Book Summary:

John Muir called it the "Range of Light, the most divinely beautiful of all the mountain chains I’ve ever seen." The Sierra Nevada—a single unbroken mountain range stretching north to south over four hundred miles, best understood as a single ecosystem but embracing a number of environmental communities—has been the site of human activity for millennia. From the efforts of ancient Native Americans to encourage game animals by burning brush to create meadows to the burgeoning resort and residential development of the present, the Sierra has endured, and often suffered from, the efforts of humans to exploit its bountiful resources for their own benefit. Historian David Beesley examines the history of the Sierra Nevada from earliest times, beginning with a comprehensive discussion of the geologic development of the range and its various ecological communities. Using a wide range of sources, including the records of explorers and early settlers, scientific and government documents, and newspaper reports, Beesley offers a lively and informed account of the history, environmental challenges, and political controversies that lie behind the breathtaking scenery of the Sierra. Among the highlights are discussions of the impact of the Gold Rush and later mining efforts, as well as the supporting industries that mining spawned, including logging, grazing, water-resource development, market hunting, urbanization, and transportation; the politics and emotions surrounding the establishment of Yosemite and other state and national parks; the transformation of the Hetch Hetchy into a reservoir and the desertification of the once-lush Owens Valley; the roles of the Forest Service, Park Service, and other regulatory agencies; the consequences of the fateful commitment to wildfire suppression in Sierran forests; and the ever-growing impact of tourism and recreational use. Through Beesley’s wide-ranging discussion, John Muir’s "divinely beautiful" range is revealed in all its natural and economic complexity, a place that at the beginning of the twenty-first century is in grave danger of being loved to death. Available in hardcover and paperback.

Book Summary:

The rural west is at a crossroads, and the Sierra Nevada is at the center of this social and economic change. The Sierra Nevada landscape has always been valued for its bounty of natural resource commodities, but new residents and an ever-growing flood of tourists to the area have transformed the relationship between the region's nature and its culture. In an engaging narrative that melds the personal with the professional, Timothy P. Duane—who grew up in the area—documents the impact of rapid population growth on the culture, economy, and ecology of the Sierra Nevada since the late 1960s. He also recommends innovative policies for mitigating the negative effects of future population growth in this spectacular but threatened region, as well as throughout the rural west. Today, the primary social and economic values of the Sierra Nevada landscape are in the amenities and ecological services provided by its wildlands and functioning ecosystems. Duane shows how further unfettered population growth threatens the very values which have made the Sierra Nevada a desirable place to live and work. A new approach to land use planning, resource management, and local economic development—one that recognizes the emerging values of the landscape—is necessary in order to achieve sustainable development, Duane claims. Weaving personal experience with outstanding scholarship, he shows how such an approach must explicitly recognize the importance of values and the application of an environmental land ethic to future development in the area.

Book Summary:

Smokescreen cuts through years of misunderstanding and misdirection to make an impassioned, evidence-based argument for a new era of forest management for the sake of the planet and the human race. Natural fires are as essential as sun and rain in fire-adapted forests, but as humans encroach on wild spaces, fear, arrogance, and greed have shaped the way that people view these regenerative events and given rise to misinformation that threatens whole ecosystems as well as humanity's chances of overcoming the climate crisis. Scientist and activist Chad T. Hanson explains how natural alarm over wildfire has been marshaled to advance corporate and political agendas, notably those of the logging industry. He also shows that, in stark contrast to the fear-driven narrative around these events, contemporary research has demonstrated that forests in the United States, North America, and around the world have a significant deficit of fire. Forest fires, including the largest ones, can create extraordinarily important and rich wildlife habitats as long as they are not subjected to postfire logging. Smokescreen confronts the devastating cost of current policies and practices head-on and ultimately offers a hopeful vision and practical suggestions for the future -- one in which both communities and the climate are protected and fires are understood as a natural and necessary force.

Book Summary:

As the twenty-first century dawns, public land policy is entering a new era. This timely book examines the historical, scientific, political, legal, and institutional developments that are changing management priorities and policies—developments that compel us to view the public lands as an integrated ecological entity and a key biodiversity stronghold. Once the background is set, each chapter opens with a specific natural resource controversy, ranging from the Pacific Northwest’s spotted owl imbroglio to the struggle over southern Utah’s Colorado Plateau country. Robert Keiter uses these case histories to analyze the ideas, forces, and institutions that are both fomenting and retarding change. Although Congress has the final say in how the public domain is managed, the public land agencies, federal courts, and western communities are each playing important roles in the transformation to an ecological management regime. At the same time, a newly emergent and homegrown collaborative process movement has given the public land constituencies a greater role in administering these lands. Arguing that we must integrate the new imperatives of ecosystem science with our devolutionary political tendencies, Keiter outlines a coherent new approach to natural resources policy.

