Project title: Linking individual and community level effects

Use energy-budget, population and food-web models to extrapolate chemical-induced changes in feeding rate to population and community-level responses that underpin key ecosystem functions and service.
Identify effect thresholds for each level of biological organization.
Apply modelling framework to case study chemicals.

Expected results:

Empirical evidence of individual-based threshold effect levels for study chemicals.
Application of energy-budget and population models to translate individual-level effects to changes in populations.
Relationships between individual-level effects and community processes and response to chemical exposure.
Understanding of how chemical-induced effects on the feeding rate translates into changes in population growth and community-level processes and the ecosystem functions and services they drive.
Elucidation of the association between individual-level physiological responses and changes in molecular markers (with ESR7).
Inter-specific comparison of the translation function linking individual-level effects and population-level responses (with ESR10).

Place: Sheffield, United Kingdom
Planned secondments:
RIVM, M19, 1 month, learn about trait-based approaches
AU, M25, 2 months, to collaborate with ESR10
EI, M30, 1 month, field methods and exposure assessment
Work packages: 4 - Predicting effects on ecosystem services through AOPs
3 - Linking molecular responses to effects at higher biological levels using adverse outcome pathways (AOPs)
