Principal coordinates analysis (PCoA) revealing the distribution of soil and fauna bacterial communities using the weighted unifrac distance based on the relative abundance of bacterial OTUs (a) and the unweighted unifrac distance based on the presence/absence of bacterial OTUs (b). Different shapes and colors represented different types of samples. The variation explained by the PCoA axes is listed in parentheses. Significant analysis of variance used distance matrices (PERMANOVA) via Adonis test (999 permutations). Boxplots presenting the distance of bacterial communities between each soil fauna group and soil samples (c weighted unifrac and d unweighted unifrac), which reflecting the similarity of bacterial community between treatments. Significance of results was evaluated using pairwise PERMANOVA and labeled using different letters (significant level P < 0.05). The “n” indicated the number of distance between each soil fauna group and soil. Centre line, median; box limits, first and third quartiles; whiskers, 1.5 × interquartile range
