Figure 4 in Delimiting phylogeographic diversity in the genomic era: application to an Iberian endemic frog

Figure 4. Comparison of body size in common frogs from northwestern Spain. (A) Violin plots showing variation in SVL among 1947 males of R. p. parvipalmata (T1, red), R. p. asturiensis (T2, orange), and R. temporaria from nearby Cantabria (T6, blue). (B) Neighbour-joining tree of pairwise size differences among these three lineages. Photo: T1 frog from La Garganta (credit: J. Ambu).
