Isolation and characterization of eight microsatellites from the South American annual fish Austrolebias charrua
- 90 Downloads
Austrolebias charrua is an endemic annual fish of Uruguay and Brazil. Eight microsatellite markers were developed in order to clarify its population genetic structure. All of them constitute polymorphic loci. The number of observed alleles ranged from 6 to 14, the mean expected heterozygosity from 0.65 to 0.92 and the Shannon-Wiener Diversity Indices from 1.31 to 2.39. This study is the first report of microsatellites in annual killifish and they will be a helpful tool to implement conservation strategies in this endangered species.
