From: Canopy gap impacts on soil organic carbon and nutrient dynamic: a meta-analysis
Relationships of mean annual temperature (MAT, a-e), mean annual precipitation (MAP, f–h), and mean ultraviolet radiation (UV radiation, i-o) with response ratios (RR) of SOC content and nutrient availability. Fitted regressions and corresponding levels of significance are presented. Corg, soil organic carbon; Nt, total nitrogen; NH4+, ammonium; available P, available phosphorus; Hy-EEAs, hydrolases-extracellular enzymes activities; Ox-EEAs, oxidoreductases-extracellular enzymes activities; Cmic, microbial biomass carbon; Cmic:Nmic, the ratio of microbial biomass carbon to microbial biomass nitrogen
