Individual bacterial cells have short memories. But groups of bacteria can develop a collective memory that can increase their tolerance to stress. This has been demonstrated experimentally for the first time in a study by Eawag and ETH Zurich scientists published in PNAS. Read more

Nathalie Dubois from the Surface Waters Research and Management Department has received a Swiss National Science Foundation (SNSF) professorship. She plans to use the professorship to research what effects early human activity had on ecosystems in previously uninhabited eastern Pacific islands. Read more

Sometimes evolution proceeds much more rapidly than we might think. Genetic analysis makes it possible to detect the earliest stages of species formation and to gain a better understanding of speciation processes. Read more

In Switzerland, conflicts between the societal goals of agricultural production and protection of waterbodies arise in particular with regard to rehabilitation measures, nutrient management and ecological compensation areas. Read more

In mountainous terrain, peaks and valleys (grey background) are isolated habitats, like islands in the ocean, whereas mid-elevation sites (yellow-red gradient) form well-connected patches. (Picture: E. Bertuzzo)

A warming climate is likely to drive species to higher, cooler altitudes. A new study highlights a less obvious, yet crucial way in which their new habitat could differ from the one they leave behind. Read more

Hydroelectric power plants, weirs and waterfalls are often insurmountable barricades for fish. This can have a significant impact on the genetic structure of the separate populations. Whether and to what extent fish ladders mitigate this negative effect is now being investigated for the first time. Read more
