Foddering by Mongolian pastoralists is recorded in the stable carbon (δ13C) and nitrogen (δ15N) isotopes of caprine dentinal collagen

Possible ideas on carbon and nitrogen trophic fractionation of food chains: a new aspect of food‐chain stable isotope analysis in Lake Biwa, Lake Baikal, and the Mongolian grasslands

“…It is generally recognized that adult individuals of Baikal seal feed on fish such as Comephorus dybowskii (Yoshii et al 1999) and thus, the trophic level of infant or prenatal stages of mammals might look even higher than that of the adult individuals. This is consistent with previous reports about the d 15 N enrichment observed in infant stage of mammals (Balasse et al 2001;Balasse and Tresset 2002;Dalerum et al 2007;Makarewicz and Tuross 2006). We consider their quasi-high trophic level is due to their nutrition taken via milk or placenta of their mothers.…”

Stable isotope evidence for salt-marsh grazing in the Bronze Age Severn Estuary, UK: implications for palaeodietary analysis at coastal sites

“…Numerous studies have utilised carbon and nitrogen stable isotope analysis to investigate animal management in the past. These range from the characterisation of feeding strategies with isotopically distinct fodder, such as seaweed or millet (Pechenkina et al, 2005) and the inference of dairying from isotopic data for the weaning age of cattle (Balasse and Tresset, 2002), to reconstructions of the proportions of C 3 and C 4 plants in animal diet and their implications for transhumance (Balasse, 2002;Makarewicz and Tuross, 2005;Zazzo et al, 2005). Although modern, experimental studies can utilise a range of biological tissues (e.g.…”

Carbon and Nitrogen Stable Isotope Values for Plants and Mammals in a Semi-Desert Region of Mongolia

“…Khozu et al (2009) described the variation in isotope signatures across trophic levels at two study sites (Gachuurt, Ulaanbaatar and Khangai, Arkhangai aimag). Makarewicz & Tuross (2006) also explored the difference in livestock and wild ungulate isotopes due to diet. Thompson et al (2010) focused on the variation in human isotope values across Asia, including central Mongolia.…”
