The analysis of DNA fragments and their assignment to individual species – an increasingly well‑established approach – is transforming biodiversity assessment. Samples collected from waterbodies permit rapid biomonitoring of aquatic ecosystems. However, environmental DNA (eDNA) analysis is not without pitfalls. For this reason, guidelines for practitioners have now been developed by a group of experts – including Eawag scientists – coordinated by the Federal Office for the Environment. These guidelines, covering the whole process from sampling to data interpretation, should help to ensure that eDNA applications produce reliable results.

Research Projects

The architecture of community structure, functional traits and trophic networks across blue-green ecosystems
New tools to monitor changes in ecosystem conditions and to quantify genetic changes of populations in (semi-)natural environments to predict how human mediated environmental change will influence stability and resilience of ecosystems.
We test how natural selection acts on quantitative immune defence traits and how ecological factors create variation in the form and strength of selection.
Assess the distribution and genetic structure of all amphipod species in Switzerland.
