Lost at sea: Genetic, oceanographic and meteorological evidence for storm-forced dispersal

[EN] For many species, there is broad-scale dispersal of juvenile stages and/or long-distance migration of individuals and hence the processes that drive these various wide-ranging move- ments have important life-history consequences. Sea turtles are one of these paradigmatic long-distance travellers, with hatchlings thought to be dispersed by ocean currents and adults often shuttling between distant breeding and foraging grounds. Here, we use multi- disciplinary oceanographic, atmospheric and genetic mixed stock analyses to show that juvenile turtles are encountered ‘downstream’ at sites predicted by currents. However, in some cases, unusual occurrences of juveniles are more readily explained by storm events and we show that juvenile turtles may be displaced thousands of kilometres from their expected dispersal based on prevailing ocean currents.

Return to Hanging Rock: Lost Children in a Gothic Landscape

Using the philosophical position of phenomenology this article examines the ways in which ideas of wildness combine with Australian Gothic tropes such as the white colonial lost child and the bush as a haunted locale to compose key features of an Australian Ecogothic. Joan Lindsay’s enigmatic novel Picnic at Hanging Rock (1967) has prompted scholars such as Lesley Kathryn Hawkes to describe how in Australian literature for both adults and children ‘the environment is far more than a setting or backdrop against which the plot takes place’ (Hawkes, 2011,67). On St Valentine’s Day in 1900 three young Australian girls and their teacher disappear from a school picnic at the ancient site of Mount Macedon in Victoria. The analysis, which focuses on Lindsay’s posthumously published chapter eighteen (1987) examines how elements of the material, sensing world combine with the mythological or sacred to connect the human protagonists with the gothic landscape they inhabit. The resulting intersubjectivity problematizes colonial ideology and unsettles notions of national identity.

Re-viewing history: antiquaries, the graphic arts and Scotland's lost geographies, c.1660-1820

This thesis examines topographical art depicting Scotland’s natural scenery and built environments, architecture, antiquities and signs of modern improvement, made during the period 1660 to 1820. It sets out to demonstrate that topography and topographical art was not exclusively antiquarian in nature, but ranged across various fields of learning and practice. It included the work of artists, geographers, cartographers, travel writers, poets, landscape gardeners, military surveyors, naturalists and historians who were concerned with representing the country’s varied, and often contentious, histories within an increasingly modernising present. The visual images that are considered here were forms of knowledge that found expression in drawings, paintings and engravings, elevations, views and plans. They were made on military surveys and picturesque tours, and were often intended to be included alongside written texts, both published and unpublished, frequently connecting with travels, tours, memoirs, essays and correspondence. It will also be argued that topography was a social practice, involving networks of artists, collectors, publishers and writers, who exchanged information in drawings and letters in a nationwide, and often increasingly commercial enterprise. This thesis will explore some of the strands of such a vast network of picture-making that existed in Scotland, and Britain, between 1660 and 1820, as visual images were circulated, copied, recycled and adapted, and topographical and antiquarian visual culture emerges as a complex, synoptic form of inquiry.

Paradigms lost:integrating history and organization studies

This article reviews recent attempts at mapping research paradigms in Management and Organizational History and argues that the old distinctions between supplementarist, integrationist, and reorientationist approaches have been superseded by attempts at integrating historical research in organization studies. A typology of these integrationist approaches differentiates between pluralist and unitary integration, as well as between models based on either historical theory or organization theory. Each has distinct weaknesses and strengths, but essentially all limit their integration of historical research paradigms to only a few. As a result, there is a danger that history might become reduced to a methodology, an empirical endeavor, narrative representations, or indeed be considered the subject of research rather than a research approach in its own right. I argue that all of these present an impoverished picture of the rich research traditions available in the discipline of history, which has unique insights and approaches to offer to the study of organizations.

