Norse Animal Husbandry in Liminal Environments: Stable Isotope Evidence from the Scottish North Atlantic Islands

This paper employs ?13C and ?15N analysis of bone collagen to explore animal management at large Norse settlement sites in the liminal environments of the Scottish North Atlantic Islands. The Norse period was a time of social, cultural and economic change; the need to feed an expanding population and the demand for trade meant that domestic stock were a crucial resource. Our results indicate that rearing animals in these challenging insular environments required careful management. At all sites, the diet and movement of domestic cattle and sheep were highly similar and carefully controlled and, despite many of the analysed settlements lying close to the coast, there was no use of shorefront grazing or fodder resources. In contrast, pig rearing strategies varied across the island groups. In the Western Isles pig diets were diverse, indicative of household or ad hoc management, whilst on Orkney all pigs consumed a more restricted diet based primarily on terrestrial protein. A comparison of red deer with domestic stock on the Western Isles indicates that both groups were exploiting similar grazing niches.This research was undertaken by the authors at Cardiff University as part of a PhD project.

Land and sea: understanding diet and economies through time in the North Atlantic Islands

This thesis explores changes in dietary and economic behaviour through time in the North Atlantic Islands of Scotland, from the Mesolithic-Neolithic transition through to the Norse period. Traditional zooarchaeological techniques are used alongside human and faunal stable isotope analysis to explore past diet of humans and animals. The challenges of integrating these two different datasets and methodologies for enhancing interpretations of these lines of evidence are explored. A suite of faunal isotopic values though time were generated to characterise animal diets, past husbandry strategies, to provide a baseline to interpret human values, and to understand temporal and geographical variations in isotopic values. Faunal isotopic values indicate that shore front resources were used by past populations, and highlight temporal and geographical differences in management practices and foddering strategies. Results demonstrated that marine species were not a major aspect of diet in the Neolithic, supporting Schulting and Richards (2002a). In the Bronze Age there is an increase in the quantity of fish bones present within the faunal assemblages in the Western Isles, however they were not being consumed in sufficient quantities to affect the human bone collagen isotopic values. During the Iron Age there is a further increase in the quantity of fish bones present in assemblages in the Western Isles, and evidence of fish consumption in human and pigs. In contrast evidence of marine food consumption in Iron Age Orkney is minimal, indicating divergent dietary and economic practices in place between these regions. During the Norse period fish bones account for high proportions of the zooarchaeological assemblages in both Orkney and the Western Isles, with different species being exploited. Finally comparisons are drawn with island and inland sites in Britain and Europe, exploring how far these dietary and economic practices observed are influenced by localised environmental conditions, and wider social factors

Excavations at cathole cave, Gower, Swansea

The discovery of an engraving in Cathole Cave in 2010 led to a decision to grille the cave. In 2012 excavations took place in the cave ahead of the grilling. Two areas of the cave were excavated; Trench A demonstrating that the cave held a faunal occupation dating to MIS 3, at a time, or times, between 50,000 and 30,000 BP. Two flint blades of Upper Palaeolithic appearance were discovered along with a faunal assemblage from within the shallow deposits across the line of the grille. The work demonstrated that the earlier excavations in the cave by Col. E.R. Wood were extensive and at this point in the cave he excavated to bedrock. The standing section (Trench B) which he left exposed further along the main cave passage was also cleaned, recorded and sampled. The deposits contain a faunal assemblage dominated by microfauna, but no cultural artefacts were found. The dating of key animal bones, the analysis of the microfauna and the sedimentological analysis have together enabled a picture to be developed of the changes in this section from the mid-Devensian to Late Glacial and Holocene

Adaptability, resilience and environmental buffering in European Refugia during the Late Pleistocene: Insights from La Riera Cave (Asturias, Cantabria, Spain

Abstract: The Upper Palaeolithic in Europe was a time of extensive climatic changes that impacted on the survival and distribution of human populations. During the Late Glacial Maximum (LGM), southern European peninsulas were refugia for flora, fauna, and human groups. One of these refugia, the Cantabrian región (northern Atlantic Spain), was intensively occupied throughout the Upper Palaeolithic. Characterising how climatic events were expressed in local environments is crucial to understand human and animal survival. La Riera Cave (Asturias) has a rich geo-cultural sequence dating between 20.5kyr BP to 6.5kyr BP and represents an ideal location in which to explore this. Stable isotope analysis of red deer and ibex is used alongside other environmental and climatic proxies to reconstruct Late Upper Palaeolithic conditions. Results show that during the LGM, ibex adapted their niche to survive, and became a major prey species for humans. The diverse environmental opportunities offered in the high-relief and coastal environs of La Riera may help to explain the high human population levels in the Cantabrian Region throughout the Late Upper Palaeolithic. Despite fluctuating conditions, herbivores and humans had the flexibility and resilience to adapt, demonstrating the importance of southern European refugia for the survival of different species.This research was funded by a Marie Skłodowska-Curie Individual Fellowship grant awarded to JRJ (H2020- MSCA-IF-2014-656122).

