The forest of the northwest coast of North America accounts for two thirds of the world's temperate-zone rain forest, which is a fraction of the size of the more publicized tropical rain forest but is currently being lost at a comparable rate. Coming at a time of public concern and controversy regarding the future of the forest, this book provides a fresh examination of the natural dynamics that have produced the remarkably lush growth characterizing roughly two thousand miles of coast from Coos Bay, Oregon, to the gulf of Alaska--a stretch of greater north-south ecological sameness than exists anywhere else on earth. The rain forest valleys of Washington's Olympic Peninsula stand out as the showpiece of this region. Because the forest's productivity and sheer biomass per square mile are among the world's greatest, it is recognized as a National Park, a World Biosphere Reserve, and a World Heritage Site. Pointing out that ecology and economics share the same root (oikos, meaning ?home?), this book evokes the forest's beauty and intricacy while summarizing scientific understanding of components and interactions. We learn that moldering logs produce their own moisture as a by-product of decay, and are virtual reservoirs as well as storehouses of nutrients--qualities that contribute to their role as the rain forest's famed nurse logs, which act as seedbeds for oncoming generations of spruce and hemlock. We also learn that fallen trees affect stream flow and crucially influence the well-being of aquatic organisms (including fish) and that, washed downriver, they modify both beach character and life in the ocean near river mouths. The unique ecological web of this ancient forest--which has existed for at least five thousand years--includes the peculiar above-ground rooting of maple trees, which actually feed from the mossy ?upholstery? covering their trunks and branches; the role of elk as ?landscape gardners? preventing the understory from becoming a thicket; and a newly discovered life community within the gravel zone of river bottoms and out under the forest floor. ?Many of the spruce and hemlock trees we walk among today were alive when men like Sir Francis Bacon and Johannes Kepler first recognized the value of objective data over mystical portents,? write authors Ruth Kirk and Jerry Franklin. ?They have been pushing their roots through the soil and wafting seeds into the air throughout the entire existence of science.' This book will be welcomed by resident Northwesterners and travelers as well as by all who are interested in nature. Its prose is both broadly readable and scientifically sound. More than 100 color photographs catch the variety and grandeur of this magnificent forest.

The Ecology of Seashores explores the complex shore environment. It covers the ways in which representative species have adapted to life in a constantly changing environment in terms of their interactions, the control of community structure, and how energy and materials are cycled in different ecosystems. Written by an eminent marine biologist, this work emphasizes ecological processes and the use of systems analysis in understanding such processes. He gives complete coverage of the ecology of all seashore types: rocky shores, soft shores, sandy beaches, and estuaries at an advanced level. When appropriate, the author uses the energy circuit language of symbols and diagrams developed by H.T. Odum as a basis of understanding. The first comprehensive review and synthesis of the research on shore ecosystems, the book lends order to some of the most complex ecosystem types and presents a wide range of geographical examples. If you are involved in researching or managing coastal zones, The Ecology of Seashores provides exhaustive coverage of the essential background information you need.

From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, that has not been the case. Instead, we have managed this dichotomy by compartmentalizing the American landscape. Congress and my predecessors handled resource conflicts by drawing enclosures: "We'll create a national park here," they said, "and we'll put a wildlife refuge over there." Simple enough, as far as protection goes. And outside those protected areas, the message was equally simplistic: "Y'all come and get it. Have at it." The nature and the pace of the resource extraction was not at issue; if you could find it, it was yours.

