Última Rôle des macrophytes dans la restauration des milieux lagunaires : successions écologiques ArchiMer Le Fur, Ines. The growing awareness of the negative impacts of the degradation of the water quality in coastal lagoons because of eutrophication has resulted in public action aiming at the reduction of the nutrient loadings into these lagoons. Hence, some of these coastal lagoons are currently undergoing ecological restoration and have shown a clear improvement of their water quality linked to decreasing phytoplankton biomass in the last 10 years. However, the response of the benthic macrophytes appears more complex, particularly by showing non-linear behaviour. By using complementary approaches including statistical analyses of long-term observations (1998-2015) and in situ measurements, this thesis aims to describe the dynamics of the macrophytes in space and time and...

Les objectifs de résultats, en termes de préservation ou de restauration des milieux aquatiques, que fixent la Directive Cadre sur l’Eau (2000/60/CE), nécessitent de connaître les liens entre l’état des masses d’eau et les pressions auxquelles elles sont soumises. L’évaluation de l’état des lagunes méditerranéennes est notamment basée sur différents éléments de qualité biologique (phytoplancton, macrophytes, macrofaune benthique de substrat meuble). La présente étude s’applique à recenser les pressions anthropiques sur les lagunes méditerranéennes, les bancariser et analyser les liens entre les indicateurs de qualité biologique de la DCE et des indicateurs de pressions pertinentes issus de ce recensement. Le travail d’identification des pressions et de... Tipo: Text Palavras-chave: Pressions; Lagunes méditerranéennes; Lien état-pression; DCE.

Located at the interface between marine and continental systems, coastal lagoons are among the most diverse and productive ecosystems. These semi-enclosed ecosystems are very vulnerable to nutrient enrichment. In the Languedoc-Roussillon region, anthropogenic pressures have profoundly damaged the coastal lagoons, especially those belonging to the Palavasian complex close to Montpellier. The latter lagoons have been affected by high nutrient loadings from the sewage treatment plant of the Montpellier agglomeration. This resulted in a trophic gradient among the eight lagoons in the complex, from mesotrophy to hypertrophy, with altered primary producer communities by favoring the predominance of the phytoplankton compartment.The phytoplankton responds very...
