A Heat trees contrasting bacteria taxa abundance between healthy and Argulus foliaceus infected fish under 12:12 LD (top) or 24:0 LD (bottom) photoperiods. The colour of each taxon represents the log-2 ratio of median proportions of reads. Taxa with significant differences are labelled, determined using a Wilcox rank-sum test followed by a Benjamini-Hochberg (FDR) correction for multiple comparisons. Taxa coloured cyan are enriched in healthy fish and those coloured orange are enriched in infected fish. Node size is relative to prevalence in all samples. B Taxa with significantly different abundances (FDR-corrected p value < 0.05) between healthy and A. foliaceus infected fish under 12:12 LD (top) or 24:0 LD (bottom) photoperiods, determined via DESeq2 analyses. Taxa above the dotted line are significantly more abundant in infected fish; below the line are more abundant in healthy fish