A kingdom near lost: English military recovery in Ireland, 1600-03

Ireland was rarely a peaceful realm for Elizabeth I, but Hugh O’Neill, Earl of Tyrone and his allies brought the edifice of English power in Ireland to the brink of collapse. The war in Ireland at the end of the sixteenth century devoured money, lives and reputations at a prodigious rate. However seven years of Irish success ended when in 1600 the Queen appointed Charles Blount, Lord Mountjoy as Lord Deputy. Success replaced failure, but only after the new Lord Deputy transformed English strategy and rebuilt the army into an instrument fit for purpose.

Lost in translation? The potential psychobiotic Lactobacillus rhamnosus (JB-1) fails to modulate stress or cognitive performance in healthy male subjects

Background: Preclinical studies have identified certain probiotics as psychobiotics a live microorganisms with a potential mental health benefit. Lactobacillus rhamnosus (JB-1) has been shown to reduce stress-related behaviour, corticosterone release and alter central expression of GABA receptors in an anxious mouse strain. However, it is unclear if this single putative psychobiotic strain has psychotropic activity in humans. Consequently, we aimed to examine if these promising preclinical findings could be translated to healthy human volunteers. Objectives: To determine the impact of L. rhamnosus on stress-related behaviours, physiology, inflammatory response, cognitive performance and brain activity patterns in healthy male participants. An 8 week, randomized, placebo-controlled, cross-over design was employed. Twenty-nine healthy male volunteers participated. Participants completed self-report stress measures, cognitive assessments and resting electroencephalography (EEG). Plasma IL10, IL1β, IL6, IL8 and TNFα levels and whole blood Toll-like 4 (TLR-4) agonist-induced cytokine release were determined by multiplex ELISA. Salivary cortisol was determined by ELISA and subjective stress measures were assessed before, during and after a socially evaluated cold pressor test (SECPT). Results: There was no overall effect of probiotic treatment on measures of mood, anxiety, stress or sleep quality and no significant effect of probiotic over placebo on subjective stress measures, or the HPA response to the SECPT. Visuospatial memory performance, attention switching, rapid visual information processing, emotion recognition and associated EEG measures did not show improvement over placebo. No significant anti-inflammatory effects were seen as assessed by basal and stimulated cytokine levels. Conclusions: L. rhamnosus was not superior to placebo in modifying stress-related measures, HPA response, inflammation or cognitive performance in healthy male participants. These findings highlight the challenges associated with moving promising preclinical studies, conducted in an anxious mouse strain, to healthy human participants. Future interventional studies investigating the effect of this psychobiotic in populations with stress-related disorders are required.

Lost fishing gear and litter at Gorringe Bank (NE Atlantic)

Studies concerning marine litter have received great attention over the last several years by the scientific community mainly due to their ecological and economic impacts in marine ecosystems, from coastal waters to the deep ocean seafloor. The distribution, type and abundance of marine litter in Ormonde and Gettysburg, the two seamounts of Gorringe Bank, were analyzed from photo and video imagery obtained during ROV-based surveys carried out at 60–3015 m depths during the E/V Nautilus cruise NA017. Located approximately 125 nm southwest of Portugal, Gorringe Bank lays at the crossroad between the Atlantic and the Mediterranean and is therefore characterized by an intense maritime traffic and fishing activities. The high frequency of lost or discarded fishing gear, such as cables, longlines and nets, observed on Gorringe Bank suggests an origin mostly fromfishing activities,with a clear turnover in the type of litter (mostly metal, glass and to amuch lesser extent, plastic) with increasing depth. Litter was more abundant at the summit of Gorringe Bank (ca. 4 items·km−1), decreasing to less than 1 item·km−1 at the flanks and to ca. 2 items·km−1 at greater depths. Nevertheless, litter abundance appeared to be lower than in continental margin areas. The results presented herein are a contribution to support further actions for the conservation of vulnerable habitats on Gorringe Bank so that they can continue contributing to fishery productivity in the surrounding region.
