A Neotropical Companion: An Introduction to the Animals, Plants, and Ecosystems of the New World Tropics (2nd Edition, Revised and Expanded)

by John Kricher

A Neotropical Companion is an extraordinarily readable introduction to the American tropics, the lands of Central and South America, their remarkable rainforests and other ecosystems, and the creatures that live there. It is the most comprehensive one-volume guide to the Neotropics available today. Widely praised in its first edition, it remains a book of unparalleled value to tourists, students, and scientists alike. This second edition has been substantially revised and expanded to incorporate the abundance of new scientific information that has been produced since it was first published in 1989. Major additions have been made to every chapter, and new chapters have been added on Neotropical ecosystems, human ecology, and the effects of deforestation. Biodiversity and its preservation are discussed throughout the book, and Neotropical evolution is described in detail. This new edition offers all new drawings and photographs, many of them in color. As enthusiastic readers of the first edition will attest, this is a charming book. Wearing his learning lightly and writing with ease and humor, John Kricher presents the complexities of tropical ecology as accessible and nonintimidating. Kricher is so thoroughly knowledgeable and the book is so complete in its coverage that general readers and ecotourists will not need any other book to help them identify and understand the plants and animals, from birds to bugs, that they will encounter in their travels to the New World tropics. At the same time, it will fascinate armchair travelers and students who may get no closer to the Neotropics than this engagingly written book.

Finding the Forest in the Trees: The Challenge of Combining Diverse Environmental Data

by Committee for a Pilot Study on Database Interfaces

During the last few decades of the 20th century, the development of an array of technologies has made it possible to observe the Earth, collect large quantities of data related to components and processes of the Earth system, and store, analyze, and retrieve these data at will. Over the past ten years, in particular, the observational, computational, and communications technologies have enabled the scientific community to undertake a broad range of interdisciplinary environmental research and assessment programs. Sound practice in database management are required to deal with the problems of complexity in such programs and a great deal of attention and resources has been devoted to this area in recent years. However, little guidance has been provided on overcoming the barriers frequently encountered in the interfacing of disparate data sets. This book attempts to remedy that problem by providing analytical and functional guidelines to help researchers and technicians to better plan and implement their supporting data management activities.

Technological Trajectories and the Human Environment

by Jesse H. Ausubel H. Dale Langford

Technological Trajectories and the Human Environment provides a surprising projection of a much greener planet, based on long-range analysis of trends in the efficient use of energy, materials, and land.The authors argue that we will decarbonize the global energy system and drastically reduce greenhouse gas emissions. We will dematerialize the economy by leaner manufacturing, better product design, and smart use of materials. We will significantly increase land areas reserved for nature by conducting highly productive and environmentally friendly agriculture on less land than is used today, even as global population doubles.The book concludes that the technological opportunities before us offer the possibility of a vastly superior industrial ecology. Rich in both data and theory, the book offers fresh analyses essential for everyone in the environmental arena concerned with global change, sustainable development, and profitable investments in technology.

Wetlands: CHARACTERISTICS AND BOUNDARIES

by Committee on Characterization of Wetlands

Wetlands has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management.This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action.Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels.This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

The Media Ecosystem

by Antonio Lopez

In The Media Ecosystem, Antonio Lopez draws together the seemingly disparate realms of ecology and media studies to present a fresh and provocative interpretation of the current state of the mass media--and its potential future. Lopez explores the connections between media and the environment, arguing that just as the world's powers have seized and exploited the physical territories and natural resources of the earth, so, too, have they colonized the "cultural commons"--the space of ideas that everyone shares. He identifies the root of the problem in the privileging of "mechanistic" thinking over ecological intelligence, which recognizes that people live in a relationship with every other living thing on the planet. In order to create a more sustainable media ecosystem--just like the preservation of organic ecosystems--we must reconnect our daily media activities to their impact on others and the environment. To become "organic media practitioners," we must become aware of the impact of media use on the environment; recognize media's influence on our perception of time, space, and place; understand media's interdependence with the global economy; be conscious of media's interaction with cultural beliefs; and develop an ethical framework in order to act upon these understandings. Above all, Lopez calls for media producers and consumers alike to bring a sense of ritual and collaboration back to the process of communication, utilizing collective intelligence and supporting a new culture of participation. Containing both wide-reaching analysis and practical tips for more conscious media use, The Media Ecosystem is designed for all those who seek a more sustainable future.From the Trade Paperback edition.ent.

