Debido a su etapa planctónica de larga vida, se espera que el gasterópodo marino Concholepas concholepas intercambie larvas a grandes distancias. Sin embargo, se han documentado discrepancias entre la dispersión esperada y la realizada en invertebrados marinos. Para investigar las relaciones entre la dispersión potencial y efectiva (es decir, el flujo de genes), desarrollamos 11 marcadores microsatélites e investigamos su utilidad analizando dos poblaciones distantes por c. 4000 kilometros. Se encontró que los 11 loci eran altamente polimórficos en ambas poblaciones, con 12 a 51 alelos según el locus. Este polimorfismo es lo suficientemente fuerte como para permitir análisis de población a escala fina, incluidos estudios de larvas y análisis de paternidad.
Because of its long-lived planktonic stage, the marine gastropod Concholepas concholepas is expected to exchange larvae over large distances. However, discrepancies between expected and realized dispersal have been documented in marine invertebrates. To investigate relationships between potential and effective (i.e. gene flow) dispersal, we developed 11 microsatellite markers and investigate their usefulness by analysing two populations distant by c. 4000 km. The 11 loci were found to be highly polymorphic in both populations, with 12–51 alleles according to the locus. This polymorphism is strong enough to allow fine-scale population analyses including larval studies and paternity analyses.
