Impact of charring on cereal grain characteristics: linking prehistoric manuring practice to δN signatures in archaeobotanical material

Systematic use of animal manure has been demonstrated to be detectable in the plant δ¹⁵N value but evidence of manure affecting isotopic composition is mainly based on studies of fresh plant material. These findings can potentially be applied to archaeobotanical assemblages and thus provide information about prehistoric manuring practice. Prehistoric grains are generally found in a charred state of which the exact charring conditions are unknown but most likely often multifarious. In this study we examined the influence of grain weight and a range of charring conditions with regards duration, temperature, oxygen availability, and manuring. The charring was applied to emmer, spelt and naked barley with assessment of weight loss, N concentration and δ¹⁵N. There were only small and non-systematic variations in δ¹⁵N in relation to grain weight class. We also found that charring did not distort δ¹⁵N in either a systematic or substantial way and conclude that manuring most likely will be detectable in archaeobotanical charred grains. As certain within-grain variability in δ¹⁵N existed, especially in the intensively manured grains, the resolution of this kind of information should be carefully considered. However, despite attempts to deliberately tamper and distort the grain δ¹⁵N signature, the changes observed in this study were too small to be of any consequences for the archaeobotanical applicability of the method. Thus the isotope method offers unique evidence about prehistoric manuring practice.     

Declaration on Behalf of an Archaeology of Sexe

This article is an attempt to demonstrate the basic weakness of gender as a theoretical concept when studying prehistoric embodiment. ‘Gender ‘is theoretically linked to ‘sex’, known as the ‘sex–gender system’. The study of past genders, in the sense of prehistoric normative roles and symbols, has decreased in interest among archaeologists, in favor of studying sex, i.e., sexual practice and orientation. This switch to sex is part of archaeologists’ endeavors to understand prehistoric bodily subjects. I will here recapitulate on the concept of gender and its serious limitations. I will furthermore try to shed light on how the turn to sex involves an encounter with almost exactly the same fallacies as did the focus on gender. As an alternative for the future, I suggest social identity and embodiment be studied under the theoretical label of ‘sexe’.     

A calf for all seasons? The potential of stable isotope analysis to investigate prehistoric husbandry practices

The Early Bronze Age barrows at Irthlingborough and Gayhurst in central England are notable for the large number of cattle (Bos taurus) remains associated with their human Beaker burials. Previous work using strontium isotope analysis has indicated that most of the cattle analysed, and one aurochs (Bos primigenius), were of local origin [Towers, J., Montgomery, J., Evans, J., Jay, M., Parker Pearson, M., 2010. An investigation of the origins of cattle and aurochs deposited in the Early Bronze Age barrows at Gayhurst and Irthlingborough. Journal of Archaeological Science 37, 508–515.]. In this study, stable isotope analysis of enamel and bone was carried out to investigate whether the mature cattle had experienced similar husbandry practices, climate and environment. Bulk carbon, nitrogen and sulphur isotope analysis of collagen suggested most were consuming similar sources of plant protein from environments probably local to the sites and this was supported by high resolution intra-enamel carbon isotope profiles. Oxygen isotope profiles indicated the aurochs and most of the cattle experienced similar climatic regimes: the only exception being an animal with a non-local strontium isotope ratio. However, a comparison of seasonality profiles of the local animals using estimated tooth formation times showed that there was no consistency in season of birth: the animals appeared to have been born throughout the year. Cattle can breed throughout the year but it requires considerable human effort and intervention to successfully overwinter young stock; it is therefore unlikely to have been carried out without good reason and benefit if winters were harsh. One reason is to ensure a continuous supply of milk. Measuring oxygen isotope profiles to identify year-round calving may thus be a potential indicator of dairying economies.     