Evolution through Genetic Exchange

Book Summary:

Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphor as a more appropriate representation of evolutionary change in all lifeforms. This research level text is suitable for senior undergraduate and graduate level students taking related courses in departments of genetics, ecology and evolution. It will also be of relevance and use to professional evolutionary biologists and systematists seeking a comprehensive and authoritative overview of this rapidly expanding field.

Book Summary:

In a Dark Wood presents a history of debates among ecologists over what constitutes good forestry, and a critique of the ecological reasoning behind contemporary strategies of preservation, including the Endangered Species Act. Chase argues that these strategies, in many instances adopted for political, rather than scientific reasons, fail to promote biological diversity and may actually harm more creatures than they help. At the same time, Chase offers examples of conservation strategies that work, but which are deemed politically incorrect and ignored. In a Dark Wood provides the most thoughtful and complete account yet written of radical environmentalism. And it challenges the fundamental—but largely unexamined—assumptions of preservationism, such as those concerning whether there is a "balance of nature," whether all branches of ecology are really science, and whether ecosystems exist. In his new introduction, Chase evaluates the response to his book and reports on recent developments in environmental science, policy, and politics. In a Dark Wood was judged by a recent national poll to be one of the one hundred best nonfiction books written in the English language during the twentieth century. A smashing good read, this book will be of interest to environmentalists, ecologists, philosophers, biologists, and bio-ethicists, and anyone concerned about ecological issues.

Book Summary:

This book, companion to Foundations of Location Analysis (Springer, 2011), highlights some of the applications of location analysis within the spheres of businesses, those that deal with public services and applications that deal with law enforcement and first responders. While the Foundations book reviewed the theory and first contributions, this book describes how different location techniques have been used to solve real problems. Since many real problems comprise multiple objectives, in this book there is more presence of tools from multicriteria decision making and multiple-objective optimization. The section on business applications looks at such problems as locating bank branches, the potential location of a logistics park, sustainable forest management and layout problems in a hospital, a much more difficult type of problem than mere location problems. The section on public services presents chapters on the design of habitats for wildlife, control of forest fires, the location of intelligent sensors along highways for timely emergency response, locating breast cancer screening centers, an economic analysis for the locations of post offices and school location. The final section of the book includes chapters on the well-known problem of locating fire stations, a model for the location of sensors for travel time information, the problem of police districting, locations of jails, location of Coast Guard vessels and finally, a survey of military applications of location analysis throughout different periods of recent history.

Book Summary:

Taking Complexity Seriously applies the advanced policy analysis technique of triangulation to what is now the world's most complex public policy challenge: sustainable development. One central problem of public policy analysis has been to find new ways of analyzing issues of increasing complexity and uncertainty. Triangulation is perhaps the best example of these novel techniques, as it uses various methods, databases, theories, and approaches to converge on what to do about the complex issue in question. Taking Complexity Seriously uses four different theoretical approaches (Girardian economics, cultural theory, critical theory, and the local justice framework) to triangulation in order to converge on answers to four major policy questions: What is sustainable development? Why is it an issue? What needs to be done? What can actually be done? These four approaches are used to analyze the sustainable development controversy that recently arose in the pages of Science magazine and the journal Ecological Applications. These different approaches prove highly potent in defamiliarizing conventional wisdom about sustainable development. Ultimately the different approaches will converge on novel answers to the four questions. The practical implications of these conclusions are drawn out at the end of Taking Complexity Seriously in a detailed case study of ecosystem management.

