Avian gene trees, landscape evolution, and geology: towards a modern synthesis of Amazonian historical biogeography?

Recent studies have improved our understanding of Amazonian geological history during the late Tertiary and Quaternary, two periods regarded as critical for the recent diversification of the Amazonian avifauna. The notion that geologically older and more stable areas of Amazonia (such as the Br...

The notion that geologically older and more stable areas of Amazonia (such as the Brazilian and Guianan shields) functioned as ‘‘species-pumps’’, whereas geologically more dynamic areas (such as the western Amazonian lowlands) mostly ‘‘captured’’ part of the diversity generated nearby, was supported by a recent phylogeographic study focusing on a species complex of the genus Xiphorhynchus (Dendrocolaptidae).
