The objectives of this project, whose acoustic telemetry phase will take place on EUROPA Island, are to acquire data and contribute to the development of new tools and methodologies to better estimate the interactions of turtle populations with human activities and to study the influence of available environmental variables on the dispersion and behavior of juvenile individuals. Ultimately, this project could enable the scientific community and managers of French National Action Plans for sea turtles to propose innovative and relevant approaches to population monitoring based on this new knowledge and an automatic and sustainable data collection system for juvenile sea turtles, adapted to isolated environments and capable of being extended to other fragile species of high heritage value.
