Community ecology of seagrass dominated ecosystems

Peterson Laboratory page


Research Interests

My research is focused on understanding the role of organisms in changing nutrient availability within their communities and how these interactions might affect community development and stability. I use manipulative experiments in nearshore marine habitats to examine how “resource providers” affect other members of their communities. Most of my work is with plant-animal interactions within seagrass ecosystems along the eastern coast of the U.S. Despite the recognized importance of seagrasses, the critical environmental factors limiting seagrass assemblages are poorly understood, as are the biological interactions that directly and indirectly affect the health of seagrass ecosystems. Recent projects have included looking at the role of sponges in Florida Bay to control phytoplankton blooms and increase light availability to the benthic plant community, the effect of marine protected areas on changing trophic transfer from nearby seagrass foraging grounds on both “no take” and unprotected reefs and the possibility of herbivorous fish creating nutrient “hot spots” around patch reefs. The future direction within my lab will be to focus on positive interactions, bentho-pelagic coupling in near shore environments and ecosystem engineering. Currently, we are investigating the role of hard clams in alleviating light stress of eelgrass by providing elevated nutrients to the sediments via their fecal production and the consequences of the dramatic decrease in hard clam abundance within the Long Island south shore estuaries on eelgrass spatial distribution.

We employ a team approach to problem solving and are carrying out both laboratory and field studies primarily of seagrass-dominated ecosystems at the population and community levels. I have a long-standing interest in elucidating the role played by positive interactions in marine community organization and incorporating positive interactions into current community development models. I am looking for students who are interested in combining community ecology and biogeochemistry to address questions pertaining to the biotic role in controlling nearshore community development and stability.
