How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.

Animals have evolved remarkable biomechanical and physiological systems that enable their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of animal movement through a broad comparative and integrative approach, including basic mathematics and physics, examination of new and enduring literature, consideration of classic and cutting-edge methods, and a strong emphasis on the core concepts that consistently ground the dizzying array of animal movements. Across scales and environments, this book integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion. This second edition has been thoroughly revised, incorporating new content on non-vertebrate animal locomotor systems, studies of animal locomotion that have inspired robotic designs, and a new chapter on the use of evolutionary approaches to locomotor mechanisms and performance.

Animal Locomotion: Physical Principles and Adaptations is a professional-level, state of the art review and reference summarizing the current understanding of macroscopic metazoan animal movement. The comparative biophysics, biomechanics and bioengineering of swimming, flying and terrestrial locomotion are placed in contemporary frameworks of biodiversity, evolutionary process, and modern research methods, including mathematical analysis. The intended primary audience is advanced-level students and researchers primarily interested in and trained in mathematics, physical sciences and engineering. Although not encyclopedic in its coverage, anyone interested in organismal biology, functional morphology, organ systems and ecological physiology, physiological ecology, molecular biology, molecular genetics and systems biology should find this book useful.

The physical principles of swimming and flying in animals are intriguingly different from those of ships and airplanes. The study of animal locomotion therefore holds a special place not only at the frontiers of pure fluid dynamics research, but also in the applied field of biomimetics, which aims to emulate salient aspects of the performance and function of living organisms. For example, fluid dynamic loads are so significant for swimming fish that they are expected to have developed efficient flow control procedures through the evolutionary process of adaptation by natural selection, which might in turn be applied to the design of robotic swimmers. And yet, sharply contrasting views as to the energetic efficiency of oscillatory propulsion – especially for marine animals – demand a careful assessment of the forces and energy expended at realistic Reynolds numbers. For this and many other research questions, an experimental approach is often the most appropriate methodology. This holds as much for flying animals as it does for swimming ones, and similar experimental challenges apply – studying tethered as opposed to free locomotion, or studying the flow around robotic models as opposed to real animals. This book provides a wide-ranging snapshot of the state-of-the-art in experimental research on the physics of swimming and flying animals. The resulting picture reflects not only upon the questions that are of interest in current pure and applied research, but also upon the experimental techniques that are available to answer them.

Knochen! vereint die faszinierende Beschreibung von Bau und Funktion der menschlichen Knochen mit wunderschönen Farbfotografien, die ihre einzigartige Eleganz einfangen. R. McNeill Alexander, weltweit führender Experte für Biomechanik, nimmt den Leser mit auf eine Reise durch das menschliche Skelett mit seinen 213 Knochen. Das informative Buch führt uns die Natur der menschlichen Knochen ebenso vor Augen wie ihre Beziehung zu anderen Teilen des Körpers. Der Autor verdeutlicht zunächst, dass Knochen lebendige Organe sind -- sie wachsen, nehmen Schaden und verheilen genau wie andere Organe. Er macht uns dann mit Form und Funktion der unzähligen Knochen von Schädel, Gliedmaßen und Rumpf bekannt. Wie die Knochen des Armes gemeinsam mit Rumpf und Schulter einen großen Bewegungsradius schaffen, welche Beziehung die einzelnen Teile des Kopfes zueinander haben, etwa Nasen- und Mundhöhle - das sind nur einige wenige der vielfältigen Themen, die in diesem Buch behandelt werden. Interaktive Experimente erlauben es dem Leser, seinen eigenen Körper zu erforschen, und verhelfen zu überraschenden Einsichten. Auch warum die Knochen verschiedener Menschen unterschiedlich sind, wird von Alexander eingehend dargestellt. Dieses Wissen liegt der wichtigen Arbeit von Forensikern und Archäologen zugrunde - zum einen liefert es Informationen für jene Künstler, die Gesichter aus Schädeln rekonstruieren, zum anderen verrät die Zusammensetzung von Knochen einiges über das Leben von Individuen und ihre täglichen Gewohnheiten. Alexander stellt die Knochen immer wieder auch in einen stammesgeschichtlichen Zusammenhang, erklärt die Prinzipien der Evolution und ihre Auswirkungen auf die Frage des Nutzwertes, und er widmet schließlich ein ganzes Kapitel der evolutionären Beziehung zwischen den menschlichen Knochen und denen anderer Säugetiere. Aaron Diskins 115 Farbfotografien sind mehr als nur eine visuelle Ergänzung zu Alexanders fachkundigem und gut lesbarem Text - sie sind Kunstwerke, welche die bestechende Ästhetik menschlicher Knochen zeigen. Dies ist Ihr Körper. [Format 25 x 28 cm]
