The third edition of this bestselling text has been rigorously updated to reflect major new discoveries and concepts since 2011, especially progress due to extensive application of high-throughput sequencing, single cell genomics and analysis of large datasets. Significant advances in understanding the diversity and evolution of bacteria, archaea, fungi, protists, and viruses are discussed and their importance in marine processes is explored in detail. Now in full colour throughout, all chapters have been significantly expanded, with many new diagrams, illustrations and boxes to aid students' interest and understanding. Novel pedagogy is designed to encourage students to explore current high-profile research topics. Examples include the impacts of rising CO2 levels on microbial community structure and ocean processes, interactions of microbes with plastic pollution, symbiotic interactions, and emerging diseases of marine life. This is the only textbook addressing such a broad range of topics in the specific area of marine microbiology, now a core topic within broader Marine Science degrees. A Companion Website provides additional online resources for instructors and students, including a summary of key concepts and terminology for each chapter, links to further resources, and flashcards to aid self-assessment.

Cephalopods (octopus, squid, cuttlefish) are among the most intelligent invertebrates, with highly developed nervous systems which provide excellent model systems for investigating basic questions in neuroscience. Within the last five years, many of the powerful techniques of molecular biology and electrophysiology have been applied to cephalopods, with exciting results. In 32 chapters, this book provides a comprehensive overview of the functioning of the cephalopod nervous system, from the cellular level to their complex sensory systems, locomotion, learning, and social behavior. It will be of interest to both vertebrate and invertebrate neurobiologists, and by anyone interested in the basic principles that control neural function.

Since the advent of the electron microscope, there has been a dramatic increase in our understanding of the microalgae. With contributions from leading researchers from around the world, this book presents a completely up-to-date survey of the prymnesiophyte algae. Ubiquitous in their distribution--particularly as members of the marine phytoplankton--the prymnesiophyte algae has long been recognized for production of fish toxins and for its importance as geological markers via the preservation of their mineralized remains. But the Prymnesiophyta have achieved considerable notoriety in recent years not only because they have they been responsible for disastrous ichthyotoxic blooms in Scandinavian coastal waters, but because it now appears that their production of volatile sulphur compounds and calcifying mineralization may be adversely affecting our climate. This volume is the first book to bring together the scattered literature on this group and covers all the main aspects of Prymnesiophyte biology--including taxonomy, structure, ecology, biochemistry, origins, and evolution. Students and marine biologists studying algae, plankton, and ecology, as well as botanical microbiologists will want to read this important volume.

This comprehensive volume contains some sixty papers and reviews presented at the First International Symposium on Abalone Biology, Fisheries and Culture held in La Paz, Mexico. Introductory reviews in the book focus on the evolutionary origin, radiation and modern relationships of the genus Haliotis. Further papers review aspects of the reproductive process, larval energetics, mechanisms of larval settlement, and the ecology of settlement. Feeding deterrents and attractants, and the relation between food and growth are reviewed in a later section of authoritative papers. The natural mortality of abalone and its causes, predators and diseases are thoroughly reviewed. Several papers summarise information on the withering syndrome afflicting black abalone in California. A series of excellent papers and reviews then consider the problems of managing abalone fisheries. The models used are reviewed and examples given of the application of models to specific fisheries. Further papers provide new information on stock enhancement and the book concludes with case studies of the eight major abalone fisheries of the world with a review of the management of each. The book is divided into eight sections as follows: Part I -- Evolution and distributuion. Part II -- Physiology, genetics, reproduction. Part III -- Larval ecology and settlement. Part IV -- Feeding, growth. Part V -- Marketing, disease and predators. Part VI -- Fishery biology, modelling. Part VII -- Case studies of fisheries. Part VIII -- Culture.

