As part of the "Special investigation program on the environmental disaster in the Oder River in August 2022" (ODER~SO), we are investigating the effects of increased salt loads and the associated mass development of the brackish water alga Prymnesium parvum on the emergence of aquatic insects. We are interested in changes in the species community (biodiversity) and their possible consequences for the aquatic-terrestrial coupling and deal with the question to what extent floodplain waters can serve as a refuge for aquatic insects during an environmental catastrophe.

Since November 1, we have been supported in the field work, sorting and analysis of the insect community by Nadja Heitmann as a new research assistant in the ODER~SO project.

On January 1, 2023, the new executive committee of the German Society for Limnology (DGL) took up its work. The new executive committee met in Brandenburg an der Havel from 29 to 31.01.23. We are delighted to be a part of it!

By the way: this year's DGL conference will take place in Cologne from September 18 to 22.

In today's issue there is an article with and about us. Among other things, we also show how much we can carry ;)

The 36th annual SIL conference has been taking place in Berlin since August 7th. Together with Ralf Schulz, Alessandro Manfrin, Martin Kainz, Tarn Preet Parmar and Cornelia Twinning we invited to the session "Cross-boundary interactions" and were very pleased about the exciting contributions and interesting discussions.

As part of the AquaTerr project and funded by INTERACT - International Network for Terrestrial Research and Monitoring in the Arctic, research was conducted beyond the Arctic Circle from June 18 to July 5. Stations were the Kilpisjärvi Biological Station in Finland and the nibio Research Station in Svanhovd, Norway.

Thanks to the scientists stationed there for the excellent cooperation!

Together with Dr. Kristin Scharnweber from the University of Potsdam, we deployed emergence traps on several springs in beautiful weather.

On October 1, 2021, Prof. Dominik Martin-Creuzburg took over as head of the research station in Bad Saarow, replacing Prof. Nixdorf as head of the department. In tow are also many laboratory objects, which fortunately survived the long journey from Constance well.

Here's to a good start together!
