Genetic differentiation through dispersal and isolation in two freshwater fish species from coastal basins of Northeastern Brazil Neotropical Ichthyology
Abreu,João Marcelo S.; Waltz,Brandon T.; Albert,James S.; Piorski,Nivaldo M..
Abstract The coastal basins in Northeastern Brazil used in this study make up two different ecoregions for freshwater fishes (Amazonas estuary and coastal drainages, and Parnaiba) and two areas of endemism for Characiformes (Maranhão and Parnaíba), and exhibits a diversified yet poorly explored freshwater fish fauna. The population structure and biogeography of two migratory freshwater fish species that are commercially exploited from Maranhão and Parnaíba regions were herein analyzed. Molecular sequence data and statistical analyses were used to estimate haplotypes networks and lineage divergence times and correlated with hydrographic history of drainage and paleodrainages of the region. A total of 171 sequences was produced for both species, Schizodon...
