Molecular and morphological analyses of avian eggshell excavated from a late thirteenth century earth oven

Using ancient DNA (aDNA) extracted from eggshell of the extinct moa (Aves: Dinornithiformes) we determined the species composition and number of eggs found in a late thirteenth century earth oven feature at Wairau Bar (South Island, New Zealand) – one of New Zealand’s most significant archaeological sites. Mitochondrial and nuclear DNA signatures confirmed this oven feature contained fragments of at least 31 moa eggs, representing three moa genera: Emeus; Euryapteryx; Dinornis. We demonstrate through the genetic identification of 127 moa eggshell fragments that thickness is an unreliable character for species assignment. We also present a protocol for assessing the preservation likelihood of DNA in burnt eggshell. This is useful because eggshell fragments found in archaeological contexts have often been thermally modified, and heat significantly increases DNA fragmentation. Eggshell is widely used in radiocarbon dating and stable isotope research, this study showcases how aDNA can also add to our knowledge of eggshell in both archaeological and palaeoecological contexts.     

Estimating original flake mass from 3D scans of platform area

This study confirms the increased capacity to predict flake mass that arises from more accurately measuring surface area in three dimensions using a digital scanner. We also reveal the existence of significantly different relationships between platform area and flake mass for flakes with different platform types and ventral and dorsal morphologies. These different relationships between platform surface area and mass have not been previously identified, and reveal the complexity of platform/mass relationships. Using multivariate regression of 3D platform surface area and external platform angle we improve the accuracy of predictions of original flake mass. We propose a method for studying reduction intensity on retouched flakes, based on comparing predictions of the initial mass of the flake with measurements of the mass following retouching to estimate the amount of mass removed through retouching. We name this approach the Initial-/Terminal-Mass Comparison, or ITMC. Our experiments demonstrate that the capacity of the 3D platform scans to predict flake mass, and by implication the capacity of the ITMC to estimate mass loss, rivals or exceeds the capacity demonstrated for existing reduction measures.     

The Violence of Poverty: Theology and Activism in an “Age of Austerity”

ABSTRACT

Faith groups are in the front line of the struggle to defeat poverty in breadline Britain. Given their roots in local communities Churches and Christian NGOs are well-placed to challenge economic policies that have resulted in the spiraling of food poverty, homelessness, personal debt and child poverty. By framing poverty as a political choice, a form of structural violence and systemic sin this paper brings peace studies and political theology into a constructive dialogue. In the face of ongoing “austerity” the paper demonstrates that poverty represents a clear and present danger to the social fabric of the UK and argues that only a re-imagined interdisciplinary theology of liberation can provide academics and activists with the tools needed to defeat systemic poverty and the cultural violence upon which it rests.

Peatland conservation in Buchan,north‐east Scotland: The historic context and contemporary issues

Scottish peatlands are now recognised as important habitats for conservation, and are increasingly protected by both national and international designations. This paper examines peatland conservation in north‐east Scotland, using recently published data to assess habitat quality, and relating this to longer‐term historical trends in attitudes towards peatlands, and their utilisation. The historical data indicates that peatland losses in northeast Scotland have been extensive, and occurred rapidly during the 18th and 19th centuries, when peatlands were regarded as fuel sources, or wastelands which could be converted to agricultural use. Threats have lessened in the second half of the 20th century, and many sites are now protected by conservation designations. However, historical attitudes towards peatlands often persist, and this can pose problems which must be addressed if conservation management is to be successful.     

Why Scotland needs more than just a new migration policy

The Scottish Executive has adopted a policy to combat Scotland's declining population by encouraging inward migration. Using a multi‐state population model this paper presents nine long‐term population scenarios for Scotland using three net international migration levels and three fertility paths. The results show inward migration can slow population decline but makes little difference to population ageing. Without a higher fertility rate Scotland's population will become demographically unsustainable. Our simulations show that a higher fertility rate substantially reduces the future ageing.     

The last glaciation in the Western Mourne Mountains,Northern Ireland

During the late‐Midlandian (25–13 ¹⁴C ka BP), the last Irish Ice Sheet was thicker in the Western Mourne Mountains than previously argued. Geomorphological and sedimento‐logical analysis shows that regional ice from the Irish Ice Sheet spilled over the mountains, reaching a major limit 5 km along Pigeon Rock Valley. These findings differ from the previous view that a local valley glacier occupied the valley during this period. The pattern of deglaciation was reconstructed using glacial and periglacial evidence. A complex topographic environment in the upper reaches of the valley suggests that regional ice stagnated as it wasted away. During the Nahanagan Stadial (Younger Dryas, ca. 11–10 ka ¹⁴C BP) an arcuate ridge was formed on the western flank of the valley. Calculations suggest that the Equilibrium Line Altitude, influenced by topographic conditions favourable for snow accumulation, was approximately between 1736 m and 1386 m lower during the Nahanagan Stadial than at present.
