      Interaction of the Chemical Senses with Nutrition provides an understanding of the relationship of smell and taste to nutrition. This book discusses how the flavor of food can have substantial physiological effects influencing ingestion, digestion, and metabolism. Organized into five parts encompassing 21 chapters, this book starts with an overview of the significant role of saliva, which is involved in diet–taste relationships through dietary effects on saliva and salivary effects on taste perception. This text then reviews the literature on early salt acceptance in humans, contrasting and comparing those findings with data on the development of sweet preference. Other chapters consider the gustatory and anticipatory cephalic stimuli detected during a meal, which yield nutritional information and help in the efficient digestion of food. The final chapter deals with the transition stage in nutritional research. This book is a valuable resource for nutritionists, psychophysicists, scientists, public health professionals, and researchers.

      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.

      Physiological Mechanisms of Marine Pollutant Toxicity contains the proceedings of a symposium on ""Pollution and Marine Organisms"" held at the University of South Carolina in Columbia, South Carolina, on November 30 to December 3, 1981. It explores the effects of pollutants, such as petroleum hydrocarbons, heavy metals, and pesticides, on the physiology of marine organisms, along with the functional aspects of detoxification and the environmental health implications of pollution. Organized into three sections encompassing 24 chapters, this volume begins with a discussion of subcellular accumulation and detoxification of metals in aquatic animals such as fishes, crabs, and polychaetes. The reader is then introduced to the physiological mechanisms of pollutant toxicity, including the sublethal effects of pollutants on the gill morphology of the scallop, Placopecten magellanicus; mechanisms underlying the tolerance of killifish embryos to heavy metals; increased sensitivity of smolts in seawater to petroleum hydrocarbons, such as toluene and naphthalene; and physiological effects of sublethal concentrations of benzene and dimethylnaphthalene on blue crab juveniles. The book concludes by outlining research directions for linking cause and effect concerning pollution and marine organisms. This book will be a valuable resource for marine scientists, ecologists, and students.

      The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

      Insect trapping is a basic field research tool for many biologists, whether they are studying insect pests, disease vectors or insect ecology for its own sake. Any field entomologist contemplating a new insect trapping program or looking to improve or develop an existing scheme will benefit from this broad review of flying insect traps, in which the author draws on a wide variety of methods used by different research projects from all over the world. Over the years a great many traps have been developed and endlessly modified to suit particular species, habitats, and research requirements. In virtually every case the design of the trap interacts with the specific behavior of the insects involved to bias trap efficiency. In addition, the limited dialogue between workers in different subject disciplines and habitats has caused a shortage of new information available to field entomologists as a whole.

      Molecular Mechanisms in Cellular Growth and Differentiation describes the cellular differentiation and development. It emphasizes the pattern formation, specifically the genesis of spatial relationships, among the parts of a vertebrate or invertebrate organism, embryonic or adult. Organized into five parts, this book deals with the major steps leading from growth factor-receptor interactions, through transduction and modulation mechanisms, to proliferative response. It also discusses the relation of growth factors and their receptors to oncogenes and to protooncogenes. It also elucidates the roles of growth factors and receptors in cell differentiation and development, particularly, in pattern formation. The homeotic systems regulated intracellularly and the two differentiation systems thought to involve sequence-specific DNA-binding proteins in conjunction with small molecules are also explored.
