Karyological Features of the Genus Planorbarius (Gastropoda, Pulmonata, Bulinidae) of the Ukranian Fauna [PDF]

open access: yes, 2007
The absence of significant distinctions between the species of the genus Planorbarius in the narrow sense (P. corneus, P. banaticus, P. purpura, and P. grandis) has been established. All investigated species had identical chromosomal formulas (2n= 30 m +
