Environmental Biology, Ecology, Graduate Research Methods
Research in my lab focuses on the ecology of freshwater ecosystems. Most of my recent and ongoing work has focused on tropical headwater streams in Puerto Rico and Panama. Additionally, my students and I are involved in research efforts to explore the ecology of coastal plain streams, rivers and wetlands in southeastern Georgia. Major themes in my projects and those of my students include the effects aquatic consumers (invertebrates, fish, amphibians) in organic matter dynamics, nutrient cycling, and energy flow in streams and other freshwater habitats.
