Download or read book Taphonomy written by Peter A. Allison and published by Springer. This book was released on 2010-11-03 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taphonomic bias is a pervasive feature of the fossil record. A pressing concern, however, is the extent to which taphonomic processes have varied through the ages. It is one thing to work with a biased data set and quite another to work with a bias that has changed with time. This book includes work from both new and established researchers who are using laboratory, field and data-base techniques to characterise and quantify the temporal and spatial variation in taphonomic bias. It may not provide all the answers but it will at least shed light on the right questions.

Download or read book Biology and Evolution of the Mollusca Volume 2 written by Winston Frank Ponder and published by CRC Press. This book was released on 2020-02-14 with total page 1091 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides individual treatments of the major molluscan taxa. Each chapter provides an overview of the evolution, phylogeny and classification of a group of molluscs, as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record and aspects of their natural history. The book is illustrated with hundreds of colour figures. In both volumes, concepts are summarised in colour-coded illustrations. Key selling features: Comprehensively reviews molluscan biology and evolutionary history Includes a description the anatomy and physiology of anatomical systems Up to date treatment with a comprehensive bibliography Reviews the phylogenetic history of the major molluscan lineages

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.

These preliminary steps in the development of a new species can only be observed in living organisms, and in our laboratory methods of studying dead organisms we may fail to distinguish species that are clearly distinct in habits, functional activities and powers of adaption from their resemblance in external or morphological characters. In the geographic distribution of species there must be a balance of organisms in conformity with the mutual needs of competing species under the prescribed conditions, as is strikingly illustrated in the results of the introduction of the mongoose in the island of Jamaica. (V. Science, Vol. 5, p. 15, Jan. 1, 1897.) With the decline and final disappearance of the discomfited species ' in the struggle for existence from their inability to adapt themselves to the changed conditions they have aided to bring about, there must be an equivalent readjustment of t-he habits and essential requirements of the fittest to survive to establish harmonious relations with their fellows and the resulting changes in their environment. The reaction of less favored species to the sum of the influences of their environment and their ultimate decline and disappearance should not be overlooked in the evolution of new species, as the plasticity of organization _and powers of adaptation to changing conditions are intensified in the survivors by their exercise, and every element of change tends to a further divergence in functional activities... From the point of view here outlined the importance of systematic local biological surveys for the solution of problems in evolution cannot be too emphatically urged. The field naturalist should not, however, limit his observations to the identification and...
