Biodiversity

Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade and that three mechanisms are primarily responsible for this. These findings are of great importance for the management of ecosystems.

Ecological communities in rivers and lakes are responding to climate change in a similar way to communities on land. This is shown by the first comprehensive comparison of freshwater and terrestrial ecosystems around the globe, co-led by Eawag and WSL. When temperatures rise, warm-loving species are the main beneficiaries. One surprising exception may be the plankton.

From the giant blue whale to minuscule microbes, all creatures on this earth continuously shed traces of their DNA. These clues help researchers to determine the degree of biological diversity.

New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity.

Forests renew themselves naturally. There has been very little research into how exactly this happens – until now. Researchers at ETH Zurich and WSL have set themselves the task of solving this puzzle.
