Research Interests

  1. Disturbance ecology in running water ecosystems (since 1992)
  2. Experimental design and statistical data analysis (since 1993)
  3. Effects of human land use activities on running water ecosystems, especially impacts agriculture and multiple stressors (since 2002), also water abstraction and other flow regime changes (environmental flow ecology; since 1990)
  4. River restoration (since 2000)
  5. Estuary ecology (since 2005; PhD Antje Bierschenk)
  6. Pond ecology and life history strategies of aquatic insects (since 2012; PhD Tanya Dann)
  7. Ecology of shallow lakeshores (since 2008)
