Forests are restless. When a tree dies or a new one sprouts, the forest that includes it shifts. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles-humans felling trees by the billions, invasive pests transported through global trade-threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before and forests are struggling to keep up. A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya and Monterey pine. Zach St George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand and new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St George meets lively people on conservation's front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists and foresters, each with their own role to play in the fight for the uncertain future of our environment. An eye-opening investigation into forest migration past and present, The Journeys of Trees examines how we can all help our trees, and our planet, survive and thrive.
Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation, urbanization, and land clearing through deforestation and brush fires. In order to conserve biodiversity in plants, it is important to targets three independent levels that include ecosystems, species and genes. Genetic diversity is important to a species' fitness, long-term viability, and ability to adapt to changing environmental conditions. Chapters in this book are written by leading geneticists, molecular biologists and other specialists on relevant topics on genetic erosion and conservation genetic diversity in plants. This divisible set of two volumes deals with a broad spectrum of topics on genetic erosion, and approaches to biodiversity conservation in crop plants and trees. Volume 1 deals with indicators and prevention of genetic erosion, while volume 2 covers genetic diversity and erosion in a number of plants species. These two volumes will also be useful to botanists, biotechnologists, environmentalists, policy makers, conservationists, and NGOs working to manage genetic erosion and biodiversity.
Coast lines have been and still are the centre lines of civilization around the world with still increasing pressure from both sides, the hinterland and the sea, with all its foreseeable and unforeseeable impacts given by nature or mankind. While response of nature to such impacts is flexible in the way that all morphological changes with all the consequences are tolerated as part of the system, man cannot tolerate short-term or long-term changes without being threatened in its physical and economical existence. The objectives of this Advanced Research Workshop (ARW) on Environmentally Friendly Coastal Structures were: - to contribute to the critical assessment of existing knowledge in the field of coastal and environmental protection; - to identify directions for future research in that area; - to promote close working relationships between scientists from different countries and with different professional experience. Latest trends in research in coastal and environmental protection have been summarized and developed during the meeting. Seventeen papers are presented in this book, attempting to cover as completely as possible all related aspects a" coast, engineering structures, water, sediments, ecosystems in their complicated interaction.
A compelling look at the challenges of freshwater conservation and management issues facing the United States at the start of the new millennium. Battles have been fought, lives have been lost, countries divided-and all for one reason-water. Freshwater Issues provides a quick education in the basics and essential issues of freshwater management. From water supply and resource information to the role of water in ecosystems, the coverage also provides global water data, examines uncertainties about future water supplies, and addresses technological advances in the development of water resources and environmental safeguards. Thorough treatment is given to water rights, allocation issues, and U.S. water laws and their many regional variations. This is followed by an explanation of the economics of water, from ownership and pricing to social impact and discussions of often-conflicting public, environmental, and private interests. The war over water has just begun.
This book addresses issues related to sources of groundwater pollution such as arsenic, uranium, fluoride and their effects on human health. It discusses extensively the removal of heavy metals, arsenic and fluoride from drinking water. Bioremediation and phyto remediation on biomass productivity are treated in several chapters in the book. The volume highlights leachate characteristics analysed both in the laboratory and in field studies assessing the trace metals in rainwater. This book is a study on the judicious management of natural resources and exposes environmental problems particularly those related to pollution and bioremediation.
This book presents new concepts as well as practical applications and experiences in the field of information technology for environmental engineering. The book has three main focus areas: firstly, it shows how information technologies can be employed to support natural resource management and conservation, environmental engineering, scientific simulation and integrated assessment studies. Secondly, it demonstrates the application of computing in the everyday practices of environmental engineers, natural scientists, economists and social scientists. And thirdly, it demonstrates how the complexity of natural phenomena can be approached using interdisciplinary methods, where computer science offers the infrastructure needed for environmental data collection and management, scientific simulations, decision support documentation and reporting.The book collects selected papers presented at the 7th International Symposium on Environmental Engineering, held in Port Elizabeth, South Africa in July 2015. It discusses recent success stories in eco-informatics, promising ideas and new challenges from the interdisciplinary viewpoints of computer scientists, environmental engineers, economists and social scientists, demonstrating new paradigms for problem-solving and decision-making.
