Book Description
Wildfires kill many animals, but are populations of animals affected? How do animals survive the passage of fire? Why do some tree species survive and others die in a fire? Do frequent fires cause changes in plant community composition? Answering questions such as these requires an understanding of the ecological effects of fire. Aimed at senior undergraduate students, researchers, foresters and other land managers, Dr Whelan's book examines the changes wrought by fires with reference to general ecological theory. The impacts of fires on individual organisms, populations and communities are examined separately, and emphasis is placed on the importance of fire regime. Each chapter includes a listing of 'outstanding questions' that identify gaps in current knowledge. The book finishes by summarising the major aspects of ecology that are of particular relevance to management of fires - both protection against wildfires and deliberate use of fire.

Book Description
Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. Leading international contributors have been recruited by the editors to prepare a didactic text/reference that will appeal to both advanced students and practicing professionals.

Book Description
Global warming is expected to change fire regimes, likely increasing the severity and extent of wildfires in many ecosystems around the world. What will be the landscape-scale effects of these altered fire regimes? Within what theoretical contexts can we accurately assess these effects? We explore the possible effects of altered fire regimes on landscape patch dynamics, dominant species (tree, shrub, or herbaceous) and succession, sensitive and invasive plant and animal species and communities, and ecosystem function. Ultimately, we must consider the human dimension: what are the policy and management implications of increased fire disturbance, and what are the implications for human communities?

Book Description
The devastating fire that swept through Los Alamos, New Mexico, in the spring of 2000 may have been caused by one controlled burn gone wild, but it was far from an isolated event. All through the twentieth century, our national forests have been under assault from all sides: first ranchers and loggers laid their claims to our national forests, then recreationists and environmentalists spoke up for their interests. Who are our national forests really for? In this book, leading environmental historians show us what has been happening to these fragile woodlands. Taking us from lumber towns to Indian reservations to grazing lands, Forests under Fire reveals the interaction of Anglos, Hispanics, and Native Americans with the forests of the American Southwest. It examines recent controversies ranging from red squirrel conservation on Mt. Graham to increased tourism in our national forests. These case studies offer insights into human-forest relationships in places such as the Coconino National Forest, the Vallecitos Sustained Yield Unit, and the Gila Wilderness Area while also drawing on issues and concerns about similar biospheres in other parts of the West. Over the past century, forest management has evolved from a field dominated by the "conservationist" perspective—with humans exploiting natural resources-to one that emphasizes biocentrism, in which forests are seen as dynamic ecosystems. Yet despite this progressive shift, the assault on our forests continues through overgrazing of rangelands, lumbering, eroding mountainsides, fire suppression, and threats to the habitats of endangered species. Forests under Fire takes a closer look at the people calling the shots in our national forests, from advocates of timber harvesting to champions of ecosystem management, and calls for a reassessment of our priorities—before our forests are gone.

Book Description
A critical look into how and why the U.S. military needs to become more adaptable. Every military must prepare for future wars despite not really knowing the shape such wars will ultimately take. As former U.S. Secretary of Defense Robert Gates once noted: "We have a perfect record in predicting the next war. We have never once gotten it right." In the face of such great uncertainty, militaries must be able to adapt rapidly in order to win. Adaptation under Fire identifies the characteristics that make militaries more adaptable, illustrated through historical examples and the recent wars in Iraq and Afghanistan. Authors David Barno and Nora Bensahel argue that militaries facing unknown future conflicts must nevertheless make choices about the type of doctrine that their units will use, the weapons and equipment they will purchase, and the kind of leaders they will select and develop to guide the force to victory. Yet after a war begins, many of these choices will prove flawed in the unpredictable crucible of the battlefield. For a U.S. military facing diverse global threats, its ability to adapt quickly and effectively to those unforeseen circumstances may spell the difference between victory and defeat. Barno and Bensahel start by providing a framework for understanding adaptation and include historical cases of success and failure. Next, they examine U.S. military adaptation during the nation's recent wars, and explain why certain forms of adaptation have proven problematic. In the final section, Barno and Bensahel conclude that the U.S. military must become much more adaptable in order to address the fast-changing security challenges of the future, and they offer recommendations on how to do so before it is too late.

Book Description
This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.

Book Description
"A must-read ecological message of hope . . . Everyone with an interest in the future of this planet should read this book." --David Mitchell, The Guardian When climate activist Greta Thunberg was eleven, her parents Malena and Svante, and her little sister Beata, were facing a crisis in their own home. Greta had stopped eating and speaking, and her mother and father had reconfigured their lives to care for her. Desperate and searching for answers, her parents discovered what was at the heart of Greta’s distress: her imperiled future on a rapidly heating planet. Steered by Greta’s determination to understand the truth and generate change, they began to see the deep connections between their own suffering and the planet’s. Written by a remarkable family and told through the voice of an iconoclastic mother, Our House Is on Fire is the story of how they fought their problems at home by taking global action. And it is the story of how Greta decided to go on strike from school, igniting a worldwide rebellion.
