This book was released on 2012-12-06 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Download or read book Intersexuality in the Animal Kingdom written by R. Reinboth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organisms the reproductive system has a unique importance for the perpetuation of the species. Conversely, reproductive processes are of little or no account for the viability of the individual. Therefore, within the framework of general biology reproduction has all too often been looked at solely from the point of view of genetics. Lively discussions about genotypic versus phenotypic sex determination long dominated the sci entific literature on sexuality in animals; this one-sided emphasis has tended to obscure many important facets of an organism's ability to reproduce. Recent developments in current biological research have brought the classic problem of sex differentiation into focus again, and the rapid progress being made in comparative endocrinology has added a new di mension to the study of reproductive biology.

Download or read book Comparative Endocrinology of Animals written by Edward J Narayan and published by BoD – Books on Demand. This book was released on 2019-07-31 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the editor has reviewed the scientific articles from a diverse group of scientists from around the world who actively participate in comparative endocrinology. Some of the important categories represented here are human health, aquaculture, wildlife conservation, and production animals. Eminent scientists write from their experience, providing an overview of the current information on comparative endocrinology of animals. The chapters also provide valuable information for animal production and human health management. The book will be useful to biologists, biomedical researchers, veterinary students, wildlife managers, researchers, and wildlife conservationists.

This book was released on 2018-02-10 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Color Changes of Animals in Relation to Nervous Activity The present volume is a somewhat extended form of the Joseph Leidy Memorial Lecture in Science delivered at the University of Pennsylvania March 3, 1936. In ad dition to the historical summaries it con31sts in large part of the recent studies by my students and myself on the means of activating color-cells in the higher ani mals and on the significance of these processes for the workings of the nervous system. It is believed that the idea of the neurohumors, set forth in numerous earlier publications and rather fully elucidated in this volume, has a measure of truth in it for general nervous func tions, and it is one of the objects of this essay to point out some of the reasons for accepting this idea and for testing its further applications. The whole proposal 1s quite obviously in a formative stage and, as every inves tigator knows, its outcome must await further study. The invitation to deliver the Leidy lecture came to me from a committee consisting of Dr. Josiah H. Penni man, Provost of the University of Pennsylvania, Dr. Eliot Clark, Dr. Milton Greenman, and Dr. C. E. Mcclung. To these gentlemen I wish to express my keen appreciation of the honor of this invitation and the great pleasure I take in accepting it. A certain personal gratification that I feel in this acceptance I have at tempted to indicate in the Foreword.

Download or read book Color Change Mechanisms of Cold blooded Vertebrates written by Horace Harry Waring and published by . This book was released on 1963 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Color Change Mechanisms of Cold-Blooded Vertebrates focuses on color change in vertebrates and its relation to endocrine control. The book first tackles physiological color changes in amphibians, elasmobranchs, teleosts, and cyclostomes. Topics include description of responses, nonvisual response, criticisms of the two-hormone hypothesis as applied to amphibians and elasmobranchs, and summary of teleost color change mechanisms. The publication then elaborates on physiological color changes in reptiles and biological assay of melanin-dispersing hormones, as well as generalities about reptilian color change, general statement on biological assay, and theoretical considerations. The manuscript ponders on the chemistry of melanin-dispersing hormones, mechanism of the melanophore, and actions of melanin-dispersing hormones on functions other than color change. Discussions focus on glandular origin of melanin-dispersing hormones, energy sources for melanin movement, and metabolism.
