ABSTRACT
Molecular markers are important tools in determining parentage, gene flow, and the genetic structure of species. In the case of rare, endemic, and/or threatened species, these markers can be used to understand key ecological questions and support conservation actions. We developed seven microsatellite markers for the only bird endemic to the Restinga ecosystem. Microsatellite loci were isolated from a library that was based on 10 individuals (six males and four females). Primers were tested in 107 individuals of the same population. The number of alleles per locus ranged from 4 to 19, and the observed and expected heterozygosity varied from 0.15 to 0.84 and from 0.60 to 0.89, respectively. We expect that the polymorphic microsatellite loci we describe will be useful for other studies, particularly in the Tropics.
