Biofilms are complex communities of microorganisms such as bacteria or algae. In aquatic ecosystems, they serve essential functions, e.g. as a food resource. They also play an important role in wastewater treatment and in biofuel production. Read more

Hydroelectric power plants, weirs and waterfalls are often insurmountable barricades for fish. This can have a significant impact on the genetic structure of the separate populations. Whether and to what extent fish ladders mitigate this negative effect is now being investigated for the first time. Read more
