Abstract

Freshwater molluscs are globally critically threatened, yet little is known about their genetic diversity. We describe the isolation and characterization of the first microsatellite markers for the European swan mussel, Anodonta cygnea. Nine loci were polymorphic in a panel of 110 individuals from seven German and Estonian populations. Number of alleles ranged from 2 to 14 and heterozygosity levels ranged from 0. 021 to 0. 498 for H_o and from 0. 069 to 0. 634 for H_e. Deficiency of heterozygous genotypes was observed in six loci. The length of the microsatellite repeat motives was positively correlated with the allele numbers in the respective loci.
