Our research program addresses questions related to the mechanisms that structure stream and riparian area communities, and how various land-use practices affect those systems. In natural communities there are many processes that affect the rates of population growth (or decrease). We have taken a largely experimental approach to determining what those feedback processes are, how the rates are regulated, and how the multiple sets of interactions combine to affect population sizes and community structure. These kinds of questions are important for being able to predict the effects of human impacts on natural systems.
