Description

In MULTICOP, we study the complex question of how multiple stressors (biological stress and anthropogenic toxicants) affect critical biological responses at the individual- and population-level in important coastal marine animals: copepods. The primary objective in MULTICOP is to identify the dominant mechanism of interactions between biotic stressors and contaminant toxicity, exemplified in our project by combining predation risk and copper exposure to copepods.

We take an integrative approach, combining lab, field and dynamic energy budget (DEB) modelling studies, to understand how perceived predation risk affects the toxicity response to copper exposure – an antifouling biocide used in high volume in shipping and aquaculture along the Norwegian coast. Our results will provide much needed knowledge of the biological effects from multiple stressors with importance to future environmental management and seafood production.

My role

Using DEB-based models to identify the energetic processes targeted by predation risk and copper (and the interaction of these two stresses). To this end, the data generated by the other work packages in the project will be integrated, adding existing published and non-published data. Starting point for this work package is the model developed for another copepod species, namely Calanus finmarchicus (Jager et al., 2017). Foraging data from WP1 will provide much-needed information on knowledge gaps identified in on specific feeding rates throughout ontogeny. The DEB-based model will also be used to relate observed differences between individuals to the underlying variations in their energy budgets (Jager et al., 2013). DEB models function as the toxicodynamic part of toxicokinetic-toxicodynamic (TKTD) models, and this work package will use DEB in combination with population modelling to predict consequences of combined stress on copepod population dynamics.
