Book Description
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.

Book Description
Volume 5 of this series continues its coverage of currently active re search fields in ornithology. Because an editor can never be a disin terested observer of his or her own editorial efforts, any claim for su periority of this volume is not without conflict of interest. Even so, Volume 5 has certain merits that even a parent should acknowledge, and I find the current chapters not merely timely and authoritative but compelling in their demand for a reader's attention. Wolfgang and Roswitha Wiltschko provide a perceptive review of magnetic orientation in birds, a piece dedicated to Fritz Merkel, the pioneer in studies of magnetic orientation. Sergei Kharitonov and Doug las Siegel-Causey are concerned with the behavioral ecology of seabird coloniality, emphasizing their field experiences in the USSR and the United States. Ted Miller examines the application of studies of bird behavior to comparative biology, pursuing the interface of behavior and evolutionary biology adumbrated by Konrad Lorenz in the 1930s. Jeremy Raynor gives us a summary of the work over the past decade on bird flight, which is not, by turns, as complex or as simple as we had formerly believed. Carrol Henderson describes recent develop ments in nongame bird conservation, based on his pioneering work in the State of Minnesota. Alan Kamil discusses optimal experimental design for research in ornithology, a field in which experimental work is frequently difficult to pursue.

Book Description
The Ornithopoda, one of five suborders within the Ornithischia, was originally proposed by Marsh in 1881 to include those bipedal dinosaurs possessing a predentary bone fitted over the rostral end of the mandibles. Ornithopods as recognized today can be further characterized by moderately long facial skele tons equipped with well-developed, often toothless premaxillae and moderate to large external nares. Maxillary and dentary dentitions vary but usually consist of at least one replacement series beneath the functional set; some have many rows of successional teeth. Tooth morphology suggests ornithopods were suc cessful herbivores but, as will be discussed, the precise way(s) in which ornitho pods chewed their food, hence lending important information about their tro phic position, has not been settled. Postcranially, ornithopods show specializa tion for bipedality in hindlimb construction and lack well-developed protective structures on their flanks, back, and tail. The Ornithopoda can itself be divided into five families: Fabrosauridae, He terodontosauridae, Hypsilophodontidae, 19uanodontidae, and Hadrosauridae (subdivided into the subfamilies Hadrosaurinae and Lambeosaurinae). Both fabrosaurids and heterodontosaurids, first known from the Late Triassic and Early Jurassic of Argentina and South Africa, were small animals differing in details of cranial, dental, and appendicular anatomy. Fabrosaurids are be lieved to represent the basal ornithopod stock (Galton 1972, 1978; Thulborn 1970a, 1972). During the Jurassic, ornithopods underwent major radiations that included the medium- to large-sized Hypsilophodontidae and the large bodied Iguanodontidae, both of which survived into the Cretaceous.

Book Description
This book provides students and researchers with reviews of biological questions related to the evolution of feeding by vertebrates in aquatic and terrestrial environments. Based on recent technical developments and novel conceptual approaches, the book covers functional questions on trophic behavior in nearly all vertebrate groups including jawless fishes. The book describes mechanisms and theories for understanding the relationships between feeding structure and feeding behavior. Finally, the book demonstrates the importance of adopting an integrative approach to the trophic system in order to understand evolutionary mechanisms across the biodiversity of vertebrates.
