*Significant warming effect on group (p < 0.05). Boldface for the Kendall’s tau rank and Spearman rank indicate significant publication bias at p < 0.05. n: the number of studies included for the meta-analysis; RR++: weighted response ratio; CI: bootstrap confidence interval; GN: gram negative bacteria; GP: gram positive bacteria.
