摘要

Cerastoderma glaucum is an adequate biological model for phylogeographic and ecotoxicological studies.A study of its genetic structure in the Western Mediterranean sea was conducted using two markers types: mitochondrial and nuclear. The DNA mitochondrial marker results show a divergent population from all the other ones (Ellouza South ofTunisia).An ecotoxicological study of populations sampled from Ellouza site and two other nearby sites in the Gulf of Gabes region was carried out in order to study the adaptive response of natural populations of C. glaucum at different levels of biological organization from the individual level to the cellular and molecular ones. In parallel, two laboratory experiments were performed to clarify the mechanisms that may explain the success or failure of maintaining populations of C. glaucum. In thefirst one, industrial effluents were used and in the second we have used a pure contaminant, the cadmium. These studies experiments concerned individual and molecular levels. Different biomarkers involved in the response to different types of stress: (MT), (ABCB1) (MnSOD and CuZnSOD) (CAT) (HSP70) and (COI) were used in natural and exposed cockles.Results showed the importance of energy metabolism in response to stress whatever the used approach (in situ / Experimental) through the regulation of the expression of the COI gene.