New edition of a NOLS classic; the definitive book on environmental ethics and their relation to managing wildlands An excellent introduction to all relevant federal agencies and legislation Objectively examines various perspectives on difficult ethical questions Originally published in 1992 as "An Introduction to Wildland Ethics and Management," this fully revised and updated edition is a powerful tool for understanding the challenges facing wilderness in the United States today. Beginning with the premise that land management must be informed by a well-developed wilderness ethic, the authors delve into some of the thorniest problems in environmental ethics, exploring them in clear, straightforward language: What is wilderness? Why should it be protected? Do animals have rights? Do trees? When should wilderness concerns trump individual priorities? The book also provides a fascinating history of the wilderness movement in America and gives a comprehensive survey of the legislation and agency structures that define wildlands management today. Essential reading for land managers, activists, policymakers, or anyone else who cares about the future of wilderness in the United States.
Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as a cause of species loss. In particular, there is little information about the ecological impacts of hyper-diverse groups such as terrestrial fungi and invertebrates. A science symposium, Ecological impacts of non-native invertebrates and fungi on terrestrial ecosystems, held in 2006, brought together scientists from the USA and Canada to review the state of knowledge in this field of work. Additional reviews were solicited following the symposium. The resulting set of review/synthesis papers and case studies represents a cross-section of work on ecological impacts of non-native terrestrial invertebrates and fungi. Although there is a strong focus on Canadian work, there is also significant presentation of work in the northern USA and Europe.
Part travelogue, part history, and part environmental treatise, "Mekong - The Occluding River" is above all else an urgent warning that factors such as pollution, ecological devastation, and the depletion of natural resources are threatening the very existence of the Mekong River. Author Ngo The Vinh combines his vivid travel notes and collection of photographs with a meticulously researched history of the environmental degradation of the Mekong River. Translated from Vietnamese, the best-selling treatise outlines the myriad threats facing the river today. From oil shipments feeding the industrial cities of southwestern China to gigantic hydroelectric dams known as the Mekong Cascades in Yunnan province, China is the worst environmental offender, though the other nations along Mekong's banks behave no better. From Thailand to Laos to Vietnam, hydroelectric dams that threaten the Mekong and its inhabitants are being built at an alarming rate. To save the Mekong, Ngo The Vinh calls upon all the nations that benefit from its life-giving water to observe the "Spirit of the Mekong" in the implementation of all future development projects. To achieve this end, there must be a concerted and sustained commitment to cooperation and sustainability. At this critical cross-roads, we should remind ourselves of the mantra from Sea World San Diego: "Extinction is forever. Endangered means we still have time."
Grand Canyon For Sale is a carefully researched investigation of the precarious future of America's public lands: our national parks, forests, wildlife refuges, monuments, and wildernesses. Taking the Grand Canyon as his key example, and using on-the-ground reporting as well as scientific research, Stephen Nash shows how accelerating climate change will dislocate wildlife populations and vegetation across hundreds of thousands of square miles of the national landscape. In addition, a growing political movement, well financed and occasionally violent, is fighting to break up these federal lands and return them to state, local, and private control. That scheme would foreclose the future for many wild species, which are part of our irreplaceable natural heritage, and also would devastate our national parks, forests, and other public lands. To safeguard wildlife and their habitats, it is essential to consolidate protected areas and prioritize natural systems over mining, grazing, drilling, and logging. Grand Canyon For Sale provides an excellent overview of the physical and biological challenges facing public lands. The book also exposes and shows how to combat the political activity that threatens these places in the U.S. today.
