Notes.
Where data did not meet assumptions of parametric tests, permanova models were performed as indicated by †.
Bold p values indicate statistical significance (α = 0.05). ’m’: Marginal R2 value, the proportion of variance explained by fixed factors alone. ’c’: Conditional R2 value, the proportion of variance explained by both fixed and random factors combined.
