Figure 3.

Impact of propidium monoazide (PMA) treatment on the global bacterial communities associated with the fish digesta. (a) PCoA plot representing unweighted Unifrac distances comparing the change in bacterial communities found in PMA‐treated and control samples for all five digesta replicates used in this study. (b) Boxplot presenting the median and IQR of the number of observed amplicon sequence variants (ASVs) identified in PMA‐treated and control digesta samples. The levels of significant difference are denoted by *P ≤ 0·05, **P ≤ 0·01 and ***P ≤ 0·001, following the Wilcoxon rank‐sum test.
