When the weather is nice, it is time to go swimming in a lake, canoeing on a river or having a picnic by the water. The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) shares do's and don'ts for environmentally friendly water fun – including some that are not so obvious.

In a new Leopoldina statement with IGB participation, researchers recommend the restoration of peatlands and floodplains.

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.

The study in Nature Ecology & Evolution shows that shipping shipping has contributed to a significant loss of biodiversity of fish, mussels, snails and small crustaceans in European rivers in recent decades – and that the remaining animal communities are becoming increasingly homogeneous and river-typical species are being lost. Invasive species, on the other hand, are significantly increasing. 

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.

Study in Nature Communications reveals a gene locus responsible for sex determination in the European green toad. This is only the second known genetic mechanism for sex differentiation in amphibians. 

Prolonged rainfall and storm events have caused rivers to burst their banks in parts of Germany. How can we better prepare for such extreme events, and what measures benefit both people and nature? We take a look at the state of the country’s rivers and floodplains and why it is worth rethinking flood protection.

Study in Science shows: High nutrient levels and rising temperatures increase the decomposition rates of organic matter in freshwaters. This can lead to increased CO2 emissions into the atmosphere. Freely accessible maps show the differences for more than 500 stream ecosystems worldwide.
