Download or read book Ecological Physiology of Daily Torpor and Hibernation written by Fritz Geiser and published by Springer Nature. This book was released on 2021-08-23 with total page 326 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to translate insights from the physiology of natural hibernators to a model of artificial hibernation that could aid clinical applications. In Part I, the governing physiological elements that are responsible for the induction of (artificial) hibernation are discussed. Chapter 1 presents a model that identifies the necessary physiological changes for induction of artificial hibernation. Chapter 2 dives deeper into (bio)chemical and pharmacological agents with thermoregulatory properties. In Part II, the effects of a popular biochemical agent, hydrogen sulfide (H2S), are evaluated for its potential to induce artificial hibernation in large and small animals. Chapter 3 starts with a series of experiments in large animals (pigs), studying the systemic effects of H2S. Chapter 4 goes back to a small-animal model (mice) and compares the effects of H2S to the more potent effects of hypoxia for the induction of artificial hibernation. Part III ends with a description of practical systems and strategies for bringing this model to single organ application in the liver. Chapter 5 describes the necessary preparations to the liver to maintain stable extracorporeal hepatic physiological function. The final chapter demonstrated how several of the model’s elements can be controlled in an extracorporeal environment.

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.

Download or read book Living in a Seasonal World written by Thomas Ruf and published by Springer Science & Business Media. This book was released on 2012-04-23 with total page 549 pages. 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. .

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the 11 'h international symposium dedicated to the understanding of animal "Life in the Cold", held at Jungholz (Austria), August 13-18, 2000. In 55 chapters contributed by researchers from 16 countries the current state of knowledge is reviewed, and the most recent developments and discussions in this field are highlighted. The first symposium on hibernation and life in the cold was held in 1959, and from then on they continued to occur every 3-5 years. The regular occurrence of these meetings became almost a tradition. A tradition which is entirely based on the enthusiasm of participants, and was nourished by scientific progress in this area during the past decades. The first symposium in 1959 was organised by Charles P. Lyman and Albert R. Dawe and was almost entirely dedicated to hibernation and torpor. This has been a backbone topic of the following symposia, although other aspects of animal energetics, thermal physiology and biochemistry were included in later meetings.

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.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hibernation represents a seasonal physiological adaptation, which allows conservation of energy and down-regulation of cellular functions. Hibernating animals exhibit multiple biological alterations which contribute to their dramatic ability to tolerate the ischaemic conditions associated with reduced rates of respiration and blood flow while in the hibernating state. There is accumulating evidence that mammalian hibernation involves a controlled suppression of interactive physiological responses that preserves homeostatic balance. Mammalian hibernation is a regulated state of torpor with a profound suppression of energy requirements that has evolved in at least six mammalian orders as a strategy to cope with seasonal cold and shortages of food and water (Wang, 1988). A hibernation bout may last up to several weeks in some mammals and consists of entry into, maintenance of, and arousal from hibernation. Arousal is maintained for a few hours to a few days before the animal initiates another bout of hibernation.
