Vertical Reefs

On a clear night, the bright lights of oil platforms sparkle in the Gulf of Mexico. Thousands of these platforms off the coasts of Texas and Louisiana play an important role in the lives of underwater species who find food, shelter, and permanent homes in the ecosystem created by these big, three-dimensional structures standing on the flat sea floor. They may also play lesser-known roles “above the waves” in the migration of birds and even insects. Tapping into years of diving experience, marine biologist Mary Wicksten looks at the inhabitants and visitors of these “vertical reefs”, explaining how life arrives on the platforms, what species settle and stay (like barnacles), and which ones visit then disappear (like silky sharks). She looks at how different life forms take up occupancy from the surface downward, and she shows how these communities vary on nearshore and deepwater platforms. While most people may never experience the undersea world of oil platforms, this book will bring a better understanding of it to any teacher, beachgoer, angler, diver, or coastal resident who ever wondered what was going on beneath those far-off lights.

Cold-water corals form reef structures in continental margin and seamount settings world-wide, making them more wide-spread and abundant than shallow-water reefs. Their role in these ecosystems is no less important than the influence that shallow-water coral reefs have on tropical systems. They create habitat structure, host endemic species, enhance elemental cycling, alter current flow, sequester carbon, and provide many other ecosystem services that we are just beginning to understand. The rapidly evolving state of knowledge of cold-water and deep-sea coral reefs has not been compiled in over 10 years. This volume synthesizes recent and historical information, reveals new findings from reefs that have been discovered only recently, and presents key avenues for future research. We are on the cusp of understanding the critical role that cold-water coral reefs play in the world’s oceans, and this book lays the foundation on which this knowledge will be built in the future.

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

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.

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.

Most of the coral reefs of the American continent: the Brazilian waters, the Caribbean Sea and the eastern Pacific Ocean are in Latin American countries, the subject of this book. For the first time, information on coral reefs of such a vast region is mined from reports, obscure journals, university thesis and scientific journals, summarized and presented in a way both accessible and informative for the interested reader as well as for the coral reef expert. The chapters of the book, divided by country and ocean, were written by either scientists from the countries or by those that know the area well. Reefs not documented in the past are described in detail here, including location maps. The natural and anthropogenic impacts affecting the reefs are presented, as well as sections on management, conservation and legislation in each country. Nineteen chapters, plus an introduction, present information of coral reefs from Brazil to Mexico, and from Chile to Cuba.

This book provides a comprehensive and up-to-date review of the ecology of coral reef fishes presented by top researchers from North America and Australia. Immense strides have been made over the past twenty years in our understanding of ecological systems in general and of reef fish ecology in particular. Many of the methodologies that reef fish ecologists use in their studies will be useful to a wider audience of ecologists for the design of their ecological studies. Significant among the impacts of the research on reef fish ecology are the development of nonequilibrium models of community organization, more emphasis on the role of recruitment variability in structuring local assemblages, the development and testing of evolutionary models of social organization and reproductive biology, and new insights into predator-prey and plant-herbivore interactions.

A study of coral reefs is of great theoretical and practical importance in biology, geology, ecology, and for understanding the history of ocean basins and seacoasts. As a biological formation, the reef represents one of the rare natural marine ecosystem models with the highest biological productivity. Contemporary reef systems exert an extremely important influence on the overall biological control of the World Ocean. Coral reefs have been recognized as one of the richest natural ecosystems and could be considered a prototype of a highly productive marine economy.
