This paper examines the exploitation of marine molluscs in the Western Isles of Scotland, from the Bronze Age to Norse periods (2500 BCE–1266 CE). Through analysis of shell assemblages from thirteen archaeological sites, we investigate changing shellfish exploitation practices across time and space. We consider whether these variations reflect cultural preferences, local availability and environments, or evidence of unsustainable harvesting practices. The research examines not only dietary contributions but also explores potential non-food uses of shells, as well as providing insights into coastal environment exploitation. While limpets (Patella spp.) remained consistently important throughout much of prehistory, there was a notable shift toward periwinkles (Littorina littorea), beginning in the Late Iron Age and continuing into the Norse period. This transition appears to reflect a combination of cultural preferences and local ecological availability rather than simple resource depletion. The study highlights the value of standardised methodological approaches to shell analysis and the importance of considering individual and community agency in the interpretation of zooarchaeological assemblages.

In this paper, we revisit the Mesolithic–Neolithic transition in western Scotland and the links between early European farmers and middens in light of new aDNA, radiocarbon, and stable isotopic evidence. New carbon and nitrogen stable isotopic data for food sources (plant and animal remains) from a Mesolithic site are presented, and dietary FRUITS models are recalculated based on these data. We also respond to recent criticisms of the Bayesian approach to diet reconstruction. Results support the view that Neolithic people had at most a minimal contribution of marine foods in their diet and also point to a dual population model of transition in western Scotland. A significant aspect of the transition in coastal western Scotland is the co-occurrence of Neolithic human remains with shell-midden deposits, which appears to contradict stable isotopic evidence indicating a minimal contribution of marine resources to the diet of early farming communities in the region. Finally, we highlight the need for further research to fully address these issues, including (1) targeted isotopic analyses of potential plant and animal resources, (2) single-entity radiocarbon and ZooMS analyses of animal bones and artefacts from shell middens, and (3) further aDNA analyses of the remains of Late Mesolithic and Neolithic people.

Heart and skeletal muscle inflammation (HSMI) is a significant disease affecting Atlantic salmon (Salmo salar) production in Norway but has had limited impact to production in North America. The causative agent of HSMI is piscine orthoreovirus genotype 1 (PRV-1), and disease variation between regions is suggested to be at least partially driven by genetic variation of the virus. Using controlled laboratory injection challenges, we corroborate variations in disease outcomes for three PRV-1 isolates (PRV-1a from the eastern Pacific, PRV-1a from the western Atlantic, and PRV-1b from the Norwegian sea); however, virus replication dynamics, host recognition, and PRV-1-associated heart inflammation were also discrete relative to the Atlantic salmon stock challenged, irrespective of the viral isolate used. Specifically, New Brunswick Tobique River Atlantic salmon had less (p < 0.01) heart inflammation relative to Mowi-McConnell Atlantic salmon of Western Canada which, in turn, had less (p < 0.01) heart inflammation than Mowi Atlantic salmon of Scotland when cumulatively considering challenges using all three PRV-1 isolates. These data indicate that the presence of PRV-1a or PRV-1b alone is not sufficient to reliably predict disease and highlights at least one potential mechanism (host genotype) for reducing HSMI disease severity.

Recent research conducted by Heritage Crafts, a prominent national advocacy organisation dedicated to preserving traditional heritage crafts in the UK, has unveiled a concerning trend: several traditional craft skills teeter on the edge of extinction within the UK. This revelation stems from the Heritage Crafts Red List of Endangered Crafts, an initiative which identifies crafts facing the risk of endangerment. In their recent 2023 publication, Heritage Crafts highlighted the distressing decline of cut and engraved glass craftsmanship in the UK, categorising and placing both brilliant cutting (as endangered) and copper wheel engraving (as critically endangered) on the Red List of Endangered Crafts in the UK. This means that these crafts pose the risk of not being actively practised. In December 2023, the alarming downturn of these crafts in the UK was explored and discussed during a conference held at Edinburgh College of Art (ECA), entitled Edo-Kiriko: The Art of Japanese Cut Crystal. This event explored the cross-cultural connection and exchange that exists between Scotland and Japan, drawing upon a rich historical exchange that saw the transmission of Western-style glassmaking from Scotland to Japan in the 1870s–1880s. It also details the more recent exchange that has been in place between Edinburgh College of Art (ECA) and the Horiguchi Kiriko glass studio in Tokyo, Japan. This modern-day exchange has seen the recent transmission of glass-cutting skills through a masterclass led by Toru Horiguchi at ECA. This paper presents this conference, introducing the invited speakers and creating a commentary on the proceedings and the plenary discussions that unfolded. Focus and discussion will be given to the factors that have contributed to the current decline of cut and engraved glassmaking in the UK and the possible measures that could be taken to support and safeguard this field. The final part of this paper will offer a reflection on the conference proceedings and will conclude by making an urgent call for the future of cut and engraved glass craftsmanship in the UK. It is hoped this paper will draw attention to the urgent need for support from education and funding bodies, to safeguard and protect these vital heritage crafts, which boast a rich history in the UK.