Book Summary:

An extensive, accessible guide to the owls of Canada and the United States, featuring beautiful photography. There is no group of birds more mysterious and fascinating than owls. The loudmouths of the raptor world, they peep, trill, toot, bark, growl, shriek, whistle, chittle, whoop, chuckle, boom, and buzz. Indeed, very few actually “hoot.” They have become the stuff of lore and legend?from the Roman myth that an owl foot could reveal secrets, to the First Nations belief that an owl feather could give a newborn better night vision. But the truth about owls is much more exciting. In this book, natural history writer and wildlife photographer Wayne Lynch reveals the secrets of these elusive species with stunning photographs, personal anecdotes, and accessible science. The photos alone are masterpieces. Unlike most published owl photos, which are portraits of birds in captivity, the vast majority of these were taken in the wild?a product of the author-photographer’s incredible knowledge and patience. Lynch complements the photos with a wealth of facts about anatomy, habitat, diet, and family life. For each of the nineteen species that inhabit Canada and the United States, he provides a range map and a brief discussion of its distribution, population size, and status. Lynch debunks myths about owls’ “supernatural” powers of sight and hearing, discusses courtship rituals, and offers personal tips for finding owls in the wild. From the great horned to the tiny elf owl, this amazing volume captures the beauty and mystery of these charismatic birds of prey. Named one of the Best Reference Books of 2007 by Library Journal

A compelling argument that the time has come to use what we know about the fascinating and diverse inner lives of other animals on their behalf Every day we are learning new and surprising facts about just how intelligent and emotional animals are—did you know rats like to play and laugh, and also display empathy, and the ears and noses of cows tell us how they’re feeling? At times, we humans translate that knowledge into compassion for other animals; think of the public outcry against the fates of Cecil the lion or the captive gorilla Harambe. But on the whole, our growing understanding of what animals feel is not resulting in more respectful treatment of them. Renowned animal-behavior expert Marc Bekoff and leading bioethicist Jessica Pierce explore the real-world experiences of five categories of animals, beginning with those who suffer the greatest deprivations of freedoms and choice—chickens, pigs, and cows in industrial food systems—as well as animals used in testing and research, including mice, rats, cats, dogs, and chimpanzees. Next, Bekoff and Pierce consider animals for whom losses of freedoms are more ambiguous and controversial, namely, individuals held in zoos and aquaria and those kept as companions. Finally, they reveal the unexpected ways in which the freedoms of animals in the wild are constrained by human activities and argue for a more compassionate approach to conservation. In each case, scientific studies combine with stories of individual animals to bring readers face-to-face with the wonder of our fellow beings, as well as the suffering they endure and the major paradigm shift that is needed to truly ensure their well-being. The Animals’ Agenda will educate and inspire people to rethink how we affect other animals, and how we can evolve toward more peaceful and less violent ways of interacting with our animal kin in an increasingly human-dominated world.

Book Summary:

The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions Explores the conservation vs. public controversy issues around megafires in a rapidly warming world

Book Summary:

Human impact on natural landscapes through urbanization and agricultural expansion are becoming more and more dramatic and are the cause of serious environmental problems. This volume examines the effect of landscape disturbance on plant and animal diversity in the five mediterranean-climate regions of the world. It begins with three introductory chapters broadly reviewing the issues of landscape degradation. Further contributions describe regional land use conflicts in each of the five regions. Landscape disturbance and plant diversity, and landscape disturbance and animal diversity are treated in separate chapters. Four contributions deal with demography and ecophysiology in vegetation succession following disturbance. The volume closes with a consideration of the future addressing aspects of environmental politics.

Book Summary:

In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.

Book Summary:

Nature’s Burdens is a political and intellectual history of American natural resource conservation from the 1980s into the twenty-first century—a period of intense political turmoil, shifting priorities among federal policymakers, and changing ideas about the goals of conservation. Telling a story of persistent activism, conflict, and frustration but also of striking achievement, it is an account of how new ideas and policies regarding human relationships to plants, animals, and their surroundings have become vital features of modern environmentalism. In the 1960s and 1970s, Congress embraced the largely dormant movement to preserve distinctive landscapes and the growing demand for outdoor recreation, establishing an unprecedented number of parks, monuments, and recreation areas. The election of Ronald Reagan and a shift to a Republican-controlled Senate brought this activity to an abrupt halt and introduced a period of intense partisanship and legislative gridlock that extends to the present. In this political climate, three developments largely defined the role of conservation in contemporary society: environmental organizations have struggled to defend the legal status quo, private land conservation has become increasingly important, and the emergence of potent scientific voices has promoted the protection of animals and plants and injected a new sense of urgency into the larger cause. These developments mark this period as a distinctive and important chapter in the history of American conservation. Scrupulously researched, scientifically and politically well informed, concise, and accessibly written, Nature’s Burdens is the most comprehensive examination of recent efforts to protect and enhance the natural world. It will be of interest to environmental historians, environmental activists, and any general reader interested in conservation.
