Abstract: Suture zones are geographic regions encompassing multiple phylogeographic breaks and contact zones involving pairs of closely related taxa (animals and plants), regardless of whether hybridization is occurring. We provide a comprehensive characterization of avian suture zones at the species and subspecies-levels in the Pan-Amazonia region, which includes the Amazonas river basin, the east slope of the tropical Andes, the Tepuis, and other adjacent regions. We grouped avian taxa into species complexes based on their relationships as defined by phylogenetic and taxonomic studies. We identified and described 1,983 taxon turnovers across 53 different suture zones, including 534 taxon turnovers at the species-level. These include areas across rivers, mountain ranges, along Amazonian rivers' floodplains (várzea), and elsewhere in lowland Amazonia. We also performed linear regressions to evaluate the number of taxon turnovers across major Amazonian rivers throughout their entire extension, from mouth to headwater regions. We found that the number of taxon turnovers steadily decreases as we move upstream for all major rivers. By mapping suture zones, we provide crucial data for future studies and emphasize the significant role of the Neotropical region in creating and maintaining its rich biodiversity.
