Graph showing: a) the calculated PERMANOVA power for a range of simulated effect (quantified by the adjusted coefficient of determination omega-squared (ω2) and divided by number of replicates per treatment); b) the average PERMANOVA power of panel 'a', grouped by number of replicates per treatment and into three effect size ranges: Low (0.001-0.04), Medium (0.04-0.08) and high (0.08-0.12). PERMANOVA power was calculated as the proportion of bootstrap distance matrices for which PERMANOVA P-values are less than the pre-specified threshold for type I error (0.05)
