Such processes have been proven to affect the chemistry of carbonate in seawater, threatening many marine organisms that critically rely on calcium carbonate secretion for the production of calcified hard parts. Statoliths are non-skeletal carbonates included in the gravireceptors of most invertebrates, responsible for the gravitational orientation involved in many behavioral responses. In bivalves and marine gastropods, these structures are formed early in life and play a key role in major larval behaviors such as feeding, swimming, etc. In this sense, the malformation of statoliths can impact dispersal, migration and even survival, with potential consequences for the establishment, replacement and, ultimately, perpetuation of populations. In addition to the high ecological relevance, many species in these groups are also food resources, some of them dominant in the global panorama of shellfish fisheries and aquaculture known to be threatened by the AAO. Production failures under increased acidity have been reported attributable to abnormal calcification of shells, but the potential sensory dysfunction due to statolith malformation, which is very likely, has never been addressed. The CliMaStat project arises to fill this gap in knowledge and to show if and in what way STATOLITH MALFORMATION AFFECTS THE SENSORY FUNCTION OF BIVALVES AND GASTROPODS UNDER THE EXPECTED SCENARIOS OF AAO, knowing that an abnormal calcification of statoliths can induce behavioral changes that affect life cycles, natural populations, fisheries and aquaculture production.
With a multidisciplinary research team, the CliMaStat project will integrate methodologies from domains as distinct as they are complementary: biology, ecology, physiology, geochemistry and physics. This perspective will allow the development and application of an integrated approach, which brings together the multiple skills of the team to achieve the proposed objectives and produce scientific knowledge of global relevance in the context of climate change in the oceans and its impacts on ecosystems and their services."
