Dr. Shurin studies the causes and consequences of variation in species diversity, the flow of energy between producers and consumers, and the impacts of predators on the functioning of ecosystems.
His lab studies the connections between population, community and ecosystem ecology in aquatic environments. They are particularly interested in the flow of energy between trophic levels, the impact of consumers on their resources, and the control of species diversity. They use broad geographic comparisons, mesocosm experiments and theory to address these questions. His students have worked in communities of freshwater plankton, marine fishes and intertidal algae and invertebrates.
