Maximum CO 2 ‐assimilation rates of vascular plants on an Alaskan arctic tundra slope
Light‐saturated CO 2 ‐assimilation rates of 19 vascular plant species were measured on a tundra slope in the foothills of the Brooks Range, Alaska. Maximum assimilation capacities on a leaf area basis ranged from 20.3 μmol m −2 s −1 for the forb, Bistorta plumosa , to 6.0 μmol m −2 s −1 for the ever...
