With our work we want to understand how species occur in space and time, how they interact, and how processes such as species invasions, dispersal or climate change affect natural communities.
Metapopulation, metacommunity and meta-ecosystems theory provide a conceptual framework for our research. We use both an experimental and a comparative approach, and integrate them with theoretical models. Depending on the question, we use a variety of study systems, ranging from protists (microcosm-experiments), to aquatic invertebrates (field studies with amphipods, planktonic crustaceans, and freshwater insects), and Lepidoptera. Currently, we are especially interested how dispersal in dendritic networks affects community diversity and ecosystem processes.
