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.
