Ecosystems

Understand and manage ecosystems

Why does one species of toad live in ponds, while another prefers shingle banks? How does the flora and fauna in a mountain stream change when the glacier has melted away? And how do invasive species affect their new habitat? It is only by answering questions such as these that entire ecosystems can be understood and, to some extent, managed.

Nanomaterials consist of tiny particles of different composition. They are used, for example, in textiles and can enter aquatic systems directly from the factory, while being worn or disposed of. For years, research groups at Eawag have been investigating the effects of artificially manufactured nanoparticles on human beings and the environment. Their preliminary conclusion: nanoparticles have a reputation worse than they deserve. Read more

Biological processes in rivers and brooks emit CO2, partly as a result of decaying plant litter that is deposited in the watercourses from surrounding land. Flowing water thus contributes more to the natural carbon cycle than would a terrestrial ecosystem covering the same area. Up until now, global carbon measures have only taken account of rivers that flow continuously. But about half of the world’s river networks consist of streams that are only periodically flooded. Their CO2 turnover has now been examined for the first time by 94 research institutes from all over the world, among them Eawag and the University of Zurich. Read more
