  abstract = {{T}here have been several studies where the isotopic composition of organisms has been determined seasonally, but fewer have examined separate organs. {I}n this context, separate organs (e.g. gonad, digestive gland and muscle), of a suspension-feeder, the scallop {P}ecten maximus, were used to assess seasonal changes of both stable isotopes and biochemical components. {O}ur study used multiple indicators (stable carbon and nitrogen isotopes ratios, biochemical components and seston {C}hl a) to track nutritive activity and energy allocation in {P}. maximus from the {B}ay of {B}rest ({F}rance). {I}n addition to seasonal variation in the isotopic composition of {P}. maximus tissues, we found strong differences in the mean isotopic signatures of different organs. {T}his has serious implications for interpretation of animal diets and potential use in animal physiology. {F}urthermore, we present evidence that seasonal variations of metabolism will cause changes in the isotopic composition not related to changes in the diet. {I}nterpretation of isotopic data may require consideration of values from several separate organs. {F}inally, ?15{N} appears powerful to track metabolite fates in the scallop {P}. maximus.},
