Strontium isotopes allow tracking the scale and pattern of movements of people and animals.With the ultimate goal of reconstructing human mobility in the southern Andes (Argentina andChile), we present isotopic values for rodent samples selected from the main geological units,thus contributing to building a macro-regional framework of bioavailable strontium. The resultsshow an important variation between geological units with little isotopic overlap between theyoung western Principal Cordillera (0.70393 ± 0.0005), Eastern Principal Cordillera (0.70563 ±0.0001), Frontal Cordillera (0.70670 ± 0.00087), and the old Precordillera (0.70946 ± 0.00073)east of the Andes. This substantiates the potential of this approach for archaeological andpaleoecological analyses in the southern Andes. We also present the first set of isotopicresults for wild and domesticated camelids from the southern Andes, suggesting that homeranges were similar. We reconsider published results for human samples from the last 2000years in Mendoza Province (Argentina), a period characterised by intense socio-economicchange. The observed pattern suggests little systematic human mobility between geologicalregions across the Andes. While this may not necessarily indicate low mobility, it clearly goesagainst scenarios of high residential mobility, as suggested on the basis of other isotopesystems.
