Variations of Fucus vesiculosus photophysiological performance in the Kiel Outdoor Benthocosms in four different seasons – relative electron transport rate and maximum quantum yield
Ocean warming and acidification may substantially affect the photophysiological performance of keystone species such as Fucus vesiculosus (Phaeophyceae) in shallow coastal waters. In four consecutive benthic mesocosm experiments (Kiel Outdoor Benthocosm, Kiel, Germany, 54°20'N; 10°09'E), w...

Ocean warming and acidification may substantially affect the photophysiological performance of keystone species such as Fucus vesiculosus (Phaeophyceae) in shallow coastal waters.
