Recent advances in the research field of ‘biodiversity‐ecosystem functioning’ have successfully begun to reconcile the apparent controversy on relationships between productivity and species richness. By unifying new advances into a single framework, I propose a 3D graphical model connecting the relationships among resource availability, species richness, and ‘community productivity.’ An emergent pattern from this model predicts that the effect of species richness on community productivity is maximized at intermediate levels of resource availability. This model will contribute to better understanding the relationships among environment, biodiversity, and ecosystem functioning.
