Research interests

In my research, I explore drivers of forest ecosystem dynamics as well as consequences of biodiversity change on forest ecosystem functioning. Trees as very long-lived organisms face a multitude of challenges across their life-time, including climate change, herbivory, nitrogen deposition, or impacts from forest management. I am interested in how these drivers affect single tree species as well as forest biodiversity and structure, and how such changes alter forest ecosystem functioning.

My work encompasses different scales, from single leaf traits to continental patterns of forest multifunctionality, and from trees’ responses to herbivory within a few hours to relationships between tree growth and climate across centuries. In my research, I use observational data, field experiments, as well as data synthesis.

Main areas of research

  • functional biodiversity
  • tree-herbivore interactions
  • global change ecology
  • disturbance ecology and ecological succession
  • dendroecology

Projects

Current project: TempTurn – Temporal turnover of functional biodiversity in forests after disturbances (with a focus on tree functional diversity in temperate forest ecosystems)

In my past projects, I have explored

  • Climate change effects on growth responses of arctic treeline trees as main driver of boreal forest dynamics (using dendro-ecological methods)
  • Tree-mammal interactions in forests – in particular, responses of tree saplings to deer browsing and the role of sapling diversity for deer foraging choices, using forest inventory data as well as a multi-tree-species and multi-trait experiment
  • Biodiversity effects on forest multifunctionality and how this relationship is driven by environmental context
  • Effects of global change and forest management on population characteristics and individual traits of forest herbs
  • Global woody demography – the potential of demographic data and approaches to inform tree species conservation and forest management
