This volume presents a broad panorama of the current status of research of invertebrate animals considered belonging to the phylum Cnidaria, such as hydra, jellyfish, sea anemone, and coral. In this book the Cnidarians are traced from the Earth’s primordial oceans, to their response to the warming and acidifying oceans. Due to the role of corals in the carbon and calcium cycles, various aspects of cnidarian calcification are discussed. The relation of the Cnidaria with Mankind is approached, in accordance with the Editors’ philosophy of bridging the artificial schism between science, arts and Humanities. Cnidarians' encounters with humans result in a broad spectrum of medical emergencies that are reviewed. The final section of the volume is devoted to the role of Hydra and Medusa in mythology and art.

Concern about the effects of global change on our planet's future has driven much research into the last few thousand years of earth history. In contrast, this volume takes a much longer viewpoint to provide a historical perspective to recent and future global change. Over 40 international specialists investigate the reaction of life to global environmental changes, from Cretaceous times to the turn of the century. During this time earth's climate has changed from a very warm, 'greenhouse' phase with no significant ice sheets to today's 'ice-house' world. A wide spectrum of animal, plant and protistan life is discussed, encompassing terrestrial, shallow-marine and deep-marine realms. Each chapter considers a particular taxonomic group, looking first at the general picture and then focusing on more specialized aspects such as extinctions, diversity and biogeography. This volume will form an invaluable reference for researchers and graduate students in paleontology, geology, biology, oceanography and climatology.

The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea level. This volume highlights contributions from a broad range of geological sub-disciplines currently striving to understand these critical intervals of geologically rapid, global-scale changes. * Provides updated, current models for the mid-Late Devonian and Permian-Triassic mass extinction episodes * Highlights several new analytical approaches for developing quantitative datasets * Takes an integrated approach presenting datasets from a broad range of sub-disciplines

The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

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.

Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.

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.

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.

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.
