Brief description of current research:

Dr. Harpole’s research focuses on the mechanisms that control species diversity as a way to predict the consequences of global change to diversity. His lab tests and develops biodiversity theory using experimental and observational studies of plant communities in combination with mathematical and statistical models and simulations. Current projects include the Nutrient Network, a global experiment of nutrient and herbivore control of plant productivity and diversity; testing alternative state theory and the roles of grazing, invasion, and spatial processes; demography and conservation of endemic California oaks.
