Research in my lab centers on the ecology of coastal and upland communities such as salt marshes, wetlands, coastal dunes, and upland hammocks. I am primarily interested in how variation in environmental factors influences community dynamics such as plant and insect species diversity and abundance, and the relative importance of food sources versus predation and parasitism on herbivores.


A main focus of my research has been investigating the influence of nitrogen availability and salinity levels on the interactions among plants, herbivorous insects and their predators in salt marshes. Changes in these fundamentally important, but highly variable, environmental factors influence both plants and animals in an astounding array of direct and indirect ways. For example, increasing levels of environmental stress in the form of salinity can have a negative direct effect on herbivores by decreasing food quality, but a positive indirect effect by decreasing frequency of attack by predators and parasites.


The studies on coastal communities that my students and I conduct are important both theoretically and practically. We have applied our findings to evaluating current theories and models of community ecology, as well as to habitat restoration and species conservation. Current projects include examining the effects of elevated CO2 levels on a scrub oak forest ecosystem, investigating food web structure and species diversity in constructed wetlands, and studying the interplay between environmental stress levels and intraguild predation in salt marsh communities.
