From: Global ecological predictors of the soil priming effect

Apparent soil priming effects across globally distributed ecosystems. a Priming effect across major biomes. Different letters in this panel indicate significant differences among ecosystems (p = 0.007). b Histogram showing data distribution for the apparent priming effect. c Percentage of CO2 from apparent priming vs. basal soil microbial respiration rates (p = 0.50). d Histogram showing data distribution for the apparent priming vs. soil respiration rates. Number of samples in brackets (n = 86). Ecosystems are defined using major vegetation types and the Koppen classification. Number of sites is indicated in parentheses. Error bars are standard error of the mean. Source data are provided as a Source Data file
