Figure S5: Principal coordinate analysis (PCoA) based on the Bray-Curtis distances between Mesonauta festivus gut sample 18S rRNA V4-V5 communities (n = 40) without considering the Class Actinopterygii in the Phyloseq object. Samples were colored according to their gut ID (n = 8) and the pinch types represent the blocking primers used during their amplification (n = 5). The percentage of the total variance explained by each axis is identified.
