Book Description
Designed as a textbook, this volume is an important, up-to-date, authoritative, and accessible survey in ecology of freshwater and estuarine wetlands. Prominent wetland scholars address the physical environment, geomorphology, biogeochemistry, soils, and hydrology of both freshwater and estuarine wetlands. Careful syntheses review how hydrology and chemistry constrain wetlands plants and animals. In addition, contributors document the strategies employed by plants, animals, and bacteria to cope with stress. Focusing on the ecology of key organisms, each chapter is relevant to wetland regulation and assessment, wetland restoration, how flood pulses control the ecology of most wetland complexes, and how human regulation of flood pulses threatens wetland biotic integrity. Ideal for the classroom, this book is a fundamental resource for anyone interested in the current state of our wetlands. ... Read more

Outstanding as textbook, or as personal reference source.
While taking an Introductory course in Oceanography at St.Petersburg Jr.College (FL) I found a copy of this wonderful work in the library. Their acquisition cost was just over $50.00, I see that it now sells for over$100.00, thus I am not sure I wish to buy my own copy. For anyone in thefield, it would be a fine additon to their personal library, if one was notin the nearby Public, or College, stacks. While I was particularlyinterested in the Ecology of Tamp Bay (Fl.) I still found enough basicinformation which I can related to our Estuary here. I am particularlyinterested in NEKTON (Blue Crabsand Shriimp) and this text treated themsufficiently well to answer my basic questons. (Net surfers: use yourbrowser on topics such as Estuarine research, Tampa Bay Estuary, etc as agood starting point. This is a fine text, and a scholarly work. It ispublished by Wiley-Interscience Pubs and certainly carriestheir finereputation for worthwhile reading. Those who can handle a modicum of mathwill enjoy the text, but I rather doubt that the casual reader will ''staywith it'', although it certainly makes a pleasant read, for either anIntroductorystudent, like the undersigned, or for someone who isresearching the Science of Oceanography. Too bad it so expensive, it wouldmake a good first year course. As a retired pharmacist, I readmanyscience texts and can only conclude by saying that this one text wouldcertainly fill an important niche in your own personal science library, ifyou were looking for something on this topic. I guess I will order myself acopy, as I feel that John Day, Charles Hall and W.Mchael Kemp have done asplendidjob. Alejandro Yanex-Arancibia brings his vast knowledge ofecology as seen by one from the areas south of the US, in an interestingmanner. How would I approve on it? If they ever do an update version, Iwould love to see chapters on South Pacific benthic organisms, as well assome treatment of life under the Arctic and Antarctic Seas, and maybe throwin some information on other extreme environments such as the Dead Sea, andocean vent tube worms,that sort of thing...

Book Description

Estuaries are the point of convergence for almost the entire array of coastal and ocean environmental issues. Management of these rapidly changing environments requires a whole-system perspective that includes integration of all available knowledge of the ecology, chemistry, and physics of estuaries. Yet estuarine research has been primarily short-term and site-specific, providing few insights that can be generalized and applied to a broader understanding of these complex ecosystems. Estuarine Science addresses that problem by presenting examples of synthetic approaches to estuarine science. Leading scientists-including Donald F. Boesch, W. Rockwell Geyer, Nancy Rabalais, Charles A. Simenstad, and many others-offer twelve chapters that report on different types of ecological synthesis and summarize the current state of scientific knowledge. Additional chapters examine the adequacy of existing synthesis, and the data and models required for improving the scientific management of estuaries in the coming decade.

Each of the book's five sections introduces a major area of estuarine syntheses; highlights key problems about that topic; reports case histories of successful synthesis; and recommends types of data to collect, processes to study, and models to build for a predictive understanding. Sections examine:

• inputs to estuaries of water, sediment, and nutrients from the drainage basin
• the coupling of estuarine physics with biogeochemistry and ecology
• the biogeochemical process in estuaries and their linkages to the food web
• controls on the distribution and abundance of organisms in the estuary
• the need for synthesis that would directly improve the scientific management of estuaries

Estuarine Science synthesizes what has been learned from the intensive research in many different estuarine projects around the country. It will be an essential work for professional scientists and graduate students working in coastal or estuarine research, as well as for managers, planners and environmentalists involved with coastal and estuarine issues. ...

