Meta-analysis of the impacts of global change factors on soil microbial diversity and functionality

摘要

Response ratio (natural logarithm-transformed ratio of treatment to control, RR) of microbial alpha diversity (richness and Shannon index). RR of microbial beta diversity. RR of microbial community structure. Weighted means and their 95% confidence intervals of RRs are given. The numbers at the right side of the confidence intervals represent the sample sizes. W warming, eCO carbon-dioxide enrichment, PPT− decreased precipitation, PPT+ increased precipitation, P phosphorous addition, N nitrogen addition, LUC land-use change, W × eCO warming plus carbon-dioxide enrichment, N × PPT+ nitrogen addition plus increased precipitation, N × P nitrogen plus phosphorous addition, N × P × K nitrogen plus phosphorous plus potassium addition. Source data are provided as a Source Data file.
