Coral reefs have shaped the surface of our planet far more than has any other ecosystem. They are dynamic systems, producing limestone at the rate of 400-2,000 tons per hectare per year, and influencing the chemical balance of the world's oceans. Coral reefs have been around since before the prairies or other ecosystems of flowering plants existed, yet they vanish about a million years before other groups of organisms each time there is a global mass extinction. They return after each catastrophe, however, following a long period of absence. Although coral reefs are the most productive communities in the sea, the fisheries of coral reefs are among the most vulnerable to overexploitation. Despite having the power to create the most massive structures in the world made by living creatures (including man), the thin veneer of living tissue of coral reef is particularly sensitive to natural disturbances and effects of human activities. Coral reefs are the first to go during periods of climate change, but they have always come back. This combination of attributes, creative power and fragility, resilience and sensitivity, makes management of coral-reef systems a challenge to science. Over 70% of the coral reefs in the Caribbean and Asian waters have been degraded, and perhaps a third of the 400 species of corals in Japanese waters are in danger of local extinction unless effective coastal management practices are established. This book presents what is known about factors that shift the balance between accretion and erosion, recruitment and mortality, stony corals and filamentous algae, recovery and degradation--the life and death of coral reefs. Insight into the factors controlling the direction of these processes is essential for appropriate management decisions.

One of the most dire consequences of global climate change for coral reefs is the increased frequency and severity of mass coral bleaching events. This volume provides information on the causes and consequences of coral bleaching for coral reef ecosystems, from the level of individual colonies to ecosystems and at different spatial scales, as well as a detailed analysis of how it can be detected and quantified. Future scenarios based on modelling efforts and the potential mechanisms of acclimatisation and adaptation are reviewed. The much more severe coral bleaching events experienced on Caribbean coral reefs (compared with those of the Indo-Pacific) are discussed, as are the differences in bleaching susceptibility and recovery that have been observed on smaller geographic scales.

Eine verbotene Liebe in einem dunklen Königreich! Seit Generationen heiraten die Prinzen von Ilara das schönste Mädchen der abgelegenen Insel Varenia. Alle Mädchen träumen davon, als Prinzessin Ilaras auserwählt zu werden, auch die siebzehnjährige Nor. Nor glaubt jedoch, dass ihre hübschere Zwillingsschwester Zadie den Kronprinzen heiraten wird, während sie selbst auf der Insel zurückbleiben muss. Als sich Zadie allerdings bei einem Tauchgang im Meer verletzt, wird Nor an ihrer Stelle nach Ilara geschickt. Dort trifft sie nicht nur auf ihren zukünftigen Ehemann, den feindseligen Prinzen Ceren, sondern auch auf dessen charmanten jüngeren Bruder Talin – und entdeckt eine Verschwörung, die ihre Heimatinsel zerstören könnte.

Deep-water coral reefs are found along large sections of the outer continental shelves and slopes of Europe, from North Cape to the Gulf of Cadiz, and because they also occur along the Atlantic seaboard of USA, the Gulf of Mexico, off Brazil, in the Mediterranean, and off New Zealand, they are currently being targeted by international groups of marine scientists. They have become popular and opportune deep-water research targets because they offer exciting frontier exploration, combined with a whole plethora of modern scientific methods, such as deep-sea drilling, sampling, remote control surveying and documentation. Furthermore they represent timely opportunities for further developments within the application of geochemistry, stable isotope research, bacterial sciences, including DNA-sequestering, and medical research (search for bioactive compounds). The Integrated Ocean Drilling Program (IODP) has arranged a deep-sea scientific drilling campaign on giant carbonate banks off Ireland. Because the reefs currently defy traditional marine-ecological theories, they represent future research opportunities and will enjoy scientific scrutiny for many years to come.

The local diversity and global richness of coral reef fishes, along with the diversity manifested in their morphology, behaviour and ecology, provides fascinating and diverse opportunities for study. Reflecting the very latest research in a broad and ever-growing field, this comprehensive guide is a must-read for anyone interested in the ecology of fishes on coral reefs. Featuring contributions from leaders in the field, the 36 chapters cover the full spectrum of current research. They are presented in five parts, considering coral reef fishes in the context of ecology, patterns and processes, human intervention and impacts, conservation, and past and current debates. Beautifully illustrated in full-colour, this book is designed to summarise and help build upon current knowledge and to facilitate further research. It is an ideal resource for those new to the field as well as for experienced researchers.

Butterflyfishes of the family Chaetodontidae are conspicuous members of almost all tropical reefs. These colorful fishes have attracted a great deal of attention from both the scientific community and especially the aquarium fish industry. At first one is tempted to say that butterflyfishes are abundant worldwide, but the evidence does not support this statement. The biomass of chaetodontids on reefs may range from 0.02-0.80%, and in terms of numbers they comprise only 0.04-0.61 % of the individuals on the reef. Yet in spite of these relatively small numbers they have been extensively studied. A quick census shows some 170 articles on or about butterfly fishes, with 78% of them being published since the 1970's. Along with the cichlids and damselfishes they might be one of the most studied and well published family of tropical fishes. Why then have chaetodontids attracted so much attention? The butterflyfishes are mostly shallow water inhabitants that are approachable and easily recognizable, making their study very feasible. Their bright coloration has provoked many hypotheses but has posed more questions about coloration than it has provided answers. And despite their apparent overall morphological similarity, their highly structured and varied social systems have made them an ideal model for such studies. The reasons for choosing these organisms are indeed as diverse as the studies themselves.

In this book, contributors from diverse backgrounds take a first step toward an integrated view of reefs and the significance of their recent decline. More than any other earth system, coral reefs sit at a disciplinary crossroads. Most recently, they have reached another crossroads - fundamental changes in their bio-physical structure greater than those of previous centuries or even millennia. Effective strategies to mitigate recent trends will require an approach that embraces the myriad perspectives from across the scientific landscape, but will also need a mechanism to transform scientific understanding into social will and political implementation.

Providing a synthesis of basic and applied research, The Everglades, Florida Bay, and Coral Reefs of the Florida Keys: An Ecosystem Sourcebook takes an encyclopedic look at how to study and manage ecosystems connected by surface and subsurface water movements. The book examines the South Florida hydroscape, a series of ecosystems linked by hydrology in a region of intense human development and profound modifications to the natural environment. The book presents scientific studies in the South Florida Hydroscape, discusses policy and management by government and nonprofit groups, and explores how the whole watershed approach must be used to successfully protect coral reefs. The contributions range from the traditional to the controversial, questioning current management schemes and summarizing the results of state-of-the-art research. Billions of dollars, countless man-hours, and innumerable resources have been spent studying the various South Florida ecosystems and how they are linked. The Everglades, Florida Bay, and Coral Reefs of the Florida Keys: An Ecosystem Sourcebook shows you how the principles learned in this region can be applied to other tropical and subtropical hydroscapes.
