The Ebro is a typical Mediterranean river characterized by seasonal low flows and extreme flush effects, with important agricultural and industrial activity that has caused heavy contamination problems. This volume deals with soil-sediment-groundwater related issues in the Ebro river basin and summarizes the results generated within the European Union-funded project "AquaTerra." The following topics are highlighted: Hydrology and sediment transport and their alterations due to climate change, aquatic and riparian biodiversity in the Ebro watershed, occurrence and distribution of a wide range of priority and emerging contaminants, effects of chemical pollution on biota and integration of climate change scenarios with several aspects of the Ebro s hydrology and potential impacts of climate change on pollution. The primary objective of the book is to lay the foundation for a better understanding of the behavior of environmental pollutants and their fluxes with respect to climate and land use changes."
The first edition of the widely praised Marine Protected Areas for Whales, Dolphins and Porpoises, published in 2005, led to numerous new marine protected area proposals and a number of notable conservation successes around the world. In this completely revised and expanded second edition, new developments in the Mediterranean, Caribbean and Pacific are described, as well as future directions for High Seas protection. New sections show how to design and manage Marine Protected Areas (MPA's) in an ever noisier ocean subject to climate change, increased shipping and hydrocarbon exploration. The process of protected area creation for cetaceans has been accelerated and more than 200 exciting new places are detailed in this edition. This book provides a route map for MPA managers, as well as countries, to meet the ambitious targets for highly protected MPA networks by 2012 and 2020. Marine Protected Areas for Whales, Dolphins and Porpoises is a key conservation tool and a springboard for worldwide change in human attitudes toward the world ocean where all life originated and where the majority of life on Earth still lives.
From the author of the international Bestseller Breath Covering a diving championship in Greece on a hot and sticky assignment for Outside magazine, James Nestor discovered free diving. He had stumbled on one of the most extreme sports in existence: a quest to extend the frontiers of human experience, in which divers descend without breathing equipment, for hundreds of feet below the water, for minutes after they should have died from lack of oxygen. Sometimes they emerge unconscious, or bleeding from the nose and ears, and sometimes they don't come up at all. The free divers were Nestor's way into an exhilarating and dangerous world of deep-sea pioneers, underwater athletes, scientists, spear fishermen, billionaires and ordinary men and women who are poised on the brink of some amazing discoveries about the ocean. Soon he was visiting the scientists who live 60ft underwater (and are permanently high on nitrous dioxide), swimming with the notorious man-eating sharks of Reunion and descending thousands of feet in a homemade submarine. And on the way down, he learnt about the amazing amphibious reflexes activated in the human body under deep-water conditions, why dolphins were injected with LSD in an attempt to teach them to talk, and why sharks like AC/DC. The sea covers seventy per cent of Earth's surface, and still contains answers to questions about the world we are only beginning to ask: Deep blends science and adventure to uncover its amazing secrets.
Estuaries exist along the edge of the oceans and seas, and are char acterized by the dilution of sea water by inflowing fresher waters. The motion and interaction of these two types of water (fresh and salt water) determine the salinity distribution within the estuary and that, in turn, affects the organisms residing there. The purpose of this vol ume is to review the status of our understanding of estuarine circu lation and how the circulation patterns affect living and nonliving resources in estuaries. For many years, the primary paradigm for estuarine circulation was the two-layered net or nontidal gravitational circulation pattern first proposed by Dr. Donald Pritchard in his studies of the James River estuary. During the last decade or so, research has focused on the many variations about this theme and the factors that control the transport processes. Many of these aspects are covered in the initial papers in this volume. Water movement, of course, is of interest be cause it transports marine organisms, sediments, and pollutants. Es tuarine circulation has a significant effect on estuarine food chains, and on the distribution and abundance of organisms, such as the American oyster, that are freely transported by the currents during larval stages. The intent is to bring together many of these topics in a single volume. This volume is dedicated to Dr. Donald W."
Reflecting increased interest in the field and its relevance in global environmental issues, Oceanography and Marine Biology: An Annual Review, Volume 47 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. These features along with the inclusion of a full color insert and an extensive reference list, make the text an essential reference for researchers and students in all fields of marine science.
The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http: //www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive."
This volume contains the Proceedings of the Third International Conference on Copepoda, held at the British Museum (Natural History) in London during August 1987. The central theme of the conference was the biology of marine planktonic copepods, although the scientific programme was extremely varied reflecting the wide range of life styles adopted by copepods. The three invited symposia held during the conference focussed attention on particular topical areas of research within the field of marine plankton, and also provided reviews of chosen aspects of copepod biology. These symposia were highly successful. The papers they contained were both informative and stimulating and they bring to this volume a lasting significance. Each symposium was organised by its chairman; Bruce Frost (University of Washington) decided on the balance of topics, selected the speakers and introduced the session on 'The biology and taxonomy of Calanus', Roger Harris (Marine Biological Association) performed the same vital role for 'Experimental studies: rate processes in field populations of planktonic copepods', and Howard Roe (Institute of Oceanographic Sciences) for 'Oceanic and deep-sea copepods'. The impact of these papers will be much enhanced by the large number of high quality contributed and poster papers on marine plankton and by the invited review of 'Copepod luminescence' by Peter Herring (Institute of Oceano graphic Sciences). The fascinating review of 'Copepod eyes' by Mike Land FRS (University of Sussex) is not published here."
