My research interests are very broad but have focused mainly on habitat shifts among algae and zooplankton from sediment to water, as well as on fish mass-migrations between lakes and surrounding wetlands. Recently, I have studied how zooplankton utilize their morphological and behavioral (migratory) plasticity to handle simultaneous multiple threats, such as ultraviolet radiation (UV) and predation; i.e. the trade-off between being eaten by predators and dying from UV induced cell damages.

Within the framework of the Linné grant our research group aims at developing techniques, e.g. nano-scaled tracers, to follow individual zooplankton (mm sized animals) in order to answer questions like. “Why are they migrating?”, “What induces the migratory behavior?”, and “Which are the consequences of the migrations?” Moreover, we aim at answering these questions also with respect to the large scale cyprinid fish migrations by using individually marked fish. The general aim of our research is to understand how migratory behavior and patterns affect the structure and function of aquatic ecosystems.
