Paleodiets of hunter-gatherers from the central Patagonian coast: Reviewing scopes and limitations of stable isotope analyses
This work reviews paleodietary reconstructions of hunter-gatherers from the northeast province of Chubut, Argentina. The isotopic record of human bone can complement information from zooarchaeological and technological studies with its particular resolution on the long-term diet of individuals. Previous δ13C and δ15N studies found dietary differences between the coastal area and the lower basin of the Chubut River, both in the proportion of marine resources in the diet and the trophic positions of prey. However, it is challenging to test hypotheses concerning human diets in northeastern Patagonia, where C3 and CAM plants grow and terrestrial, riverine, and marine prey are available. Here, we focus on the local isotopic ecology to assess the scopes and limitations of δ13C and δ15N stable isotopes analyses. We provide new data on native faunas spanning different trophic levels of terrestrial, riverine, and marine environments. After establishing the basic patterns in the local isotope record, we reanalyze the available δ13Ccol, δ15N, and δ13Capa measurements from 23 individuals studied 15 years ago. That analysis reveals a relatively continuous distribution of several overlapping resources on the coast of northeastern Patagonia. Bayesian mixing models identified a combination of terrestrial and riverine resources aggregated as the main component of long-term diets. However, it generated diffuse estimations. The Bayesian ellipses, describing isotopic niches, emphasized more the spatial variations in diet between coastal and valley groups.
期刊介绍:
The aim of the International Journal of Osteoarchaeology is to provide a forum for the publication of papers dealing with all aspects of the study of human and animal bones from archaeological contexts. The journal will publish original papers dealing with human or animal bone research from any area of the world. It will also publish short papers which give important preliminary observations from work in progress and it will publish book reviews. All papers will be subject to peer review. The journal will be aimed principally towards all those with a professional interest in the study of human and animal bones. This includes archaeologists, anthropologists, human and animal bone specialists, palaeopathologists and medical historians.
