The deep ocean is by far the planet's largest biome and holds a wealth of potential natural assets. Human exploitation of the deep ocean is rapidly increasing whilst becoming more visible to many through the popular media, particularly film and television. The scientific literature of deep-sea exploitation and its effects has also rapidly expanded as a direct function of this increased national and global interest in exploitation of deep-sea resources, both biological (e.g. fisheries, genetic resources) and non-biological (e.g. minerals, oil, gas, methane hydrate). At the same time there is a growing interest in deep-sea contamination (including plastics), with many such studies featured in high profile scientific journals and covered by global media outlets. However, there is currently no comprehensive integration of this information in any form and these topics are only superficially covered in classic textbooks on deep-sea biology. This concise and accessible work provides an understanding of the relationships between biodiversity and ecosystem functioning, both at the seafloor and in the water column, and how these might be affected as a result of human interaction, exploitation and, ultimately, environmental change. It follows a logical progression from geological and physical processes, ecology, biology, and biogeography, to exploitation, management, and conservation. Natural Capital and Exploitation of the Deep Ocean is aimed at marine biologists and ecologists, oceanographers, fisheries scientists and managers, fish biologists, environmental scientists, and conservation biologists. It will also be of relevance and use to a multi-disciplinary audience of fish and wildlife agencies, NGOs, and government departments involved in deep-sea conservation and management.

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives.

This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN.

As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms.

The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

These two volumes offer a treasure house of information to the students and researchers of plant sciences, biological sciences, agricultural sciences, foods and nutrition sciences, health sciences and environmental sciences. Their practical value will benefit professionals including agriculture and food experts, biotechnologists, ecologists, environmentalists, and biomass specialists. This set will also aid industries dealing with foods, nutraceuticals, pharmaceuticals , cosmecuticals health care products, and bioenergy.

Death at SeaWorld centres on the battle with the multimillion-dollar marine park industry over the controversial and even lethal ramifications of keeping killer whales in captivity. Following the story of Naomi Rose, a marine biologist and animal advocate at the Humane Society of the U.S., Kirby tells the gripping story of the two-decade fight against PR-savvy SeaWorld, which came to a head with the tragic death of trainer Dawn Brancheau in 2010. Kirby puts that horrific animal-on-human attack in context. Brancheau's death was the most publicised among several brutal attacks that have occurred at Sea World and other marine mammal theme parks.

Marine environmental history analyses the changing relationships between human societies and marine natural resources over time. This is the first book which deals in a systematic way with the theoretical backgrounds of this discipline. Major theories and methods are introduced by leading scholars of the field. The book seeks to encapsulate some of the major novelties of this fascinating new discipline and its contribution to the management, conservation and restoration of marine and coastal ecosystems as well as the cultural heritages of coastal communities in different parts of the world.

This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos - dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes. The papers herein represent wide-ranging topics, from the processes that structure microbial diversity to nitrogen and photosynthesis metabolism, to dynamics of changing ecosystems and processes and dynamics in individual ecosystems. In all, these papers take us from the Arctic to Africa, from the Arabian Sea to Australia, from small lakes in Maine and Yellowstone hot vents to the Sargasso Sea, and in the process provide analyses that make us think about the structure and function of all of these systems in the aquatic realm. This book is useful not only for the depth and breadth of knowledge conveyed in its chapters, but serves to guide dual career couples faced with the great challenges only they face. Great teams do make great science.

This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

This volume summarizes recent advances in environmental microbiology by providing fascinating insights into the diversity of microbial life that exists on our planet. The first two chapters present theoretical perspectives that help to consolidate our understanding of evolution as an adaptive process by which the niche and habitat of each species develop in a manner that interconnects individual components of an ecosystem. This results in communities that function by simultaneously coordinating their metabolic and physiologic actions. The third contribution addresses the fossil record of microorganisms, and the subsequent chapters then introduce the microbial life that currently exists in various terrestrial and aquatic ecosystems. Coverage of the geosphere addresses endolithic organisms, life in caves and the deep continental biosphere, including how subsurface microbial life may impact spent nuclear fuel repositories. The discussion of the hydrosphere includes hypersaline environments and arctic food chains. By better understanding examples from the micro biosphere, we can elucidate the many ways in which the niches of different species, both large and small, interconnect within the overlapping habitats of this world, which is governed by its microorganisms.

This book provides an overview of floating offshore wind farms and focuses on the economic aspects of this renewable-energy technology. It presents economic maps demonstrating the main costs, and explores various important aspects of floating offshore wind farms. It examines topics including offshore wind turbines, floating offshore wind platforms, mooring and anchoring, as well as offshore electrical systems. It is a particularly useful resource in light of the fact that most water masses are deep and therefore not suitable for fixed offshore wind farms. A valuable reference work for students and researchers interested in naval and ocean engineering and economics, this book provides a new perspective on floating offshore wind farms, and makes a useful contribution to the existing literature.

