DNA from pollen: principles and potential

This paper describes our recent extraction of ancient DNA (aDNA) from Holocene pollen and discusses the potential of the technique for elucidating timescales of evolutionary change. We show that plastid DNA is recoverable and usable from pollen grains of Scots pine Pinus sylvestris from 10 ka and 100 years ago. Comparison of the ancient sequences with modern sequences, obtained from an extant population, establish a first genetic link between modern and fossil samples of Scots pine, providing a genetic continuity through time. One common haplotype is present in each of the three periods investigated, suggesting that it persisted near the lake throughout the postglacial. The retrieval of aDNA from pollen has major implications for palaeoecology by allowing (i) investigation of population level dynamics in time and space, and (ii) tracing ancestry of populations and developing phylogenetic trees that include extinct as well as extant taxa. The method should work over the last glacial oscillation, thus giving access to ancestry of populations over a crucial period of time for the understanding of the relationship between speciation and climate change.

Dendrochronological evidence for a lower water-table on peatland around 3200-3000 BC from subfossil pine in northern Scotland

Tree-ring analysis of subfossil Pinus sylvestris L., from nine new peatland sites located beyond the species’ current northern limit in Scotland, established a regional chronology called WRATH-9. The chronology has been provisionally dated against Irish pine chronologies and provides the first annual resolution picture of Scots pine expansion from c. 3200 bc and subsequent demise from c. 3000 bc. Pine germination and growth is suggested to be associated with a widespread fall in bog water-tables that indicates a regional climatic control. Bog pines progressively declined in number, rather than died out in a single event, reflecting their growth in a marginal habitat, close to a critical ecological threshold. The use of tree-ring sequences from in situ bog pine macrofossils provides a higher resolution insight into past conditions than possible with existing radiocarbon and pollen-based chronologies.

Escalators, Elevators and Travelators: The Occupational Mobility of Migrants to South-East England

In a meritocratic society it is assumed that the chance of achieving occupational mobility (OM) is not strongly influenced by one's starting position in terms of class or ethnicity. This paper seeks to explain the drivers of the high levels of OM achieved by one ethnically defined group: the Scots. Educational attainment is shown to be particularly important. A second level of interest is the changing role of internal migrants to a global city in the face of increased international skilled immigration. We investigate whether there is any evidence that the OM of internal migrants is being hindered as a result. The evidence points instead to immobile local labour being more disadvantaged occupationally than mobile labour from peripheral regions of the state.

Botanical travel, climate and David Moore’s moral geographies of Europe

During his forty-year curatorship of the Royal Dublin Society's botanical gardens in Glasnevin (1838–1879), David Moore undertook a number of excursions to continental Europe. These served to deepen the networks of plant exchange between Dublin and other botanical institutions and allowed him to examine the relationships between climate, plant survivability and societal development. This paper focuses on two trips taken in the 1860s to Scandinavia and Iberia and charts how Moore situated his experience of these places within a climatic hermeneutic. Moore's understanding of northern and southern Europe was organized around a set of judgments about their relative backwardness or advancement with respect to his experience of home and was seen through the lens of a moral climatology. Moreover, his Scots Presbyterian background and his commitment to natural theology informed his interpretation of the landscapes he encountered in his excursions across Europe.

Clothing and Colonialism: The Dungiven costume and the fashioning of early modern identities

The entanglement of identity and personal attire in colonial settings is explored through consideration of a tattered set of clothes from late sixteenth-early seventeenth-century Ireland incorporating elements of Irish, English, and Scots fashion. Reconsideration of the clothing, recovered from a bog, provides a rare opportunity to explore the physical manifestations of processes of hybridity and mimesis, as well as the pragmatic accommodations of impoverishment and displacement in colonial settings. In addition to considering the role of material culture in colonial identity formation and negotiation, examination of what has become known as the Dungiven costume also speaks to the ongoing legacy of early modern colonial encounters, as the cultural associations of the garments, and by extension their past wearer(s), continue to be subjected to the politically charged nature of identity politics in contemporary Northern Ireland.

