The structures and ecosystems of rivers are often irreversibly modified.  Some rivers are more or less permanently impassable for fish and other animals. Reservoirs can become a source for greenhouse gases. Researchers from IGB investigate the human impact on freshwater ecosystems and biodiversity. (Complete press release in German only.)
