Work in progress

Scientific interests

Preliminary data indicates :

  • Impacts of flood regulation on biota and

ecosystem functions

  • Significant effect of floods and fish presence

in ecosystem functions Work to be done:

  • Estimation of the effects of floods on

ecosystem services Functioning of freshwater ecosystems Biodiversity Ecosystem processes Global change