Hydroclimatic changes during the 8.2 ka event revealed by Irish pines

A pivotal cold event, deduced from the Greenland ice cores, took place between 8200 and 8000 cal. BP. Modelling of this climatic episode suggests that higher northern latitudes would have also experienced substantial reduction in rainfall and that Ireland would have observed a notable decline. No well-dated proxy record exists from the British Isles to test the model results. We present significant independent data for a phase of increased Scots pine initiation on Irish bogs at around 8150 cal. BP. Dendrochronological dating of sub-fossil Scots pine trees from three locations reveals synchronicity in germination across the area, indicative of a regional forcing, and allows for high-precision radiocarbon based dates. The starting rings of 40% of all samples from the north of Ireland dating to the period 8500-7500 cal. BP fall within a period of 25 years. The present colonisation model of Scots pine on peatland is interpreted as increasing drier conditions in the region and provides the first meaningful proxy data in support of a significant hydrological change in the north of Ireland accompanying the 8.2 ka event. The dating uncertainties associated with the Irish Scots pine record and the Greenland Ice Core Chronology 2005 (GICC05) do not allow for any overlap between the two. The results indicate that the discrepancy could be a result of dating inaccuracy that could have affected analysis of prior proxy alignments.

Religion, anti-slavery, and identity: Irish Presbyterians, the United States, and transatlantic evangelicalism, c. 1820-1914

Scholars have devoted much attention to the causes and consequences of Presbyterian emigration from Ulster to the thirteen colonies before 1776. This article moves beyond the eighteenth century to examine the continued religious links between Presbyterians in Ireland and the United States in the nineteenth century. It begins with an examination of the influence of evangelicalism on both sides of the Atlantic and how this promoted unity in denominational identity, missionary activity to convert Catholics, and revivalist religion during the first half of the century. Though Irish Presbyterians had great affection for their American co-religionists, they were not uncritical, and significant tensions did develop over slavery. The article then examines the religious character of Scotch-Irish or Ulster-Scots identity in the late nineteenth century, which was articulated in response to the alleged demoralising influence of large-scale Irish immigration during and after the Famine of the 1840s, the so-called Romanisation of Catholicism, and the threat of Home Rule in Ireland. The importance of identity politics should not obscure religious developments, and the article ends with a consideration of the origins and character of fundamentalism, perhaps one of the most important cultural connections between Protestants in Northern Ireland and the United States in the twentieth century.

'Anyone But England‘, Glasgow 2014 and the Independence Referendum: Exploring the Role of Narratives in the Sociological Study of Scottish Sport.

Drawing upon the findings of my MSc dissertation and the proposed methodology for my current PhD thesis, this paper will critically reflect upon the potential uses of narrative analysis within the sociological study of sport. The majority of this paper will consider the expression of anti-English sentiment by Scots in relation to both sporting and wider social contexts. Drawing upon the conceptual framework of ‘narrative identity’ proposed by Somers (1994), data was generated through semi-structured interviews focusing upon the ‘ontological’ and ‘public’ narratives of Scottish identity as expressed by Scots living in England. The relationship between Scotland and England is argued to be heavily influenced by the existence of an ‘underdog mentality’ grand ‘public narrative’ for Scots in relation to their English neighbours, based on perceived differences in economic and sporting resources. This ‘underdog mentality’ is argued to act as a legitimating force for the expression of anti-English sentiment within an individual’s ‘ontological narrative’ in both a sporting and wider social context. The paper concludes by reflecting upon the benefits of adopting a narrative analysis approach, and outlining the proposed use of similar methods within my PhD research on the 2014 Glasgow Commonwealth Games and the Scottish independence referendum.

Semi-destructive in situ tests as support to the assessment of a conservation process

This paper refers to the assessment on site by semi-destructive testing (SDT) methods of the consolidation efficiency of a conservation process developed by Henriques (2011) for structural and non-structural pine wood elements in service. This study was applied on scots pine wood (Pinus sylvestris L.) degraded by fungi after treatment with a biocidal product followed by consolidation with a polymeric product. This solution avoids substitutions of wood moderately degraded by fungi, improving its physical and mechanical characteristics. The consolidation efficiency was assessed on site by methods of drill resistance and penetration resistance. The SDT methods used showed good sensitivity to the conservation process and could evaluate their effectiveness. (C) 2015 Elsevier Ltd. All rights reserved.

