BACKGROUND Cephalopods play a major role in marine ecosystems, but knowledge of their feeding ecology is limited. In particular, intra- and inter-individual variations in their use of resources has not been adequatly explored, although there is growing evidence that individual organisms can vary considerably in the way they use their habitats and resources.(More)
The link between trophic ecology and metal accumulation in marine fish species was investigated through a multi-tracers approach combining fatty acid (FA) and stable isotope (SI) analyses on fish from two contrasted sites on the coast of Senegal, one subjected to anthropogenic metal effluents and another one less impacted. The concentrations of thirteen(More)
Spatial variations in carbon and nitrogen stable isotopes (d13C and d15N) of benthic filter feeders were investigated on an inshore-offshore gradient (0e250 km) along the continental shelf of the northern Bay of Biscay (NE Atlantic Ocean). d13C and d15N values were measured in muscle tissues of four filter-feeding mollusc species (epifaunal: Pecten maximus,(More)
Age estimates, typically determined by counting periodic growth increments in calcified structures of vertebrates, are the basis of population dynamics models used for managing exploited or threatened species. In fisheries research, the use of otolith growth rings as an indicator of fish age has increased considerably in recent decades. However, otolith(More)
