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.

The first meeting on biosonar that I had the opportunity to attend was held in 1978 on the Island of Jersey in the English Channel. That meeting, organized by Professor R.G. Busne1 and Dr. Jim Fish, was my introduction to an exciting and varied group of hard-working and dedicated scientists studying animal echolocation. They are, by nature, a very diverse group. They tend to publish in different journals and rarely interact despite the fact that they all work on echolocation. When they do interact as a group, as they did in Frascati Italy in 1966, in Jersey i~ 1978, and during the meeting reported in this volume, the meetings are intense, interesting, and exciting. This volume is a composition of a series of contributed papers written to foster an interdisciplinary understanding of the echolocation systems of animals. The echolocation pulse production studies in bats and dolphins have recently been concentrated on the ontogeny of infant pulses, other studies, with three-dimensional computer graphics and x-ray computed tomography, have concentrated on finally resolving the old controversy concerning the site of dolphin echolocation click production. Much has been accomplished on the analysis of bat neural structure and function. The intense effort directed toward understanding the structure, connections, and functional properties of parallel auditory pathways and the parallel and hierarchical processing of information by the mustached bat, has lead to dramatic breakthroughs in understanding brain function.

How are dolphins and bats alike? They can both see with their ears! That is, they both use sound to navigate and find food. Designed for grades K-5 and to be done at home or with small groups, this interactive multi-activity mini-course introduces children to the amazing process of echolocation and how dolphins and bats manage to accomplish it. The mini-course includes a richly illustrated story-based lesson as well as games, activities, and projects that appeal to all types of learners. How can dolphins and bats accomplish such a cool feat? After reading the fun, illustrated story about Dolphin and Bat School, children reinforce the features that make echolocation possible through an echolocation elements board game (included in the course). They then get to experience echolocation through a movement-based Name That Sound game in which children must themselves try to echolocate. Finally, children can cement their knowledge of the anatomical features involved in echolocation through an art project in which they create their own bat ears or dolphin snout. Most materials needed to complete the mini-course can be cut from the book itself (or, if preferred, downloaded and printed using an included link). The mini-course requires only a few common household items to complete the activities: blindfold (scarf or headband), blank paper, blanket, pen or pencil, coloring materials (crayons, markers or colored pencils), tape, and scissors. Upon completing the mini-course, children will be provided with links to additional online resources and will earn new concept badges for their Science Tool Kit (included in the mini-course)-including echolocation, larynx, noseleaf, phonic lips, melon, and blowhole.

The extraordinary ability of dolphins to echolocate has fascinated scientists and the public since its discovery in the late 1950's. This is the first book to summarize modern research in this area, and presents a broad synthesis of this very interdisciplinary subject. The author is an internationally-recognized expert on dolphin sonar and is thus in a unique position to bring together research on the physiological, mathematical and engineering aspects of the subject. Of interest to auditory researchers, electrical engineers, acoustical physicists, and mammalian physiologists.

Because of the ease with which we perceive, many people see perception as something that "just happens." However, even seemingly simple perceptual experiences involve complex underlying mechanisms, which are often hidden from our conscious experience. These mechanisms are being investigated by researchers and theorists in fields such as psychology, cognitive science, neuroscience, computer science, and philosophy. A few examples of the questions posed by these investigations are, What do infants perceive? How does perception develop? What do perceptual disorders reveal about normal functioning? How can information from one sense, such as hearing, be affected by information from another sense, such as vision? How is the information from all of our senses combined to result in our perception of a coherent environment? What are some practical outcomes of basic research in perception? These are just a few of the questions this encyclopedia will consider, as it presents a comprehensive overview of the field of perception for students, researchers, and professionals in psychology, the cognitive sciences, neuroscience, and related medical disciplines such as neurology and ophthalmology.

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.

BIOLOGY, Seventh Edition by Solomon, Berg, and Martin continues to be the best-liked and most student-friendly introductory majors text available. In this edition the authors have created a learning system that makes the chapters easier to navigate and provides a variety of ways for students to learn the material. Learning Objectives are now strategically placed throughout the chapter following major headings, and there are review questions at the ends of these major sections. Chapter Summaries are now organized around the Learning Objectives as well, making it easier for students to return to the place in the book that can help them work through the end-of-chapter material. Icons throughout the chapter direct students to the BiologyNow CD and tells them what they will find there. BiologyNow, the new Student CD-ROM for BIOLOGY Seventh Edition, is also based on these Learning Objectives to further reinforce the text's concepts. The BiologyNow CD, fully integrated with the Seventh Edition text, provides access to diagnostic pre-tests for each chapter. It also automatically generates customized learning plans for students, directing students to the information in the book, ancillaries and media program that will help them master specific concepts. Post-tests allow students to assess their progress as well. Personal Tutor with SMARTHINKING, a FREE online live tutoring service. Students can ask questions, get answers, and they don't need to set up appointments! For instructors, a Multimedia Manager provides the text art in PowerPoint form. Instructors also receive an Instructor's Guide, ExamView Electronic Testing and WebTutor course management options. Solomon, Berg, and Martin have gone beyond presenting facts for memorization -- they have created a well-designed pedagogical system through their use and reuse of chapter Learning Objectives, which is supported by an unbelievable package of materials for instructors and students. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.
