Available in PDF, EPUB and Kindle. Book excerpt: As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: The processes and mechanisms that control the growth of woody plants are of crucial importance for both economic and biological reasons. The comprehensive coverage of Growth Control in Woody Plants includes discussion of the growth controlling factors in both reproductive structures (flowers, fruit, seeds, pollen, etc.) and vegetative organs (stems, branches, leaves, and roots). Other major topics covered include seed germination, seedling growth, physiological and environmental regulation of growth, cultural practices, and biotechnology.This comprehensive treatment of the many factors that control the growth of woody plants can serve both as a valuable text and as a frequently used reference.* Includes comprehensive representation of a broad subject* Provides thorough bibliographic coverage * Well illustrated* Serves as a vital companion to Physiology of Woody Plants, Second Edition

Book excerpt: NATIONAL BESTSELLER • WINNER OF THE GOVERNOR GENERAL'S LITERARY AWARD FOR NON-FICTION • WINNER OF THE WRITERS’ TRUST NON-FICTION PRIZE “Absolutely spellbinding.” —The New York Times The environmental true-crime story of a glorious natural wonder, the man who destroyed it, and the fascinating, troubling context in which this act took place. FEATURING A NEW AFTERWORD BY THE AUTHOR On a winter night in 1997, a British Columbia timber scout named Grant Hadwin committed an act of shocking violence in the mythic Queen Charlotte Islands. His victim was legendary: a unique 300-year-old Sitka spruce tree, fifty metres tall and covered with luminous golden needles. In a bizarre environmental protest, Hadwin attacked the tree with a chainsaw. Two days later, it fell, horrifying an entire community. Not only was the golden spruce a scientific marvel and a tourist attraction, it was sacred to the Haida people and beloved by local loggers. Shortly after confessing to the crime, Hadwin disappeared under suspicious circumstances and is missing to this day. As John Vaillant deftly braids together the strands of this thrilling mystery, he brings to life the ancient beauty of the coastal wilderness, the historical collision of Europeans and the Haida, and the harrowing world of logging—the most dangerous land-based job in North America.

Download or read book Ecology in Agriculture written by Louise E. Jackson and published by Academic Press. This book was released on 1997-09-14 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural crops are prominent features of an increasing number of variously perturbed ecosystems and the landscapes occupied by these ecosystems. Yet the ecology of agricultural-dominated landscapes is only now receiving the scientific attention it has long deserved. This attention has been stimulated by the realization that all agriculture must become sustainable year after year while leaving nearby ecosystems unaffected. Ecology in Agriculture focuses exclusively on the ecology of agricultural ecosystems. The book is divided into four major sections. An introduction establishes the unique ties between agricultural and ecological sciences. The second section describes the community ecology of these sorts of ecosystems, while the final section focuses on the processes that operate throughout these agricultural landscapes. - Contains an ecological perspective on agricultural production and resource utilization - Includes in-depth reviews of major issues in crop ecology by active researchers - Covers a range of topics in agricultural ecophysiology, community ecology, and ecosystems ecology - Provides examples of ecological approaches to solving problems in crop management and environmental quality

Download or read book Guide to U S Economic Policy written by Robert E. Wright and published by CQ Press. This book was released on 2014-06-30 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guide to U.S. Economic Policy shows students and researchers how issues and actions are translated into public policies for resolving economic problems (like the Great Recession) or managing economic conflict (like the left-right ideological split over the role of government regulation in markets). Taking an interdisciplinary approach, the guide highlights decision-making cycles requiring the cooperation of government, business, and an informed citizenry to achieve a comprehensive approach to a successful, growth-oriented economic policy. Through 30 topical, operational, and relational essays, the book addresses the development of U.S. economic policies from the colonial period to today; the federal agencies and public and private organizations that influence and administer economic policies; the challenges of balancing economic development with environmental and social goals; and the role of the U.S. in international organizations such as the IMF and WTO. Key Features: 30 essays by experts in the field investigate the fundamental economic, political, social, and process initiatives that drive policy decisions affecting the nation’s economic stability and success. Essential themes traced throughout the chapters include scarcity, wealth creation, theories of economic growth and macroeconomic management, controlling inflation and unemployment, poverty, the role of government agencies and regulations to police markets, Congress vs. the president, investment policies, economic indicators, the balance of trade, and the immediate and long-term costs associated with economic policy alternatives. A glossary of key economic terms and events, a summary of bureaus and agencies charged with economic policy decisions, a master bibliography, and a thorough index appear at the back of the book. This must-have reference for students and researchers is suitable for academic, public, high school, government, and professional libraries.