Phytoplankton guilds are commonly characterised by dominance effects, while the main contribution to biological diversity is given by rare species. Here, we analysed the influence of rare species on taxonomic and functional diversity, which is described by taxa richness and composition, cell size, and size–abundance relationships in phytoplankton guilds. We explore these relationships at global and regional scales by analysing phytoplankton guilds from five biogeographical regions: the Northern Atlantic Ocean (Scotland), the South-Western Atlantic Ocean (Brazil), the South-Western Pacific Ocean (Australia), the Indo-Pacific Ocean (Maldives), and the Mediterranean Sea (Greece and Turkey). We have comparatively analysed the phytoplankton taxonomic diversity of the whole dataset and with the datasets obtained by progressively subtracting taxa occurring in the last 1%, 5%, 10%, and 25% of both numerical abundance and overall biomass. Globally, 306 taxa were identified across five ecoregions with only 27 taxa accounting for 75% of overall numerical abundance and biomass; almost 50% of taxa were lost on every step. The removal of 1% of most rare taxa significantly affected the phytoplankton size–abundance relationships and body-size structure, strongly impacting on small taxa. The progressive removal of additional rare taxa did not further affect phytoplankton size–abundance relationships and size structure. Full article

Rural areas face profound challenges in transitioning towards sustainability. Intensive agriculture is deeply implicated in high greenhouse gas emissions, biodiversity decline and water pollution. As a more socio-economically heterogenous rural Europe emerges with a greater non-farming component, changes such as in-migration and tourism in some areas can also be seen to compromise sustainability, as can an ageing and declining population in others. The dominant means of European rural policy support has been direct income payments to farmers, with modest but increasing expectations of environmental cross-compliance over time. Since the early 1990s, new policy means have been introduced, many based around collaborative actions to enhance sustainability. These include the European Union (EU) Leader scheme, environmental cooperatives, catchment management projects and support for community renewable energy. These changes mark a shift from sectoral support to a more territorial and place-based policy, often built around collaborative partnership models. Scotland has developed a wide and distinctive range of communitarian policies to support sustainable rural development which connect to this territorial approach. This paper reviews the contribution of communitarian and collaborative policies to sustainability transitions, drawing primarily on Scottish policy but referencing these policies against policies in other developed economies.

Complex microstructures of zircon recrystallisation have been discovered in igneous and metamorphic zircons from the Jack Hills Metasedimentary Belt in Western Australia, and the granitic injection complex of Harris in north-west Scotland. Cathodoluminescence (CL), electron backscatter diffraction (EBSD) and wavelength dispersive spectroscopy (WDS) analysis reveal that recrystallisation in the studied zircons is often characterised by (1) translation, bending and fading of the oscillatory zoning; (2) structural recovery of the zircon; (3) an enrichment in Hf and depletion in Y in recrystallised zircon; and (4) the formation of a recrystallisation interface with a minor (<2°) misorientation. A new, composite recrystallisation model in which trace element and dislocation migration occurs shortly after crystallisation during magmatic cooling and pipe diffusion along dislocation arrays formed by the accumulation of dislocations allows enhanced diffusion to enrich Hf and leach U, Pb and Y. After the recrystallisation event, subsequent metamictization of primary zircon (typically with oscillatory zoning) creates zones that can structurally recover through a diffusion-reaction re-equilibration mechanism, resulting in further trace-element mobility. These mechanisms can create complex microstructures in zircons, suggesting that a detailed understanding of the crystallisation and recrystallisation history of a zircon may be required to accurately interpret its U-Pb ages.

