Genetical structure of populations of modelling species of terrestrial mollusks in conditions of the urbanized landscape on example Сhondrula tridens Müll (Gastropoda, Pulmonata)
On the basis of the analysis of the morphological and genetical variability revealed by a method of gel-electrophoresis of proteins in PAAG, the state of gene pools of populations of modeling species Сhondrula tridens Müll (threedens snail) in conditions of the urbanized forest-steppe landscape of the south of Mid-Russia Upland is investigated. In the majority of the investigated bunches authentic decrease of a level of heterozygosity and the decrease of an allelic diversification caused, both is fixed by natural historical factors, and factors of an anthropogenic parentage. The genetic-automatic processes in populations are considered and vectors of natural selection are defined. Calculation of effective number of researched bunches is spent.