"Freshwater Algae of North America, Second Edition" is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. Scientists from many disciplines, from evolutionary biology to DNA bar-coding to ecosystem management, rely on up-to-date information on the biology and classification of algae. This book brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments), providing all of this comprehensive information in a single volume.

In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms.
Extensive and complete, this book describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus.Full-color images throughout provide superb visual examples of freshwater algae, as photosynthetic pigments play a critical role in their identificationUpdated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB)Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problemsUpdated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies

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.

The book presents recent research on marine ecology in different parts of the world. It aims to shed light on relevant topics for budding marine ecologists. The "blue soup" of Planet Earth, which comprises both biotic and abiotic components, is essential to keeping the wheel of civilization running. Four major ecosystem service categories have been identified within this context, namely provisioning services such as water, food, mangrove timber, honey, fish, wax, fuel wood, fodder and bioactive compounds from marine and estuarine flora and fauna; regulating services such as the regulation of climate, coastal erosion, coral bleaching and pollution; cultural services encompassing recreational (tourism), spiritual and other non-material benefits; and supporting services such as nutrient cycling and photosynthesis. These valuable services are obtained from various resources that must be conserved for the sake of humanity. This book presents data for each resource type, not just in the form of a simple description, but also through case studies that resulted from several research projects and pilot programs carried out in different parts of the world. Statistical tools were also used to critically analyze the influence of relevant hydrological parameters on the biotic community. Advanced research in marine and estuarine ecology is based on the use of sophisticated instruments, sampling precision, statistical tools, etc., which have also been highlighted in the book.

This book explores the ethnobiology of corals by examining the various ways in which humans, past and present, have exploited and taken care of coral and coralline habitats. This book will bring the educated general audience closer to corals by exploring the various circumstances of human-coral coexistence by providing scientifically sound and jargon-free perspectives and experiences from across the globe. Corals are a vital part of the marine environment since they promote and sustain marine and global biodiversity while providing numerous other environmental and cultural services. Countless valuable coral conservation efforts are published in academic and general audience venues on a daily basis. However relevant, few of these reports show a direct, deeper understanding of the intimate relationship between people and corals throughout the world's societies. Ethnobiology of Corals and Coral Reefs establishes an intimate bond between the audience and the wonder of corals and their importance to humankind.

The book provides an overview of research on the remarkable diversity, adaptive genetic differentiation, and evolutionary complexity of intertidal macroalgae species. Through incorporating molecular data, ecological niche and model-based phylogeographic inference, this book presents the latest findings and hypotheses on the spatial distribution and evolution of seaweeds in the context of historical climate change (e.g. the Quaternary ice ages), contemporary global warming, and increased anthropogenic influences. The chapters in this book highlight past and current research on seaweed phylogeography and predict the future trends and directions. This book frames a number of research cases to review how biogeographic processes and interactive eco-genetic dynamics shaped the demographic histories of seaweeds, which furthermore enhances our understanding of speciation and diversification in the sea. Dr. Zi-Min Hu is an associate professor at Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China.

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.

This book focuses on the interaction between shipping and the natural environment and how shipping can strive to become more sustainable. Readers are guided in marine environmental awareness, environmental regulations and abatement technologies to assist in decisions on strategy, policy and investments. You will get familiar with possible paths to improve environmental performance and, in the long term, to a sustainable shipping sector, based on an understanding of the sources and mechanisms of common impacts. You will also gain knowledge on emissions and discharges from ships, prevention measures, environmental regulations, and methods and tools for environmental assessment. In addition, the book includes a chapter on the background to regulating pollution from ships. It is intended as a source of information for professionals connected to maritime activities as well as policy makers and interested public. It is also intended as a textbook in higher education academic programmes.

