Spatial genetic structure in a metapopulation of the land snail Cepaea nemoralis (Gastropoda: Helicidae).

abstract：:In species that form dense populations, major disturbance events are expected to increase the chance of establishment for immigrant lineages. Real-time tests of the impact of disturbance on patterns of genetic structure are, however, scarce. Central to testing these concepts is determining the pool of potential immigr...