Flagellated protozoa have become important in two biological disciplines. In evolutionary biology flagellates are critical to understanding the origins of eukaryotic cells and their diversification as protists and subsequently as plants, animals and fungi. Flagellated protozoa also play a key role in aquatic ecosystems, where they regulate bacterial numbers and control the remineralization of nutrients. The aim of this volume is to provide a synthesis of information on these organisms. Chapters deal with the organization, diversity, ecology, and maintenance of free-living flagellates. Each chapter is written by a recognized authority in his or her field. The book will be of interest to protozoologists, protistologists, evolutionary biologists, and ecologists dealing with aquatic or soil ecosystems.

Quantitative methods specifically tailored for the marine biologist

While there are countless texts published on quantitative methods and many texts that cover quantitative terrestrial ecology, this text fills the need for the special quantitative problems confronting marine biologists and biological oceanographers. The author combines common quantitative techniques with recent advances in quantitative methodology and then demonstrates how these techniques can be used to study marine organisms, their behaviors, and their interactions with the environment. Readers learn how to better design experiments and sampling, employ sophisticated mathematical techniques, and accurately interpret and communicate the results.
Most of this text is written at an introductory level, with a few topics that advance to more complex themes. Among the topics covered are plot/plotless sampling, biometrics, experimental design, game theory, optimization, time trends, modeling, and environmental impact assessments.
Even readers new to quantitative methods will find the material accessible, with plenty of features to engage their interest, promote learning, and put their knowledge into practice:
* One or more examples are provided to illustrate each individual quantitative technique presented in the text
* The accompanying CD-ROM features two multimedia programs, several statistical programs, help to run complex statistical programs, and additional information amplifying topics covered in the text
* References lead readers to additional information to pursue individual topics in greater depth
Quantitative Analysis of Marine Biological Communities, with its extensive use of examples, is ideal for undergraduate and graduate students in marine biology. Marine biologists, regardless of their level of experience, will also discover new approaches to quantitative analysis tailored to the particular needs of their field.

This volume offers contributions from leading experts in the biology of chaetognaths, or arrow worms--voracious carnivores which are exceptionally abundant in all the seas of the world. Until now there has been a lack of easily accessible information on this group, despite the fact that their vast numbers very likely render chaetognaths of major ecological significance in marine planktonic communities. This work is the first comprehensive survey. It deals with all aspects of chaetognath biology, including much recent and unpublished work. Two chapters are devoted to taxonomic relationships, two chapters cover morphology and anatomy, four chapters are concerned with physiology and behavior, three are devoted to ecology, and one chapter provides detailed information about the techniques necessary for studying the organism. The book will interest all marine biologists and zoologists working on plankton, along with invertebrate biologists, systematists, and advanced students of marine biology.

Lake Tanganyika, situated in the western rift system of East Africa, is the largest in volume of the African Great Lakes and the second deepest lake in the world. It is extremely ancient in comparison with most lakes. The aquatic flora and fauna are remarkable for their diversity and high degree of endemicity, as well as for the numbers of species and genera present. The lake has attracted international interest and much has been written about it. With its comprehensive bibliography, this book should provide a foundation of information that will be useful in further studies.

This and the companion volume describe and illustrate more than 2000 species, form selected protozoans to fishes, found in the coastal waters of the British Isles and north-western Europe. They cover all benthic habitats, from the intertidal zone to approximately 30 metres depth, and also includes representatives of estuarine and supralittoral faunas. Each major animal group is briefly introduced, with notes on the morphology, biology, and ecology of representative species, together with suitable techniques for their collection and study. Short bibliographies list the most important specialist literature for each group. Identification is facilitated by dichotomous keys, first to families, and then to genera or species. Short diagnostic accounts are given for each family and higher taxon; descriptions of all species treated are followed by notes on their ecological and geographical distribution. All species are illustrated by line drawings, with related species grouped together to facilitate comparisons. The two volumes comprise the most comprehensive account of the marine fauna of British and adjacent waters ever produced. It is intended as a bench work for both the professional and amateur marine biologist, as well as for undergraduate and postgraduate students. It is essentially a practical work; taxonomic and synonymic detail is deliberately kept to a minimum, with emphasis given to identification procedures.

