The Department of Marine Botany at the University of Bremen studies ecological and physiological responses of marine algae towards environmental change. Our particular focus is on seaweeds from temperate to polar regions.

We are addressing physiological acclimation patterns under altered radiation, temperature and nutrient conditions. As the species-dependent tolerance towards environmental (stress-) factors also determines competitive success of a species in a given habitat, we are also studying changes on the community to ecosystem level. Conclusively, our studies can contribute to predict the future development of coastal ecosystems under global and regional environmental change.

In cooperation with the Alfred Wegener Institute for Polar and Marine Research (AWI) our department coordinates the long-term research program on the Biology of Arctic benthic algae at the French/German Arctic AWIPEV research station. Furthermore, we are coordinating the European H2020 project FACE-IT.

The Department of Marine Botany contributes to teaching in the Bachelor program of Biology, as well as the Master program Marine Biology, including International Studies in Aquatic Tropical Ecology (ISATEC).

We started our feasibility study on kelp plantation in the German Bight as potential contribution to carbon sequestration and habitat provision. The project will be conducted within the research consortium sea4soCiety within the CDRmare research mission of the "Deutsche Allianz Meeresforschung"
