Genre: Science

For the inhabitants of many of the world's major towns and cities, estuaries provide their first and nearest glimpse of a natural habitat. Despite the attempts of man to pollute or reclaim it, the estuarine ecosystem continues to provide a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. When the previous editions of this book appeared, biologists were beginning to realize that the estuarine ecosystem was an ideal habitat in which to observe the processes controlling biological productivity. In the intervening period, many more estuaries and their inhabitants have been studied intensively. It is now possible to answer many of the questions posed by the earlier editions, and to pursue further the explanation of high productivity in estuaries and of energy utilization at different trophic levels within estuarine food webs. A significant amount of new information has also been accumulated on the human use and abuse of these habitats, particularly the effects of pollution. Although the world's seas are vast and may appear capable of receiving unlimited quantities of human effluent, such waste is often first discharged into the confined waters of estuaries. In practice, marine pollution is often essentially estuarine pollution. To reflect the huge impact of humans on estuaries, and to consider how we may either modify, remove or enrich the estuarine ecosystem, three completely new chapters have been prepared in this edition. These consider anthropogenic change (including pollution) in estuaries, the diverse uses and abuses of the estuarine habitat by man, and the methods used to study human induced changes in estuaries. Finally, this text examines the ways in which estuarine management can monitor, control or prevent the pollution and destruction of this fragile ecosystem.

Estuarine Ecohydrology

Author: Eric Wolanski
Publisher: Elsevier
ISBN: 9780444634146
Release Date: 2015-08-20
Genre: Science

Estuarine Ecohydrology, Second Edition, provides an ecohydrology viewpoint of an estuary as an ecosystem by focusing on its principal components, the river, the estuarine waters, the sediment, the nutrients, the wetlands, the oceanic influence, and the aquatic food web, as well as models of the health of an estuary ecosystem. Estuaries, the intersection of freshwater and coastal ecosystems, exhibit complex physical and biological processes which must be understood in order to sustain and restore them when necessary. This book demonstrates how, based on an understanding of the processes controlling estuarine ecosystem health, one can quantify its ability to cope with human stresses. The theories, models, and real-world solutions presented serve as a toolkit for designing a management plan for the ecologically sustainable development of estuaries. Provides a sound knowledge of the physical functioning of an estuary, a critical component of understanding its ecological functioning Ideal reference for those interested in marine biology, oceanography, coastal management, and sustainable development Describes the essentials behind conceptual and numerical models of the health of an estuary ecosystem and how to use these models to quantify both human impacts and the value of remediation and management measures Chapters are written in an accessible way that encourages collaboration between aquatic, marine, and wetland biologists, ecologists, oceanographers, geologists, geomorphologists, chemists, and ecosystem modelers Covers the physical, chemical, and biological elements of estuary environments, indicating that the essence of an estuary’s functioning lies in its connectivity with the adjacent catchment and the marine/coastal system

Ecology of marine sediments

Author: John Stuart Gray
Publisher: Oxford University Press, USA
ISBN: UOM:39015079360130
Release Date: 2009
Genre: Science

Marine sediments provide the largest habitat on planet earth, yet knowledge of the structure and function of their flora and fauna continues to be poorly described in current textbooks. This concise, readable introduction to benthic ecology builds upon the strengths of the previous edition but has been thoroughly revised throughout to incorporate the new technologies and methods that have allowed a rapid and ongoing development of the field. It explores the relationship between community structure and function, and the selection of global examples ensures an international appeal and relevance. The economic value of marine sediments increases daily, reflected in the text with a new emphasis on pollution, climate change, conservation, and management. This accessible textbook is suitable for both advanced undergraduate and graduate students who have had a general ecology course, but no further training in benthic ecology. It will also be of relevance and use to professional researchers and consultants in marine ecology and environmental science who seek a compact but comprehensive introduction to benthic ecology.

Estuarine Pollution in the Lower Gangetic Delta

Author: Abhijit Mitra
Publisher: Springer
ISBN: 9783319933054
Release Date: 2018-08-13
Genre: Science

This book critically analyzes the water quality in the lower Gangetic delta, and examines the environmental conditions and physical processes operating in this rich ecosystem. Readers with an interest in environmental science, geography, oceanography, marine biology, environmental biology, aquatic pollution and ecology will find the research presented here most appealing. Readers will discover critical aspects of the chemistry of the estuarine water (particularly that of Hooghly and Matla estuaries) in the lower stretch of the delta region along with the causes and effects of pollution in and around this region. Particular attention is given to the bioaccumulation of conservative pollutants in edible fishes and floral communities thriving in this region. Several case studies are also incorporated to highlight the vulnerability of pollution in this region. Chapters also address the impacts of climate change (specifically acidification) on the concentration and behavior of conservative pollutants. Finally, the book highlights some mitigation measures at the technology and policy level to minimize the negative impacts posed by different groups of pollutants on the estuarine biodiversity.

Brazilian Estuaries

Author: Paulo da Cunha Lana
Publisher: Springer
ISBN: 9783319777795
Release Date: 2018-07-09
Genre: Science

This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.
