Savannas are ecosytems with a continuous grass layer and scattered trees or shrubs. These lands occupy nearly a third of the earth’s land surface and are an important resource not only in world economies but also as repositories of biodiversity. Because savannas are generally thought of as tropical ecosystems, most reviews of the literature have tended to disregard savannas found in temperate zones. Yet these ecosystems are both extensive and diverse in North America, ranging from longleaf pine habitats along the Atlantic coastal plain to xeric piñon-juniper communities of the Great Basin-ecosystems seemingly disparate, yet similar enough to merit study as savannas. This book provides an overview of the patterns and processes shared by these ecosystems and offers substantive ideas regarding future management and research efforts. It describes the composition geographic distribution, climate, soils, and uses of savannas throughout North America, summarizing and integrating a wide array of literature. While discussing these ecological patterns and processes. McPherson develops a framework for implementing management practices and safeguarding the future of these important wildland ecosystems. Ecology and Management of North American Savannas takes a major step toward establishing the science of savanna ecology for North America. It encourages constructive debate and relevant research on these important systems and will also serve as a useful resource in biogeography, plant ecology, and rangeland management.
Fire, both inevitable and ubiquitous, plays a crucial role in North American ecosystems. But as necessary as fire is to maintaining healthy ecosystems, it threatens human lives and livelihoods in unacceptable ways. This volume explores the rich yet largely uncharted terrain at the intersection of fire policy, fire science, and fire management in order to find better ways of addressing this pressing dilemma. Written in clear language, it will help scientists, policy makers, and the general public, especially residents of fire-prone areas, better understand where we are today in regard to coping with wildfires, how we got here, and where we need to go. Drawing on abundant historical and analytic information to shed new light on current controversies, Living with Fire offers a dynamic new paradigm for coping with fire that recognizes its critical environmental role. The book also tells how we can rebuild the important ecological and political processes that are necessary for finding better ways to cope with fire and with other complex policy dilemmas.
The science of ecology and the practice of resource management are critical to our understanding of the Earth's ecosystems and our efforts to conserve them. This book attempts to bridge the gap between ecology and natural resource management and in particular, focuses on the discipline of plant ecology as a foundation for vegetation and wildlife management. It describes how concepts and approaches used by ecologists to study communities and ecosystems can be applied to their management. Guy R. McPherson and Stephen DeStefano emphasise the importance of thoughtfully designed and carefully conducted scientific studies to both the advancement of ecological knowledge and the application of techniques for the management of plant and animal populations. The book is aimed at natural resource managers, as well as graduate and advanced undergraduate students, who are familiar with fundamental ecological principles and who want to use ecological knowledge as a basis for the management of ecosystems.
We are the last individuals of our species on Earth. How shall we respond? How shall we act? If industrial civilization is maintained, climate change will cause human extinction in the near term. If industrial civilization falls, sufficient ionizing radiation will be released from the world's nuclear power plants to cause human extinction in the near term. In the wake of this horrific conclusion, conservation biologist Guy McPherson proposes we act with compassion, courage, and creativity. He suggests we act with the kind of empathy for which humans are renowned. In other words, he suggests we act with decency toward the humans and other organisms with which we share this beautiful planet. Going Dark is the story of one scientist's response to the horrors we face. It is a deeply personal narrative infused with abundant evidence to support its terrifying claims. In the words of syndicated cartoonist David Fitzsimmons, McPherson's "approach is disarming and his message is both life-changing and convincingly alarming. A blend of Paul Revere with Rachel Carson, Guy McPherson is a significant voice of rational conscience nudging in the wilderness. Fierce as Ed Abbey, and equally prophetic, Professor McPherson is a modern-day John Muir with a global perspective. Beyond the warnings is a body of thoughtful and pragmatic real world ideas.
Ms. Ladybug and Mr. Honeybee: A Love Story at the End of Time tells the story of a ladybug and a honeybee who find each other after losing their entire families to the poisonous fogs the humans are spraying. The unlikely duo pursues a safe haven from the poisonous fog and are aided by lightning bugs, a mysterious dragonfly, and even cockroaches along the adventure of a lifetime. They encounter doubting ticks, denying termites, and a slug desperately resigned to his fate along their way, but they never give up in their seemingly hopeless quest.
