Diet consistency but large-scale isotopic variations in a deep-sea shark: the c...
Besnard, Lucien; Duchatelet, Laurent; Bird, Christopher S.; Le Croizier, Gaël; Michel, Loïc; Pinte, Nicolas; Lepoint, Gilles; Schaal, GauthierDeep-sea elasmobranchs are commonly reported as bycatch of deep-sea fisheries and their subsequent loss has been highlighted as a long-running concern to the ecosystem ecological functioning. To understand the possible consequences of their removal, information on basic ecological traits, such as diet and foraging strategies, is needed. Such aspects have been widely studied through stomach content analysis but ...
A 15-month survey of Dimethylsulfoniopropionate and Dimethylsulfoxide content i...
Richir, Jonathan; Champenois, Willy; Engels, Guyliann; Abadie, Arnaud; Gobert, Sylvie; Lepoint, Gilles; Silva, João; Santos, Rui; Sirjacobs, DamienPosidonia oceanica is the only reported seagrass to produce significant amount of dimethylsulfoniopropionate (DMSP). It is also the largest known producer of DMSP among coastal and inter-tidal higher plants. Here, we studied (i) the weekly to seasonal variability and the depth variability of DMSP and its related compound dimethylsulfoxide (DMSO) in P. oceanica leaves of a non-disturbed meadow in Corsica, France...
Ontogenic variation and effect of collection procedure on leaf biomechanical pr...
de los Santos, Carmen B.; Vicencio-Rammsy, Bárbara; Lepoint, Gilles; Remy, François; Bouma, Tjeerd J.; Gobert, SylvieLeaf mechanical traits are important to understand how aquatic plants fracture and deform when subjected to abiotic (currents or waves) or biotic (herbivory attack) mechanical forces. The likely occurrence of variation during leaf ontogeny in these traits may thus have implications for hydrodynamic performance and vulnerability to herbivory damage, and may be associated with changes in morphologic and chemical ...
