Abstract

The application of molecular biology has been contributing substantially to the knowledge of how historical processes shaped the high and complex Amazonian biodiversity. The development of this discipline has allowed the inclusion of more evolutionary features to analytical procedures, considerably changing the methods of interpretation of genetic data. Despite some biogeographical hypotheses suggest different scenarios for the formation of the Amazonian biodiversity, it is a consensus that simultaneous events of isolation and dispersion followed by divergence, allowed the existence of syntopic distinct lineages. In this context, comparative phylogeographic studies can contribute to a better understanding on how paleoenvironmental and paleoclimatic processes led the formation of the current biodiversity. Thus, we selected three lineages (species complexes; Thamnophilus nigrocinereus/cryptoleucus, Myrmoborus lugubris, Myrmotherula assimilis) of the family Thamnophilidae as models for a comparative phylogeographic study. The selected species are restricted of flooded forests (várzea) of the Amazon River and large tributaries, an environment poorly studied in phylogeographic approaches. Phylogenetic and population genetic analyses based on empirical and Approximate Bayesian Computation estimates will be applied to generate a spatial and temporal scenario of diversification of each lineage based on data generated by target enrichment of Ultra Conserved Elements (UCE) and by Sanger sequencing of mitochondrial genes. We intend to answer the following questions: 1) How in a temporal and spatial context the diversification patterns of the three species complexes were formed? 2) Are there spatial and temporal overlaps in the diversification processes of the studied lineages? 3) Which paleoenvironmental and paleoclimatic scenarios can explain the diversification of the studied lineages?
