of prey communities

Theoretical Population Biology, 1977
Abstract It is argued that alternate prey species in the diet of a food-limited generalist predator should reduce each other's equilibrial abundances, whether or not they directly compete. Such indirect, interspecific interactions are labeled apparent competition . Two examples are discussed in which an observed pattern of habitat segregation was at

Short-Term Apparent Competition

The American Naturalist, 1987
Interspecific interactions reflect the cumulative consequences of individual behavioral acts. The foraging decisions made by predators influence the way in which predation shapes the structure of prey communities. Alternative prey species co-occurring in a patch embedded in a matrix of many similar patches may interact through a shared mobile predator ...

Apparent competition and recovery from infection

Journal of Theoretical Biology, 2004
We use mathematical models to analyse how the recovery rate from infection influences the fitness of a host in a setting of interspecific competition. We show that sub-optimal immunity against pathogens can be advantageous for the host in the presence of cross-species infection. Weaker immunity allows the parasite to be used as a biological weapon, and
