The Plant Evolutionary Ecology Lab in the Department of Horticulture and Crop Science at the Ohio State University is directed by Dr. Kristin Mercer. In general, we study plant evolutionary ecology within agricultural systems. Of primary focus is the way that dynamics of ecological processes and evolutionary forces influence important issues in agricultural sustainability, such as conservation of crop genetic resources in centers of origin and biosafety of genetically modified crops.
