Dr. Peterson’s research is focused on understanding the role of organisms in changing nutrient availability within their communities and how these interactions might affect community development, organization, and stability. He examines how “resource providers” affect other members of their communities. Most of his work is with plant-animal interactions within seagrass ecosystems along the eastern coast of the U.S. Recently, his lab has investigated the role of hard clams in alleviating light stress of eelgrass, the consequences of the dramatic decrease in hard clam abundance, and the effect of MPAs on changing trophic transfer from nearby seagrass foraging grounds.