Although marine resources are known to have been exploited by both foragers and early farmers in Scotland, the importance of seafood to the diets of Neolithic groups has been widely debated. Here we present paired stable isotope (δ¹³C and δ¹⁵N) and radiocarbon measurements on Early Neolithic human remains from Raschoille Cave in Oban. These are compared with published data for other sites in western Scotland and used to re-evaluate the use of marine resources by the first farmers. The diets of Late Mesolithic foragers and Early Neolithic farmers were modelled from stable isotope data using both Linear and Bayesian (FRUITS) mixing models. Our FRUITS dietary models indicate that Mesolithic foragers obtained much of their dietary protein and calories from marine resources, consistent with the predominance of shellfish, fish and sea mammal remains in their shell middens. Of note is the large proportion of dietary calories obtained from plant foods, which is like that of the early farming groups. The diets of Early Neolithic farmers appear relatively homogeneous across Scotland. Plant foods were the primary source of calories. Meat and/or dairy from terrestrial mammals were the most important source of dietary protein. Marine resources were, at most, a minor component of the ‘lifetime’ diet. Full article

Despite constituting the western-most edge of the population distributions for several native European plants, Ireland has largely been left out of key Europe-wide phylogeographic studies. This is true for birch (Betula pubescens Ehrh. and Betula pendula Roth), for which the genetic diversity has yet to be mapped for Ireland. Here we used eight cpDNA markers (two Restriction Fragment Length Polymorphism (RFLP) and six Simple Sequence Repeat (SSR)) to map the genetic diversity of B. pubescens, B. pendula, and putative hybrid individuals sampled from 19 populations spread cross most of the island of Ireland. Within Ireland, 11 distinct haplotypes were detected, the most common of which (H1) was also detected in England, Scotland, France, and Norway. A moderate level of population structuring (G_ST = 0.282) was found across Ireland and the genetic diversity of its northern populations was twice that of its southern populations. This indicates that, unlike other native Irish trees, such as oak and alder, post-glacial recolonization by birch did not begin in the south (i.e., from Iberia). Rather, and in agreement with palynological data, birch most likely migrated in from eastern populations in Britain. Finally, we highlight Irish populations with comparatively unique genetic structure which may be included as part of European genetic conservation networks. Full article

(1) Background: Scotland has one of the highest rates of obesity in the Western World, it is well established that poor weight profiles, and particularly abdominal obesity, is strongly associated with Type II diabetes and cardiovascular diseases. Whether these associations are apparent in ethnic population groups in Scotland is unclear. The purpose of this study was to examine the associations between different measures of fatness with clustered cardio metabolic risk factors between Scottish South Asian adolescents and Scottish Caucasian adolescents; (2) Methods: A sample of 208 Caucasian adolescents and 52 South Asian adolescents participated in this study. Stature, waist circumference, body mass index, blood pressure, physical activity, and cardiovascular disease (CVD) risk were measured; (3) Results: Significant, partial correlations in the South Asian cohort between body mass index (BMI) and individual risk factors were generally moderate. However, correlations between Waist circumference (WC) and individual risk factors were significant and strong. In the Caucasian cohort, a significant yet weak correlation between WC and total cholesterol (TG) was noted although no other associations were evident for either WC or BMI. Multiple regression analysis revealed that both BMI and WC were positively associated with CCR (p < 0.01) in the South Asian group and with the additional adjustment of either WC or BMI, the independent associations with clustered cardio-metabolic risk (CCR) remained significant (p < 0.005); (4) Conclusions: No positive relationships were found between BMI, WC, and CCR in the Caucasian group. Strong and significant associations between measures of fatness and metabolic risk were evident in Scottish South Asian adolescents. Full article

Expansion of marine aquaculture into more remote areas will likely accelerate over the next decade. Integrating Marine Renewable Energy (MRE) generation technologies (e.g., wind turbines) into remote, off-grid aquaculture sites will reduce reliance on fossil fuels by allowing localised low-carbon power generation, but may also result in novel environmental pressures. In this study, we undertook a thought experiment to assess the potential for increased collision risks to local marine and coastal bird species of integrating small wind turbines (4 units; combined capacity of 200 MWh) into a generalised marine fish farm in western Scotland (UK). Potential risks to bird species were assessed using a bespoke Sensitivity Index (SI) based on 12 factors, including population size, adult survival rate, UK conservation status, flight manoeuvrability, nocturnal flight activity, habitat preference, sensitivity to wind farms, attraction to fish farms for feeding and/or resting, and attraction to other marine anthropogenic structures/activities. SI scores varied substantially between species, but large gulls (Larus sp.) and European shag (Phalacrocorax aristotelis) were expected to be at the greatest potential risk. The general lack of information on interactions between birds and fish farms represented a significant knowledge gap, and greater focus on these interactions is needed to improve future risk assessments.

