Theoretical and Experimental Ecology Station
The Aquatic Metatron is an unprecedented platform with the objective of studying the impact of global warming on species of freshwater aquatic environments by reproducing a complex network of interconnected small ponds.
The Aquatic Metatron includes 3 experimental platforms totalling over 250 ponds and 10 artificial rivers to manipulate temperature and dispersal.
Composed of 144 pools of less than 2 m3, the Aquatic Metatron will allow to observe the effects of climate change on species living in freshwater. It is a complex network of interconnected small ponds to study the responses of the entire species community. The pools are interconnected by pipes that allow organisms to move from one to the other.
Everything is controlled by a computer: researchers can change the parameters of each pool, such as temperature, oxygen in the water, etc.
Given the size of the basins, small organisms are placed there, ranging from unicellular to small amphibians and fish. For species that can move, the important thing will be to see if they prefer to move from one basin to another depending on the conditions or if they adapt. But each change could have consequences for several species at once, as they are interdependent.
In addition to the Aquatic Metatron platform, a new hydroecology laboratory is available. The new 1500 m2-buildings allows experiments on marine species in a controlled space.
The Aquatic Metatron is one of the services provided by the research infrastructure AnaEE France for experimental manipulation of managed and unmanaged terrestrial and aquatic ecosystems. www.anaee-france.fr/en/
