Dubois, Stanislas / Orvain, Francis / Marin Leal, Julio César / Ropert, Michel / Lefebvre, Sébastien - 2007Oyster culture structures support a host of epibionts belonging to the same suspension-feeding guild, which are considered to be potential competitors for food with cultivated oysters. In an intertidal shellfish ecosystem on the northern French coast, an approach based on stable isotopes (C-13 and...Contributeur (s):

Leal, J / Dubois, Stanislas / Orvain, Francis / Galois, Robert / Blin, J / Ropert, Michel / Bataille, M / Ourry, A / Lefebvre, S - 2008Food sources for cultivated marine bivalves generally are not well identified, although they are essential for a better understanding of coastal ecosystems and for the sustainability of shellfish farming activities. In addition to phytoplankton, other organic matter sources (OMS), such as...Contributeur (s):

Dubois, Stanislas / Barille, Laurent / Cognie, Bruno - 2009Sabellaria alveolata is a tube-building gregarious polychaete that constructs large biogenic reefs. In macrotidal shellfish ecosystems, this species competes for food with cultivated suspension-feeders. The suspension-feeding activity and clearance rate of S. alveolata were investigated in response...Contributeur (s):

The honeycomb worm Sabellaria alveolata forms biogenic reefs which constitute diversity hotspots on tidal flats. The largest known reefs in Europe, located in the Bay of Mont-Saint-Michel (English Channel), are suffering increasing anthropogenic disturbances which raise the question of their...Contributeur (s):

Along the Louisiana, USA continental shelf, sandy shoals are shallow, possibly oxygen-rich "islands" surrounded by deeper muddy deposits prone to hypoxia. Shoals also contain significant quantities of fine sand that may be mined in the future for coastal restoration. The ecological role...Contributeur (s):

Callaway, Ruth / Desroy, Nicolas / Dubois, Stanislas / Fournier, Jerome / Frost, Matthew / Godet, Laurent / Hendrick, Vicki J. / Rabaut, Marijn - 2010Dense aggregations of tube-worms can stabilize sediments and generate oases for benthic communities that are different and often more diverse and abundant than those of the surroundings. If these features are to qualify as biogenic reefs under nature-conservation legislation such as the EC Habitats...Contributeur (s):

This study has exploited aerial photographs and LiDAR digital elevation model to quantify intertidal complex landforms volume. A first volume estimation of the main sabellariid polychaete reef complex of the Bay of Mont-Saint-Michel - France is presented. The Sabellaria alveolata is an engineering...Contributeur (s):

Desroy, Nicolas / Dubois, Stanislas / Fournier, Jerome / Ricquiers, L. / Le Mao, Patrick / Guerin, Laurent / Gerla, Daniel / Rougerie, Michel / Legendre, Aurelie - 20111. Reefs built by the annelid worm Sabellaria alveolata in the Bay of Mont-Saint-Michel (France) are the most extensive intertidal biogenic structures within Europe. Before and after mussel farming extensions, a study designed to provide a biological health index of the Sainte-Anne reef (223 ha)...Contributeur (s):

Haploops nirae is a gregarious tubiculous amphipod that uses its two pairs of antennae to filter particles from the water column. Recent sonar mappings of Haploops seabeds revealed that thousands of hectares of softbottom muddy sediments in South Brittany coastal ecosystems are now colonized by...Contributeur (s):

Blanchet, Aline / Dubois, Stanislas / Hily, Christian / Rochette, Sebastien / Le Goaster, Edouard / Guillou, Monique - 2012Mixed beds of Ophiocomina nigra and Ophiothrix fragilis (Echinodermata, Ophiuroidea) are usually predominated by O. fragilis and are reported to be stable over time. The Bay of Brest (Brittany, France) is a highly productive ecosystem where both species co-occur in the main central part. Using a...Contributeur (s):

Colombo, Francesca / Costa, Valentina / Dubois, Stanislas / Gianguzza, Paola / Mazzola, Antonio / Vizzini, Salvatrice - 2013Stable isotopes were used to investigate contributions of autochthonous (i.e. benthic: epilithon and macroalgae) and allochthonous (i.e. pelagic: phytoplankton) organic matter sources to the diet of suspension-feeders, grazers and predators associated to small reef-pools (cuvettes) created by the...Contributeur (s):

Ricquiers, Laurent / Desroy, Nicolas / Dubois, Stanislas / Guerin, Laurent / Gerla, Daniel / Legendre, Aurelie / Le Mao, Patrick / Rougerie, Michel - 2007L’état de santé du récif à Sabellaria alveolata de Sainte-Anne a été évalué afin de juger des conséquences des activités menées en baie du Mont Saint Michel (conchyliculture, pêche à pied…) sur ce patrimoine naturel remarquable. Un relevé de différents paramètres a été conduit en 2002 (Dubois, 2003...Contributeur (s):

Brind'Amour, Anik / Dubois, Stanislas - 2013Recently revisited, the concept of niche ecology has lead to the formalisation of functional and trophic niches using stable isotope ratios. Isotopic diversity indices (IDI) derived from a set of measures assessing the dispersion/distribution of points in the δ-space were recently suggested and...Contributeur (s):

Dubois, Stanislas - 2014Les espèces ingénieurs modifient et façonnent leur environnement. Elles jouent des rôles souvent clés dans la structure et le fonctionnement des habitats, notamment dans les environnements marins côtiers. A travers plusieurs modèles biologiques, choisis essentiellement parmi les espèces tubicoles,...Contributeur (s):
