From: Canopy gap impacts on soil organic carbon and nutrient dynamic: a meta-analysis
Response of SOC content and nutrient availability to canopy gap creation for three categorical variables, including gap age and size. Values are mean effect size (×100%) ± 95% confidence intervals (CI). The vertical line is drawn at lnRR=0. The number of observations is within the parentheses. Corg, soil organic carbon; Nt, total nitrogen; Pt, total phosphorus; C:N, the ratio of soil organic carbon to total nitrogen; NH4+, ammonium; NO3-, nitrate; available phosphorus, available P; Hy-EEAs, hydrolases-extracellular enzymes activities; Ox-EEAs, oxidoreductases-extracellular enzymes activities; Cmic, microbial biomass carbon; Nmic, microbial biomass nitrogen; Pmic microbial biomass phosphorus; Cmic:Nmic, the ratio of microbial biomass carbon to microbial biomass nitrogen
