How climate change will alter the effects of toxicants is a key concern in the 21st Century. Rising water temperature can increase the toxicity of some contaminants to stream-dwelling animals in laboratory conditions, as has been shown for the most widely used insecticides in the world – the neonicotinoids. But until this study, whether this translates to more realistic environmental scenarios remained to be tested. In this blogpost, Sam Macaulay talks about his mesocosm experiment studying the effects of rising water temperatures and neonicotinoids on stream invertebrate communities.Continue reading

In this post, Verena Sesin talks about their recent publication “Macrophytes are highly sensitive to the herbicide diquat dibromide in test systems of varying complexity”.
In this series of posts, we present you some of the equipment and facilities we use to assess the fate and environmental impacts of chemical stressors. This time: The Landau Stream Mesocosm Facility.
Large-scale experiments give us a more realistic idea of pesticide toxicity than single-species tests. Mesocosm studies for example simulate natural ecosystems and can include several trophic levels, which help us to detect both direct and indirect pesticide effects. However, large scale means large workload. In the scope of my master thesis I set up and performed a mesocosm experiment at the National Wildlife Research Center in Ottawa, Canada. Follow me through my 10 steps of set-up.
In this new series of posts we present you some of the equipment and facilities we use to assess the fate and environmental impacts of chemical stressors. This time Sandra Kurtz, Dr.-Ing. George, and Prof. Dr. Schaumann present the Laboratory floodplain mesocosm system.
In this post, Anna Kästel and Stefanie Allgeier talk about our recently finished outdoor mesocosm study dealing with the potential effects of Bacillus thurinigiensis israelensis (Bti) application on an exemplary wetland ecosystem. Continue reading
