Coral reef communities are among the most complex, mature and productive ecosystems on earth. Their activity resulted in the creation of vast lime constructions. Being extremely productive and having the function of a powerful biofilter, coral reefs play an important role in global biogeochemical processes and in the reproduction of food resources in tropical marine regions. All aspects of coral reef science are covered systematically and on the basis of a holistic ecosystem approach. The geological history of coral reefs, their geomorphology as well as biology including community structure of reef biota, their functional characteristics, physiological aspects, biogeochemical metabolism, energy balance, environmental problems and management of resources are treated in detail.

The health status and future of tropical coral reefs, as tourist destinations, are regularly subjected to media coverage. Many documentaries recognize the natural beauty and biological richness of the Australian Great Barrier Reef and French Polynesian lagoons, but point to the equally significant risk that would result from current global warming and human-made hazards. The future of coral reefs is usually a matter of death foretold, real or purely imaginary. In this context, it has become necessary to differentiate between what is falling within reality of scientific facts or fantasy. To this end, the present general review, in the expert translation of Charlotte Fontan aims at: (1) defining the conditions and life requirements of reefbuilding corals; (2) the history of corals along with that of a number of associated, skeletal organisms involved in reef building since the very beginning, i.e. the last 540 million years, including the ups and downs they have experienced; (3) giving special reference to the development patterns of recent and modern reefs; (4) projecting corals and reefs into a still unknown future. Understanding how corals and reefs have originated, how they have been able to face the major biological crises which have punctuated the Earth’s history, how they have survived is a prerequisite to better gain a significant picture of their future.

Coral reefs represent one of the most productive ecosystems in the world, fostering immense biomass and biodiversity. Local disturbances, global climate change and poor recruitment are causing coral reefs to decline at prodigious rates. Variability in response to these stressors at a local level makes management and reconstruction of coral reefs challenging. For example, reef managers lack the ability to accurately predict the relative stress and the reef-specific response to the increased heating caused by global climate change as this can be dictated by the endosymbiont variability, bleaching history, flow dynamics and microbial community composition. Similarly, reef reconstruction efforts remain ineffective as worsening environmental conditions are driving lower levels both recruitment of coral larvae and survival of the new recruits. These environmental fluctuations are accompanied by large changes in the composition and concentration of the dissolved organic matter (DOM) pools of coral reefs. Marine DOM represents a complex, mostly unidentified assemblage of molecules, the dynamics of which have been linked to changes in the ecological functions of the benthic community such as the overgrowth of calcifying constituents by fleshy algae via a DOM and microbe-mediated process. However, limited characterization of reef DOM pools in the face of these challenges diminish the potential for adequate management and reconstruction of reefs. The goal of this dissertation is to further characterize the reef-derived dissolved organic matter pools which underpin the survival, stress-response and settlement of reef building coral holobionts.

Little attention has been given to the small-scale mechanisms relevant to microbial processes that determine the resilience of individual corals to the stress of organic matter (OM) inputs. Such mechanisms may be a critical link for predicting larger scale patterns of reef resilience. The research presented here aims to develop methods necessary to elucidate these processes and to explore the in situ responses of microbial assemblages on coral reefs experiencing persistent OM enrichment. A new method using trypsinization of coral mucus before staining for epifluorescence microscopy is described. It is then applied to a coral reef ecosystem influenced by sewage effluent to discover that corals exposed to effluent had the same number of bacteria present as reference corals; however, the size structure of the community was significantly different. Investigating the responses of microbial communities (from both the water column and corals) to OM inputs from coastal milkfish (Chanos chanos) pens, we found that the percentage of the water bacterial community attached to particles increased by more than 50-fold near the pens. This suggested a physiological or life-strategy change may be induced by such enrichment. A clonally replicated coral transplantation experiment examined the response of naïve coral-associated bacterial communities to high and low levels of pen effluent exposure. We found that the communities on corals exposed to high levels of effluent had drastically altered community compositions after five days and the abundance of bacteria in the coral mucus-tissue slurries were ~100-fold higher controls at low effluent and reference sites. We also observed a surprising resilience of these communities in that their composition and total abundance recovered by day 22. A combination of novel imaging technology (high speed laser scanning confocal microscopy on live coral) and controlled aquaria experiments were developed and used to investigate a microscale mechanism by which such resilience may occur: that corals may release ("shed") bacteria into the surrounding water as a mechanism for controlling bacterial abundance on their surface. We observed this phenomenon in real time, and quantified an increase in the rate at which corals shed bacteria as a response to OM enrichment.

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 comprehensively introduces recent important studies on coral reefs from various research fields including biology, ecology, chemistry, the earth sciences, and conservation studies. Coral reef is one of the important ecosystems characterized by high biodiversity and the beauty. Coral reefs around Japan are located at the northern limit, composed by mainly fringing reefs along archipelago, and easily impacted by human activities. Thus, coral reef studies around Japan have provided important knowledge on basic sciences and conservation studies regarding coral reef ecosystem. This book would contribute to systematic understanding of vulnerable coral reef ecosystems due to human activities in the Indo-Pacific and Caribbean regions. The conservation efforts provide good reference to graduate and undergraduate students, and researchers in marine sciences, as well as those who are involved in coral reef studies.

The monograph is based on the research and training activities in the Western Pacific Ocean Region within the umbrella of UNESCO/IOC-Sub-Commission for the Western Pacific Region. The results of these activities are compared to cases from other tropical and subtropical regions on this planet to make the knowledge applicable to global aspects of sustainability of coral reef ecosystems. In this monograph, we examine the coral reefs from viewpoint of multidisciplinary approaches, including, environmental impacts, coral biology and system ecology, biogeochemical cycles and processes that drive the material and energy flow through the food web, as well as the proxies in geochemistry that have been used to track the responses of coral reefs to the changing climate and human perturbations. Although this study is focused on the Western Pacific Ocean, the Western Pacific Ocean is so large and diverse that most reef environment types on this planet are located within it. Therefore, knowledge gained in this study is relevant to the application of coastal management in practice as well as in the teaching classes on the interactions between coral reef ecosystems with changing environments.
