250 Years of Industrial Consumption and Transformation of Nature: Impacts on Global Ecosystems and Life


Book Description

Anthropogenic changes in the environment, caused by 250 years of economic growth and utilization of fuel and mineral resources, have considerably impacted the natural environment. The resulting physical and chemical alterations to the Earth's sphere and our adaptive responses in the biosphere are detailed in this reference book. Readers will learn about concepts relevant to Earth’s history, the evolution of life, economy, ecology, environmental history, biology, and medicine and how these concepts can be linked to environmental change. The scope of this interdisciplinary work entails to convey the true degree of responsibility for the universal consequences of ecosystem degradation resulting from industrial processing, human consumption and the transformation of natural sites due to industrialization and urbanization. Topics covered in the book include: -ecosystem transformations by natural and anthropogenic forces -the Anthropocene epoch -a short history of industrialization -environmental sites and the impact of socio-economic influences -the current environmental crisis, This textbook is intended for graduate students in economics, civil engineering, architecture, agronomics, forestry, technical and mining sciences, political sciences, business studies and humanities. General readers who wish to understand the basic philosophy behind environmental studies and their relation to human activity can also benefit from this book.

Provides a comprehensive and accessible one-stop shop for information on the subject of geology, explaining methodologies and technical jargon used in the field Highlights connections between geology and other physical and biological sciences, tackling research problems that span multiple fields Fills a critical gap of information in a field that has seen significant progress in past years Presents an ideal reference for a wide range of scientists in earth and environmental areas of study




Evolutionary Catastrophes


Book Description

Mass extinction and cataclysmic volcanic activity: will fascinate everyone interested in the history of life and death on our planet.




Mammalian Paleoecology


Book Description

What can the interactions of ancient mammals and their environments tell us about the present—and the future? Classic paleontology has focused on the study of fossils and the reconstruction of lineages of extinct species. But as diverse fossils of animals and plants were unearthed and catalogued, it became possible to reconstruct more elaborate ecosystems, tying together plants, animals, and geology. By the second half of the twentieth century, this effort gave birth to the field of paleoecology: the study of the interactions between organisms and their environments across geologic timescales. In Mammalian Paleoecology, Felisa Smith broadly considers extinct mammals in an ecological context. Arguing that the past has much to teach us and that mammals, which display an impressive array of diverse life history and ecological characteristics, are the ideal organism through which to view the fossil record, Smith • reviews the history, major fossil-hunting figures, and fundamental principles of paleoecology, including stratigraphy, dating, and taphonomy • discusses the importance of mammal body size, how to estimate size, and what size and shape reveal about long-dead organisms • explains the structure, function, and utility of different types of mammal teeth • highlights other important methods and proxies used in modern paleoecology, including stable isotopes, ancient DNA, and paleomidden analyses • assesses nontraditional fossils • presents readers with several case studies that describe how the fossil record can help inform the scientific discussion on anthropogenic climate change Mammalian Paleoecology is an approachable overview of how we obtain information from fossils and what this information can tell us about the environments of the distant past. It will profoundly affect the way paleontologists and climatologists view the lives of ancient mammals.




Mantle Convection and Surface Expressions


Book Description

A multidisciplinary perspective on the dynamic processes occurring in Earth's mantle The convective motion of material in Earth's mantle, powered by heat from the deep interior of our planet, drives plate tectonics at the surface, generating earthquakes and volcanic activity. It shapes our familiar surface landscapes, and also stabilizes the oceans and atmosphere on geologic timescales. Mantle Convection and Surface Expressions brings together perspectives from observational geophysics, numerical modelling, geochemistry, and mineral physics to build a holistic picture of the deep Earth. It explores the dynamic processes occurring in the mantle as well as the associated heat and material cycles. Volume highlights include: Perspectives from different scientific disciplines with an emphasis on exploring synergies Current state of the mantle, its physical properties, compositional structure, and dynamic evolution Transport of heat and material through the mantle as constrained by geophysical observations, geochemical data and geodynamic model predictions Surface expressions of mantle dynamics and its control on planetary evolution and habitability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.




The Worst of Times


Book Description

260 million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst--the end-Permian extinction--wiping out nearly every species on the planet. This book delves into the mystery behind these extinctions and sheds light on the fateful role the primeval supercontinent, known as Pangea, may have played in causing these global catastrophes. Drawing on the latest discoveries as well as his own field expeditions to remote corners of the world, Paul Wignall reveals what scientists are only now beginning to understand about the most prolonged period of environmental crisis in Earth's history. He describes how a series of unprecedented extinction events swept across the planet in a span of eighty million years, rapidly killing marine and terrestrial life on a scale more devastating than the dinosaur extinctions that would come later. Wignall shows how these extinctions--some of which have only recently been discovered--all coincided with gigantic volcanic eruptions of flood basalt lavas that occurred when the world's landmasses were united into a single vast expanse. Unraveling one of the great enigmas of ancient Earth, this book also explains how the splitting apart of Pangea into the continents we know today ushered in a new age of vibrant and more resilient life on our planet.--Adapted from book jacket.




The Late Triassic World


Book Description

This volume presents the latest science on all significant geological and paleontological aspects of the Earth during the Late Triassic Period. Rather than presenting a collection of narrowly focused research papers, the volume consists of a series of peer-reviewed chapters on specific aspects of the Late Triassic world (e.g., tectonics, magmatism, paleobotany, climate, etc.), all authored by experts in the subject of their respective chapters. Each chapter reviews and summarizes the latest findings in these fields and also includes a review of the pertinent literature. The author list is very broadly international and forms a veritable who’s who of expertise in these fields. The book is loosely organized to present the physical aspects of Earth during the Late Triassic at the outset, followed by the paleontological aspects. The latter section is further organized to present the record of the marine environment first before moving onto land, with fauna followed by flora. The volume closes with a review of the end-Triassic extinctions.
