^aR² values, P values, and adjusted P values for pairwise comparisons of community composition (beta diversity) between the different species or ecotypes using PERMANOVA. The tests are based on Bray-Curtis dissimilarity calculated from order-level, normalized sequence counts. P values are adjusted for multiple testing by the Holm method. Significant differences (P < 0.05) are indicated in bold. (Genus- and species-level results can be found in Table S6.)

^bNEAC, Northeast Arctic cod; NCC, Norwegian coastal cod; PC, poor cod; NP, Norway pout; NSP, northern silvery pout.
