Physiological responses of marine animals to their changing environment
These responses are studied at different levels of organisation (molecules, cells, tissues and organs, individuals, populations) and for different key functions (immune function, detoxification, respiration and filtration in Molluscs; cardiac function, sense function, aerobic metabolism and locomotion in fish) in animals submitted to the natural variations of coastal and estuarine environment (e.g. temperature, salinity, oxygen) which are submitted to the contamination to metals, POPs, or HAPs. The influence of the variations linked to the global change (loss of biodiversity, alien species introduction, etc) is also investigated.
Different functions are particularly investigated in order to understand their mechanisms (bioaccumulation, detoxification and immune defence) or how they are disturbed (cardiac et sensory function, respiration) in the presence of contaminants (Fig. 1).
