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.

Book Description
St Lucia is the world's oldest protected estuary and Africa's largest estuarine system. It is also the centerpiece of South Africa's first UNESCO World Heritage Site, the iSimangaliso Wetland Park, and has been a Ramsar Wetland of International Importance since 1986. Knowledge of its biodiversity, geological origins, hydrology, hydrodynamics and the long history of management is unique in the world. However, the impact of global change has culminated in unprecedented challenges for the conservation and management of the St Lucia system, leading to the recent initiation of a project in support of its rehabilitation and long-term sustainability. This timely volume provides a unique source of information on the functioning and management of the estuary for researchers, students and environmental managers. The insights and experiences described build on over 60 years of study and management at the site and will serve as a valuable model for similar estuaries around the world.

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. The book provides a concise readable introduction to estuarine ecology. First published in 1981, it soon established itself as the principle textbook of choice in the UK & NW Europe. This new edition builds upon the strengths of the earlier editions but has been thoroughly revised throughout. The new co-author brings a human impact dimension to the revised book. It is written for advanced undergraduate and graduate students (particularly taught masters) who have had a general ecology course, but no further training in estuarine science. It will be useful to both professional researchers and practical managers in marine ecology and environmental science who seek a compact but comprehensive introduction to estuarine ecology.

Book Description
Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses on monitoring and modelling of coastal eutrophication, and adaptive and science-based nutrient management strategies. The book is based on selected papers from the Second International Symposium on Research and Management of Eutrophication in Coastal Ecosystems, held 20-23 June 2006 in Nyborg, Denmark.

Book Description
Worldwide, marine ecosystems have been lost and degraded due to anthropogenic disturbances. For example, oyster reefs have declined by at least ∼85%, coral reefs by ∼19%, seagrasses by ∼29%, North American salt marshes by ∼42%, and mangroves by ∼35% from the early 19th century. Deepwater reefs and deep-sea vents are not immune and have also been reduced in extent in many areas. Factors driving these losses include habitat destruction, pollution, invasive species, overfishing, trawling, mining and, more recently, climate change effects, such as ocean warming, species range changes and acidification. These habitat declines are occurring at a time when marine waters are being used at or near their maximum productive capacity to meet the contemporary needs of an ever-increasing human population. Because coastal and marine ecosystems generate some of the richest biodiversity hotspots on Earth, and provide critical ecosystem services, including storm protection, fisheries production, and carbon storage, over 1 billion US dollars have been spent globally in an attempt to halt and reverse observed declines. Early conservation efforts aimed at protecting these valuable and threatened habitats focused on reducing human impacts and physical stressors. However, with habitat degradation continuing and sometimes increasing in rate, it is now clear conservation alone will not be sufficient to protect and reestablish coastal ecosystems. Habitat restoration, although in existence for many decades, has recently been elevated as a new primary strategy to stem and even reverse coastal habitat loss. The call for increasing investment in restoration efforts has emerged with significant advances in propagule rearing and dispersion of habitat-forming organisms (e.g., oysters, seagrasses, corals). In addition, restoration resources are increasingly allocated by governments and/or large corporations with the aim to, for example, fix past landscape engineering efforts that had unintended environmental consequences. Such investments are being made to (i) provide jobs for those unemployed during economic downturns, (ii) restore ecosystems destroyed by natural disasters and stressors, (iii) increase coastal defense in response to increased frequency of intense storms, and/or (iv) compensate for pollution-and development-driven habitat degradation. Conservation practitioners have traditionally been skeptical to invest heavily in restoration at large-scales because of the high cost per area (10,000-5,000,000 US$/ha for coastal vs. 500-5,000 US$/ha for terrestrial systems) to replant coastal ecosystems and/or the high chance that the restored ecosystems will not live long (e.g. outplanted corals). For restoration to be effective and employed as a primary method of coastal conservation at relevant scales, we must improve its efficiency, lower costs and rapidly share and incorporate advances. One crucial step will be to identify when and where restoration attempts have been carried out according to state-of-art ecological theory and gauge their success. Another is generating synthesis studies that focus both within and across ecosystems to identify efficiencies, adaptations and innovations. Work that shows theoretical and methodological innovations in specific ecosystems as well as across systems will be critical to pushing all fields of MER forward. Although there is rapidly increasing interest and investment, the field of marine ecosystem restoration is just beginning to undergo synthesis. Therefore, the aim of this Research Topic is to bring together research contributions to help address this synthesis need, provide a spotlight for recent innovations, enhance our understanding of successful methods in marine ecosystem restoration and promote integration of ecological, sociological and engineering theory into restoration practices.

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
Trace metals play key roles in life - all are toxic above a threshold bioavailability, yet many are essential to metabolism at lower doses. It is important to appreciate the natural history of an organism in order to understand the interaction between its biology and trace metals. The countryside and indeed the natural history of the British Isles are littered with the effects of metals, mostly via historical mining and subsequent industrial development. This fascinating story encompasses history, economics, geography, geology, chemistry, biochemistry, physiology, ecology, ecotoxicology and above all natural history. Examples abound of interactions between organisms and metals in the terrestrial, freshwater, estuarine, coastal and oceanic environments in and around the British Isles. Many of these interactions have nothing to do with metal pollution. All organisms are affected from bacteria, plants and invertebrates to charismatic species such as seals, dolphins, whales and seabirds. All have a tale to tell.
