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 Stable Isotopes in Ecology and Environmental Science written by Robert Michener and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly. The second edition of this book provides a thorough, up-to-date examination of these methods of research. As part of the Ecological Methods and Concepts series which provides the latest information on experimental techniques in ecology, this book looks at a wide range of techniques that use natural abundance isotopes to: follow whole ecosystem element cycling understand processes of soil organic matter formation follow the movement of water in whole watersheds understand the effects of pollution in both terrestrial and aquatic environments study extreme systems such as hydrothermal vents follow migrating organisms In each case, the book explains the background to the methodology, looks at the underlying principles and assumptions, and outlines the potential limitations and pitfalls. Stable Isotopes in Ecology and Environmental Science is an ideal resource for both ecologists who are new to isotopic analysis, and more experienced isotope ecologists interested in innovative techniques and pioneering new uses.
Download or read book Geochemistry of Non Traditional Stable Isotopes written by Clark M. Johnson and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal for Volume 55 of Reviews in Mineralogy and Geochemistry was to bring together a summary of the isotope geochemistry of non-traditional stable isotope systems as is known through 2003 for those elements that have been studied in some detail, and which have a variety of geochemical properties. In addition, recognizing that many of these elements are of interest to workers who are outside the traditional stable isotope fields, we felt it was important to include discussions on the broad isotopic variations that occur in the solar system, theoretical approaches to calculating isotopic fractionations, and the variety of analytical methods that are in use. We hope, therefore, that this volume proves to be useful to not only the isotope specialist, but to others who are interested in the contributions that these non-traditional stable isotopes may make toward understanding geochemical and biological cycles. The review chapters in this volume were the basis for a two-day short course on nontraditional stable isotopes held prior (May 15-16, 2004) to the spring AGU/CGU Meeting in Montreal, Canada.

Download or read book Stable Isotope Techniques in the Study of Biological Processes and Functioning of Ecosystems written by M.J. Unkovich and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades technological advances in isotope ratio mass spectrometry have been very rapid, opening up new possibilities for analysis of biological and environmental materials. The new instrumentation has facilitated faster analysis of samples via automated sample preparation and multi-isotope analysis of single samples, resulting in considerable cost savings, and enabling access to isotope analysis for many more researchers. These changes are reflected in the rapidly growing international literature on stable isotopes. While there have been some excellent books and review papers aimed at interpreting isotope signals in biology and environmental science, there have been fewer attempts to provide practical tools for researchers making forays into this exciting new arena. This book aims to address this inadequacy by providing a set of practical guidelines for the application of a range of novel and well proven stable isotope techniques to the fields of plant physiological ecology, agriculture, marine ecology and palaeoecology. The book is the outcome of a weeklong workshop held under the auspices of the Cooperative Research Centre for Legumes in Mediterranean Agriculture (CLIMA 1992 - 2000) at The University of Western Australia and the CSIRO Floreat Laboratories, Perth, Western Australia, in February 1999. The workshop was designed to provide practical tools and experiences for researchers and students concerned with how one goes about using stable isotopes in field investigations.
