Predicting the impact of multiple contaminations at the population level using biomarkers in the three-spined stickleback (Gasterosteus aculeatus)
Predicting the impact of multiple contaminations at the population level using biomarkers in the three-spined stickleback (Gasterosteus aculeatus)
This thesis aims to combine an active in situ biomonitoring approach based on biomarkers with mechanistic DEB-IBM models to predict the impacts of multiple contaminations at the population level.
The work is part of the Interreg ORION project and is based on campaigns to cage three-spined sticklebacks (Gasterosteus aculeatus) along the Meuse axis.
