Characterization of tri and tetra-nucleotide microsatellite loci for the freshwater snails Promenetus exacuous (Planorbidae) and Valvata tricarinata (Valvatidae) and their utility in population genetic studies

摘要

ObjectivePromenetus exacuous and Valvata tricarinata are freshwater snail species with widespread distributions throughout North America. Information regarding their genetic diversity and population connectivity are currently lacking. We utilized next generation sequencing to develop the first microsatellites for each species to investigate genetic diversity within and differentiation among populations.
