My research focuses on trophic interactions within the mud flat/salt marsh communities in Maine. Through field experiments in a salt marsh located at the Wells National Estuarine Research Reserve in southern Maine, I examine how consumptive and nonconsumptive effects of C. maenas on L. littorea indirectly influence benthic macroinfaunal density and diversity and how these interactions could affect marsh primary production as well as nutrient availability.
