Located in the French Pyrenees, the Metatron comprises 48 units, each stretches 100-m² * 2-m height, where we can manipulate climatic conditions (temperature, humidity or solar radiation). Units are connected by corridors allowing migration from one environment to another. The Metatron focuses on climatic effects on population dynamics, especially in the framework of the global warming and fragmentation.

An experimental research infrastructure dedicated to the study of ecosystems, organisms and biodiversity in the context of environmental changes. The Ecotron is a laboratory of the Institute of Ecology and Environment (CNRS) open to national and international scientists’ consortia in the fields of ecology, population and community biology and agronomy. The Ecotron allows a precise conditioning of the environment and on line measurements of states and activities (fluxes) of organisms and ecosystems at various scales. This facility bridges the gap between the complexity of in natura studies and the simplicity of laboratory experiments. The research topics to be addressed in the Ecotron include fundamental questions about biogeochemical cycles and the role of biodiversity in ecosystem processes, but tests of ecological theories as well as the applied aspects of optimizing ecosystem services are also desirable projects. http://www.ecotron.cnrs.fr/index.php/en/

AnaEE France has brought together in an integrated network a unique collection of experimental platforms in controlled, semi-natural or natural environments, analysis platforms and shared instruments as well as modeling platforms and Database Information Systems, all devoted to the biology of continental ecosystems. The infrastructure is built around three main service offerings that provide access to a range of experimental facilities: the Très Grande Infrastructure de Recherche des Écotrons - Écotrons Very Large Research Infrastructure, four experimental platforms in semi-natural environments, and some 20 natural sites in metropolitan France and French Guiana where long-term experiments are conducted in forests, pastures, lakes and crops. In the field of environmental microbiology, AnaEE France is also investing in the shared instruments and analytical resources required for a detailed characterization of the environment and microorganisms. In a single integrated network it provides all the tools required to study, understand and model biological systems and conduct innovative biological research on gene - environment interactions, biodiversity and the functioning of ecosystems.
