Gut adherent microbiota, discriminant analyses, and biomarkers: (A) Two-dimensional partial least squares discriminant analysis (p < 0.05) scores plot (PLS-DA) constructed using the taxonomic composition of the anterior intestine microbiota of gilthead sea bream reared at high (HD, n = 9, red dots), medium (MD, n = 9, blue dots), and low (LD, n = 9, green dots) density. Each square represents the distribution of the individual samples between the first two components in the model; (B) Linear discriminant analysis effect size analysis performed at the level of genus, representing the significant biomarkers for each group and their abundance in normalized counts.
