Yes / A key goal for archaeozoology is to define and characterise pastoral farming strategies. In the last decade, some of the most innovative approaches for addressing these questions have centered on the mammalian dentition, including inter alia sequential sampling of stable isotopes, dental microwear analysis and the study of dental pathologies. It is when these techniques are integrated and combined with more traditional approaches, such as tooth eruption and wear, however, that their full potential is realised. In this article we demonstrate how such an integrated dental analysis combining isotopes, microwear, dental development, dental pathologies, tooth eruption and wear can be used to elucidate changing pastoral practices and their impacts on the landscape from the Iron Age and Viking-Late Norse periods in the North Atlantic islands, a period of significant socio-economic and cultural change in this region. Analysis focuses on two case study sites, Mine Howe, dating to the Atlantic Middle Iron Age (MIA) and the Earls’ Bu, one of the residences of the Orkney Earl’s from the 10th to 13/14th centuries AD. Each of the techniques applied to the sheep/goat and cattle dentition identifies clear differences between the two sites, in diet, in culling season, herd health and stress levels, all of which point to potential differences in underlying husbandry practices. These are related to wider socio-economic developments in Orkney at these periods, specifically increasing control of pastoral resources and economic production by North Atlantic elites in the MIA and the emergence of manorial estates in Late Norse/Early Medieval Scandinavia. / AHRC PhD studentships; British Academy Mid-Career Fellowship (2014-5)

This thesis investigates the prehistoric diet of humans and two of their key commensals on Aitutaki using stable carbon and nitrogen isotopes. This technique gives us new insight into the diet of these three groups and results are considered in the context of the development of agricultural systems on Aitutaki, as well as in light of the wider context of cultural developments and environmental change in the Cook Islands and Polynesia as a whole. Ultimately, it allows us to more fully understand the complex interactions between humans and the two largest commensals in order to evaluate the utility of these animals as proxies for humans in dietary analyses. The results indicate that the prehistoric human diet on Aitutaki can be characterised as mixed, dominated by terrestrial plants and marine protein with lesser amounts of terrestrial protein. While the amount of protein eaten by the individuals was very similar, they varied in how much marine or terrestrial protein they ate. The pigs had a slightly more terrestrial diet, with a greater emphasis on plant foods. Their protein intake was more variable and terrestrial in nature than the humans’. Dogs had a higher trophic level, more marine-oriented, diet than either humans or pigs. Like the humans, their diet contained more variation in the source of their protein. Overall, however, the diets of all three groups were very similar. While the overall nature of the human, pig and dog diets, and their relationships to one another, remained relatively constant over time, beginning in the 14th century they show a decline in the amount of fish consumed and had a more terrestrial diet overall. This confirms trends seen in the archaeofaunal assemblages, and throws light on the relationship between environmental change and human subsistence practices in East Polynesia. The similarity of the pig and dog diets to human diet, and the fact that the relationship remained constant over time, demonstrates the usefulness of the Aitutaki commensal animals as proxies for humans in stable isotope analysis. However, the specifics of that relationship vary by species and by place. While the individual dietary variability provides us with new ways of looking at dietary change within populations, it also demonstrates the importance of obtaining as large an assemblage for analysis as possible in order to ensure that samples are representative of the population as a whole.

Historical evidence from contemporary documents established that Irish migrants to London during the Great Irish Famine (1845-1852) were likely to come from low socio-economic groups in south-west Ireland, and has characterised mid-19th-century health status and living conditions in both locations. Using samples from 119 individuals from the Catholic cemetery at Lukin Street, London (1843-1854) and 20 from the Union Workhouse Famine cemetery, Kilkenny, Ireland (1847-51), mean bone collagen isotope values were established for the well-documented Irish pre-Famine potato-based diet (¿15N 10.6¿, ¿13C -19.1¿), and the diet of contemporaneous Londoners (¿15N 12.6¿, ¿13C -19.1¿). The introduction of maize as a short-term Famine relief food was identified in three Kilkenny juveniles with bone collagen ¿13C above -17¿, and incremental dentine collagen demonstrating temporal changes in ¿13C consistent with dietary change from C3 to C4 plants. Bone collagen values for two Lukin Street individuals were consistent with high marine protein consumption. Techniques developed in this study to sample increments of dentine representing nine months or less of life have improved temporal resolution not only for migration events but also short-term dietary changes and physiological status during childhood. Combining epigraphic, osteological and archaeological evidence, individual ¿lifeways¿ have been constructed using isotope data and provide insights into the connection between health, diet and skeletal manifestations of deprivation during childhood and adolescence. New models are investigated for examining maternal and infant health using dentine collagen increments formed in utero and combining dentine and bone collagen values to explore the effects of nutritional stress on bone turnover. / Arts and Humanities Council.

This thesis reports an investigation of Iron Age diet in Britain using carbon and nitrogen stable isotope data obtained from skeletal material from four locations across England and southern Scotland. Both human and animal bone Collagen has been analysed from Wetwang in East Yorkshire and other sites in East Lothian, Hampshire and Cornwall. Animal bone from Dorset has also been included. The aims of the study were to characterize British Iron Age diet in general isotopic terms and also to provide a contextual base for future analysis which allows an understanding of both inter- and intra-site variation in such data for this and other periods. The comparisons across the locations allowed consideration of geographical variability within England and southern Scotland and included material from coastal sites (Cornwall and East Lothian), from sites with easy access to rivers and estuaries (Hampshire) and an inland site where access to water would have been more difficult (Wetwang). All human groups were consuming high levels of animal protein and there was very little evidence for the consumption of aquatic resources. There was significant variation in 815N values between the locations, which was reflected both in the humans and the herbivores, such that it is likely to be related to environmental rather than to dietary differences. Intra-site group comparisons at Wetwang showed very little variation within the cemetery population IM according to age, sex, subjective status category or site phase. The data were very consistent within the populations, although those for Hampshire displayed more variation in nitrogen.

Isotope analyses on human and faunal skeletal remains from different Swedish Neolithic archaeological contexts are here applied as a means to reconstruct dietary strategies and mobility patterns. The chronological emphasis is on the Middle Neolithic period, and radiocarbon dating constitutes another central focus. The results reveal a food cultural diversity throughout the period in question, where dietary differences in part correspond to, but also transcend, the traditionally defined archaeological cultures in the Swedish Early to Middle Neolithic. Further, these differences, and the apparent continued utilisation of marine resources in several regions and cultural contexts, can only in part be explained by chronology or availability of resources depending on geographic location. Thus, the sometimes suggested sharp economic shift towards an agricultural way of life at the onset of the Neolithic is refuted. Taking the potential of isotope analyses a step further, aspects of Neolithic social relations and identities are discussed, partly from a food cultural perspective embarking from the obtained results. Relations between people and places, as well as to the past, are discussed. The apparent tenacity in the dietary strategies observed is understood in terms of their rootedness in the practices and social memory of the Neolithic societies in question. Food cultural practices are further argued to have given rise to different notions of identity, some of which can be related to the different archaeological cultures, although these cultures are not to be perceived as bounded entities or the sole basis of self-conceptualisation. Some of these identities have been focused around the dietary strategies of everyday life, whereas others emanate from practices, e.g. of ritualised character, whose dietary importance has been more marginal. Isotope analyses, when combined with other archaeological indices, have the potential to elucidate both these food cultural aspects. / At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Submitted.
