Table 1.
Comparing regions defined by other clades with those defined by butterflies using V-measure scores and correlation coefficients from spatially explicit t-tests. Higher V-measure scores indicate higher congruency between regional polygons for butterflies and the focal taxon; higher correlation coefficients indicate that the boundaries of regions defined by the two taxa are closer in space.
