Figure 5

Proportions of range overlap between species calculated using distributions estimated by convex-hull polygons. Comparisons which involve overlapping ranges (i.e. all non-zero values) are indicated in bold; a value of 1 indicates comparisons in which the range of the more narrowly-distributed species is completely embedded within that of the species with the larger range. Species names surrounded by the boxes belong to clade B of the ‘core Macowania clade’.
