Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth overview on the functional ecology of daily torpor and hibernation in endothermic mammals and birds. The reader is well introduced to the physiology and thermal energetics of endothermy and underlying different types of torpor. Furthermore, evolution of endothermy as well as reproduction and survival strategies of heterothermic animals in a changing environment are discussed. Endothermic mammals and birds can use internal heat production fueled by ingested food to maintain a high body temperature. As food in the wild is not always available, many birds and mammals periodically abandon energetically costly homeothermic thermoregulation and enter an energy-conserving state of torpor, which is the topic of this book. Daily torpor and hibernation (multiday torpor) in these heterothermic endotherms are the most effective means for energy conservation available to endotherms and are characterized by pronounced temporal and controlled reductions in body temperature, energy expenditure, water loss, and other physiological functions. Hibernators express multiday torpor predominately throughout winter, which substantially enhances winter survival. In contrast, daily heterotherms use daily torpor lasting for several hours usually during the rest phase, some throughout the year. Although torpor is still widely considered to be a specific adaptation of a few cold-climate species, it is used by many animals from all climate zones, including the tropics, and is highly diverse with about 25-50% of all mammals, but fewer birds, estimated to use it. While energy conservation during adverse conditions is an important function of torpor, it is also employed to permit or facilitate energy-demanding processes such as reproduction and growth, especially when food supply is limited. Even migrating birds enter torpor to conserve energy for the next stage of migration, whereas bats may use it to deal with heat. Even though many heterothermic species will be challenged by anthropogenic influences such as habitat destruction, introduced species, novel pathogens and specifically global warming, not all are likely to be affected in the same way. In fact it appears that opportunistic heterotherms because of their highly flexible energy requirements, ability to limit foraging and reduce the risk of predation, and often pronounced longevity, may be better equipped to deal with anthropogenic challenges than homeotherms. In contrast strongly seasonal hibernators, especially those restricted to mountain tops, and those that have to deal with new diseases that are difficult to combat at low body temperatures, are likely to be adversely affected. This book addresses researchers and advanced students in Zoology, Ecology and Veterinary Sciences.

Download or read book Hibernation and Torpor in Mammals and Birds written by Charles P Lyman and published by Elsevier. This book was released on 2013-07-10 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hibernation and Torpor in Mammals and Birds explores the physiological factors that control hibernation and torpor in birds and mammals. This text covers topics ranging from metabolism in hibernation to the role of endocrines, respiration and acid-base state in hibernation, and theories of hibernation. This book is comprised of 14 chapters and begins with an overview of some clear-cut definitions and why mammals and birds hibernate. The reader is then introduced to the variations from euthermia that have been observed among birds and mammals. To give some structure to this listing, the approach is phylogenetic, starting with the birds and proceeding through the primitive to the more advanced mammals. Subsequent chapters explains the process of entering hibernation and the hibernating state, itself; capability of a species in natural hibernation to arouse from that state using self-generated heat; physiological changes at the start of a spontaneous arousal; and physiological mechanisms underlying the ability of hibernators to rewarm. Consideration is also given to intermediary metabolism in hibernation, cold adaptation of metabolism in hibernators, and the response of hibernators to various extrinsic influences such as neoplastic growth, radiation injury, and parasitism and symbionts. This book will be of interest to students and researchers in fields ranging from zoology to physiology and biophysics.

Download or read book Natural Mammalian Hibernation written by William V. Mayer and published by . This book was released on 1964 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bibliography consists of over 2,100 references directly impinging upon natural mammalian hibernation, including a few references to birds and potential hibernators. A cross-referenced subject matter index makes it possible to locate with relative ease articles dealing with specific features of hibernation. The material was assembled over a number of years by detailed examination of library holdings, review literature, abstracting journals, The Zoological Record, B.A.S.I.C., and individual journals, and with the cooperation of fellow researchers in the field of natural mammalian hibernation. The assembled references were checked for their applicability for inclusion in this bibliography, alphabetized by author, and numbered for cross reference indexing. The parameters of the initial charge for making this bibliography have eliminated references to poikilothermous animals and most references to hypothermia, and have been the guidelines used to reduce some 7,000 references to the approximately one-third which finally comprise this bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: This review of the control of circulation during hibernation begins with a general description of hibernation as it occurs in various groups of mammals and outlines the difficulties in the physiological study of hibernation. There fol lows a more detailed description of the three phases of hibernation - entering hibernation, in deep hibernation, and waking from the hiber nating state. The bulk of the review concerns research on rodents, which have been the most intensively studied of the animals which hiber nate. It is emphasized that hibernation, at least in this groups, is a precisely controlled series of physiological changes in which the animal maintains a homeostatic condition at all times in spite of profound changes in body temperature.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarises the newest information on seasonal adaptation in animals. Topics include animal hibernation, daily torpor, thermoregulation, heat production, metabolic depression, biochemical adaptations, neurophysiology and energy balance. The contributors to this book present interdisciplinary research at multiple levels ranging from the molecular to the ecophysiological, as well as evolutionary approaches. The chapters of this book provide original data not published elsewhere, which makes it the most up-to-date, comprehensive source of information on these fields. The book’s subchapters correspond to presentations given at the 14th International Hibernation Symposium in August 2012 in Austria. This is a very successful series of symposia (held every four years since 1959) that attracts leading researchers in the field. Like the past symposia, this meeting – and consequently the book – is aimed not only at hibernation but at covering the full range of animal adaptations to seasonal environments. For the next four years, this book will serve as the cutting-edge reference work for graduate students and scientists active in this field of physiology and ecology. .

