Download or read book The Biology of Coral Reefs written by Charles R. C. Sheppard and published by Oxford University Press. This book was released on 2018 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs represent the most spectacular and diverse marine ecosystem on the planet as well as a critical source of income for millions of people. However, the combined effects of human activity have led to a rapid decline in the health of reefs worldwide, with many now facing complete destruction. Their world-wide deterioration and over-exploitation has continued and even accelerated in many areas since the publication of the first edition in 2009. At the same time, there has been a near doubling in the number of scientific papers that have been written in this short time about coral reef biology and the ability to acclimate to ocean warming and acidification. This new edition has been thoroughly revised and updated, incorporating the significant increase in knowledge gained over the last decade whilst retaining the book's focus as a concise and affordable overview of the field. The Biology of Coral Reefs provides an integrated overview of the function, physiology, ecology, and behaviour of coral reef organisms. Each chapter is enriched with a selection of 'boxes' on specific aspects written by internationally recognised experts. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate this marine environment although pollution, conservation, climate change, and experimental aspects are also included. Indeed, particular emphasis is placed on conservation and management due to the habitat's critically endangered status. A global range of examples is employed which gives the book international relevance.

Available in PDF, EPUB and Kindle. Book excerpt: Coral disease is quickly becoming a crisis to the health and management of the world’s coral reefs. There is a great interest from many in preserving coral reefs. Unfortunately, the field of epizootiology is disorganized and lacks a standard vocabulary, methods, and diagnostic techniques, and tropical marine scientists are poorly trained in wildlife pathology, veterinary medicine, and epidemiology. Diseases of Coral will help to rectify this situation.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

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.
Download or read book Developing Recent Mortality as an Ecosystem Indicator to Enhance Coral Monitoring written by Nathan Formel and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study developed percent recent mortality to be used as a community-wide indicator of coral reef stress response. Ecosystem indicators are tools used to simplify the monitoring of processes on coral reefs, such as stress response, as well as simplify the communication of these results to the public. Percent recent mortality is a metric used in some of southeast Florida's long-term reef monitoring projects and shows great promise as an ecological indicator of coral stress response and, inversely, coral health. To develop percent recent mortality for use as an ecological indicator on south Florida reefs, the metric was evaluated using a set of 11 criteria designed by the Marine and Estuarine Goal Setting for South Florida (MARES) project. Having fulfilled the criteria, survey data from the past 10 years were used to determine minimally impaired reference baselines and stress response benchmarks. Percent recent mortality was designed as a stoplight indicator to improve both utility and communication of the indicator. As an ecological indicator, percent recent mortality has the advantage of simplicity as a measurement of stress experienced in a complex ecosystem. There is more work that can be done to develop this indicator for a wider usage at finer and more accurate scales as an indicator of coral stress response. As percent recent mortality is further utilized as an ecological indicator the data collected will assist its continued improvement and refinement.

Download or read book Marine Organisms as Indicators written by Dorothy F. Soule and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for a volume dealing with the concept of indicator organisms became evident during a symposium on the subject, organized by the present editors for the Southern California Academy of Sciences. Ques tions were posed about the appropriate uses of indicator organisms and the "rules" governing the application of the indicator concept to particular problems. For example, how does one distinguish true indicators from biological anomalies? What kinds of organisms can appropriately be associated with conditions and events at various scales in time and space? To what extent does one species represent other species in the same environmental setting? Can the indicator concept be applied to the context of modern sampling and analytical technology? How can anthropogenic perturbations be distinguished from natural phenomena? How can unlike matrices from differing data bases with differing scales best be matched? Such questions are especially pertinent in today's research environment. The use of indicator organisms, while certainly not new, is the corner stone for much scientific research. In the past two decades, indicator organisms have played increasingly important roles in the development and implementation of public policy. In particular, indicator organisms are being used to describe local environments and natural or anthropogenic perturbations to them, although there are pitfalls and problems associated with those usages. A growing number of nonbiologists, including physical oceanographers, find indicator organisms helpful, and sometimes essential, to their re search.
Download or read book Assessing the Health of Coral Reef Ecosystems in the Florida Keys at Community Individual and Cellular Scales written by Elizabeth M. Fisher and published by . This book was released on 2007 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are threatened in Florida and worldwide. Successful resource management requires rapid identification of anthropogenic sources of stress before they affect the reef community. I tested a multi-scale approach for assessing reef condition at seven reefs within the Florida Keys National Marine Sanctuary and Biscayne National Park between 2001 and 2003. I examined multiple environmental parameters to identify potential sources of stress. I utilized the Atlantic and Gulf Rapid Reef Assessment Biotic Reef Index to assess benthic community structure and an indicator species of Foraminifera (Amphistegina gibbosa) to determine if environmental conditions were suitable for calcareous organisms that host algal endosymbionts. Small tissue samples were extracted from colonies of Montastraea annularis species complex to assay a suite of cellular biomarkers to elucidate possible mechanisms of the coral stress response. I monitored regeneration rates of the resultant lesions to determine if the coral colonies were capable of recovering from damage. Multivariate data analyses indicated that corals at all study sites were experiencing stress with different degrees of response and decline. On reefs with coarse grain sediments that are adjacent to an intact mangrove shoreline, the Cellular Diagnostic System indicated that corals were responding to a xenobiotic stress but appeared to be compensating as evidenced by consistently high lesion regeneration rates, a high percentage of healed lesions, low coral mortality and high abundances of A. gibbosa. On reefs with silt-sized sediments adjacent to developed coastlines, corals also were responding to xenobiotic stresses, but were negatively affected as evidenced by low regeneration rates, a low percentage of healed lesions, high coral mortality, and low abundances of A. gibbosa. Corals at an 18 m offshore site exhibited abnormally low biomarker levels and some died during the study, indicating that sampled colonies were incapable of upregulating necessary protective proteins. Further research will be required to determine stressor sources. This study demonstrates that a multiple-indicator approach, spanning scales from cellular to community, can provide marine resource managers with data linking decline of coral populations to specific environmental conditions and events, thereby providing potential for early detection of stressors allowing for preventive management.

Book excerpt: Are coral reefs sufficiently resilient to withstand the changing environmental conditions of the future? Research is necessary to gain a better understanding of how reefs will respond and how resilient they are. Various approaches to characterize and analyze reef responses from the molecular to community and habitat levels are all essential. Trends could be analyzed from spatially extensive and/or long-term monitoring data and applied to novel management strategies. Reef resilience research continues to remain relevant and important to the future of coral reefs. The contributions in this volume provide a further dimension to the understanding of reef resilience.
