Carbon and nitrogen relationships in swards of Danthonia richardsonii in response to carbon dioxide enrichment and nitrogen supply
Atmospheric C0₂ concentrations are increasing steadily, although not fast enough to account for all anthropogenic emissions. Uptake of extra carbon by the terrestrial biosphere in response to the CO₂ concentration increase may, in turn, be moderating the rate of increase. However, there are uncertainties pertaining to the ability of natural ecosystems to respond to this increase in terms of productivity and carbon sequestration, when productivity is restricted by nitrogen availability....[Show more]
