Overview

Can populations adapt to a changing environment via evolutionary adaptation? Which roles do epigenetic versus genomic changes play for such adaptation? What is the interaction between ecological compositional changes as response to warming or ocean acidification versus the evolutionary change within populations? Can clonal organisms evolve?

These are the questions our group is addressing in organisms that range from phytoplankton, seagrasses, zooplankton species to (commercially important) fish species. Strong ecological interactions such as harvesting, host-parasite interactions and invasive species in their new habitat are prime examples where evolution-in-action can be observed in real time in the marine realm.
 

Our research is integrated into the initiatives Kiel Evolution Centre, the Kiel Plant Center and the Research Training Group Translational Evolutionary Research. We are also full members of the Kiel Life Science (KLS) at Kiel University.
