We test our hypoteses on aquatic ecosystems on our state of the art experimental ecology (mesocosm) systems. Our mesocosm facility includes 24 enclosures. Each enclosure is 2 m wide and 4 m3 in volume. The tanks are equipped with mixing and temperature controllers, and monitored by an online sensor system. The facility includes a field laboratory and a storage space. You can find some pictures from our ongoing experiments.
