The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) has once again been awarded the IHK Certificate for Outstanding Training Quality by the Berlin Chamber of Industry and Commerce (IHK).

In an EU consultation, IGB researchers emphasise that the practical implementation of the Nitrates Directive has so far been inadequate.

Aquatic microorganisms in China's Yangtze River are particularly resistant to many antibiotics, posing a high health risk. This is the result of a study by a Chinese research team in which IGB scientist Professor Hans-Peter Grossart was involved.

Die Zahl großer Süßwassertiere wie Störe, Riesenwelse, Flussdelfine, Flusspferde, Krokodile oder große Schildkröten ist weltweit stark zurückgegangen, ebenso wie die Größe ihrer Verbreitungsgebiete. Die Ursachen für die Gefährdung dieser Megafauna sind weitgehend bekannt, die Folgen des Verlusts für die Ökosysteme dagegen kaum.

Fish are changing how they search for and consume prey in warmer waters, with models suggesting extinctions become more likely due to this behaviour change. This is the result of a new study led by researchers from the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena, with the participation of IGB, published in "Nature Climate Change".

The striped marlin is one of the largest and fastest predatory fish in the ocean. This  species forms groups when hunting schools of small fish, aided by its long, spear-like rostrum. A study by the Cluster of Excellence “Science of Intelligence“ (SCIoI) with Humboldt-Universität zu Berlin and IGB now explains how the fish might coordinate the rapid sequence of their attacks without injuring each other. The key to this, they suggest, is rapid colour changes - like a traffic light. Bright body stripes signalise: "Now it's my turn to hunt".

Between 1975 and 2020, the known total cost of invasive aquatic plants to the global economy totalled more than 32 billion US dollars. This was calculated by a team led by IGB and the Institute for Global Food Security at Queen's University Belfast in Ireland. 

A new study with IGB researchers Oleksandra Shumilova and Igor Ogashawara aims to advance the application of declassified satellite data in the fields of ecology and conservation. The team, led by the University of Freiburg, has analysed the spatial and temporal resolution of more than one million images: they cover the entire Earth and all seasons.
