A study in Nature Communications has shown at the genetic level how bacteriophages can maintain an important metabolic pathway in infected aquatic bacteria – presumably in order to have enough energy for their own reproduction. 

Light pollution is more serious than we realise: Moths not only lose their orientation directly under street lights. Their flight behaviour outside the illuminated area is also disturbed, so that street lighting can even act as a barrier. This is shown by a study with the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), which was published in the scientific journal PNAS.

Researchers from all over Europe, with the participation of IGB, have created high-standard reference genomes for 98 species as part of the European Reference Genome Atlas (ERGA) pilot project. This collaboration of scientists from 33 countries is an important milestone on the way to a reference genome database for European animals, plants and fungi. The results were presented in an article in the scientific journal npj Biodiversity.

It is a milestone in European species conservation: Today, one hundred young European sturgeon (Acipenser sturio) were released into the Elbe River near Magdeburg as part of a long-term reintroduction programme and in the presence of the German Environment Minister Steffi Lemke. It is the first sturgeon offspring for the river since 2015. This action is an important step towards re-establishing a self-sustaining sturgeon population in one of Germany's largest river systems.

Postdoctoral researcher Nedim Tüzün's new research project ECO-EVO ALAN is funded by a Marie Skłodowska-Curie Actions Fellowship. It focuses on how artificial light at night (ALAN) affects aquatic ecosystems, especially urban ponds. While the negative effects of ALAN on terrestrial ecosystems are well documented, there are still many unanswered questions about its effects on aquatic systems. 

Researchers from IGB sequenced the complete genome of the microalgae of the Oder disaster.They also identified the gene sequences that are responsible for toxin formation. This is an important step on the way to an early warning system. The study was published in the journal Current Biology.

Researchers under the lead of Hans-Peter Grossart have now identified fungi that can efficiently degrade plastic polymers made of polyurethane, polyethylene and tyre rubber. Contrary to previous assumptions, no pre-treatment of the plastics was necessary. The study has been published in Science of the Total Environment.

Tailored and shielded street lamps make the light source almost invisible outside the illuminated area and significantly reduces the lethal attraction for flying insects in different environments. The researchers see this as an important technical solution to reduce insect mortality. The study was published in Communications Biology.
