“…Given the current distribution of the lineages and the results of the biogeographic analysis, the Japurá River probably acted as a primary barrier for the divergence of lineages A and B, which occur on the opposite banks of this river, and separated approximately 0.2 mya (considering the estimate of the species tree). Part of the bird diversity of the western Amazon basin is composed of relatively young, and closely related taxa, which are separated by the rivers of the Amazon basin, indicating a limited degree of dispersal in these lineages (Crouch, Capurucho, Hackett, & Bates, 2019), which is consistent with the divergence times found in the present study among the L. coronata lineages. The divergence time of the A and B lineages defined by the species tree indicates that these two lineages persisted within their respective centres of endemism throughout the last two major glacial cycles (including the Last Glacial Cycle, which occurred ~23,000 years ago).…”

We used molecular tools and a multilocus approach to investigate the phylogeography of Lepidothrix coronata across most of its ample range. We sequenced six DNA fragments to produce phylogenies, molecular dating estimates, analyses of the dynamics of the demographic history of the species and a biogeographic analysis to estimate the events and changes in the ancestral distribution of the species. The results indicated the presence of four well‐established lineages, with high levels of divergence. These lineages are delineated by well‐defined geographic barriers, with one lineage, restricted to the west of the Andes, being the first to diverge from the complex. The other three lineages are exclusive to the Amazonian distribution of the species, with two being found north of the Amazon River, and the third, south of the Amazon. Some of the relationships found between these lineages were distinct from those described in previous studies. Important disagreements were found between the mtDNA phylogeny and that of the multilocus analysis, in relation to the lineages located to the west of the Andes. We propose that past introgression events may have influenced shifts in the relationships between lineages, despite the fact that the groups were well defined in both the phylogenies. The biogeographic analysis indicates that the lineages arose through successive vicariance events, which had a primary role in the diversification of the group. Two or three genetically structured subclades were also found within each Amazonian lineage, although these subclades are not isolated by an obvious geographic barrier.

“…If dispersal is the main driver of current patterns of diversity, the phylogenetic diversity of current communities should have no clear spatial relationship with landscape history 25 . However, the results of the models presented here show that stable or unstable regions along the history of Amazonian landscape largely coincide with areas that have different patterns of passerine community phylogenetic structure 23 (Fig. 3).…”

“…The literature about how current Amazonian communities are shaped is marked by the debate about the relative contributions of historical processes (biogeographical and climatic) 23 versus differential dispersal 24,25 not directly related to landscape features or its evolution. If dispersal is the main driver of current patterns of diversity, the phylogenetic diversity of current communities should have no clear spatial relationship with landscape history 25 .…”

“…A comparable result, but including fewer Amazonian localities was found for trees 24 and snakes 26 , strongly suggesting a non-random relationship between Earth history, community assembly and diversity distribution through time.

The Amazonian landscape evolution is the result of the combined effect of Andean tectonism, climate and the Earth’s interior dynamics. To reconstruct the landscape evolution and its influence on paleoenvironmental variations within Amazonia since the Oligocene, we conducted numerical experiments that incorporate different surface and geodynamic processes, reproducing many paleogeographic features as inferred from the sedimentary record. We show that the evolution of the drainage pattern gradually reduced the area of sedimentation derived from the Guiana and Brazilian shields while expanded the Andean derived deposits during the Miocene, affecting the nutrient availability. First order biotic habitats were inferred from these paleogeographical reconstructions, showing an eastward expansion of várzea and terra firme forests and consequent retraction of igapó forests, with a millennial-scale reconfiguration of a mosaic of habitats in the lowlands. We conclude that this dynamism probably guided the observed patterns of speciation in the most biodiverse biome on Earth.

“…In particular, we suggest that some of the large Amazonian rivers have experienced avulsions or river capture events that have changed the positions or tributary arrangements of the rivers much more recently than is generally thought. Such dynamism has been mentioned as a possibly relevant factor in Amazonian biogeography, although without specific scenarios (Albert et al 2018, Crouch et al 2019, Dagosta et al 2017.…”

Highlights • The river network in central Amazonia has changed radically during the last 100 ky. The river Japurá (Caquetá) disconnected from the Rio Negro and became a tributary of the Amazon only about 1000 years ago, and the upper reaches of both the Juruá and the Madeira have been tributaries of the Purus. • Shifting tributary arrangements create a dynamic biogeographic landscape where dispersal barriers and dispersal routes for both terrestrial and aquatic organisms are more ephemeral than has been thought. • The Madeira approximately follows a geological boundary, so species distributional limits might depend either on the riverine barrier effect or on habitat selection. Furthermore, the upper Madeira formerly flowed into the Purus, so the lower Madeira has a shorter history as a large river. • We provide a map of apparent former positions of four large central Amazonian rivers to encourage the testing of dynamic biogeographical hypotheses.
