Stable isotope and trace element status of subsistence-hunted bowhead and beluga whales in Alaska and gray whales
Abstract Tissues of bowhead, beluga, and gray whales were analyzed for Ag, Cd, Cu, Se, Zn, THg and MeHg (belugas only). d 15 N and d 13 C in muscle were used to estimate trophic position and feeding habitat, respectively. Trace element concentrations in tissues were significantly different among wha...