The mangrove, seagrass and coral reef ecosystems are of paramount ecological importance but have already undergone great degradation, which is advancing at an alarming rate. If present trends continue, the natural resource basis of the economy and ecology of tropical coastal regions will soon be ruined. This was the unanimous conclusion of the 110 scientists from 23 countries who gathered in Mombasa, Kenya, for a Symposium on the ecology of these ecosystems. Mangrove forest systems yield large amounts of fish, crabs, prawns and oysters. They are also valuable sources of fuelwood, timber, tannin and other natural products. Their non-marketable value is of equal importance: stabilization of the coastline, an indispensable nursery ground for numerous marine species with commercial value, a natural filter maintaining the clarity of nearshore water, a home for resident and migratory birds and other wildlife. Many of the true mangrove flora and fauna are now endangered by the clearing of the mangroves. It has been shown that in many countries between 25 and 100% of the mangrove forest has been destroyed alraedy in the last twenty years. The international scientific assembly concluded that much can be done to stop the degradation of these damaged ecosystems and to rehabilitate them. But new techniques must be found to use them on a sustainable basis for long-term economic return and for the well-being of coastal human settlements and a healthy environment.
The Baltic Sea and its coastal zones have been intensively utilised for centuries. Settlements, industry, fisheries and trade are still concentrated in the coastal zones. Concurrently, the coast is a web of sensitive and highly valuable ecosystems which suffer from ongoing degradation. Increasing demands and pressures on coastal ecosystems require integrated coastal zone management. This book reflects the current state and problems of coastal ecosystems in the entire Baltic region, highlighting obstacles and future solutions for integrated management.
Based on research in Bolinao, this book assesses the importance of small-scale disturbance by burrowing shrimps. It covers the distribution of burrowing shrimp disturbance, the behavior of the snapping shrimp Alpheus macellarius in situ and as observed from tank experiments, and the effects of short-term burial and leaf clipping on the growth patterns of the dominant seagrass Thalassia hemprichii. The book examines the role of bioturbation by burrowing shrimps in seagrass meadows, foraging strategies of A. macellarius and its mutualistic symbiosis with Cryptocentrus spp., shrimp disturbance and T. hemprichii, and small-scale disturbance and large-scale dynamics.
The nemerteans are a fascinating, common and often locally abundant group of invertebrates, yet for long have attracted the attention of only a handful of scientists. In recent years, however, increasing numbers of people have developed diverse research interests in the group with the result that our knowledge of these worms has rapidly advanced. Clearly there is a need for a regular series of international meetings where individuals working on these animals can meet to exchange ideas, review developments concerning nemertean biology and freely discuss future proposals. The first such meeting was held in Philadelphia during December 1983. Twenty-seven scientists from eight countries participated in the Second International Meeting on Nemertean Biology, held at the Tjarno Marine Biological Laboratory, Sweden, 11-15 August 1986. The meeting was divid ed into five sessions: two dealt with ecological studies, two with nemertean taxonomy, and the final session covered aspects of general biology. A total of 26 papers was presented; four, by N. Anadem, G. Berg, 1. Bierne, and 1.M. TurbeviIIe, were for different reasons not submitted for inclusion in this volume. Three additional presentations were made on behalf of B. Kulikova, E. N. WiIImer, and Z. Yin, all of whom were unable to participate in the meeting.
Islands are special because they promote unique forms of life, and large proportions of the species they hold are found nowhere else on Earth. The mammals of the South-west Pacific are no exception, with many distributed only across single islands or archipelagos. Mammals of the South-west Pacific details the natural history for more than 180 species of marsupials, bats and rodents from 24 Pacific nations and territories. Species profiles are accompanied by distribution maps, illustrations and photographs – many being the first images ever captured for the species. By combining available knowledge with unpublished data collected over years of field work, Mammals of the South-west Pacific forms a definitive guide to the mammals from this region.
This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable re sources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem."
Ever-increasing interest in oceanography and marine biology and its relevance to global environmental issues creates a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has answered this demand since its founding by the late Harold Barnes more than forty years ago. Its objective is an annual consideration of basic areas of marine research, dealing with subjects of special or immediate importance, adding new subjects as they arise. The volumes maintain a unified perspective on the marine sciences. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. This essential reference text for researchers and students in all fields of marine science finds a place in libraries of marine stations and institutes, as well as universities. It consistently ranks among the highest in impact factors for the marine biology category of the citation indices compiled by the Institute for Scientific Information. Volume 42 contains analysis on convective chimneys in the Greenland Sea, spawning aggregations of coral reef fishes, exopolymers (EPS) in aquatic systems, the marine insect Halobates, and much more.

