Ten new microsatellite loci for analysis of genetic diversity in isolated populations of the Alpine land snail Cylindrus obtusus

Arthofer W., Cadahía L. and Kruckenhauser L.

In this study we characterized 10 polymorphic microsatellite markers for the land snail Cylindrus obtusus, an endemism of the Austrian Alps with a distribution in isolated populations above approximately 1600 m. The microsatellite loci were analyzed in 44 individuals from two populations. Number of alleles per locus ranged between two and eight. Observed heterozygosity ranged between 0.00 and 1.00, and expected heterozygosity between 0.09 and 0.72. No significant linkage disequilibrium was found between pairs of loci. One of the sampled populations (Dachstein) showed no deviation from Hardy–Weinberg equilibrium and no presence of null alleles, whereas the other one (Schneeberg) did. These diverging results probably reflect differences in population structure rather than characteristics of the microsatellite loci and underline the usefulness of these markers for studying genetic diversity, population structure and differentiation in C. obtusus.
