In this complete and thorough update of Arthur Boucot s seminal work, Evolutionary Paleobiology of Behavior and Coevolution, Boucot is joined by George Poinar, who provides additional expertise and knowledge on protozoans and bacteria as applied to disease. Together, they make the Fossil Behavior Compendium wider in scope, covering all relevant animal and plant groups and all epochs, and providing a detailed review of animal and plant fossil behavior in terrestrial and aquatic environments.

Fossil behavior encompasses not only past evidence of the...

Ever since the concept of the "struggle for life" became the heart of Darwin's theory of evolution, biologists have studied the relevance of interactions for the natural history and evolution of organisms. Although positive interactions among plants have traditionally received little attention, there is now a growing body of evidence showing the effects of positive interactions between higher plant species. Written by international experts, Positive Plant Interactions and Community Dynamics reviews these developments with particular emphasis on positive interactions and...

When men and women who work with toxic materials get sick, everyone needs to worry. The toxic circles of industrial hazards spread in successive waves outward: from the workplace to the home, to the neighborhood, and to the community at large. These compelling essays tell how the links between cancers and working with radium, waxes, and dyes were uncovered and how poisoning from lead, mercury, dioxin, and chromium in and around the factory was detected. They document how corporations, government agencies, courts, unions, physicians, workers, and citizens have tried to ignore, evade, and...

Addresses Emerging Wildlife Threats in One Concise Volume

A decade ago, many of these threats existed but...

Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag. Usually carried out at the mine site, it saves time and costs and allows selective, profitable bulk mining. This practical guide presents the essentials of mineral dressing and its support operations. It explains the terms and techniques and provides basic formulas, methods and practical...

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.

This 30^st jubilee volume (2010) of "Palaeoecology of Africa" looks back and reflects the "state of the art" of what is actually known on former African climates and ecosystems in the format of review articles authored by specialists in the field. New research articles on climate and ecosystem dynamics as well as applied topics on geomorphic hazards and future environmental trends in Africa are included.
This book will be of interest to all concerned with ecosystems dynamics, tropical forests, savannahs, deserts and related development problems of third world...
