Ecosystem

All living organisms that respire have to get rid of electrons. In oxygen-free environments, microorganisms deploy special molecules which act as extracellular electron shuttles to transfer the electrons from cells to minerals. A group of researchers has now discovered what determines the electron transfer efficiency of these “taxi” cars: the energy differences of the transported electrons.

Most trees live in symbiosis with fungi. ETH Zurich researchers show just how important this partnership is for tree growth through the first-ever comprehensive data analysis compiled for European forests on a massive scale.

Scientists from EPFL and the Mediterranean Institute of Oceanography (MIO) have discovered a new source of organic phosphorus that is fertilizing remote marine ecosystems via atmospheric particles. This finding could help researchers better understand how marine ecosystems respond to climate change.

In the "Projet Lac" research project, 35 lakes in the Alpine region were systematically examined for their fish populations for the first time: In Switzerland alone, 106 fish species were detected. With almost 20% of all known fish species in Europe, Switzerland is one of the hotspots for fish species diversity. The results are now the basis for measures for sustainable fishing and the protection of this still preserved diversity.

It makes sense to study land and water habitats together, according to the initial findings of the Blue-Green Biodiversity initiative.

With around 200 pictures and texts, the new Water Timeline takes you through 200 years of the eventful history of Swiss water protection. It aims to show how shifts towards more sustainable management of natural resources can be shaped.
