First records of dusky grouper Epinephelus marginatus settlement-stage larvae in the Ligurian Sea ArchiMer
Faillettaz, Robin; Gilletta, Laurent; Petit, Franck; Francour, Patrice; Irisson, Jean-olivier.
The presence of dusky grouper Epinephelus marginatus settlement-stage larvae in the Ligurian Sea is reported. Epinephelus marginatus populations are slowly recovering along the french Mediterranean coast since the establishment of a moratorium on spearfishing in 1993 but still remain spatially restricted to marine protected areas. The occurrence of Epinephelus marginatus larvae in a region where effective settlement had not been detected for decades is a new observation supporting the species’ recovery.

In coastal systems, the multiplicity of sources fueling the pool of particulate organic matter (POM) leads to divergent estimations of POM composition. Eleven systems (two littoral systems, eight embayments and semi-enclosed systems and one estuary) distributed along the three maritime façades of France were studied for two to eight years in order to quantify the relative contribution of organic matter sources to the surface-water POM pool in coastal systems. This study was based on carbon and nitrogen elemental and isotopic ratios, used for running mixing models. The POM of the estuary is dominated by terrestrial material (93% on average), whereas the POM of the other systems is dominated by phytoplankton (84% on average). Nevertheless, for the latter...

In costal systems, particulate organic matter (POM) results from a multiplicity of sources having their respective dynamics in terms of production, decomposition, transport and burial. The POM pool experiences thus considerable spatial and temporal variability. In order to better understand this variability, the present study employs statistical multivariate analyses to investigate links between POM composition and environmental forcings for a panel of twelve coastal systems distributed along the three maritime regions of France and monitored weekly to monthly for 1 to 8 years. At multi-system scale, two main gradients of POC composition have been identified: a ‘Continent-Ocean’ gradient associated with hydrodynamics, sedimentary dynamics and depth of the...