Things have changed. In 1969 when the Convention for the Conservation of the Vicuna was drafted, in an attempt to save the vicuna from its tumbling decline towards extinction, both the science and the philosophy of wildlife conservation were radically different. It is thus a tribute to the prescience of those involved at the time that the rescue plan had, even through the harsh lens of hindsight, a d- tinctly Twenty First Century flavour. After all, it was predicated on the expectation that if vicuna could be saved, they would one day become a valued asset, generating revenue for the human communities that fostered their survival. Embodied in this aspiration are the main structures of modern biodiversity conservation - not only is it to be underpinned by science, but that science should be of both the natural and the social genres, woven into inter-disciplinarity, and thereby taking heed of e- nomics, governance, ownership and the like, alongside biology. In addition, it should include, as a major strut, the human dimension, taking account of the affected constituencies with their varied stakes in alternative outcomes. This c- temporary framework for thinking about biodiversity conservation is inseparable from such wider, and inherently political, notions as community-based conser- tion and ultimately sustainable use.
This book addresses the future of urbanisation on the Galapagos Islands from a systems, governance and design perspective with the competing parameters of liveability, economic and ecological, using the Galapagos as a laboratory for the theoretical and postulative understanding of evolving settlement and habitation. The Galapagos islands are one of the world's most examined and reported examples of a series of naturally evolving ecosystems. The biodiversity of these island ecosystems are the focus of tourism and the image across the world yet human settlement are part of the local ecology. While human intervention is limited, the islands are a distinctive context in which to consider the impact of human habitation as a part of our ecosystems. In this book, authors take the framework of complex adaptive systems (CAS) in which to model systems that grow and evolve, the relations between these various sectors change; systems that get more complex as they evolve. Tested and applied discretely in the two realms of natural and urban, for the first time this text will bring the two together in understanding options for the future of urban settlements on the Galapagos Islands and, by extension, consider how the approach can be used globally in other contexts.
This updated guide provides the latest findings about the biology and ecology of the Gulf of Mexico. It reflects the effects of recent storms and hurricanes, and includes an expanded chapter on sea turtles. Hundreds of detailed drawings introduce you to more than 300 marine creatures commonly found along the beaches and bays of this area. Easy-to-read descriptions explain the taxonomic feeding, mating, and migratory habits of these coastal residents. In addition, this guide tells you about many offshore creatures, such as oysters, shrimp, and lobsters, and the numerous animals that inhabit the subsea oil platforms.
This book provides insight into the instances in which wildlife species can create problems. Some species trigger problems for human activities, but many others need humans to save them and to continue to exist. The text addresses issues faced by economists and politicians dealing with laws involving actions undertaken to resolve the problems of the interaction between humans and wildlife. Here, the words 'problematic species' are used in their broadest sense, as may be appreciated in the short introductions to the various sections. At times, the authors discuss special cases while always extending the discussion into a more general and broad vision. At others, they present real cutting-edge analysis of ecological topics and issues. The book will be of interest to biologists, ecologists and wildlife managers involved in research on wildlife, parks, and environmental management, as well as to government departments and agencies, NGOs and conservation wildlife organizations. Even those in contact with nature, such as hunters, herders, and farmers, will be able to find a great deal of important information. Specific case studies are selected from among the most significant and prevalent cases throughout the world. A total of 26 papers have been selected for this book, written by zoologists, biologists and ecologists. Many have an interdisciplinary approach, with contributions by economists, criminologists, technical specialists, and engineers.

Pollution, resource depletion, habitat management, and climate change are all issues that necessarily transcend national boundaries. Accordingly, they and other environmental concerns have been a particular focus for international organizations from before the First World War to the present day. This volume is the first to comprehensively explore the environmental activities of professional communities, NGOs, regional bodies, the United Nations, and other international organizations during the twentieth century. It follows their efforts to shape debates about environmental degradation, develop binding intergovernmental commitments, and-following the seminal 1972 Conference on the Human Environment-implement and enforce actual international policies. |
