To provide the participants with the methodological and conceptual tools necessary to include the habitat selection response within studies of environmental risk.
To integrate each participant in a real study performed by the host institution to verify how contamination might affect species’ spatial distribution and how important contamination is for the habitat selection processes.
1. Development of a new larger scale exposure system (mesocosm) to be used in the experiments by the participants.
2. Performing of the experiments in the multi‐compartmented systems (mesocosms and HeMHAS) for testing the following concepts: avoidance, preference, colonization and habitat selection responses.
3.Discussion about the importance of multi‐compartmentalization of the exposure systems: ecological relevance and conceptual advances linked to the use of this new methodology.
