Fig. 1. Active/total fungal biomass and active/total microbial biomass in artificial burrows not lined with corn leaf litter (ARTF); control soil (CTRL); artificial burrows lined with corn leaf litter (LEAF); and L. terrestris burrows (WORM) treatments as a function of incubation time. Bars represent one standard deviation (n = 3). Asterisks indicate dates that the active/total ratios are significantly higher in WORM soil than in any other treatment (* is for P < 0.05, ** is for P < 0.01). On Week 7, the active/total microbial biomass ratios for both LEAF and WORM soil were higher than for CTRL and ARTF.
