“…Climate change affects human behaviour in many ways, but in agrarian societies such as the prehispanic Pueblo peoples inhabiting these two study areas-who derived B70% of their dietary biomass from maize 17 -its most direct ARTICLE NATURE COMMUNICATIONS | DOI: 10.1038/ncomms6618 influence is on agricultural productivity. Therefore, we convert our paleoclimate reconstructions into estimates of the spatial extent of the rain-fed maize agricultural niche within each landscape.…”

“…And yet, with limited recent exceptions (e.g. Ambrose et al, 2003;Kellner and Schoeninger, 2007;Arcini et al, ;Coltrain and Janetski, 2013;Colonese et al, 2014;Fernandes et al, 2012aFernandes et al, , 2014Ugan and Coltrain, 2012), the paleodietary reconstruction facilitated by this analysis has been limited to relative statements about source contributions (e.g. more of food X, less of food Y).…”

“…Even those recent studies that have made use of Bayesian mixture modeling methods of the sort employed here (Arcini et al, 2012;Fernandes et al, 2012aFernandes et al, , 2014Ugan and Coltrain, 2012;Coltrain and Janetski, 2013;Colonese et al, 2014), have not provided an experimentally derived means by which to calculate this value. The method shown above represents a first step towards that goal.…”

“…Sample sizes are small and no significant differences in δ 13 C or δ 15 N exist between age categories. However not surprisingly, subadults express the most enriched mean δ 15 N value (21.0 ± 1.2‰) among the three age categories, since a subset of these individuals was likely either nursing or recently weaned (Coltrain and Janetski, 2013;Katzenberg et al, 1996).…”

a b s t r a c tCoastal erosion on the Point Barrow, AK, spit necessitated salvage excavation of the Nuvuk cemetery. Purified bone collagen extracted from 54 Thule era burials was analyzed for stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopes values and accelerator radiocarbon dated. The highly enriched nitrogen isotope chemistry of these burials indicates the Nuvuk were apex marine predators with heavy reliance on high trophic level marine taxa, primarily beluga whales and ringed and bearded seal. Bowhead whaling made a less significant contribution to sampled diets despite its social currency. In contrast, carbon isotope values suggest significant terrestrial inputs to Nuvuk diets. Comparative data from Aleutian and eastern Arctic marine foragers further confound what appear to be conflicting results. Yet modern polar bear along the Beaufort Sea shelf show isotopic patterning very similar to that of the Thule at Nuvuk. We suggest that depleted Nuvuk δ 13 C values result primarily from the discharge of riverine, terrigenous carbon into the Beaufort Sea during spring, freshwater runoff. The deposition of large amounts of terrigenous carbon prior to the melting of landfast ice contributes to an isotopically deleted estuarine-like, near-shore food web. A local ΔR correction to marine reservoir effect was used to calibrate AMS radiocarbon dates. Results are supported by paired two-sigma age ranges on burials and associated terrestrial grave materials.