When people hear the word “migration,” they think of animals that move from a feeding area to a breeding area and back each year. But the greatest migration on Earth happens twice every night. The movement is largely vertical and performed by plankton followed by predatory fish, squid, octopus and other species that have acquired a taste for plankton. The migration starts deep in the waters of the ocean at sunset. As they move, the plankton nibble on plant plankton and other tasty morsels in the water and, eventually, some on each other. The feeding ends just before dawn when the plankton retreat to the depths of the ocean to hide during the day until the next evening, when they migrate back up the water column. In Planktonia, Erich Hoyt invites readers to dive into the dazzling nighttime ocean. Countless microscopic plankton — larval creatures such as ornate ghost pipefish, left-handed hermit crabs and bony-eared assfish — ascend to the upper waters to feed, returning to the depths before sunrise. These tiny planktonic creatures are delicate and beautiful; some look terrifying; and most look nothing like the creatures they will become as adults. This great vertical migration attracts larger adult creatures, too, from the solitary 6-inch (15 cm) bigfin reef squid and the fierce and hungry 6½ foot (2 m) female blanket octopus, which is up to 40,000 times heavier than her male mate. Everyone comes here for the midnight feast, and they are all ravenously hungry. Chapters in this book include: Hawai’i: From Bluewater to Blackwater; Awesome Anilao; The Gulf Stream Procession of Life; Blackwater White Sea; Precious Life of Plankton; Blackwater Unlimited; From Blackwater Passion to Protection. All life in the ocean depends on plankton. Plankton plays a key role in sequestering carbon against climate change. The great nightly vertical migration highlights the importance of protecting not only ocean species but also ecosystems that embrace ocean processes from the depths of the sea to surface waters.

This is the second edition of Freshwater Algae; the popular guide to temperate freshwater algae. This book uniquely combines practical information on sampling and experimental techniques with an explanation of basic algal taxonomy plus a key to identify the more frequently-occurring organisms. Fully revised, it describes major bioindicator species in relation to key environmental parameters and their implications for aquatic management. This second edition includes: the same clear writing style as the first edition to provide an easily accessible source of information on algae within standing and flowing waters, and the problems they may cause the identification of 250 algae using a key based on readily observable morphological features that can be readily observed under a conventional light microscope up-to-date information on the molecular determination of taxonomic status, analytical microtechniques and the potential role of computer analysis in algal biology upgrades to numerous line drawings to include more detail and extra species information, full colour photographs of live algae including many new images from the USA and China Bridging the gap between simple identification texts and highly specialised research volumes, this book is used both as a comprehensive introduction to the subject and as a laboratory manual. The new edition will be invaluable to aquatic biologists for algal identification, and for all practitioners and researchers working within aquatic microbiology in industry and academia.

Orcas are the most profitable and controversial display animal in history, and since the release of the documentary Blackfish in 2013, millions around the world have focused on their plight. Yet no historical account has explored how we came to care about killer whales in the first place. In Orca, Jason Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s-the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when a Seattle entrepreneur named Ted Griffin became the first person to swim and perform with a captive killer whale. The show was a hit, and he began capturing and selling others, including Sea World's first "Shamu." Over the following decade, live display transformed popular and scientific views of Orcinus orca. The public embraced killer whales as charismatic and friendly while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity. So when Sea World attempted to catch its own killer whales, Northwesterners would fight for the freedom of a marine predator that had become a regional icon. With access to previously unavailable documents and interviews, Colby offers the definitive history of how the feared and despised "killer" became the beloved "orca" and what that means for our relationship with the ocean and its creatures.

This book began life as a series of lectures given to second and third year undergraduates at Oxford University. These lectures were designed to give students insights as to how marine ecosystems functioned, how they were being affected by natural and human interventions, and how we might be able to conserve them and manage them sustainably for the good of people, both recreationally and economically. This book presents 10 chapters, beginning with principles of oceanography important to ecology, through discussions of the magnitude of marine biodiversity and the factors influencing it, the functioning of marine ecosystems at within trophic levels such as primary production, competition and dispersal, to different trophic level interactions such as herbivory, predation and parasitism. The final three chapters look at the more applied aspects of marine ecology, discussion fisheries, human impacts, and management and conservation.

Other textbooks covering similar topics tend to treat the topics from the point of view of separate ecosystems, with chapters on reefs, rocks and deep sea. This book however is topic driven as described above, and each chapter makes full use of examples from all appropriate marine ecosystems. The book is illustrated throughout with many full colour diagrams and high quality photographs.

The book is aimed at undergraduate and graduate students at colleges and universities, and it is hoped that the many examples from all over the world will provide global relevance and interest.

Arctic marine ecosystems are largely impacted by changes associated with global warming. The sea ice in Greenland Sea plays an important role in regional and global climate system. The book investigate the relationships between phytoplankton biomass, measured using remotely sensed chlorophyll-a (CHL), aerosol optical depth (AOD) and sea-ice cover (ICE) in the Greenland Sea (20 DegreesW-10 DegreesE, 65-85 DegreesN) over the period 2003-2012. First hand Satellite data was used to do correlation analysis. Enhanced statistics methods, such as lag regression method and cointegration analysis method are used for correlation and regression analysis between 2 variables (up to 3 variables). ARMA model was used to prediction time series in the future 3 years. The book not only gives outline of ecosystem in Greenland Sea, how the ice impact to the local ecosystems, but also provides valuable statistical methods on analysis correlations and predicting the future ecosystems.
