Among Western Palaearctic birds, range expansion is more commonly observed in families with low proportions of long-distance migrants than among generally migratory families. Migrants are also disproportionately scarce in the Irish avifauna, compared with that of Britain, and scarcer among colonists of Britain than among long-established species. Colonization attempts in southeast England and in Scotland have more frequently resulted in establishment by the invader than have attempts in areas more remote from the European mainland; in several cases, these attempts have followed a history of range expansion and/or population increase in the source areas. Successful colonists lay more eggs each season, on average, than failed colonists; this difference is due, in part, to larger clutches and in part to more clutches per season. The failure of migrants to make successful invaders is attributed to their inability to compete for resources, especially habitat, in the face of competition from year-round residents. The findings otherwise agree well with predictions of the MacArthur-Wilson theory of island colonization.

To combat high dropout rates and low motivation for online courses, we gamified a history of science course. To do so, we used an online educational program called 3DGameLab to convert what had been a well-liked face-to-face lecture and discussion course to an online format, for the purposes of long-distance teaching and learning. Within 3DGameLab, we prepared approximately three times as much content as would be taught in a face-to-face class. Clear tasks and immediate rewards in the form of experience points (XP) contributed to a transparent motivational system as compared to traditional grading. In this course, students completed their assignments asynchronously. Sustaining engagement is challenging in this format due to student self-management, but, with the game mode, students could repeat their attempts to pass a quest (a lesson) until they succeed (submit a passable response). The feedback cycle was short, and we found that students tend to persevere in the face of failure when they get rapid feedback, rather than quit. To test the adaptability of the asynchronous, gamified format, we also designed this course as a hybrid course. Students remained engaged when the feedback was quick, and the tasks were clearly set. We did not perform a quantitative study; the purpose of this article is to share a design study of our methods and subsequent experience with these modalities.

Slow Evolution

Predicting how and when adaptive evolution might rescue species from global change, and integrating this process into tools of biodiversity forecasting, has now become an urgent task. Here, we explored whether recent population trends of species can be explained by their past rate of niche evolution, which can be inferred from increasingly available phylogenetic and niche data. We examined the assemblage of 409 European bird species for which estimates of demographic trends between 1970 and 2000 are available, along with a species-level phylogeny and data on climatic, habitat and trophic niches. We found that species' proneness to demographic decline is associated with slow evolution of the habitat niche in the past, in addition to certain current-day life-history and ecological traits. A similar result was found at a higher taxonomic level, where families prone to decline have had a history of slower evolution of climatic and habitat niches. Our results support the view that niche conservatism can prevent some species from coping with environmental change. Thus, linking patterns of past niche evolution and contemporary species dynamics for large species samples may provide insights into how niche evolution may rescue certain lineages in the face of global change.

Modernization of agriculture, economic development and population increase after the end of the Thirty Years' War caused authorities in many parts of Germany to decree the eradication of so-called pest animals, including the House Sparrow. Farmers were given targets, and had to deliver the heads of sparrows in proportion to the size of their farms or pay fines. At the end of the eighteenth century German ornithologists argued against the eradication of the sparrows. During the mid-nineteenth century, C. L. Gloger, the pioneer of bird protection in Germany, emphasized the value of the House Sparrow in controlling insect plagues. Many decrees were abolished because either they had not been obeyed, or had resulted in people protecting sparrows so that they always had enough for their “deliveries”. Surprisingly, various ornithologists, including Ernst Hartert and the most famous German bird conservationist Freiherr Berlepsch, joined in the war against sparrows at the beginning of the twentieth century, because sparrows were regarded as competitors of more useful bird species. After the Second World War, sparrows were poisoned in large numbers. Persecution of sparrows ended in Germany in the 1970s. The long period of persecution had a significant but not long-lasting impact on House Sparrow populations, and therefore cannot be regarded as a factor in the recent decline of this species in urban and rural areas of western and central Europe.

The Protestant Work Ethic

This article begins by outlining contemporary anti-work politics, which form the basis of Sandford’s reading. After providing a brief history of anti-work politics, Sandford examines recent scholarly treatments of Jesus’ relationship to work. An examination of a number of texts across the gospel traditions leads Sandford to argue that Jesus can be read as a ‘luxury communist’ whose behaviour flies in the face of the Protestant work ethic. Ultimately, Sandford foregrounds those texts in which Jesus discourages his followers from working, and undermines work as an ‘end in itself’, contextualising these statements in relation to other gospel texts about asceticism and the redistribution of wealth.

