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

Cichlids – unlike the Nile perch – have a second set of jaws, but this trait is not always advantageous. (Photo: Eawag)
November 26, 2015

When the biodiversity of an ecosystem is reduced by invasive species, competition for food plays a more important role than has previously been supposed. This was the conclusion of research conducted by Eawag and Bern University scientists on cichlid species in Lake Victoria, which suffered mass extinction following the introduction of the fish-eating Nile perch in the 1950s.

According to a new international study – in which Eawag scientists played a leading role – the global climate shifted to a warmer state in the late 1980s. The research also indicates that the cooling initially caused by the eruption of El Chichón was followed by a rapid rebound in global temperatures. Read more

What is required to facilitate the adoption of new technologies such as potable water reuse? According to a study carried out by environmental social scientists in California, users need to see not only how an innovation benefits them personally, but also that it is compatible the community’s values and can become a routine part of daily life.
