Download or read book Echolocation in Bats and Dolphins written by Jeanette A. Thomas and published by University of Chicago Press. This book was released on 2004 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research. Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.

Download or read book How nature shaped echolocation in animals written by Mariana L Melcón and published by Frontiers E-books. This book was released on 2014-11-24 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Echolocation has evolved in different groups of animals, from bats and cetaceans to birds and humans, and enables localization and tracking of objects in a dynamic environment, where light levels may be very low or absent. Nature has shaped echolocation, an active sense that engages audiomotor feedback systems, which operates in diverse environments and situations. Echolocation production and perception vary across species, and signals are often adapted to the environment and task. In the last several decades, researchers have been studying the echolocation behavior of animals, both in the air and underwater, using different methodologies and perspectives. The result of these studies has led to rich knowledge on sound production mechanisms, directionality of the sound beam, signal design, echo reception and perception. Active control over echolocation signal production and the mechanisms for echo processing ultimately provide animals with an echoic scene or image of their surroundings. Sonar signal features directly influence the information available for the echolocating animal to perceive images of its environment. In many echolocating animals, the information processed through echoes elicits a reaction in motor systems, including adjustments in subsequent echolocation signals. We are interested in understanding how echolocating animals deal with different environments (e.g. clutter, light levels), tasks, distance to targets or objects, different prey types or other food sources, presence of conspecifics or certain predators, ambient and anthropogenic noise. In recent years, some researchers have presented new data on the origins of echolocation, which can provide a hint of its evolution. Theoreticians have addressed several issues that bear on echolocation systems, such as frequency or time resolution, target localization and beam-forming mechanisms. In this Research Topic we compiled recent work that elucidates how echolocation – from sound production, through echolocation signals to perception- has been shaped by nature functioning in different environments and situations. We strongly encouraged comparative approaches that would deepen our understanding of the processes comprising this active sense.
Download or read book The Neural Basis of Echolocation in Bats written by George D. Pollak and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain of an echo locating bat is devoted, in large part, to analyzing sound and conducting behavior in a world of sounds and echoes. This monograph is about analysis of sound in the brainstem of echolocating bats and concerns the relationship between brain structure and brain function. Echolocating bats are unique subjects for the study of such relationships. Like man, echolocating bats emit sounds just for the purpose of listening to them. Simply by observing the bat's echolocation sounds, we know what the bat listens to in nature. We therefore have a good idea what the bat's auditory brain is designed to do. But this alone does not make the bat unique. The brain of the bat is, by mammalian standards, rather primitive. The unique aspect is the combination of primitive characteristics and complex auditory processing. Within this small brain the auditory structures are hypertrophied and have an elegance of organization not seen in other mammals. It is as if the auditory pathways had evolved while the rest of the brain remained evolutionary quiescent.
Download or read book Bat Bioacoustics written by M. Brock Fenton and published by Springer. This book was released on 2016-06-02 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arguably biosonar is one of the ‘eye-opening’ discoveries about animal behavior and the auditory systems of echolocators are front and center in this story. Echolocation by bats has proven to be a virtual gold mine for colleagues studying neurobiology, while providing many rich examples of its impact on other areas of bats’ lives. In this volume we briefly review the history of the topic (reminding readers of the 1995 Hearing by Bats). We use a chapter on new findings in the phylogeny of bats to put the information that follows in an evolutionary context. This includes an examination of the possible roles of Prestin and FoxP2 genes and various anatomical features affecting bat vocalizations. We introduce recent work on the role of noseleafs, ears, and other facial components on the focusing of sound and collection of echoes.
Download or read book Biosonar written by Annemarie Surlykke and published by Springer. This book was released on 2014-07-19 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.

Download or read book Neuroethology and Behavioral Physiology written by F. Huber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Physiology of Marine Mammals written by Michael Castellini and published by CRC Press. This book was released on 2023-07-05 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suppose you were designing a marine mammal. What would they need to live in the ocean? How would you keep them warm? What design features would allow them to dive for very long periods to extreme depths? Do they need water to drink? How would they minimize the cost of swimming, and how would they find their prey in the deep and dark? These questions and more are examined in detail throughout Marine Mammal Physiology, which explores how marine mammals live in the sea from a physiological point of view. This undergraduate textbook considers the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. It focuses on the physiological and biochemical traits that have allowed this group of mammals to effectively exploit the marine environment that is so hostile to humans. The content of this book is organised around common student questions, taking the undergraduate's point of view as the starting point. Each chapter provides a set of PowerPoint slides for instructors to use in teaching and students to use as study guides. New "Study Questions" and "Critical Thinking Points" conclude each chapter, which are each motivated by a "Driving Question" such as "How do mammals stay warm in a cold ocean?" or "How do mammals survive the crushing pressures of the deep sea?" Full-colour images and comprehensive, accessible content make this the definitive textbook for marine mammal physiology.

Download or read book Basic Mechanisms in Hearing written by Aage Moller and published by Elsevier. This book was released on 2012-12-02 with total page 956 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic Mechanisms in Hearing is a collection of papers that discusses the function of the auditory system covering its ultrastructure, physiology, and the mechanism's connection with experimental psychology. Papers review the mechanics, morphology, and physiology of the cochlear, including the physiology of individual hair cells and their synapses. One paper examines the combined physiological and anatomical studies of stimulus coding in the mammalian auditory nervous system. The results of these studies pertain to the latency, frequency selectivity, and time pattern of responses to short tone bursts. Other research compare the cochlear nerve, behavioral, and psychophysical frequency selectivity which show that frequency selectivity of the auditory system occurs at the level of the cochlear nerve, becoming downgraded in end-organ deafness. Other papers discuss neural coding at higher levels such as the feature extraction in the auditory system of bats. Some papers also analyze the specialized hearing mechanisms in animals, for example, the echolocation of bats and in some insects, the function of the swimbladder in fish hearing, as well as the "invertebrate frequency analyzer" in the locust ear. Physiologists, neurophysiologists, neurobiologists, general medical practioners, and EENT specialists will find this collection valuable.
Download or read book Hearing by Bats written by Richard R. Fay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Springer Handbook oj Auditory Research presents a series of com prehensive and synthetic reviews of the fundamental topics in modern auditory research. It is aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes will introduce new investigators to important aspects of hearing science and will help established investigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the literature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The series focuses on topics that have developed a solid data and conceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature. Each volume in the series consists of five to eight substantial chapters on a particular topic. In some cases, the topics will be ones of traditional interest for which there is a solid body of data and theory, such as auditory neuroanatomy (Vol. 1) and neurophysiology (Vol. 2). Other volumes in the series will deal with topics which have begun to mature more recently, such as development, plasticity, and computational models of neural processing.
