Trace metals, stable isotope ratios, and trophic relations in seabirds from the North Pacific Ocean
Abstract Trace elements including mercury, cadmium, selenium, and stable nitrogen isotope ratios (δ 15 N) were measured in tissues of Pacific seabirds. Two species of albatross ( Diomedea immutabilis, Diomedea nigripes ), four species of shearwaters ( Puffinus bulleri, Puffinus carneipes, Puffinus g...
