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.
Download or read book Birds of Ontario Habitat Requirements Limiting Factors and Status written by Al Sandilands and published by UBC Press. This book was released on 2011-01-01 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volumes in the Birds of Ontario series summarize life history requirements of bird species that are normally part of the ecology of Ontario. This is the second volume in the series and completes the treatment of the nonpasserine bird species occurring in Ontario on a regular basis. Information on habitat, limiting factors, and status is summarized for 83 species in this volume. These topics are covered for the three primary avian seasons: breeding, migration, and winter. Habitat, nest sites, territoriality, site fidelity, annual reproductive effort, habitat loss and degradation, environmental contaminants, and a variety of other topics are covered in the species accounts. Maps depicting breeding and wintering range are presented for most species along with drawings by Ross James. Birds of Ontario is an essential reference source for wildlife biologists, environmental consultants, and planners preparing or reviewing environmental impact statements and environmental assessments. Serious birders will find the volumes of interest as well. Although the books focus on Ontario birds, the information is highly relevant to adjacent provinces and states.
Download or read book Population Ecology Studies of the Polar Bear in Northern Labrador written by Ian Stirling and published by . This book was released on 1980 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: "During spring 1976-79 we marked and recaptured polar bears in northern Labrador. Thirty-seven polar bears were captured and individually tagged. Most were found along the interface between the coastal landfast ice and the drifting pack ice, especially around the mouths of bays. The mark and recapture data indicated a low population (60-90 bears) in the area. Fifty to 80% fewer polar bears and tracks were seen per 100 km of potential habitat surveyed than recorded for other areas of the Arctic. This also indicates a smaller population"--Abstract.

Download or read book Muddy Coasts of the World written by Terry R. Healy and published by Gulf Professional Publishing. This book was released on 2002 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SCOR (Scientific Committee on Ocean Research of ICSU) Working Group 106 was tasked with reviewing the geomorphic, sedimentary and oceanographic dynamics of muddy costs, assessing the impact of sea level rise on muddy coasts, especially in estuaries, and to recommend future research pathways relating to muddy coasts. This book addresses these questions and includes chapters on the research issues of muddy coasts, the definition of muddy coasts, sea level rise effects on muddy coasts, fundamental dynamic processes effecting muddy coast formation, the role of mangrove and salt marsh vegetation, bio-geochemistry of muddy coast deposits, storm surge effects on muddy coasts, human impacts on muddy coasts, and a detailed geographical review of muddy coasts of the world. The volume presents examples of muddy coasts sedimentation from many different environments of the world including the broad expanse muddy coast of China, muddy coasts of continental trailing edges (the Americas), muddy coasts in seasonally ice covered environments, muddy coasts in areas of tropical coral reefs, muddy coasts from the tropics, muddy coasts resulting from large river discharges, and muddy coasts of mid-latitude oceanic islands.

Available in PDF, EPUB and Kindle. Book excerpt: "The northeast coast of James Bay was chosen for study because of its importance as a staging area for migrating geese and because of the development of the La Grande hydroelectric complex, the main structures of which are along the La Grande River, which empties into the northeastern part of James Bay. In 1990 and 1991, use of coastal habitats by Canada Geese Branta canadensis and Atlantic Brant B. bernicla hrota was studied along the northeast coast of James Bay"--Abstract.
