Abstract

Phylogeography studies have revealed the mechanisms of diversification of many organisms and can contribute greatly to the advancement of knowledge of these processes in Neotropical groups. In South America the studies of phylogeography have become more frequent, and new biogeographic patterns have been revealed, especially in Brazilian biomes such as the Atlantic Forest. In this sense phylogeographic studies of South American species can provide important information about the historical processes that were responsible for the biological diversity in this region. The objective of this project is to study the diversification of lineages and phylogeographic patterns Pitcairnia flammea (Bromeliaceae), a species adapted to rocky outcrops, known as "terrestrial islands" (inselbergs), inserted in the Atlantic Forest biome. The time of divergence of these lineagess, the demographic events that have shaped the genetic structure observed in the present and the gene flow patterns among populations will be investigated by characterizing the population genetic structure revealed by uni- and bi-parental molecular markers. This information is fundamental to the understanding of the processes that generated the species diversity in this biome, and provide support for the management and conservation of this and other species adapted to rocky outcrops.
