Research interests

  • Population dynamics
  • Predator-prey interactionsEcosystem functioning considering spatiotemporal scales
  • Effects of small-scale habitat utilization patterns on large scale population fitness
  • Habitat connectivity
  • Fish nurseries


  • Comparison of ecology and population biological parameters of smelts from the Weser, Elbe and the coastal sea of the German Bight.
