Trophic Levels Of North Pacific Humpback Whales (Megaptera Novaeangliae) Through Analysis Of Stable Isotopes: Implications On Prey And Resource Quality
Trophic levels of 1,105 humpback whales from six geographically and isotopically distinct North Pacific feeding groups were calculated using δ 15N of humpback whales and regional primary con-sumers. The overall mean trophic level for North Pacific humpback whales was 3.6 ± 0.02, indicating a diet of...
