Book Synopsis Early Palaeozoic Biogeography and Palaeogeography by : D.A.T. Harper
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.
Book Synopsis The Evolution and Fossil Record of Parasitism by : Kenneth De Baets
Download or read book The Evolution and Fossil Record of Parasitism written by Kenneth De Baets and published by Springer Nature. This book was released on 2022-01-01 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume two focuses on the importance of direct host associations and host responses such as pathologies in the geological record to constrain the role of antagonistic interactions in driving the diversification and extinction of parasite-host relationships and disease. To better understand the impact on host populations, emphasis is given to arthropods, colonial metazoans, echinoderms, mollusks and vertebrates as hosts. In addition, novel techniques used to constrain interactions in deep time are discussed ranging from chemical and microscopic investigations of host remains, such as blood and coprolites, to the statistical inference of lateral transfer of transposons and host-parasite coevolutionary dynamics using molecular divergence time estimation.
Book Synopsis Coral Reefs at the Crossroads by : Dennis K. Hubbard
Download or read book Coral Reefs at the Crossroads written by Dennis K. Hubbard and published by Springer. This book was released on 2016-07-27 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Trace Fossils as Indicators of Sedimentary Environments by : Dirk Knaust
Download or read book Trace Fossils as Indicators of Sedimentary Environments written by Dirk Knaust and published by Newnes. This book was released on 2012-12-31 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integration of ichnological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. Mainly intended for sedimentologists, this book aims to make ichnological methods as part of facies interpretation more popular, providing an analytical review of the ichnology of all major depositional environments and the use of ichnology in biostratigraphic and sequence stratigraphic analysis. It starts with an introduction to the historical aspect of ichnology, introducing common concepts and methods, and then continues with parts treating the main depositional systems from continental, shallow-marine and deep-marine siliciclastics, and marine carbonates. The last part is dedicated to the ichnology in hydrocarbon reservoir and aquifer characterization. First overview in 25 years of the status of ichnological studies in facies reconstructions of all major depositional environments Written by a selected, well-experienced and specialized international authorship Provides easy access to the comprehensive and widespread literature

Book Synopsis A New Silurian (Llandovery, Telychian) Sponge Assemblage from Gotland, Sweden by : Freek Rhebergen
Download or read book A New Silurian (Llandovery, Telychian) Sponge Assemblage from Gotland, Sweden written by Freek Rhebergen and published by John Wiley & Sons. This book was released on 2014-02-27 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.

Keith Rigby and published by Geological Survey of Canada. This book was released on 1989 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes one of the most diverse Silurian sponge faunas known in North America. The fossils are from the Cape Phillips Formation on Baillie-Hamilton and Cornwallis islands, and are part of the distinct biogeographic realm that stretches north and west of the Transcontinental Arch. The fossils were obtained from both allochthonous and autochthonous beds that represent slope or basin margin environments of the Franklinian Geosyncline. It describes 5 new genera and 19 new species.
