Deficits in the ecological state of small Swiss streams

A survey of 99 small Swiss streams reveals that the majority of the studied streams have significant deficits in their ecological condition and can only fulfil their function as a habitat for animals to a limited extent. Insect larvae and other small animals that react sensitively to pesticides are missing in over 70 per cent of the streams examined. Statistical analyses indicate that these aquatic organisms are particularly impacted when the structure and morphology of the stream bed has been altered or if the proportion of agricultural land in the catchment area is high.

The risky life of a lake trout

Lake trout migrate between different habitats many times over their lives. This helps them grow larger and have more offspring than sedentary trout. However, it also exposes them to dangers – both natural risks and from human intervention in their habitats. Read more

Impacts of invasive species transcend ecosystem boundaries

Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade. Read more

Keeping an eye on pollutants in stormwater
When rainwater is used as a resource, persistent, mobile and toxic (PMT) substances need to be better monitored. The Royal Society of Chemistry has recognised a study led by Eawag as the outstanding review of 2023. Short version in the video.

Cover picture: Technicians Andreas Taverna and Danina Schmidt from the Eawag Fish Ecology and Evolution research department in Kastanienbaum take water samples in Lake Lucerne from the Eawag research vessel "Perca". To do this, they slowly lower a Schroeder flask to 20 metres and quickly raise it again. A defined amount of water collects in the bottle per metre of water depth. These composite samples can be used to collect important data on algae composition, for example, and thus analyse the productivity of the lake. (Photo: Alessandro della Bella)
