Integrative models explain the relationships between species richness and productivity in plant communities

Abstract The relationship between plant productivity and species richness is one of the most debated and important issues in ecology. Ecologists have found numerous forms of this relationship and its underlying processes. However, theories and proposed drivers have been insufficient to completely ex...
