Artificial light is proving to be an ever-growing threat to biodiversity. It's harmful to pollinating insects, bats and a host of other creatures, including zooplankton, a crucial part of the aquatic food chain.
Cholesterolemia fluviatilis: plastic is like the cholesterol in the blood system of our continents, the river systems. It is increasingly accumulating in sediments and floodplains. In Alexander Sukhodolov's research group, Humboldt Fellow Martin Blettler is investigating macroplastic residues on the Tagliamento River in Italy.
When IGB was offered to make a video for Berlin Science Week 2021, we asked the artists Francisca Rocha Goncalves (AQUATAG Project) and Kat Austen (ACTION Project), to get involved.
IGB-Forscher Christian Wolter gibt ein Webinar zum Mortalitätsindex für Fische an Wasserkraftanlagen. Das Projekt wurde vom Bundesamt für Naturschutz (BfN) initiiert und finanziert.
The video shows the River Spree from the source in Saxony to the mouth in River Havel. It gives an introduction to anthropogenic impacts (lignite mining and urban influences) on River Spree and field work methods (water and sediment sampling) frequently used by our Department of Chemical Analytics and Biogeochemistry.
While a response to global climate change might be gradual, abrupt changes are possible when critical thresholds by additional effects of local stressors are exceeded.
Dr. Jan Köhler und Dr. Tom Shatwell konnten mithilfe von Langzeitdaten nachweisen, dass eine Reduzierung von Stickstoff der Schlüssel zur Vermeidung von Algenblüten in Seen sein kann.
IGB scientists Dr. Tom Shatwell and Dr. Jan Köhler have analysed long-term data to prove that decreasing nitrogen in Berlin’s Lake Müggelsee is the key to reducing algal blooms in summer.