A counterintuitive and compelling argument that existing laws already protect the entirety of our oceans-and a call to understand and enforce those protections. The world's oceans face multiple threats: the effects of climate change, pollution, overfishing, plastic waste, and more. Confronted with the immensity of these challenges and of the oceans themselves, we might wonder what more can be done to stop their decline and better protect the sea and marine life. Such widespread environmental threats call for a simple but significant shift in reasoning to bring about long-overdue, elemental change in the way we use ocean resources. In Future Sea, ocean advocate and marine-policy researcher Deborah Rowan Wright provides the tools for that shift. Questioning the underlying philosophy of established ocean conservation approaches, Rowan Wright lays out a radical alternative: a bold and far-reaching strategy of 100 percent ocean protection that would put an end to destructive industrial activities, better safeguard marine biodiversity, and enable ocean wildlife to return and thrive along coasts and in seas around the globe. Future Sea is essentially concerned with the solutions and not the problems. Rowan Wright shines a light on existing international laws intended to keep marine environments safe that could underpin this new strategy. She gathers inspiring stories of communities and countries using ocean resources wisely, as well as of successful conservation projects, to build up a cautiously optimistic picture of the future for our oceans-counteracting all-too-prevalent reports of doom and gloom. A passionate, sweeping, and personal account, Future Sea not only argues for systemic change in how we manage what we do in the sea but also describes steps that anyone, from children to political leaders (or indeed, any reader of the book), can take toward safeguarding the oceans and their extraordinary wildlife.

How did the elephant seal survive being driven to the brink of extinction in the nineteenth century? What variables determine the lifetime reproductive success of individual seals? How have elephant seals adapted to tolerate remarkable physiological extremes of nutrition, temperature, asphyxia, and pressure? Answering these questions and many more, this book is the result of the author's 50-year study of elephant seals. The chapters cover a broad range of topics including diving, feeding, migration and reproductive behavior, yielding fundamental information on general biological principles, the operation of natural selection, the evolution of social behavior, the formation of vocal dialects, colony development, and population changes over time. The book will be a valuable resource for graduate students and researchers of marine mammal behavior and reproductive life history as well as for amateur naturalists interested in these fascinating animals.

What lies beneath the surface of the ocean has mystified humankind for millennia. We have explored more of the surface of the Moon than we have of the deep sea. From vampire squid to giant spider crabs, and from hydrothermal vents to bioluminescence, its watery depths are both fascinating and terrifying. Deep Water explores, through spectacular images and expert text, how this unique habitat came into being, what lives there and why, how it has evolved and what the future will bring for this dark and mysterious environment.

This excellent second edition of Fisheries Biology, Assessment and Management, has been fully updated and expanded, providing a book which is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. In the same way that excessive hunting on land has threatened terrestrial species, excessive fishing in the sea has reduced stocks of marine species to dangerously low levels. In addition, the ecosystems that support coastal marine species are threatened by habitat destruction, development and pollution. Open access policies and subsidised fishing are placing seafood in danger of becoming a scarce and very expensive commodity for which there is an insatiable demand. Positive trends include actions being taken to decrease the incidental catches of non-target species, consumer preferences for seafood from sustainable fisheries, and the establishment of no-take areas that provide refuges for marine species. But there is an urgent need to do more. Because there is an increasing recognition of the need to manage ecosystems as well as fish stocks, this second edition of this bestselling text book includes an additional chapter on marine ecology. Chapters on parameter estimation and stock assessment now include step-by-step instructions on building computer spreadsheet models, including simulations with random variations that realistically emulate the vagaries of nature. Sections on ecosystem management, co-management, community-based management and marine protected areas have been expanded to match the increased interest in these areas. Containing many worked examples, computer programs and numerous high quality illustrations, Fisheries Biology, Assessment and Management, second edition, is a comprehensive and essential text for students worldwide studying fisheries, fish biology, aquatic and biological sciences. As well as serving as a core text for students, the book is a superb reference for fisheries and aquatic researchers, scientists and managers across the globe, in both temperate and tropical regions. Libraries in all universities where fish biology, fisheries, aquatic sciences and biological sciences are studied and taught will need copies of this most useful new edition on their shelves.

