How will insecticides affect streams under climate change?
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.

Ecotox Facilities III: Landau Stream Mesocosm Facility
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.
42 days set-up, 42 days mesocosm study
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.
Ecotox Facilities II: Laboratory floodplain mesocosm system
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.
