Books in Agricultural and biological sciences

The Agricultural and Biological Sciences collection advances science-based knowledge for the improvement of animal and plant life and for secure food systems that produce nutritious, novel, sustainable foods with minimal environmental impact. Food Science titles include not only those products from agriculture but all other aspects from food production to nutrition, health and safety, chemistry to security, policy, law and regulation. Biological Sciences address animal behaviour and biodiversity, organismal and evolutionary biology, entomology, marine biology and aquaculture, plant science and forestry.

Here, for the first time, is a single source of ordered, coherent information about the handling and storage of grain, grain derivatives and substitutes. The author has had a lifetime's experience in this field and the book is the culmination of six years spent compiling the valuable technical information gained from his extensive know-how. The book surveys various techniques and practical engineering options for the study, design, construction, safety, operation and maintenance of grain handling and storage facilities. An extensive bibliography permits direct access to the primary literature and the text is supplemented throughout by numerous illustrations, line drawings and photographs.With its complete and comprehensive coverage and systematic layout, the book provides a wealth of information on the basic technology and the latest developments in this field. It will be welcomed by a wide readership, including general managers, plant and engineers, manufacturers, insurance companies and all technicians and professionals involved in the daily operation, maintenance and safety of such facilities.

The Genus Coelomomyces

The Genus Coelomomyces aims to elucidate the utilization of Coelomomyces spp. as agents for the biological control of mosquitoes. This book begins with the life history of species of Coelomomyces, followed by the species’ structure and development. It also expounds the taxonomy, experimental systematics, physiology, biochemistry, and culture of Coelomomyces. Lastly, it discusses the ecology and use of Coelomomyces species in biological control. This book will serve as a catalyst for new and expanded studies on Coelomomyces species.

Subviral Pathogens of Plants and Animals: Viroids and Prions

Subviral Pathogens of Plants and Animals: Viroids and Prions is organized into four parts consisting of a total of 20 chapters that discuss the nature of subviral pathogens of plants and animal. This book first elucidates the recognition of subviral pathogens, and then explores the host range of viroids and its diseases. It also addresses the control of viroid diseases. The book explains the structure and replication of viroids. Lastly, it centers on the structure and biology of prions, as well as the diseases these pathogens cause. This treatise will be of considerable scientific interest and importance to those in the field of human and veterinary medicine, virology, zoology, microbiology, plant pathology, entomology, as well as other branches of biology.

Evapotranspiration from Plant Communities

A change in land use has been found to alter the components of the hydrological cycle through its effects on evapotranspiration. This influences planning and management of water resources. The Workshop, from which this volume was derived, was organized in this context to discuss processes and techniques relevant to estimating evapotranspiration of communities ranging from agricultural to forested lands. Its objectives were to provide a forum for exchange of ideas, to gather up-to-date information on the state of the art, and to identify priority areas for future research.The eighteen papers in this volume have been selected from those presented at the Workshop on the basis of technical quality and subject matter coverage and result in a valuable contribution to our current understanding of evapotranspiration.

Before Water Management Measures

The ultimate motivation for the study which is the subject of this book was the need to draw conclusions on the impact of man's activity on natural ecosystems. The results characterize the situation of the south-Moravian floodplain forest in the period of fading uncontrolled floods before the extensive technical measures successively changed the moisture regime by eliminating inundation and lowering the level of underground water. This publication is unique in Czechoslovakia as it records the ecological situation in the floodplain forest prior to the major and irreversible changes. The study also documents the exceptional role played by the Central-European floodplain forest in maintaining the gene pool and structure of the one thousand or so species in flora and fauna of an agricultural region.

Ecosystem analysis and ecological modelling is a rapidly developing interdisciplinary branch of science used in theoretical developments in ecology and having practical applications in environmental protection. In this book, the authors introduce new holistic, particularly cybernetic, concepts into ecosystem theory and modelling, and provide a concise treatment of mathematical modelling of freshwater ecosystems which covers methods, subsystem models, applications and theoretical developments.Part I begins with a brief introduction to the principles of systems theory and their applications to ecosystems, and provides a summary of various methods of systems analysis. In Part II emphasis is laid on the pelagic processes in standing water, characterised by relatively uninvolved structures from which models can be readily developed. Part III describes applications of the technique of modelling to solutions of theoretical and practical problems, with different modelling methods and objectives being used in the various chapters. More recent developments in the methods and theory of ecosystem modelling are covered in Part IV which also includes a discussion of future trends. The book is addressed to practising ecologists and engineers in the fields of ecology, limnology, environmental protection, and water quality managements, as well as to graduate/post-graduate university students in science and engineering. Students and researchers involved in environmental applications of mathematics and cybernetics will also find the book of interest.
