Food and habitat provisions jointly determine competitive and facilitative interactions among distantly related herbivores (2019) Pan et al., Ecology Letters, https://doi.org/10.1111/1365-2435.13456
Community structure, or the makeup of species within a given habitat, is largely determined by the interactions between the organisms that feed on plants. As such, the effects that different herbivores have on one another may impact how they feed, which would then feed back into which plants that are consumed, which would impact community structure. When one herbivore has a positive effect on the feeding of another, this is called facilitation.
Classically, facilitation has been studied as a one-way interaction (Species A facilitating Species B), but this ignores the reality of natural systems, where any interaction between species has the potential to act both ways. Today’s study investigated three different herbivores to investigate how they may interact with and/or facilitate one another.
