Assessment of the state population gene pool of specially protected species Helicopsis striata (Mollusca, Gastropoda, Pulmonata) using DNA-markers

Abstract

With the use of DNA-markers (RAPD and ISSR) the gene pool of nineteen populations of specially protected relict species Helicopsis striata (Mollusca, Gastropoda, Pulmonata) in Southern Mid-Russian Upland was studied. These results demonstrate a high degree of subdivision of populations (Фst = 0,404, Gst = 0,358) and increased levels of homozygosity in a number of groups that live in the industrial zone and the steppe habitats. The significant correlation between the level of gene flow and geographic distances between populations (R = 0,571 ± 0,052) was found, this corresponds to isolation by distance model. The values of the effective number was calculated on the basis of index units. They were significantly lower than the effective number of not protected species of snail.
