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.     

Suicidal journeys: attempted suicide as geographies of intended death

In geography, a conversation around suicide survivors and their suicidal journeys has yet to happen. The current prioritisation of suicide as end points marked on maps and patterns of death in space and regions has obscured the lived experience of adults who attempt suicide and do not die. In an effort to reduce this invisibility, evidence derived from in-depth interviews with adults (18 years and over reported as missing) who freely delivered narratives of their attempts is employed to understand the complex spatiality of suicide in retrospect. Situating suicide survivors as knowledgeable about their feelings, beliefs and experiences, the paper encounters testimonies of intended death via a focus on spatialised journeys: physical routes, pathways and places of attempted suicide. Discussing these particular journeys as socio-spatial process represents the potential for geographical scholars to rework geographies of dying and (attempted) death as an active practice.     

Age-dependent bone loss in the femur in a medieval population

Age-dependent bone loss in femurs in a medieval skeletal assemblage from Wharram Percy, England was studied. Dual energy X-ray absorptiometry (DXA) was used to measure bone mineral density (BMD) in the proximal femur; radiogrammetry was used to measure cortical index (FEMCI) at the femur mid-shaft. Age-related loss of BMD was found in the proximal femur in both sexes. Females but not males showed loss of FEMCI. Patterning in bone loss with respect to age, sex and site in the skeleton resembled that seen in recent subjects. In this respect the results are similar to those of a previous study of metacarpal cortical bone in the same archaeological assemblage. Given the large difference in lifestyles, and that lifestyle factors are widely held to influence the severity of bone loss in osteoporosis, the similarities between the medieval and modern populations in the patterns of bone loss are surprising. These findings support those from an earlier study of these skeletons in calling into question the role of lifestyle factors in influencing the severity of bone loss in osteoporosis. © 1998 John Wiley & Sons, Ltd.     

Further aspects of fur trade life depicted in the skeleton

Osteobiographies were reconstructed from the skeletal remains of four adults from Fort Edmonton, a 19th century trading post of the Canadian fur trade. Three males were Caucasoid and probably ethnic Scots, given the usual origin of fur traders in this region. The lone adult female in the sample was Mongoloid, either Indian or Métis, and likely the ‘country wife’ of a fur trader, since she was buried in the European tradition in the fort cemetery. The cause of death is not discernible from any of the skeletal remains and none of these individuals exhibit any evidence of chronic infectious disease, malnutrition or neoplasia. Trauma, arthritis and other indicators of physical stress do appear, however, and present an opportunity to expand our understanding of the effects of fur trade life on the skeleton. Viewed in the context of historical accounts of life at the fort in the early 19th century, stress markers on the skeletons of three males have led to the conclusion that they were voyageurs who engaged in trading trips by canoe or boat. Lesions of the capsule attachment area at the proximal tibio‐fibular articulation appear unilaterally in two males and may be associated with ‘mushing’ or driving a dog sled in winter. The musculoskeletal lesions on the one preserved female skeleton are consistent with the arduous domestic activities documented at the fort, which include milking cows, churning butter, stirring lye soap, and harvesting grain and root vegetables by hand. Since specific occupations or behaviours cannot be precisely determined from muscular attachment and other stress markers, these interpretations are made cautiously and only in the culture‐historical context of the skeletal sample.

Cheating on climate change? Australia's challenge to global warming norms

The international governance of climate change was initially informed by two norms concerning who should take responsibility for mitigating climate change and how such mitigation should be pursued.1 1. These normative debates have also been analysed by Matthew J. Hoffman and Loren Cass (see Hoffman 2005; Cass 2006). View all notes Since the early 1990s, these norms have been contested by several states. In this article the author argues that such contestation is a product of the perceived incongruence between these norms and the domestic conditions of those states they seek to govern. Following an overview of the emergence and contestation of climate governance norms, the author elaborates on this relationship between international norms and domestic conditions. These theoretical assumptions are then explored in the context of Australia's response to international climate governance norms from the late 1980s to 2007. As the author demonstrates, the perceived incongruence of these norms with domestic conditions led Australia's foreign policy makers to contest the norms and focus on the construction of alternative governance processes by reframing the issue of climate change. Through a diversion of attention away from historical emissions to future emissions and possible technological mitigation options, climate governance was temporarily reconciled with Australia's domestic conditions. However, the author suggests that this came at the expense of international equity and long-term national sustainability.     

Obsidian hydration dating by infrared spectroscopy: method and calibration

Low temperature (90–190 °C) hydrothermal experiments have been conducted on seven obsidians where composition of the glass varies significantly in the concentration of structural water within the unhydrated bulk material. Infrared transmission spectroscopy was used to track the diffusion of molecular water into the glass surface as a function of time and temperature. Long-term (60–360 days) hydration sequences at 90 °C show a t^0.6 time dependence for the mass uptake of molecular water that forms the hydration layer. The structural water concentration of the unhydrated bulk obsidian is highly correlated with the pre-exponential and activation energy and may be used to estimate the Arrhenius constants. In addition, secondary ion mass spectrometry (SIMS) hydrogen profiling of Napa Glass Mountain obsidian hydrated at 90 °C reveals that the early stages of diffusion exhibit a dynamic behavior that includes a fluctuating hydrogen concentration and a changing diffusion coefficient that slows with time.
