Table S3 : Marginal r2 values for
mixed-effects models with soil microbial biomass (MB), soil organic
carbon (SOC) concentration, clay concentration, pH, or fungi:bacteria as
the sole fixed effect, and soil pit as a random effect on EE activities
(kg-1 soil) in surface (< 20 cm) and
subsoils (> 20 cm). Key: α-glucosidase (AG), β-glucosidase
(BG), cellobiohydrolase (CB), β-xylosidase (BX), N-acetylglucosamine
(NAG), leucine aminopeptidase (LAP), acid phosphatase (AP), sum of
C-degrading enzymes (Csum = AG + BG + CB + BX), and sum
of nitrogen-mineralizing enzymes (Nsum = NAG + LAP).
Bolded values represent a significant (α = 0.05) effect and +/-
signifies the direction of the effect (surface soil MB, SOC,
fungi:bacteria: n = 38, subsoil MB, SOC, fungi:bacteria: n = 140,
surface soil clay & pH: n = 29, subsoil clay and pH: n = 114).
