Última Etude du biofilm microalgal des vasières intertidales : dynamique spatio-temporelle à micro-échelle et performances photosynthétiques ArchiMer Herlory, Olivier. The microalgal biofilm, which is present on sediment surface, is the primary production unit on bare intertidal mudlfats. In order to improve our understanding of this primary production system, a study was undertaken at microscale to analyse the structural and functional properties of this biofilm. In the first part of this work, a detailed descriptive analysis lead to the characterisation of the spatiotemporal dynamics of the physical structure of the biofilm. It turns out that the biofilm exhibits its own dynamics at the sediment surface (as a discrete compartment in the top 200 µm), but still has a functional relationship with the total available biomass (PCB) distributed within the top 1 cm (linear relationship between the maximum size of the biofilm...

The ecological quality status (EcoQ) of intertidal mudflats constrained by Pacific oyster farming was assessed by single (H', AMBI, BENTIX and BOPA) and multimetric (M-AMBI and average score) index approaches in the Pertuis Charentais (SW France). Fifteen sampling stations were monitored seasonally for sedimentological features and macrozoobenthos in 2004. Sediments affected by oyster biodeposits showed organic matter enrichment, and sediments from off-bottom culture sites had higher organic matter contents and lower redox potentials than sediments from on-bottom culture sites. Biotic indices consistently registered responses of macrozoobenthos to organic enrichment but there was only partial agreement between single index-derived EcoQs. The average score...
