Figure 3.

(A) Bayesian phylogram (50% majority rule consensus tree) for Martes spp. based on a 646-bp “mtDNA II” fragment. A sample of Martes flavigula was used as outgroup. Node statistical support is reported as nodal posterior probabilities. Rectangles refer to phylogroups identified by Ruiz-González et al. [15] (see Figure 1 for their codes), plus the novel Sicilian phylogroup (SIC). NA, Geographical origin of the samples not available. Square brackets group the samples according to the current taxonomy of the genus. Our novel sequences are reported in bold. The three-letter country codes shown in the figure are reported according to the “ISO 3166-1 alpha-3 standard”. (B) Median-joining haplotype network based on the “mtDNA II” dataset of Martes martes. Dashes indicate substitutions steps. Each circle represents a haplotype, and its size is proportional to its frequency. Colours refer to phylogroups shown in (A).
