An Ecotron is an experimental and instrumented device which makes it possible to:
- Control the environment of natural, simplified or completely artificial ecosystems,
- Measure processes generated by organisms in these ecosystems, including material and energy flows.
Its principle is to confine terrestrial or aquatic, continental or marine ecosystems in totally or partially sealed chambers capable of generating a wide range of physical and chemical conditions and to study their flows. The two French Ecotrons offer study scales from micro to macrocosm.
