This volume presents a broad comparative anatomical approach towards the functional morphology of the middle ear of palaeognathous birds (ostrich, rhea, tinamous, emu, cassowary, kiwi) and basal neognathous birds. It presents the most complete and thoroughly studied source of material on this field. For the first time it became possible to develop exact images of "non-structures" like the air-filled spaces of the avian skull by using non-invasive CT-techniques, computer-aided 3D-reconstruction, and morphometry, and to evaluate their functional importance for sound transmission and amplification through the middle ear. A series of air brush drawings represent detailed three-dimensional images of middle ear structures and the pneumatic spaces of the octic region of the skull.

This volume focuses on the history of research on hearing from comparative approaches. Each chapters examines the most formative studies that led to current understanding of hearing across taxa and still influence hearing research in general. Much of the early work on hearing, which goes back to Aristotle, as well as the classic work of 16th to early 20th century scientists (e.g., Spellanzani, Retzius, Ramón y Cajal, and Helmholtz) is not well known to modern investigators. Similarly, work in the first 75 years of the 20th century is also unknown or, in some cases, dismissed because it is “old.” Much of the earlier work describes research approaches and results fundamental to our understanding of hearing as well as the beauty of observation and synthesis. The pioneering work on hearing contains ideas and questions that are still germane today. Thus, the goal of this volume is to introduce, review, and put into perspective, older but exemplary, extraordinary studies by investigators that form the basis of our knowledge as well as questions being asked today. Each chapter includes the first significant observations and approaches to hearing in the taxa and/or hearing type that is the focus of the chapter with some of the most important earlier papers discussed in some detail, including the theories, formative experiments, results, and conclusions. Each chapter provides briefer notations and citations of additional important papers that are outgrowths of the founding research – or correlate and even reverse the original works. This volume is a departure from the classic approach established for the SHAR books in which the focus has been on a single topic, and on the most recent and exciting discoveries. One difference in this volume from past SHAR volumes is that we have a more coordinated approach for the chapters to ensure that this volume is, indeed, a documentation of hearing research history, not a review of the latest status of the topic. A second difference is that the focus of the volume is on the historical value of studies. In that sense, the volume maintains the tutorial value for which SHAR books are famous, but it explores the ancestry of modern research in order to help new researchers to gain perspective on important questions and on fundamental information they may not fully appreciate – to their loss. Our interest in doing this volume comes from phenomena familiar to most senior investigators - that younger investigators often have little or no sense of the history of their discipline, and they often do not know that their “hot” new idea was not only pursued, and often solved, but further that it was solved in an elegant way. We believe it is important to bring the methodologies and discoveries on hearing done before the advent of the internet to light, for the benefit and growth of new research. In deciding on the chapter divisions for this book, we considered a number of different organizational schemes, and particularly using as a focus methodological approaches (e.g., psychoacoustics, low to high frequency types, physiology, anatomy). However, we came to the conclusion that most investigators tend to be more focused on working within a particular taxonomic group, settling on particular taxa, in many cases driven by the special hearing abilities. We also concluded that that this approach is more naturally related to the evolution not only of hearing, but also to the evolution of ideas, as much of hearing science was part of the “natural philosopher” approach that was a core element of historical discoveries.

As the first four-legged vertebrates, called tetrapods, crept up along the shores of ancient primordial seas, feeding was among the most paramount of their concerns. Looking back into the mists of evolutionary time, fish-like ancestors can be seen transformed by natural selection and other evolutionary pressures into animals with feeding habitats as varied as an anteater and a whale. From frog to pheasant and salamander to snake, every lineage of tetrapods has evolved unique feeding anatomy and behavior.Similarities in widely divergent tetrapods vividly illustrate their shared common ancestry. At the same time, numerous differences between and among tetrapods document the power and majesty that comprises organismal evolutionary history.Feeding is a detailed survey of the varied ways that land vertebrates acquire food. The functional anatomy and the control of complex and dynamic structural components are recurrent themes of this volume. Luminaries in the discipline of feeding biology have joined forces to create a book certain to stimulate future studies of animal anatomy and behavior.

The central focus of this book is the avian respiratory system. The authors explain why the respiratory system of modern birds is built the way it is and works the way that it does. Birds have been and continue to attract particular interest to biologists. The more birds are studied, the more it is appreciated that the existence of human-kind on earth very much depends directly and indirectly on the existence of birds. Regarding the avian respiratory system, published works are scattered in biological journals of fields like physiology, behavior, anatomy/morphology and ecology while others appear in as far afield as paleontology and geology. The contributors to this book are world-renowned experts in their various fields of study. Special attention is given to the evolution, the structure, the function and the development of the lung-air sac system. Readers will not only discover the origin of birds but will also learn how the respiratory system of theropod dinosaurs worked and may have transformed into the avian one. In addition, the work explores such aspects as swallowing mechanism in birds, the adaptations that have evolved for flight at extreme altitude and gas exchange in eggs. It is a highly informative and carefully presented work that provides cutting edge scientific insights for readers with an interest in the respiratory biology and the evolution of birds.
