An increasing number of investigations revealed that responses of populations to environmental stressors may be genetically dependent. Occurrence of genetic adaptation to high concentrations of heavy metals in Hediste diversicolor local ecotypes has also been hypothesised. Analyses of allozymic patterns are a promising tool for the genetic monitoring of environmental stressors. The aim of this study was to investigate whether the allozymic patterns of H. diversicolor could be affected by levels of contamination. Five sites were investigated: four in a polluted brackish habitat, the Pialassa lagoons, and a reference site in the Lamone estuary. Total mercury was used as a tracer of the overall level of contamination. Concentrations of mercury...