Echinoderms elaborate a calcite skeleton composed of numerous plates with a distinct microstructure (stereom) that can be modelled into different shapes thanks to the use of a transient amorphous calcium carbonate (ACC) precursor phase and the incorporation of an intraorganic matrix during biomineralization. A variety of different types of stereom microarchitecture have been distinguished, each of them optimized for a specific function. For instance, a regular, galleried stereom typically houses collagenous ligaments, whereas an irregular, fine labyrinthic stereom commonly bears muscles. Epithelial tissues, in turn, are usually associated with coarse and dense stereom microfabrics. Stereom can be preserved in fossil echinoderms and a wide array of investigating methods are available. As many case studies have shown, a great deal of important paleobiological and paleoecological information can be decoded by studying the stereom microstructure of extinct echinoderms.

Aquatic systems exhibit incredible diversity - from mountain streams to deep oceans, from lakes and ponds to the estuaries that link river and sea. Despite their distinct characters, however, these systems share common properties and, at the level of ecology, are not all that different after all. But how can this be? Ecology of Aquatic Systems brings together coverage of freshwater and marine systems to illustrate the principles and properties that unify aquatic systems. Using examples drawn from a wide geographical range, the book presents a broad survey of the field that acts as the ideal foundation for further study. Opening with a review of the different types of aquatic system and their interconnected nature, and the diversity of life within aquatic systems, the book goes on to explore the key types of aquatic habitat, emphasising the ecological themes that pervade each system. Written with students in the centre of the frame, Ecology of Aquatic Systems retains the succinct, lucid style for which the first edition was praised, and includes cross-references throughout, a substantial glossary, and extensive index, to help readers engage with, and fully understand, the material presented. With the global importance of aquatic systems becoming more apparent - and the need for effective management of these systems becoming increasingly clear - there has never been a more important time for students to fully grasp the fundamentals of aquatic systems. Ecology of Aquatic Systems is the ideal course companion to achieve this goal.

Essential Fish Biology provides an introductory overview of the functional biology of fish and how this may be affected by the widely contrasting habitat conditions within the aquatic environment. It describes the recent advances in comparative animal physiology which have greatly influenced our understanding of fish function as well as generating questions that have yet to be resolved. Fish taxa represent the largest number of vertebrates, with over 25,000 extant species. However, much of our knowledge, apart from taxonomy and habitat descriptions, has been based on relatively few of them , usually those which live in fresh water and/or are of commercial interest. Unfortunately there has also been a tendency to base our interpretation of fish physiology on that of mammalian systems, as well as to rely on a few type species of fish. This accessible textbook will redress the balance by using examples of fish from a wide range of species and habitats, emphasizing diversity as well as recognizing shared attributes with other vertebrates.

Wetlands - swamp, marsh, bayou, tundra and bog - are places that are rarely visited and often misunderstood but they have, in fact, conspicuous roles in the physical, biological and cultural geography of the world.? They are intrinsically beautiful environments where one may see the natural and essential values in the interaction of water, soil, vegetation, wildlife, and humans.? Wetlands occur at the confluence of unique terrestrial, hydrological and climatic conditions that give rise to some of the most biodiverse regions of the world.? They also play vital roles in the cycling and storage of key nutrients, materials and energy through the Earth's system.

A complete study of wetland environments requires the assessment of their physical and biological attributes, properties and functions of these ecosystems, and the economic, political and social aspects that mediate their use globally.? A systems approach is taken throughout this book which emphasizes the interactions between these elements of wetland ecosystems.? Moreover, selected case studies from across the world are used to illustrate wetland characteristics and circumstances.?

