Apply cross-disciplinary approaches to ecological and environmental assessment and management of complex ecosystems including agriculturally-dominant landscapes, forests, wetlands, conservation lands and refuges. The focus is on understanding process dynamics in open systems with spatio-temporal variation in the intrinsically coupled biological, physical, and social processes. Examples of current areas of importance are environmental and socio-economic consequences of intensive land use for bioenergy production, adaptation to climate change and its impacts on human and ecosystem health, carbon cycling and sequestration in terrestrial ecosystems, mitigation strategies for degraded wetlands, and ecological restoration of riverine and prairie systems within managed ecosystems.
