Stable isotopes in Ctenomys bone collagen as proxies for Holocene climate and habitat change in the Monte Desert (Argentina)
The present study investigates the variability of both the δ 13 C and the δ 15 N stable isotopes in modern and archaeological Ctenomys rodents bone collagen. The purpose of this investigation is to assess the correlation of these isotopes with climate, and thereby reconstruct changes in the Holocene habitat of the Monte Desert. Firstly, the isotopic variability (δ13C and δ15N) in contemporary Ctenomys (post-1970 AD) bone collagen is evaluated in …
Isotopic study of lipids and collagen in bones from archaeological and modern ungulates for the study of paleodiets in Argentina
Species included in this study and their geographical provenance. • Lipids and collagen in ungulate bone specimens provide complementary information on whole diet and protein diet. • Carbon stable isotope offsets between lipids and collagen are variable for ungulate species. • Paired stable isotope values can address diet change, metabolic stress, and ungulate-human interactions. In this paper we carried out a sequential extraction of lipids and …
Dietary change of North Patagonian guanacos: A historical ecology perspective through the study of stable isotopes
This paper presents the results of a study on the isotopic ecology of guanacos in central western Argentina. We examine the historical population ecology of guanacos using stable isotope analysis of bone collagen from pre-Hispanic and modern guanaco populations ( n = 129), considering variability in two ecoregions: the Monte hot desert and the Andean-Patagonian cold desert. Our study addresses the consistency of guanaco diets over time, evaluatin…
Stable Isotope Composition (C and N) of Vegetation in Subtropical Andes: Piedmont ‘Anomaly’ and its Implications for Paleo (Ecology) and Human Diet Reconstruction
Isotope baselines are fundamental to infer diets, and to evaluate trophic relationships between humans, animals, and plants. In this study, we aim to detect spatial patterns of δ13C and δ15N of different plant types (C3, C4 and CAM) along environmental gradients in the eastern slopes of the southern Andes, in order to use them as a baseline to reconstruct animal diet, mobility, and trophic relations in the area. The stable isotope composition of …