Download or read book Hibernation and the Hypothalamus written by Nicholas Mrosovsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammalian hibernation is commonly thought of as something completely out of the ordinary, a "unique and unorthodox state." The present book takes the opposite view. It argues that the physiological achievements of hibernators do not deEend on special mechanisms but on special use of ordinary mechanisms. It is precisely this that makes the hibernators important. If the hibernators de pend on some unique physiological principle their study is that of a biological curio. But if they are using basic mammalian systems in a quantitatively extreme way, then they are a naturally occurring preparation of enormous potential. Hibernation involves every aspect of the animal's biology from fat metabo lism to behavior, from thermoregulation to dental caries; every system in the body is affected in some way or other by hibernation. A comprehensive account of hibernation would be almost coextensive with an account of the whole of mammalian biology. The present book does not attempt to describe everything that has been discovered about hibernation. Excellent coverage for that already exists in the proceedings of three recent symposia and in the other major source materials listed on page 233. There is in fact an enormous amount of information already available. But there is a difference between information and understanding. Despite the increasing volume of research and growing interest in mammalian hibernation, there is little appreciation of the essential characteristics of the phenomena. The pieces of the puzzle lie scattered.

Download or read book Hibernation written by Clive Roots and published by Bloomsbury Publishing USA. This book was released on 2006-09-30 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: We share the earth with a wide variety of animal species, each of which brings something special to the diversity of the planet. By knowing more about how animals behave and live, we gain a greater understanding of how life evolved and the importance of biodiversity. Hibernation examines those animals that cannot migrate and are forced to remain in a habitat that is inhospitable and consequently sleep deeply for weeks or months. Known as hibernation for winter sleep and estivation for its summer equivalent, this unique trait involves many special behaviors — how do such animals prepare for sleep? where do they sleep? how do they store energy? how do they wake up? The book provides a thorough guide, perfect for research papers in biology classes, for understanding the behavior and biodiversity of a fascinating and unusual group of animals. Beautifully illustrated, with numerous color images, Hibernation provides copious material for understanding these unusual animals.

Download or read book Torpor and Hibernation Metabolic and Physiological Paradigms written by Sylvain Giroud and published by Frontiers Media SA. This book was released on 2024-06-21 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Torpor or heterothermy corresponds to a state of depressed metabolism and is associated with specific metabolic, cellular and molecular adaptations that often occur on a seasonal basis. Yet the exact mechanisms and functioning of these changes are poorly understood. Interestingly, the potential of such extraordinary animal adaptation for human and animal health as well as other biomedical considerations has raised particular attention especially in the last decade. The strong metabolic and physiological adaptations of heterotherms can be of particular inspiration for current biomedical and pathological situations (e.g., obesity and related diseases, cardiovascular and metabolic dysfunctions, ischemia-reperfusion injuries, immune depression) and for the health and longevity of animal species, including humans.

This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: When survival is challenged by the cold, animals react by employing both behavioral and physiological solutions. Depending on the magni tude of the cold stress and the nature of the adjustment, simple avoidance or sophisticated capacity or resistance compensations may be used. Thus, migration, shelter seeking, metabolic and insulative compen sation, torpor, and freezing avoidance and tolerance are successful tac tics used by diverse groups of animals. To understand and appreciate the benefits of these tactics, it is necessary to examine not only the well being of the whole animal but also their basic underlying mechanisms. In ad dition, it is also of fundamental importance to grasp how seasonal cold affects the survivorship and reproductive success of populations when confronted by a general reduction in primary productivity and an elevated energy cost for maintenance (e. g. in endotherms). In this regard, a synthetic overview which integrates aspects of cell biology, biochem istry, physiology, neurobiology, behavior, and population biology should be a fruitful approach in providing a holistic understanding on how animals adapt to cold. The present volume is an attempt to achieve such an overview; its objective is to provide a depth and breadth of coverage that is essential to a full appreciation of animal adaptation to cold. It is the hope of the contributing authors that this book will serve as an effective reference text for all senior undergraduate and graduate students as well as research scientists with an interest in cold physiology.

Download or read book Patterns of Vertebrate Biology written by E.W. Jr. Jameson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book grew from a series of lectures on vertebrate natural history. The topics have been developed over a period of nearly 30 years, and today scarcely resemble the original subject matter. The progress is primarily technical. Some concepts provide a synthetic framework for viewing much modern research, but many of these concepts either date from Darwin or have developed from obser vations of later students. Animal science courses follow a sequential pattern in which there are three discrete levels of undergraduate instruction. Initially, students study subject mat ter contained in such courses as biology and general zoology. These courses intro duce students to animal phylogeny, basic plans of morphology and certain phys iological aspects; incidental to these subjects the student acquires a broad zoological vocabulary. At the other end of the academic spectrum are courses that emphasize synthe sis and theory: evolution, zoogeography, behavior and ecology are important courses whose role is to explore the relationships of various aspects of the physical and biological world. In these courses theory and analysis prevail. They are not, however, essentially "subject matter" courses with distinct bodies of knowledge.
