Última Réseau de Suivi Lagunaire du Languedoc-Roussillon. Bilan des résultats 2002 ArchiMer Laugier, Thierry; Fiandrino, Annie; Souchu, Philippe; Benau, Laurent. The numerous coastallagoons lining the Languedoc-Roussillon mediterranean coast undergone high anthropic pressure. The Lagoon Monitoring Network as a result of partnership between Ifremer, the Languedoc- Roussillon Regional Council and the Rhône Méditerranée Corse Water Agency, apply to provide yearly a diagnostic of the environmental quality of21lagoons. This network has two main goals: • The monitoring of the state of the lagoon with regards to eutrophication and sorne specifie survey in coordination with local managers. • Management support (model simulation, synthetic infonnation, scientific support) towards local managers. This annual report gathers results of the actions planned in 2002 within the Network : • For each lagoon excosystem, results of...

A cross-ecosystem comparison of data obtained from 20 French Mediterranean lagoons with contrasting eutrophication status provided the basis for investigating the variables that best predict chlorophyll a (Chl a) concentrations and nutrient limitation of phytoplankton biomass along a strong nutrient enrichment gradient. Summer concentrations of dissolved inorganic nitrogen (DIN) and phosphorus (DIP) comprised only a small fraction of total nitrogen (TN) and total phosphorus (TP). On the basis of inorganic nutrient concentrations, the most oligotrophic lagoons appeared to be phosphorus-limited, with a tendency towards the development of nitrogen limitation as eutrophication increased, as evidenced by decreasing DIN:DIP ratios. A weak but significantly...

We explored the role of natural and anthropogenic environmental perturbations in shaping the community structure and dynamics of pico- and nanophytoplankton in coastal waters. The distribution patterns of phycoerythrin-rich picocyanobacteria (PE-CYAN) and phycocyanin-rich picocyanobacteria (PC-CYAN), autotrophic picoeukaryotes (PEUK) and nanophytoplankton (NANO) were examined over a period of 3 yr in 24 Mediterranean coastal lagoons displaying wide trophic gradients (from 0.2 to 630 mu g chlorophyll a [chl a] l(-1)) and salinity gradients (from fresh to marine waters). In summer, picoplanktonic abundances reached 3 x 10(8) cells l(-1), 5 x 10(9) cells l(-1) and 6 x 10(10) cells l(-1) for PE-CYAN, PC-CYAN and PEUK, respectively. PE-CYAN and PC-CYAN showed...
