Simple omnivory and generalist food web modules. (A) Omnivore module showing an omnivore's (species 4's) feeding links to intermediate consumer 2 and basal resource 1. (B) Generalist module showing a generalist consumer G and its feeding links to its numerous resources (Ri). Each resource Ri has a competitively dominant specialist consumer Si that feeds on it. As a result, generalist G experiences competition at the regional scale for occupancy of each Ri resource patch from competitively dominant specialist Si.
