Abstract

The Amazon is one of the most diverse biomes on the planet. Despite the importance of this ecosystem, very little is still known about the ecological and evolutionary processes involved in the diversification, maintenance and distribution of species in this region. Given the extension of this biome, study cases of organisms with disjunct geographical distributions are critical for a better understanding of the history of this system. The genus Pagamea (Rubiaceae) includes several species that are restricted to white-sand soils from the Amazon Basin (campinas and campinaranas), representing an excellent model for studies on the genetic structure and phylogeography in this region. In order to elucidate the phylogeographical history of P. coriacea, we will use Restriction-site Associated DNA sequencing (RAD-Seq) to identify a set of informative SNP loci. Considering that P. coriacea has a disjunct distribution, with populations on either side of the Amazon wide rivers, we will test the hypothesis that wide rivers are biogeographic barriers to gene flow, with the genetic differentiation among populations being enhanced by the geographic isolation of the campinaranas. Furthermore, we will also estimate the pattern and time of divergence among populations of P. coriacea in order to better understand their evolutionary history. This project is linked to the Thematic Project "Structure and Evolution of the Amazonian Biota and its environment: An Integrative Approach" (FAPESP: 2012/50260-6).