This book is intended to foster a greater awareness and appreciation of wetlands, promote a culture of conservation and wise management, and spread the knowledge that wetlands are important, indeed crucial, elements of the global environment.? Our attempts to understand, manage and enhance wetlands in the twenty-first century are part of the larger effort to maintain a sustainable Earth.

The image most of us have of whalers includes harpoons and intentional trauma. Yet eating commercially caught seafood leads to whales' entanglement and slow death in rope and nets, and the global shipping routes that bring us readily available goods often lead to death by collision. We-all of us-are whalers, marine scientist and veterinarian Michael J. Moore contends. But we do not have to be. Drawing on over forty years of fieldwork with humpback, pilot, fin, and in particular, North Atlantic right whales-a species whose population has declined more than twenty percent since 2017-Moore takes us with him as he performs whale necropsies on animals stranded on beaches, in his independent research alongside whalers using explosive harpoons, and as he tracks injured whales to deliver sedatives. The whales' plight is a complex, confounding, and disturbing one. We learn of existing but poorly enforced conservation laws and of perennial (and often failed) efforts to balance the push for fisheries profit versus the protection of endangered species caught by accident. But despite these challenges, Moore's tale is an optimistic one. He shows us how technologies for rope-less fishing and the acoustic tracking of whale migrations make a dramatic difference. And he looks ahead with hope as our growing understanding of these extraordinary creatures fuels an ever-stronger drive for change.

Oceanographers and the Cold War is about patronage, politics, and the community of scientists. It is the first book to examine the study of the oceans during the Cold War era and explore the international focus of American oceanographers, taking into account the roles of the US Navy, US foreign policy, and scientists throughout the world. Jacob Darwin Hamblin demonstrates that to understand the history of American oceanography, one must consider its role in both conflict and cooperation with other nations. Paradoxically, American oceanography after World War II was enmeshed in the military-industrial complex while characterized by close international cooperation. The military dimension of marine science--with its involvement in submarine acoustics, fleet operations, and sea-launched nuclear missiles--coexisted with data exchange programs with the Soviet Union and global operations in seas without borders. From an uneasy cooperation with the Soviet bloc in the International Geophysical Year of 1957-58, to the NATO Science Committee in the late 1960s, which excluded the Soviet Union, to the US Marine Sciences Council, which served as an important national link between scientists and the government, Oceanographers and the Cold War reveals the military and foreign policy goals served by US government involvement in cooperative activities between scientists, such as joint cruises and expeditions. It demonstrates as well the extent to which oceanographers used international cooperation as a vehicle to pursue patronage from military, government, and commercial sponsors during the Cold War, as they sought support for their work by creating "disciples of marine science" wherever they could.

"Conus" is the largest genus of animals in the sea, occurring throughout the world's tropical and subtropical oceans and contributing significantly to marine biodiversity. The shells of these marine mollusks are prized for their amazing variety and extraordinary beauty. The neurotoxic venoms they produce--injected by a hollow, harpoon-like tooth into prey animals that are then paralyzed and swallowed whole--have a range of pharmaceutical applications, from painkillers to antidepressants. This beautifully illustrated book identifies 53 valid species of the southeastern United States and the Caribbean, a region that supports a diverse but taxonomically challenging group of "Conus." Introductory chapters cover the evolution and phylogeny of the genus, and notes on methodology are provided. Detailed species accounts describe key identification features, taxonomy, distribution, ecology, toxicology, life history, and evolutionary relationships. The book includes more than 2,100 photos of shells on 109 splendid color plates; more than 100 additional photos, many depicting live animals in color; and 35 color distribution maps.Identifies 53 valid species--the first reassessment of western Atlantic "Conus" in more than seventy yearsFeatures more than 2,100 photos of shells on 109 color platesBlends the traditional shell-character approach to identification with cutting-edge shell and radular tooth morphometrics and molecular genetic analysesIncludes color images of live animals as well as color distribution maps
