Marine sediments dominate the global seabed, creating the largest ecosystem on earth. Seafloor biodiversity is a key mediator of ecosystem functioning, yet critical processes are often excluded from global biogeochemical budgets or simplified to black boxes in ecosystem models. This accessible textbook provides an ideal point of entry into the field, providing basic information on the nature of soft-sediment ecosystems, examples of how and why we research them, the new questions these studies inspire, and the applications that ultimately benefit society. While focussing on coastal habitats (<200m depth) to emphasize process-based experimental studies, it is relevant to the full range of marine sedimentary habitats. The authors describe the interactions between marine organisms and their physical and chemical environment, demonstrating the need for carefully designed research programs and providing the basic steps required to formulate sound ecological questions before applying them to empirical studies of real-world ecosystems. The book reveals the connections between different system components and drivers of change, examining how we can develop knowledge on the biodiversity and functioning of soft sediments and apply it to a better understanding of ecosystem change, human impacts, and effective restoration. Ecology of Coastal Marine Sediments is intended for advanced undergraduate and graduate students who have completed a general ecology course but received no further training in marine science. It will also be useful to both professional researchers and resource managers in marine ecology and environmental science who seek a compact and authoritative introduction to sediment ecology.
Since 1970, the Caribbean has lost half of its coral reefs, an ominous and accelerating phenomenon that extends around the world. Today's remaining coral reefs - still a source of endless discovery and mystery for scientists - are at risk of disappearing by century's end. Beyond the unfathomable heartbreak of the loss of such exquisite beauty from the earth's surface, coral's loss represents the annual loss of billions of dollars from the global economy and the end of a way of life for billions that depend on these ecosystems. Marine scientist and conservation leader David E. Guggenheim has had a front-row seat to this disaster. But when he began a new chapter of his career in Cuba, he found something completely unexpected: hope. After years and years of watching reefs deteriorate, Guggenheim was astonished to come face-to-face with Cuba's remarkably healthy coral reefs overflowing with fish and other life - ocean ecosystems that appear healthier than those he first encountered as a teenager more than four decades prior. Living Time Machine reveals the hidden potential that Cuba's reefs may contain for the reefs of the world. Which begs the question: why are Cuba's ocean waters so healthy? The answer is deeply intertwined with the country's extraordinary and singularly unique history, from its dramatic political past to its world-class environmental protections influenced by an unlikely partner, Captain Jacques Cousteau. The result is that while the past 60 years have seen the worst decline in ocean health in human history, Cuba's oceans and coral reefs remain remarkably healthy, a living laboratory never-before-seen by this generation of scientists. The author's account includes interviews with colleagues, scientists, policymakers, and his own decades-long experience as an American working in Cuba with local marine scientists to study and protect its coastal waters and coral reef ecosystems. Living Time Machine tells the story of the demise of the world's ocean ecosystems, the hard work of those desperately trying to save it, and an unexpected beacon of hope from an island full of mystery and surprises.
The hadal zone represents one of the last great frontiers in marine science, accounting for 45% of the total ocean depth range. Despite very little research effort since the 1950s, the last ten years has seen a renaissance in hadal exploration, almost certainly as a result of technological advances that have made this otherwise largely inaccessible frontier, a viable subject for research. Providing an overview of the geology involved in trench formation, the hydrography and food supply, this book details all that is currently known about organisms at hadal depths and linkages to the better known abyssal and bathyal depths. New insights on how, where and what really survives and thrives in the deepest biozone are provided, allowing this region to be considered when dealing with sustainability and conservation issues in the marine environment.
Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.
More than seventy percent of the earth's surface is covered by ocean - the home to a staggering and sometimes overwhelming diversity of organisms, a majority of which reside in pelagic form. Marine invertebrate larvae are an integral part of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This book will provide an important, modern update on the topic of larval ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content will be structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; climate change and larval ecology at the extremes. This novel synthesis will integrate traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research.
A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.
