Microspatial structure of population gene pool in the land snail Helicopsis striata (Pulmonata, Hygromiidae) in the conditions of the Southern Mid-Russian Upland

Abstract

Microspatial differentiation of the population gene pools of the terrestrial mollusk Helicopsis striata (Muller, 1774) is revealed for various conditions of the Southern Mid-Russian Upland, which is caused by the fragmentation of habitats and differences in the intensity of the gene flow between demes. The spatial differentiation of H. striata, due to the special features of its biology, is the highest among other terrestrial mollusks of the studied region
