Local patterns of genetic variation were analysed in the land snail Helix aspersa for 32 populations sampled within a patchy agricultural landscape: the polders of the Bay of Mont-Saint-Michel (France). This investigation examined the allele frequencies at four enzymatic markers and five microsatellite loci through the genotyping of 580 individuals. A strongly significant population genetic substructuring (mean FST=0.088, P<0.001) was found at the scale of the whole polders area (3050 ha) and… CONTINUE READING
