Fig. 3

Comparison of microbial diversity a “Chao1”, b “Faith’s Phylogenetic Diversity”, c “Shannon”, or d microbial biomass across body site (gill, skin, midgut, and hindgut). Distributions in “red” are median with interquartile range. Statistical differences determined using non-parametric testing Kruskal–Wallis test with 0.05 FDR Benjamini–Hochberg. Further testing computed for each unique body site for a variety of biological and ecological metadata categories. Metadata which is e categorical is tested using Kruskal–Wallis f whereas numeric metadata tested using Spearman correlation. Only significant associations are represented in e (Kruskal–Wallis p < 0.05) and f (Spearman p < 0.05). KW or KW stat “H” test statistic from Kruskal–Wallis test, MG midgut, HG hindgut, Faith PD Faith’s Phylogenetic Diversity metric, GI:TL gastrointestinal length to fish total length “ratio”, TL total length of fish.
