  • IN trying to understand the structure of ecological communities, ecologists usually pay particular attention to the interactions between pairs, or small groups of species1. Questions about the ‘shape’ of the food webs within which these species are embedded are much more rarely asked2–4. For example, what happens when a population feeds at more than one trophic level (omnivory)? In some real food webs there seem to be no omnivores (Fig. 1a)5; in others omnivores are common6,7 (Fig. 1c)8. In… CONTINUE READING