Rewriting the founder: Werden on the Ruhr and the uses of hagiography

The rich hagiographical corpus, charters and privileges of the monastery of Werden on the Ruhr allow unparalleled access to its ninth-century history. This article focuses upon three ninth-century vitae of its founding saint which delineate both the transformations which Werden underwent in the course of the century and the ways in which the monastery attempted to respond and adapt to these changes. In so doing, it illuminates the role that saintly relics and hagiography could play in the formation of Christian communities both within and beyond cloister walls.     

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.     

Pastures lost? A dental microwear study of ovicaprine diet and management in Norse Greenland

The management of ovicaprines by the Medieval Norse farmers in Greenland is explored using dental microwear analysis. Adult and juvenile ovicaprines from Norse contexts in Greenland are shown to exhibit microwear patterns very different to those in modern Greenlandic sheep; while modern sheep demonstrate microwear consistent with low levels of soil ingestion under extensive, low stocking-rate grazing regimes, Norse sheep/goat display striated microwear patterns indicative of high levels of soil ingestion and, potentially, overgrazing. This high abrasive grazing signature is present in the inland region of the Western Settlement from 1150 AD onwards, may be evident in the inland Eastern Settlement from an equally early date and is also detected during the later phases of occupation in the Western settlement (14th and 15th centuries AD). It is argued that these results provide further evidence that maladaptive grazing practices led to a decline in the viability of pastoral farming in Greenland, and, moreover, that overgrazing did not merely occur towards the end of the settlement as a consequence of the worsening climate of the ‘Little Ice Age’ but rather was present in both the Western and the Eastern Settlement from a relatively early date.     

WELCOME TO THE NEIGHBORHOOD: HOW CAN REGIONAL SCIENCE CONTRIBUTE TO THE STUDY OF NEIGHBORHOODS?*

ABSTRACT We argue in this paper that neighborhoods are highly relevant for the types of issues at the heart of regional science. First, residential and economic activity takes place in particular locations, and particular neighborhoods. Many attributes of those neighborhood environments matter for this activity, from the physical amenities, to the quality of the public and private services received. Second, those neighborhoods vary in their placement in the larger region and this broader arrangement of neighborhoods is particularly important for location choices, commuting behavior and travel patterns. Third, sorting across these neighborhoods by race and income may well matter for educational and labor market outcomes, important components of a region's overall economic activity. For each of these areas we suggest a series of unanswered questions that would benefit from more attention. Focused on neighborhood characteristics themselves, there are important gaps in our understanding of how neighborhoods change – the causes and the consequences. In terms of the overall pattern of neighborhoods and resulting commuting patterns, this connects directly to current concerns about environmental sustainability and there is much need for research relevant to policy makers. And in terms of segregation and sorting across neighborhoods, work is needed on better spatial measures. In addition, housing market causes and consequences for local economic activity are under researched. We expand on each of these, finishing with some suggestions on how newly available data, with improved spatial identifiers, may enable regional scientists to answer some of these research questions.     

Gendered orphan kits,authority, power and the role of rumor in the woodlands of Mozambique

Recipient communities often distribute humanitarian aid in unexpected ways that reveal critical power dynamics and relationships. This article examines a case involving ‘orphan kits’ distributed by the staff of an international non-governmental organization in Mozambican woodland communities. The kits contained food and school supplies allocated according to a strict gender distribution mandate, which was of secondary importance compared with local obligations tied to enduring matrilineal social relations. Families divided the kits among kin and allocated a portion of the kits to local leaders as tribute. The seemingly simple act of leaders placing orphans on a list can signify the future arrival of much-needed support while also sparking fears of disciplinary powers governing family structures, labor and culturally and politically oppositional lives. Rumors narrate the effects of particular list-making procedures, allowing families to observe, interpret and express ideas about coercive and productive power relations. Rumors took up kit contents such as sardine tins to catalyze debates about proper leadership and comportment of orphans and their families. The article illustrates how feminist geographers can treat rumor and liminal interventions seriously as constitutive of contested power relations rooted in eco-social spaces.