The book aims to present the current developments in select areas of biotechnology of aquatic animals, covering relevant information from the different fields. The book is a comprehensive set of reviews of our existing knowl-edge in biotechnology of aquatic animals. It is written principally as a comprehen-sive reference for students and teachers, as also offers a predictive challenging re-sources for researchers.
The marine environment has been, and continues to be, a fruitful source of novel chemical compounds that are not found in terrestrial and freshwater organisms. Many of these substances show potential biomedical applications, which could lead to development of new pharmaceutical products. Research on the utilization of natural products from marine organisms is growing by leaps and bounds; one important reason why being that, investigators, through new diving technologies, are becoming able to explore at greater depths. Studies of these marine natural products include investigations of neuronal membrane-active toxins, ion channel blockers, antitumor and antiviral agents, and anti-inflammatory molecules. This volume is the sixth in the ongoing series.
The extraordinary ability of dolphins to echolocate has fascinated scientists and the public since its discovery in the late 1950's. This is the first book to summarize modern research in this area, and presents a broad synthesis of this very interdisciplinary subject. The author is an internationally-recognized expert on dolphin sonar and is thus in a unique position to bring together research on the physiological, mathematical and engineering aspects of the subject. Of interest to auditory researchers, electrical engineers, acoustical physicists, and mammalian physiologists.
'A rewarding glimpse of another world' THE GUARDIAN Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet, and they have fascinating tales to tell. Spirals in Time charts the course of shells through history, from the first jewelry and the oldest currencies through to their use as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. In this book, Helen Scales leads us on a journey into the realm of these undersea marvels. She goes in search of everything from snails that 'fly' underwater to octopuses accused of stealing shells and giant mussels with golden beards. Shells are also bellwethers of our impact on the natural world. The effects of overfishing and pollution are, of course, serious concerns, but perhaps more worrying is ocean acidification, which causes shells to simply melt away. Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.

This volume is taken from an ecological study of wetlands undertaken in northern Lake Victoria (East Africa) between 1993 and 1996 with the major aim of characterizing shallow vegetation-dominated interface habitats, and evaluating their importance for fish, in particular, for the Nile tilapia.
Echinoderms are now considered as a biological and geological model that underlies researches of primary importance. The extent of the contributions made by the International Echinoderm Conferences to various fields of research is attested by the scope covered by presentation at the international conferences. These proceedings contain the complete papers or abstracts of all the presentations and posters presented at the eighth International Echinoderm Conference, held in Dijon, France in September, 1994. Coverage includes: general; extinct classes; crinoids; asteroids; ophiuroids; holothuroids; and echinoids.
Marine biology has always played an important role in biological research, being at the origin of many key advances. To a certain extent, the influence of marine biology on the biological sciences was overshadowed over a period of several years by the remarkable advances that were made using powerful model organisms from terrestrial environments. This situation is now changing again, however, due primarily to spectacular developments in genomic methodologies that have significantly accelerated research in a broad spectrum of marine biology disciplines ranging from biodiversity to developmental biology to biotechnology. The data generated by marine genomics projects have had an impact on questions as diverse as understanding planetary geochemical cycles, the impact of climate change on marine fauna and flora, the functioning of marine ecosystems, the discovery of new organisms and novel biomolecules, and investigation of the evolution of animal developmental complexity. This book represents the first attempt to document how genomic technologies are revolutionising these diverse domains of marine biology. Each chapter of this book looks at how these technologies are being employed in a specific domain of marine research and provides a summary of the major results obtained to date. The book as a whole provides an overview of marine genomics as a discipline and represents an ideal starting point for exploring this rapidly developing domain.
This volume provides a refereed selection of the proceedings of the 31st European Marine Biology Symposium, held in St. Petersburg, Russia, in September 1996. State-of-the-art reviews and studies on adaptational processes in marine organisms such as adaptations to fluctuations in salinity, temperature, oxygen and pollutants which are reflected in different types of ecophysiological responses and interactions of marine organisms, including predation, parasitism, intraspecific competition and epibiosys were presented at the symposium proceedings. Research from both eastern and western Europe contributed to this project and during the symposium differences in scientific approaches and views between these two groups became apparent. The contents of this volume reflect these differences. Researchers and students in marine biology as well as those involved in coastal management and environmental studies will find this volume of interest.
This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic rev1s10n of any group undertaken, although recommendations for such revisions are included where appropriate, and probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user of the key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number of species. This has already been done for the order Collembola. |
