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.

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.

Download Sustainable Use and Development of Watersheds Book in PDF, ePub and Kindle
John Wesley Powell, U.S. scientist and geographer, put it best when he said that a watershed is: ...that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community. Watersheds come in all shapes and sizes. They cross sectorial boundaries (e.g. county, state/province, and country). No matter where you are, you are in a watershed! World-wide, watersheds supply drinking water, provide r- reation and respite, and sustain life. Watersheds are rich in natural capital, producing goods (agriculture and fisheries products) and services (industry and technology) for broad geographic areas. In many countries, at the base of watersheds where tributaries empty into large water-bodies (e.g. estuaries, seas, oceans) are centers of society and are typically densely populated areas. These areas serve as concentrated centers of the socio-economic system. They also are centers of domestic and international trade, tourism, and c- merce as well as the center of governments (capitals) where local, regional and national legislatures are located. As we all live in a watershed, our individual actions can directly affect it. The cumulative effects of all the individual actions of everyone within a watershed may be, and often are devastating to the quality of water resources and affect the health of living things including humans. Therefore, watershed systems are highly subject to threat to human security and peace.

Acknowledging the present inability to determine objectively the status and trends among estuarine ecosystems, the environmental research community has recently stepped up efforts to develop and evaluate meaningful estuarine indicators. This goal requires the effort of researchers from a broad spectrum of disciplines. In order to expedite this init

Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation. This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processesâ€"explaining why each indicator is useful, what models support the indicator, what the measured values will mean, how the relevant data are gathered, how data collection might be improved, and what effects emerging technologies are likely to have on the measurements. The committee reviews how it arrived at its recommendations and explores how the indicators can contribute to policymaking. Also included are interesting details on paleoecology, satellite imagery, species diversity, and other aspects of ecological assessment. Federal, state, and local decision-makers, as well as environmental scientists and practitioners, will be especially interested in this new book.

Download Coastal Monitoring through Partnerships Book in PDF, ePub and Kindle
As the coastal human population increases in the United States, there will likely be increasing environmental and socioeconomic pressures on our coastal and estuarine environments. Monitoring the condition of all our nation's coastal and estuarine ecosystems over the long term is more than any one program can accomplish on its own. Therefore, it is crucial that monitoring programs at all levels (local, state, and federal) cooperate in the collection, sharing, and use of environmental data. This volume is the proceedings of the Coastal Monitoring Through Partnerships symposium that was held in Pensacola, Florida in April of 2001, and was organized by the U.S. Environmental Protection Agency's (EPA's) Environmental Monitoring and Assessment Program (EMAP), and the Council of State Governments (CSG). It contains papers that describe various multi-disciplinary coastal and estuarine environmental monitoring programs, designed and implemented by using regional and national partnerships with federal and state agencies, academia, Native American tribes, and nongovernmental organizations. In addition, it includes papers on modeling and data management; monitoring and assessment of benthic communities; development of biological indicators and interlaboratory sediment comparisons; microbiological modeling and indicators; and monitoring and assessment of phytoplankton and submerged aquatic vegetation. There are many components involved in determining the overall impacts of anthropogenic stressors on coastal and estuarine waters. It will take strong partnerships like those described in this volume to ensure that we have healthy and sustainable coastal and estuarine environments, now and in the future.
