Figure 3. A, BP&P posterior probabilities for different prior settings corresponding to the degree of significant coalescence between reciprocally monophyletic Willisornis lineages. Θ corresponds to the population size parameter and τ to the divergence time priors at the root of the species tree. ε, α and m are different values of fine-tune parameters. B, overlapping coalescent trees for each scenario generated by BP&P.
