This volume explains the key ideas, questions and methods involved in studying the hidden world of vibrational communication in animals. The authors dispel the notion that this form of communication is difficult to study and show how vibrational signaling is a key to social interactions in species that live in contact with a substrate, whether it be a grassy lawn, a rippling stream or a tropical forest canopy. This ancient and widespread form of social exchange is also remarkably understudied. A frontier in animal behavior, it offers unparalleled opportunities for discovery and for addressing general questions in communication and social evolution. In addition to reviews of advances made in the study of several animal taxa, this volume also explores topics such as vibrational communication networks, the interaction of acoustic and vibrational communication, the history of the field, the evolution of signal production and reception and establishing a common vocabulary.

In creatures as different as crickets and scorpions, mole rats and elephants, there exists an overlooked channel of communication: signals transmitted as vibrations through a solid substrate. Peggy Hill summarizes a generation of groundbreaking work by scientists around the world on this long understudied form of animal communication. Beginning in the 1970s, Hill explains, powerful computers and listening devices allowed scientists to record and interpret vibrational signals. Whether the medium is the sunbaked savannah or the stem of a plant, vibrations can be passed along from an animal to a potential mate, or intercepted by a predator on the prowl. Vibration appears to be an ancient means of communication, widespread in both invertebrate and vertebrate taxa. Hill synthesizes in this book a flowering of research, field studies documenting vibrational signals in the wild, and the laboratory experiments that answered such questions as what adaptations allowed animals to send and receive signals, how they use signals in different contexts, and how vibration as a channel might have evolved. Vibrational Communication in Animals promises to become a foundational text for the next generation of researchers putting an ear to the ground.

This volume is a self-contained companion piece to Studying Vibrational Communication, published in 2014 within the same series. The field has expanded considerably since then, and has even acquired a name of its own: biotremology. In this context, the book reports on new concepts in this fascinating discipline, and features chapters on state-of-the art methods for studying behavior tied to substrate-borne vibrations, as well as an entire section on applied biotremology. Also included are a historical contribution by pioneers in the field and several chapters reviewing the advances that have been made regarding specific animal taxa. Other new topics covered are vibrational communication in vertebrates, multimodal communication, and biotremology in the classroom, as well as in art and music. Given its scope, the book will appeal to all those interested in communication and vibrational behavior, but also to those seeking to learn about an ancient mode of communication.

The investigation of the relationships between a behavior pattern and its underlying sensory and neurophysiological mechanisms in both man and animals dates back well into the last century. However, the concepts and findings of ethology and experimental psychology, together with an improved understanding of how the nervous system is organized and how neurons interact with each other, have only in the last 30 years laid the groundwork for an in-depth analysis. The many technological advances achieved in neurophysiology and neuroanatomy have also played an important role in this. The study of the neuronal bases of behavior - for which the term "neuroethology" has been coined - has thus become one of the central themes of neuroscience. Kenneth David Roeder, who died in 1979, was one of the pioneers of this field of research. It is to him that the contributions in this book are dedicated. K.D. Roeder was among the first to attempt to define the correlation between the natural behavior of an experimental animal and the activity of single sensory and nerve cells. The ques tions he asked, his experimental approach, and his fundamental discoveries are pre sented in an introductory chapter.

While we may have always assumed that insects employ auditory communication, our understanding of it has been impeded by various technical challenges. In comparison to the study of an insect's visual and olfactory expression, research in the area of acoustic communication has lagged behind. Filling this void, Insect Sounds and Communication is the

Every life form is made up of vibrations that coincide with the harmonic frequency to which all life is attuned. The vibrations of the body easily go out of tune when a person is exposed to physical or emotional stress. Vibrational Healing Through the Chakras provides the most up-to-date information on the use of vibrational tools such as crystals, aromas, sounds, bodywork, and homeopathy to help the body remember its own healthy harmonic resonance. Author Joy Gardner offers this in-depth look at vibrational healing for people interested in improving their own health and well-being, as well as those who want to become practitioners of this gentle art. Explore how to use vibrations to release old dysfunctional patterns in the body-mind and replace them with new patterns that resonate with the body's own healthy frequencies. • An in-depth resource guide to using vibrational tools at the chakra points to heal the body and mind. • Includes a detailed explanation of chakras and the human energy field and how to heal with a variety of tools including colors, crystals, aromatherapy, and light.

The present volume deals with the most fascinating aspects of sensory performance studied in insects, crustaceans and spiders. Arthropods inhabit practically every conceivable ecological niche, and are perfectly adapted to cope with the constraints of their natural habitats. They move on the ground, in water, and in the air. They use visual, olfactory, acoustical, vibratory, and tactile cues for orientation, to recognize and pinpoint their target, their home place, a feeding site, a prey, or a potential mate. Many arthropods use celestial (skylight) and terrestrial (magnetic) compass cues for orientation, and some of them were shown to develop, through experience, oriented behaviours based on a variety of innate, hard-wired orientation mechanisms. In many cases, aspects of behaviour that are involved in orientation cannot be separated from inter- and intraspecific communication. The book brings to the fore the role of communication not only in social and sexual behaviours, but also in the context of oriented locomotion. Top, internationally renowned scientists have contributed to this volume and have succeeded in presenting a book full of highlights which will be of great interest to workers in this field of research.

In recent years there has been a rapid increase in the understanding of communication between animals and this is perhaps especially true of bio-acoustics. In the last 35 years a completely new branch of bio acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the novelty of 'listening in' to these previously unknown sig nals, perhaps because of the wide variety of ways in which different animals use them. Many studies of different aspects of animal ultrasound have now been published and a review of them all seems to be timely. Ultrasound is is biologically arbitrary; other animals defined in human terms and may produce similar signals at lower frequencies for similar purposes. This book attempts to be comprehensive but the limits of the subject are rather difficult to define. It should be read in conjunction with other books on audible bio-acoustics. Each chapter has been written and may be read as a separate entity, although there is considerable cross-referencing. Chapters 1 and 2 form a common introduction and may help in understanding the later sections. The Appendix is not essential but is included for those who may be interested in the quanti tative aspects of the echo-location phenomena described in Chapters 3 and 8.
