In the late 1970s and early 1980s, our nation began to grapple with the legacy of past disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive Envir- mental Response, Compensation, and Liability Act (CERCLA), commonly known as Sup- fund, it became the law of the land to remediate these sites. The U. S. Department of Defense (DoD), the nation’s largest industrial organization, also recognized that it too had a legacy of contaminated sites. Historic operations at Army, Navy, Air Force, and Marine Corps facilities, ranges, manufacturing sites, shipyards, and depots had resulted in widespread contamination of soil, groundwater, and sediment. While Superfund began in 1980 to focus on remediation of heavily contaminated sites largely abandoned or neglected by the private sector, the DoD had already initiated its Installation Restoration Program in the mid-1970s. In 1984, the DoD began the Defense Environmental Restoration Program (DERP) for contaminated site assessment and remediation. Two years later, the U. S. Congress codified the DERP and directed the Secretary of Defense to carry out a concurrent program of research, development, and demonstration of innovative remediation technologies. As chronicled in the 1994 National Research Council report, “Ranking Hazardous-Waste Sites for Remedial Action,” our early estimates on the cost and suitability of existing techn- ogies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

The discussion of ideas, methods, scientific results, empirical practices and perspectives on the restoration of high diversity tropical and subtropical forest formations is the objective of this book; however, principles here proposed may be used in other less complex forest formations. Special attention is given to the role of the ecological processes on the restoration of functional forest communities, once the composition and structure of these natural or even restored communities change in space and time.

Seed Biology, Volume I: Importance, Development, and Germination is a part of a three-volume treatise, which aims to bring together a large body of important information on seed biology. Organized into six chapters, this book begins with a discussion on the importance and characteristics of seeds. Separate chapters follow that discuss the development of gymnosperm and angiosperm seeds, as well as the anatomical mechanisms of seed dispersal. Other chapters focus on the morphogenetic events involved in the germination and the scientific basis for the concept of physiological predetermination or seedling vigor, including the potential application of this concept in agriculture, forestry, and management of natural resources. This work will be useful to various groups of research biologists and teachers, including plant anatomists, pathologists, and physiologists as well as agronomists, biochemists, ecologists, entomologists, foresters, and horticulturists.

This book describes native bees generally and provides a complete guide to keeping Australian native stingless bees. It is richly illustrated with over 500 photos, drawings and charts to increase accessibility and aid learning. It is written by an expert who has spent his lifetime intimately engaged with these unique creatures. Keeping native stingless bees is a hot topic in Australia for commercial, environmental and recreational reasons. You can do something about the decline of pollinators by conserving native bees. Whether you keep a hive or two in your suburban garden, or want to use multiple hives on a commercial farm, this friendly guide has you covered. Bee biology, behaviour, nesting, social life and foraging; How to build your own native bee hive; How to transfer a bee colony to a hive box and propagate hives; All about sugarbag honey, including how to extract it from hives; Managing your hive; Identifying and dealing with pests; Using stingless bees for pollination - from small gardens to commercial crops; A complete list of Australia's stingless bee species, how to identify them, their characteristics, where they occur, and recommended hives; A readable summary of the latest research on native bees.

Although biologists have directed much attention to estimating the extent and causes of species losses, the consequences for ecosystem functioning have been little studied. This book examines the impact of biodiversity on ecosystem processes in tropical forests - one of the most species-rich and at the same time most endangered ecosystems on earth. It covers the relationships between biodiversity and primary production, secondary production, biogeochemical cycles, soil processes, plant life forms, responses to disturbance, and resistance to invasion. The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes.

Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.