A New Ecology presents an ecosystem theory based on the following ecosystem properties: physical openness, ontic openness, directionality, connectivity, a complex dynamic for growth and development, and a complex dynamic response to disturbances. Each of these properties is developed in detail to show that these basic and characteristic properties can be applied to explain a wide spectrum of ecological obsevations and convections. It is also shown that the properties have application for environmental management and for assessment of ecosystem health. * Demonstrates an ecosystem theory that can be applied to explain ecological observations and rules * Presents an ecosystem theory based upon a systems approach * Discusses an ecosystem theory that is based on a few basic properties that are characteristic for ecosystmes

Food webs are one of the most useful, and challenging, objects of study in ecology. These networks of predator-prey interactions, conjured in Darwin's image of a "tangled bank," provide a paradigmatic example of complex adaptive systems. This book is based on a February 2004 Santa Fe Institute workshop. Its authors treat the ecology of predator-prey interactions, food web theory, structure and dynamics. The book explores the boundaries of what is known of the relationship between structure and dynamics in ecological networks and will define directions for future developments in this field.

Process thought is the foundation for studies in many areas of contemporary philosophy, theology, political theory, educational theory, and the religion-science dialogue. It is derived from Alfred North Whitehead's philosophy, known as process theology, which lays a groundwork for integrating evolutionary biology, physics, philosophy of mind, theology, environmental ethics, religious pluralism, education, economics, and more. In Process-Relational Philosophy, C. Robert Mesle breaks down Whitehead's complex writings, providing a simple but accurate introduction to the vision that underlies much of contemporary process philosophy and theology. In doing so, he points to a "way beyond both reductive materialism and the traps of Cartesian dualism by showing reality as a relational process in which minds arise from bodies, in which freedom and creativity are foundational to process, in which the relational power of persuasion is more basic than the unilateral power of coercion." Because process-relational philosophy addresses the deep intuitions of a relational world basic to environmental and global thinking, it is being incorporated into undergraduate and graduate courses in philosophy, educational theory and practice, environmental ethics, and science and values, among others. Process-Relational Philosophy: A Basic Introduction makes Whitehead's creative vision accessible to all students and general readers.

Across the continental United States, one can identify 20 distinct forest cover types. Most of these are to be found on federal lands managed by the U.S. Forest Service and Bureau of Land Management. Those responsible for the management of trees that form the 20 different cover types and the diversity of forest wildlife that reside in them must have a solid grounding in concepts of forest management, especially silviculture, as well as concepts of wildlife management, in order to integrate both as part of any effective natural resource management plan. Forest Wildlife Ecology and Habitat Management provides both foresters and wildlife biologists responsible for managing forest resources with an integrated understanding of the relationship between forests and wildlife. Based on David Patton’s 50 years of experience as a forester and wildlife biologist, the book shows readers how to look at forests as ecological systems and wildlife as part of the energy flow and nutrient cycling process within those systems. He offers readers a fundamental understanding of the natural processes that occur in a forest taking into consideration vegetation, water, and the natural effects of climate and time. He then provides a biological perspective on wildlife, discussing reproduction, behavior, feeding habits, and mobility. He also discusses the various influences on forests and wildlife by both natural and human-caused events. Covering those forest types included in the U.S. National Atlas, and associating over 1,100 wildlife species with 20 major forest types in 48 states, Professor Patton provides recommendations for ways to restore and maintain wildlife habitat by direct and indirect coordination. Towards this end, the author — Evaluates various approaches to integrate forestry and wildlife management Offers a number of practical management strategies, emphasizing a progressive holistic approach Presents the FAAWN (Forest Attributes and Wildlife Needs) data model A CD-ROM is included that provides readers with easy-to-use software that will help them consider more than 63,000 potential associations among forest components and wildlife within the FAAWN model.

Communities of microscopic plant life, or phytoplankton, dominate the Earth's aquatic ecosystems. This important new book by Colin Reynolds covers the adaptations, physiology and population dynamics of phytoplankton communities in lakes and rivers and oceans. It provides basic information on composition, morphology and physiology of the main phyletic groups represented in marine and freshwater systems and in addition reviews recent advances in community ecology, developing an appreciation of assembly processes, co-existence and competition, disturbance and diversity. Although focussed on one group of organisms, the book develops many concepts relevant to ecology in the broadest sense, and as such will appeal to graduate students and researchers in ecology, limnology and oceanography.
