Download or read book Allostasis Homeostasis and the Costs of Physiological Adaptation written by Jay Schulkin and published by Cambridge University Press. This book was released on 2004-10-25 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of homeostasis, the maintenance of the internal physiological environment of an organism within tolerable limits, is well established in medicine and physiology. In contrast, allostasis is a relatively new idea of 'viability through change'. With allostatic regulation by cephalic involvement, the body adapts to potentially diverse and dangerous situations through the activation of neural, hormonal, or immunological mechanisms. Allostasis explains how regulatory events maintain organismic viability, or not, in diverse contexts with varying set points of bodily needs and competing motivations. This 2005 book introduces the concept of allostasis and sets it alongside traditional views of homeostasis. It addresses basic regulatory systems and examines the behavior of bodily regulation under duress. The basic concepts of physiological homeostasis are integrated with disorders like depression, stress, anxiety and addiction. It will therefore appeal to graduate students, medical students and researchers working in physiology, epidemiology, endocrinology, neuroendocrinology, neuroscience, and psychology.
Download or read book Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment written by Parvaiz Ahmad and published by Springer Science & Business Media. This book was released on 2013-11-12 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global population is growing at an alarming rate and is anticipated to reach about 9.6 billion by the end of 2050. Addressing the problem of food scarcity for budding population vis-à-vis environmental changes is the main challenge plant biologists face in the contemporary era. Plant growth and productivity are scarce in many areas of the world due to a wide range of environmental stresses. The productive land is dwindling progressively by various natural and anthropogenic means that lead to enormous crop losses worldwide. Plants often experience these stresses and have the ability to withstand them. However, when the stress exceeds the normal tolerance level, plants accumulate organic osmolytes, osmoprotectants, cryoprotectants and antioxidant enzymes, which helps them tolerate these stresses and assist in their acclimatization towards the particular ambiance needed for maintaining their growth and development. Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 discuss drought and temperature stresses and their mitigation through different means. This volume illuminates how plants that are bombarded by diverse and changing environmental stimuli, undergo appropriate physiological alterations that enable their survival. The information covered in the book is also useful in building apposite strategies to counter abiotic and biotic stresses in plants. Written by a diverse group of internationally renowned scholars, Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 is a concise yet comprehensive resource that will be beneficial for the researchers, students, environmentalists and soil scientists of this field.
Download or read book Physiological Adaptations for Breeding in Birds written by Tony D. Williams and published by Princeton University Press. This book was released on 2012-08-05 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological Adaptations for Breeding in Birds is the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness. The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.

Book excerpt: Adaptation to Environment: Essays on the Physiology of Marine Animals contains a series of essays that is intended as a review of the special adaptations of marine organisms to the particular environmental conditions they are likely to encounter in the natural habitat. This book emphasizes developments in physiology of marine animals and on approaches to the study of the adaptations of marine organisms. This compilation also interprets the term “Physiology in its widest sense to include all aspects of the functioning of the organism from the behavior of animals to the mode of function of enzymes. For this reason, structural adaptations have been reviewed in detail only where their functional role is understood and where they constitute a specific adaptation to defined environmental conditions. This publication benefits students and individuals conducting research on the physiology of marine animals.

Download or read book Advances in Comparative and Environmental Physiology written by Lawrence C.H. Wang and published by Springer Science & Business Media. 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 Physiological Adaptations to Swimming in Fish written by Josep V. Planas and published by Frontiers Media SA. This book was released on 2017-08-16 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

This book was released on 2013-10-22 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals and Environmental Fitness: Physiological and Biochemical Aspects of Adaptation and Ecology, Volume 2 contains the proceedings of the First Conference of the European Society for Comparative Physiology and Biochemistry held in Liège, Belgium, on August 27-31, 1979. The papers explore the physiology and biochemistry of animal adaptation and ecology and cover topics ranging from amino acid transport and metabolism during osmotic shock to the role of organic compounds in osmoregulation in plants and animals. This volume is comprised of 89 chapters and begins with an analysis of the transport and metabolism of amino acids under osmotic stress, followed by a discussion on cell volume regulation in isolated heart ventricles from the flounder, Platichthys flesus, perfused with anisosmotic media. Subsequent chapters focus on the effects of cholinergic drugs on the osmotic fragility of erythrocytes; strategies of osmoregulation in the fiddler crab Uca pugilator; ionic regulation in the African catfish Clarias mossambicus in water and air; and environmental and endocrine factors controlling osmotic water fluxes in gills of Sarotherodon (tilapia) mossambicus. The effect of seawater adaptation on the phosphatidyl-choline metabolism in the eel is also considered, along with evaporative water loss in anuran amphibians. This book will be of value to zoologists, physiologists, biologists, and biochemists.
