We are entering one of the most exciting periods in the study of chemical communication since the first pheromones were identified some 40 years ago. This rapid progress is reflected in this book, the first to cover the whole animal kingdom at this level for 25 years. The importance of chemical communication is illustrated with examples from a diverse range of animals including humans, marine copepods, Drosophila, Caenorhabditis elegans, moths, snakes, goldfish, elephants and mice. It is designed to be advanced, but at the same time accessible to readers whatever their scientific background. For students of ecology, evolution and behaviour, this book gives an introduction to the rapid progress in our understanding of olfaction at the molecular and neurological level. In addition, it offers chemists, molecular and neurobiologists an insight into the ecological, evolutionary and behavioural context of olfactory communication.
This book explains how animals use chemical communication, emphasising the evolutionary context and covering fields from ecology to neuroscience and chemistry.
Comprehensive Overview of Advances in OlfactionThe common belief is that human smell perception is much reduced compared with other mammals, so that whatever abilities are uncovered and investigated in animal research would have little significance for humans. However, new evidence from a variety of sources indicates this traditional view is likely
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 presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.
Animal Communication by Pheromones describes how the behavior of animals is controlled and influenced by pheromone communication. This book describes the mechanism through which the social animals interact with each other and by which they are organized according to their relative statuses and functions. The text then describes the pheromonal communication system; the mechanisms of movement and orientation to pheromone sources; and recognition, aggregation, and dispersion pheromone behaviors. The sex pheromone behavior; the environmental and physiological control of sex pheromone behavior; and the aspects of pheromones as stimulators or inhibitors of aggression are considered. The book further tackles sex pheromones; reproductive isolation; and the evolution of pheromonal communication. Entomologists and animal scientists will find the book useful.
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. 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 courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.
A wounded minnow attempts to rejoin its school and the other minnows scatter in panic; a single beetle finds a pine tree to its liking and soon thousands of beetles swarm that tree and others in the vicinity; a male Syrian golden hamster is drawn along an invisible trail to a burrow where a female hamster awaits him, ready for mating. These animals are responding to received communications, but, as in countless other occurrences in nature, the language is not auditory or visual--it is chemical. Unlike humans, who gather information largely through sight and sound, most living creatures rely heavily on chemical compounds from other organisms for their basic knowledge of the world. Among the various types of these compounds are the chemical signals exchanged between members of the same species that govern social interactions crucial to survival. These signals are called pheromones (from the Greek "pherein"--to carry--and "hormon"--exciting) and they are used to send warnings, establish territorial boundaries, provoke aggression, control sexual behavior, and locate food. In this volume, organic chemist William C. Agosta explores the chemistry of pheromones and the mechanisms by which they orchestrate animal behavior. Professor Agosta details the intricate process of identifying pheromones: first establishing that some behavior in animals is chemically driven, then isolating pheromones and determining the active components within these sometimes highly complex mixtures. He also demonstrates the value of this growing body of knowledge to our understanding of evolution, ecology, human behavior, and agricultural production. The result is a fascinating look at a research area that bringstogether investigators, information, technologies, and procedures from the fields of biology, chemistry, and behavioral science. Chemical Communication spans the entire spectrum of life, from simple organisms, such as water molds and brown algae, to insects, birds, fish, reptiles, mammals, and in a provocative final chapter, human beings. Along the way, Dr. Agosta provides dozens of captivating examples of pheromones in action: certain male red-sided garter snakes, which increase their chances of mating successfully by "impersonating" a female, thus distracting rivals; or the bolas spiders, which capture male moths by hitting them with an adhesive ball on a string after emitting a female moth pheromone that lures the males within range. The book also includes important evidence that pheromones alter physiology as well as behavior. For example, young female mice reach maturity at an accelerated pace after constant exposure to adult male mice.
This book explores the strikingly similar ways in which information is encoded in nonverbal man-made signals (e.g., traffic lights and tornado sirens) and animal-evolved signals (e.g., color patterns and vocalizations). The book also considers some coding principles for reducing certain unwanted redundancies and explains how desirable redundancies enhance communication reliability. Jack Hailman believes this work pioneers several aspects of analyzing human and animal communication. The book is the first to survey man-made signals as a class. It is also the first to compare such human-devised systems with signaling in animals by showing the highly similar ways in which the two encode information. A third innovation is generalizing principles of quantitative information theory to apply to a broad range of signaling systems. Finally, another first is distinguishing among types of redundancy and their separation into unwanted and desirable categories. This remarkably novel book will be of interest to a wide readership. Appealing not only to specialists in semiotics, animal behavior, psychology, and allied fields but also to general readers, it serves as an introduction to animal signaling and to an important class of human communication.
The crustaceans are ecologically and economically important organisms. They constitute one of the dominant invertebrate groups on earth, particularly within the aquatic realm. Crustaceans include some of the preferred scientific model organism, profitable aquaculture specimen, but also invasive nuisance species threatening native animal communities throughout the world. Chemoreception is the most important sensory modality of crustaceans, acquiring important information about their environment and picking up the chemical signals that mediate communication with conspecifics. Significant advances have been made in our understanding of crustacean chemical communication during the past decade. This includes knowledge about the identity, production, transfer, reception and behavioral function of chemical signals in selected crustacean groups. While it is well known that chemical communication is an integral part of the behavioral ecology of most living organisms, the intricate ways in which organisms allocate chemicals in communication remains enigmatic. How does the environment influence the evolution of chemical communication? What are the environmental cues that induce production or release of chemicals? How do individuals economize production and utilization of chemicals? What is the importance of molecule specificity or mix of a molecule cocktail in chemical communication? What is the role of chemical cues in multimodal communication? How does the ontogenetic stage, the sex or the physiological status of an individual affect its reaction to chemical cues? Many of these questions still represent important challenges to biologists.
Stress and Pheromonatherapy in Small Animal Clinical Behaviour is about how stress impacts on animal behaviour and welfare and what we can do about it, especially by using chemical signals more effectively. This readily accessible text starts from first principles and is useful to both academics and practitioners alike. It offers a framework for understanding how pheromonatherapy can be used to encourage desirable behaviour in dogs and cats and also a fresh approach to understanding the nature of clinical animal behaviour problems. The authors have pioneered the use of pheromone therapy within the field of clinical animal behaviour. As the culmination of many years of research and experience, they offer sound evidence-based advice on how and when pheromones can be used most effectively. The first part of the book deals with some fundamental concepts, focusing on the key concepts of stress, communication and perception. It then provides a framework for the evaluation of problem behaviour to allow consideration of the possible role or not of pheromonatherapy. Part 2 covers the application of these concepts to a range of specific situations, concentrating on conditions in which there has been most research to support the efficacy of pheromonatherapy. Suitable for veterinarians in small animal practice, students of clinical animal behaviour, veterinary nurses and technicians, as well as specialists and researchers in animal behaviour therapy.
