Abstract

Comparative phylogeography is a branch of phylogeography, intended to study the effects of evolutionary history and biogeography on the distribution of genetic variation of co-distributed species. The Atlantic Forest (AF) is one of the most important and threatened biodiversity hotspots of the world characterized by having high diversity and endemism of organisms. The evolutionary history of AF is complex, however phylogeographic studies of different taxa represent an approach that can be useful for understanding the evolutionary processes that occurred within the biome. Although studies undertaken with the terrestrial biota represent considerable progress for recognition of phylogeographic patterns within this biome, studies involving the aquatic biota are still scarce. Since freshwater fishes are primarily restricted to the drainages where they occur, a strong relationship between the history of the basin and its ichthyofauna is expected, making the group an interesting model for phylogeographic studies. Until now, the few published studies on the phylogeography of the AF's ichthyofauna included only groups with very restricted distribution that did not allow to characterize a more general pattern. This project aims to produce a multilocus comparative phylogeography study to investigate, describe, and analyze the phylogeographic pattern of fish species of Characidae, one of the largest fish families widely distributed in rivers and streams along the AF. Such approach will allow to detect if there is a general pattern for the biome, if there are phylogeographic discontinuities for the rivers in the AF and if there are patterns shared with the terrestrial biota. The compilation of these data is crucial to support a more complete understanding of the evolutionary history of the AF and its conservation.
