Background

 

I am an experimental ecologist with a strong interest in conceptual issues of invasion biology and ecosystem functioning. During my Diploma thesis I studied the relationship between diversity and productivity in grassland ecosystems and the effect of gastropod herbivory on plant communities of native and exotic origin. I joined iDiv because it is a great opportunity for me to contribute to an interdisciplinary and international research committed to understand the way biodiversity affects all aspects of our lives.

Research Project

 

My current research project at the iDiv focus at mechanisms maintaining plant species diversity in grassland ecosystems in Central Germany, especially how food-web interactions between plants and their natural enemies, like pathogens and herbivores influences ecological functions. These interactions are assumed to be of particular importance for ecosystem responses to global environmental changes, as biological invasions and climate-driven shifts in species ranges will lead to novel communities and to mismatches between interacting species.

However, the importance of antagonistic interactions plant species coexistence has not been tested experimentally so far.

The central questions of the project are

  1. How is biodiversity generated and maintained in the face of global change?
  2. How does the complexity of food-web interactions influence ecological functions?
  3. Can we predict the functions of novel species communities?

Methods to be used

We will establish a field experiment in existing, species rich grassland vegetation to which we will add native and exotic plant species sown at different frequencies. To test the importance of antagonistic interactions for the maintenance of plant diversity we will exclude insects and pathogens by applying insecticides and fungicides. Complementary microcosm studies in the greenhouse to study trade-offs between a plan species competitive ability and defense mechanisms and molecular analyses to identify fungal species will contribute to provide basic information for future research how global changes impact the functioning of ecological communities.
