Variation of biological diversity in space and time is a main topic of ecology. During the last decade, evidence accumulated that diversity dynamics may be equilibrial, i.e. diversity has a tendency to stabilize at regional scales. Understanding the determinants of diversity equilibria and to what extent diversity deviates from equilibria is crucial for understanding future biodiversity changes. Recently, we have proposed a general species-based theory of diversity dynamics that makes predictions concerning the interplay between resource abundance (productivity), environmental stability and species origination rates in determining equilibrium diversity patterns. The aim of the project is to further develop the theory to address spatial dynamics and scale-dependence, to test its individual building blocks and assumptions, and to explore its consequences.
