Natural history of Arabidopsis thaliana and oomycete symbioses

Molecular ecology of plant–microbe interactions has immediate significance for filling a gap in knowledge between the laboratory discipline of molecular biology and the largely theoretical discipline of evolutionary ecology. Somewhere in between lies conservation biology, aimed at protection of habitats and the diversity of species housed within them. A seemingly insignificant wildflower called Arabidopsis thaliana has an important contribution to make in this endeavour. It has already transformed botanical research with deepening understanding of molecular processes within the species and across the Plant Kingdom; and has begun to revolutionize plant breeding by providing an invaluable catalogue of gene sequences that can be used to design the most precise molecular markers attainable for marker-assisted selection of valued traits. This review describes how A. thaliana and two of its natural biotrophic parasites could be seminal as a model for exploring the biogeography and molecular ecology of plant–microbe interactions, and specifically, for testing hypotheses proposed from the geographic mosaic theory of co-evolution

Reflective interventionist conversation analysis

© The Author(s) 2020. A distinction has been drawn between basic (pure) conversation analysis (CA) and applied CA. Applied CA has become especially beneficial for informing areas of practice such as health, social care and education, and is an accepted form of research evidence in the scientific rhetoric. There are different ways of undertaking applied CA, with different foci and goals. In this article, we articulate one way of conducting applied CA, that is especially pertinent for practitioners working in different fields. We conceptualise this as Reflective Interventionist CA (RICA). We argue that this approach to applied CA is important because of its emphasis on the reflective stance that is valuable to an understanding of research data, its commitment to collaboration with practitioners, and its inductive style. In this paper, we outline the core premises and benefits of this approach and offer empirical examples to support our argument. To conclude, we consider the implications for evidence-based practice

Contribution of Alaskan glaciers to sea level rise derived from satellite imagery

International audienceOver the last 50 years, retreating glaciers and ice caps (GIC) contributed 0.5 mm/yr to sea level rises (SLR), and one third is believed to originate from ice masses bordering the Gulf of Alaska. However, these estimates of ice wastage in Alaska are based on methods that measure a limited number of glaciers and extrapolate the results to estimate ice loss for the many thousands of others. How these methods capture the complex pattern of decadal elevation changes at the scale of individual glacier and mountain range is unclear. Here, combining a comprehensive glacier inventory with elevation changes derived from sequential digital elevation models (DEMs), we found that, between 1962 and 2006, Alaskan glaciers lost 41.9 ± 8.6 km**3/yr water equivalent (w.e.) and contributed 0.12±0.02 mm/yr to SLR. Our ice loss is 34% lower than previous estimates. Reasons for our lower values include the higher spatial resolution of our glacier inventory and the reduction of ice thinning under debris and at the glacier margins which were not resolved in earlier work. Estimates of mass loss from GIC in other mountain regions could be subject to similar revisions

Iconic dishes, culture and identity: the Christmas pudding and its hundred years’ journey in the USA, Australia, New Zealand and India

Asserting that recipes are textual evidences reflecting the society that produced them, this article explores the evolution of the recipes of the iconic Christmas pudding in the United States, Australia, New Zealand and India between the mid-nineteenth and the mid-twentieth centuries. Combining a micro-analysis of the recipes and the cookbook that provided them with contemporary testimonies, the article observes the dynamics revealed by the preparation and consumption of the pudding in these different societies. The findings demonstrate the relevance of national iconic dishes to the study of notions of home, migration and colonization, as well as the development of a new society and identity. They reveal how the preservation, transformation and even rejection of a traditional dish can be representative of the complex and sometimes conflicting relationships between colonists, migrants or new citizens and the places they live in

Apocalyptic public health: exploring discourses of fatness in childhood ‘obesity’ policy

Recent‘ obesity’ preventions focus heavily on children, widely regarded as the future of society. The National Child Measurement Programme (NCMP) is a flagship government programme in England that annually measures the Body Mass Index (BMI) of children in Reception (aged 4–5) and Year 6 (aged 10 –11) in order to identify ‘at risk’ children and offer advice to parents. Using Foucauldian discourse analysis this study explore show discourses within the programme construct fatness. The NCMP materials contain three key interrelated themes (concerning the hidden threat of ‘obesity’, the burden of ‘obesity’, and bodies that pose a greater risk) that combine to construct a ‘grotesque discourse’ of apocalyptic public health. ‘Obesity’ is constructed as a social and economic catastrophe where certain bodies pose a greater threat than others. We argue that this discourse has the potential to change health service policy in markedly regressive ways that will disproportionately impact working-class, Black, Asian, and mixed race families

The Art of Living in Australia - Cover Image

The Art of Living in Australia was first published in 1893 and urged the value of Mediterranean eating and drinking habits for the Australian way of life. An experienced physician, Philip E. Muskett promoted healthy living habits appropriate for the climate and conditions of 19th century Australia, including the best clothing, household arrangements, necessary exercise and a healthy diet. Finding a resemblance between the conditions of southern Europe, he implores white Australians to eat more vegetables and less meat, in the style of those from the Mediterranean.The book also contains over 300 recipes contributed by Mrs Wicken, lecturer in charge of ‘domestic economy’ at Sydney Technical College, including for salads, vegetable dishes, seafood and sweets. This new edition includes the original index, plus facsimiles of pages of historical interest from the 1893 edition
