John Lythgoe was one of the pioneers of the 'Ecology of Vision', a subject that he ably delineated in his classic and inspirational book published some 20 years ago [1]. At heart, the original book aimed generally to identify inter-relationships between vision, animal behaviour and the environment. John Lythgoe excelled at identifying the interesting 'questions' in the ecology of an animal that fitted the 'answers' presented by an analysis of the visual system. Over the last twenty years, however, since Lythgoe's landmark publication, much progress has been made and the field has broadened considerably. In particular, our understanding of the 'adaptive mechanisms' underlying the ecology of vision has reached considerable depths, extending to the molecular dimension, partly as a result of development and application of new techniques. This complements the advances made in parallel in clinically oriented vision research [2]. The current book endeavours to review the progress made in the ecology of vision field by bringing together many of the major researchers presently active in the expanded subject area. The contents deal with theoretical and physical considerations of light and photoreception, present examples of visual system structure and function, and delve into aspects of visual behaviour and communi cation. Throughout the book, we have tried to emphasise one of the major themes to emerge within the ecology of vision: the high degree of adaptability that visual mechanisms are capable of undergoing in response to diverse, and dynamic, environments and behaviours.

This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries. This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.

"The decline of coral ... if it continues ... will mark the end of one of the great beauties of creation and the end of a great hope that of discovering life forms hitherto unknown on the Earth ... Let us not forget that we are responsible to posterity for the preservation of the beauties of the sea as well as for those on land. We must learn how to make use of the biological and mineral resources of the oceans ... But we must also learn how to preserve the integrity and the equilibrium of that world which is so inextricably bound to our own." - Jacques Yves Cousteau, Excerpt from Life and Death in a Coral Sea, 1971 This book reports on the World Bank's 5th Annual Conference on Environmentally and Socially Sustainable Development, which focused on some of the most urgent threats facing coral reefs today, including the growing use of cyanide fishing along some of the richest reefs of the world, unsustainable trade in reef products, and constraints to effective establishment and management of marine protected areas. The proceedings stressed the need for strengthening the policy environment while adopting economic incentives and improved resource valuation techniques, informing management decisions through targeted research and monitoring, and rallying public support through environmental education and the media.

If one does not understand the biology of the coral reef, one does not understand the reef at all. So, using more than 250 illustrations and specially drawn ecological reconstructions of reef communities, Rachel Wood provides a unique evolutionary approach to the understanding of ancient coral reef ecosystems. Marine organisms have aggregated to form reefs for over 3.5 billion years--creating the largest biologically constructed feature on earth, some visible from space. However, their study has been largely descriptive. Reef Evolution, documents the fundamental biological processes and innovations which have molded the evolution of reef ecosystems and given rise to the highly complex communities found today. The appearance of clonality, the acquisition of photosymbiosis, and the radiation of predator groups are all discussed in depth. Data from the fossil record documents the evolutionary development of reef ecosystems. Although reefs only occupy a small percentage of the oceans, their importance to the marine environment is many-faceted and global. They create harbors and allow the development of shallow basins with associated mangrove or seagrass communities; they protect coastlines from erosion; are involved in the regulation of atmospheric carbon, which in turn contributes to climate control. can provide extensive oil and gas reservoirs. From a biological standpoint, however, the great significance of reefs lies in their ability to generate and maintain a substantial proportion of tropical marine biodiversity. This unique interdisciplinary approach provides students and researchers in evolution, marine biology, ecology, paleontology, biodiversity, and geology with a text that will allow them to truly understand the biological innovations which have molded the evolution of coral reefs and given rise to the highly complex communities found today.

During the late 1960s and 1970s, massive herds of poisonous crown-of-thorns starfish suddenly began to infest coral reef communities around the world, leaving in their wake devastation comparable to a burnt-out rainforest. In What is Natural?, Jan Sapp both examines this ecological catastrophe and captures the intense debate among scientists about what caused the crisis, and how it should be handled. The crown-of-thorns story takes readers on tropical expeditions around the world, and into both marine laboratories and government committees, where scientists rigorously search for answers to the many profound questions surrounding this event. Were these fierce starfish outbreaks the kind of manmade disaster heralded by such environmentalists as Rachel Carson in Silent Spring? Indeed, discussions of the cause of the starfish plagues have involved virtually every environmental issue of our time--over-fishing, pesticide use, atomic testing, rain forest depletion, and over-population--but many marine biologists maintain that the epidemic is a natural feature of coral-reef life, and ecological "balance of nature" that should not be tampered with until we know the scientific truth of the crisis. But should we search for the scientific truth before taking action? And what if an environmental emergency cannot wait for a rigorous scientific search for "the truth"? The starfish plagues are arguably one of most mysterious ecological phenomena of this century. Through the window of this singular event, What is Natural lucidly illustrates the complexity of environmental issues while probing the most fundamental questions about the relationship between man and nature.
