Download or read book Large Marine Ecosystems of the World written by Gotthilf Hempel and published by Elsevier Science. This book was released on 2003 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Large Marine Ecosystems (LMEs) of the world annually produce 95% of usable global marine biomass. LMEs are presently being subjected to stresses from unsustainable fishing, climate change, coastal eutrophication, toxic algal blooms and degradation of critical habitats, resulting in significant losses of socioeconomic benefits to coastal countries. The volume provides assessments of the changing states of selected polar, temperate and tropical LMEs using the case study method. From the studies of changes in biomass yields and environmental health, new insights are provided on the causes of the changes and actions presently underway to improve the health and sustainability of LMEs. Twelfth in the series on LMEs (see http://www.lme.noaa.gov), this book is essential reading for scientists and students in marine relevant fields, conservationists, marine resource managers, policy makers and others interested in the fate of ocean ecosystems.

Download or read book Jellyfish Blooms IV written by Jennifer Purcell and published by Springer. This book was released on 2015-03-21 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jellyfish generally are considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen, killing fish in aquaculture pens, and being both predators and competitors of fish. There is concern that environmental changes such as global warming, eutrophication, over-fishing, and coastal construction may benefit jellyfish populations. During this past decade following the first Jellyfish Blooms volume, some species have bloomed more frequently, expanded their range, and caused more problems for humans. Mnemiopsis leidyi, the ctenophore that invaded the Black Sea in the 1980s and damaged fisheries, now also blooms in the North, Baltic, and Mediterranean seas. Nemopilema nomurai, a giant Asian jellyfish, has bloomed frequently during this decade, causing severe damage to the Japanese fishing industry. Jellyfish Blooms: Interactions with Humans and Fisheries is the fourth volume in this series. Syntheses and original research articles address the question if jellyfish have increased globally and what factors may have contributed to the abundance of jellyfish. This volume is the most extensive to date, containing papers from all continents (except Antarctica) on scyphozoans, hydrozoans, cubozoans, staurozoans, and ctenophores, and on the fate of jellyfish blooms. This is a key reference for students and professional marine biologists, oceanographers, and fishery scientists and managers. Previously published in Hydrobiologia, vol. 690, 2012

These relatively narrow ocean zones, which produce nearly 95% of useable marine biomass, are becoming increasingly stressed both by natural and anthropogenic changes. The potential for consequent negative effects on global ecologies and economies has aroused major international concern. This new volume is a state-of-the-art update on large marine ecosystems, representing a multidisciplinary effort to develop a more holistic approach to the research, monitoring and mangaement of marine resources.
Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Download or read book Marine Protected Areas written by National Research Council and published by National Academies Press. This book was released on 2001-06-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.
Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
Download or read book In a Perfect Ocean written by Daniel Pauly and published by Washington : Island Press. This book was released on 2003 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
Download or read book Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.
Download or read book Large Marine Ecosystems of the North Atlantic written by K. Sherman and published by Elsevier. This book was released on 2002-04-16 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to provide assessments of multidecadal changes in resources and environments of the Large Marine Ecosystems (LMEs) of the North Atlantic. Using the case study method, researchers examine the forces driving the changes and actions underway aimed at turning the corner from declining trends in biomass yields, toward recovery of depleted species populations and improvements in ecosystem integrity. Recently a distinguished group of 24 scientists argued eloquently that a new Sustainability Science was emerging that was focused on "meeting fundamental human needs while preserving the life support systems of planet Earth". The contributions contained in this volume are at the cutting edge of Sustainability Science and the results presented by the contributors are pertinent to one of the core questions: "How are long-term trends in environment and development, including consumption and population, reshaping nature-society interactions in ways relevant to sustainability?" (Science Vol. 292, 27 April 2001). The case studies demonstrate the utility of an ecosystem-based approach to the assessment and management of biomass yields and species sustainability. Movements toward ecosystem-based management have emerged from the case studies on the initiation of recoveries of several depleted groundfish stocks of the US Northeast Shelf LME; the collapse of the Newfoundland-Labrador Shelf cod; the assessment of physical and biological changes on the Scotian Shelf, West Greenland Shelf, Iceland Shelf LME, and the Faroe Plateau, the North Sea, and the Barents Sea LMEs. Uncertainties, with regard to environmental and human-generated forcing, are addressed in assessment of the states of the Iberian Coastal and Biscay-Celtic LMEs, and in broad-scale studies of the influences at the base of the food chain of climatic variability on the productivity and biodiversity of plankton communities of the North Atlantic. The volume concludes with an insightful perspective on the approaches used and the results reported by the eminent marine scientist and former President of ICES, Professor Gotthilf Hempel.

This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.
Download or read book Marine Coastal Ecosystems Modelling and Conservation written by Marco Ortiz and published by Springer Nature. This book was released on 2020-12-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Niño, and La Niña. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins ́ Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.

Download or read book Conserving the Oceans written by Justin Alger and published by Oxford University Press. This book was released on 2021 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Conserving the Oceans: The Politics of Large Marine Protected Areas documents the efforts of activists and states to increase the pace and scale of global ocean protections, leading to a new global norm in ocean conservation of large marine protected areas exceeding 200,000 km2. Through an analysis of domestic political economies, the book explains how states have protected millions of square kilometers of ocean space while remaining highly responsive to the interests of businesses. It argues that states design environmental policies above all around two key features of a given space: (1) the composition of extractive versus non-extractive industry interests; and (2) the salience of various industry interests, defined as the degree to which businesses would suffer tangible and significant costs in response to new environmental regulations. Through an analysis of large marine protected area advocacy campaigns in Australia, Palau, and the United States, this book demonstrates how the political economy of a given marine space shapes how governments align their environmental and economic goals, sometimes strengthening conservation but more often than not undermining it. While recognizing important global progress and growing ambition to conserve ocean ecosystems, Conserving the Oceans demonstrates that even ambitious large marine protected areas have so far not fundamentally challenged a neoliberal paradigm of environmentalism that has caused considerable ecological harm"--
Download or read book Large Marine Ecosystems of the Indian Ocean written by Kenneth Sherman and published by John Wiley & Sons. This book was released on 2009-06-01 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume marine experts from countries of East Africa and southern Asia describe the conditions of marine resources of the large marine ecosystems of the Indian Ocean. Countries of the region represent over a quarter of the world's population, most of whom are existing at or below the poverty level. The potentials for economic growth through the development of coastal tourism, mariculture, fisheries, mineral extraction, and oil and gas production are examined by the authors in relation to the need for ensuring the long-term sustainability of marine resources. Case studies of resource assessments presented by several authors illustrate the magnitude of risk from continuing degradation of resources under the prevailing unmanaged conditions extending over much of coastal areas of East Africa and southern Asia. The authors explore the application of multidisciplinary ecosystem-based assessment and management strategies to the future economic development of the large marine ecosystems of the region. With the initiation of science-based management practcies, the ecosystems of the area can provide an important source of economic growth, improved food security, and nutritional benefits to the populations of stakeholders in coastal areas bordering the Indian Ocean
