Oxygen isotope ratios (δ¹⁸O values) of hair largely reflect features of regional hydrology while strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) are thought to reflect bedrock geology; combination of both isotope signatures may provide greater capacity for determining provenance and reconstructing travel history of an organism. To test this hypothesis, we compared the O-Sr isotope profiles of hair from domestic horses with known residency histories.
