The development of isotopic baselines for comparison with paleodietary data is crucial, but
often overlooked. We review the factors affecting the carbon (δ13C) and nitrogen (δ15N) …

The debate regarding the susceptibility of bone and enamel carbonate to preserve in vivo
carbon isotope ratios is as old as paleodietary research. After more than three decades of …

This paper explores variation in maize consumption among human societies in arid
environments of central-western Argentina over the last 2500 years. Increasingly positive …

Palaeodietary isotope studies have long assumed C 4 signals in South American
archaeological populations to be due to the consumption of maize (Zea mays), which in turn …

This paper discusses the problems faced when making interpretations of human stable
isotope values due to the various explanatory alternatives that arise when reading …

This paper explores the relationships between population change and human diet after the
adoption of domesticated resources in northwest Mendoza, a subregion of central western …

Central western Argentina is the southern boundary of prehispanic maize in the
archaeological record. This paper explores the stable isotope information from human bone …

Prey ranking of animal resources is critical to the evaluation of decision-making of past
foragers. Previous work in Central Western Argentina (CWA) has used a ranking of …

Dietary patterns at two Bronze Age sites in the Hexi Corridor are investigated by the analysis
of stable carbon and nitrogen isotopes in faunal bone collagen. The findings are compared …

This paper reviews the significant advances in isotopic investigations in Andean South
America and directs scholars to explore new theoretical and analytical directions …
