Final matrices: SNPs and mtDNA of Synallaxis albigularis / Mazaria propinqua

Differentiated habitat use can predict the diversity and genetic structure of Amazonian birds. Making this link between the intrinsic characteristics of organisms and the patterns of genetic diversity can provide us with insights into the evolutionary processes that act on species and also on the history of environments. About 15% of non-aquatic birds in the Amazon are restricted to river-created habitats, and have different levels of habitat affinity. In this study we investigated the evolutionary history of Synallaxis albigularis and Mazaria propinqua, two morphologically very similar species, which occur in the initial successional vegetation along the floodplains in western and central Amazonia, co-occurring along the Solimões River. Although sympatric, they are not syntopic, M. propinqua occurs predominantly in river islands of white water rivers, while S. albigularis occurs along alluvial plains on the river banks, using more diverse types of habitat. We used occurrence data from ...
