An overview of the study of organisms interacting with each other and their environment at individual, population, community, and ecosystem levels of organization. Includes human interaction with ecological systems.
My research program focuses on the high tree diversity in the tropical forest. How can so many species coexist in the same forest? To address this question, I combine field observations, computer approached, and theoretical modeling. The majority of tropical tree species associate with arbuscular mycorrhizal fungi. These mutualists can alter the effects of natural enemies (herbivores, pathogens, etc) on seedling dynamics. My research program investigates how natural enemies and fungi influence seedling dynamics and plant species coexistence. A second main question of my research program is to understand how plant communities are responding to climate change. I am currently collaborating on a tropical warming experiment in Puerto Rico to uncover some of the effects of warming on understory plant communities in a tropical rainforest.
