Research Questions

Changes in biodiversity through space and time constitute some of the most striking features of life on earth and have broad implications for human health, the production of renewable resources, and global climate regulation. Our research group seeks to understand patterns of biodiversity at multiple scales and why changes in biodiversity emerge through the interplay of fundamental processes that add species (speciation & dispersal) or limit species membership (ecological drift & niche selection) in ecological communities. We explore this question by integrating concepts from community ecology, biogeography and evolutionary biology, and plant functional ecology. Our empirical approaches combine field experiments, large-scale and long-term observations, ecological modeling, and synthesis of biodiversity data from a wide range of plant communities spanning temperate and tropical ecosystems. We focus on the following questions:
