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.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cretaceous corals (Anthozoa, Scleractinia) of the Huetamo region of southwestern Mexico, an area in the tectonically problematic Guerrero terrane, are investigated for the first time. This study provides a detailed, modern taxonomic foundation for future work on Mexican Cretaceous corals. Thirty-nine species are described and illustrated: 20 from the lower Aptian Cumburindio Formation, one from lower Aptian strata of the San Lucas Formation, and 18 from the upper Albian-lower Cenomanian upper member of the Mal Paso Formation. At the species level, the coral faunas from these formations are entirely different from each other. Of the 21 species from the lower Aptian, three are described as new: Saltocyathus cumburindioensis n. sp., Actinaraea michoacanensis n. sp, and Thamnarea hornosensis n. sp. About 50 percent of the lower Aptian coral species have been reported previously from pre-Albian strata in the European region. This faunal similarity is the strongest geographic affinity recognized in this study. Of the 18 coral species from the upper Albian-lower Cenomanian, 11 are described as new, whereas another one of these species recently has been described and designated as the type species of a newly recognized dendrophylliid genus, Blastozopsammia guerreroterion Filkorn and Pantoja-Alor, 2004. The 11 coral species from the upper Albian-lower Cenomanian herein described as new are: Actinastrea chumbitaroensis n. sp., Preverastraea coatlicuae n. sp., Preverastraea tocae n. sp., Latiphyllia mexicana n. sp., Thecosmilia guerreroensis n. sp., Mycetophyllopsis azteca n. sp., Orbignygyra? incognita n. sp., Thalamocaeniopsis mexicanensis n. sp., Thamnasteria tonantzinae n. sp., Paracycloseris effrenatus n. sp., and Ovalastrea malpaso n. sp. Analogies with extant corals indicate that most of the coral species from the Cretaceous formations of southwestern Mexico were zooxanthellate, hermatypic, reef-building species. Associations of scleractinian corals and rudist bivalves were observed at three localities, two in the Cumburindio Formation and one in the Mal Paso Formation. The two occurrences in the Cumburindio Formation are: an association of a large species of ramose, microsolenid coral, Thamnarea hornosensis n. sp., preserved in situ along with valves of the rudists Praecaprina and Caprina at the exposures in the Arroyo Los Hornos, near Turitzio; and a diverse assemblage of reef corals that conformably overlies a bed primarily composed of valves of the rudist Amphitriscoelus near the top of the stratigraphic section at the Loma de San Juan, Turitzio, Michoacán. The coral and rudist association in the Mal Paso Formation involves a diverse assemblage of reef corals and the rudists Radiolites and Mexicaprina within an interval near the top of the stratigraphic section that is exposed at a locality in the state of Guerrero, just north of Chumbítaro, Michoacán. None of these specific kinds of coral and rudist associations has been recognized previously at any other localities.

Book excerpt: Excerpt from The Eocene and Lower Oligocene Coral Faunas of the United States: With Descriptions of a Few Doubtfully Cretaceous Species In the winter of 1892, while a student at Harvard University, I began a study of the Eocene corals of the United States, and have continued it, with considerable interruption, during six years. The study Of corals presents peculiar difficulties. The classification depends to a large extent upon minute and Obscure structures that are fre quently destroyed in fossil specimens; and the system of classification, as so many Of the later students of these organisms have pointed out, is thor oughly unsatisfactory, but as yet no good system which can replace the old one has been proposed, although recent investigators have accumulated much valuable data that will probably serve as the foundation fora better and more natural system in the near future.

Available in PDF, EPUB and Kindle. Book excerpt: The health status and future of tropical coral reefs, as tourist destinations, are regularly subjected to media coverage. Many documentaries recognize the natural beauty and biological richness of the Australian Great Barrier Reef and French Polynesian lagoons, but point to the equally significant risk that would result from current global warming and human-made hazards. The future of coral reefs is usually a matter of death foretold, real or purely imaginary. In this context, it has become necessary to differentiate between what is falling within reality of scientific facts or fantasy. To this end, the present general review, in the expert translation of Charlotte Fontan aims at: (1) defining the conditions and life requirements of reefbuilding corals; (2) the history of corals along with that of a number of associated, skeletal organisms involved in reef building since the very beginning, i.e. the last 540 million years, including the ups and downs they have experienced; (3) giving special reference to the development patterns of recent and modern reefs; (4) projecting corals and reefs into a still unknown future. Understanding how corals and reefs have originated, how they have been able to face the major biological crises which have punctuated the Earth’s history, how they have survived is a prerequisite to better gain a significant picture of their future.
