Available in PDF, EPUB and Kindle. Book excerpt: In this book we have described the major events of embryonic development and considered the underlying mechanisms which result in the production of a viable hatchling. We have, as the subtitle of the book indicates, con centrated on behavioural and physiological topics: it is not our purpose to consider the early embryology of the bird - which is adequately covered by other texts - but we have included morphogenetic information where appropriate. The form of the book was dictated by a belief that interest in this aspect of development is not confined to embryologists, biochemists and physiolo gists. Therefore after describing the conditions in which the egg normally develops we have considered first the whole embryo: what it is like at different stages, what it does, how it gets from one position to another within the shell and how, later, it comes to interact with the wider environ ment of the nest. Only after this have we considered the development of the nervous and sensory mechanisms on which this transformation depends and on the problem of the level of behavioural maturity with which the chick emerges from the egg. With the main lines of development described we have, in the second part of the book, turned to a detailed consideration of the physiology of development: ranging from what may be conveniently described as the 'life-support' systems - gaseous exchange, provision of energy, etc. - to the of hormones in avian development.

Book excerpt: The use of indirect calorimetry to measure the heat production of men and animals has increased rapidly since the pioneering work of Lavoisier. Measurement of the consumption of oxygen and production of carbon dioxide are the basis for the measurement of heat production. Today, applications of indirect calorimetry are available in many species. Combining these measurements with accurate climate control, recording of physical activity and feed intake, use of stable isotopes and sophisticated modelling techniques allow scientists to make progress in various research areas. This book provides a scientific basis for indirect calorimetry, dealing with smart ways to design calorimeters, gas measurements and computational techniques to deal with complex data. Novel techniques allow the connection between short term changes in energy expenditure, protein turnover and substrate oxidation, e.g. using stable isotopes. Various applications of indirect calorimetry are addressed, including heat production measurements in growing animals, hatching eggs, companion animals and in animals housed under heat stress conditions. In addition, various ways of measuring methane emissions are discussed. This book is intended for scientists working or interested in calorimetry or metabolism research, or people designing calorimetry systems, opening their eyes for applications they did not yet think of.

Download or read book Avian Biology written by Donald S. Farner and published by Academic Press. This book was released on 2013-09-17 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Biology, Volume V is a collection of papers that deals with the biology of birds concerning their mechanics of flight and migration. The first paper describes the mechanics of bird flights such as gliding, soaring, and the energy requirements of this activity. Other papers investigate the control and metabolic physiology of migration, including flight restlessness and fat metabolism. Other topics cover migratory orientation research involving topographical, meteorological, inertial, magnetic, and celestial cues. Upon migration to different environments, birds have to adapt as their circadian and circannual rhythms are affected. One paper discusses the works of Wynne-Edwards, Aschoff and Wever, and Leopold and Eynon regarding their observations of bird migration cues. One author describes the vocal behavior in birds, including the dual sound theory where two sound sources can occur in each bronchus. Of interest to many in this paper is the description of the different stages in song development. Other papers discuss the incubation behavior of birds as well as the energetics involved. This book is suitable for zoologists, bird enthusiasts, and avian biologists.
