Download or read book Human Impacts on Coral Reef Ecosystem written by Hussein El-Naggar and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthy, Coral reefs are the most spectacular, diverse and economically valuable marine ecosystems on the planet, Complex and productive, coral reefs are extremely important for biodiversity, providing a home to 35,000,Äì60,000 species of plants and animals (over 25% of all marine life), many of which are not described by science. They are also vital for people and business. They provide nurseries for many species of commercially important fish, protection of coastal areas from storm waves. They are providing hundreds of billions of dollars in food, jobs and significant attraction for the tourism industry. Yet coral reef ecosystems have undergone phase shifts to alternate, degraded assemblages because of the combined human activates of unsustainable overfishing, intensive tourism, urbanization, sedimentation, declining water quality, pollution and primarily from the direct and indirect impacts of climate change. Most coral ecologists confirm that coral reef degradation has increased dramatically during the last three decades due to enhanced anthropogenic disturbances and their interaction with natural stressors. So, it is necessary to recognize the threats facing coral reefs from anthropogenic activities and try to minimize and mitigate these impacts.

This book was released on 2019-04-05 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean acidification (OA). For the hundreds of millions of people who depend on reefs for food or livelihoods, the thousands of communities that depend on reefs for wave protection, the people whose cultural practices are tied to reef resources, and the many economies that depend on reefs for fisheries or tourism, the health and maintenance of this major global ecosystem is crucial. A growing body of research on coral physiology, ecology, molecular biology, and responses to stress has revealed potential tools to increase coral resilience. Some of this knowledge is poised to provide practical interventions in the short-term, whereas other discoveries are poised to facilitate research that may later open the doors to additional interventions. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs reviews the state of science on genetic, ecological, and environmental interventions meant to enhance the persistence and resilience of coral reefs. The complex nature of corals and their associated microbiome lends itself to a wide range of possible approaches. This first report provides a summary of currently available information on the range of interventions present in the scientific literature and provides a basis for the forthcoming final report.

Available in PDF, EPUB and Kindle. Book excerpt: This volume investigates the effects of human activities on coral reefs, which provide important life-supporting systems to surrounding natural and human communities. It examines the self-reinforcing ecological, economic and technological mechanisms that degrade coral reef ecosystems around the world. Topics include reefs and limestones in Earth history; the interactions between corals and their symbiotic algae; diseases of coral reef organisms; the complex triangle between reef fishes, seaweeds and corals; coral disturbance and recovery in a changing world. In addition, the authors take key recent advances in DNA studies into account which provides new insights into the population biology, patterns of species distributions, recent evolution and vulnerabilities to environmental stresses. These DNA analyses also provide new understandings of the limitations of coral responses and scales of management necessary to sustain coral reefs in their present states. Coral reefs have been essential sources of food, income and resources to humans for millennia. This book details the delicate balance that exists within these ecosystems at all scales, from geologic time to cellular interactions and explores how recent global and local changes influence this relationship. It will serve as an indispensable resource for all those interested in learning how human activities have affected this vital ecosystem around the world.

Download or read book The Great Barrier Reef written by Ben Daley and published by Routledge. This book was released on 2014-07-17 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Barrier Reef is located along the coast of Queensland in north-east Australia and is the world's largest coral reef ecosystem. Designated a World Heritage Area, it has been subject to increasing pressures from tourism, fishing, pollution and climate change, and is now protected as a marine park. This book provides an original account of the environmental history of the Great Barrier Reef, based on extensive archival and oral history research. It documents and explains the main human impacts on the Great Barrier Reef since European settlement in the region, focusing particularly on the century from 1860 to 1960 which has not previously been fully documented, yet which was a period of unprecedented exploitation of the ecosystem and its resources. The book describes the main changes in coral reefs, islands and marine wildlife that resulted from those impacts. In more recent decades, human impacts on the Great Barrier Reef have spread, accelerated and intensified, with implications for current management and conservation practices. There is now better scientific understanding of the threats faced by the ecosystem. Yet these modern challenges occur against a background of historical levels of exploitation that is little-known, and that has reduced the ecosystem's resilience. The author provides a compelling narrative of how one of the world's most iconic and vulnerable ecosystems has been exploited and degraded, but also how some early conservation practices emerged.
Download or read book Our Dying Planet written by Peter Sale and published by Univ of California Press. This book was released on 2011-09-12 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are on track to become the first ecosystem actually eliminated from the planet. So says leading ecologist Peter F. Sale in this crash course on the state of the planet. Sale draws from his own extensive work on coral reefs, and from recent research by other ecologists, to explore the many ways we are changing the earth and to explain why it matters. Weaving into the narrative his own firsthand field experiences around the world, Sale brings ecology alive while giving a solid understanding of the science at work behind today’s pressing environmental issues. He delves into topics including overfishing, deforestation, biodiversity loss, use of fossil fuels, population growth, and climate change while discussing the real consequences of our growing ecological footprint. Most important, this passionately written book emphasizes that a gloom-and-doom scenario is not inevitable, and as Sale explores alternative paths, he considers the ways in which science can help us realize a better future.

