Understanding the factors that influence the patterns of biodiversity is a central goal in ecology. As a community and ecosystem ecologist, I seek to understand the factors that underlie the processes that determine biodiversity and how those processes are impacted by global environmental problems, such as deforestation and climate change. In particular, I examine how abiotic interactions combine with variations in nutrient acquisition and ecophysiological processes to influence plant distributions and, ultimately, patterns of biodiversity. I am fascinated by species-rich communities and, in particular, those that are threatened by climate change.
I have conducted much of my research in tropical rainforest canopies as they are one of the most diverse yet poorly understood and threatened ecosystems on the planet. I work primarily on the resident plants in tropical forest canopies, vascular epiphytes. Epiphytes are interesting from both a physiological perspective and from a community perspective. The former because of their diverse resource-acquisition strategies and physiological adaptations to extreme nutrient- and water-limitation, and the latter because of their high species richness in a structurally complex environment. Both of these aspects may be influenced by changes in their abiotic environment, such as those predicted with climate change. My dissertation research with Dr. Saara J. DeWalt at Clemson University aimed to understand the factors that influence the distribution of epiphytes at different scales: with forest age, with tree size, and among crown zones within the largest trees. I continue to study the factors that determine the distribution of vascular epiphytes at different scales, particularly examining how these plants, the insects and animals that depend on them, and their microhabitats will respond to disturbances, such as deforestation and climate change.
My collaborative research with Dr. Catherine L. Cardelus at Colgate University examines how ecosystem function and biodiversity will be impacted by the predicted increases in nutrient deposition and decreases in precipitation with global change. This research was done concurrently during my dissertation. I am particularly examining how habitat-partitioning by epiphytes may be affected by changes in nutrient and water availability.
