Since the mid-20th century, Mediterranean lagoons have been affected by eutrophication, leading to significant changes in primary producers. In the early 2000s, management actions have been implemented to reduce nutrient inputs with the aim to achieve a good ecological status as requested by the EU water framework directive. As a result of these actions, a sharp decline in nutrient loads has been recorded in several lagoons leading to an oligotrophication of the water column. The analyses of a long-term data set (1998-2015) of 21 polyhaline and euhaline lagoons with contrasting trophic status allowed us to infer a general scheme for the changes in macrophyte assemblages during the oligotrophication process. Placing hypertrophic and oligotrophic conditions...

By the end of the 20th century, many of the coastal lagoons along the French Mediterranean coast showed insufficient water quality and degraded ecosystem states due to anthropogenic impacts. Among these, nutrient over-enrichment, resulting in eutrophication, has been a major concern. The EU Water Framework Directive (WFD) has initiated public action to improve their water quality and ecosystem state using an approach rooted in restoration ecology. Here we analyze how this has been applied for the coastal lagoons in South France, considering eutrophication as an example of ecosystem degradation and oligotrophication as the corresponding trajectory for ecological restoration of the eutrophied coastal lagoons. Oligotrophication trajectories, initiated by the...

Rôle des macrophytes dans la restauration des milieux lagunaires : successions écologiques
Provedor de dados: 5
Autores: 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...

Etude de Ruppia cirrhosa dans la lagune de Canet‐St‐Nazaire
Provedor de dados: 5
Autores: Oheix, Jocelyne; Ouisse, Vincent; Munaron, Dominique; Le Fur, Ines; Derolez, Valerie.
L'herbier de Ruppia cirrhosa a connu des périodes de fortes régressions et de reprises dans la lagune de Canet-St-Nazaire. Pour mieux comprendre ces fluctuations, une étude bibliographique de la physiologie de la phanérogame Ruppia cirrhosa est réalisée, associée à l'analyse des données disponibles dans la lagune de Canet (acquises notamment dans le cadre du Réseau de Suivi Lagunaire). Les éléments influant sur le développement ou la régression de Ruppia cirrhosa sont étudiés à la lumière des connaissances bibliographiques. L'eutrophisation et la contamination chimique, associées à des paramètres environnementaux parfois défavorables ont pu contribuer au déclin de l'herbier après 2002. Les conditions qui ont permis la reprise de l'herbier à partir de 2011...
