Body Size in Mammalian Paleobiology - Estimation and Biological Implications (Hardcover, New): John Damuth, Bruce J. MacFadden Body Size in Mammalian Paleobiology - Estimation and Biological Implications (Hardcover, New)
John Damuth, Bruce J. MacFadden
R3,579 Discovery Miles 35 790 Ships in 12 - 17 working days

This valuable collection of essays presents and evaluates techniques of body-mass estimation and reviews current and potential applications of body-size estimates in paleobiology. Papers discuss explicitly the errors and biases of various regression techniques and predictor variables, and the identification of functionally similar groups of species for improving the accuracy of estimates. At the same time other chapters review and discuss the physiological, ecological, and behavioral correlates of body size in extant mammals; the significance of body-mass distributions in mammalian faunas; and the ecology and evolution of body size in particular paleofaunas. Coverage is particularly detailed for carnivores, primates, and ungulates, but information is also presented on marsupials, rodents, and proboscideans.

The mystery of how migrating animals find their way over unfamiliar terrain has intrigued people for centuries, and has been the focus of productive research in the biological sci ences for several decades. Whether or not the earth's magnetic field had anything to do with their navigational abilities has sufaced and been dismissed several times, beginning at least in the mid to late 1800s. This topic generally remained out of the mainstream of scientific research for two reasons: (1) The apparent irreproducibility of many of the be havioral experiments which were supposed to demonstrate the existence of the magnetic sense; and (2) Perceived theoretical difficulties which were encountered when biophysi cists tried to understand how such a sensory system might operate. However, during the mid to late 1960s as the science of ethology (animal behavior) grew, it became clear from studies on bees and birds that the geomagnetic field is used under a variety of conditions. As more and more organisms were found to have similar abilities, the problem shifted back to the question as to the basis of this perception. Of the various schemes for trans ducing the geomagnetic field to the nervous system which have been proposed, the hy pothesis of magnetite-based magnetoreception discussed at length in this volume has per haps the best potential for explaining a wide range of these effects, even though this link is as yet clear only in the case of magnetotactic bacteria."

Broader Impacts of Science on Society (Paperback): Bruce J. MacFadden Broader Impacts of Science on Society (Paperback)
Bruce J. MacFadden
R757 Discovery Miles 7 570 Ships in 12 - 17 working days

How do scientists impact society in the twenty-first century? Many scientists are increasingly interested in the impact that their research will have on the public. Scientists likewise must answer the question above when applying for funding from government agencies, particularly as part of the 'Broader Impacts' criterion of proposals to the US National Science Foundation. This book equips scientists in all disciplines to do just that, by providing an overview of the origins, history, rationale, examples, and case studies of broader impacts, primarily drawn from the author's experiences over the past five decades. Beyond including theory and evidence, it serves as a 'how to' guide for best practices for scientists. Although this book primarily uses examples from the NSF, the themes and best practices are applicable to scientists and applications around the world where funding also requires impacts and activities that benefit society.

R1,544 Discovery Miles 15 440 Ships in 12 - 17 working days

There is a growing interest in the biological implications of body size in animals. This parameter is now being used to make inferences and predictions about not only the habits and habitat of a particular species, but also as a way to understand patterns and biases in the fossil record. This valuable collection of essays presents and evaluates techniques of body-mass estimation and reviews current and potential applications of body-size estimates in paleobiology. Coverage is particularly detailed for carnivores, primates and ungulates, but information is also presented on marsupials, rodents and proboscideans. Body Size in Mammalian Paleobiology will prove useful to researchers and graduate students in paleontology, mammalogy, ecology and evolution programmes. It is designed to be both a practical handbook for researchers making and using body-size estimates, and a sourcebook of ideas for applying body size to paleontological problems and directions for future research.

Fossil Horses - Systematics, Paleobiology, and Evolution of the Family Equidae (Paperback, New Ed): Bruce J. MacFadden Fossil Horses - Systematics, Paleobiology, and Evolution of the Family Equidae (Paperback, New Ed)
Bruce J. MacFadden
R2,081 Discovery Miles 20 810 Ships in 12 - 17 working days

The family Equidae have an extensive fossil record spanning the past 58 million years, and the evolution of the horse has frequently been used as a classic example of long-term evolution. In recent years, however, there have been many important discoveries of fossil horses, and these, in conjunction with such new methods as cladistics, and techniques such as precise geochronology, have allowed us to achieve a much greater understanding of the evolution and biology of this important group. This book synthesizes the large body of data and research relevant to an understanding of fossil horses from several disciplines including biology, geology and paleontology. Using horses as the central theme, the author weaves together in the text such topics as modern geochronology, paleobiogeography, climate change, evolution and extinction, functional morphology, and population biology during the Cenozoic period. This book will be exciting reading for researchers and graduate students in vertebrate paleontology, evolution, and zoology.
