Fig. 4From: Disruption of fish gut microbiota composition and holobiont’s metabolome during a simulated Microcystis aeruginosa (Cyanobacteria) bloomModification of the gut metabolome composition associated with bacteria changes. a Principal component analysis (PCA) representing gut metabolite profiles at d28. b Relevance network analysis illustrating the most correlated metabolites (in white) and ASVs (in orange) discriminating among the five treatments. Only variables (ASVs, metabolites) with correlation values above ± 0.695 are displayed. Pearson correlations between covariate metabolites and ASVs are represented by coloured segments (blue: negative association, red: positive association)Back to article page
