I am fascinated by the diversity of species and habitats and I am curious about all the factors that matter in changing ecosystem stability. My research focuses on insects and their responses to anthropogenic land use on the community and single species level.

Land-use effects on
plant–herbivore stoichiometry: micro- and macronutrients
As land-use change currently is the major reason for biodiversity loss and species extinction, this project aims to examine the factors that influence the stability and plasticity of ecosystems in the presence of land use such as mowing, grazing or fertilization. Fertilization intensity strongly increases concentrations of macronutrients like N and P in the soil and plants. The goal is to investigate the ability to regulate the oversupply or lack of nutrients and relate it to species' distribution and community composition of herbivorous insects in grasslands. Therefore differently agriculturally managed grasslands in three parts of Germany were intensively sampled. Responses of Auchenorrhyncha, Orthoptera and Heteroptera to land-use intensification are investigated on the community and single-species level. Additional performance experiments will show how herbivores manage different nutrient concentrations in their food or how herbivores from different habitats perform in a common garden experiment.
To link herbivores and their food plants this project is a cooperation with PhD student Verena Busch and PD Dr. Till Kleinebecker (University of Münster). They will focus on soil nutrients, nutrient regulation and homeostasis in plants and conduct elemental analyses.
The project is part of the Biodiversity Exploratories, a long-term and large-scale German research network that focuses on land-use effects on biodiversity and is funded by DFG.
