In order to test the previously formulated hypotheses regarding mobility and resource procurement strategies practiced by Middle Holocene Glazkovo foragers in the Baikal region of Siberia, stable strontium isotope (87Sr/86Sr) analysis was applied to human remains from the Bronze Age Khuzhir-Nuge XIV cemetery. The main goal was to differentiate between two alternative models: one based on resource acquisition within a relatively large territorial range encompassing most of the Cis-Baikal area, and the other involving a smaller annual range mainly confined to specific micro-regions. A secondary goal was to explore inter-individual variability in strontium ratios, and potential sociocultural correlates. Interpretation of the human data involved assessment of the biologically available strontium isotope ratios, tissue biology, trophic level effect, species-specific Sr-catchment, composition of human diet, sharing of resources, and mobility-related technology. The results indicate a considerable degree of intra- and inter-individual variability in strontium isotope ratios and long-term foraging territories focusing on the west coast of Lake Baikal but including other parts of the Baikal region.
