Download or read book The Auks written by Anthony J. Gaston and published by Oxford University Press, USA. This book was released on 1998 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auks are marine birds widespread in the cooler parts of northern seas. Often regarded as the northern hemisphere's counterparts to penguins, they are accomplished underwater swimmers, able to dive to great depths. Among bird families, they exhibit an unusual degree of variability in their breeding sites, which range from old-growth, temperate forests to barren sea-cliffs and rocky outcrops among mountain glaciers. Chick development is equally variable: in some species chicks leave for the sea soon after hatching, while in others they grow to full size at the nest site. This diversity of behavior makes the auks an excellent subject for the study of adaptation. The authors, who have extensive field experience with auks, provide descriptions of the major features of the family and an engaging discussion of the adaptive significance of various traits. Part I contains general chapters on auk evolution, ecology, behavior, chick development, populations, and conservation. These chapters are illustrated with black-and-white drawings, summary graphs and tables. Part II follows with the twenty-three species accounts, giving comprehensive information on the birds in their natural state, including distribution maps. All species are illustrated in color, in superb plates by Ian Lewington especially commissioned for this volume. The Auks is part of Oxford's multi-volume Bird Families of the World, a new series of handbooks for professional scientists and amateur ornithologists. Each volume gives a comprehensive synthesis of current knowledge on one bird family or several related families; the complete series will be the definitive source for information on species of birds.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Alcidae, or auks, are one of the most abundant and specialized groups of seabirds in the world. They are also an extremely diverse group, exhibiting a remarkable range of form and ecological adaptations. This volume takes an in-depth and comprehensive look at these fascinating seabirds. New field study findings are incorporated into the coverage of a wide range of aspects, including breeding biology, population ecology, evolution, and conservation. [Original APL blurb] The auks, or Alcidae, are one of the most specialized groups of seabirds. They are also an extremely diverse group, exhibiting a fascinating range of form and ecological adaptations. Moreover, they are the seabirds most vulnerable to man's activities, especially oil pollution, and hence are of great concern to conservationists. The last ten to fifteen years have seen an enormous amount of work on the auks, including a number of long-term field studies. This book summarizes, for the first time, the information gained on breeding biology, population ecology, evolution, and conservation of the group. As well as being interesting in their own right, the auks have proved useful as model species with which to explore the many themes and problems in ecology and evolution. The title of this book pays fitting tribute to Finn Salomonsen, who in 1944 wrote his own Atlantic Alcidae, a largely taxonomic work on the auks. The enormous amount of ecological information added to this by the present volume should enable a full appreciation of the group and of the special conservation problems which they face.
