Isotopic evidence of salmon, Oncorhynchus spp., in the diet of the Wolverine, Gulo gulo, on Princess Royal island, British Columbia

Abstract

Evidence from δ13C and δ15N isotope signatures from hair samples from a Wolverine, Gulo gulo, suggest the use of salmon, Oncorhynchus spp., in the diet of the Wolverine on Princess Royal Island on the north coast of British Columbia. This is also the first published record of Wolverines on that island.
