| A checklist of macroalgae in Thau Lagoon (Herault, France), based on literature records and new collections, is given. Using present-day taxonomy, 196 taxa and stadia of macroalgae have been identified to date. Sixty of these were no longer found in the samples, 36 were new to the lagoon, and the taxonomic identity of 15 species was amended. Twenty-five new introduced taxa were identified, giving a total of 45 introduced macroalgae for the flora (23% of total). Among these, 17 taxa and several genera (Acrorhrix, Chondrus, Dasysiphonia (?), Prionitis) are new to the Mediterranean Sea and 12 are new to Europe. The majority (43 taxa) may originate from the Pacific region, having arrived either directly or via other aquaculture sites. A highly probable vector... |

| Microbes regularly contaminate Thau lagoon shellfish. Between 1997 and 2007, 18% of the analyses carried out in dry weather recorded more than 230 Escherichia coli / 100 g of bivalves (Ifremer French microbial monitoring network), leading the administration to restrict the shellfish harvest area, including suspension of production. This study aims to determine, the contribution of seabirds, which roost at night on the Thau lagoon shellfish growing frames, to shellfish faecal pollution in dry weather.Data were collected in 2008 from both the drainage area (pollution input) and the lagoon (water quality and microbial monitoring, seabird counts) in dry weather. The data showed that, with no watershed input or lagoon resurgence, microbial contaminants were... |
