Abstract

Disentangling impacts of multiple global changes on terrestrial carbon cycling is important, both in its own right and because such impacts can dampen or accelerate increases in atmospheric CO2 concentration. Herein we report on an 8-year grassland experiment, TeRaCON, a subset of the BioCON experiment at Cedar Creek Ecosystem Science Reserve, that factorially manipulated temperature, rainfall, CO2 and nitrogen deposition. Species composition, productivity (NPP), species biomass, soil carbon emissions and plant carbon stocks are measured under all sixteen combinations of two contrasting levels of temperature, rainfall, CO2, and N.
