The influence of WSR on α-diversity (Shannon’s diversity index) for bacterial (A) and fungal (B) communities within each site, year, and compartment. Horizontal bars in boxes are medians; upper and lower box edges are the 75th and 25th quartiles, respectively; and whiskers are 1.5-fold the interquartile range. Based on Wilcoxon rank-sum test, significant differences between treatments within a compartment are indicated with “*” (p < 0.05) or “**” (p < 0.01).