Human-wildlife conflict (HWC) has classically been defined as a situation where wildlife impacts humans negatively (physically, economically, or psychologically), and where humans likewise negatively impact wildlife. However, there is growing consensus that the conflict between people about wildlife is as important as the conflict between people and wildlife. HWC not only affects the conservation of one species in a particular geographic area, but also impacts the willingness of an individual, a community, and wider society to support conservation programs in general. This book explores the complexity inherent in these situations, covering the theory, principles, and practical applications of HWC work, making it accessible and usable for conservation practitioners, as well as of interest to researchers more concerned with a theoretical approach to the subject. Through a series of case studies, the book's authors and editors tackle a wide variety of subjects relating to conflict, from the challenges of wicked problems and common pool resources, to the roles that storytelling and religion can play in conflict. Throughout the book, the authors work with a Conservation Conflict Transformation (CCT) approach, adapted from the peacebuilding field to address the reality of conservation today. The authors utilise one of CCT's key analytic components, the Levels of Conflict model, as a tool to provide insight into their case studies. Although the examples discussed are from the world of marine conservation, the lessons they provide are applicable to a wide variety of global conservation issues, including those in the terrestrial realm. Human-Wildlife Conflict will be essential reading for graduate students and established researchers in the field of marine conservation biology. It will also be a valuable reference for a global audience of conservation practitioners, wildlife managers, and other conservation professionals.
Ecosystem-based fishery management (EBFM) is rapidly becoming the default approach in global fisheries management. The clarity of what EBFM means is sharpening each year and there is now a real need to evaluate progress and assess the effectiveness and impacts. By examining a suite of over 90 indicators (including socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria) for 9 major US fishery ecosystem jurisdictions, the authors systematically track the progress the country has made towards advancing EBFM and making it an operational reality. The assessment covers a wide range of data in both time (multiple decades) and space (from the tropics to the poles, representing over 10% of the world's ocean surface area). The authors view progress towards the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight the findings from a national perspective. Although US-centric, the lessons learned are directly applicable for all parts of the global ocean. Much work remains, but significant progress has already been made to better address many of the challenges facing the sustainable management of our living marine resources. This is an essential and accessible reference for all fisheries professionals who are currently practicing, or progressing towards, ecosystem-based fisheries management. It will also be of relevance and use to researchers, teachers, managers, and graduate students in marine ecology, fisheries biology, biological oceanography, global change biology, conservation biology, and marine resource management.
The tide is the greatest synchronised movement of matter on our planet. Every drop of seawater takes part in tidal motion, driven by the gravitational pull of the moon and sun. At the coast, we see the tide as a twice-daily rise and fall of sea level that moves the edge of the sea up and down a beach or cliff-face. In some places, the tide is small but at others it can rise in a few hours by the height of a three storey building; it then has to be treated with great respect by those who live and work by the sea. In this Very Short Introduction David George Bowers and Emyr Martyn Roberts explore what we know about the tides. Blending clear explanations of well known tidal phenomena with recent insights in the deep ocean and coastal seas, Bowers and Roberts use examples from around the world, to tell the story of the tide, considering its nature and causes, its observation and prediction, and unusual tides and their relevance. They explore why tides have attracted the attention of some of the world's greatest scientists, from the initial challenge of explaining why there are two tides a day when the moon and sun pass overhead just once; a problem that was solved by Isaac Newton. In the 19th century, scientists unravelled the rhythms of the tide; good tidal predictions in the form of tide tables were then possible. The predictions were made on beautiful tide predicting machines constructed of brass and mahogany, some of which can still be seen in maritime museums. In the 20th century, the importance of tides as mixers of sea water became evident. As Bowers and Roberts explore, tidal mixing of the ocean is essential for maintaining its deep circulation, a key part of the climate-control system of our planet. In inshore waters, tidal mixing enhances biological productivity, influences sea temperature and turbidity and creates dramatic features such as maelstroms and tidal bores. In the 21st century, space probes are examining the effects of tidal processes on the moons of Jupiter and Saturn and the possibility of tidally-heated liquid oceans with their own ecosystems. Looking to the cutting edge of tidal research, Bowers and Roberts also consider how we can study the role of the tide in the geological and biological evolution of our own planet with innovative computer models. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Whether through loss of habitat or cascading community effects, diseases can shape the very nature of the marine environment. Despite their significant impacts, studies of marine diseases have tended to lag behind their terrestrial equivalents, particularly with regards to their ecological effects. However, in recent decades global research focused on marine disease ecology has expanded at an accelerating rate. This is due in part to increases in disease emergence across many taxa, but can also be attributed to a broader realization that the parasites responsible for disease are themselves important members of marine communities. Understanding their ecological relationships with the environment and their hosts is critical to understanding, conserving, and managing natural and exploited populations, communities, and ecosystems. Courses on marine disease ecology are now starting to emerge and this first textbook in the field will be ideally placed to serve them. Marine Disease Ecology is suitable for graduate students and researchers in the fields of marine disease ecology, aquaculture, fisheries, veterinary science, evolution and conservation. It will also be of relevance and use to a broader interdisciplinary audience of government agencies, NGOs, and marine resource managers.
