Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

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 2001-07-31 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a very strong practical orientation, telling readers what methodologies are available using stable isotopes, how studies should be designed and executed to maximise effectiveness and incisiveness in terms of data obtained and outcomes in terms of understanding events and processes in plant and ecosystem functioning. The readership is very much aimed toward postgraduates with good knowledge of general biological principles and underlying chemical and physical processes. Pre-existing knowledge of or experience in application and assay of stable isotopes is not required. The stable isotope research field is one of the most rapidly growing areas of ecophysiology and techniques using stable isotopes comprise an ever increasing component of research programs of university postgraduates and a wide range of agencies conducting environmental monitoring and rehabilitation programs. The book is tailor-made for such an audience.
