| molecular phylogenetics, vocalizations, and species limits in celeus woodpeckers (aves: picidae). | species limits and the evolutionary mechanisms that have shaped diversification of woodpeckers and allies (picidae) remain obscure, as inter and intraspecific phylogenetic relationships have yet to be comprehensively resolved for most genera. herein, we analyzed 5020 base pairs of nucleotide sequence data from the mitochondrial and nuclear genomes to reconstruct the evolutionary history of celeus woodpeckers. broad geographic sampling was employed to assess species limits in phenotypically varia ... | 2011 | 21596145 |
