Increasing CO2 from subambient to superambient concentrations alters species composition and increases above-ground biomass in a C3 /C4 grassland

•  The glacial-to-present increase in atmospheric CO2 concentration is likely to have stimulated plant production, but experimental tests in natural ecosystems are lacking. •  We measured above-ground biomass production, plant nitrogen (N) accumulation, and species dynamics in a C3 /C4 grassland exp...
