Supplementary Table I. Two way PERMANOVA tests of log density for all taxa except those with very low density. Pseudo-f values are supplied, with the number of unique permutations in parentheses. * denotes p <0.05, ** denotes p < 0.005. Where the main test identified a significant interaction among treatments and days, treatment contrasts were conducted separately for each day. No contrasts were conducted for Keratella spp. because the main treatment test was not significant.
