Percent changes in microbial biomass under different magnitudes (upper) and durations (lower) of N addition. a, e Microbial biomass C based on chloroform fumigation extraction analysis, b, f total phospholipid fatty acids (PLFAs), c, g fungal PLFAs, and d, h bacterial PLFAs. Error bars represent the 95% bootstrap confidence intervals that were calculated by weighted effect sizes. The responses of these variables to different magnitudes and durations of N addition are considered significant (P < 0.05) if the 95% bootstrap confidence intervals do not overlap with zero. The between-group heterogeneities (Qb) and the probabilities (P) of the effects of N addition on microbial biomass across different magnitudes and durations are shown in each panel
