Table 2 Mean of squares, pseudo-F ratios (F), significance levels (P-Values), and components of variation (COV) for a series of PERMANOVA tests, employing the Bray–Curtis similarity matrix derived from the mean percentage weight contributions of the various prey taxa to the stomach contents of Pacific Cod (Gadus macrocephalus). Bold letters indicate statistical significance at P = 0.05.

From: Combined stomach content and stable isotope analyses revealed variations in trophic ecology of pacific cod in the east sea
