Table 1 The average coverage of three shrub (Dryas octopetala var. asiatica, Vaccinium uliginosum and Rhododendron confertissimum) species in the warming open-top chambers and the control plots investigated before and after seven years’ warming treatment (unit: %; n=8). Different lowercase letters indicated significant difference in coverage among years. The statistical results of the effects of warming on coverage was shown by P value for each species (** P < 0.01, *** P ≤ 0.001, ns P > 0.05.)
