This book examines the application of fish community characteristics to evaluate the sustainability and biological integrity of freshwaters. Topics include perspectives on use of fish communities as environmental indicators in program development, collaboration, and partnership forming; influence of specific taxa on assessment of the IBI; regional applications for areas where the IBI had not previously been developed; and specific applications of the IBI developed for coldwater streams, inland lakes, Great Lakes, reservoirs, and tailwaters.

Ecological indicators address ecosystems structure and/or function and are commonly used to provide synoptic information about their state. Through quantitative representations of either the forces that steer ecosystems, responses to forcing functions, or of previous, current, or future states of an ecosystem, indicators are expected to reveal conditions and trends that will help in development planning and decision making processes. Ecological indicators combine numerous environmental factors in a single value, which may be useful in terms of management and in the development of ecological concepts, compliant with the general public's understanding. Nevertheless, their application is not exempt of criticisms, the first of which is that aggregation results in an oversimplification of the ecosystem under observation. Ecological indicators must therefore be handled following the right criteria and in situations that are consistent with its intended use and scope; otherwise they may drive to confusing interpretations of data.

The field of ecosystem health explores the interactions between natural systems, human health, and social organization. As decision makers require a sound, modular approach to environmental management and sustainable development, ecosystem health assessment indicators are increasingly used across any number of applications.

Experience demonstrates that none of the available measures regarding biological effects of pollution can be considered ideal, which is due to the complexity inherent in assessing the environmental quality of a system. In fact, it is always preferable to combine a suite of indices providing complementary information. This book aims at helping researchers and students, as well as managers and authorities of coastal areas in selecting the most suitable ecological indicators for each case, taking into account the type of disturbance they want to assess and the data available to do it. A user friendly guide is proposed, accounting different theoretical approaches and discussing the results of its application in different geographical areas. Recommendations are provided regarding the most adequate application of different indices, illustrating for instance in what situations their use is recommendable, or on the contrary not advisable, depending on the characteristics of the disturbance, the type of data, or the level of taxonomic identification of the organisms.

Ecosystem management has emerged in the past several years as the new paradigm for managing public and private land. It combines the principles of ecosystem-level ecology with the policy requirements of resource and public land management. This collection of selected readings will serve as an introduction to the concepts of biological diversity, ecological process, biotic integrity, and ecological sustainability that underlie ecosystem management.
