Lines of inquiry have been along understanding how fluxes of mass and energy between ecosystems and the atmosphere vary along a spectrum of time and space scales in accordance with structure, function, weather and climate and management. Â Methods used include use of the eddy covariance method to measure net fluxes of mass and energy across the atmosphere-ecosystem interface. Â Data are interpreted and distilled through the lens of the CANVEG family of models, physiological measurements at the leaf scale and flux measurements across the soil-atmosphere interface.
Current work focuses on: 1) the roles of management and ecological restoration on greenhouse gas fluxes of crops and wetlands; 2) the impact of weather, climate trends and variability, physiological stress, and structure and function on the greenhouse gas fluxes of savanna woodlands and annual grasslands; and 3) the upscaling and interpretation of fluxes across climatic and ecological gradients with the AmeriFlux and FLUXNET networks.
