Timothy  Seastedt
Research Interests Terrestrial ecosystem studies, including factors influencing biodiversity, productivity, soil carbon dynamics, decomposition and mineralization processes, and how these processes affect short and long-term ecosystem-atmosphere interactions. Most recently my research has involved studies of invasive plant species and invasibility of ecosystems within the context of other components of global change.
