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.
