Tiny plastic particles can be found everywhere.

Uni News 10 April 2024

Microplastics can be found in the world's most remote marine areas. In the Antarctic, the pollution is even higher than previously assumed. Clara Leistenschneider, PhD, investigates this in her publication. more

Microplastics in the Water Column of the Rhine River Near Basel: 22 Months of Sampling - Manuskript von Gabriel Erni-Cassola*, Reto Dolf, and Patricia Burkhardt-Holm*

MGU team takes microplastic samples over 22 months at the Rhine Monitoring Station (RÜS)

The measured microplastic concentrations in river surface waters fluctuate greatly. These fluctuations depend on various factors. By representatively sampling the entire Rhine River cross-section near Basel through five sampling points over 22 months, our research group found an average microplastic concentration (50-3000 μm) of 4.48 n m-3 and estimates a wide-ranging load of between 4.04 × 102 n s-1 and 3.57 × 105 n s-1.

Grundel invasive

10-year research at MGU on invasive gobies.

Poster von Attila Rüegg

The gobies were able to spread strongly on Europe's increasingly frequented waterways. The construction of the Main-Danube
Canal enabled the gobies to enter the Rhine. The navigability of the river and the increasing construction of riverbanks with
stone fills led to a loss of the original habitats. These newly created habitats, which were far removed from nature
were quickly and efficiently colonized by the invaders.

For more than 10 years, the MGU team has conducted monitoring with fish traps at the same location in the Rhine harbor of Basel. According to Prof. Holm, it is impossible to predict how much the goby population will increase this time.

"Schwarzmeergrundeln Schweiz": Strategie, Massnahmen und Umsetzung - eine Bilanz

Article by Dr. Karen Bussmann and Prof. Patricia Holm

Invasive species are among the greatest threats to biodiversity worldwide. The Black Sea gobies, originating from the Black Sea, are now also spreading in Switzerland and pose a great threat to sensitive fish such as nase, grayling or trout. In order to protect native species, the strategy "Black Sea Gobies Switzerland" was developed.

"Du bist so eine miese Ratte!"

Our team studied - among other things - the personality of round gobies. Bolder fish overcome obstacles more easily and migrate upstream. Native species are displaced. more

"Schwarzmeergrundel nähert sich dem Bodensee"

Joschka Wiegleb describes the function of his developed goby barrier. The aim is to prevent the round goby from spreading upstream toward Lake Constance. The invasive fish was first sighted more than ten years ago in the port of Kleinhüningen in Basel.

Workshop on Stickleback and Round Goby in the Baltic Sea

Landings of round goby increased significantly in Latvia during the last years, while stickleback landings decreased over the last five decades but most recently show a slight increase. A targeted round goby fishery exists in Latvian waters, while the stickleback is solely taken as bycatch in all Baltic countries. Both fisheries are currently unmanaged and, with the exception of round goby fishery in Latvia, unregulated.

The Arctic under pressure

Man-made change in the Arctic and the role of Switzerland

The Arctic is suffering particularly badly from climate change and pollution. While the Arctic "thaw" threatens the livelihoods of indigenous peoples, industrialized countries see it as an opportunity for new economic activity. But the changes in the Arctic are also having a global impact. Therefore, preservation of the Arctic eco- and climate systems is essential for sustainable development outside the Arctic - also in Switzerland.

Invasive Round Goby Larvae as stowaways in small watercraft motors

Dr. Karen Bussmann presented our methods and approaches with invasive species at the conference and was able to compare them with those from research and practice of colleagues from overseas.
The creative approaches in the area of "outrech" and "public engagement" were particularly interesting.

Together with other researchers, Clara Leistenschneider examined a colony of emperor penguins in the remote Atka Bay on the northeastern edge of the Ekstrom Ice Shelf. "There have already been studies of water samples there in which we found microplastics, albeit only in low concentrations," the doctoral student explains. However, the impact of the pollution on the animals living there was still largely unexplored.
