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.

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 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.

Tropical coral reefs are important ecosystems. They are economically important to coastal communities living in predominantly developing countries, and also provide shoreline protection, catalyse land formation enabling human habitation, act as a carbon sink and are a repository for genetic and species diversity rivalling rainforests. In the face of mounting man-made pressure from pollution, climate change and over-exploitation, these ecosystems increasingly need action to be taken to ensure their conservation and long term sustainable development. International Environmental Law and the Conservation of Coral Reefs breaks new ground by providing the first in-depth account of the ways in which multilateral environmental treaty regimes are seeking to encourage and improve the conservation of tropical coral reef ecosystems. In so doing, the work aims to raise the profile of such activities in order to reinforce their status on the environmental agenda. The book also has wider implications for international environmental law, arguing that sectorial legal action, provided it remains co-ordinated through a global forum that recognises and reflects the inter-connections between all elements of the natural environment, is the most effective way for international law to enhance the conservation of certain habitats. This book will be invaluable to environmental lawyers, legal researchers, marine conservationists and other stakeholders in coral reefs.

Australia's coral reefs stretch far and wide, covering 50 000 square kilometres from the Indian Ocean in the West to the Pacific Ocean in the East. They have been viewed as a bedrock of coastal livelihoods, as uncharted and perilous nautical hazards, as valuable natural resources, and as unique, natural wonders with secrets waiting to be unlocked. Australia's coral reefs have sustained a global interest as places to visit, and as objects of study, science, protection and conservation."Coral Reefs of Australia" examines our evolving relationship with coral reefs, and explores their mystery and the fast pace at which they are now changing. Corals are feeling the dramatic impacts of global climate change, having undergone several devastating mass coral bleaching events, dramatic species range shifts and gradual ocean acidification. This comprehensive and engaging book brings together the diverse views of Indigenous Australians, coral reef scientists, managers and politicians to reveal how we interact with coral reefs, focussing on Indigenous culture, coastal livelihoods, exploration, discovery, scientific research and climate change. It will inform and inspire readers to learn more about these intriguing natural phenomena and how we can protect coral reefs for the future.

Coral reefs are critical to ocean and human life because they provide food, living area, storm protection, tourism income, and more. However, human-induced stressors, such as overfishing, sediment, pollution, and habitat destruction have threatened ocean ecosystems globally for decades. In the face of climate change, these ecosystems now face an array of unfamiliar challenges due to destructive rises in ocean temperature, acidity and sea level. These factors lead to an increased frequency of bleaching events, hindered growth, and a decreasing rate of calcification. Research on interventions to combat these relatively new stressors and a reevaluation of longstanding interventions is necessary to understand and protect coral reefs in this changing climate. Previous research on these methods prompts further questions regarding the decision making process for site-specific interventions. A Decision Framework for Interventions to Increase the Persistence and Resilience of Coral Reefs builds upon a previous report that reviews the state of research on methods that have been used, tested, or proposed to increase the resilience of coral reefs. This new report aims to help coral managers evaluate the specific needs of their site and navigate the 23 different interventions described in the previous report. A case study of the Caribbean, a region with low coral population plagued by disease, serves as an example for coral intervention decision making. This report provides complex coral management decision making tools, identifies gaps in coral biology and conservation research, and provides examples to help individuals and communities tailor a decision strategy to a local area.

Managing Coral Reefs examines Indonesia’s and Malaysia’s pathways to implementing the Convention on Biological Diversity (CBD), focusing specifically on how regional and national policies in Southeast Asia have fared when implementing the Aichi Targets of the CBD. Kelly Heber Dunning examines CBD implementation through marine protected areas (MPAs) for coral reefs in Indonesia and Malaysia. While Indonesia uses a co-managed framework, whereby villages and governments share power, to implement its MPAs, Malaysia uses a top-down network of federally managed marine parks. Using mixed methods through interviews and surveys as well as coral reef ecology surveys conducted over a year of fieldwork, Dunning argues that co-managed systems are the current best practice for implementing the CBD’s Aichi Targets in tropical developing countries.
