Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2010 Lane Anderson Award Drawing on breakthrough research in evolution, genetics, and on their extensive work in the field and lab, wildlife biologists John and Mary Theberge explain for non-scientists the real facts of life. Birds that suddenly grow gall bladders, when their species has none. Moose with antlers so big they encumber their movement through the forest. Butterflies that risk extinction by overwintering en masse. These are just a few stories the Theberges tell in their examination of what the mechanisms of evolution are and how they work. With examples from the very latest discoveries in genetics and ones they have made in their own field work, The Ptarmigan's Dilemma is a ground-breaking explanation of evolution for non-scientists. By marrying the separate sciences of ecology and genetics, the Theberges paint a picture far richer than either discipline can alone of how, for almost 4 billion years, life on Earth has evolved into the rich diversity that's under threat today. Along the way, they explain just what "the survival of the fittest" really means, how dramatic evolutionary changes can take place in just one generation, and how our too-little knowledge of or interest in how life on Earth organizes and supports itself is rapidly making us a danger to ourselves.

Download or read book Birds and Us written by Tim Birkhead and published by Princeton University Press. This book was released on 2022-08-09 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: From award-winning author and ornithologist Tim Birkhead, a sweeping history of the long and close relationship between birds and humans Since the dawn of human history, birds have stirred our imagination, inspiring and challenging our ideas about science, faith, art, and philosophy. We have worshipped birds as gods, hunted them for sustenance, adorned ourselves with their feathers, studied their wings to engineer flight, and, more recently, attempted to protect them. In Birds and Us, award-winning writer and ornithologist Tim Birkhead takes us on a dazzling epic journey through our mutual history with birds, from the ibises mummified and deified by Ancient Egyptians to the Renaissance fascination with woodpecker anatomy—and from the Victorian obsession with egg collecting to today’s fight to save endangered species and restore their habitats. Spanning continents and millennia, Birds and Us chronicles the beginnings of a written history of birds in ancient Greece and Rome, the obsession with falconry in the Middle Ages, and the development of ornithological science. Moving to the twentieth century, the book tells the story of the emergence of birdwatching and the field study of birds, and how they triggered an extraordinary flowering of knowledge and empathy for birds, eventually leading to today’s massive worldwide interest in birds—and the realization of the urgent need to save them. Weaving in stories from Birkhead’s life as scientist, including far-flung expeditions to wondrous Neolithic caves in Spain and the bustling guillemot colonies of the Faroe Islands, this rich and fascinating book is an unforgettable account of how birds have shaped us, and how we have shaped them.

Download or read book Canadian Inland Seas written by I.P. Martini and published by Elsevier. This book was released on 2011-09-22 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various chapters of this book have been written by researchers who are still working in the Canadian Inland Seas region. The chapters synthesize what is known about these seas, yet much still is to be learnt. It is hoped that this collection of information will serve as a springboard for future, much needed, studies in this fascinating, diverse region, and will stimulate comparative analyses with other subarctic and arctic basins of the world. The Canadian Inland Seas are the only remnants, albeit cold, of the ancient cratonic marine basins which occupied central North America throughout the Paleozoic and part of the Mesozoic. Precambrian rocks and gently dipping Paleozoic sedimentary rocks underlie the seas. The area is also close to the centers of Pleistocene glaciations. The coastal areas represent an emerged landscape of the post-glacial Tyrrell sea, as the region has been isostatically uplifted to about 350 meters since glacial times. A total of 56 fish species inhabit Hudson Bay and James Bay. Seals, whales and one of the largest and southernmost populations of polar bears inhabit the seas as well. The coastal areas are important habitats for migratory bird populations, some of which migrate from as far away as Southern Argentina. The ostic environment has preserved these regions relatively unchanged by man, with only a major harbour at Churchill, Manitoba, which is active for part of the year, and a second large, rail-terminal settlement in the south at Moosonee, Ontario. A few, small, native Indian and Inuit villages dot the coasts. The seas are being affected indirectly by the damming of rivers for the generation of hydroelectric power, and by drainage diversions towards the man-made reservoirs. A major project is being completed in Quebec east of James Bay, but other rivers in Ontario and Manitoba have been dammed as well. Undoubtedly freshwater is one of the more important resources of the area, however its exploitation needs careful thought because of the possible long-range effects on the environment, particularly the coastal marshes, which sustain much of the eastern American intercontinental migratory avifauna. Other resources occur in the regions, primarily minerals and perhaps petroleum. For the most part however, such resources remain to be discovered.
