Book excerpt: Isotope is Biology is a six-chapter supplementary text that covers the properties and application of isotopes as labels or analytical tools in biological research. The first chapters deal with the physico-chemical properties and radioactivity of isotopes. These chapters also explore their synthesis, preparation, radiation decomposition, and decay of radioactivity. The succeeding chapter considers other aspects of isotopes, including their effect of health, disposal, spills, and laboratory use. Another chapter examines the chemical and biochemical behavior, natural abundance, and the chemical stability of isotopic compounds. The final chapters describe several isotopic methods, namely, isotope dilution, paper chromatography, and autoradiography, with emphasis on their application in biological studies. This book will be of value to biologists, and graduate and undergraduate biology students.

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.

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 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 Isotopes for Medicine and the Life Sciences written by Institute of Medicine and published by National Academies Press. This book was released on 1995-01-27 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioactive isotopes and enriched stable isotopes are used widely in medicine, agriculture, industry, and science, where their application allows us to perform many tasks more accurately, more simply, less expensively, and more quickly than would otherwise be possible. Indeed, in many casesâ€"for example, biological tracersâ€"there is no alternative. In a stellar example of "technology transfer" that began before the term was popular, the Department of Energy (DOE) and its predecessors has supported the development and application of isotopes and their transfer to the private sector. The DOE is now at an important crossroads: Isotope production has suffered as support for DOE's laboratories has declined. In response to a DOE request, this book is an intensive examination of isotope production and availability, including the education and training of those who will be needed to sustain the flow of radioactive and stable materials from their sources to the laboratories and medical care facilities in which they are used. Chapters include an examination of enriched stable isotopes; reactor and accelerator-produced radionuclides; partnerships among industries, national laboratories, and universities; and national isotope policy.
Download or read book Carbon Isotope Techniques written by David C. Coleman and published by Academic Press. This book was released on 2012-12-02 with total page 287 pages. 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.
