Determining underlying physiological patterns governing plant productivity and diversity in grasslands are critical to evaluate species responses to future environmental conditions of elevated CO2 and nitrogen (N) deposition. In a 9-year experiment, N was added to monocultures of seven C3 grassland species exposed to elevated atmospheric CO2 (560 μmol CO2 mol-1) to evaluate how N addition affects CO2 responsiveness in species of contrasting functional groups. Functional groups differed in their...[Show more]
