Hormones and Reproduction of Vertebrates, Volume 3
Author: David O. NorrisPublisher: Elsevier
ISBN: 0443160236
Category : Science
Languages : en
Pages : 398
Book Description
Hormones and Reproduction of Vertebrates, Volume 3: Reptiles is the third of five second-edition volumes representing a comprehensive and integrated overview of hormones and reproduction in fishes, amphibians, reptiles, birds, and mammals. The book includes coverage of endocrinology, neuroendocrinology, physiology, behavior, and anatomy of reptilian reproduction. It provides a broad treatment of the roles of pituitary, thyroid, adrenal, and gonadal hormones in all aspects of reproduction, as well as descriptions of major life history events. New to this edition is a concluding assessment of the effect of environmental influences on reptiles. Initial chapters in this book broadly examine sex determination, reproductive neuroendocrinology, stress, and hormonal regulation as it relates to testicular and ovarian function. Subsequent chapters examine hormones and reproduction of specific taxa, including turtles, crocodilians, lizards, and snakes. The book concludes with an examination of endocrine disruption of reproduction in reptiles. Hormones and Reproduction of Vertebrates, Volume 3: Reptiles is designed to provide a readable, coordinated description of reproductive basics in reptiles, as well as an introduction to the latest trends in reproductive research and a presentation of our understanding of reproductive events gained over the past decade. It may serve as a stand-alone reference for researchers and practitioners in the field of herpetology or as one of five coordinated references aligned to provide topical treatment across vertebrate taxa for researchers, practitioners, and students focused on vertebrate endocrinology. - Covers endocrinology, neuroendocrinology, physiology, behavior, and anatomy of reptile reproduction - Includes pituitary, thyroid, adrenal, and gonadal hormones - Focuses on turtles, crocodilians, lizards, and snakes - Provides new coverage on environmental influences on reptiles
Is the Dewlap an Honest Signal of Fighting Ability in the Male Green Anole (Anolis Carolinensis)?

Book Description
Signals are morphological or behavioral traits that an individual uses to influence the behavior or actions of another. These signals can be used in male-male competition, in which male secondary sexual traits act as a signal of his fighting ability. Animal signals are considered honest when the signal reliably indicates a specific trait or condition of the individual. The genus Anolis, comprised of over 400 species that occupy the tropics and the southeastern United States, utilize aggressive signaling prior to physical combat. Research on several tropical species of anole indicates that the size of their dewlap can act as an honest signal of their fighting ability, as dewlap size is correlated with the chance of an individual winning in combat. No studies of this nature, however, have been done for the green anole, Anolis carolinensis. In this study, I measured the size of adult male green anole's dewlaps, their bite forces, and performed dyadic interactions between two males matched for body size to determine if the dewlap can be considered an honest signal of fighting ability. I found that dewlap size, mean bite force, and maximum bite force did not differ between winners and losers of dyadic interactions. However, latency to bite did differ between winners and losers, and there was a predictive relationship between dewlap size and latency to bite. These results could be explained by the different personalities of male green anoles, specifically regarding an individual's level of boldness. Being bold in a high-risk situation, such as in male-male competition, is dangerous for an individual and comes with the chance of injury or death. The dewlap of the male green anole could potentially act as an honest signal of his cautiousness, and his hesitancy to engage in male-male competition, but also his confidence in his capacity to defeat his opponent if the conflict reaches the actual combat stage. -- Abstract, leaves i-ii
Hormones and Reproduction of Vertebrates

Pages : 1681
Book Description
This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided. A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them
