Identification of ecological determinants of parapatry from range-breaking tests. a, b Density plots indicating the distributions of I (black) and D (light grey) values from pseudo-replicates for linear and blob range-breaking analyses, respectively; c, of I and D values obtained from randomly generated ribbons and a comparison of flanking habitats on either side of the corresponding ribbon; and d, of I and D values calculated between the two flanking regions and the ribbon in each pseudoreplicate, with the dashed line for comparison of ENMs from populations with sampling comparable to Feirana quadranus, and the solid line for ENMs from populations with sampling comparable to F. taihangnica. Vertical black and light grey lines indicate I and D values from ecological niche models predictions of F. quadranus and F. taihangnica for corresponding range-breaking analyses
