Underwater Communities (IMAGE) University of Gothenburg Caption With the help of a scraper, Robin Svensson has manipulated underwater communities and recreated the conditions following an ecological disturbance in nature. The species seen here include mussels, sea squirts, algae, sea anemones and barnacles. The experiments were carried out at the Sven Lovén Centre for Marine Sciences field station on the island of Tjärnö.
