Research interest

Forest ecology, community ecology and conservation biology with special emphasize on all guilds of fungi, lichens and bryophytes. Special interest on the influence of climate change, forest management and natural disturbance on species-, functional- and phylogenetic diversity

Current projects

  • Artificial dead wood experiment in a montane forest - the role of diversity and amount on decay processes and diversity.
  • Investigation of the influence of natural disturbance by bark beetle infestation on the diversity of montane biocoenosis, with a focus on cryptogams
  • Investigation of the influence of forest management on the diversity of cryptogams in beech forests
  • BIOKLIM Project: Estimation of the influence of climate change on the protected area Bavarian Forest National Park (financed by the Bavarian State Ministry of the Environment and Public Health)
