Figure 3 Bayesian inference tree reconstructed from cytochrome b in Fossorial morphotype does not make a species in water voles

Figure 3 Bayesian inference tree reconstructed from cytochrome b sequences of water vole ArVicola. The tree is rooted with 11 species of Arvicolinae: MicrotUS aGreStiS, M. cabrerae, M. SUbterraneUS, M. lUSitanicUS, M. dUodecimcoStatUS, M. arValiS, Neodon irene, N. leUcUrUS, ChionomYS niValiS, C. roberti, and C. GUd. The branching pattern and branch lengths follow the Bayesian analysis, whereas the first and second numbers on the branches correspond to posterior probability values and bootstrap support in the maximum likelihood tree analyses, respectively. Symbols for morphotypes (∆ – fossorial; □ – aquatic) correspond to those in Figure 1 and Table 1.
