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

October 21, 2015

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.

Today, invasive animals and plants spread all around the globe. Predicting the dynamics of these invasions is of great ecological and socio-economical interest. Yet studying them is fundamentally challenging because of the large spatial and temporal scales involved. Scientists at Eawag and University of Zurich are now using computer simulations and small artificial laboratory worlds, to study how rapid evolution makes invaders spread even faster. Read more

March 3, 2015

Methane emissions are strongly reduced in lakes with anoxic bottom waters. But here – contrary to what has previously been assumed – methane removal is not due to archaea or anaerobic bacteria. A new study on Lake Cadagno in Canton Ticino shows that the microorganisms responsible are aerobic proteobacteria. The oxygen they require is produced in situ by photosynthetic algae. Read more
