Welcome to ECOSYS

UMR ECOSYS - Ecologie fonctionnelle et écotoxicologie des agroécosystèmes

Disciplinary groups

The laboratory is organized into three scientific groups:

Ecophysiology and physical chemistry of plant-atmosphere interactions (Eco&Phy)

  • Understanding and modelling agroecosystems functioning in interaction with biotic (pathogens, macrofauna, multispecies associations) and abiotic (low nitrogen levels, water, heat and oxidative stresses) factors;
  • Identification of the ecophysiological processes involved in the resilience of crops and their associated functional traits;
  • Quantification and prediction of biosphere-atmosphere exchanges of greenhouse gases, pollutants and particles, and the fate of nitrogen and pesticides from field to European scales beyond that of individual plots;
  • Integrated evaluation of food and energy crops systems, taking into account production, costs and environmental impacts. 

Soil Science

  • Optimization of the valorization of organic residues in agriculture;
  • Analysis of the fate, dispersion and environmental impact of pesticides and of other organic contaminants in agroecosystems;
  • Study of the dynamics of organic matter in soils and the mechanisms of carbon storage at diverse levels of spatial organization;
  • Consideration of the ecosystem services supplied by soils in multi-criteria assessment of cropping systems.


  • Characterization of exposure to contaminants, through studies of the dynamics of interactions between micropollutants and organisms in the soil, at different biological scales;
  • Understanding and modelling of the role of landscape elements on this exposure;
  • Studies of the long-term effects of low doses and mixtures of contaminants on soil organisms;
  • Development and validation of indicators of soil functioning and of the health of soil organisms (biomarkers, bioindicators).
  • Analysis of the contribution of ecotoxicology to the multicriteria evaluation of agroecosystem soils and the services they supply.
