Experimental and theoretical studies on the physical, biological and chemical control of trace gas exchange between vegetation and the atmosphere. Goals of work are to predict fluxes of carbon, water and energy, mechanistically, everywhere, all of the time.
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. Methods used include use of the eddy covariance method to measure net fluxes of mass and energy across the atmosphere-ecosystem interface. 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.