The biological composition and richness of most of the Earth's
major ecosystems are being dramatically and irreversibly
transformed by anthropogenic activity. Yet, despite the vast areal
extent of our oceans, the mainstay of research to-date in the
biodiversity-ecosystem functioning arena has been weighted towards
ecological observations and experimentation in terrestrial plant
and soil systems. This book provides a framework for examining the
mechanistic processes transferable to marine systems.

The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification," are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.
Global environmental change (including climate change, biodiversity
loss, changes in hydrological and biogeochemical cycles, and
intensive exploitation of natural resources) is having significant
impacts on the world's oceans. This handbook advances knowledge of
the structure and functioning of marine ecosystems, and their past,
present, and future responses to physical and anthropogenic
forcing. It illustrates how climate and humans impact marine
ecosystems, providing a comprehensive review of the physical and
ecological processes that structure marine ecosystems as well as
the observation, experimentation, and modelling approaches required
for their study. Recognizing the interactive roles played by humans
in using marine resources and in responding to global changes in
marine systems, the book includes chapters on the human dimensions
of marine ecosystem changes and on effective management approaches
in this era of rapid change. A final section reviews the state of
the art in predicting the responses of marine ecosystems to future
global change scenarios with the intention of informing both future
research agendas and marine management policy.

Caribbean coral reefs have unique species, are the world’s second largest coral reef community, and the most threatened. This book will be of major interest to all concerned with saving coral reefs from extinction. No other book available shows Caribbean coral reefs when they were at their best. It is only by comparing the images in this book with what they see now that people can recognize what we have lost. It is far more than they can imagine! Those who did not see it themselves can only do so through this book. Jim Porter’s insightful commentary in the Foreword adds crucial scientific perspective. Other books do not provide a one volume summary of all the major species on the Caribbean reef. This book is also more accurate in important systematic organization than other books in this field. The author’s excellent photographs convey clear concepts of processes and key aspects of species for identification. The book is written in an engaging story-telling style, yet clearly and concisely communicating the essential scientific concepts. Whereas most books have chapters dividing up one topic, this book is divided into different kinds of information which are essential to understanding coral reefs: how reefs are structured, corals, invertebrates, fishes, cryptic or hidden organisms, the community at night and others. One review states "After 52 years of researching coral reefs, I find this is the best book to present what reefs should be like, and were like 50 years ago. It is also written in a style accessible to recreational divers who wish to know the organisms, processes, and structures they are seeing." Another says "The first thing that will strikes the reader is the exquisite photography. There are many great underwater photographers, but the author is in a class by himself. Once the first impact of the astounding photography is accepted, the reader will be struck by what might be called the scientific integrity of the book." While this book is 'a time machine' taking the reader back to when these reefs thrived, there is optimism that we may see these reefs again as they appear in this book.

This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001). In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring programme; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed. Authored by a leading team this text is aimed at professionals in government and environment agencies, statisticians, biologists, wildlife managers, conservation biologists and ecologists, as well as graduate students, studying the density and abundance of biological populations.
Frigid, dark, and energy-deprived, the deep sea was long considered hostile to life. However, new sampling technologies and intense international research efforts in recent decades have revealed a remarkably rich fauna and an astonishing variety of novel habitats. These recent discoveries have changed the way we look at global biodiversity. In "Deep-Sea Biodiversity," Michael Rex and Ron Etter present the first synthesis of patterns and causes of biodiversity in organisms that dwell in the vast sediment ecosystem that blankets the ocean floor. They provide the most comprehensive analysis to date of geographic variation in benthic animal abundance and biomass. The authors document geographic patterns of deep-sea species diversity and integrate potential ecological causes across scales of time and space. They also review the most recent molecular population genetic evidence to describe how and where evolutionary processes have generated the unique deep-sea fauna. "Deep-Sea Biodiversity" offers a new understanding of marine biodiversity that will be of general interest to ecologists and is crucial to responsible exploitation of natural resources at the deep-sea floor.
Erratum: Table 11.1 on page 241 has been mis-set. The entries for the phyla Annelida, Bryozoa, Cnidaria, Echiura, Mollusca, Placozoa, Porifera and Rotifera should all be moved one column to the right. The deep sea environment is the most extensive on our planet. Its denizens are normally unseen but whenever they are exposed to view they are regarded as bizarre aliens from a different world. The Biology of the Deep Ocean takes a close look at this apparently hostile world and explains how its inhabitants are exquisitely adapted to survive and flourish within it. |
