Climshift Project: Regime Shifts in Freshwater Ecosystems

Our project is about the effect of
multiple stressors on shallow aquatic ecosystems and in particular we’re looking at agricultural runoff and climate change and the combined stress by those two. The agricultural runoff is
compost by nutrients mainly. We also have heavy metals and different pesticides.
We are using two different temperatures. So we are having a closer look at the effect of elevated temperatures.
We have two climate chambers. One is set at 22 °C and one at 26°C. We can see first results and first effects: So in particular we are looking at the
tipping point between the mycrophyte dominated state with the
clear water and the algae dominated state with the turbid water. And we can see, that with the increasing agricultural runoff we get more algae. This is also promoted by the elevated temperature.
