Аннотация:The purpose of this work is to summarize and analyze all data on the composition of stable isotopes in human remains from the Bronze Age sites in the Pre-Urals region, as well as to draw preliminary conclusions about the diet of these groups. About 30 samples are at our disposal, covering a very long period (from the end of the 4th to the begging of the 1st-millennium cal BC). Despite a small sample size, some important conclusions can be drawn. First, livestock products were stapled foods of all cultural groups. Evidence for the fish consumption and related reservoir effect was diagnosed only in some individuals. Second, the scatter of values for the early period (the Yamnaya culture) correlates with a mobile lifestyle and animal husbandry. On the contrary, for the Late Bronze Age (the Srubnaya and Alakul cultures), we see very similar values of nitrogen and carbon isotopes within one locus, including cases of long-term residence of the collectives in these places (according to the 14C data). This is probably due to the stability of the subsistence and settlement systems (stationary settlements). Finally, the obtained results differ from the previously obtained data for the adjacent territory (the Southern Trans-Urals). Interpreting this conclusion requires expanding the analysis base, including collecting the information on stable isotope values from the natural reservoirs.
