P-values, calculated using 10,000 permutations of the dataset, are given below the diagonal. All of the F _st values were significant at P<0.05, except for that between Anchorage North and Trolval. After table-wide Bonferroni correction for multiple statistical tests, F _st the comparison between Rothera Point and Leonie Island also became non-significant.
