Download or read book The Palynology and Micropalaeontology of Boundaries written by Alwynne Bowyer Beaudoin and published by Geological Society of London. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.
Download or read book Effects of Past Global Change on Life written by Panel on Effects of Past Global Change on Life and published by National Academies Press. This book was released on 1995-01-15 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditions--or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient life--and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening others--including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative tools--and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

Download or read book A Global Synthesis of the Ordovician System Part 1 written by D.A.T. Harper and published by Geological Society of London Special Publications. This book was released on 2023-06-07 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.

Download or read book Early Palaeozoic Biogeography and Palaeogeography written by D.A.T. Harper and published by Geological Society of London. This book was released on 2014-01-27 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.
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.
Download or read book The Geology of Central Europe written by Tom McCann and published by Geological Society of London. This book was released on 2008 with total page 806 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 focuses on the evolution of Central Europe from the Precambrian to the Permian, a dynamic period which traces the formation of Central Europe from a series of microcontinents that separated from Gondwana through to the creation of Pangaea. Separate summary chapters on the Cadomian, Caledonian and Variscan orogenic events as well as on Palaeozoic magmatism provide an overview of the tectonic and magmatic evolution of the region. These descriptions sometimes extend beyond the borders of Central Europe to take in the Scottish and Irish Caledonides as well as the Palaeozoic successions in the Baltic region.
