Abstract

Samples of the fresh-water crustacean Asellus aquaticus were taken from three sites in the River Trent basin, subjected to different amounts of lead pollution. The survival rate of large and small animals were compared experimentally in a series of different concentrations of lead. Differential survival was recorded between the size classes and the sites that could be explained in terms of genetic adaptation. The significance of the results is discussed in terms of adaptation to environmental pollution.
