The range dynamics of species results from the dynamics of local populations that are connected by dispersal. This general relationship forms the foundation of a demographic approach to plant biogeography that combines process-based models of local dynamics and long-distance seed dispersal with functional trait measurements, experiments and observational data. Using examples from European and African plant species, I will show that this demographic approach can explain large-scale distributions and dynamics, and that it provides a basis for understanding how evolutionary and community-level processes shape range dynamics. Furthermore, the integration of this approach into a statistical framework substantially improves our ability to forecast the range dynamics of species exposed to environmental change.
