Science that matters

Aquatic ecosystems are fragile. But just how fragile they are has been revealed in a new study by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the University of Zurich. Researchers investigated how climate change is affecting amphipods by shifting the timing of leaf fall in autumn. These creatures feed on leaves and, as the base of the food chain, have an impact on the entire ecosystem.

The Biodiversity Forum of the Swiss Academy of Sciences, together with over 50 experts, has compiled and recently published a report entitled ‘Understanding and shaping biodiversity in Switzerland’. Several Eawag researchers contributed to the report, sharing their expertise in the publication.

The insecticide fipronil has been detected in Swiss waterways in concentrations that are critical for aquatic life. It has not been permitted for use as a plant protection product for many years. A study involving Eawag now shows that the most likely source of contamination is flea and tick repellents for pets.

A new study provides precise data on the origin of plastic in the sea. It could be key to reducing this pollution in a targeted way.