The northern and western isles of Scotland have proved fertile ground for archaeological investigation over the last 100 years. However, the nature of the landscape with its rugged coastlines and irregular topography, together with rapid peat growth rates, make for challenging surveying. Commonly, an archaeological monument or series of monuments is identified but little is known about the surrounding areas and, in particular, the palaeo-landscapes within which the monuments are located. This situation is exemplified by the standing stones of Calanais in Lewis. Here, surrounding peat bogs have buried a significant portion of the landscape around which the stones were first erected. This project identifies remote sensing geophysical techniques that are effective in mapping the buried (lost) landscape and thus aid better contextualisation of the stone monuments within it. Further, the project demonstrates the most appropriate techniques for prospecting across these buried landscapes for as yet unidentified stone features associated with the lives of the people who constructed the monuments.

This paper examines the use of mapping methodologies in some recent examples of contemporary art that chart the layered seascapes of the remote coastlines on North West Scotland as seen through the lens of visual culture in the Anthropocene. The art projects interrogate conflicting perspectives on landscape and nature in the North. The case studies demonstrate, both directly and indirectly, the political and cultural tensions made evident by the mapping of the micro and macro undercurrents at work in the region, and examine how mapping has been used as a methodology to visualise those intractable material relationships, often using the map as a trope to do so. These mappings make visible the enmeshments of these remote locations into a global ecosystem. The concept of the Anthropocene provides a useful framework to describe the contemporary context of climate change, ecological decline, biodiversity loss and recent discourses on land use within which the artworks by two artists, Julia Barton and Stephen Hurrel, will be discussed. The significance of Kester’s concept of Littoral Art were explored through the eponymous art project by Barton, which maps the human debris brought by the northern sea currents to the shores of the Western and Northern coasts, and Stephen Hurrel’s cultural mapping of the island of Barra on the West Coast. These projects were further considered in the context of Timothy Morton and Tim Ingold’s meshwork theory and the concept of the 19th century Scottish town planner and environmentalist Patrick Geddes, whose urging to ‘think global, act local’ is implicit in the multi-layered understanding of the Anthropocene.

Contrary to hegemonic Western representations of Muslim women as victims of Islam and Muslim men, Sudanese-Scottish Leila Aboulela’s The Translator depicts a Muslim woman, Sammar, whose sense of home and belonging is predicated on her romantic love for her late cousin and husband, Tarig. Therefore, after his death, she feels alienated from her home in Sudan and leaves for Aberdeen, Scotland, where she is ostracized because she is Muslim. While this Muslim identity proves indispensable for her survival and gradual healing, ultimate normalcy and belonging are restored when she reclaims the world of love and acceptance she has lost with Tarig’s death through a new relationship. The romantic love and the language she uses in this relationship allow Sammar to restore the sense of being and the belonging she had at home within the spaces she occupies in Aberdeen, ending her alienation and reclaiming her subjectivity. Using feminist theory and postcolonial theories of place and identity, as well as Lila Abu-Lughod’s notion of emotional discourse as a pragmatic act, this study investigates the novel’s depiction of place and identity as constructed entities embedded in emotion. This depiction, this study proposes, undermine various positionalities and binaries, such as self/other and east/west, allowing Aboulela to approach them more critically. Full article

Interactions between environmental and social change are complex and require deep insights into human perceptions, values, motivations and choices. Humanities disciplines can bring these insights to the study of marine social–ecological systems in the context of global environmental challenges. Such systems can be defined on a range of scales, but the cases most easily studied include those of small islands and their communities. This paper presents findings from three studies in the Western and Northern isles of Scotland, concentrating on some of the processes involved in social sustainability that contribute on the one hand to protecting what a community has, and on the other hand allowing a community to evolve so as to adapt to new conditions. It relates the several sorts of transformations involved, to the role and impact of external institutions such as those of governance of the natural environment, the energy market, and academic research, which together make up the environment of the transformation. By examining the world-views of different groups of actors, this paper illustrates that an understanding of the mental constructs underlying these world-views can help marine governance through integrating different ways of knowing. This paper identifies where it would be useful to employ a transdisciplinary ‘translator’ or a ‘space’ for dialogue in order to capture the diverse ‘visions’ and perceptions that these groups have in relation to management of the marine environment, where there are synergies and where more should to be done to negotiate between competing values and needs. It illustrates the practical contributions to operational policy that can emerge through challenging the dominant management discourses for the marine environment. Full article
