Significant differences between time points within lakes and between lakes within time points for haplotype diversity (H; below the diagonal) and nucleotide diversity (π; above the diagonal), see Table 5 for values. Shown are those comparisons that are significant according to a pairwise one-tailed t-test, corrected for multiple comparisons by the sequential Bonferroni method. H: *p < 0.05, **p < 0.001; π: †p < 0.05, ††p < 0.001.
