Book Description
A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.

Book Description
Timothy Morton argues that ecological awareness in the present Anthropocene era takes the form of a strange loop or Möbius strip, twisted to have only one side. Deckard travels this oedipal path in Blade Runner (1982) when he learns that he might be the enemy he has been ordered to pursue. Ecological awareness takes this shape because ecological phenomena have a loop form that is also fundamental to the structure of how things are. The logistics of agricultural society resulted in global warming and hardwired dangerous ideas about life-forms into the human mind. Dark ecology puts us in an uncanny position of radical self-knowledge, illuminating our place in the biosphere and our belonging to a species in a sense that is far less obvious than we like to think. Morton explores the logical foundations of the ecological crisis, which is suffused with the melancholy and negativity of coexistence yet evolving, as we explore its loop form, into something playful, anarchic, and comedic. His work is a skilled fusion of humanities and scientific scholarship, incorporating the theories and findings of philosophy, anthropology, literature, ecology, biology, and physics. Morton hopes to reestablish our ties to nonhuman beings and to help us rediscover the playfulness and joy that can brighten the dark, strange loop we traverse.

Book Description
In this book—one of the first ecocritical explorations of Irish literature—Alison Lacivita defies the popular view of James Joyce as a thoroughly urban writer by bringing to light his consistent engagement with nature. Using genetic criticism to investigate Joyce’s source texts, notebooks, and proofs, Lacivita shows how Joyce developed ecological themes in Finnegans Wake over successive drafts. Making apparent a love of growing things and a lively connection with the natural world across his texts, Lacivita’s approach reveals Joyce’s keen attention to the Irish landscape, meteorology, urban planning, Dublin’s ecology, the exploitation of nature, and fertility and reproduction. Alison Lacivita unearths a vital quality of Joyce’s work that has largely gone undetected, decisively aligning ecocriticism with both modernism and Irish studies.

Book Description
Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences.

Book Description
Ecology, Ethics, and Hope explores what hope is, how it operates, and whether or not it is important in our response to ecological challenges like climate change, deforestation, biodiversity loss, and pollution. The book offers an accessible and timely overview of this emerging topic within environmental ethics, a platform for further discussion, and refinement of the notion of hope. Hope has started to receive more theoretical attention from philosophers and social scientists. In light of worsening ecological conditions, the concept of hope may offer motivation for us to change our destructive ways and conserve the ecosystem goods and systems we depend on. The authors in this collection take stock of the various accounts of what hope is (or is not), what it does (or does not), and how relevant it is to ecological thinking. The book covers topics including the psychology of hope (how it might operate and change minds), hope as a motivator of positive action, and hope’s essence in the context of a virtue- or obligation-focused morality.

Book Description
Increased throughput of carbon-based fossil energy, the destruction of Earth’s forests, and other land use changes have resulted in ever higher levels of waste in the form of greenhouse gases—as well as a diminished capacity of the planet to absorb and store those wastes. This means that to avoid catastrophic global warming and maintain the habitability of Earth by protecting essential soil and water resources, we will need to not only reduce emissions, but also increase carbon storage in the land system. Biosequestration and Ecological Diversity: Mitigating and Adapting to Climate Change and Environmental Degradation discusses ways to remove greenhouse gases from the atmosphere and build soil by changing the way people use and manage land. Principles and Practices for Better Land Management Examining biosequestration in social, economic, and political context, the book reviews recent scientific evidence on climate change and global ecological degradation and explains how the carbon cycle has been transformed by destructive land use practices, such as deforestation and the burning of fossil fuels. It describes the principles of biosequestration and restorative land management practices and discusses the potential of carbon storage. The author offers specific examples of inexpensive, proven practices that build soil, protect scarce water resources, and enhance ecological diversity. He also identifies conservation policies that provide technical assistance and financial resources for ecological protection and restoration. How You Can Help Mitigate Climate Change with a Little Piece of Land Restorative land use and land management practices are critical components of any comprehensive strategy for mitigating and adapting to climate change and global environmental degradation. This book explains how anyone who owns or manages land—from an apartment to a city lot to a farm, forest, park, or even a golf course—can help protect and enhance the biological sequestration of carbon.

Book Description
Margaret A. Syverson discusses the ways in which a theory of composing situations as ecological systems might productively be applied in composition studies. She demonstrates not only how new research in cognitive science and complex systems can inform composition studies but also how composing situations can provide fruitful ground for research in cognitive science. Syverson first introduces theories of complex systems currently studied in diverse disciplines. She describes complex systems as adaptive, self-organizing, and dynamic; neither utterly chaotic nor entirely ordered, these systems exist on the boundary between order and chaos. Ecological systems are "metasystems" composed of interrelated complex systems. Writers, readers, and texts, together with their environments, constitute one kind of ecological system. Four attributes of complex systems provide a theoretical framework for this study: distribution, embodiment, emergence, and enaction. Three case studies provide evidence for the application of these concepts: an analysis of a passage from an autobiographical poem by Charles Reznikoff, a study of first-year college students writing collaboratively, and a conflict in a computer forum of social scientists during the Gulf War. The diversity of these cases tests the robustness of theories of distributed cognition and complex systems and suggests possibilities for wider application. Syverson concludes with a discussion of some implications of an ecological approach for composition research, pedagogy, and assessment, presenting the Learning Record model as one practical application of the theory. Finally she argues that technological changes have created new environmentsfor composing, providing an opportunity to reconsider conventional environments as well.

Book Description
Progress requires the conquest of nature. Or does it? This startling new account overturns conventional interpretations of Marx and in the process outlines a more rational approach to the current environmental crisis. Marx, it is often assumed, cared only about industrial growth and the development of economic forces. John Bellamy Foster examines Marx's neglected writings on capitalist agriculture and soil ecology, philosophical naturalism, and evolutionary theory. He shows that Marx, known as a powerful critic of capitalist society, was also deeply concerned with the changing human relationship to nature. Marx's Ecology covers many other thinkers, including Epicurus, Charles Darwin, Thomas Malthus, Ludwig Feuerbach, P. J. Proudhon, and William Paley. By reconstructing a materialist conception of nature and society, Marx's Ecology challenges the spiritualism prevalent in the modern Green movement, pointing toward a method that offers more lasting and sustainable solutions to the ecological crisis.
