Ecological Modelling

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.

Mechanistic modelling of the macroinvertebrate community composition in rivers.
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.
Decision support for river management by combining the prediction of effects of suggested measures with quantified societal goals.
Restoring rivers for for effective catchment management.
One of the most important challenges in environmental toxicology is to understand how responses to chemical pollutants scale through levels of biological complexity...
Development of unified ecological assessment procedures for river management.
