We offer doctoral, master, bachelor and examination theses as well as internships in all research areas, in a dynamic and internationally networked working group in a good atmosphere. If you are interested, please contact us or the persons mentioned in the text.
Lack of shade? Too many nutrients from adjacent fields? Modified banks? If a river or stream is not doing well, there are many possible causes, but they are sometimes difficult to detect.
Scientists from UDE have now developed a method that evaluates biological symptoms of rivers and calculates probable causes.
The platform serves to provide online calculation tools for determining the ecological quality of water bodies and is operated by Aquatic Ecology on behalf of the Federal Environment Agency.
Currently available are the methods Phytofluss (Phytoplankton), Phylib (Phytobenthos and Makropyhten), Perlodes (Makrozoobenthos) and fiBS (Fische).
The use of all services of gewaesser-bewertung-berechnung.de is free of charge.
At the moment the platform is only avalibale in German, but other languages are possible and might come in the near future.
The online platform bundles information and results from freshwater ecosystem research. It makes data freely available and is intended to stimulate new research approaches in this field. It offers a unique and comprehensive knowledge base for a sustainable and evidence-based management of our threatened freshwaters and resources. The Aquatic Ecology operates the platform together with three other European institutes.
