Book Description
Marine ecosystems are very productive and include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics. The biodiversity of some of these ecosystems is very rich and abundant, offering unique opportunities for high-yield production of proteinaceous material, which is a source of high-quality foods. Biodiversity is fundamental to sustaining marine ecosystem services, such as food security, maintenance of water quality, and recovery from perturbations, which are currently being threatened worldwide. The main threats to marine biodiversity are habitat loss, eutrophication, overexploitation, pollution by hazardous substances, introduction of non-native species, and other human activities. Efforts to reduce these pressures are essential for coastal water quality, recovery of ecosystem services, global food security, and ecosystem stability. Bioindicators are important tools to be used as early warning signals to detect the presence of natural and chemical stressors when monitoring and managing ecosystems and thus promoting ecosystem health. The protection of biodiversity is a major target of the European Union Marine Strategy Framework Directive, requiring an assessment of the status of biodiversity on the level of species, habitats, and ecosystems, including genetic diversity and the role of biodiversity in food web structure and functioning. The restoration of marine ecosystems can support the productivity and reliability of goods and services that the ocean provides to humankind to maintain ecosystem integrity and stability. Some of the goods produced by the marine ecosystem services are fish harvests, wild plant and animal resources, water, and services that provide recreation, tourism, breeding and nursery habitats, water transport, carbon sequestration, erosion control, and habitat provision. This book comprises six chapters that discuss the ecological, economic, and social roles of a variety of organisms, from primary producers to consumers, relating these roles with water quality and conservation of estuarine and marine ecosystems and thus the contribution to human health.

Book Description
What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

Book Description
With increasing interest in the field and its relevance in global environmental issues, Oceanography and Marine Biology: An Annual Review provides authoritative reviews that summarize results of recent research in basic areas of marine research, exploring topics of special and topical importance while adding to new areas as they arise. This volume, part of a series that regards the all marine sciences as a complete unit, features contributions from experts involved in biological, chemical, geological, and physical aspects of marine science. Including a full color insert and an extensive reference list, the text is an essential reference for researchers and students in all fields of marine science.

Book Description
Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.

Book Description
This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries.This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.