James VI of Scotland Letter, 1579

This letter authorizes William Hamilton of Portmollart to repair to Edinburgh notwithstanding the acts discharging the Hamiltons from being within six miles of the King’s person. James VI and James I (June 19, 1566 – March 27, 1625) was King of Scots as James VI from July 24th, 1567 and King of England and Ireland as James I from the union of the English and Scottish crowns on March 24, 1603 after the passing of Elizabeth I.

Caractérisation des souches de Salmonella Typhimurium responsables de septicémies chez le porc

Depuis quelques années, il y a émergence de souches de Salmonella enterica sérovar Typhimurium multirésistantes causant une septicémie et la mort chez le porc. Ceci constitue un problème majeur pour l’industrie porcine et possiblement pour la santé publique. L’objectif de ce projet était de comparer et de caractériser une souche capable de causer une septicémie chez le porc et une souche commensale, en observant l’interaction avec des cellules épithéliales, des macrophages humains et d’identifier des gènes exprimés par les souches septicémiques et les souches commensales. Tout d’abord, l’infection de cellules épithéliales permet d’observer l’adhérence et l’invasion des bactéries, pour ainsi mettre en évidence la capacité des souches à coloniser le tractus gastro-intestinal. La souche commensale possède un pouvoir d’adhésion supérieur à la souche septicémique. Par la suite, l’infection de macrophages permet de caractériser le niveau de phagocytose et de survie. L’importance de la survie dans les macrophages pourrait permettre de faire un lien avec la septicémie. Toutefois, aucune différence n’est observable dans les conditions qui ont été testé. Ensuite, la technique SCOTS (Selective Capture of Transcribed Sequences) est utilisée pour capturer des gènes uniques à la souche septicémique et un autre SCOTS est fait pour capturer les gènes spécifiques à la souche commensale. Finalement, les gènes sont clonés, leur spécificité face aux souches est analysé par dot blot et ils sont identifiés par séquençage suivient d’une analyses bioinformatiques. Les gènes identifiés par SCOTS, lors des captures pour la souche septicémique et la souche commensale, se trouvent à être des gènes communs aux Salmonella. Toutefois, la différence de pathologie causée par les deux souches, n’est peut-être pas l’acquisition de nouveaux gènes, mais plutôt une différence d’expression entre les deux souches.

L’histoire au service de la politique : la chronique de Pierre de Langtoft et les tensions socio-culturelles en Angleterre fin XIIIe, début XIVe siècle

À la fin du XIIIe et au début du XIVe siècle, Édouard Ier (1239-1307), conquérant du Pays de Galles et de l'Écosse, semblait être en conflit perpétuel, que ce soit avec l’Écosse, la France ou le Pays de Galles. Il avait donc grandement besoin de financement. Or dès son règne, on sent que le Parlement avait acquis une importance particulière en Angleterre, de sorte qu’Édouard Ier devait le convaincre de lui accorder les taxes qu’il demandait. Des tensions socio-culturelles héritées de la conquête de 1066 compliquaient de beaucoup la tâche au roi qui se devait de trouver une solution pour unir toute la société anglaise contre ses ennemis. Le roi était également en conflit avec certains de ces sujets. C’était notamment le cas d’Antoine Bek, évêque palatin de Durham qui était menacé de perdre tous ses privilèges et libertés. Dans le but de se racheter auprès du roi, Bek demanda donc à Pierre de Langtoft, un moine du Nord de l’Angleterre, d’écrire une chronique dans laquelle il prêcherait l’union de toute la société anglaise contre les ennemis d’Édouard Ier. C’est celle-ci dont il est question dans ce mémoire, qui étudie la façon dont Pierre de Langtoft calomnie les ennemis du roi, surtout les Écossais et comment il utilise l’histoire pour plaider l’union de toutes les composantes de la société anglaise.
