Seminar: Applying Ecological Stoichiometry to Manage Freshwater Ecosystems


Population management requires an understanding of the interactions between species of interest and the ecosystems they inhabit. Using the common currency of individual chemical elements and energy, ecological stoichiometry provides a framework to investigate these interactions. In this seminar, I will describe how ecological stoichiometry can be applied to freshwater conservation and provide two case studies from my research. First, I will talk about how variation in nutrient availability across habitats affects production of a threatened desert fish, the humpback chub (Gila cypha). I will also discuss how urbanization affects water quality in streams in Vermont, where chloride pollution affects the energy demands of sensitive benthic invertebrates. Finally, I will discuss ideas for how ecological stoichiometry could more broadly be integrated into conservation biology and natural resource management.
