Biological invasions are known have highly variable impacts on ecosystem processes. We’re investigating the biogeochemical impacts of one of the most widespread invasive plant species in the eastern US, Microstegium vimineum (Japanese stiltgrass), in order to develop a framework to explain how and why invasion impacts differ across the landscape. Specifically, we’re examining whether species have the largest impacts where they are in greatest abundance, or where they function most differently from the resident vegetation with respect to nutrient cycling.
