AbstractUnderstanding factors that increase ecosystem stability is critical in the face of environmental change. Experiments simulating species loss from grassland ecosystems have shown that losing biodiversity decreases the ability of ecosystems to buffer negative effects of disturbances. However, as the originally sown experimental communities with reduced biodiversity develop, plant evolutionary processes or the assembly of interacting soil organisms may allow them to develop stability and resilience over time. We explored such effects in a long-term grassland biodiversity experiment with plant communities with either a history of co-occurrence (selected communities) or no such history (naïve communities) over a four-year period in which a major flood disturbance occurred.We found selected communities had temporally more stable biomass than the same communities of naïve plants, especially at low species richness. Furthermore, selected communities showed greater short-term biomass recovery after flooding, resulting in more stable post-flood productivity. In contrast to a previous study, the positive diversity–stability relationship was maintained after the flooding. Our results were consistent across three soil treatments simulating the presence or absence of co-selected microbial communities. We suggest that prolonged exposure of plant populations to a particular community context and abiotic site conditions can increase ecosystem temporal stability and resistance to disturbance. We argue that selection during the course of a biodiversity experiment is the most parsimonious explanation for these effects. A history of co-occurrence can in part compensate for species loss, as can high plant diversity in part compensate for the missing opportunity of such adaptive adjustments.

Mutualistic Networks

The biodiversity loss resulting from rising levels of human impacts on ecosystems has been extensively discussed over the last years. The expansion of urban areas promotes drastic ecological changes, especially through fragmentation of natural areas. Natural grassland remnants surrounded by an urban matrix are more likely to undergo disturbance events. Since grassland ecosystems are closely related to disturbances such as fire and grazing, grassland plant communities, pollinators, and their interaction networks may be especially sensitive to urban expansion, because it promotes habitat fragmentation and modifies disturbance regimes. This work evaluated the effect of the level of urbanization and recent history of fire disturbance on grassland plants communities and plant-floral visitor mutualistic networks. We sampled plant communities and floral visitors in 12 grassland sites with different levels of urbanization and time since the last fire event. Sites with higher levels of urbanization showed higher values for plant species richness, floral visitor richness, and network asymmetry. All sampled networks were significantly nested (with one exception), asymmetric, and specialized. In addition, all networks presented more modules than expected by chance. The frequency of fire disturbance events increased with the level of urbanization. Since grassland ecosystems depend on disturbances to maintain their structure and diversity, we inferred that the history of fire disturbance was the mechanism behind the relationship between urbanization and our biological descriptors. Our findings highlight the importance of small and isolated grassland remnants as conservation assets within urban areas, and that the disturbance events that such sites are submitted to may in fact be what maintains their diversity on multiple levels.

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.

The origins of attachment theory and the work of John Bowlby and Mary Ainsworth are described. Four types of child–parent attachment relationships—secure, insecure/anxious, insecure/ambivalent, and insecure/disorganized—are outlined along with the ways each type might manifest itself in the classroom. A longitudinal study, conducted by Alan Sroufe and his colleagues, of the development and effects on learning and interpersonal relationships of different child–parent attachment relationships is described. Teachers too have a history of attachment relationships that can affect how they relate to their students. The chapter describes adult attachment and how one’s attachment history might, positively or negatively, affect one’s ability to build positive, nurturing relationships with students. Specific examples of ways teachers can offset the negative effects of a student’s or their own history of insecure attachment are described.

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.

This epilogue argues that historians ought to be able to produce a universal history, one that would ‘cover’ the past of humankind ‘as a whole’. However, aside from the always increasing difficulty of mastering the factual material that such an undertaking requires, there exists another difficulty: the coherence of universal history always presupposes an initial decision not to write about the human past in all its multiplicity, but to focus on one aspect of that past. Nevertheless, the lure of universal history will persist, even in the face of its practical and conceptual difficulty. Certainly, it is possible to imagine a future ideological convergence among humans that would enable them to accept, as authoritative, one history of humankind.

For anyone interested in wildlife, birds, wilderness areas, parks, ecology, conservation, environmental literature, and ethics, the name Aldo Leopold is sure to pop up. Since first publication, Aldo Leopold: A Fierce Green Fire has remained the classic short, inspiring biography of Leopold--the perfect companion to reading his ever popular A Sand County Almanac. Winning numerous awards, this comprehensive account of his life story is dynamic and readable, written in the context of the history of American conservation and illustrated with historic photographs. Marybeth Lorbiecki has now enriched A Fierce Green Fire in a way no other biography on Leopold has, adding numerous chapters on the ripple effects of his ideas, books, ecological vision, land ethic, and Shack, as well as of the ecological contributions of his children, graduate students, contemporary scholars, and organizations--and the wilderness lands he helped preserve. Lorbiecki weaves these stories and factual information into the biography in a compelling way that keeps both lay and academic readers engaged. In the introduction to this edition, Lorbiecki makes it clear how much better our lives are because Leopold lived and why today we so radically need what he left us to bring about paradigm shifts in our ethical, economic, and cultural thinking. Instead of losing relevance, Leopold's legacy has gained ever more necessity and traction in the face of contemporary national and world challenges, such as species loss and climate change. Even the phenological studies he started at as a hobby are proving valuable, showing the climatic shifts that have occurred at the Shack lands since the 1930s, recognized by the plants and animals.

The COVID-19 pandemic is a serious challenge for societies around the globe as entire populations have fallen victim to the infectious spread and have taken up social distancing. In many countries, people have had to self-isolate and to be confined to their homes for several weeks to months to prevent the spread of the virus. Social distancing measures have had both negative and positive impacts on various aspects of economies, lifestyles, education, transportation, food supply, health, social life, and mental wellbeing. On other hands, due to reduced population movements and the decline in human activities, gas emissions decreased and the ozone layer improved; this had a positive impact on Earth’s weather and environment. Overall, the COVID-19 pandemic has negative effects on human activities and positive impacts on nature. This study discusses the impact of the COVID-19 pandemic on different life aspects including the economy, social life, health, education, and the environment.
