Phylogeography, Historical Population Demography, and Climatic Modeling of Two Bird Species Uncover Past Connections Between Amazonia and the Atlantic Forest.

We combined mitochondrial DNA sequence data and paleoclimatic distribution models to document phylogeographic patterns and investigate the historical demography of two manakins, and , as well as to explore connections between Amazonia and the Atlantic Forest. ND2 sequences of (75 individuals, 24 sites) and (196, 77) were used in Bayesian inference and maximum likelihood analyses. We estimated mitochondrial nucleotide diversity, employed statistical tests to detect deviations from neutral evolution and constant population sizes, and used species distribution modeling to infer the location of suitable climate for both species under present-day conditions, the Last Glacial Maximum (LGM), and the Last Interglacial Maximum (LIG).
