Principles of biodiversity, species interactions and ecosystem functioning in space and time

A main focus of our research is on testing principles and mechanisms structuring biodiversity, species interactions, and ecosystem functioning. We focus on various levels of biodiversity, from the gene level to ecosystem processes. Furthermore, we integrate different types of species interactions (direct, indirect, antagonistic, mutualistic) and functions (herbivory, pollination, predation), and investigate how they interplay at the community and ecosystem level.  


Evolutionary and ecological consequences of global change

A second main focus is on how global change affects the above mentioned levels of biodiversity and community processes, and what the ecological and evolutionary consequences are. In particular, we are interested in land-use change (intensification of agriculture, urbanization), biological invasions, artificial light at night, and climate change.
