Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
"This book is a remarkably personal report of the authors’ trans-tropical experiences with forest dwellers. The experience was extensive, sometimes spanning years, and the report is the work of professional reporters, experienced at reaching to the core of critical issues of life and survival. The story is not a pretty one, and the prognosis is not good. But in their eyes the key lies in restoring and defending the rights of forest dwellers and encouraging in every way their age-old interest in preserving the integrity of forest lands. The authors are familiar with the international agencies and their programs, their successes and failures. Roger Stone was intimately involved in the World Commission on Forests and Sustainable Development and draws heavily on that experience. The book will strengthen the conclusions of that Commission to the effect that the world’s future lies heavily entangled with the continuity of forests globally, and that continuity hinges on respect for local interests."—George M. Woodwell, Director, Woods Hole Research Center "For twenty years, we have watched TV specials on the destruction of tropical forests -- an acre a second lost, every second for twenty years. This beautifully written book takes you right to the middle of the current international debate about what to do about it. It pulls no punches and proposes its own provocative solution. It offers a perspective that cannot be ignored and an answer that needs to be tried."—James Gustave Speth, Yale School of Forestry and Environmental Science "For more than a century, the conservation movement has dedicated its energy to protecting the Earth’s biodiversity. WWF has built its conservation philosophy and foundation for over forty years on principles of sound science, effective public policy, and recognition of the fundamental role local people bring to achieving tangible conservation results on the ground. Roger Stone and Claudia D’Andrea take us on a tour of the tropical forested regions of the world and capture important lessons about the merits of local control over forest resources. Their wide-ranging portrayal of community-based forest management arrangements, set within the global context of deforestation and loss of biodiversity, provides compelling testimony to the wisdom of empowering local people and nurturing their spirit as effective forest stewards."—Kathryn S. Fuller, President, World Wildlife Fund

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Description
These memoirs trace the wild and adventurous life of Pérez Rosales from his childhood up to the 1860s. During that approximately half-century he saw and did more than a dozen ordinary men. At age eleven in Argentina he witnessed the executions of Luis and Juan Jose Carrera. From there, his activities and adventures took him on several journeys on sailing vessels around Cape Horn; to Paris, where he witnessed the July revolution of 1830; to various commercial endeavors including a distillery, the practice of medicine, and cattle smuggling; into service as an advisor to an Argentine warlord; as a miner for precious metals in the north of Chile; as participant in the California Gold Rush in 1849; as director of the government's project for German immigration and settlement in the wild south of Chile; and also as Chilean consul and immigration agent in Hamburg. Around the world, Rosales lived through many of his era's watershed moments. His exciting memoirs offer a chance to relive the rush and chaos of these times--from a much safer vantage.

Book Description
When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.
