    Analysis of genetic variability in populations of a terrestrial snail Chondrula tridens MÜll. (Gastropoda, Pulmonata), Based on the RAPD and ISSR Markers

    In this study we examined evolutionary processes in the populations of small mobile animal species, the terrestrial mollusks Chondrula tridens Müll. (Ch. tridens) in the urbanized landscape. We applied PCR methodology, using the RAPD and ISSR DNA markers, to define the genetic structure in the Ch. tridens populations, inhabiting the Mid-Russian Upland. Analysis of the obtained DNA patterns uncovered the presence of both polymorphic and monomorphic alleles. Based on this data, we defined the levels of genetic variability in the studied Ch. tridens populations, and determined the factors affecting formation of the population’s gene pool in this species. We present our conclusions on the genome structure and gene pool distri-bution in the populations of the Ch. tridens in the urbanized landscap

    Based on DNA markers (RAPD and ISSR), the state of gene pools of nineteen populations of the specially protected relict Helicopsis striata (Mollusca, Gastropoda, Pulmonata) species in conditions of the Central Russian Upland south was studie

    Temporal dynamics of the genetic structure and effective size of Bradybaena fruticum müll : Mollusca, Gastropoda, Pulmonata : Populations in the south of the central Russian upland

    Studies on the gene pool structure in ten populations of the bush snail Bradybaena fruticum Müll. inhabiting the southern Central Russian Upland were performed with a time interval of 14 years, in 1996 and 2010. Significant changes were revealed in allele frequencies and the level of genetic diversity. Using the temporal method (Krimbas and Tsakas, 1971; Nei and Tajima, 1981), the effective population size was calculated for the studied groups of mollusks. Specific features of the metapopulation structure of Br. fruticum in an urbanized landscape are discussedyesBelgorod State National Research Universit

    Genetic structure analysis of the alien mollusk Stenomphalia ravergiensis (Mollusca, Gastropoda, Pulmonata) population in Belgorod (Russia)

    Get PDF
    Gel electrophoretic analysis of allozymes was used to study the genetic structure of the population of the alien mollusk Stenomphalia ravergiensis that inhabits urbanized landscapes in the town of Belgorod (Russia). A high genetic variability level and low values of inbreeding coefficient were characteristic of most colonie
