Limited population genetic variation but pronounced seascape genetic structuring in populations of the Mediterranean mussel () from the eastern Adriatic Sea.

Population genetic analysis of variation at five neutral microsatellite loci for Mediterranean mussels () from 18 sites along the eastern Adriatic Sea revealed little or no spatial variation. In contrast, seascape genetics analysis revealed a pronounced locus-specific gradient in allelic and genotypic frequencies across the study region. At a sixth locus, MGE7, the frequencies of two alleles, MGE7 and MGE7, were strongly associated, negatively and positively, respectively, with a single environmental variable - minimum salinity (minSAL).
