VITALITY ESTIMATION OF THE<i> CEPAEA VINDOBONENSIS</i> (MOLLUSCA, GASTROPODA, PULMONATA) ESPECIALLY PROTECTED SPECIES POPULATIONS IN THE CONDITIONS OF THE CENTRAL RUSSIAN UPLAND FOREST-STEPPE SOUTH
Gene pool condition of five populations of the Cepaea vindobonensis Fer (Austrian snail)especially protected species is studied in the Central Russian Upland south conditions and their comparison with the populations from the other regions is conducted on the basis of the morphological and genetic variability analysis that can be revealed by means of the protein gel - electrophoresis technique. Authentic decrease of the phenotypical diversity, heterozygosity level decrease and inbreeding coefficient increase caused by both the natural historical factors, and the factors of an anthropogenic origin is emphasized in a number of the researched groups. The genetic and automatic processes in the populations are considered and the natural selection vectors are determined. Calculation of the researched group effective number is conducted
