A Multi Disciplinary Evaluation Of The Hybrid Anemonefish Amphiprion Leucokranos

Ashton Gainsford's research questioned what constitutes a species, highlighting the importance of animal behaviour to the outcomes of hybridization, a common and significant evolutionary phenomena where closely related species interbreed. Her research on coral reef fish using behaviour and genetic tools provides novel insights into the ecology and evolution of species.

Michael L. Arnold offers an exploration of the evolutionary process of natural hybridisation, and presents data from various sources that support the paradigm of natural hybridisation as an important evolutionary process.

Staghorn corals (genus Acropora) are the most obvious and important corals on coral reefs throughout the world, providing much of the beauty and variety seen on the reefs. This invaluable reference tool is the first major review of Acropora in over 100 years. It assesses all the known species worldwide, describing each in detail and illustrating the range of variability of form with habitat and geographic location. The classification, evolution and worldwide distribution of all species are reviewed and illustrated with colour plates, full page black and white plates and distribution maps. Details of the general biology of staghorn corals are discussed and illustrated. The book is complemented by a CD-ROM, Staghorn Corals of the World: A Key to Species of Acropora, containing a LucID-based key to all species of Acropora and a photo library of type specimens from museums around the world. Special Offer: Staghorn Corals of the World book and CD-ROM set for only $220.00.

This book contains a long-overdue treatment of the marine fish fauna of the region extending from the central Gulf of California, southward to Ecuador, including the offshore Revillagigedos, Cocos, and Galapagos island groups. Lavishly illustrated, it includes coverage of 680 species.

As concerns about the change in global climate and the loss of biodiversity have mounted, attention has focused on the depletion of the ozone layer and the destruction of tropical rainforests. But recently scientists have identified another seriously endangered ecosystem: coral reefs. In Corals in Space and Time, J.E.N. Veron provides a richly detailed study of corals that will inform investigations of these fragile ecosystems. Drawing on twenty-five years of research, Veron brings together extensive field observations about the taxonomy, biogeography, paleontology, and biology of corals. After introducing coral taxonomy and biogeography, as well as relevant aspects of coral biology for the non-specialist, he provides an interpretation of the fossil record and paleoclimates, an analysis of modern coral distribution, and a discussion of the evolutionary nature and origins of coral species. Revealing a sharp conflict between empirical observations about the geographical variation within species, Veron introduces a non-Darwinian theory of coral evolution. He proposes that the evolution of coral species is driven not primarily by natural selection, but by constantly shifting patterns of ocean circulation, which produce changing variations of genetic connectivity. This mechanism of speciation and hybridization has far-reaching consequences for the study of all types of corals and potentially many other groups of organisms as well.

A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
