1pH was not measured on PINE and MDRN soils because of
limited soil collected.
Table 2 : Marginal R2 values for mixed-effects
models with soil clay concentration, pH, or fungi:bacteria as the sole
fixed effect, and soil pit as a random effect on EE activity normalized
by microbial biomass (MB) or soil organic carbon (SOC) concentration in
top- (< 20 cm) and sub-soils (> 20 cm). Key:
α-glucosidase (AG), β-glucosidase (BG), cellobiohydrolase (CB),
β-xylosidase (BX), N-acetylglucosamine (NAG), leucine aminopeptidase
(LAP), and acid phosphatase (AP) activity. Bolded values represent a
significant (α = 0.05) effect and +/- signifies the direction of the
effect (surface soil: n = 29, subsoil: n = 114).
