Beschreibung
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 dinosaursworked 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.
Autorenportrait
John N. Maina served as a professor of veterinary anatomy for 17 years at the University of Nairobi (Kenya) and of human anatomy for 13 years at the University of the Witwatersrand (South Africa). He currently works as a research professor at the University of Johannesburg. He hasbeen investigating the structure of the avian respiratory system for nearly four decades and published 150 papers in peer reviewed journals, 12 book chapters and 5 books on the comparative functional design of the gas exchangers. He has collaborated with others both nationally and internationally, held appointments in various academic institutions and has been invited to give lectures at different meetings/conferences and academic institutions. He has lectured in courses pertaining to the structure and function of the animal and the human bodies.

Informationen zu E-Books
„E-Book“ steht für digitales Buch. Um diese Art von Büchern lesen zu können wird entweder eine spezielle Software für Computer, Tablets und Smartphones oder ein E-Book Reader benötigt. Da viele verschiedene Formate (Dateien) für E-Books existieren, gilt es dabei, einiges zu beachten.
Von uns werden digitale Bücher in drei Formaten ausgeliefert. Die Formate sind EPUB mit DRM (Digital Rights Management), EPUB ohne DRM und PDF. Bei den Formaten PDF und EPUB ohne DRM müssen Sie lediglich prüfen, ob Ihr E-Book Reader kompatibel ist. Wenn ein Format mit DRM genutzt wird, besteht zusätzlich die Notwendigkeit, dass Sie einen kostenlosen Adobe® Digital Editions Account besitzen. Wenn Sie ein E-Book, das Adobe® Digital Editions benötigt herunterladen, erhalten Sie eine ASCM-Datei, die zu Digital Editions hinzugefügt und mit Ihrem Account verknüpft werden muss. Einige E-Book Reader (zum Beispiel PocketBook Touch) unterstützen auch das direkte Eingeben der Login-Daten des Adobe Accounts – somit können diese ASCM-Dateien direkt auf das betreffende Gerät kopiert werden.
Da E-Books nur für eine begrenzte Zeit – in der Regel 6 Monate – herunterladbar sind, sollten Sie stets eine Sicherheitskopie auf einem Dauerspeicher (Festplatte, USB-Stick oder CD) vorsehen. Auch ist die Menge der Downloads auf maximal 5 begrenzt.
