Calving seasonality at Pool,Orkney during the first millennium AD: an investigation using intra-tooth isotope ratio analysis of cattle molar enamel

The identification of dairying is essential if we are to understand economies of the past, particularly in northwest Europe, where a high degree of lactose tolerance suggests that fresh milk has long been a significant food product. This paper explores a possible link between economic focus and seasonality of calving. Although cattle (Bos taurus) can breed throughout the year, animals living in temperate regions with minimal or no human management tend to breed seasonally, their breeding behaviour being strongly influenced by the availability of food. In order to achieve a year-round supply of fresh milk in the past, it is likely that multiple-season calving was necessary, which would have required additional husbandry effort. Alternatively, for meat-focussed economies or those based on storable dairy products, a strategy of single-season calving in spring may have been favoured to maximise the utilisation of spring and summer vegetation. Cattle birth seasonality is investigated through isotope ratio analysis (δ¹⁸O, δ¹³C) of tooth enamel. Results for cattle from Pool, Orkney dating to the latter part of the first millennium AD suggest that calving occurred during at least three seasons implying that the continuous provision of fresh milk was of economic importance.     

Landscapes of Stone: Contextualizing Greenstone Working and Lithics from Clodgy Moor,West Penwith,Cornwall

Between 2004 and 2011 Graham Hill and Dave Edwards plotted nearly eight thousand prehistoric artefacts from ploughed fields across the Clodgy Moor area of West Penwith. In 2011 a project was carried out by the Historic Environment Service Projects team, Cornwall Council, the Portable Antiquities Scheme and the Cornwall Archaeological Society to catalogue and digitize all the finds recorded from the fieldwalking.

The project demonstrated that some places within the project area were persistent locales which were occupied throughout the Mesolithic and Neolithic periods. The results were particularly significant because they shed light on the context of the production of greenstone axes, widely exchanged around Britain and across the Irish Sea during the Neolithic, and suggest why, despite large numbers of artefacts, no greenstone ‘axe factory’ site has been found close to the potential sources of the greenstone before.     

METHODOLOGICAL AND SPATIO-TEMPORAL CONTEXTS FOR GEOMORPHOLOGICAL KNOWLEDGE: ANALYSIS AND IMPLICATIONS

Scientific statements are valid only within the confines of the approach and scale of study adopted at the outset of the inquiry. Therefore, geomorphological knowledge is considered to be valid only within the methodological and/or spatio-temporal framework adopted for study. New approaches add to understanding by changing the context within which phenomena are viewed but cannot invalidate existing concepts: these can be invalidated only if they are logically or empirically unsupported within their own frame of reference. Research programs may become self-fulfilling because it is only within their own context that hypotheses, with which they might be falsified, are generated and tested: indeed, an approach might not be capable of generating any falsifying hypotheses but be able to produce only hypotheses that are amenable to that particular mode of investigation. Therefore, contributions should be judged only within their own, stated methodological base and alternative approaches should be actively considered. Tout énoncé scientifique n'est valable que dans le cadre de l'approche et de l'éhelle d'analyse adoptés au début de la recherche. les connaissances géomorphologiques ne sont donc considérés valides que dans les limites méthodologiques et ou à I'intérieur des coordonnées espace-temps choisies pour l'étude. De nouvelles approches aident A la compr6hension en modifiant le contexte à l'intbrieur duquel les phénomènes sont examinés, mais elles ne peuvent pas annuler les concepts existants; ces derniers ne peuvent être invalidés que s'ils ne sont pas supportés de façon logique ou empirique dans leurpropre cadre de reférénces. Des programmes de recherche peuvent se réaliser d'eux-mêmes, car c'est dans leur propre contexte que les hypothèses, avec lesquelles ils peuvent être falsifies, sont créées et essayées; de fait, il se peut qu'une approche ne génère aucune hypothèse falsifiante, mais puisse ne produire que des hypotheses conformes au mode particulier d'investigation. les contributions ne doivent donc être jugées qu'à l'intérieur de leur propre base méthodologique, et d'autres approches doivent être considéréss de façon active.     

Archaeological Survey of Dynamic Coastal Landscapes and Paleoshorelines: Locating Early Holocene Sites in the Prince Rupert Harbour Area,British Columbia,Canada

We present and test a predictive archaeological survey model that targets early Holocene paleoshorelines in the Prince Rupert Harbour area using LiDAR bare earth digital terrain models and a 15,000-year reconstructed history of relative sea level change. Despite a century of archaeological research in the study area, no sites dating earlier than 6000 cal b.p. had been identified prior to our research. Our field survey identified three early Holocene sites associated with paleoshorelines 7–10?m above current sea level (masl). These locations demonstrate repeated use through the Holocene even as shoreline position changes. We discuss these new data in relation to the early Holocene archaeological record from the rest of the northern Northwest Coast and suggest that the region was ubiquitously occupied by this time and that the lack of recorded early Holocene sites in some areas is likely a result of survey and preservation bias, rather than historical reality.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.     

Comparison of GIS‐Based Logic Scoring of Preference and Multicriteria Evaluation Methods: Urban Land Use Suitability

Multi‐criteria evaluation (MCE) methods are useful tools to evaluate the land suitability for various uses and assist in the effective management of available land. Many common GIS‐based MCE methods, such as analytical hierarchy process (AHP), ordered weighted averaging (OWA), and a combination of AHP and OWA methods (AHP–OWA) are not able to fully represent all the logic that constitute a wide range of human decision‐making reasoning. Consequently, improved GIS‐based MCE methods such as Logic Scoring of Preference (LSP) method are needed. The main objectives of this study are to: (1) implement the GIS‐based LSP method for land suitability evaluation and (2) compare qualitatively and quantitatively the suitability maps generated by LSP and three GIS‐based MCE methods. This study was implemented with data sets from Boulder County, Colorado, USA for the case study of the urban land suitability evaluation. The qualitative properties of MCE methods and the Receiver Operating Characteristic (ROC) statistics were used as comparison metrics. The results indicate that soft computing methods and particularly LSP performed the best among GIS‐based MCE methods for the urban land use application.     

An investigation of the origins of cattle and aurochs deposited in the Early Bronze Age barrows at Gayhurst and Irthlingborough

The Early Bronze Age round barrows at Irthlingborough, Northamptonshire and Gayhurst, Buckinghamshire contained remarkably large quantities of cattle (Bos taurus) remains. At Irthlingborough, at least 185 skulls with smaller numbers of mandibles, shoulder blades and pelves were found together with a small number of skeletal elements from aurochs (Bos primigenius). In contrast, the remains from Gayhurst are dominated by the limb bones from more than 300 animals. This study employed strontium isotope ratio analysis of cattle tooth enamel from 15 cattle and one aurochs to investigate the diversity of the animals' origins at both sites and provide insights into Early Bronze Age funerary practices. Although strontium results show that most of the cattle and the aurochs included in this study were consistent with local origins, one animal from each barrow was born remotely, most likely in western Britain. In addition, a second Gayhurst animal was consistent with origins in a region of chalk rather than the local Jurassic sediments.
