Phylogenetic analyses of the genera Pipra, Lepidothrix and Dixiphia (Pipridae, Passeriformes) using partial cytochrome b and 16S mtDNA genes

Description
Summary:The piprids (manakins) are small‐bodied Neotropical birds characterized by sexual dimorphism of the plumage and elaborate courtship rituals. The phylogenetic relationships of some of piprid genera, in particular Pipra, are not well defined. Recently, Pipra was divided into three distinct groups, and the recognition of two new genera — Lepidothrix and Dixiphia— was suggested, based on the characteristic of the syringial morphology. In the present study, we analyse the phylogenetic relationships among these genera on the basis of data from the mitochondrial genes rRNA 16S and cytochrome b. Bayesian Inference (BI), Maximum Parsimony (MP) and Maximum Likelihood (ML) methods of analyses produced phylogenetic trees with very similar topologies with regard to the groupings formed by the species representing the three genera. These results indicate that the genera Pipra, Lepidothrix and Dixiphia do not constitute a single monophyletic clade, and support the current hypothesis of polyphyletism for the former representatives of the genus Pipra. However, the topologies presented do not coincide exactly with the phylogeny suggested by the morphological data with regard to the relationship between these three groups and the remaining piprid genera analysed here, emphasizing the need for further studies of this group of birds. The agreement between the molecular data presented here and the biogeographical information available for some of the species analysed appears to confirm the potential of using segments of the mitochondrial genome for the study of phylogeographical patterns in this group of organisms.
