Download or read book Variable plants and herbivores in natural and managed systems written by Robert Denno and published by Elsevier. This book was released on 2012-12-02 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variable Plants and Herbivores in Natural and Managed Systems examines individual, population, species, and community responses of herbivores to plant variation, with emphasis on insects, fungi, bacteria, and viruses. It is divided into five parts encompassing 18 chapters that discuss variability as a mechanism of defense used by plants against their parasites and the effects of variability on herbivores at several different levels of complexity. After a brief discussion on plant-herbivore interactions, the first part of this book considers sources of within-plant variation and effects on the distribution and abundance of herbivores. Part II examines interplant variation, the co-evolutionary problems it poses for herbivores, and the ecological and evolutionary responses of these animals. It discusses the effects of host-plant variability on the fitness of sedentary herbivorous insects. Part III discusses the role of host variability in the evolution of feeding specialization, genetic differentiation, and race formation. The importance of host variation to the organization of herbivore communities and the manipulation of host-plant variability for the management of herbivore pest populations are presented in the remaining parts. This book will be helpful to agriculturists, silviculturists, biologists, and researchers who wish to expand their knowledge in dynamics of plant-herbivore relationships.

Download or read book Mycotoxins and Animal Foods written by DUPLICATE Smith and published by CRC Press. This book was released on 1991-07-23 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ingestion of feed containing mycotoxins has serious adverse effects on the health of farm animals, contributing to reduced weight gain, lower reproductivity, damage to the immune system, severe illnesses, and even death. Mycotoxins formed in animal feedstuffs depend on the presence of specific strains of filamentous fungi or molds and are strongly influenced by environmental factors such as temperature and humidity. This book considers the biological nature of mycotoxin formation, the chemical and biological methods of analysis, as well as the extensive range of substrates capable of supporting the growth of toxigenic fungi. The book also provides extensive coverage of the mycotoxicoses of farmed animals and the current state of research into the control and detoxification of mycotoxins. All researchers interested in mycotoxins and their effects on animals will find important information in this book.
Download or read book Urea as a Protein Supplement written by Michael H. Briggs and published by Elsevier. This book was released on 2014-05-16 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urea as a Protein Supplement presents the significant advances that have been made in ruminant nutrition. This book examines the role of the rumen flora and fauna as synthesizers of protein from non-protein nitrogen sources such as ammonium compounds and urea. Organized into four parts encompassing 23 chapters, this book starts with an overview of the use of urea and other non-protein nitrogen sources in ruminant nutrition. This text then explores the various methods that may be used for the preparation of urea, which involves the dehydration of ammonium carbamate produced by the reaction of carbon dioxide and ammonia at high pressure and temperature. Other chapters consider the ways in which urea could be utilized to increase protein supplies. The final chapter deals with the hydrolysis of urea by urease to ammonia and carbon dioxide, which has been used as a method for determining urea for many years. Agricultural scientists and farmers will find this book useful.