Results from the monitoring programs of the Swiss Ornithological Institute show that the breeding populations of several forest species for which deadwood is an important habitat element (black woodpecker, great spotted woodpecker, middle spotted woodpecker, lesser spotted woodpecker, green woodpecker, three-toed woodpecker as well as crested tit, willow tit and Eurasian tree creeper) have increased in the period 1990 to 2008, although not to the same extent in all species. At the same time the white-backed woodpecker extended its range in eastern Switzerland. The Swiss National Forest Inventory shows an increase in the amount of deadwood in forests for the same period. For all the mentioned species, with the exception of green and middle spotted woodpecker, the growing availability of deadwood is likely to be the most important factor explaining this population increase.

Modernist literature is inextricable from the history of obscenity. The trials of such figures as James Joyce, D. H. Lawrence, and Radclyffe Hall loom large in accounts of twentieth-century literature. Filthy Material: Modernism and the Media of Obscenity reveals the ways that debates about obscenity and literature were shaped by changes in the history of media. The emergence of film, photography, and new printing technologies shaped how “literary value” was understood, altering how obscenity was defined and which texts were considered obscene. Filthy Material rereads the history of modernist obscenity to discover the role played by technological media in debates about obscenity. The shift from the intense censorship of the early twentieth century to the effective “end of obscenity” for literature at the middle of the century was not simply a product of cultural liberalization but also of a changing media ecology. Filthy Material brings together media theory and archival research to offer a fresh account of modernist obscenity with novel readings of works of modernist literature. It sheds new light on figures at the center of modernism’s obscenity trials (such as Joyce and Lawrence), demonstrates the relevance of the discourse of obscenity to understanding figures not typically associated with obscenity debates (such as T. S. Eliot and Wyndham Lewis), and introduces new figures to our account of modernism (such as Norah James and Jack Kahane). It reveals how modernist obscenity reflected a contest over the literary in the face of new media technologies.

The pericope adulterae (John 7:53–8:11) is often interpreted as an inherently feminist story, one that validates women’s humanity in the face of a patriarchal order determined to reduce sexual sinners and women more generally to the status of object. Reading this story within a framework of queer narratology, however, leads to a different point of view, one that challenges the consequences of seeking rescue from a god and a text that are both quite willing to forge male homosocial bonds at a woman’s expense. As the history of this story also shows, texts and their meanings remain unsettled and therefore open to further unpredictable and contingent elaboration. Pondering my own feminist commitments, I attempt to imagine a world and a story where a woman is a person and Jesus is in need of rescue. Perhaps such a world is possible. Or perhaps it is not.

The Individual

This book contains an analysis of the experience of married life by men and women in Christian medieval Europe c. 900–1300. The focus will be on the social and emotional life of the married couple rather than on the institutional history of marriage. The book consists of three parts: the first part (Getting Married) is devoted to the process of getting married and wedding celebrations, the second part (Married Life) discusses the married life of lay couples and clergy, their sexuality, and any remarriage, while the third part (Alternative Living) explores concubinage and polygyny as well as the single life in contrast to monogamous sexual unions. Four main themes are central to the book. First, the tension between patriarchal family strategies and the individual family member’s freedom of choice to marry and, if so, to what partner; second, the role played by the married priesthood in their quest to have individual agency and self-determination accepted in their own lives in the face of the growing imposition of clerical celibacy; third, the role played by women in helping society accept some degree of gender equality and self-determination to marry and in shaping the norms for married life incorporating these principles; fourth, the role played by emotion in the establishment of marriage and in married life at a time when sexual and spiritual love feature prominently in medieval literature.

Renaissance Mass Murder explores the devastating impact of war on the men and women of the Renaissance. In contrast to the picture of balance and harmony usually associated with the Renaissance, it uncovers in forensic detail a world in which sacks of Italian cities and massacres of civilians at the hands of French, German, Spanish, Swiss, and Italian troops were regular occurrences. The arguments presented are based on a wealth of evidence—histories and chronicles, poetry and paintings, sculpture and other objects—which together provide a new and startling history of sixteenth-century Italy and a social history of the Italian Wars. It outlines how massacres happened, how princes, soldiers, lawyers, and writers, justified and explained such events, and how they were represented in contemporary culture. On this basis the book reconstructs the terrifying individual experiences of civilians in the face of war and in doing so offers a story of human tragedy which redresses the balance of the history of the Italian Wars, and of Renaissance warfare, in favour of the civilian and away from the din of the battlefield. This book also places mass murder in a broader historical context and challenges claims that such violence was unusual or in decline in early modern Europe. Finally, it shows that women often suffered disproportionately from this violence and that immunity for them, as for their children, was often partially developed or poorly respected.
