Historical diversification of floodplain forest specialist species in the Amazon: a case study with two species of the avian genus Xiphorhynchus (Aves: Dendrocolaptidae).

Phylogeographical and population genetics methods are used to reconstruct the diversification history of two species of the genus Xiphorhynchus (Aves: Dendrocolaptidae) associated with seasonally flooded forest types in Amazonia. Sequences of the mitochondrial gene cytochrome b were assessed f...
