Fig. S8 . Effects of nitrogen addition and mowing on the biomass
resistance (B rst) and recovery (B rc) of four other
dominant species (C. duriuscula, C. squarrosa , B.
scorzonerifolium and S.baicalensis ) experiencing
drought in three consecutive growing seasons. Bars indicate means ± SE.
Different letters above or below the bars indicate significant
differences (P < 0.05) among treatments. C: control; N:
nitrogen addition; M: mowing; NM: nitrogen addition plus mowing.
