Available in PDF, EPUB and Kindle. Book excerpt: Carbon Isotope Techniques deals with the use of carbon isotopes in studies of plant, soil, and aquatic biology. Topics covered include photosynthesis/translocation studies in terrestrial ecosystems; carbon relationships of plant-microbial symbioses; microbe/plant/soil interactions; and environmental and aquatic toxicology. Stable carbon isotope ratios of natural materials are also considered. Comprised of 15 chapters, this book begins with an introduction to radiation-counting instruments used in measuring the radioactivity in soil and plant samples containing carbon-14. The discussion then turns to the basic methods of 14C use in plant science, highlighted by three examples of applications in the field of plant physiology and ecology. Subsequent chapters explore the use of carbon isotope techniques for analyzing the carbon relationships of plant-microbial symbioses; the interactions of microbes, plants, and soils; and the degradation of herbicides and organic xenobiotics. Carbon dating and bomb carbon are also described. The final section is devoted to the uses and procedures for 13C and 11C. This monograph is intended for advanced undergraduate or graduate students, as well as generalist scientists who have not previously used radioisotopes or stable isotopes in their research.

Download or read book Organic Geochemistry written by Geoffrey Eglinton and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, the subject matter encompassed by the title of this book was largely limited to those who were interested in the two most economically important organic materials found buried in the Earth, namely, coal and petroleum. The point of view of any discussions which might occur, either in scientific meetings or in books that have been written, was, therefore, dominated largely by these interests. A great change has occurred in the last decade. This change had as its prime mover our growing knowledge of the molecular architecture of biological systems which, in turn, gave rise to a more legitimate asking of the question: "How did life come to be on the surface of the Earth?" A second motivation arose when the possibilities for the exploration of planets other than the Earth-the moon, Mars, and other parts of the solar system-became a reality. Thus the question of the possible existence of life elsewhere than on Earth conceivably could be answered.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the taxonomy, biology, sedimentation, and carbonate geochemistry of modern species. Students, early career and advanced scientists alike will profit from a broad synthesis of the current understanding of planktic foraminifers as an ecological indicator, biogeochemical factories, and proxies in paleoceanography. The classification of modern species is amply illustrated with electron and light microscope images of morphotypes, addresses the state-of-the-art of molecular genetics of species, and provides a detailed guide for any laboratory analyses. The biology of planktic foraminifers is extensively discussed in chapters dedicated to the cellular ultrastructure, nutrition, symbionts, reproduction, ontogeny, and test architecture. Building on the biological prerequisites, the distribution of planktic foraminifers is discussed at regional to global scale. The geochemistry and sedimentation of tests are considered in relation to the ecology of the living animal. In the final chapter, which examines the most common methods in planktic foraminifer research, hands-on information is provided on sampling, processing and analyzing samples in the laboratory, as well as selected established methods for data interpretation. The various topics discussed in this book are aimed at the application of planktic foraminifers as sensitive indicators of the changing climate and marine environment.

Download or read book Isoscapes written by Jason B. West and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stable isotope ratio variation in natural systems reflects the dynamics of Earth systems processes and imparts isotope labels to Earth materials. Carbon isotope ratios of atmospheric CO2 record exchange of carbon between the biosphere and the atmosphere; the incredible journeys of migrating monarchs is documented by hydrogen isotopes in their wings; and water carries an isotopic record of its source and history as it traverses the atmosphere and land surface. Through these and many other examples, improved understanding of spatio-temporal isotopic variation in Earth systems is leading to innovative new approaches to scientific problem-solving. This volume provides a comprehensive overview of the theory, methods, and applications that are enabling new disciplinary and cross-disciplinary advances through the study of "isoscapes": isotopic landscapes. "This impressive new volume shows scientists deciphering and using the natural isotope landscapes that subtly adorn our spaceship Earth.", Brian Fry, Coastal Ecology Institute, Louisiana State University, USA "An excellent timely must read and must-have reference book for anybody interested or engaged in applying stable isotope signatures to questions in e.g. Anthropology, Biogeochemistry, Ecology, or Forensic Science regarding chronological and spatial movement, changes, or distribution relating to animals, humans, plants, or water.", Wolfram Meier-Augenstein, Centre for Anatomy & Human Identification, University of Dundee, UK "Natural resources are being affected by global change, but exactly where, how, and at what pace? Isoscapes provide new and remarkably precise answers.", John Hayes, Woods Hole Oceanographic Institution, USA "This exciting volume is shaping a new landscape in environmental sciences that is utilizing the remarkable advances in isotope research to enhance and extend the capabilities of the field.", Dan Yakir, Weizmann Institute of Science, Israel

Download or read book The Biological Fractionation of Isotopes written by Eric Galimov and published by Elsevier. This book was released on 2012-12-02 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biological Fractionation of Isotopes focuses on the biological fractionation of isotopes and presents calculations of the thermodynamic isotopic beta factor for polyatomic carbon compounds. This book provides experimental and theoretical evidence of the phenomenon of thermodynamically ordered distribution of isotopes in biological systems. This book consists of 12 chapters and opens with an overview of the causes of fractionation of isotopes, along with concepts such as isotopic composition and isotopic effects. The discussion then turns to the isotopic composition of the carbon of organisms; a method of calculating the thermodynamic isotopic factors of polyatomic compounds; and results of experimental investigations of intermolecular and intramolecular isotopic effects. A theoretical model of biological fractionation of isotopes is also described. The following chapters explore the regularities of the biological distribution of isotopes and present the results of some biochemical experiments, including the enzymatic decarboxylation of pyruvate and microbiological oxidation of ethanol to acetic acid. In addition, the geologic aspects of thermodynamically ordered isotopic distributions in biological products are analyzed. This monograph will be of interest to biologists, geochemists, analytical chemists, and geologists.

Download or read book The Global Carbon Cycle and the Evolution of Photosynthesis written by Alexander A. Ivlev and published by Cambridge Scholars Publishing. This book was released on 2019-11-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with the problem of the interaction and interconditionality of the various processes occurring in both the Earth’s crust and the biosphere. It proposes a model of the global carbon cycle explaining the nature and mechanism of these interactions, showing that the key element of this interaction is the photosynthesis controlled by periodic carbon dioxide injections caused by collision zones of lithospheric plates. Changes in the environment due to the evolution of photosynthesis cause alterations in the carbon cycle, and lead to a stationary state when new features of the cycle are manifested. The main instruments of the analysis here are the isotopic technique and physico-chemical modeling, conducted on the basis of the principle of actualism. The model provides explanations of periodic mass extinctions of organisms, the “explosions of life”, the uneven distribution of organic matter in the sedimentary strata, stratigraphic oil distribution, and various other events in the biosphere in the course of geological history. The book will appeal to geologists, geochemists, climatologists, ecologists, biologists, and specialists in global change.
