Book Description
Dynamic and productive ecosystems, coastal lagoons play an important role in local economies and often bear the brunt of coastal development, agricultural, and urban waste, overuse from fisheries, aquaculture, transportation, energy production, and other human activities. The features that make coastal lagoons vital ecosystems underline the importance of sound management strategies for long-term environmental and resource sustainability. Written by an internationally renowned group of contributors, Coastal Lagoons: Critical Habitats of Environmental Change examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them. The contributors examine the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms, droughts and other climate effects, and the resulting biotic and ecosystem impairments that have developed worldwide. They provide detailed descriptions of the physical-chemical and biotic characteristics of diverse coastal lagoonal ecosystems, and address the environmental factors, forcing features, and stressors affecting hydrologic, biogeochemical, and trophic properties of these important water bodies. They also discuss the innovative tools and approaches used for assessing ecological change in the context of anthropogenically- and climatically-mediated factors. The book investigates the biogeochemical and ecological responses to nutrient enrichment and other pollutants in lagoonal estuaries and compares them to those in other estuarine types. With editors among the most noted international scholars in coastal ecology and contributors who are world-class in their fields, the chapters in this volume represent a wide array of studies on natural and anthropogenic drivers of change in coastal lagoons located in different regions of the world. Although a significant number of journal articles on the subject can be found in the literature, this book provides a single-source reference for coastal lagoons within the arena of the global environment.

Book Description
This book reviews the origin, development, morphology, environment and ecology of the world's coastal lagoons. There are particularly extensive series of lagoons - areas of salt or brackish water separated from the adjacent sea by a low-lying sand or shingle barrier - along the eastern and Gulf of Mexico coasts of the USA, in Mexico itself, in Brazil, West Africa, Natal, southern and eastern India, south-west and south-east Australia, Alaska, Siberia and around the shores of the Mediterranean, southern Baltic, Black and Caspian Seas. In several of these areas they support important fisheries. This book summarises what is known of the formation and fate of lagoons, the lagoonal environment, lagoonal ecology, the strategies of lagoonal species, the human use of lagoons, besides containing a general introduction and a section on methods for the study of coastal lagoons.

Book Description
This document is prepared for fisheries biologists, managers and administrators concerned with lagoon fisheries and aquaculture. Our main objective is to draw attention to the need for greater understanding of relationships between the hydraulics and productivity of lagoon fish and shellfish. The fishery yields from lagoons vary widely, and, probably, predictably, once such relationships are understood. Furthermore, the productivities of many lagoons could probably be enhanced by hydraulic manipulations, but the hydraulic manipulation is presently risky, except in dystrophic lagoons. The document includes a description of lagoon physics, how hydraulics are likely linked to lagoon productivity, how lagoons might be expected to respond to hydraulic alterations, and a protocol for physical investigations. This latter is a necessary step to protect as well as enhance fisheries and aquaculture resources in lagoons, which are especially vulnerable to degradation and overexploitation.

Book Description
This multidisciplinary volume comprehensively reviews our current knowledge of the effects of urban, industrial and agricultural pollution on the biology of shallow coastal marine lagoons. All the authors are internationally recognized authorities and have had many years of experience in their respective fields. The major strength of this volume is that it integrates several fields of research including biogeochemistry, marine microbiology, marine algology and marine zoology. By adopting such a strategy the reader is provided with a clear insight of the key processes involved in lagoon eutrophication and dystrophy and their impact on the different biological communities which live in such environments. This book will therefore provide an essential reference work for environmental biologists, ecologists, microbiologists and those involved in the management and commercial exploitation of these economically important ecosystems.

Book Description
Lagoon Environments Around the World - A Scientific Perspective covers a wide range of topics. Typically bordering between land and sea, lagoons are among the most diversely utilized waterways on the planet. Lagoons are extremely important environments socio-economically, and their usage places ever increasing stress on these very sensitive aquatic regions. The effective management of shallow aquatic environments requires a detailed scientific understanding of the various contributary natural processes. This has both environmental and economic implications, especially where there is any anthropogenic involvement. This book draws on international scientific research to examine the following lagoon related issues: classification, circulation hydrodynamics, ecosystems, sedimentation, anthropogenic stresses, and response to extreme events. The research was carried out by researchers who specialize in shallow water processes and related issues.

Book Description
Coastal Zones and Estuaries is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources which is part of the global Encyclopedia of Life Support Systems (EOLSS), an integrated compendium of twenty one Encyclopedias. The Theme deals with important links of water, sediment, and nutrients between continents and oceans. The present behavior of sea level, ice sheets, and coral reefs is still a matter of controversy and concern. Coastal experiences learned in developed countries should be used to improve coastal policies world wide. Within the Global Change Programme, it is recognized that the earth system is characterized by critical limits and abrupt changes. The coastal systems are particularly sensitive to these changes. This volume is aimed at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Book Description
Lagoons and estuaries are transition spaces between earth and sea. Beyond their expanse, geographic repartition, geomorphological, hydroclimatic and ecobiological diversity and biodiversity, they play an important role in regional economies and are some of the ecosystems most vulnerable to global change. Reinforced by numerous references, this book studies Mediterranean lagoonal and estuarine fishes whose diversity largely depends on the composition of neighboring marine and continental ichtyofauna. The authors describe their morphological, biological, ecological and behavioral characteristics by evoking their distinctive features and differences with their marine or freshwater homologues. Their adaptation strategies, elucidated thanks to recent advances in morphology, genetics and molecular biology, are recognized as a major advantage in the context of climate change. This book is for natural environment managers, engineers, teachers, students and researchers.

Book Description
"The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons' ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons' environment."--Publisher's description.
