Book Description
Although the basic evolutionary patterns of nitrogen metabolism and excretion have been outlined for decades, there has been a resurgence of research activity in the past 15 years. Research in nitrogen metabolism has been stimulated in the area of acid-base balance. The molecular revolution has had an impact on the field as well, and recent studies on nitrogen metabolism and excretion now almost routinely use the tools of molecular biology. Of special interest are recent studies of evolutionary relationships between proteins of nitrogen metabolism. Nitrogen Metabolism and Excretion updates the reader on progress being made in this subject, offering an exciting integration of traditional topics and discussions on the most recent issues which have not yet appeared in other textbooks or references. The book features chapters on the latest developments in nitrogen metabolism and excretion from 28 prominent researchers from all over the world. Each chapter is detailed and specific, filled with useful concepts and techniques. The scope of the book is broad and diverse, covering groups from invertebrates to mammals, and subjects from nitrogen in oceanic buoyancy regulation to molecular mechanisms of nitric oxide synthesis. The text provides a phylogenetic view of various animal groups and presents much new information intended to break down phylogenetic stereotypes. The general areas of development, maternal-fetal interactions, protein turnover, carbamoyl phosphate synthesis, nitric oxide, and nitrates and nitrites are also covered in depth. This volume is the first in a new series that brings about a modern synthesis of areas of animal physiology. Nitrogen Metabolism and Excretion benefits both established researchers interested in nitrogen and advanced undergraduate and graduate students who want to investigate the most current and exciting questions being studied and debated.

Book Description
This textbook provides a comprehensive overview on the diverse strategies invertebrate animals have developed for nitrogen excretion and maintenance of acid-base balance and summarizes the most recent findings in the field, obtained by state-of-the-art methodology. A broad range of terrestrial, freshwater and marine invertebrate groups are covered, including crustaceans, cephalopods, insects and worms. In addition the impact of current and future changes in ocean acidification on marine invertebrates due to anthropogenic CO2 release will be analyzed. The book addresses graduate students and young researchers interested in general animal physiology, comparative physiology and marine/aquatic animal physiology. Also it is an essential source for researchers dealing with the effects of increasing pCO2 levels on aquatic animals, of which the vast majority are indeed invertebrates. All chapters are peer-reviewed.

Book Description
This book results from a symposium on the theme of 'The Physiology and Biochemistry of Plant Productivity' which was held at the University of Calgary from July 14-18, 1980, and was jointly sponsored by the Canadian Society of Plant Physiologists and the International Association of Plant Physiologists. The subject matter of the book deals with various aspects of nitrogen and carbon metabolism, their interrelationships and interdependence. The topics covered in the chapters highlight various interesting and important lines of research that are in progress. There is no attempt to provide a comprehensive coverage of the basic physiological knowledge upon which this research depend- important references are to be found at the end of each chapter, however, and the reader will be able to pursue these as necessary. An introductory chapter by Dr. R.G.S. Bidwell (winner of the C.S.P.P. Gold Medal in 1979) considers some implications of plant physiological research and the aims and responsibilities of plant physiologists. In the next two chapters Drs. J. Rigaud and L.E. Schrader (with R.J. Thomas) elaborate on current research on nitrate metabolism and nitrogen fixation, and how an understanding of these phenomena might be usefully applied towards the manipulation of plants to improve productivity.

Book Description
It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Book Description
Nitrogen is arguably the most important nutrient required by plants. However, the availability of nitrogen is limited in many soils and although the earth's atmosphere consists of 78.1% nitrogen gas (N2) plants are unable to use this form of nitrogen. To compensate , modern agriculture has been highly reliant on industrial nitrogen fertilizers to achieve maximum crop productivity. However, a great deal of fossil fuel is required for the production and delivery of nitrogen fertilizer. Moreover carbon dioxide (CO2) which is released during fossil fuel combustion contributes to the greenhouse effect and run off of nitrate leads to eutrophication of the waterways. Biological nitrogen fixation is an alternative to nitrogen fertilizer. It is carried out by prokaryotes using an enzyme complex called nitrogenase and results in atmospheric N2 being reduced into a form of nitrogen diazotrophic organisms and plants are able to use (ammonia). It is this process and its major players which will be discussed in this book. Biological Nitrogen Fixation is a comprehensive two volume work bringing together both review and original research articles on key topics in nitrogen fixation. Chapters across both volumes emphasize molecular techniques and advanced biochemical analysis approaches applicable to various aspects of biological nitrogen fixation. Volume 1 explores the chemistry and biochemistry of nitrogenases, nif gene regulation, the taxonomy, evolution, and genomics of nitrogen fixing organisms, as well as their physiology and metabolism. Volume 2 covers the symbiotic interaction of nitrogen fixing organisms with their host plants, including nodulation and symbiotic nitrogen fixation, plant and microbial "omics", cyanobacteria, diazotrophs and non-legumes, field studies and inoculum preparation, as well as nitrogen fixation and cereals. Covering the full breadth of current nitrogen fixation research and expanding it towards future advances in the field, Biological Nitrogen Fixation will be a one-stop reference for microbial ecologists and environmental microbiologists as well as plant and agricultural researchers working on crop sustainability.

Book Description
This book focuses on the very latest developments in our understanding of how plants use light energy and fixed carbon to assimilate nitrate and ammonium into the organic compounds required for growth. From the partitioning of organic nitrogen within the photosynthetic apparatus, through the primary processes of reduction of nitrate and nitrite and the assimilation of ammonium and its cycling in photorespiration, the complex interactions inherent in the crosstalk between carbon and nitrogen assimilation are considered and exciting new developments such as nitric oxide production evaluated. Attention is paid throughout to the close coordination of photosynthetic and respiratory processes in nitrogen assimilation. Emerging concepts of the interdependence of chloroplasts and mitochondria are described, and essential communication, transport and signalling processes are highlighted.
