Available in PDF, EPUB and Kindle. Book excerpt: To humans, cold has a distinctly positive quality. 'Frostbite', 'a nip in the air', 'biting cold', all express the concept of cold as an entity which attacks the body, numbing and damaging it in the process. Probably the richness of descriptive English in this area stems from the early experiences of a group of essentially tropical apes, making their living on a cold and windswept island group half way between the Equator and the Arctic. During a scientific education we soon learn that there is no such thing as cold, only an absence of heat. Cold does not invade us; heat simply deserts. Later still we come to appreciate that temperature is a reflection of kinetic energy, and that the quantity of kinetic energy in a system is determined by the speed of molecular movement. Despite this realization, it is difficult to abandon the sensible prejudices of palaeolithic Homo sapiens shivering in his huts and caves. For example; appreciating that a polar bear is probably as comfortable when swimming from ice floe to ice floe as we are when swimming in the summer Mediterranean is not easy; understanding the thermal sensa tions of a 'cold-blooded' earthworm virtually impossible. We must always be wary of an anthropocentric attitude when considering the effects of cold on other species.

Available in PDF, EPUB and Kindle. Book excerpt: Temperature is one facet in the mosaic of physical and biotic factors that describes the niche of an animal. Ofthe physical factors it is ecologically the most important. for it is a factor that is all-pervasive and one that. in most environments. lacks spatial or temporal constancy. Evolution has produced a wide variety of adaptive strategies and tactics to exploit or deal with this variable environmental factor. The ease with which temperature can be measured. and controlled experimentally. together with its widespread influence on the affairs of animals. has understandably led to a large. dispersed literature. In spite of this no recent book provides a comprehensive treatment of the biology of animals in relation to temperature. Our intention in writing this book was to fill that gap. We hope we have provided a modern statement with a critical synthesis of this diverse field. which will be suitable and stimulating for both advanced undergraduate and post graduate students of biology. This book is emphatically not intended as a monographical review. as thermal biology is such a diverse. developed discipline that it could not be encompassed within the confines of a book of this size.

Available in PDF, EPUB and Kindle. Book excerpt: Whether you're a polar bear giving birth to cubs in an Arctic winter, a camel going days without water in the desert heat, or merely a suburbanite without air conditioning in a heat wave, your comfort and even survival depend on how well you adapt to extreme temperatures. In this entertaining and illuminating book, biopsychologist Mark Blumberg explores the many ways that temperature rules the lives of all animals (including us). He moves from the physical principles that govern the flow of heat in and out of our bodies to the many complex evolutionary devices animals use to exploit those principles for their own benefit. In the process Blumberg tells wonderful stories of evolutionary and scientific ingenuity--how penguins withstand Antarctic winters by huddling together by the thousands, how vulnerable embryos of many species are to extremes of temperature during their development, why people survive hour-long drowning accidents in winter but not in summer, how certain plants generate heat (the skunk cabbage enough to melt snow around it). We also hear of systems gone awry--how desert species given too much water can drink themselves into bloated immobility, why anorexics often complain of feeling cold, and why you can't sleep if the room is too hot or too cold. After reading this book, you'll never look at a thermostat in quite the same way again. Table of Contents: Introduction 1. Temperature: A User's Guide 2. Behave Yourself 3.

Written entertainingly for a popular audience, the book argues that the evolved behaviour and physical characteristics of most creatures, from the tiniest nematode worm to the largest whale, is governed by the need to maintain a comfortable body temperature. --Emma Crichton-Miller, The Telegraph Reviews of this book: Blumberg...presents a thoroughly interesting book on body temperature and its many influences, loaded with a marvelously broad range of topics related to the biology of body temperature. From structural adaptations, such as ear size, circulatory patterns, and body shape that have evolved to help maintain body temperature, to psychological effects of temperature, the physiology of fevers, and even sexual-thermal metaphors used in everyday conversation. A host of fascinating aspects of how species respond to temperature changes are also discussed...Body Heat is great reading, certain to produce an enlightened appreciation for how body temperature control is critical for all organisms. --M. A. Palladino, Choice Reviews of this book: Mark S. Blumberg, in Body Heat, also takes the role of temperature in human affairs onto a global stage, but his metaphors, languages and conclusions are neither biblical nor prophetic. Instead he wants to remind us just how narrow our margins of tolerance are against that ultimate enemy: cold...Blumberg loves his subject, is convinced of its importance, and he wants to put across the intrinsic interest of temperature physiology to a larger audience. He retains a light touch--and because he is an active researcher in his own right, is able to bring new information and new insights to his pages. --Jonathan Kingdon, Times Literary Supplement This book is a real treat. Mark Blumberg takes something we normally hardly think about, and makes it into a fascinating topic, with colorful examples from fields as disparate as etymology and entomology. You probably will be repeating many of the stories he tells to those around you, as you discover why a fever may be good for you, or how babies generate their own heat, or how eating disorders interact with body temperature problems. It's entertaining, interesting, and great fun. --Michael Leon, University of California, Irvine This is an engaging enchilada of a book, wrapping up cold feet, a warm heart, hot sex, and chili peppers, for easy digestion by the general science consumer. Delicious! --Bernd Heinrich, University of Vermont, and author of The Hot-Blooded Insects: Strategies and Mechanisms of Thermoregulation

Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Animal Biology Series is an innovative new series of supplementary undergraduate texts in comparative animal biology. Topics within each book are addressed using examples from throughout the animal kingdom, looking for parallels that transcend taxonomy. Further reading sections will guide the student into the literature at greater depth. The series will be international in scope, both in terms of the species used as examples and in references to scientific work. Energy for Animal Life, the first book in the series, is about how animals get energy, and how they use it, a central topic in our understanding of animal biology. Life depends on energy, and much of the activity of animals is devoted to getting the food which is their energy source. It encompasses the food chain, from solar radiation and photosynthesis to food sources for herbiviores and for carnivores, and compares the merits of different designs of digestive system, and of different strategies for finding and choosing food. Of course, animal energy isn't simply a question of feeding, and several chapters in turn look at energy use. The energy costs of motion - of running, swimming, and flight - are discussed in one chapter, and the energetic demands of growth and reproduction in another. A chapter on body temperature shows how the processes of life go faster at higher temperatures, and discusses how animals regulate their temperature. A final chapter draws all of these aspects of energy use together, and considers the energy budgets of several different animals, assessing the different energy gains and costs of their everyday activities in the wild. The book is truly comparative, drawing on examples from a wide range of animal species, and lots of practical information on relevant experiments is included. The style is very accessible, and suitable as supplementary reading for first and second year undergraduates taking a degree course in biological sciences.

Available in PDF, EPUB and Kindle. Book excerpt: In a time of uncertainty about our environmental future—an eye-opening global tour of some of the most wounded places on earth, and stories of how a passionate group of eco-restorers is leading the way to their revitalization. Award-winning science journalist Judith D. Schwartz takes us first to China’s Loess Plateau, where a landmark project has successfully restored a blighted region the size of Belgium, lifting millions of people out of poverty. She journeys on to Norway, where a young indigenous reindeer herder challenges the most powerful orthodoxies of conservation—and his own government. And in the Middle East, she follows the visionary work of an ambitious young American as he attempts to re-engineer the desert ecosystem, using plants as his most sophisticated technology. Schwartz explores regenerative solutions across a range of landscapes: deserts, grasslands, tropics, tundra, Mediterranean. She also highlights various human landscapes, the legacy of colonialism and industrial agriculture, and the endurance of indigenous knowledge. The Reindeer Chronicles demonstrates how solutions to seemingly intractable problems can come from the unlikeliest of places, and how the restoration of local water, carbon, nutrient, and energy cycles can play a dramatic role in stabilizing the global climate. Ultimately, it reveals how much is in our hands if we can find a way to work together and follow nature’s lead.

Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1 Temperature Regulation in Animals There are, broadly speaking, two kinds of animals with regard to body temperature: exothermic (cold-blooded) and endothermic (warm-blooded) animals. The exothermic animals, such as reptiles, do not supply body heat by metabolic conversion of food to heat. Reptiles allow their surroundings to determine their body temperature. They lie out in the sun to warm their body. If they are too hot, they seek the shade or even burrow into the ground. At night they hide from the cold in burrows or squeeze into cracks between rocks or hide in leaf cover. Reptiles avoid the extremes of temperature. When reptiles become cool, their movements slow down, and chemical processes in their bodies, such as digestion, are inhibited. Predators, such as hawks and eagles, find it easier to prey on lizards and snakes in cooler weather. The distribution of reptiles is somewhat limited by their exothermic character. They do not thrive in cold climates1. What are the advantages and disadvantages in being exothermic? When the lizard is in a cool environment and cannot find a warmer spot, its body simply cools to the temperature of the surroundings. It is not necessary for the exothermic lizard to generate heat to increase its body temperature. This means that the lizard uses less energy and does not have to eat as much. As the lizard cools its digestion, breathing rate and heart rate slow, saving energy. A disadvantage occurs when the cool lizard is attacked by a predator. If warm, he could run fast and have a much better chance of 1 St. Patrick did not chase the snakes out of Ireland. Ireland was already completely free of snakes. St. Patrick was instrumental in converting pagans to Christianity. Since the snake was a symbol used in pagan rituals, St. Patrick was influential in ridding Ireland of the ritual use of symbolic snakes. 10 Verne A. Simon evading capture. A warm lizard being chased by a predator can move quite fast for a short distance, but like other exotherms, lacks endurance and soon tires. When the exotherm is running fast, its effort is anaerobic, that is, is not using oxygen, and lactic acid is building up in its body. It soon tires and is unable to exert itself. It must recover by taking in oxygen to rid the body of lactic acid. Another disadvantage of exothermic life is that cold climates are not available as habitat. If there is a sudden climate change, an exothermic animal wouldn't be able to mount the sustained effort needed to migrate to a better environment. The exothermic creature might simply perish. About 180 million years ago, mammals appeared. Mammals are endothermic (warm-blooded) and are able to maintain a nearly constant body temperature regardless of the temperature of their surroundings within wide limits. Their bodies will not tolerate too high or too low a temperature. If the surroundings are too hot or cold, causing the body temperature to exceed allowed limits, the animal will die. Mammals have furry coats to help them tolerate low temperatures. Sea-dwelling mammals-whales, seals, and walrus-have thick layers of blubber for insulation. Birds are endothermic and have feathers to protect them from the cold. Many types of birds and mammals survive in cold climates. Emperor penguins even live in the Antarctic, in the coldest climate on earth. Under normal circumstances, mammals and birds manage to keep this very nearly constant body temperature regardless of the temperature of their surroundings. Mammals are characterized by having body hair and suckling their young. This latter behavior gives the class its name; mammals must have mammary glands. A second advantage is that endothermic animals are not limited to activity only in daylight hours. In many locat

This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do mammals manage to maintain their body temperature within the same narrow range in environments as different as polar regions and hot deserts? This advanced text describes the morphological features and physiological mechanisms by which humans and other mammals maintain their body temperature within a narrow range despite large variations in climatic conditions and internal heat production. Its 19 chapters deal with the physics of heat exchange with the environment, and the autonomic and behavioural mechanisms available to control the loss and production of heat. The neuronal basis of temperature regulation and current concepts of the central nervous interface between temperature signals generated in the body and control mechanisms are examined in detail. This book is of invaluable help for undergraduates, postgraduates, teachers, physicians and scientists.

Download or read book Climate Change Impact on Livestock Adaptation and Mitigation written by Veerasamy Sejian and published by Springer. This book was released on 2015-03-31 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses in detail both livestock’s role in climate change and the impacts of climate change on livestock production and reproduction. Apart from these cardinal principles of climate change and livestock production, this volume also examines the various strategies used to mitigate livestock-related GHG emissions, and those which can reduce the impacts of climate change on livestock production and reproduction. Presenting information and case studies collected and analyzed by professionals working in diversified ecological zones, the book explores the influence of climate change on livestock production across the globe. The most significant feature of this book is that it addresses in detail the different adaptation strategies and identifies targets for different stakeholders in connection with climate change and livestock production. Further, it puts forward development plans that will allow the livestock industries to cope with current climate changes and strategies that will mitigate the effects by 2025. Lastly, it provides researchers and policymakers several researchable priorities to help develop economically viable solutions for livestock production with less GHG emissions, promoting a cleaner environment in which human beings and livestock can live in harmony without adverse effects on productivity. Given that livestock production systems are sensitive to climate change and at the same are themselves a contributor to the phenomenon, climate change has the potential to pose an increasingly formidable challenge to the development of the livestock sector. However, there is a dearth of scientific information on adapting livestock production to the changing climate; as such, well-founded reference material on sustaining livestock production systems under the changing climate scenarios in different agro-ecological zones of the world is essential. By methodically and extensively addressing all aspects of climate change and livestock production, this volume offers a valuable tool for understanding the hidden intricacies of climatic stress and its influence on livestock production.
