Monthly mobility inferred from isoscapes and laser ablation strontium isotope ratios in caprine tooth enamel.

ABSTRACT: Strontium isotopic analysis of sequentially formed tissues, such as tooth enamel, is commonly used to study provenance and mobility of humans and animals. However, the potential of ⁸⁷Sr/⁸⁶Sr in tooth enamel to track high-frequency movements has not yet been established, in part due to the lack of data on modern animals of known movement and predictive model of isotope variation across the landscape. To tackle this issue, we measured the ⁸⁷Sr/⁸⁶Sr in plant samples taken from a 2000 km² area in the Altai Mountains (Mongolia), and the ⁸⁷Sr/⁸⁶Sr in tooth enamel of domestic caprines whose mobility was monitored using GPS tracking. We show that high-resolution, sequential profiles of strontium isotope composition of too
