Species-Specific Responses to Paleoclimatic Changes and Landscape Barriers Drive Contrasting Phylogeography of Co-Distributed Lemur Species in Northeastern Madagascar.

ABSTRACT: River barriers have long played a central role in diversification models of tropical regions, including the exceptionally biodiverse island Madagascar. Although their role is best understood by integrating additional factors such as elevation and the ecological niche of a species, empirical studies integrating these variables remain rare. We used restriction site-associated DNA sequencing to assess the combined effect of rivers, topography, climate and forest cover on the distributions and diversity of four Microcebus and two Avahi species (Primates, Lemuriformes) in northeastern Madagascar. We inferred population structure, gene flow and genetic diversity, and assessed the association of these ecogeographic variables and genetic differentiation using isolation-by-resistance models.
