Genetic variability in microsatellite markers PEZ1, PEZ3, PEZ6, PEZ8, FHC2010, and FHC2054 from a panel recommended by the International Society for Animal Genetics has been assessed for a micropopulation of dogs of the French Bulldog breed. The number and size of alleles, the number of alleles per locus, the effective number of alleles, the polymorphism index, expected and actual heterozygosity, and Wright’s fixation index have been determined to characterize each locus investigated. Deficit of heterozygous genotypes was observed in the micropopulation investigated, which is indicative of inbreeding. The relationship between the degree of homozygosity for six microsatellite loci and the degree of inbreeding has been analyzed. The results obtained point at a trend for increase of the relative abundance of homozygous loci upon an increase in the inbreeding coefficient of individuals. 相似文献

The rare bird fauna of industrial wetlands has been studied in the forest-steppe zone of European Russia during the nesting
period. A total of 146 species have been recorded, including 40 rare species listed in the regional Red Data Books. Facts
of their nesting (in many cases, exceptional in the region) have been revealed. Evidence is presented for the significance
of industrial wetlands for the conservation and propagation of rare bird species. 相似文献

A procedure for isolating biologically active substances from Galleria mellonella using a culture of isolated giant neurons of mollusc Lymnaea stagnalis as a test-system is described. Fractions capable of activating neurites and inhibiting aggregation of neuronal cells within a range of concentrations from 1 to 30 micrograms/ml were isolated. The fractions obtained have in their chemical composition about 10.5% N, also contain P and S. They have a carbohydrate component. 相似文献
