This book was released on 2018-09-14 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolic rate is a key ecophysiological factor determining fitness, distribution, survival and reproductive strategies of organisms. The ability to endogenously produce heat and elevate body temperature beyond ambient, has far reaching ecological implications. The diversity of thermogenic mechanisms and strategies employed throughout the animal kingdom is truly phenomenal and one of the greatest biological mysteries. Interestingly, even heat producing plants have been characterised. Over the last several decades, the oversimplified distinction between warm- and cold blooded animals has well and truly been put to rest and the terms “endo- and ectotherm” have been established. Birds and mammals are regarded as endotherms, capable of maintaining high body temperatures within highly precise boundaries. On contrary, in ectothermic organisms ambient temperature governs body temperature and metabolism, encompassing the majority of present day species. However, it has recently become very clear that this distinction is still not accurate enough to describe the vastness of heat generating mechanisms within endo- but also ectotherms. Indeed, a plethora of ectothermic animals display endogenous as well as behavioural means of temperature control and mechanisms for heat generation. There is large diversity in regards to thermoregulatory ability and strategy within endotherms as well, with some groups being classified by separate categories such as basoendotherms and mesotherms. Considerable interest and efforts has been put into the quest to understand the underlying physiological mechanisms leading and facilitating high metabolic rates and body temperatures of endotherms. These mechanisms are far from being exhaustively studied and the evolutionary trajectory leading to high metabolic rates and stable body temperatures is equally, vividly debated. This discussion includes an array of questions and theories surrounding the presence of endothermy in extinct dinosaurs. In addition, a lively debate surrounds the evolutionary drivers promoting the establishment of endothermy with clear support of direct or indirect selective benefits. Within this Research Topic we plan to compile the latest ideas, knowledge and experimental work to elucidate the patterns of the evolution of endothermy and its transition/distinction from ectothermy. The focus is on key physiological mechanisms supporting this transition and contributing to the maintenance of high metabolic rates and body temperature in endotherms, as well as mechanisms for local heterothermy and heat dissipation in ectotherms. These mechanisms and conclusions may be derived from different levels of organisation such as population, taxon, species as well as tissue, cellular or molecular levels. It may also encompass novel experimental or theoretical models testing evolutionary theories of endothermy. A comparative approach is encouraged but not fundamental.

Available in PDF, EPUB and Kindle. Book excerpt: Birds and dinosaurs have dominated human interest for decades. In this well-supported revolutionary view of the field, critical questions are explored with credible evidence and biological thought. Are birds derived directly from advanced dinosaurs, or are they closely related dinosaur cousins? Did flight originate via the natural "gravity-assisted" trees-down model, or from the improbable “gravity-resisted” ground-up model? Were the earliest birds ground-predators or trunk-climbing gliders? Were dinosaurs hot-blooded with insulating protofeathers, or highly active, cold-blooded reptiles? These are among the questions addressed in this path-breaking book. Current consensus suggests that early birds were earth-bound and flight began on the ground. Reversing that logic, since birds are hot-blooded, by inference so too were dinosaurs, and extraordinarily complex feathers, flight brain and inner ear, evolved before flight in dinosaurs. The iconic early bird Archaeopteryx, despite innumerable flight and arboreal features, is now displayed as an earth-bound predator that could not fly. In reality, we have yet to provide satisfactory explanations for much of the biological origin and early evolution of birds. Among the questions addressed is whether truly feathered dinosaurs are in reality lost or "hidden birds?" The architectural complexity of feathers leads the author to the conclusion that if an animal has evolved extraordinarily complex, aerodynamically-designed feathers, an avian flight hand, flight membranes, and a flight brain, it's a bird. Birds and dinosaurs captivate and enchant the human imagination. These intriguing animals have dominated the field of paleontology and evolution for the past half century, engendering heated debate on avian ancestry, the origin of flight and feathers, and the biology of their fossils. Are birds living dinosaurs? In this series of entertainingly contentious and captivating essays evolutionary biologist Alan Feduccia writes with verve and humor to expose major problems in the field and advocate liberation from the shackles of consensus thinking about birds and dinosaurs. He maintains that the euphoria of paleontologists claiming to have solved the major problems of bird evolution is premature, largely generated by the adoption of a rigid, cult-like methodology, heavily blended with ideology, and excluding many biological and geological principles. He adroitly exposes and elucidates major mistakes in the field and their aftermath. Romancing the Birds and Dinosaurs is a lucid revelation of clarity and synthesis, a fascinating unveiling of the underlying science that has produced the good, but also often appalling fossil research and wild speculation in bird and dinosaur evolution. A must read for anyone interested in this rapidly evolving field, the short, concise and incisive essays provide the reader with access to this complex topic. REVIEWS and WORDS OF PRAISE In this strikingly unconventional and brilliant book, Professor Alan Feduccia presents the current status of the recent controversy about the origin of birds with clarity and vigor. A thought-provoking personal exploration of what the bird fossils represent. ---Sankar Chatterjee, Paul Whitfield Horn Distinguished Professor of Geosciences and Curator of Paleontology, Texas Tech University. Feduccia's book eloquently reminds us that consensus science is to be shied away from especially when it is used to plead special cases against basic scientific principles. The concept of “lost birds” is particularly intriguing as it defines what birds are and how special science obfuscates the simplicity of evolution. ---David A. Burnham, Associate Researcher, University of Kansas Biodiversity Institute and Natural History Museum. Based on a thorough understanding of the empirical evidence, Feduccia presents a convincing account of avian origins from their putative ancestors. ---Walter J. Bock, Professor of Evolutionary Biology, Columbia University and Research Associate, American Museum of Natural History. With candor, clear thinking, humor, and abundant evidence, Alan Feduccia’s Romancing the Birds and Dinosaurs should be mandatory reading for the countless millions who are intrigued by dinosaurs and their relatives, the birds. Feduccia points out the many empirical and logical shortcomings in the stubborn majority view that birds evolved from dinosaurs, an idea now solidly entrenched as dogma in education and popular culture. This new book will be as interesting to those who study human behavior and scientific methods as it will to students of vertebrate evolution. ---David W. Steadman, Curator of Ornithology, Professor of Biology, Florida Museum of Natural History, University of Florida.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first re-appraisal in 50 years of concepts of development made in birds. This book is a case study in evolutionary diversification of life histories. Although birds have a rather uniform body plan and physiology, they exhibit marked variation in development type, parental care, and rate of growth. Altricial birds are fully dependent on their parents for warmth and nutrition and begin posthatching life in a more or less embryonic condition. At the other extreme, such superprecocial species as the megapodes are independent of all parental care from hatching, and the neonate, able to fly, resembles an adult bird. This book thus attempts to present an integrative perspective of organism biology, ecology, and evolution.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental temperature varies in time and space on timescales ranging from a few hours to long-term climate change. Organisms are therefore continually challenged to regulate and maintain functional capacities as their thermal environment changes. This volume brings together many of the leading workers in thermal biology, with backgrounds spanning the disciplines of molecular biology, cell biology, physiology, zoology, ecology and evolutionary biology, to discuss the responses of a wide range of species to temperature change at all scales of organization, ranging through the molecular, cellular, organismal, population and ecosystem levels. The volume provides an important and comprehensive contribution to the study of temperature adaptation, which, given the concern about global climate change, will provide much to interest a wide range of biologists.

