Abstract

Marine heatwaves (MHWs) are discrete warm-water anomalies events occurring in every ocean around the globe, in both coastal and open ocean, having major impacts on ecosystems, fisheries and aquaculture. Although processes leading to MHWs formation are becoming more and more studied since the beginning of the 2010s, the way they interact together to trigger MHWs remains not fully understood. Nevertheless, their link to human-induced global warming tends to be certain. The southern part of Chile (41°5’S - 56°S) is characterized by fjord ecosystems already experiencing global warming consequences, whether large-scale or local climate modifications. However, to the best of our knowledge, MHWs occurrence in Southern Chile has never been subject to studies, despite the fjord ecosystem’s vulnerability to climate warming. Therefore, we assessed a global analysis of the MHWs that have occurred between 1982 and 2020 along Central and South coastal Chile, from 29°S to 55°S. We found that the last decade was record-breaking in terms of duration, intensity and occurrence of MHWs. In 2016, succession of MHWs during austral autumn, winter and spring lead to the formation of the longest (148 days, almost 5 months) and most extreme events (2.25°C above the climatology) ever recorded along Chile between 1982 and 2020. Those events were due to the advection of warm-waters anomalies coming from the open ocean and combination of persisting high pressure system with lower winds having led to reduced heat transfer from the ocean to the atmosphere. In addition, a global context of positive phases of El Niño Southern Oscillation and Southern Annular Mode contributed to the MHWs formation. Les vagues de chaleur marine, ou marine heatwaves (MHWs), sont des évènements discrets caractérisés par des eaux anormalement chaudes. Elles se produisent dans tous les océans, que ce soit en milieu côtier ou en pleine mer, et impactent fortement les écosystèmes marins, mais également les pêcheries et l’aquaculture. Bien que les processus menant à la formation de tels évènements soient de plus en plus étudiés depuis le début des années 2010, les interactions qu’ils ont entre eux pour conduire à la formation de MHWs restent encore relativement méconnues. Il est cependant de plus en plus certain que les MHWs sont liées au réchauffement climatique anthropique. Le sud du Chili (41°5’S – 46°S) est constitué d’un ensemble de fjords où les conséquences du réchauffement climatique se font déjà ressentir, que ce soient des modifications climatiques à l’échelle locale ou régionale. Cependant, d’après nos connaissances, il n’y a jamais eu d’étude portant sur les MHWs dans cette région du monde. Par conséquent, nous avons réalisé une étude globale des MHWs qui se sont produites entre 1982 et 2020 le long des côtes du Centre et du Sud du Chili, de 29°S à 55°S. Nous avons trouvé que la dernière décennie a été marquée par des MHWs particulièrement longues et fortes, et qu’elles se sont produites en plus grand nombre. En 2016, plusieurs MHWs se sont succédées de l’automne jusqu’au printemps australs, conduisant à la formation de la plus longue MHW (148 jours) et de la plus extrême (2.25°C au-dessus de la climatologie). Ces MHWs se sont produits suite au transport près des côtes d’eaux anormalement chaudes en provenance du Pacifique extratropical, associées à des hautes pressions stationnaires et une réduction des vents conduisant à une diminution des échanges de chaleur entre l’océan et l’atmosphère, en partie liés à des phases positives de El Niño Southern Oscillation et du Southern Annular Mode.

Abstract

In today’s society we increasingly create and consume written content and images. This includes a range of sources, from social media posts to records held within organisations, and everything in between, including news articles, blogs, shopping lists and official government documents. Critically reading these ‘documents’ can help us to understand a huge amount about society. Doing Excellent Social Research with Documents includes guidance on how to ‘read between the lines’, and provides an overview of six research projects which use documents as data.The substantive chapters are organised in two sections, with each chapter focused on a specific type of data. Section one focuses on documents that are found in isolation from their authors, including official and historical documents, traditional media, diaries and online content. Section two focuses on using documents in addition to existing data from primary research, including the role of documents in ethnography and visual research methods. In each chapter, you will be guided through the process of: Developing research questions, and how this impacts on which documents are selected; Considering aspects of bias and quality within the documentary sources; Undertaking analysis using six different strategies including thematic analysis, framework analysis, content analysis, discourse analysis and narrative analysis. Drawing on research projects which reflect real world situations, you will be methodically guided through the research process in detail, enabling you to examine and understand the practices and value of a range of documentary analysis approaches. Doing Excellent Social Research with Documents is a practical how-to guide for students (final year undergraduates onwards) and researchers using documents as data.

