Too little rain, too little water in the landscape – so simple, so serious. Even if the drought is obvious because freshwaters carry less water, plants wither and the soil becomes brittle and cracked, the drying out itself is a complex process in which the spatial context plays an important role. Professor Dörthe Tetzlaff from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) is investigating this interplay of environmental factors, water storage and water flows in the landscape, focussing on the Berlin-Brandenburg region.

In an ICPO consultation, the IGB recommends that the salinity of the Oder should be made an important management issue. 

Tires abrade fine particles when driving. These contain a complex mixture of different compounds, including toxic substances. If the tire wear particles end up in freshwater ecosystems, the pollutants are leached out there. A new review article in the Journal of Environmental Management summarises the current state of knowledge on the occurrence of tire wear particles and the release of pollutants in aquatic ecosystems. The researchers warn of the toxic effects on aquatic organisms and associated ecological consequences.

Biological invasions are widely acknowledged as a serious threat to biodiversity, global economies, and a good quality of life. Yet, they are not universally perceived as a nuisance and are sometimes gaining – often unexpectedly – cultural acceptance in local communities around the world. The consequences of this acceptance are not trivial for the management of invasive species.