Book Description
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 initiative, many of the world's leading estuarine scientists came together to present their views at the 2003 Estuarine Indicators Workshop.Derived from this conference of leading estuarine scientists, Estuarine Indicators presents the principles, concepts, practical use, and application of indicators in estuarine research and management practices. Topics include: the theory behind environmental indicators and their presumed attributes; the methods and protocols of indicator development and evaluation; a presentation of effective and ineffective indicator examples; and discussions of the future directions in research and management practices.This is an ideal reference for researchers, scientists, and students from any field dealing with estuaries and estuarine ecosystems. Its introductory-level chapters are accessible to novices and seasoned experts alike, and the applications and interpretation of research data suit the needs of environmental managers. This is a truly multidisciplinary, comprehensive compendium upon which future research will undoubtedly be built. ... Read more

Book Description
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.

Book Description

It is a well-known fact that eutrophication of coastal waters causes significant changes in the species composition of the primary producers. Usually a shift from an ecosystem dominated by sea grasses or large brown algae to an ecosystem dominated by fast-growing green algae or phytoplankton is observed. While this shift has been documented in a number of research papers and books, the consequences of this shift are less well known. This book focuses on the consequences of such changes for nutrient cycling.

Description:
The present study aimed to investigate into the feeding ecology of the dominant copepods along a salinity gradient in Chikugo estuary. Copepod composition was studied from samples collected from stations positioned along the salinity gradient of the estuary. Copepod gut pigment concentrations were measured by fluorescence technique and hydrographical parameters such as temperature, salinity, transparency, suspended particulate matter (SPM); pigments such as chlorophyll-a (Chl-a), phaeopigment; and particulate nutrients such as particulate organic carbon (POC) and particulate organic nitrogen (PON) were measured. Two distinct zones in terms of nutrient and pigment concentrations as well as copepod distribution and feeding were identified along the estuary. We identified a zone of turbidity maximum (TM) in the low saline upper estuary which was characterized by having higher SPM, higher POC and PON but lower POC:PON ratios, higher pigment concentrations but lower Chl-a/SPM ratios and higher copepod dry biomass. Sinocalanus sinensis was the single dominant copepod in low saline upper estuary where significantly higher concentrations of nutrients and pigments were recorded and a multispecies copepod assemblage dominated by common coastal copepods such as Acartia omorii, Oithona davisae and Paracalanus parvus was observed in the lower estuary where nutrient and pigment concentrations were lower. Copepods in the estuary are predominantly herbivorous, feeding primarily on pigment bearing plants. However, completely contrasting trophic environments were found in the upper and the lower estuary. It was speculated from the Chl-a and phaeopigment values that copepods in the upper estuary receive energy from a detritus-based food web while in the lower estuary an algal-based food web supports copepod growth. Overall, the upper estuary was identified to provide a better trophic environment for copepod and is associated with higher SPM concentrations and elevated turbidity. The study demonstrates the role of estuarine turbidity maximum (ETM) in habitat trophic richness for copepod feeding. The study points out the role of detritus-based food web as energy source for the endemic copepod S. sinensis in the upper estuary, which supports as nursery for many fish species. ... Read more

Book Description
Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study.

The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend.

The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia.

Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught. ...

Book Description
The well documented history of pollution and recovery in the Thames Estuary has made the system one of the world's most famous case studies. However, the story is incomplete in terms of the status of the rehabilitated ecosystem resulting from the remedial management policies. What ecosystem might we expect to recover from a once lifeless estuary? have the extensive efforts made by policy makers, environmental managers and scientists resulted in a diverse, complex estuary that may be a model for other systems? This book draws together many detailed aspects of the recovering Thames Estuary ecosystem from environmental management and scientific sources. The result is probably the most comprehensive account of the management and ecology of a single estuarine system yet produced. It includes important and extensive long term studies of the fish communities, water quality and management policy, spatial accounts along the full length of the estuary for benthic invertebrates and algae, significant case studies on zooplankton, saltmarshes and parasitology, as well as an overview looking forward to the next millennium. Altogether, this study of the long term ecological consequences of management policy provides a benchmark for comparison with other estuarine ecosystems, both `natural' and rehabilitated, and forms a unique and valuable reference for environmental managers, estuarine scientists and ecologists. ...
