Only bio-constructed structures visible from the space, coral reefs constitute one of the vastest ecosystems of our planet. Often symbolized by the image of an oasis in the desert, they shelter a biodiversity never equalled at the marine level, and are supplanted, in number of species (but no kinds), only by the Amazonian forest. Besides their fundamental ecological importance, coral reefs also play a major role for the human populations. Hundred countries, among which a lot of are developing, shelter cliffs in their territorial waters, and more than 500 million people live unless 100 km of this ecosystem. Cliffs are the siege of a fishing of subsistence, but also the source of currencies and jobs  within the framework of the commercial fisheries or of the fish farming. Therefore, coral reefs constitute one of the most precious ecosystems in ecological but also socioeconomic terms. A precious ecosystem, but unfortunately, today threatened by the global changes. Indeed, since the industrial revolution and the generalization of the use of the fossil fuels, the rates of greenhouse gas (mainly the CO2) presents in the atmosphere are increasing constant, with concentrations particularly raised since the 90s. So, the environmental predictions made today (increase of temperature and concomitant reduction in the pH of the oceans in particular) let glimpse difficulties in coming for a development, but especially, sustainable preservation of certain aquacultural sectors. It is the case for perliculture and the culture of the stoups, the two organizations on which will concentrate my research. For example, the increase in the temperatures, could in the long term, to push pearl-bearing oysters and the stoups out of their physiological optima even, out of their tolerances. That would have as a direct consequence a significant deceleration of their production and in the long term the setting in danger of these two aquicultural sectors.
In this context, my objectives of research are:
–           I) to identify the biological functions under environmental pressures
–          II) to characterize the adaptability of these organizations and their populations
–          III) to define possible the interactions between environment and biomineralisation, the driving biological function of these two aquicultures.
In order to answer these questions in their globality of the intégratives and multi-field approaches are developed. They consist in particular, in the study of the triptych genome, epigenomist, phenomist and of his interaction with the environment. With this intention experiments, as well in medium controlled as in natural environment are developed, on various space (from molecules to populations) and temporal (from stage of life to transgenerational) scales.
