Results of PERMANOVA main test for PiCRUSt functional predictions.

Source of variation	Pseudo-F	P (perm)	PERMDISP (P)
Nutrients	2.2561	0.117
Seaweeds	3.4634	0.016	0.007
Nu × Se	0.75775	0.595

PERMANOVA values were calculated after square-root transformation and Bray–Curtis distances calculation for predicted functional profiles. H₀: there are no differences in the distribution of predicted functions for the different treatments, H₀ rejected if: p < 0.05. Factors abbreviations: Nu, Nutrients; Se, Seaweeds, Bold face values are significant at P < 0.05, P-values based on 999 permutations.
