October 5, 2017Single-celled bacteria are capable of mixing water layers in lakes – not directly, by movement of their flagella, but by accumulating locally and thus increasing water density. The heavier water then sinks, creating circular currents. Researchers have now observed this process for the first time not just in the laboratory, but in a natural water body – Lake Cadagno (canton of Ticino).

October 3, 2017Trout that live in stable ecosystems divide the prey spectrum among themselves and develop into specialists. In streams with instable food supply, however, the trout become generalists. Sticklebacks from different evolutionary lineages alter their environment by their feeding habits. This is deleterious to their descendants except they are hybrids. Understanding the interaction between species and environment is important for the effective protection of biodiversity.

September 27, 2017In order to protect ship hulls and other surfaces exposed to water from algae, molluscs and crustaceans, they are coated with so-called antifouling biocides. Such biocides do not only protect the surfaces, however, but are often leached into the environment and can harm other life forms.

September 12, 2017Conversion of organic waste into valuable products is becoming more widespread, particularly in low- and middle-income countries. The treatment of waste by larvae of the black soldier fly (BSF) has especially raised much attention in recent years.  Despite these advances, a significant need existed for guidelines on how to set up and operate a commercially viable treatment facility. The Black Soldier Fly Biowaste Processing: A Step-by-Step Guide published in July 2017 summarises the results of ten years of research and development in this field at Eawag and imparts valuable know-how through practical advice and instructions.

September 8, 2017Imported plants, which proliferate widely along bodies of water, for example, are a threat to biodiversity. Based on data from biodiversity monitoring, the WSL, Eawag and the Helmholz Centre for Environmental Research in Halle investigated what influence 31 invasive neophytes have on butterflies in Switzerland.

September 5, 2017Dried-up ponds, culverted streams, contamination with fertilisers and pesticides – the list of adverse effects caused by agriculture to water and waterbodies is a long one. Shortening this list is a major challenge, not only for agriculture but also for society as a whole. Supplying humanity with food is, after all, equally important. At the Eawag Info Day, experts demonstrated that the conflicts between use and protection can be addressed through objective dialogue, transparently stated goals and a broad raft of measures.
