Isotopic distribution for 14 examined Broken Group Island dogs in comparison with regional archaeological isotope values. Model A1 includes terrestrial mammals, Model B1 focuses exclusively on the isospace of marine animals, while Model C1 excludes shellfish. We applied trophic discrimination factors of 1.0‰ for δ13C and 3.6‰ for δ15N to dog isotope values to correct for isotopic discrimination between consumers and food sources9,31,32.
