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.

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.

Indexes material from conference proceedings and hard-to-find documents, in addition to journal articles. Over 1,000 journals are indexed and literature published from 1981 to the present is covered. Topics in pollution and its management are extensively covered from the standpoints of atmosphere, emissions, mathematical models, effects on people and animals, and environmental action. Major areas of coverage include: air pollution, marine pollution, freshwater pollution, sewage and wastewater treatment, waste management, land pollution, toxicology and health, noise, and radiation.
