Figure 5 in Phylogenetic relationships and taxonomy of Altiplano populations of Biomphalaria (Gastropoda: Planorbidae): inference from a multilocus approach

Figure 5. Reconstruction of the divergence times of lineages of Biomphalaria estimated using a substitution rate of 1.6–2.2% per million years for the 16S locus. We used one sequence per population/species to generate a Bayesian tree. Numbers at nodes represent millions of years. The origin of the sequences is shown using numbers or initials (see Table 1).
