Before revision:  This approach has so far been applied primarily to situations of resource competition , in accord with the general focus of work on ecological interactions since the 1970's. In this manuscript, we expand contemporary niche theory to integrate mutualistic interactions through a systematic analysis of mutualistic plant-pollinator networks.
After revision:  This approach has so far been applied primarily to resource competition since its early beginnings. Here, we integrate mutualism into niche theory by expanding Tilman's graphical representation to the analysis of consumer-resource dynamics of plant-pollinator networks.
