Abstract

Significant differences between populations occur in calcium uptake during growth within one species of freshwater limpet. These are not related to environmental differences and may involve genetically determined physiological races. Such variation is significant in relation to aspects of evolution in freshwater animals and is important in assessing radionuclide contamination.