Technical Bases for Yucca Mountain Standards

by Committee on Technical Bases for Yucca Mountain Standards

The United States currently has no place to dispose of the high-level radioactive waste resulting from the production of the nuclear weapons and the operation of nuclear electronic power plants. The only option under formal consideration at this time is to place the waste in an underground geologic repository at Yucca Mountain in Nevada. However, there is strong public debate about whether such a repository could protect humans from the radioactive waste that will be dangerous for many thousands of years. This book shows the extent to which our scientific knowledge can guide the federal government in developing a standard to protect the health of the public from wastes in such a repository at Yucca Mountain. The U.S. Environmental Protection Agency is required to use the recommendations presented in this book as it develops its standard.

Science and the Endangered Species Act

by Committee on Scientific Issues in the Endangered Species Act

The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits.In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective.The committee provides an overview of what scientists know about extinction--and what this understanding means to implementation of the ESA. Habitat--its destruction, conservation, and fundamental importance to the ESA--is explored in detail.The book analyzes Concepts of species--how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESA--how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts.

A Plan for a Research Program on Aerosol Radiative Forcing and Climate Change

by National Research Council Staff

This book recommends the initiation of an "integrated" research program to study the role of aerosols in the predicted global climate change. Current understanding suggest that, even now, aerosols, primarily from anthropogenic sources, may be reducing the rate of warming caused by greenhouse gas emissions. In addition to specific research recommendations, this book forcefully argues for two kinds of research program integration: integration of the individual laboratory, field, and theoretical research activities and an integrated management structure that involves all of the concerned federal agencies.

This book, while focusing on current preservation challenges posed by the Aga, or Mariana crow, also reflects the larger issues and challenges of biodiversity conservation in all oceanic island ecosystems. It evaluates causes for the continuing decline of the Aga, which exists on only the two southernmost islands in the Mariana archipelago, Guam and Rota, and reviews actions to halt or reverse the decrease.This book reminds us of the importance and challenge of preserving the unique environmental heritage of islands of the Mariana archipelago, the need for increased knowledge to restore and maintain native species and habitats, and the compelling and lasting value of extensive public education to stimulate environmentally informed public policy development.

An Evaluation of the U.S. Navy's Extremely Low Frequency Communications System Ecological Monitoring Program

by Committee to Evaluate the U.S. Navy's Extremely Low Frequency Communications System Ecological Monitoring Program

The U.S. Navy established an ecological monitoring program to determine whether electric and magnetic fields from extremely low frequency (ELF) communications systems influenced plant and animal populations near the transmitting facilities. Although some of the researchers believe that a few biological changes might have occurred, they concluded that the results do not indicate significant adverse ecological effects.This book evaluates the 11 ecological studies of the Navy's monitoring program and examines the adequacy of experimental design, the data collection and analysis, and the soundness of the conclusions. It also addresses whether the monitoring program was capable of detecting subtle effects due to ELF exposure and examines the biological changes observed by some program researchers, such as enhanced tree growth.

Environmentally Significant Consumption: Research Directions

by Committee on the Human Dimensions of Global Change

There has been much polemic about affluence, consumption, and the global environment. For some observers, "consumption" is at the root of global environmental threats: wealthy individuals and societies use far too much of the earth's resource base and should scale back their appetites to preserve the environment for future generations and allow a decent life for the rest of the world. Other observers see affluence as the way to escape environmental threats: economic development increases public pressure for environmental protection and makes capital available for environmentally benign technologies. The arguments are fed by conflicting beliefs, values, hopes, and fears--but surprisingly little scientific analysis.This book demonstrates that the relationship of consumption to the environment needs careful analysis by environmental and social scientists and conveys some of the excitement of treating the issue scientifically. It poses the key empirical questions: Which kinds of consumption are environmentally significant? Which actors are responsible for that consumption? What forces cause or explain environmentally significant consumption? How can it be changed? The book presents studies that open up important issues for empirical study: Are there any signs of saturation in the demand for travel in wealthy countries? What is the relationship between environmental consumption and human well-being? To what extent do people in developing countries emulate American consumption styles? The book also suggests broad strategies that scientists and research sponsors can use to better inform future debates about the environment, development, and consumption.
