Table S4 : Marginal r2 values for mixed-effects models with clay concentration, pH, or fungi:bacteria as the sole fixed effect and soil pit as a random effect on EE activities normalized by microbial biomass (MB) or soil organic carbon (SOC) concentration. Key: α-glucosidase (AG), β-glucosidase (BG), cellobiohydrolase (CB), β-xylosidase (BX), N-acetylglucosamine (NAG), leucine aminopeptidase (LAP), and phosphatase (AP). Bolded values represent a significant (α = 0.05) effect and +/- signifies the direction of the effect (Clay: n = 143, pH: n = 143, fungi:bacteria: n = 178).
