PERMANCOVA+ results for epibiota species data (2007–2010).

Note:* indicates that the random nested season effect is analysed as a fixed effect in the simplified model. In both models all factor * covariate interactions were non-significant.Type I SS PERMANCOVA+ results for epibiota assemblage data from 2007–2010; n = 564 for the Sargassum treatment and n = 571 for the Control treatment over 4 years with 3 seasons per year. Pdisp gives P values for homogeneity of dispersion (PERMDISP) tests for main effects, Psimp gives the P values for a simplified model excluding the non-significant effect of Year and its interactions with other main effects.
