Current Activities
24th and 25th of January 2026 DNA macht Schule at the Grüne Woche in Berlin
Our citizen science project ‘DNA macht Schule’ was presented at the ‘Grüne Woche’ in Berlin. Visitors learned how environmental DNA is used to assess biodiversity in flowing waters. We presented our school program in discussions with children, teenagers, teachers, and experts. In an interactive quiz, visitors discovered exciting stories about different species in our rivers and streams. Many thanks to the BMUKN for the invitation and the opportunity to present our project!
18 December 2025 & 28 January 2026 Dr. Iris is in da house
Iris has successfully defended her PhD thesis titled:
"Navigating complexity: Exploring the untapped potential of mesocosm experiments for multiple-stressor research"
and receicved her PhD Degree
December 2025 Recommendations on DNA metabarcoding standardisation are now available in English
Recommendations from a workshop hosted by VDI and BfN, coordinated by Florian and colleagues, outline how DNA metabarcoding can be standardized for official biodiversity monitoring. Researchers, authorities, and practitioners jointly identified key challenges across sampling, laboratory workflows, and data handling.
The resulting roadmap defines minimum technical requirements, highlights the need for harmonized terminology and robust reference databases, and proposes a structured quality management framework to support routine application in conservation and environmental protection.
10-11 Decemebr 2025 A Productive Visit and Talk by Prof. Feilong Li
It was a true pleasure to welcome our colleague Prof. Feilong Li to our group and discuss our ongoing work on multiple stressors in rivers, (e)DNA based biomonitoring methods, automation in Germany (University of Duisburg-Essen), China (Guangdong University of Technology and Nanjing University), Switzerland (University of Zurich and Eawag). We share many interests and lots of synergies exist to extend for the sake of our planet.
Research Themes
Multiple Stressor Research
Our working group analyzes the effects of single and multiple stress factors on aquatic ecosystems.
Biodiversity Monitoring
We are developing modern genetic tools to assess aquatic biodiversity at much higher resolution.
Genomic Methods Development
One of our focuses is the development of state-of-the-art genomic techniques for the standardized recording of biodiversity.
Population Genetics
We use molecular markers to analyze the genetic diversity and fragmentation of invertebrate populations in rivers.
