Ecology of aquatic plant communities and impact of multiple pressures


Within the EABX unit, the research of the ECOVEA team (ecology of aquatic plant communities and impact of multiple pressures) focused on understanding the biodiversity and functioning of plant communities (macrophytes, phytoplankton, phytobenthos) in rivers and lakes, as well as their responses to natural and anthropogenic disturbances. The team's research activities are organized around the following themes: assessment of exposure to contaminants, impact on plant communities at different levels of biological organization, biodiversity, vulnerability and adaptation to global changes. On an operational level, this research aims to produce tools for the diagnosis of the chemical and ecological status of water bodies.

Fields of research

Through in situ, experimental or data analysis approaches, the team conducts research aimed at:

  • understanding the factors underlying the spatial and temporal dynamics of biodiversity (taxonomic and functional) of freshwater plant communities, taking into consideration potential biotic interactions and the dispersal capacity of organisms ;
  • assessing the exposure of phytocenoses to anthropogenic pressures in the environment and characterize exposure-effect relationships at different levels of biological organization. This in order to :
    • assess the vulnerability and viability of aquatic plant communities to the different abiotic (contaminants) and biotic (invasive species) factors that occur in the context of global change ;
    • produce innovative operational tools for the diagnosis of the ecological (bioindicators), chemical and ecotoxicological (passive sampling, biomarkers) status of aquatic ecosystems (assessment of the initial state, restoration).


The identity of the team is based on a strong interdisciplinarity combining environmental chemistry, ecotoxicology and community ecology. We also have skills in data analysis and statistical modeling.
