The project Hydro-ecological Conditions for the Emergence of Botulism and Occurrence of Toxins in Ponds (CHABOTÉ) aims to identify the environmental conditions and hydro-ecological mechanisms that favour the emergence of episodes of avian botulism, a disease responsible for significant mortality in many French ponds.
Led by Damien Banas (University of Lorraine, L2A) and Ariane Payne (French Office for Biodiversity), this project is being conducted in collaboration with ANSES (Céline Richomme and Caroline Le Maréchal) and the Marais d'Orx and Lac du Der nature reserves. The project is based on in situ monitoring and analysis of flows between biotic and abiotic compartments in lentic ecosystems, including the Der and Marais d'Orx ponds, which are currently affected, while the ponds in Lorraine still appear to be relatively unspoilt. In the context of global warming, CHABOTÉ aims to assess the future vulnerability of these systems and to produce knowledge that can be used for the prevention and management of health risks.
