Current project:

Resilience of grassland plant communities as influenced by root herbivores under different land use intensities

(DFG Priority Programm 1374: Biodiversity Exploratories, in collaboration with Florian Jeltsch, University Potsdam)

Ecosystem resilience is an essential factor underlying the sustained production of natural resources and ecosystem services in complex systems faced with uncertainty and surprise. Root herbivory can have significant impact on grassland productivity and biodiversity under constant conditions. However, knowledge on root herbivore impact under non-equilibrium conditions such as disturbances, short-term stresses or nutrient pulses is lacking. We combine empirical field work, controlled greenhouse experiments, and ecological modeling to determine the role of root herbivory in plant community resilience after various disturbances and stresses under different land use scenarios.
