Adaptive physiological and behavioural responses of organisms to multiple environmental stresses

,

observation, experimentation and modelling

One of the great strengths of the PANORAMA team lies in the study of the physiological and behavioural responses of marine organisms to environmental constraints, whether of biotic or abiotic origin. The team strives to understand the effects of factors related to climate change (warming, acidification, hypoxia, nutritional constraints) and/or emerging pollutants on different species present mainly in coastal areas, in a monofactorial or multistress manner. In particular, it is developing approaches in ecotoxicology aimed at studying, on different models, the impact of micro- and nanoplastics, for which our laboratory is a precursor, or that of toxic microalgae, which also represents one of the laboratory’s strengths, or even that of diffuse pollution. We have exceptional structures and experimental and observation means that allow us to monitor the effect of these disturbances and contaminants, in large volumes and over the entire life cycle of the organisms: gametes, embryos, larvae, juveniles and adults. Thanks to this, we also understand the inter- and trans-generational effects of contaminants, pollutants, toxic microalgae and their toxins. Our experimental approaches are complemented by parallel studies in the natural environment where observational monitoring (e.g. monitoring of toxic microalgae blooms) and in situ experiments (e.g. caging experiments) are carried out. Our laboratory is very present in Brest, in the framework of sustained collaborations with CEDRE and ANSES, but also at the national level, with active participation in the GdR Aquatic Ecotoxicology, and the animation of the GdR PHYCOTOX and the GdR “Polymers and Oceans”. Our approach integrates all levels of biological organisation thanks to the new “omics” approaches in ecotoxicology, in association with cell biology, histology and eco-physiology measurements. We complete this coupling of observation and experimentation with modelling in conjunction with the “Coupling” Transverse Axis and the modellers of the DISCOVERY team.
