Available in PDF, EPUB and Kindle. Book excerpt: Velik del slovenskega ozemlja je zgrajen iz mezozojskih, to je triasnih, jurskih in krednih karbonatnih kamnin, katerih pomemben delež sestavljajo koralni grebeni. Ti so v Sloveniji mestoma tako obsežni, da se prištevajo med največje in najbogatejše v svetu. Njihovi glavni graditelji so korale, ki jih avtorica raziskuje že vrsto let. Knjiga združuje rezultate vseh dosedanjih del in jih dopolnjuje z najnovejšimi raziskavami doma in s sodobnimi ugotovitvami v svetu. Po enotnem sistemu je predstavljenih 211 vrst koral, ki po starosti sodijo v zgornji trias, zgornjo juro ter spodnjo in zgornjo kredo.
Download or read book The History and Sedimentology of Ancient Reef Systems written by George D. Stanley Jr. and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Upper Triassic Corals and and Carbonate Reef Facies from the Martin Bridge and Hurwal Formations Wallowa Terrane Oregon written by Megan Ruth Rosenblatt and published by . This book was released on 2010 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity and abundance of Late Triassic scleractinian corals and carbonate microfacies were analyzed from the Wallowa terrane (southern Wallowa Mountains, Oregon) in order to determine regional and distant paleogeographic relationships during the Late Triassic time. Systematic identification of coral species and depositional environments between two formations in the Wallowa terrane (Summit Point Member of the Martin Bridge Formation and Excelsior Gulch of the Hurwal Formation) and one locality in the adjacent Olds Ferry terrane (Willow Spring of the Upper Huntington Formation) were used to analyze similarities between the Tethys realm (Northern Calcareous Alps) and the terranes of the North American Cordillera. The Jaccard and Dice Coefficients were used to determine similarities between the Summit Point Member, Excelsior Gulch conglomerate, and the Willow Spring conglomerate as well as previously studied terranes throughout the Late Triassic world. Results showed strong similarities (p-values less than 0.05) between the Summit Point Member and Excelsior Gulch conglomerate (Wallowa terrane). Statistical similarities between the Wallowa and Olds Ferry terrane were indicated by the Jaccard or Dice Coefficients; however, the co-occurrence of coral species (Cerioheterastraea sp. and Spongiomorpha ramosa) and associated reef biota demonstrate a strong correlation between the Excelsior Gulch conglomerate (Wallowa terrane) and the Willow Spring conglomerate (Olds Ferry terrane). Paleoecological analysis of the Summit Point Member revealed a sequence of in situ stacked patch reefs dominated by scleractinian corals, hypercalcified sponges, and calcareous solenoporacean red algae. Debris produced by physical and biological breakdown of these patch reefs shed voluminous amounts of carbonate remains into the interstitial spaces between the patches creating sediment build-up. This debris created mostly massive limestone with concentrations of reef framework mixed with rudstones and bioclastic grainstones, packstones, and wackestones. Summit Point also provides the best source for the limestone clasts of the Excelsior Gulch conglomerate. The behavior of the Summit Point reef is extremely similar to that of the Dachstein Limestone in the Northern Calcareous Alps, Austria. This discovery provides valuable paleogeographic and paleoecologic information for reef build-ups throughout the Late Triassic world.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
