Reduced Population Variance in Strontium Isotope Ratios Informs Domesticated Turkey Use at Chaco Canyon,New Mexico,USA

Traditionally, strontium isotopes (⁸⁷Sr/⁸⁶Sr) have been used as a sourcing tool in numerous archaeological artifact classes. The research presented here demonstrates that ⁸⁷Sr/⁸⁶Sr_bioapatite ratios also can be used at a population level to investigate the presence of domesticated animals and methods of management. The proposed methodology combines ecology, isotope geochemistry, and behavioral ecology to assess the presence and nature of turkey (Meleagris gallopavo) domestication. This case study utilizes ⁸⁷Sr/⁸⁶Sr_bioapatite ratios from teeth and bones of archaeological turkey, deer (Odocoileus sp.), lagomorph (Lepus sp. and Sylvilagus sp.), and prairie dog (Cynomys sp.) from Chaco Canyon, NM, USA (ca. A.D. 800–1250). Wild deer and turkey from the southwestern USA have much larger home ranges and dispersal behaviors (measured in kilometers) when compared to lagomorphs and prairie dogs (measured in meters). Hunted deer and wild turkey from archaeological contexts at Chaco Canyon are expected to have a higher variance in their ⁸⁷Sr/⁸⁶Sr_bioapatite ratios, when compared to small range taxa (lagomorphs and prairie dogs). Contrary to this expectation, ⁸⁷Sr/⁸⁶Sr_bioapatite values of turkey bones from Chacoan assemblages have a much lower variance than deer and are similar to that of smaller mammals. The sampled turkey values show variability most similar to lagomorphs and prairie dogs, suggesting the turkeys from Chaco Canyon were consuming a uniform diet and/or were constrained within a limited home range, indicating at least proto-domestication. The population approach has wide applicability for evaluating the presence and nature of domestication when combined with paleoecology and behavioral ecology in a variety of animals and environments.     

China's regional policies: how much hegemony?1

China is commonly assumed to be seeking hegemony in its region. Yet China's region involves it in relationships with major states with their own hegemonic or leadership interests—the US, Russia, Japan and India. This article examines each of China's regional relationships in terms of the prime interests of China's foreign policy framework. It concludes that it is important to distinguish between hegemonic capabilities and intentions: that while China will want to extend its influence as a regional power, its capability to do that will continue to grow in each of its subregions, its ability to exercise that power and influence will be limited. In the past its efforts have been largely to seek secure borders and economic opportunities and that for some years those objectives, together with energy security, are likely to remain the priority.     

Investigating the likelihood of a reservoir offset in the radiocarbon record for ancient Egypt

Some radiocarbon dates for ancient Egypt have been significantly offset from the established historical chronology (see Bonani et al., 2001). In this paper, short-lived plant species collected in Egypt between 1700 and 1900 AD were used to investigate the possibility that the radiocarbon record had been influenced by reservoir effects. AMS radiocarbon measurements were made on 66 known-age samples, resulting in an average offset from expected values of 19 years. The implications of this minor discrepancy on the likelihood of a reservoir process are discussed, and the agreement of the data with recent models of radiocarbon seasonality is also considered.     

Negotiating hydro-scales,forging states: Comparison of the upper Tigris/Euphrates and Jordan River basins

In this comparative study of two water basins in the Middle East, we examine the hydro-political construction of scale as central to state and nation building, and their territorial consolidation. We argue that scalar negotiations and constructions of freshwater became central to the very consolidation of both Turkey and Israel. The examples we offer also illustrate the usefulness of a performative approach to scale, benefiting from but moving beyond a politics of scale approach. The comparative focus on hydro-scalar politics and performativities in relation to state and nation building offered a) lends to an enriched understanding of water politics in these two contested river basins, b) enables fuller understanding of how water becomes central to the processes by which nations, states, and territories are consolidated in this region, and c) contributes to recent debates in political geography by demonstrating the value of scalar and performative approaches. Underscoring these linkages, the analysis differs from many works on water in the Middle East, contributes to studies of state and nation building as contested processes, and avoids the assumption of state or national scales as ontological pre-givens.     

South Carolina Shipyards: Labour,Logistics, Lumber and Ladies

Southern shipyards, like Hobcaw and Mars Bluff, were established at locations chosen primarily for convenient access to transportation networks, building materials, clientele and labour. The historical record reveals a home front role played by local plantation owners and slaves as shipyard labour. Women served as project fundraisers, shipyard dilettantes, shipwright’s wives and possibly slave mistresses with a paucity of material culture to confirm their presence in the archaeological record. Archaeological investigations on land and underwater yield evidence of artefacts associated with diet, shipbuilding, warfare and ethnicity.
