I am a community and ecosystem ecologist and much of my research is at the interface of these two ecological levels. One major area of my research examines the roles of animals in organic matter and nutrient dynamics; I often consider how anthropogenic factors such as pollutants may alter these roles by modifying organismal physiology and behavior or by modification of community structure.  Another major area of my research focuses on the role of inland aquatic ecosystems in regional and global carbon budgets; I am particularly interested in how this role will change with landscape and climate change.  I head a Research Experience for Undergraduates Program focusing on Assessment and Sustainable Management of Ecosystem Services (EcoREU  https://ecoreu.uark.edu).
