Chemical Ecology
Chemical signals among organisms form "a vast communicative interplay, fundamental to the fabric of life," in the words of one expert. Chemical ecology is the the discipline that seeks to understand these interactions-to use biology in the search for new substances of potential benefit to humankind. This book highlights selected research areas of medicinal and agricultural importance. Leading experts review the chemistry of: Insect defense and its applications to pest control. Phyletic dominanceâ€"the survival success of insects. Social regulation, with ant societies as a model of multicomponent signaling systems. Eavesdropping, alarm, and deceitâ€"the array of strategies used by insects to find and lure prey. Reproductionâ€"from the gamete attraction to courtship nd sexual selection. The chemistry of intracellular immunosuppression. Topics also include the appropriation of dietary factors for defense and communication; the use of chemical signals in the marine environment; the role of the olfactory system in chemical analysis; and the interaction of polydnaviruses, endoparasites, and the immune system of the host.
Model Neural Networks and Behavior
The most conspicuous function of the nervous system is to control animal behav ior. From the complex operations of learning and mentation to the molecular con figuration of ionic channels, the nervous system serves as the interface between an animal and its environment. To study and understand the fundamental mecha nisms underlying the control of behavior, it is often both necessary and desirable to employ biological systems with characteristics especially suitable for answering specific questions. In neurobiology, many invertebrates have become established as model systems for investigations at both the systems and the cellular level. Large, readily identifiable neurons have made invertebrates especially useful for cellular studies. The fact that these neurons occur in much smaller numbers than those in higher animals also makes them important for circuit analysis. Although important differences exist, some of the questions that would be tech nically impossible to answer with vertebrates can become experimentally tractable with invertebrates.
Neurobiology of Chemical Communication
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism-ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their prese
Neurotox ’91
NEUROTOX '91 was the fourth meeting in a series which started in 1979. The '91 meeting, like its predecessors, was held under the patronage of the Society of Chemical Industry, and despite the unfortunate proximity of hostilities in the Arabian Gulf attracted a truly international mix of industrial and academic pesticide scientists. This volume contains the text of invited papers read at the meeting and presents the dramatic developments which so excited those who attended. The potential of molecular neurobiology for gaining knowledge of target sites for neurotoxicants is now starting to be realised. These studies, in conjunction with developments in molecular imaging and modelling, provide ...
Neuronal Coding Of Perceptual Systems - Proceedings Of The International School Of Biophysics
This book provides a most complete overview of physiological and psychophysical properties of perceptual systems in man and animals. The information processing chains are described step-by-step from the stimuli of the respective environments, via the perceptual neuronal coding networks to conscious sensations and behaviour.Articles by W G K Backhaus, A G Clark, B Hiley, A Iznak, M Kavaliers, B Kramer, A Michelsen, C Neumeyer, G A Orban, T Radil, D G Stavenga, M Stengl, U Thurm, R L DeValois, R Wehner, J S Werner, W Wiltschko, and related short articles.
Insect Olfaction
JOHN G. HILDEBRAND Research on insect olfaction is important for at least two reasons. First, the olfactory systems of insects and their arthropod kin are experi mentally favourable models for studies aimed at learning about general principles of olfaction that apply to vertebrates and invertebrates alike. Detailed comparisons between the olfactory pathways in vertebrates and insects have revealed striking similarities of functional organisation, physiol ogy, and development, suggesting that olfactory information is processed through neural mechanisms more similar than different in these evolution arily remote creatures. Second, insect olfaction itself is important because of the economic an...
Pheromone Communication in Moths
Common among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Ê Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and cour...
Neurochemical Techniques in Insect Research
Neurochemical Techniques in Insect Research properly emphasizes the insect. It only scratches the surface of the exploding repertoire of general neuro chemical techniques that can be applied to insect research in 1985. But it al so presents the advantages of using insects for studying certain biological questions that are approachable by neurochemical techniques. Even more so, it summarizes the long list of unique problems encountered in attempting to study insects by neurochemical techniques. As in other volumes of this series, the contributors to this volume are the authorities in the field. They themselves have developed much of the material presented. Thus the sum effort provides a true ...
Proceedings of the 11th International Symposium on Insect-Plant Relationships
The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingør, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.
