Our lack of knowledge of the organisms dwelling in soils and sediments and of their roles in ecological processes constitutes a major barrier to understanding how ecosystems operate. This topic has both academic and applied relevance. Thus, in order to forecast the implications of perturbations in a site on both the species present and the ecosystem functioning, whether direct (e.g. pollution or physical disturbance) or indirect (e.g. climate change), methods need to be available that can be used to ascertain what organisms are present in a sample.
This book provides an authoritative manual of the techniques now used for different organisms. It has been developed as part of a project initiated by the International Union of Biological Sciences (IUBS), supported by UNESCO. It covers both soil organisms and those inhabiting freshwater and marine sediments, from microbes (bacteria, algae, fungi, etc.) to macrofauna (earthworms, nematodes, molluscs, etc.). The chapters are arranged by organismal groups and have been written by recognized specialists from the USA and Europe. The book makes a major contribution to the literature and is indispensable for soil and aquatic biologists and ecologists, as well as those with a broader interest in biodiversity and environmental sciences.

CHOICE Review

This valuable manual is original and complete in that it covers in one volume the range of macro- and microorganisms found in soil and sediments and also those found in water trapped in sediments. There are 22 chapters, each addressing a different group of organisms; each progresses from an introduction and background to a review of methods used for their examination, followed by detailed explanations of specific techniques for examination and enumeration. Often step-by-step procedures are given, or recipes for media are provided in an appendix format. Protocols described include simple laboratory methods as well as molecular and other state-of-the art techniques used in the study of these organisms. Suggestions are also provided for research still needed on the group of organisms covered, or limitations to the methods described. A valuable addition to collections on biodiversity, since too often soil organisms and microbes are overlooked in treatment on biodiversity. Recommended for upper-division undergraduates, graduate students, and research professionals. D. L. Richter; Michigan Technological University
