Footprints of the Forest is the clearest and most comprehensive account to date of the relationship between an Amazonian people and their botanical environment. Based on Bal e's ten years of ethnological and botanical research among the Tupi-Guarani-speaking Indians, especially the Ka'apor, of eastern Amazonia, this book documents the ways in which the Ka'apor use, manage, name, and classify many hundreds of plant species found in their habitat. From a historical and ecological perspective, Bal e shows that Ka'apor ethnobotany represents an interpenetration of Amazonian culture and nature and ... View More...
When Europeans first reached the land that would become the United States they were staggered by the breadth and density of the forest they found. The existence of that forest, and the effort either to use or subdue it, have been constant themes in American history, literature, economics, and geography up to the meaning of the forest in American history and culture, he describes and analyzes the clearing and use of the forest from pre-European times to the present, and he traces the subsequent regrowth of the forest since the middle of the twentieth century. Dr Williams begins by exploring the... View More...
In Life in the Balance, Niles Eldredge argues that the Earth is confronting a disaster in the making--an ecological crisis that, if left unresolved, could ultimately lead to mass extinction on the scale of that which killed the dinosaurs sixty-five million years ago. Writing for general readers, he reviews compelling evidence for this "biodiversity crisis," showing that species are dying out at an unnaturally rapid rate. He demonstrates the importance of maintaining biodiversity, taking the reader on a journey that reveals the twin faces of biodiversity--over thirteen million living species an... View More...
As in other areas of conservation, the crucial question concerning plant biodiversity isn't whether to conserve but how best to conserve diversity at the different levels of biological organization--the gene, the species and the community. Conservation biology is faced with several controversial issues, such as the dichotomy between the preservation of individual species versus a broader focus on the environment, the relative importance to give to endangered species, the design and management of reserves, and the drive for increasing agricultural productivity through plant improvement versus t...

The world ocean is one of the most important global resources. Without it most life on earth would not survive because the ocean provides temperature regulation and produces oxygen, among other vital functions. However, this life-sustaining resource faces dangerous threats from over fishing, industrial wastes, oil pollution, and loss of biodiversity.Ocean Politics and Policy covers the major types of pollution, deep sea-bed mining, international jurisdictional disputes, and piracy, examining the underlying reasons for these problems and providing practical policy suggestions for reducing their...

The 1989 report of the National Research Council, Global Change and Our Common Future states: Our planet and global environment are witnessing the most profound changes in the brief history of the human species. Human activity is the major agent of those changes--depletion of stratospheric ozone, the threat of global warming, deforestation, acid precipitation, the extinction of species, and others that have not become apparent. One human activity that leads to all of these global changes is the burning of the world's living and dead vegetation. And human-initiated biomass burning has increased... View More...
How will patterns of human interaction with the earth's eco-system impact on biodiversity loss over the long term--not in the next ten or even fifty years, but on the vast temporal scale be dealt with by earth scientists? This volume brings together data from population biology, community ecology, comparative biology, and paleontology to answer this question. View More...
Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practi... View More...
Over the past ten years an increasing number of field entomologists and farmers have recognized that conservation of natural enemies is important to effective biological control in many agricultural systems. This collection addresses an important gap in the biological control literature by providing the first comprehensive summary of recent findings on habitat manipulation to control pests. Enhancing Biological Control includes contributions from experts around the world: the United States, Finland, Germany, Great Britain, People's Republic of China, and Switzerland. Chapters cover habitat mod... View More...
Ecosystem management has gained widespread visibility as an approach to the management of land to achieve sustainable natural resource use. Despite widespread interest in this emerging management paradigm, Ecosystems: Balancing Science with Management is the first book to directly propose approaches for implementing ecosystem management, give examples of viable tools, and discuss the potential implications of implementing an ecosystem approach. These ideas are framed in a historical context that examines the disjunction between ecological theory, environmental legislation and natural resource... View More...
