Superscripts indicate effect size thresholds for pairwise comparisons of ecoregion means reported in Table 6. Effect sizes were not sensitive to distance measure so results for Euclidean and flowpath distance measures were averaged within wetland classes (VC, NCO)
Effect size: Very large 1.3 ‘***’ Large 0.8 ‘**’ Medium 0.5 ‘*’ Small 0.2 ‘.’ (Cohen 1988)
