Stable coexistence in insect communities due to density- and trait-mediated indirect effects

Abstract:

Density-mediated and trait-mediated indirect interactions between species may have important roles in structuring ecological communities. Here we dissect their contributions to community stability in a model herbivore-natural enemy interaction consisting of two aphid species (Acyrthosiphon pisum and Megoura viciae) and a specialist parasitoid (Aphidius ervi) that attacks only one of the aphids (A. pisum). In replicated cage experiments, we found that the two aphid species alone were unable to...