Book excerpt: How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields—work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms—we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines—from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology—the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of thermoregulation in endotherms has contributed much to the emergence of the concept of control theory in biology. By the same token, the study of tempera ture adjustment in ectotherms is likely to have a far-reaching influence on ideas on the regulation of metabolism in general. The reason for this is that ectotherms, in adapting to the vagaries of a thermally unstable environment, deploy a range of subtle molecular and organismic strategies. Thus the experimenter, using temperature changes as a tool, is well equipped to analyze some of these strategies. This approach has enabled some important mechanisms of temperature-induced adaptation to be elucidated; the most striking of these are the effects on metabolism of changes in the conformation of enzymes and the transfer properties of membranes. Furthermore, there is a vague but persistent feeling among those working in this field that changes in the nervous system will ultimately prove to be the agency by which many of the molecular mechanisms of temperature adaptation are controlled. Should this indeed be the case, a new phase would soon begin in our understanding of the interactions between the systemic and the cellular levels of organization. However, it is not only questions about the causes of temperature adaptation that can provide answers of potential importance to the general biologist; of equal significance are questions as to the meaning of temperature adaptation in a particular organism.

This book was released on 2012-12-06 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: To scientists engaged in research on the cellular mechanisms in the mammalian brain, concepts of "motivation" seem to be a logical neces sity, even if they are not fashionable. Immersed in the detailed, time consuming research required to deal with mammalian nerve cells, we usually pay scant attention to the more global brain -behavior questions that have arisen from decades of biological and psychological studies. We felt it was time to confront these issues-namely, how far has neuro biological investigation come in uncovering mechanisms by which moti vational signals influence behavior? At Rockefeller University, we have recently held a course on this subject. We restricted our treatment to those motivational systems most tractable to physiological approaches, and invited scientists skilled in both behavioral issues and physiological techniques to participate. This volume results from that course. The deans and administration at Rockefeller University provided much help in planning the course, and the staff of Springer-Verlag assisted in planning the book. Gabriele Zummer helped organize both the course and the processing of book chapters. They all deserve our thanks. December 1981 Donald W.

Available in PDF, EPUB and Kindle. Book excerpt: Though physiological ecology has been a discipline since the 1950s, McNab redresses a perceived absence of a theoretical framework with a comparative, inductive approach to studying vertebrate evolution and ecology. He discusses the patterns and limits of adaptation to the environment, acclimation to temperature variation and material exchange with the environment, and the energetics of locomotion and growth. The final section treats the significance of energetics for population ecology and distribution. Includes a taxonomic as well as subject index. Suitable for advanced students and researchers in the biological and ecological sciences. The Gainesville, FL-based author is referred to by the foreword writer as a keen naturalist, but his credentials are not stated. Annotation copyrighted by Book News Inc., Portland, OR.
