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.

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.

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.

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.

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.

On dry land, most organisms are confined to the surface, or at most to altitudes of a hundred meters - the height of the tallest trees. In the oceans, though, living space has both vertical and horizontal dimensions: with an average depth of 3,800 meters, the oceans offer 99 percent of the space on Earth where life can develop. And the deep sea, which has been immersed in total darkness since the dawn of time, occupies 85 percent of ocean space, forming the planet's largest habitat. Yet, these depths abound with mystery. The deep sea is mostly uncharted - only about 5 percent of the seafloor has been mapped with any reasonable degree of detail - and we know very little about the creatures that call it home. Current estimates about the number of species yet to be found vary between ten and thirty million. The deep sea no longer has anything to prove; it is without doubt Earth's largest reservoir of life. Combining the latest scientific discoveries with astonishing color imagery, "The Deep" takes readers on a voyage into the darkest realms of the ocean. Revealing nature's oddest and most mesmerizing creatures in crystalline detail, "The Deep" features more than two hundred color photographs of terrifying sea monsters, living fossils, and ethereal bioluminescent creatures, some photographed here for the very first time. Accompanying these breathtaking photographs are contributions from some of the world's most respected researchers that examine the biology of deep-sea organisms, the ecology of deep-sea habitats, and the history of deep-sea exploration. An unforgettable visual and scientific tour of the teeming abyss, "The Deep" celebrates the incredible diversity of life on Earth and will captivate anyone intrigued by the unseen - and unimaginable - creatures of the deep sea.

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.

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 is the largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. Schiel and Foster's scholarly review and synthesis take the reader from Darwin's early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The authors furnish a comprehensive discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change. This volume promises to be the definitive treatise and reference on giant kelp and its forests for many years, and it will appeal to marine scientists and others who want a better appreciation and understanding of these wondrous forests of the sea.

Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we've seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutants and the many ways they can come to harm our environment and our bodies.
In Marine Pollution: What Everyone Needs to Know, Judith Weis covers marine pollution from many different angles, each fascinating in its own right. Beginning with its sources and history, the book describes in detail each common pollutant, why exactly it is harmful, why it may draw controversy, and how we can prevent it from destroying our aquatic ecosystems. Weis discusses topics like what actually happened with the Exxon Valdez, and why Harmful Algal Blooms are a serious concern. Later chapters will discuss pollutants that are only now surfacing as major threats, such as pharmaceuticals, personal care products, and metal nanoparticles, and explain how these can begin in the water and progress up the food chain and emerge in human bodies. The book's final section will discuss the effects of climate change and acidification on marine pollution levels, and how we can reduce pollution at the local and global levels.

Touching This Leviathan asks how we might come to know the unknowable--in this case, whales, these animals so large yet so elusive, revealing just a sliver of back, a glimpse of a fluke, or, if you're lucky, a split-second breach before diving away. It's a pressing question, given how frequently whales are in the news: Japan just withdrew from the International Whaling Commission's ban on whaling; the Makah Tribe seeks to resume hunts; in 2019 there was a rash of dead gray whales along the west coast (some 200 of them); in 2018, an orca attracted international attention when she pushed her dead calf through the water 17 days before finally letting go. But other whale books sit in disciplinary silos: the history books, the science books, the literary books. There's no conversation between them, which is where Touching This Leviathan intervenes. Drawing upon biology, theology, local history, literary studies, environmental studies, and composition theory, Touching This Leviathan is necessarily interdisciplinary: literary nonfiction that gestures toward science and literary criticism as it invites readers into the belly of the whale.
