Abstract

Both human-mediated introductions and climatic changes may promote the settlement of species in new areas outside of their natural geographical range. To investigate the settlement of recently established populations of the neogastropod Cyclope neritea, we developed eight microsatellite markers. Their usefulness was studied in two native populations previously found to be monomorphic with mitochondrial markers. The eight loci were found to be polymorphic in both populations, with two to 18 alleles per locus. This result shows promise for these loci in studies of recently founded populations of C. neritea.
