Although studies of species linked by a common resource (i.e. ecological guilds) have so far mainly focused on competition and predation, guilds are also good places to find mutualism. In this review we consider some three- and four-species community modules to illustrate examples of wide relevance. Mutualism arises from various direct and indirect trophic and non-trophic interactions between species¡ªand within modules both with and without intraguild predation. Species removal and augmentation experiments, other manipulations, direct measurements, and path-analytic methods can determine the presence and intensity of mutualism within guilds. Such studies, particularly when associated with existing theory and new theoretical development, can help advance an interaction-based approach to community analysis that recognizes linkages among mutualism, predation and competition in natural systems.
