Fig. 2

Decomposition of changes in plant functional traits using CWMs in a typical and a meadow steppe. Black bars represent total variation. The space between the top of the column and the bar corresponds to the covariation effects; positive covariation implies that the bar is above the column, and negative covariation indicates that the bar crosses the column. N, N addition; D, drought; N*D, interaction between N addition and drought; Res., Residual; Total variation, interspecific variation + interspecific variation + covariation. Significance values are indicated by an asterisk above each column. The positioning of an asterisk within the -/-/- graphic represents the significance of the interspecific variation/intraspecific variation/total variation, respectively. -, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001
