  • 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.

  • Long term study of mixed forest of Pinus halepensis and Quercus ilex 55. Currently focused on carbon and water cycles, with routine measurements at the soil, plant, and ecosystem levels. Ecosystem manipulation consists in rainfall reduction and irrigation. Site is composed of : - a main enclosed area of 80x80 m ; - a 16 m tower supporting weather and eddy covariance measurements (ICOS level 2) - four 25x25 m plots (two inside and two outside the enclosed area) for 30% rainfall exclusion (with gutters), irrigation, control, and control with reversed gutters. In all plots, measurements are carried out for soil moisture, sap flow, stem diameter growth, leaf area index, litterfall, leaf water potential, and soil respiration.
