FIGURE 18. Comparisons of morphometric and thalweg-constrained geographic distances among subspecies pairs of G. carapo. Similar subspecies pairs highlighted in shades of green; differences in shades of orange. A. Number of characters with no significant differences using caliper-based morphometrics against thalweg-constrained distances via the Shield pathways. B. Procrustes distances from geometric morphometrics against thalweg-constrained distances via the Sub-Andean pathways.
