Department: Ecology, Evolution, and Organismal Biology

Research Interests: C-cycling in grasslands, biodiversity loss, invasion ecology, restoration ecology

Brief description of current research:

Wilsey studies how biodiversity loss affects primary productivity, CO2 uptake and storage, and herbivore consumption in grasslands.  His current research includes studies of how altered rainfall patterns will affect plant biodiversity.
