Available in PDF, EPUB and Kindle. Book excerpt: In this groundbreaking scientific study, W.H. Bergtold offers a comprehensive analysis of the incubation periods of a wide variety of bird species. Drawing on data collected over many years of research, Bergtold provides a detailed account of how different factors-such as temperature, humidity, and nesting habits-can affect the length of an egg's incubation period. The book also includes many fascinating observations about the behavior and physiology of various bird species, and offers insights into the evolutionary processes that have shaped their reproductive biology. This is an essential resource for anyone interested in avian biology, or in the broader field of evolutionary biology.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Study of the Incubation Periods of Birds: What Determines Their Lengths? In the course of certain studies in ornithology, more particularly avian physiology, undertaken by the author several years ago, it early became apparent that the factors fixing or determining the length of the incubation period with different birds was largely, if not wholly, unknown. The following pages give the results of a prolonged and detailed study of this phase of bird physiology. The author regards all zoologic classification as a means, not an end; the classification adopted in this work is merely a means of facilitating the handling of a mass of data full of contradictions and uncertainties, and the selection of this particular bird classification was governed by a question of expediency only; obviously the author in no way wishes to be understood as believing this classification to be the best, or the only one. The author believes, however, that this classification is an up-to-date reflection of our present knowledge of the relation of vario'us birds to each other. It is inevitable that mistakes of various sorts will be found in this book; in extenuation of such errors the author trusts that his critics will recall that the labor involved in the investigations reviewed in the following pages was one of love, and carried on in the spare moments of a fairly busy professional life. A brief resume of pages 43 to 76 of this book was read before the Annual Meeting of the American Ornithologists' Union at Philadelphia, November 15, 1916.

Download or read book Nests Eggs and Incubation written by D. Charles Deeming and published by OUP Oxford. This book was released on 2015-08-13 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nests, Eggs, and Incubation brings together a global team of leading authorities to provide a comprehensive overview of the fascinating and diverse field of avian reproduction. Starting with a new assessment of the evolution of avian reproductive biology in light of recent research, the book goes on to cover four broad areas: the nest, the egg, incubation, and the study of avian reproduction. New research on nest structures, egg traits, and life history is incorporated, whilst contemporary methodologies such as self-contained temperature probes and citizen science are also discussed. Applied chapters describe how biological knowledge can be applied to challenges such as urbanisation and climate change. The book concludes by suggesting priorities for future research. This book builds upon the foundations laid down by Charles Deeming's 2002 work Avian Incubation (available for readers of this book to access online for free), much of which remains relevant today. Read in conjunction with this previous volume, it provides an up-to-date and thorough review of egg biology, nest function, and incubation behaviour, which will be an essential resource for students of avian biology, as well as both professional and amateur ornithologists working in the field of avian reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: This book reviews comprehensively incubation effects on embryonic development in birds and reptiles and presents the first ever synthesis of data from these two vertebrate classes. The book is in three parts. The first deals with the structure, shape and function of eggs. The second examines the effects of the four main parameters on the process of incubation: temperature, water relations, respiratory gas exchange, and turning. The third section deals with early embryonic development and the methods used to investigate and manipulate the embryo. Further chapters deal with aestivation, megapodes and oviparity. International experts in each field have contributed to this extensively referenced volume and it will be of great interest not only to research biologists, but also to bird and reptile breeders, whether in commercial organisations or in zoos.
