Assessment of a state of population gene pools of terrestrial mollusks in conditions of influence of ore dressing combines on example Bradybaena fruticum Müll. (Gastropoda, Pullmonata)
On the basis of analysis of the morphological and genetical variability revealed by a method of gel-electrophoresis of proteins, the state of gene pools of populations of modeling species Bradybaena fruticum (a bush snails) in conditions of influence of ore dressing combines is investigated. Authentic decrease of a level of heterozygosity and decrease of an allelic diversification in researched bunches is fixed in сomparison with the control populations, caused, both natural factors, and factors of an anthropogenic parentage. The genetic-automatic processes in populations are considered and vectors of natural selection are defined. On the basis of calculation of effective number the forecast of time of existence of populations is given.
