Available in PDF, EPUB and Kindle. Book excerpt: Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals—the most energy-intensive fauna on the planet—must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures. Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates—much of our own energy is spent maintaining our 98.6?F temperature—and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environments, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.

Available in PDF, EPUB and Kindle. Book excerpt: Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.

Download or read book Semi aquatic Mammals written by Glynnis A. Hood and published by JHU Press. This book was released on 2020-10-13 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking review of the seldom-studied semi-aquatic freshwater mammals, covering biology, behavior, and conservation. Semi-aquatic mammals are some of the rarest and most endangered mammals on earth. What binds them together in the minds of biologists, despite their diverse taxa and body forms, are evolutionary traits that allow them to succeed in two worlds—spending some time on land and some in the water. Semi-aquatic Mammals fills a crucial void in the literature by highlighting the important ecological roles and curious biology of these remarkable animals. In this unique book, wildlife ecologist Glynnis A. Hood presents the first comprehensive examination of a global suite of 140 freshwater semi-aquatic mammals. Each one has overcome the distinct ecological challenges of thriving in both aquatic and terrestrial habitats as part of everyday life. Covering millions of years, Hood's exploration begins with the extinct otter-like Buxolestes and extends to consider the geographical, physical, behavioral, and reproductive traits of its present-day counterparts. Hood explains how semi-aquatic mammals are able to navigate a viscous environment with almost no resistance to heat loss, reveals how they maintain the physical skills necessary to avoid predation and counter a more thermally changeable environment, and describes the array of adaptations that facilitate success in their multifaceted habitats. She also addresses specific conservation challenges faced by these mammals. Her analysis takes readers to the haunts of intriguing semi-aquatic mammals from around the world, • introducing the "paradoxical platypus," an Australian egg-laying monotreme that detects prey through electroreception • venturing into the swamps and mangroves of Southeast Asia, where fishing cats wave their paws above the water's surface to lure prey • trawling the streams and lakes of South America, where the female water opossum uses its backward-facing pouch to keep her babies warm during deep dives • spending time with species that engineer freshwater habitats into more productive and complex systems, including North American beavers and Africa's common hippopotamus Featuring award-winning artist Meaghan Brierley's stunning illustrations throughout, Semi-aquatic Mammals is an unparalleled reference on some of the world's most tenacious and fascinating mammals.

Download or read book Reproductive Energetics in Mammals written by Andrew S. I. Loudon and published by Oxford University Press, USA. This book was released on 1987 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the proceedings of a symposium which brought together biologists from diverse backgrounds to review the current research on reproductive energetics. Agricultural scientists and ecologists have long been interested in the flow of energy through populations so that the ultimate constraints to production can be identified. However, the study of the ecology of wild mammals will not proceed effectively until scientists are able to obtain reliable data on the energy costs of pregnancy and lactation in the breeding female, and relate these in turn to the food supply, and the survival and growth of offspring. The work presented here is likely to attract serious research interest from ecologists, reproductive biologists, physiologists, and zoologists from some time to come.

Download or read book Animal Energetics written by Alan E. Brafield and published by Springer. This book was released on 2012-12-27 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: All animals, from protozoans to primates, utilize energy in every aspect of their lives. Metabolic processes transform energy within the living cells. Individual animals obtain energy with their food and use it in a variety of ways. Populations and communities pass energy through their ecosystem. The growing interest in animal energetics is therefore seen in three major areas of zoology-biochemistry, physiology and ecology. We have tried to describe the main features of almost all these aspects, with the aim of arousing or feeding an interest in energetics in general as well as supplying some information on particular parts of the subject. The substantial list of references is intended to guide the reader to larger or more specialized works. In covering such a wide field in so small a compass we will have been guilty of over-generalizations, but we find when teaching energetics, whether physiological or ecological, that students easily lose sight of the principles if all statements are hedged about with every relevant condition and exception. We have drawn examples from a wide range of animals, avoiding over-emphasis on mammals, but we have tended to favour those groups with which we are more familiar. We are grateful to many people for helpful discussions and in particular to Kenneth Denbigh, Derek Miller and John Stirling for valuable criticisms of parts of the manuscript. We are responsible for all remaining errors, of course, and will welcome having them drawn to our notice. A.E.B. M.J.L.

Download or read book Ecological and Environmental Physiology of Mammals written by Philip C. Withers and published by Oxford University Press. This book was released on 2016-10-27 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammals are the so-called "pinnacle" group of vertebrates, successfully colonising virtually all terrestrial environments as well as the air (bats) and sea (especially pinnipeds and cetaceans). How mammals function and survive in these diverse environments has long fascinated mammologists, comparative physiologists and ecologists. Ecological and Environmental Physiology of Mammals explores the physiological mechanisms and evolutionary necessities that have made the spectacular adaptation of mammals possible. It summarises our current knowledge of the complex and sophisticated physiological approaches that mammals have for survival in a wide variety of ecological and environmental contexts: terrestrial, aerial, and aquatic. The authors have a strong comparative and quantitative focus in their broad approach to exploring mammal ecophysiology. As with other books in the Ecological and Environmental Physiology Series, the emphasis is on the unique physiological characteristics of mammals, their adaptations to extreme environments, and current experimental techniques and future research directions are also considered. This accessible text is suitable for graduate level students and researchers in the fields of mammalian comparative physiology and physiological ecology, including specialist courses in mammal ecology. It will also be of value and use to the many professional mammologists requiring a concise overview of the topic.

Download or read book Avian Energetics and Nutritional Ecology written by C. Carey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A symposium held in 1973 chaired and organized by William R. Dawson was the first major attempt to summarize and synthesize the existing information in the then emerging field of avian energetics. The symposium featured papers by James R. King, William A. Calder III, Vance A. Tucker, and Robert E. Ricklefs and com mentaries by George A. Bartholomew, S. Charles Kendeigh, and Eugene P. Odum. The proceedings of the symposium, Avian Energetics (Paynter 1974), played a critical role in stimulating interest and research in the field of avian energetics. Some twenty-odd years later, we are making another attempt to summarize the information in the field of avian energetics. Some obvious differences exist be tween its predecessor and this volume. Numerous improvements in methodology, such as the use of doubly labeled water to estimate metabolism in free-living birds, now allow researchers to ask questions that could not be addressed previ ously. Second, consideration of nutrition is now inseparable from that of energet ics. This merger is necessary not only because food intake is the source of both en ergy and nutrients but also because one or more nutrients, rather than energy, can be limiting for a given species in a particular instance. Finally, the study of ener getics and nutritional ecology, particularly in birds and mammals, has grown so dramatically that a single volume can now only partially cover the range of possi ble topics and can catalogue only a sampling of all the studies on the subject.

Download or read book Ecophysiology of Small Desert Mammals written by Allan A. Degen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since small mammals have a large surface to mass ratio, one would expect them to quickly dehydrate and perish at high environmental temperatures. Nonetheless, a large number of small mammal species inhabit deserts. This fascinating phenomenon is investigated by Prof. A. Allan Degen in his book. The majority of small desert mammals are rodents, but shrews of several grams and small foxes of 1 kg are also present. Their survival is due mainly to behavioural adaptations and habitat selection, however, physiological adaptations also contribute to the success. Interestingly, many small mammals that live in different deserts of the world show similarities in their adaptive traits although they have different taxonomic affinities.
