the Ecotron

is a lab of the Institute of Ecology and Environment (INEE) of the CNRS. It is open to national and international research teams in the fields of ecology, population and community biology and agronomy.

The Ecotron simultaneously enables the climatic conditioning of ecosystems of different sizes and the real time measurement of ecosystems physiological processes. This research infrastructure interfaces between the experiments planned in situ and those carried out in the laboratory. Ecotron’s research themes include fundamental questions about the relationships between biogeochemical cycles and biodiversity within ecosystems under climatic changes conditions. However, the infrastructure is open to other scientific fields (epigenetics, biogeosciences, etc.) which require the analysis of ecosystem’s samples under controlled environmental conditions. The construction of the Ecotron is co-financed by the European Regional Development Fund (ERDF), ANR / AnaEE France, the Occitanie Region. The CNRS very largely invested also in the construction and funds, as well as together with the hosted projects, the yearly running costs. The personnel of the Ecotron is part of the CNRS Institute of Ecology and Environment.

Price list

These prices can be modulated according to the type of contract, in particular in the case of a “collaboration contract”.
