The ostracode Cytherissa lacustris (Sars) has been obligatorily parthenogenetic at least since the Meso-pleistocene. Old and large populations of it from the lakes of the Salzkammergut area in Austria exhibit quite high polymorphism and quasi-Mendeli

To determine whether the Lake Ohrid population of Dendrocoelum lacteum is significantly genetically distant from the Central European populations of this species, the allozyme variation was studied. Phylogenetic analysis of isozyme electrophoretic da

Different digenic esterase clones of Cyprinotus incongruens reach maturity and die in their own time. Thus, when comparing populations, the presence or absence of clones rather than their frequency should be taken into account. There are no clear geo

Six endemic and two widely distributed species living in Lake Ohrid were studied. In general, these hermaphroditic animals displayed no signs of departure from Hardy-Weinberg equilibrium. Genetic variation in all but one of the endemic species was of

An electrophoretic survey of allozyme variation was conducted in four, highly polymorphic loci on nine populations of ostracod Candona neglecta Sars from three different environments: the profundal of post-glacial lakes, deep muddy bottom of the Balt

The copepods Limnocalanus macrurus G. O. Sars and Eucyclops serrulatus (Fisch.) and the ostracode Cytherissa lacustris (G. O. Sars), hitherto unknown on Spitsbergen, were found in Lake Rewatnet, the last species also in Lake Svartvatnet. Samples from
