FIGURE 5

The ratio of OTU numbers revealed in (A) wood and (B) CWD-influenced litter samples to CWD-uninfluenced litter samples in the areas with different levels of pollution. Different letters indicate statistically significant differences of mean values between areas, revealed with Tukey’s test (p < 0.05, n = 29; Supplementary Table 6). A few outliers in Mucoromycota are not shown due to clipping of the y-axis at the top for readability (however, the analysis was performed on the full dataset). OTU, operational taxonomic unit; CWD, coarse woody debris.
