Integrating phylogenetic and population genetic analyses of multiple loci to test species divergence hypotheses in Passerina buntings.

ABSTRACT: Phylogenetic and population genetic analyses of DNA sequence data from 10 nuclear loci were used to test species divergence hypotheses within Passerina buntings, with special focus on a strongly supported, but controversial, sister relationship between Passerina amoena and P. caerulea inferred from a previous mitochondrial study. Here, a maximum-likelihood analysis of a concatenated 10-locus data set, as well as minimize-deep-coalescences and maximum-likelihood analyses of the locus-specific gene trees, recovered the traditional sister relationship between P. amoena and P. cyanea. In addition, a more recent divergence time estimate between P. amoena and P. cyanea than between P. amoena and P. caerulea provided evidence for the traditional sister relationship. These results provide a compel
