Book Synopsis Hibernation and Torpor in Mammals and Birds by : Charles P Lyman
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.

Book Synopsis Torpor and Hibernation: Metabolic and Physiological Paradigms by : Sylvain Giroud
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.

Book Synopsis Expression and Mechanisms of Hibernation in the Arctic by : Trixie Nicole Lee
Download or read book Expression and Mechanisms of Hibernation in the Arctic written by Trixie Nicole Lee and published by . This book was released on 2012 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is home to animals that have taken adaptations to overwintering to extremes. In this dissertation, I have investigated one of these adaptations, hibernation, in two species from the Arctic, the Alaska marmot (Marmota broweri) and the arctic ground squirrel (Urocitellus parryii). The expression of hibernation under natural conditions in these species was compared by collecting body temperature records of free-living individuals. The Alaska marmot, a highly social species, demonstrated extreme synchrony in body temperature patterns among a family group, indicating a strong reliance on social thermoregulation. In contrast, the arctic ground squirrel was confirmed to be a solitary hibernator that reduces body temperature below freezing during torpor. Both species must produce heat when soil temperatures are significantly below freezing for most of the winter. At these subfreezing ambient temperatures, the arctic ground squirrel has shown an increasing reliance on nonlipid fuel during torpor, driving a loss of lean mass during hibernation of ~20%. I calibrated deuterium dilution to repeatedly estimate body composition in this species, which dramatically changes adiposity through its annual cycle, and used this technique to quantify lean mass loss throughout hibernation in a study of tissue metabolism. I also developed and applied the natural abundance of nitrogen and carbon stable isotopes as tools for monitoring differential tissue metabolism and differentiating mixed metabolic fuel use in the arctic ground squirrel. These data clarified the mechanism of change in nitrogen stable isotopes andd, indicated that hibernating ground squirrels rebuild organ tissues while breaking down muscle tissue to meet energetic demands. Furthermore, I corroborated a shift in metabolic fuel use toward nonlipid sources during torpor at low ambient temperatures by using the carbon isotope ratio in exhaled breath in combination with respiratory quotient. This dissertation combines studies of hibernation patterns in free-living animals with experimental data on the tissues and fuels being catabolized at very low temperatures to broaden our understanding of how small mammals successfully hibernate in severe winter conditions. It also presents the development and use of stable isotope ratios as physiological tools in hibernating species.

Book Synopsis Survival Strategies in Extreme Cold and Desiccation by : Mari Iwaya-Inoue
Download or read book Survival Strategies in Extreme Cold and Desiccation written by Mari Iwaya-Inoue and published by Springer. This book was released on 2018-10-04 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively describes biological phenomena, adaptation mechanisms, and strategies of living organisms to survive under extremely cold or desiccated conditions at molecular, cellular, and organ levels. It also provides tremendous potential for applications of the findings to a wide variety of industries. The volume consists of three parts: Part 1, Adaptation Mechanisms of Cold, and Part 2, Adaptation Mechanisms of Desiccation, collect up-to-date research on mechanisms and strategies of living organisms such as sleeping chironomids, polar marine fishes, hibernating mammals, bryophytes, dormant seeds, and boreal plants to survive under extreme cold and desiccated conditions at molecular, cellular, and organ levels. Part 3, Application Technologies from Laboratory to Society, covers various applications to a wide variety of industries such as the medical, food, and agricultural and life science industries. For example, biological knowledge of how plants and animals survive under cold, drought, and desiccated conditions may provide a hint on how we can improve crop production in a very fragile environment in global climate change. Unique molecules that protect cells during desiccation and freezing such as trehalose and antifreeze protein (AFP) have potential for use to preserve cells, tissues, and organs for the long term under very stable conditions. In addition, the current progress of supercooling technology of cells may lead us to solve problems of cellular high sensitivity to freezing injury, which will dramatically improve the usability of these cells. Furthermore, knowledge of water substitution and glass formation as major mechanisms for formulation designs and new drying technologies will contribute to the development of food preservation and drug delivery systems under dry conditions. Written by contributors who have been conducting cutting-edge science in related fields, this title is recommended to a wide variety of readers who are interested in learning from such organisms their strategies, mechanisms, and applications, and it will inspire researchers in various disciplines.
