| molecular phylogeny and diversification of a widespread neotropical rainforest bird group: the buff-throated woodcreeper complex, xiphorhynchus guttatus/susurrans (aves: dendrocolaptidae). | the genus xiphorhynchus is a species rich avian group widely distributed in neotropical forests of central and south america. although recent molecular studies have improved our understanding of the spatial patterns of genetic diversity in some species of this genus, most are still poorly known, including their taxonomy. here, we address the historical diversification and phylogenetic relationships of the x. guttatus/susurrans complex, using data from two mitochondrial (cyt b and nd2) and one nu ... | 2015 | 25683049 |
