The Trace Fossil Record Of Major Evolutionary Events

by M. Gabriela Mángano, The Trace Fossil Record Of Major Evolutionary Events Books available in PDF, EPUB, Mobi Format. Download The Trace Fossil Record Of Major Evolutionary Events books, This volume addresses major evolutionary changes that took place during the Mesozoic and the Cenozoic. These include discussions on major evolutionary radiations and ecological innovations on land and at sea, such as the Mesozoic marine revolution, the Mesozoic radiation of vertebrates, the Mesozoic lacustrine revolution, the Cenozoic radiation of mammals, the evolution of paleosol biotas, and the evolution of hominins. The roles of mass extinctions at the end of the Triassic and at the end of the Cretaceous are assessed. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.

Epigenetic Mechanisms Of The Cambrian Explosion

by Nelson R. Cabej, Epigenetic Mechanisms Of The Cambrian Explosion Books available in PDF, EPUB, Mobi Format. Download Epigenetic Mechanisms Of The Cambrian Explosion books, Epigenetic Mechanisms of the Cambrian Explosion provides readers with a basic biological knowledge and epigenetic explanation of the biological puzzle of the Cambrian explosion, the unprecedented rapid diversification of animals that began 542 million years ago. During an evolutionarily instant of ~10 million years, which represents only 0.3% of the time of existence of life on Earth, or less than 2% of the time of existence of metazoans, all of the 30 extant body plans, major animal groups (phyla) and several extinct groups appeared. The work helps address this phenomena and tries to answer remaining questions for evolutionary biology, epigenetics, and scientific researchers. The book recognizes and presents objective representations of alternative theories for epigenetic evolution in this period, with the author drawing on his epigenetic theory of evolution to explain the causal basis of the Cambrian explosion. Both empirical evidence and theoretical arguments are presented in support of this thought-provoking epigenetic theory. Explains the Cambrian explosion from an entirely epigenetic view Takes a causal rather than descriptive approach to the phenomenon Allows for a broad readership, including those with only a basic biological knowledge, while maintaining scientific rigor

Soils Of The Past

by Gregory J. Retallack, Soils Of The Past Books available in PDF, EPUB, Mobi Format. Download Soils Of The Past books, A student-friendly textbook that describes ancient soils, how they may be identified, and their use in paleoenvironmental reconstruction Ancient soils contain vital mineralogical, geochemical, textural, and paleontological information about the continental environments in which they formed. Advances in isotope geochemistry and sequence-stratigraphic models allow evermore detailed reconstructions of environmental change from paleosols, and new insights into such diverse topics as atmospheric chemistry, global change, paleoecology, geobiology and mass extinction. This book educates readers about the field of paleopedology and how it remains a key area of investigation for geologists and environmental scientists seeking to learn about, and reconstruct, the condition and evolution of paleoenvironments. Presented in three sections—Soils and Palesols; Factors in Soil Formation; and Fossil Record of Soils—Soils of the Past: An Introduction to Paleopedology describes the main types of ancient soil, procedures for identifying and studying them, their classification and, most significantly, a wide array of examples of how paleosols have been used for paleoenvironmental reconstruction. The book is an excellent reflection of the current state of knowledge and can be widely adopted over many disciplines. All chapters have been revised and updated to reflect advances in soil science in the last two decades New tables display a wealth of new data added since the 2nd edition published in 2001 New figures have been added and line art has been redrawn to improve clarity and promote understanding References have been updated throughout Soils of the Past, 3rd Edition is written for advanced undergraduates studying paleopedology as part of a degree in geology, environmental science, or physical geography, and for interested professional earth scientists.

Ichnoentomology

by Jorge Fernando Genise, Ichnoentomology Books available in PDF, EPUB, Mobi Format. Download Ichnoentomology books, This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.

Plant Life

by Roland Ennos, Plant Life Books available in PDF, EPUB, Mobi Format. Download Plant Life books, There are almost one third of a million species of plants which range in form from unicellular algae a few microns in diameter to gigantic trees that can grow to a height of 100 meters. Plant Life makes sense of the bewildering diversity of plants by treating them not just as photosynthetic factories, but as living organisms that are the survivors of millions of years of evolutionary struggle. The book examines plants from an evolutionary perspective to show how such a wide range of life forms has evolved and continues to thrive. The book is divided into three main sections. The first introductory section sets out the necessary background of evolutionary and taxonomic theory and introduces a classification of living plants based on the ways in which they have evolved. The second part investigates how the challenges of life in the water and on land have led to the evolution of the major taxonomic groups of the plants, and describes the key adaptations that have contributed to the success of each group. The final section shows how the contrasting environments of the world's major climatic zones have led to the evolution of such different floras as those of tropical rainforests, prairies and deserts. This section introduces a fascinating range of plants with ingenious and often bizarre methods of survival and reproduction. The book is enriched by detailed case studies, points for discussion and suggestions for further investigation. In addition, extensive color plates and line drawings bring the world of plants vividly to life. Clear classification charts and a full glossary are also useful. Plant Life is an essential elementary text for undergraduate students and should prove a breath of fresh air for jaded botanists who are accustomed to the traditional taxonomic grind through the plant kingdom. New, environmental approach in keeping with modern course content. Beautifully written in a clear, concise and accessible style. Extensive colour plates, electron micrographs and line drawings bring the world of plants vividly to life. Uses carefully chosen examples of species in each group, so that students are not overwhelmed with excessive information and species lists. Discussion questions at the end of chapters encourages further reading and provides essay topics for teachers. Clear classification charts and a full glossary provide useful material for revision.

Download Continuity And Discontinuity In The Peopling Of Europe books, Since the Western world first became aware of the existence of Neanderthals, this Pleistocene human has been a regular focus of interest among specialists and also among the general public. In fact, we know far more about Neanderthals than we do about any other extinct human population. Furthermore, over the past 150 years no other palaeospecies has been such a constant source of discussion and fierce debate among palaeoanthropologists and archaeologists. This book presents the status of our knowledge as well as the methods and techniques used to study this extinct population and it suggests perspectives for future research.

Paleolimnology

by Andrew S. Cohen, Paleolimnology Books available in PDF, EPUB, Mobi Format. Download Paleolimnology books, This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
