We generated 10 high-resolution profiles of stable carbon and oxygen isotope values (δ13Coto and δ18Ooto) of sagittal otoliths of whitefish (Coregonus lavaretus) from Lake Annecy (France) to determine the factors that control intra-individual δ13Coto variation. Dominant patterns of intra-otolith variation compared well with seasonal and age-specific respiration modeling. Conversely, intra-otolith variation of δ13C values did not compare well with measured dietary and environmental variation. We… CONTINUE READING
