How the science of complexity can help save the natural world from collapse.

Slack enjoyed full access to Hutchinson's archives and conducted extensive interviews both with Hutchinson himself and with his students, colleagues, and friends. She evaluates his contributions to theoretical ecology, limnology (the study of fresh-water ecosystems), biogeochemistry, population ecology, and the creation of the new fields of systems ecology and radiation ecology, and she discusses his profound influence as a mentor. The book also looks into his personal life, which included three very different wives, a refugee baby under his care during World War II, friendships with such contemporaries as Rebecca West, Margaret Mead, and Gregory Bateson, and a host of colleagues and friends on four continents. Filled with information available nowhere else, this book draws a vibrant portrait of a giant in the discipline of twentieth-century ecology who was also a man of remarkable personal appeal. --Book Jacket.

There have been many well-publicized cases of invasive species of plants and animals, often introduced unintentionally but sometimes on purpose, causing widespread ecological havoc. Examples of such alien invasions include pernicious weeds such as Japanese knotweed, an introduced garden ornamental which can grow through concrete, the water hyacinth which has choked tropical waterways, and many introduced animals which have out-competed and displaced local fauna. This book addresses the broader context of invasive and exotic species, in terms of the perceived threats and environmental concerns which surround alien species and ecological invasions. As a result of unprecedented scales of environmental change, combined with rapid globalisation, the mixing of cultures and diversity, and fears over biosecurity and bioterrorism, the known impacts of particular invasions have been catastrophic. However, as several chapters show, reactions to some exotic species, and the justifications for interventions in certain situations, including biological control by introduced natural enemies, rest uncomfortably with social reactions to ethnic cleansing and persecution perpetrated across the globe. The role of democracy in deciding and determining environmental policy is another emerging issue. In an increasingly multicultural society this raises huge questions of ethics and choice. At the same time, in order to redress major ecological losses, the science of reintroduction of native species has also come to the fore, and is widely accepted by many in nature conservation. However, with questions of where and when, and with what species or even species analogues, reintroductions are acceptable, the topic is hotly debated. Again, it is shown that many decisions are based on values and perceptions rather than objective science. Including a wide range of case studies from around the world, his book raises critical issues to stimulate a much wider debate.

Song, Landscape, and Identity in Medieval Northern France offers a new perspective on how medieval song expressed relationships between people and their environments. Informed by environmental history and harnessing musicological and ecocritical approaches, author Jennifer Saltzstein draws connections between the nature imagery that pervades songs written by the trouvères of northern France to the physical terrain and climate of the lands on which their authors lived. In doing so, she analyzes the different ways in which composers' lived environments related to their songs and categorizes their use of nature imagery as realistic, aspirational, or nostalgic. Demonstrating a cycle of mutual impact between nature and culture, Saltzstein argues that trouvère songs influenced the ways particular groups of medieval people defined their identities, encouraging them to view themselves as belonging to specific landscapes. The book offers close readings of love songs, pastourelles, motets, and rondets from the likes of Gace Brulé, Adam de la Halle, Guillaume de Machaut, and many others. Saltzstein shows how their music-text relationships illuminate the ways in which song helped to foster identities tied to specific landscapes among the knightly classes, the clergy, aristocratic women, and peasants. By connecting social types to topographies, trouvère songs and the manuscripts in which they were preserved presented models of identity for later generations of songwriters, performers, listeners, patrons, and readers to emulate, thereby projecting into the future specific ways of being on the land. Written in the long thirteenth century during the last major era of climate change, trouvère songs, as Saltzstein demonstrates, shape our understanding of how identity formation has rested on relationships between nature, culture, and change.

Ecological degradation has been an object of concern for the international community since the early 1970s, but legal approaches that have been employed to improve the protection of ecosystems have failed to halt this decline. Ecological Governance explores how the law should respond to this rapid global deterioration of ecosystems by examining the foundational scientific and ethical considerations for designing laws that are effective for ecological protection. Based on these analyses, it argues that developed states should prioritise the reduction of the ecological stresses for which they are responsible in decision-making on their future courses. The author also proposes structures for governance and associated legal frameworks that would enable the formulation and implementation of policies for ecological sustainability.
