"Karyotypes of european species of radix (Gastropoda: Pulmonata: Lymnaeidae) and their relevance to species distinction in the genus"^^ . "Karyotypes of Radix auricularia (Linnaeus, 1758) and three disputable taxa considered by\r\ndifferent authors as distinct species or assigned as forms of Radix peregra (Muller, 1774),\r\nsensu lato - R. labiata (Rossmassler, 1835), R. balthica (Linnaeus, 1758), and R. ampla\r\n(Hartmann, 1821) - were studied with preparations obtained from gonad tissues by the airdrying\r\nmethod. The studied taxa have the same diploid number (2n = 34), but are characterized\r\nby different morphology of some chromosome pairs. In particular, R. labiata (traditionally\r\nidentified as R. peregra, s. s.) and R. balthica (= R. ovata in traditional understanding) differ\r\nin the number of subtelocentric chromosomes (1 and 5, respectively), species status of\r\nthese taxa being also supported by pronounced differences in centomeric indexes of chromosome\r\npairs 4 and 16. Species distinctness of R. ampla is supported by differences in\r\nthree chromosome pairs, and karyological similarity between this taxon and R. balthica is\r\nalso noted. FN values varied among the studied taxa from 56 in R. ampla to 66 in R. labiata.\r\nThe known karyological characters are traced on phylogenetic trees suggested by recent\r\nmolecular reconstructions. This study demonstrates that karyology can be an effective tool\r\nfor aiding taxonomic distinctions of historically problematic groups of molluscs."^^ . "2003" . . "45" . "1" . .
