At its annual conference, the German Society for Limnology (DGL) awards three prizes to outstanding young researchers. Malwina Schafft from the research group of Robert Arlinghaus received the 3rd prize.

Animal behavioural research is fascinating, not least because it reveals information about how we humans interact with each other as social beings. Behavioural biologists at IGB are deeply involved in exploring the ways in which communities, such as schools of fish, make decisions and the factors that influence individuality. 

Microplastics can be toxic to various aquatic organisms, but how hazardous can they really be? Prof. Justyna Wolinska's research group at IGB has investigated a water flea that is a keystone species to European lakes. It turned out that this species may be under much higher pressure of microplastic hazards than previously thought.

From a scientific perspective, a misleading story is being told about the detection of low concentrations of the toxin-producing brackish water algae Prymnesium parvum in various waters in Brandenburg (Germany): The interpretation spread in the media with reference to the Landesfischereiverband Brandenburg / Berlin e. V. (Brandenburg Fisheries Association) and taken up by institutions, that this result disproves the correlation between algae growth and salt concentration, is scientifically incorrect. 

In water bodies, stones, aquatic plants or the substrate often feel slippery. The cause of this is the so-called biofilm, a wafer-thin layer of countless microbes. They form the basis of aquatic food webs, cleaning and detoxifying the water by breaking down organic pollutants. Using lakes in the French Pyrenees as an example, researchers from the Institut National Polytechnique de Toulouse and the IGB have now shown that the microbial biofilm composition is changing rapidly as a result of climate change and that toxic cyanobacteria are increasing.

The German Federal Agency for Nature Conservation (BfN), in close cooperation with the IGB research group "Light Pollution and Ecophysiology", has published a new special issue of the journal "Natur und Landschaft" on the topic of light pollution.

How can the declining pike stocks in the Bodden be supported? IGB researchers have formulated clear recommendations for politics, authorities and the user groups.

This summer, the water shortage in Europe continues to preoccupy politicians and the public. Small standing water bodies such as natural or artificial ponds, kettle holes or park waters are particularly suffering from the lack of water. In order to raise awareness of this problem and to point out options for action for policymakers, authorities and the civil society, IGB has today published a new IGB Dossier on this important type of water body.
