Dominant increase
In all the global change treatments except for warming only (W), the dominant species, Deschampsia cespitosa increased its relative cover compared to control plots, while subdominant and moderate species decreased their relative cover and rare species did not change. While most of the global change scenarios shared this pattern, the increase in dominance at the expense of subdominant and moderate species was the strongest in SNW plots, followed by the SW plots and then NW plots (Fig 1, Table 1).
