This book documents historically fruitful ecological collaborations in the early years of studying large ecosystems in the United States. As the book explains, the concept of the ecosystem—a local biological community and its interactions with its environment—has given rise to many institutions and research programs, like the National Science Foundation's program for Long Term Ecological Research. This book's insider account of this important and fascinating trend toward big science takes us from the paradigm of collaborative interdisciplinary research, starting with the International Geophysical Year (IGY) of 1957, through the International Biological Program (IBP) of the late 1960s and early 1970s, to the Long-Term Ecological Research (LTER) programs of the 1980s.

The largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. This review takes the reader from Darwin's early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The chapters furnish a discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change.

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. This analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the chapters find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal—conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy for maintaining both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.

The San Francisco Bay, the biggest estuary on the west coast of North America, was once surrounded by an almost unbroken chain of tidal wetlands, a fecund sieve of ecosystems connecting the land and the Bay. Today, most of these wetlands have disappeared under the demands of coastal development, and those that remain cling precariously to a drastically altered coastline. This volume is a collaborative effort of nearly 40 scholars in which the wealth of scientific knowledge available on tidal wetlands of the San Francisco Estuary is summarized and integrated. This book addresses issues of taxonomy, geomorphology, toxicology, the impact of climate change, ecosystem services, public policy, and conservation, and it is an essential resource for ecologists, environmental scientists, coastal policymakers, and researchers interested in estuaries and conserving and restoring coastal wetlands around the world.

Fires are both an integral natural process in the California landscape and growing threat to its urban and suburban developments as they encroach on wildlands. This book synthesizes knowledge of the science, ecology, and management of fire in California. Part I introduces the basics of fire ecology. It includes an historical overview of fire, vegetation, and climate in California; overviews of fire as a physical and ecological process; and reviews the interactions between fire and the physical, plant, and animal components of the environment. Part II explores the history and ecology of fire in each of California’s nine bioregions. Part III examines fire management in California, including both Native American and post-European settlement; discusses current issues related to fire policy and management, including air quality, watershed management, invasive plant species, native species, and fuel management; and considers the future of fire management.

Part autobiography, part philosophical rumination, this conservation odyssey explores the deep affinities between humans and our original habitat: grasslands. The book traces the evolutionary, historical, and cultural forces that have reshaped North American rangelands over the past two centuries. It introduces an intriguing cast of characters—wildlife and grasslands biologists, archaeologists, ranchers, and petroleum geologists—to illuminate a wide range of related topics: our love affair with turf and how it manifests in lawns and sports, the ecological and economic dimensions of ranching, the glory of cowboy culture, grasslands and restoration ecology, and more. This book ultimately provides the background against which we can envision a new paradigm for restoring rangeland ecosystems—and a new paradigm for envisioning a more sustainable future.

Guana, in the British Virgin Islands, is home to a remarkably diverse assortment of animal and plant life: mangroves, flamingos, iguanas, frogs, birds, snakes, spiders, tortoises, grasshoppers, and bats, to name but a few. What is so surprising about Guana's astonishing panoply is that, according to prevailing ecological theories, the island's diversity should be much lower than it actually is. This book describes Guana's flora and fauna against the backdrop of islands worldwide and their ecology, evolution, and conservation. Much more than a book about one island, it raises important challenges to prevailing dogma of island biogeography and theoretical ecology. The author demonstrates that meaningful conservation and avoiding tragic loss of biodiversity demand we know far more about biological interactions, physiographic and geological structure, meteorology, and other factors. He presents compelling evidence that high levels of natural biodiversity underpin ecosystem resilience and stability. The narrative, containing many asides and personal reflections, widens into a commentary about the nature of life on earth.

Physics and chemistry are distinguished from biology by the way generalizations are codified into theories tested by observation and experimentation. Some theories have been sufficiently tested to qualify as laws. In ecology, generalizations worthy of being called theories are less common because observations and experimentation are difficult and exceptions are more common. This book enumerates generalizations in ecology. Introductory material describes how the practice of science in general, and ecology specifically, yields theories and laws. The text also discusses why such ideas are only useful if they have predictive ability, and delineates the scope of these generalizations and the constraints that limit their application.

Fire, both inevitable and ubiquitous, plays a crucial role in North American ecosystems. But as necessary as fire is to maintaining healthy ecosystems, it threatens human lives and livelihoods in unacceptable ways. This volume explores the rich yet largely uncharted terrain at the intersection of fire policy, fire science, and fire management in order to find better ways of addressing this pressing dilemma. This book aims to help scientists, policy makers, and the general public, especially residents of fire-prone areas, better understand where we are today in regard to coping with wildfires, how we got here, and where we need to go. Drawing on abundant historical and analytic information to shed new light on current controversies, this book offers a dynamic new paradigm for coping with fire that recognizes its critical environmental role. The book also tells how we can rebuild the important ecological and political processes that are necessary for finding better ways to cope with fire and with other complex policy dilemmas.

Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. Mercury in the Environment follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.
