During years 2 and 3, ear biopsies to assess genetic relatedness and faeces to assess pollutant exposure will be removed from individual animals and related to their demographic and spatial ecology on each of the four study grids. Predicting ecotoxicological impacts of environmental contaminants on terrestrial small mammals. The ecotoxicological significance of cadmium intake and residues in terrestrial small mammals. Estimating the relatedness in a population of grey squirrels, Sciurus carolinensis, using DNA fingerprinting. DNA fingerprinting reveals high levels of genetic diversity in British populations of the introduced non-native grey squirrel, Sciurus carolinensis.
