Download or read book Weathering Soils Paleosols written by I.P. Martini and published by Elsevier. This book was released on 2013-10-22 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 200 years, geological scientists have used the present as a key to unlocking the past. This volume continues the tradition by exploring the processes of weathering and soil formation as indicators of the present environment of the Earth's land surface. Examined are the various ways in which this information can be used to interpret past environments which have produced the soils now preserved as paleosols. Because the surface environment of the earth may now be undergoing rapid change (the greenhouse effect), the book is a timely one for those researchers looking for evidence of analogous changes in the Earth's past. The work is divided into three major sections. The first deals with fundamental considerations of weathering, clay mineralogy and diagenesis. The second deals with the formation of soils from various starting materials and in various surficial environments. And the final section is an interpretation of paleosols. This volume provides valuable reading material for graduate and senior-undergraduate courses.
Download or read book The Terrestrialization Process written by Marco Vecoli and published by Geological Society of London. This book was released on 2010 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invasion of the land by plants (terrestrialization) was one of the most significant evolutionary events in the history of life on Earth, and correlates in time with periods of major palaeoenvironmental perturbations. The development of a vegetation cover on the previously barren land surfaces impacted on the global biogeochemical cycles and the geological processes of erosion and sediment transport. The terrestrialization of plants preceded the rise of major new groups of animals, such as insects and tetrapods, the latter numbering some 24 000 living species, including ourselves. Early land-plant evolution also correlates with the most spectacular decline of atmospheric CO2 concentration of Phanerozoic times and with the onset of a protracted period of glacial conditions on Earth. This book includes a selection of papers covering different aspects of the terrestrialization, from palaeobotany to vertebrate palaeontology and geochemistry, promoting a multidisciplinary approach to the understanding of the co-evolution of life and its environments during Early to Mid-Palaeozoic times.

Available in PDF, EPUB and Kindle. Book excerpt: Based on two decades of research, The Late Devonian Mass Extinction reviews the many theories that have been presented to explain the global mass extinction that struck the earth over 367 million years ago, considering in particular the possibility that the extinction was triggered by multiple impacts of extraterrestrial objects.
Download or read book The Great Ordovician Biodiversification Event written by Barry D. Webby and published by Columbia University Press. This book was released on 2004-04-14 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.
Download or read book The Phanerozoic Carbon Cycle written by Robert A. Berner and published by Oxford University Press. This book was released on 2004-08-19 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "carbon cycle" is normally thought to mean those processes that govern the present-day transfer of carbon between life, the atmosphere, and the oceans. This book describes another carbon cycle, one which operates over millions of years and involves the transfer of carbon between rocks and the combination of life, the atmosphere, and the oceans. The weathering of silicate and carbonate rocks and ancient sedimentary organic matter (including recent, large-scale human-induced burning of fossil fuels), the burial of organic matter and carbonate minerals in sediments, and volcanic degassing of carbon dioxide contribute to this cycle. In The Phanerozoic Carbon Cycle, Robert Berner shows how carbon cycle models can be used to calculate levels of atmospheric CO[2 and O[2 over Phanerozoic time, the past 550 million years, and how results compare with independent methods. His analysis has implications for such disparate subjects as the evolution of land plants, the presence of giant ancient insects, the role of tectonics in paleoclimate, and the current debate over global warming and greenhouse gases
Download or read book Climate Change Ocean Acidification and Sponges written by José Luis Carballo and published by Springer. This book was released on 2017-10-27 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.

Download or read book Mass Extinctions and Their Aftermath written by A. Hallam and published by Oxford University Press, UK. This book was released on 1997-09-11 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book to review all the evidence concerning both the dinosaur extinctions and all the other major extinctions - of plant, animal, terrestrial, and marine life - in the history of life. All the extinction mechanisms are critically assessed, including meteorite impact, anoxia, and volcanism. - ;Why do mass extinctions occur? The demise of the dinosaurs has been discussed exhaustively, but has never been out into the context of other extinction events. This is the first systematic review of the mass extinctions of all organisms, plant and animal, terrestrial and marine, that have occurred in the history of life. This includes the major crisis 250 million years ago which nearly wiped out all life on Earth. By examining current paleontological, geological, and sedimentological evidence of environmental changes, the cases for explanations based on climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions are all critically evaluated. -
