Department Systems Analysis, Integrated Assessment and Modelling

Integrative Ecological Systems Analysis

Research topics

  • Development of mechanistic and empirical models for aquatic ecosystems by combining knowledge from theoretical ecology (food web theory, metabolic theory of ecology, ecological stoichiometry) and empirical research (trait data bases, field studies). Use of these models for improving our understanding of ecosystem functioning and for the prediction of effects from measures or changing environmental influence factors. Application of Bayesian techniques for model calibration and uncertainty analysis.
  • Model-based decision support for environmental management
    Combining model prediction with multi-criteria decision support techniques to support decisions with multiple objectives and multiple stakeholder perspectives.

Bridging the gap between data science and mechanistic modelling for a better understanding of community composition.
We develop a mechanistic model to simulate aquatic mesocosms for pesticide risk assessment with a focus on uncertainty quantification.
Diatoms use to assess pesticides pollution in the Swiss watercourses
A multi phase research program by Eawag and the Swiss Federal Office for the Environment (FOEN)
We study recent developments in insect abundance, biomass and species richness in terrestrial and aquatic ecosystems of Switzerland.
Interdisciplinary project on biological effects of micropollutants on the periphyton
We investigate human impacts on the community composition of macroinvertebrates and fish in Swiss rivers with statistical analyses of existing monitoring data, food web analyses, and computer models.
Mechanistic modelling of the macroinvertebrate community composition in rivers.
