Chemical composition of shells of Cepaea vindobonensis (Férussac) from sites with carbonate and carbonate-silica bedrock in central and south-eastern Poland and from alluvial deposits of the Vistula River indicates a relation between the chemism of the environment in which the species occurs and the chemical composition of the shells. The ability to accumulate heavy metals in the shell of C. vindobonensis...
61 sequences of cytochrome oxidase subunit 1 (COI), 570 bp long, from Central Europe (8), Slovenia (2), and from the Balkans (51: 6 from, Romania, 15 from Greece, 15 from Bulgaria, 6 from Serbia, and 9 from Montenegro), 33 of them new, together with 61 sequences of the ribosomal 18S, 450 bp long, all of them new, were analysed to infer the pattern of radiation of Bythinella in the Balkans. Thirty...
