  abstract = {{T}he spatial variability of food resources along continental margins can strongly influence the physiology and ecology of benthic bivalves. {W}e explored the variability of food sources of the great scallop {P}ecten maximus, by determining their fatty acid ({FA}) composition along an inshore-offshore gradient in the {B}ay of {B}iscay (from 15 to 190 m depth). {T}he {FA} composition of the digestive gland showed strong differences between shallow and deep-water habitats. {T}his trend was mainly driven by their content in diatom-characteristic fatty acids, which are abundant near the coast. {S}callops collected from the middle of the continental shelf were characterized by higher contents of flagellate markers than scallops from shallow habitats. {T}his could be related to a permanent vertical stratification in the water column, which reduced vertical mixing of waters, thereby enhancing organic matter recycling through the microbial loop. {I}n the deeper water station (190 m), {FA} compositions were close to the compositions found in scallops from shallow areas, which suggest that scallops could have access to the same resources (i.e. diatoms). {M}uscle {FA} composition was more indicative of the physiological state of scallops over this depth range, revealing contrasting reproductive strategies among the two coastal sites and metabolic or physiological adaptation at greater depth (e.g. structural and functional adjustments of membrane composition). {T}his study therefore revealed contrasted patterns between shallow and deeper habitats for both {P}. maximus muscle and digestive gland tissues. {T}his emphasizes the variability in the diet of this species along its distribution range, and stresses the importance of analyzing different tissues for their {FA} composition in order to better understand their physiology and ecology.},
