The Soil-Plant System in Relation to Inorganic Nutrition focuses on the soil-plant system in relation to the inorganic nutrition of plants. More specifically, the book investigates the dynamics of ion uptake in relation to those physical and chemical processes that must be considered both in understanding any observation made on the soil-plant system and in predicting the results of any stress placed on the system. This volume is organized into two parts encompassing seven chapters and begins with an overview of the inorganic nutrition of plants grown in the soil-plant system. This book then discusses the uptake of nutrient ions from the soil into the plant system. The emphasis is on fundamental aspects of ion movement from the soil into and through the soil solution, then into the plant root, and finally into the shoot. The next chapters consider the more practical aspects of the supply of nutrients to plants grown in the soil-plant system and how it can best be supplemented. This book examines the use of isotopes with respect to solid-phase-soil-solution relationships; movement of ions to the roots, into the roots (active or passive), and translocation to the shoot; the mobility of nutrients; laboratory, greenhouse, and field evaluation of soil nutrient supply; and when, where, and what kind of fertilizer to apply. This book will be of interest to botanists, biologists, students, and research workers engaged in the physical and biological sciences.

The Voluntary Food Intake of Farm Animals offers a wide discussion on food intake among farm animals. The book presents various studies, facts, details, and theories that are relevant to the subject. The first chapter begins by explaining the basic definition and significance of voluntary food intake. This topic is followed by discussions on meal patterns, the main features of eating, and the similarities between species. The next chapter explores theories about the food intake control, which are divided into two types: single-factor theories and multiple-factor theories. In Chapter 3, the discussion is on the foods pathway, including elaborations on the various receptors. Chapter 4 considers the central nervous systems involvement in the voluntary food intake and the energy balance regulation. The next couple of chapters highlight the possible reasons that affect food intake; among them are pregnancy, fattening, physical growths, and the environment. In the books remaining chapters, the discussion revolves around grass intake and the prediction and manipulation of voluntary food intake. The book serves as a valuable reference for undergraduates and postgraduates of biology and its related fields.

The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements ... The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge. Recent results of research were accommodated by devoting new chapters to the subjects "Methodology of Trace Element Research" and "Quality Assurance for Trace Element Analysis" and by expanding the discussion of lithium and aluminum in separate, new chapters. The first two subjects are of outstanding importance as determinants of future progress. The concern for the quality of analytical data motivated the authors of the individual chapters to review critically and, where necessary, revise analytical data presented in the previous editions. The rapid progress of trace analytical methodology since the mid-1970s has changed what had been accepted as normal for the concentrations of many trace elements in tissues and foods. The new data reflect the present state of the art in trace element analysis, but they may be subject to future revision.

Trace Elements in SoilPlantAnimal Systems discusses the adverse effects or the essentiality of trace elements in soil, plants, and animals under field and laboratory conditions. The book explores the chemistry, biochemistry, and physics of the availability of trace elements to several organisms, as well as their functions in cell metabolism. Organized into six parts encompassing 24 chapters, the book starts with an overview of the chain of events whereby trace elements are released from different soil and rock sources. The trace elements are then taken up by living organisms, transferred to their sites of action, and function in different metabolic events. The text explores how the trace elements occur in various chemical compounds with varying solubilities. Other chapters explore the principles governing the distribution of elements in minerals and igneous rocks. The final chapter deals with trace element disorders in living organisms. The book is a valuable resource to physicists, chemists, biochemists, geochemists, mineralogists, agriculturists, pedologists, scientists, researchers, and students.

"A transgenic animal is one that is genetically modified to carry genes from another species. Transgenic species can be raised to carry potentially useful genes from a variety of species. While the topics of genetic engineering and cloning are controversial, the reality is that these technologies offer tremendous benefits to society - from offering a framework for developing and screening medical therapies, to enhancing the safety and nutrition of the food we eat. One potential application of research into transgenic animal technology is the creation of domestic animals genetically designed to express a certain human disease and therefore serve as models for the study and treatment of human illnesses. Although many mouse models of human diseases are available today, such models in large domestic animals physiologically more similar to humans are sparse and critically needed. Further research in this field will undoubtedly uncover many more direct and indirect benefits of this technology. Transgenic animal technologies and the ability to introduce functional genes into animals have revolutionized our ability to address complex biomedical and biological questions. This well-illustrated handbook covers the technical aspects of gene transfer from molecular methods to whole animal considerations for important laboratory and domestic animal species. It describes methodologies as employed by leading laboratories and is a key resource for researchers, as well as a tool for training technicians and students.
