Bad news for Swiss agriculture: several species of insect pests will benefit from a warmer climate. This is one of the findings of geographer Léonard Schneider, a doctoral student at the joint chair of applied climatology at the University of Neuchâtel and the Swiss Federal Research Institute WSL.  His doctorate aims to model the impact of global warming in Switzerland on pests. He publicly defended his thesis on 12 May.

Switzerland is monitoring its biological diversity as part of a global effort to understand its changes and prevent further biodiversity loss. Researchers from ETH Zurich are working on a pioneering pilot study that includes the analysis of genetic diversity of native species.

Scientists at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL have discovered microbes that degrade plastic at cool temperatures. This opens up new perspectives for recycling certain types of plastic. Most known microbes require at least 30°C for their decomposition work.

Eawag researcher Johannes Raths has won a prize for his study of increased pollutant absorption with rising water temperatures.

When glaciers retreat, the habitats for cold-water organisms also change. Researchers have now modelled where refuges that are vital for biodiversity in glacial rivers will remain in the future.

There are fewer and fewer insect species, individuals and biomass worldwide. Moreover, their composition is becoming more uniform. This is highlighted in a special issue of the journal Biology Letters. It outlines the causes and consequences of the global crash of insect populations and possible measures to counter it.
