Key research topics and activities

Human impact on freshwater ecosystems


Animal dispersal and recruitment in stream networks

  • Landscape connectivity for aquatic and terrestrial life stages of aquatic organisms
  • Population genetics (fish, macroinvertebrates) of stream populations
  • Emergence of life history bottlenecks for freshwater species with complex life cycles (aquatic insects, migratory fish)


Functional ecology

  • Cross-ecosystem links (subsidy ecology)
  • Stable isotope use in evaluating human impact on freshwater food webs


Restoration ecology: combining social and ecological goals        

  • Socio-ecological effects of river connectivity restoration
  • Knowledge transfer from research to practitioners


Student supervision (Master students)
