Dietary studies in marine mammals are traditionally performed by stomach contents analyses, which may be insufficient to determine long-term dietary preferences of these upper level predators. Our primary objective was to test the efficiency of trace metal measurements as comple- mentary tools in dietary studies. Variations in cadmium (Cd) exposure through the diet and its effec- tive renal levels in the short-beaked common dolphin Delphinus delphis were investigated to study the long-term… CONTINUE READING
