Figure 1 : Distribution of activity of α-glucosidase (AG),
β-glucosidase (BG), β-xylosidase (BX), cellobiohydrolase (CB),
N-acetylglucosaminidase (NAG), leucine aminopeptidase (LAP), and acid
phosphatase (AP) per soil mass as a function of depth throughout the top
meter of soil across sites. See Table 1 for site abbreviations.
