The primary goal of the doctoral program in ecological sciences is to provide advanced training in ecological, evolutionary and integrative biology. The program has notable strengths in a broad range of biological subdisciplines, including ecosystem studies, experimental ecology, population biology, conservation biology, systematics, evolutionary biology, biomechanics, and comparative and functional morphology. Program faculty conduct studies in a variety of terrestrial, freshwater, and marine environments on several continents, and their research focuses on a broad spectrum of taxa, including, but not limited to, vascular plants, polychaetes, mollusks, crustaceans, insects, fishes, amphibians, and reptiles.