Download or read book Coral Reefs An Ecosystem in Transition written by Zvy Dubinsky and published by Springer Science & Business Media. This book was released on 2010-12-02 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers in one volume materials scattered in hundreds of research articles, in most cases focusing on specialized aspects of coral biology. In addition to the latest developments in coral evolution and physiology, it presents chapters devoted to novel frontiers in coral reef research. These include the molecular biology of corals and their symbiotic algae, remote sensing of reef systems, ecology of coral disease spread, effects of various scenarios of global climate change, ocean acidification effects of increasing CO2 levels on coral calcification, and damaged coral reef remediation. Beyond extensive coverage of the above aspects, key issues regarding the coral organism and the reef ecosystem such as calcification, reproduction, modeling, algae, reef invertebrates, competition and fish are re-evaluated in the light of new research and emerging insights. In all chapters novel theories as well as challenges to established paradigms are introduced, evaluated and discussed. This volume is indispensible for all those involved in coral reef management and conservation.
Download or read book Human Impacts on Caribbean Coral Reef Ecosystems written by Marah Justine Hardt and published by . This book was released on 2007 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing is one of the oldest anthropogenic disturbances in the ocean, differing from other impacts in its direct removal of biomass from the ecosystem. Despite the centuries of fishing activities, there is much we still do not understand regarding the effects of fish removal on the benthic community. I use an interdisciplinary approach to investigate the affect of human disturbance, primarily the alteration of fish communities, on major functional groups of coral reefs, over extended temporal and spatial scales. In Chapter 2 , historical analyses reveal that relatively small human populations and simple fishing technologies can negatively impact reef fish communities. Significant declines are evident in Pre Columbian times and by the mid 19 th C. Declines were exacerbated by simple innovations of gear, such as chicken wire, and government subsidies, which expanded degradation to offshore and deeper reefs. In Chapter 3, I identify six major ecological guilds of common Caribbean coral species and show that changes in the abundance of these guilds from the Pleistocene to the present day can be understood in terms of recent human disturbance events. Formerly advantageous life history strategies no longer apply. Instead, guilds with the ability to withstand physical disturbance from storms, sedimentation, and pollution remain present on reefs, while strategies for high recruitment and rapid space colonization increase the relative abundance of another guild. Overall, no guild successfully competes with macroalgae for space and all corals have declined. In Chapter 4, I show that benthic and fish communities across the northwestern Caribbean are largely homogenized as a result of human disturbance. The exception is fish communities in large, no-take marine reserves, which resemble relatively healthy communities of low-impacted reefs in the Pacific. A negative correlation between fish and algal biomass indicate that reserves may facilitate coral recovery, although corals have not yet increased. Chapter 5 describes a novel method for calculating the wet and dry animal tissue mass per unit area of corals. Chapter 6 integrates these findings and demonstrates the importance of increased temporal, spatial, and ecosystem scale in effective research and management of degraded Caribbean coral reefs.
Download or read book Coral Reefs written by Thomas B. Davin and published by Nova Science Pub Incorporated. This book was released on 2009 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are ancient and extremely complex communities functioning as a single unit. They are the 'rain forests of the sea,' containing the richest biodiversity of all marine ecosystems. This book examines the biological aspects of coral reefs and the importance of their existence. Environmental threats to coral reefs are reviewed (i.e., global warming, overfishing), and ways in which the coral reef ecosystem can be restored are also discussed. Marine ornamental fish play an extremely important role today in the international fish trade. The data on breeding and rearing protocols for some of these high value marine ornamental species are reviewed. Phototrophic dinoflagellates called zooxanthellae and their possible role in coral reef management are also described. Furthermore, the causes of reef damage such as destructive fishing methods are examined. Other examples of adverse human impacts on coral reef sustainability, such as over-fishing, are also reviewed. It is suggested that coral calcification is closely coupled with carbon dioxide in seawater. This book describes the impact of anthropogenic surface ocean acidification with increasing atmospheric carbon dioxide on coral calcification. In addition, changes of caspases in the brains of hypoxic fish are examined by comparing a coral reef with a freshwater teleost. This book also provides a basic knowledge of tsunami effects on coral reefs to aid in the future evaluations of coral damage by tsunamis.
