Figure S5 : Potential activity of α-glucosidase (AG),
β-glucosidase (BG), β-xylosidase (BX), cellobiohydrolase (CB),
N-acetylglucosaminidase (NAG), leucine aminopeptidase (LAP), and acid
phosphatase (AP) normalized by kg-1 soil organic
carbon (C) as a function of depth throughout the top meter of soil
across sites. Boxplots show the distribution of extracellular enzyme
activities at each depth and the blue line shows the best-fit loess
regression with standard error highlighted by the gray ribbon. Note:
scale of x-axis differs among enzymes.
