Book Description
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.

Book Description
Decades of isolation from tourism and development have left Cuba’s coral reefs among the most pristine in the world, an “exceptionalism” that stands in stark contrast to the island nation’s poverty and political situation. Famed diver/photographer Robert “Snorkel Bob” Wintner showcases these magnificent reefs with his astounding underwater images, while also capturing terrestrial life in the cities and villages of the island nation. Reef Libre is not a travelogue, but asks the big questions after a lifetime of isolation—can Cuba’s reefs still thrive? Nearly 400 stills, a compelling narrative, and a DVD capture this delicate time in reef history. Reef Libre: The Movie is a mini-documentary which encompasses this pivotal moment—from the streets to the reefs. To watch the trailer for Reef Libre: The Movie, click here!

Book Description
From the Preface: The chapters of this book contain contributions from an international group of specialists. They address some important themes in both modern and ancient reef systems. Some chapters contain `snapshots' of reefs of particular intervals, while others touch on relevant themes of both modern and ancient reefs - themes that weave their way through reefs of all ages. This book opens and sets the stage with an introduction to both modern and ancient reefs and reef ecosystems. This chapter is also intended as a basic introduction for students, general geologists, and professionals or others who may be unfamiliar with reefs and reef ecosystems. The chapter addresses the living coral reef ecosystem, stressing among other relevant factors, the importance of ecological and physical interactions between the organisms and their environment. The chapter also addresses mass extinction and provides a general overview of the history of reefs.

Book Description
Islands have captured the imagination of scientists and the public for centuries—unique and rare environments, their isolation makes them natural laboratories for ecology and evolution. This authoritative, alphabetically arranged reference, featuring more than 200 succinct articles by leading scientists from around the world, provides broad coverage of all the island sciences. But what exactly is an island? The volume editors define it here as any discrete habitat isolated from other habitats by inhospitable surroundings. The Encyclopedia of Islands examines many such insular settings—oceanic and continental islands as well as places such as caves, mountaintops, and whale falls at the bottom of the ocean. This essential, one-stop resource, extensively illustrated with color photographs, clear maps, and graphics will introduce island science to a wide audience and spur further research on some of the planet's most fascinating habitats.

Book Description
WHAT IS BEHIND THE STRANGE PHENOMENA AT OUR WORLD's ANCIENT SITES? Haunted Spaces, Sacred Places is a fascinating and thoroughly researched exploration of the archaeology, legends, and modern mysteries of 32 ancient places throughout the world - from the mysterious megaliths of Britain and Ireland, the haunted tombs of the Etruscans, and the Pagan origins of Germany's Aachen Cathedral to the ancient Native American city of Cahokia, the enigmatic Cambodian Temple of Angkor Wat, and the sacred Aboriginal rock formation of Uluru. Why are strange phenomena so often connected with these ancient sites? Are certain sacred places somehow able to generate or attract paranormal phenomena? Or can such events be explained in terms of modern myth and contemporary folklore? What can the legends and folklore of ancient places throughout the world reveal to us about the beliefs and ideas of our ancient ancestors? These are just some of the questions answered in Brian Haughton's enthralling book.
