When an endangered species succeeds in repopulating its former habitat, the immediate reaction is one of joy. In the long term, however, its spread is often associated with conflict. One example is the beaver, a keystone species. Other keystone species include the wolf and the bison. These are animals that have an extraordinary impact on the ecosystems in which they live. The reintroduction of such keystone species often restores important processes and ecosystem functions.

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.

Professor Dörthe Tetzlaff was today awarded the highly endowed Water Resources Award of the Rüdiger Kurt Bode Foundation. The prize, which is awarded every three years for outstanding work on the sustainable use of global water resources, honours Tetzlaff's pioneering research on the interactions between climate, land use, water quality and the ecohydrological processes that control water dynamics in landscapes.

A team of authors has been awarded the BWK Publication Prize for their research into the ecological impact of hydropower plants. The paper, published in the journal WASSER UND ABFALL, provides a comprehensive analysis of how hydropower plants affect the hydromorphology and ecological condition of German streams and rivers, thereby counteracting efforts to revitalise them.

To address the growing challenges posed by extreme droughts, researchers are focusing on ecohydrological processes in landscapes. They show that a better understanding of water storage dynamics at medium scales, i.e. areas between 10 and 100 square kilometres, could help to better predict and secure the availability of water resources, even in times of climate change. We spoke to Professor Dörthe Tetzlaff about drought resilience, the hidden water treasures of our landscapes, and more sustainable land and water management.

Die Hydrologin Dörthe Tetzlaff, Leiterin der Abteilung Ökohydrologie und Biogeochemie am Leibniz-Institut für Gewässerökologie und Binnenfischerei (IGB) und Professorin an der Humboldt-Universität zu Berlin (HU Berlin), ist heute mit dem Polubarinova-Kochina Hydrologic Sciences Mid-Career Award ausgezeichnet worden.

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.
