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.

Ever-increasing interest in oceanography and marine biology and their relevance to global environmental issues create a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its founding by the late Harold Barnes more than 50 years ago. Its objectives are to consider, annually, the basic areas of marine research, returning to them when appropriate in future volumes; to deal with subjects of special and topical importance; and to add new subjects as they arise. The favourable reception and complimentary reviews accorded to all the volumes shows that the series is fulfilling a very real need. Volume 54 follows closely the objectives and style of the earlier volumes, continuing to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments. It is consistently among the highest ranking series in terms of impact factor in the marine biology category of the citation indices compiled by the Institute for Scientific Information/Web of Science.

A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.

This book tries to bridge the gap between science and environmental education by describing a set of projects, initiatives and field activities, which aim at raising awareness on the environment and encourage action. Via the descriptions of approaches, methods and projects, it shows how different organisations have been linking science with environmental education, the approaches used and the outcomes achieved. The various case studies guarantee that a special emphasis is given to practice - as opposed to a focus on the theory as has largely been the case in the past. This publication presents inputs from experienced science and environmental educators, drawing heavily from examples from Portugal. It will be a valuable tool for teachers, academics and practitioners as well as to students, who will find useful hints and advice on how to link science and environmental education, bearing in mind different contexts, realities and resources.

This GESAMP study presents a set of objectives, goals, methodologies and a checklist for assessment and communication of environmental risks which may be associated with coastal aquaculture. It is structured to improve risk communication and to ensure that risk assessment is a scientific exercise in predicting environmental change. A set of six case studies is also presented to illustrate the use of the environmental risk assessment methodologies. These examples of environmental interactions span a range of cultured species from fin fish to molluscs and shrimp.

Der stumme Frühling erschien erstmals 1962. Der Titel bezieht sich auf das eingangs erzählte Märchen von der blühenden Stadt, in der sich eine seltsame, schleichende Seuche ausbreitet … Das spannend geschriebene Sachbuch wirkte bei seinem Erscheinen wie ein Alarmsignal und avancierte rasch zur Bibel der damals entstehendenÖkologie-Bewegung. ZumerstenMal wurde hier in eindringlichem Appell die Fragwürdigkeit des chemischen Pflanzenschutzes dargelegt. An einer Fülle von Tatsachen machte Rachel Carson seine schädlichen Auswirkungen auf die Natur und die Menschen deutlich. Ihre Warnungen haben seither nichts von ihrer Aktualität verloren.

In diesem Buch berichten 95 Wissenschaftlerinnen und Wissenschaftler über ihre Forschung im Ozean und an den Küsten. Sie führen den Leser von den eisbedeckten Polarmeeren über die Nord- und Ostsee bis zu den Seegraswiesen, tropischen Mangroven und Korallenriffen. Die Beiträge veranschaulichen die Vielfalt der Lebensgemeinschaften zwischen Strand und Tiefsee. Das Größenspektrum der Organismen reicht von Walen und Fischen über Planktonkrebse und Muscheln bis zu Kieselalgen und Bakterien. Die globalen – vom Leben im Meer bestimmten – Stoffkreisläufe werden ebenso behandelt wie die molekularbiologischen Anpassungen der Mikroorganismen, und hier sind auch die größten methodischen Fortschritte zu verzeichnen. Zu den spannenden Themen der angewandten Meeresforschung gehören die Überfischung und die nachhaltige Nutzung der Meere, die Gefährdung durch Schad- und Nährstoffeinträge, die Einschleppen fremder Organismen und die Zerstörung von Lebensräumen. Vielfältig und bereits deutlich nachweisbar sind die Einflüsse des globalen Klimawandels auf das Leben im Meer. Forschungsschiffe, Unterwasser-Roboter, Gensonden und Datenbanken, aber auch mathematische Modelle und naturnahe Experimente sind wichtige Werkzeuge der Meeresbiologen. Exkurse über die Geschichte und Struktur der meeresbiologischen Forschung in Deutschland runden die Übersicht ab. In 48 selbständigen Beiträgen fügt sich die Vielfalt moderner, meeresökologischer Forschung zu einem faszinierenden Gesamtbild zusammen. Das Buch richtet sich an Lehrende und Lernende und an alle, die sich für das Meer und seine Bewohner, für modernes Ressourcenmanagement und marinen Naturschutz interessieren.
