Book Description
This book addresses the question of what determines species richness in tropical animals by comparing and contrasting the communities of the five major classes of vertebrates in two environments considered to be the most species-rich on Planet Earth - the coral reef and the rainforest. All the contributors were asked to examine how so many species could coexist in such communities and to discuss the ways species assemblages might have evolved over time. Because the coauthors are ecologists, emphasis is quite naturally placed on the first of these two questions, and the factors contributing to the maintenance of a-diversity are discussed at length. However, the question of the very origin of species richness can never be eluded, though it is more an evolutionary problem than an ecological one; it has therefore also been given some attention occasionally. Since we believe that long-term descriptive data and extended field experience are absolutely essential to formulate meaningful questions and pro pose realistic models, contributors were selected on the basis of their prolonged field practice; all of them actually spent years in the field and/or participated in long-term research programs. The present volume has its origin in a symposium held on August 15, 1986 at Syra cuse, New York, during the Fourth International Congress of Ecology.

Book Description
Coral reefs are among Earth's most diverse, productive, and beautiful ecosystems, but until recently, their ecology and the means to manage them have been poorly understood and documented. In response to the inadequate information base for coral reefs, this book reviews the ecological and conservation status of coral reefs of the Western Indian Ocean, bringing together presentations of the region's leading scientists and managers working on coral reefs.Coral Reefs of the Indian Ocean: Their Ecology and Conservation starts with a general overview of the biogeography of the region and a historical account of attempts to conserve this ecosystem. It goes on to describe the state of the reefs in each of the countries with coral reefs, and it concludes with a series of management case studies.The book also summarizes most of the existing ecological information on reefs in this region and efforts at management, making it useful for students, teachers, and investigators interested in tropical or marine ecology, conservation biology and management, and environmental sciences.

Book Description
This landmark publication collates information and studies on the use of estuaries, and specific habitats within them, as nursery, feeding and refuge areas, and migration routes of marine and other fish, many of which are of commercial and conservation importance. The editors and authors of the book have carefully compiled a huge wealth of information from the work of 18 organizations across 11 countries, providing a unique collection of data never before brought together within the covers of one book. Chapters within this exceptional publication cover habitat use by fishes, recruitment and production in estuaries, links between fish and other trophic levels, endangered and rare species, estuarine development and restoration, environmental quality of estuaries and the management of estuarine fishes. The book notably contains extensive chapters on field methods and data analysis. Fishes in Estuaries is an essential tool and reference source for fisheries and environmental managers, fish biologists, environmental scientists, aquatic ecologists and conservation biologists. Libraries in all universities and research establishments where biological sciences are studied and taught should have copies of this book on their shelves, as should personnel employed in regulatory and consultant capacities, such as within rivers authorities, environment agencies and fish and wildlife departments. Comprehensive coverage of commercially exploited species. Internationally known and respected contributors. Multi-contributor approach providing very detailed coverage. Estuaries are a vitally important ecosystem.

Book Description
Das zweibändige Werk Fish and Fisheries in Estuaries: A Global Perspective enthält eine Darstellung des aktuellen Wissensstandes über Fische in Ästuaren. In Beiträgen von mehr als fünfzig international anerkannten Forschern und Experten für Ichthyologie in Ästuaren präsentiert dieses wegweisende Übersichtswerk die Themen Fischbestände und funktionelle Gruppen, Rekrutierung und Produktion in Ästuaren, Ernährungsökologie und trophische Dynamik, Erhaltung von Fischen in Ästuaren und viele mehr. In dreizehn ausführlichen Kapiteln werden die wichtigsten Aspekte zu Fischen und Fischerei in Ästuaren rund um die Welt beschrieben. Es wird die Biologie der Fische in Ästuargewässern und ihre Verbindung zu den dortigen Ökosystemen betrachtet, und es wird analysiert, wie sich die menschengemachte Industrialisierung und globale Ereignisse wie der Klimawandel auf einheimische und andere Arten auswirken. Weitere Themen sind die Vielfalt der Lebensräume, das Verhalten von Fischen bei der Nahrungssuche, Instrumente und Modelle der Umwelttechnik, Gefahren und Risiken für Fische und Fischerei in Ästuaren sowie die Gesundheit der Umwelt in Ästuaren. Dieses maßgebliche Referenzwerk enthält detaillierte Informationen über die Biologie und Ökologie von Fischen und Fischerei in Ästuaren und bietet außerdem: * Eine Betrachtung aktueller Ansätze und künftiger Forschungsrichtungen, die darauf abzielen, ein Gleichgewicht zwischen der Nutzung und der Erhaltung von Fischen in Ästuaren zu erreichen * Eine Erörterung der Umweltqualitätsziele sowie der nachhaltigen Fischerei und Bewirtschaftung der Ästuare * Eine Untersuchung, wie sich die zunehmende Nutzung von Ressourcen wie Nahrung, Raum und Wasser durch den Menschen auf die Fischerei in den Ästuaren auswirkt * Zahlreiche internationale Fallstudien zum Fischereimanagement, zu bedrohten Arten, zur Sanierung von Ästuaren, zur Fortpflanzung und Ontogenese und weiteren Themen * Eine Darstellung der Studien- und Probenahmeverfahren, der Feldausrüstung sowie der Verarbeitung, Analyse und Interpretation der Daten Das Werk Fish and Fisheries in Estuaries: A Global Perspective ist ein unverzichtbares Hilfsmittel und eine Referenzquelle für Fischbiologen, Fischereiwissenschaftler, Ökologen und Umweltwissenschaftler, Gewässerökologen, Naturschutzbiologen sowie Studierende der höheren Semester und Dozenten im Bereich Fischbiologie und Fischerei.
