Figure 5 in Delimiting phylogeographic diversity in the genomic era: application to an Iberian endemic frog

Figure 5. Comparison of body shape in common frogs from northwestern Spain. (A) PCA on 17 morphological characters (after allometric size correction) among 82 males of R. p. parvipalmata (T1, red circles), R. p. asturiensis (T2, orange circles), and R. temporaria from nearby Cantabria (T6, blue triangles); scatterplots show coordinates and circles show variable contributions on PC1–2 (top) and PC3–4 (bottom). (B) Neighbour-joining tree of multivariate pairwise differences among lineages.
