δ 15 N Phe (circles) and δ 15 N Glx (squares) of eastern North Pacific (ENP) killer whale ecotypes (fish-eating residents and mammal-eating transients) and eastern Canadian Arctic/Northwest Atlantic (ECA/NWA) killer whales with tooth wear and no tooth wear (error bars = standard deviation).
Similar relative differences in δ 15 N Glx-Phe among the ECA/NWA groups as the ENP ecotypes suggest similar dietary divisions.
