Morphogenetic analysis of Helix pomatia L. (Pulmonata, Helicidae) populations from south-eastern and eastern parts of the modern area

Abstract

Based on the analysis of the morphological and genetic variability detected by the method of the protein gel electrophoresis in PAAG, the gene pool state of twelve adventive Helix pomatia L. grape snail populations under the conditions of urbanized landscapes of south-eastern and eastern parts of the modern area. According to the data obtained, most of the studied populations of this mollusk are in a satisfactory state. This is illustrated by the large values of their efficient numbers, the high level of heterozygosity, and decreased inbreeding. The structure of the population gene pools of the grape snail in the researched region is determined by their origin, genetic-automatic processes, and microclimatic conditions of the urban environment.
