Available in PDF, EPUB and Kindle. Book excerpt: After travel through Alaska during the Second World War, in 1947 I went to Barrow with a very lively group of biologists. From their productive research developed the Arctic Research Laboratory. While we examined the rather surpris ingly modest metabolic rates of arctic warmblooded animals in cold, PER SCHO LANDER proposed and then carried out measurements of metabolism of some tropi cal animals in Panama. The differences could be formulated to show the basis of adaptation to arctic cold and to tropical warmth. Imagination and logic were required to formulate the comparison so that it could become a part of science, but the essential measurements were derived from animals and plants in their own arctic and tropical environments. Characteristics that adapt the forms of life to climatic conditions of various environments appear clear in the large dimensions of extremely differing climates. At the time of my arrival in Alaska many of the arctic Eskimos were still largely dependent on natural resources of their immediate and local environment, in which great seasonal changes in temperature and solar radiation appeared as dominant factors. The living environment on which they subsisted was also mar kedly affected by the changes of the seasons, in particular by the change in state of water to ice that terminated summer and by the melting that brought the late transition from winter to summer.

Download or read book Polar Research written by Mary A. Mcwhinnie and published by Routledge. This book was released on 2019-07-16 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highlighting twenty years of U.S. scientific research conducted since the International Geophysical Year (IGY) of 1957-58, this volume marks a turning point in the history of polar investigations and provides a lucid summary of the contributions of many distinguished scientists. The authors provide an overview of major polar research programs, past and present; explore concepts derived, from highly interrelated aspects of physical and life sciences; and seek to offer a glimpse of future polar science and polar development. The introduction briefly describes major physical, biological, and interdisciplinary research programs, as well as the magnitude, extent, and international character of contemporary polar science. Twenty years of polar biological investigations are then reviewed, and subsequent chapters address principles and advances in meteorology, physical oceanography, glaciology, and the geological evidence that hears on the origin of Antarctica. These physical sciences delineate a matrix for the polar biospheres and provide a background for understanding the major categories of structure and dynamic functioning of the marine ecosystem, polar marine mammals, adaptational physiology, and terrestrial biotic adaptations.
Download or read book Alaska Dinosaurs written by Anthony R. Fiorillo and published by CRC Press. This book was released on 2018-01-02 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.

Book excerpt: Snow has had an astonishing influence on the shape of the land and human history. Ruth Kirk writes perceptively of how animals and people survive in the snow; of glaciers, continental ice sheets, blizzards, and avalanches; and of the awesome hazards of Arctic and Antarctic exploration. She discusses both our battles against snow and our uses of it, showing its importance to agriculture, climate, and the future. Through scientific reports and interviews with experts in various fields--from Antarctic explorers to atmospheric physicists--Kirk surveys the scope of snow's influence.

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 The Health Consequences of Modernisation written by Roy J. Shephard and published by Cambridge University Press. This book was released on 1996-02-23 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the health consequences of a transition from an active 'hunter-gatherer' lifestyle to that of sedentary modern living? In this book, the impact of 'modernization' is assessed in various populations in the circumpolar regions. The hazards of living in polar regions, and the adaptations shown culturally, behaviourally and physically by the indigenous peoples are examined and the effect of changes in habitual activity, diet, and general lifestyle due to more urban living patterns on the body composition, pulmonary function and susceptibility to disease discussed. The implications of this switch are important not only for all those concerned about the survival of indigenous communities around the world, but for all of us living in an increasingly sedentary, urban environment. Anthropologists, physiologists and those interested in population fitness will find this a comprehensive and valuable volume.

This book was released on 2004-09-17 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rich detail and vivid anecdotes of adventure....A treasure trove of exotic fact and hard thinking." —New York Times Book Review For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above—so far above that we are in danger of forgetting that we even belong to an ecosystem. Casting his expert eye over the rapidly diminishing areas of wilderness where predators still reign, the award-winning author of The Song of the Dodo and The Tangled Tree examines the fate of lions in India's Gir forest, of saltwater crocodiles in northern Australia, of brown bears in the mountains of Romania, and of Siberian tigers in the Russian Far East. In the poignant and troublesome ferocity of these embattled creatures, we recognize something primeval deep within us, something in danger of vanishing forever.

Download or read book The Reproductive Biology of the Chelonia written by Gerald Kuchling and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comparative view of chelonian reproduction and discusses ecophysiological implications for their captive breeding. Chelonians, with their protective rigid armour, are a phylogenetically antique group of reptiles which radiated to occupy niches from the open waters of the oceans, to rivers, creeks, swamps, forests, savannahs, and deserts. A few North American turtle species have been well studied, but until recently reproductive data on other chelonian species have been scarce. The way in which chelonians adjust their conservative mode of reproduction to the various requirements of their habitats and life styles is the theme of this book; the physiology of reproduction and its interplay with ecological conditions are its central subjects.
Download or read book Wildlife Feeding and Nutrition written by Charles T. Robbins and published by Elsevier. This book was released on 2013-09-03 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife Feeding and Nutrition fills a serious gap in the wildlife and animal nutrition literature by providing a discussion of the basic principles of nutrition and their application to the broader field of wildlife ecology. This book is based on lectures presented in an upper-level wildlife nutrition course taught at Washington State University. The book opens with an introductory chapter on wildlife nutrition. This is followed by separate chapters on general nutrient and energy requirements; protein, water, vitamin, and mineral requirements; impact of nutrition on reproductive characteristics; gastrointestinal anatomy and function; and digestion and nutrient metabolism. The text will be invaluable to wildlife biologists, to those who are interested in captive animal nutrition and management, and to those who are interested in improving the feed supply and nutrition of free-ranging wildlife. It should also be helpful to undergraduate and graduate students as well as teachers of biology and wildlife management. The book will be a useful reference for all who are interested and concerned with wildlife throughout the world.
Download or read book Cold written by Bill Streever and published by Little, Brown. This book was released on 2009-07-22 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: From avalanches to glaciers, from seals to snowflakes, and from Shackleton's expedition to The Year Without Summer, Bill Streever journeys through history, myth, geography, and ecology in a year-long search for cold -- real, icy, 40-below cold. In July he finds it while taking a dip in a 35-degree Arctic swimming hole; in September while excavating our planet's ancient and not so ancient ice ages; and in October while exploring hibernation habits in animals, from humans to wood frogs to bears. A scientist whose passion for cold runs red hot, Streever is a wondrous guide: he conjures woolly mammoth carcasses and the ice-age Clovis tribe from melting glaciers, and he evokes blizzards so wild readers may freeze -- limb by vicarious limb.