Abstract

Climate change poses a serious challenge to our health and wellbeing. The increasing frequency of extreme weather events such as floods, droughts, and heatwaves, and the direct impacts of changes in temperature have direct impacts on health. At the same time, broader environmental change affects infectious disease risk, air pollution, and other forms of exposure. The different ways in which climate change will affect health are complex, interactive, and different communities are disproportionately affected. International actions such as the Paris Agreement and the Sustainable Development Goals recognise the future risks to society and acknowledge that we are already committed to a certain level of climate change. Future adaptation measures therefore need careful assessment and implementation for us to be able to minimise the potential risks from climate change and, at the same time, maximise the potential health benefits of a cleaner, greener world. This Special Issue comprises original research articles and detailed reviews on the likely impacts of climate change on health in a range of geographical settings, and the potential for adaptation measures to reduce some of these risks. Ultimately, studies like these will motivate policy level action for mitigation and help in determining the most effective methods of adaptation to reduce negative impacts in future through embedding scientific evidence into practice.

Abstract

"The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world. The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth's greatest desert-including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara's origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert's ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes-such as prolonged droughts-upon the Sahara's geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert's surprising past to reflect on its present, as well as its possible future"--

Abstract

Several species of Dinophysis produce one or two groups of lipophilic toxins: okadaic acid (OA) and its derivatives; or the dinophysistoxins (DTXs) (also known as diarrhetic shellfish poisons or DSP toxins) and pectenotoxins (PTXs). DSP toxins are potent inhibitors of protein phosphatases, causing gastrointestinal intoxication in consumers of contaminated seafood. Forty years after the identification of Dinophysis as the causative agent of DSP in Japan, contamination of filter feeding shellfish exposed to Dinophysis blooms is recognized as a problem worldwide. DSP events affect public health and cause considerable losses to the shellfish industry. Costly monitoring programs are implemented in regions with relevant shellfish production to prevent these socioeconomic impacts. Harvest closures are enforced whenever toxin levels exceed regulatory limits (RLs). Dinophysis species are kleptoplastidic dinoflagellates; they feed on ciliates (Mesodinium genus) that have previously acquired plastids from cryptophycean (genera Teleaulax, Plagioselmis, and Geminigera) nanoflagellates. The interactions of Dinophysis with different prey regulate their growth and toxin production. When Dinophysis cells are ingested by shellfish, their toxins are partially biotransformed and bioaccumulated, rendering the shellfish unsuitable for human consumption. DSP toxins may also affect shellfish metabolism. This book covers diverse aspects of the abovementioned topics—from the laboratory culture of Dinophysis and the kinetics of uptake, transformation, and depuration of DSP toxins in shellfish to Dinophysis population dynamics, the monitoring and regulation of DSP toxins, and their impact on the shellfish industry in some of the aquaculture regions that are traditionally most affected, namely, northeastern Japan, western Europe, southern Chile, and New Zealand.

Abstract

"This book is the third in a trilogy that looks at the cultural history of Prague in order to tell the larger story of competing notions of European modernity-Reformation and Counter-Reformation, empire and nation, fascism and democracy-as they all played out on a single stage. This volume begins in 1938, when Czechoslovakia was dismembered by the Munich agreement and shortly before the invasion of the Third Reich, and it runs until the present day, when liberal democracy appears to be giving way to right-wing populism (as in much of the world). Like the previous volumes in the series, it sees Prague as a palimpsest of the cultures that overtook it-cultures that aimed to impose their own visions of modernity on the city. In this book, Sayer charts three major "modernities:" the Third Reich's brutal totalitarianism, the shifting face of Soviet communism, and the supposed freedoms of Western capitalist democracy. In Sayer's reading, the Nazis, Soviets, and Western democrats each believed that Prague had reached the end of history, that it had achieved "the final form of human government" (in Fukuyama's words). All were proved spectacularly wrong. As these political movements disintegrated, they returned the city to a state of banal surreality that Czech dissidents in the 1960s dubbed Absurdistan. Putting the notion of Absurdistan at the center of his story, Sayer engages with artists, creators and the things they produced, which unsparingly revealed the absurdity of the "modern" world and its notions of progress. He explores the work of Milan Kundera, Miloš Forman, Václav Havel, and many others lesser known in the Anglophone world. He examines the tradition of vulgar absurdist comedy beginning with Kafka, and he shows how Prague's cultural products have been marked by persistent moral ambiguity, or in Kundera's words, "the intoxicating relativity of human things," since the mid-century. The overarching argument of this book is that, by looking to Prague's cultural history, we can see that modernity has never been a single or stable notion, and as different ideologies of modernity have come head-to-head, they have produced a rich culture of ambiguity and absurdity. We published the first two books in the trilogy, The Coasts of Bohemia: A Czech History (1998), which spanned the 18th to the turn of the 20th century, and Prague, Capital of the Twentieth Century (2013), which looked at modernism and revolutionary thinking in Prague in the first half of the 20th century. Both books did well, and Prague, Capital of the Twentieth Century won the prestigious George L. Mosse Prize for European cultural and intellectual history from the American Historical Association"--
