Ecological and Ecotoxicological Studies in aquatic ecosystems:
- Spatio-temporal monitoring of oysters (Crassostrea gigas) and, marine (Mytilus edulis) and brackish/freshwater (Mytilopsis leucophaeata, invasive species) mussels by considering: hydrological parameters (in collaboration with LERN, IFREMER, Port-en-Bessin), environmental pollution (in collaboration with LABEO, Caen) and biological performances (survival, bivalves’growth and quality, reproduction and stress level) (in situ studies);
- Studies on alien and potential invasive species that may induce biofouling in ecosystems under anthropogenic pressures such as marinas
- Researches about the quality of water masses and ecosystems by using active biomonitoring along the land-sea continuum (Mytilopsis leucophaeata in freshwaters and brackish environments).
- Assessments of the effects of various contaminants (pesticides, pharmaceutical residues, PCBs) on:
- embryo-larval stages and metamorphosis in marine bivalves (embryotoxicity);
- juvenile and adult bivalves by using a battery of biomarkers at different levels of organization: 1) molecular (mRNA quantification); 2) biochemical (activity of enzymes involved in detoxification and oxidant stress regulation, lipidic peroxidation, energy reserves); 3) cellular (immunotoxicity, dynamics of the lysosomal system …); individual (reprotoxicity, histopathology …) (in situ, in vivo and in vitro approaches).
These researches are conducted in the frame of programs such as:
