Acclimation of Roots and Microbes to Soil Warming investigates respiratory temperature acclimation in roots, mycorrhizae and the microbial community and whether such acclimation is a short-term, direct physiological adjustment to warmer temperatures (days to months) or a longer term response to changes in nutrient, moisture and C availability and mycorrhizal status as the ecosystem adjusts to long-term warming (years).  The experiment examines the potential impact of adjustments in root system activity on ecosystem productivity and the potential for soil CO2 efflux to be a positive feedback contributing to greater atmospheric CO2 increase and warming.  (Burton, Lilleskov)