'The Mould that Changed the World':Quantitative and qualitative evaluation of children's knowledge and motivation for behavioural change following participation in an antimicrobial resistance musical

BackgroundA primary school musical ("The Mould that Changed the World") was developed as a unique public engagement strategy to combat antimicrobial resistance (AMR) by engaging children in the story of the discovery of antibiotics, the risks of drug-resistant infections and the importance of prudent antibiotic use.MethodsThe musical intervention was implemented in two UK primary schools by music specialists through a series of workshops, associated learning resources and performances to relatives. Participating children (n = 182), aged 9 to 11 years, were given an online questionnaire in the classroom before rehearsals began and at two weeks post-performance with a six-month evaluation in one school. The impact of the musical was analysed using generalised linear models to control for confounding factors. For the qualitative evaluation, fifteen participating children were selected randomly from each school to take part in semi-structured focus groups (n = 5 per group) before rehearsals began and two weeks post-performance.FindingsKnowledge gain was demonstrated with children being more likely to answer questions on key messages of the musical correctly at two weeks post- performance (response rate 88%, n = 161) compared with the pre-rehearsal questionnaire (response rate 99%, n = 180) (bacteria can become resistant to antibiotics OR 4.63, C.I. 2.46-9.31 pInterpretationThis study demonstrates that musical theatre can improve both short and long-term knowledge. It demonstrates a hitherto infrequently reported change in attitude and motivation to change behaviour in children at an influential age for health beliefs. This unique public health tool has the potential for high impact particularly if rolled out within national education programmes for primary school aged children

Reassessing palaeoenvironmental conditions during the Middle to Upper Palaeolithic transition in the Cantabrian region (Southwestern Europe)

Climatic and environmental changes have been commonly proposed as driving factors behind the decline of Neanderthals in Europe. The Cantabrian region, in northern Iberia, is a key area for understanding the replacement of Neanderthals by Anatomically Modern Humans, where an early disappearance of Neanderthals in relation to other areas of Iberia has been proposed. To evaluate how climate might have influenced human behaviour during Marine Isotope Stage 3, an accurate review of palaeoecological conditions is required. For the first time, an assessment of the regional available terrestrial proxies linked to archaeo-palaeontological sites, including small vertebrate assemblages, pollen sequences, charcoal data and stable isotope studies on macromammals is undertaken in this region. In addition, records from macrofaunal assemblages and glacial records have also been considered. To standardise the information and allow inter-site comparison, data from pollen and small vertebrate sequences were transformed into quantitative climatic estimations of temperature and precipitation. Results show highly variable climatic shifts between archaeological levels, being consistent with the climatic fluctuations observed in the marine and ice core records. Small mammal assemblages reveal a mosaic landscape of open meadows followed by scattered forested areas. A progressive trend towards aridity from the end of the Mousterian to the early Aurignacian is reflected by changes in arboreal pollen, macromammal species and stable isotopes evidence on ungulates consumed by late Neanderthals and Anatomically Modern Humans in the region. This review suggests a decrease in temperatures and rainfall from 48,000 to 44,000 cal BP (after Heinrich Event 5) which coincides with the late Neanderthals in the region and followed by a populational hiatus until 43,000 cal BP. Despite the multiple intra-site environmental proxies available, this study challenges the fragmentary regional record during this key period for human evolution and reveals that further research is needed to obtain a complete regional highresolution palaeoenvironmental and palaeoclimatic reconstruction.This research is funded by the European Research Council, under the European Union's Horizon 2020 Research and Innovation Programme (grant agreement No. 818299-SUBSILIENCE ERC CoG project https://www.subsilience.eu), the Spanish Ministry of Science and Innovation (NEWINDS; PID2021-125818NB-I00) and the Cantabrian Government (Proyecto Puente 2021)
