This book was released on 2003-09-04 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book identifies accumulated environmental, social and economic effects of oil and gas leasing, exploration, and production on Alaska's North Slope. Economic benefits to the region have been accompanied by effects of the roads, infrastructure and activies of oil and gas production on the terrain, plants, animals and peoples of the North Slope. While attempts by the oil industry and regulatory agencies have reduced many of the environmental effects, they have not been eliminated. The book makes recommendations for further environmental research related to environmental effects.

Download or read book Ethology and Behavioral Ecology of Sea Otters and Polar Bears written by Randall W. Davis and published by Springer. This book was released on 2022-07-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Download or read book Blood Types in Pacific Salmon written by George J. Ridgway and published by . This book was released on 1960 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

Download or read book The Alaskan Beaufort Sea written by Peter W. Barnes and published by Elsevier. This book was released on 2013-09-17 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaskan Beaufort Sea: Ecosystems and Environments provides an interdisciplinary view into almost all aspects of the environment, with a detailed survey of the background literature. This book focuses on the Alaskan Beaufort Shelf environment. Organized into four parts encompassing 20 chapters, this book begins with an overview of the characteristics and history of the region in which the research took place and defines the objectives of the studies program. This text then examines the subsynoptic meteorological networks along the Beaufort Sea coast and shelf. Other chapters consider the thermally generated mesoscale effects on surface winds and the orographic mesoscale effects on surface winds. This book discusses as well the phytoplankton associations and relative phytoplankton production in the area between the 20-m depth contour and the edge of the ice in summer. The final chapter deals with the characteristics of the ice cover and oil-ice interactions that will affect cleanup activities after blowout. This book is a valuable resource for scientists and conservationists.

Download or read book The Fraser written by Bruce Hutchison and published by . This book was released on 2010-01-13 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: From one of Canada's greatest journalists comes the epic story of British Columbia's Fraser River. As the dust jacket for the originally edition-published half a century ago-declared:"Shaped like a giant fishhook stuck into the Pacific Ocean, the mighty Fraser is one of the most important rivers of North America, politically, economically, and historically. Compelling the reader's interest with the power and vigour of his narrative, Bruce Hutchison explores the Fraser's romantichistory as one of Canada's two main channels of civilization. The Fraser's story is that of British Columbia and its people, and Mr. Hutchison shows that it provides some of the richest yet least known chapters in Canadian history. These he unrolls in an unforgettable panorama, from the days ofSpanish discovery to the story of the city of Vancouver, the river's most remarkable product. In its gold, its steamboating, its fur; as a fisherman's paradise, and as the largest untapped source of electrical power in North America-the story of the Fraser is one of colour and high drama. It isexciting reading."The Wynford Edition includes a new introduction by Vaughn Palmer, one of Canada's foremost political journalists and a winner of the Bruce Hutchison Award. Palmer's introduction puts both the book and Hutchison's career in historical context for modern readers.

Download or read book Dear Chairwoman written by Syvliane Grant and published by . This book was released on 2021-04-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: DEDICATED TO THE NEXT GENERATION OF WOMEN BOARD LEADERSIn 2018, California passed a senate bill (SB 826) to require publicly held companies headquartered in CA to have at least one woman on their board by 2020. In 2020, Nasdaq proposed a mandate that would require listed companies to have at least two diverse board members with one member who identifies as female. Initiatives like these are helping advance gender parity on boards in many regions, not just the U.S. In late 2020, women held 22.6% of the board seats on the Russell 3000 for the first time, a 6.5 point jump over the past 4 years.Zooming out to the global scale, the picture is similarly improving. In 2020, about 23% of board seats globally were held by women, compared to 20% in 2018. Yet...at the time of this writing, 10% of large global companies do not have a single woman on their board. And the percent of women who chair boards is dramatically smaller. Among the largest 500 public U.S. companies by revenue the share of women who chaired boards remained stagnant at 7.4%. Notably, of those women who chair boards, few of them use the term Chairwoman in their bios or LinkedIn profiles-opting for monikers Chairman, or Board Chair, or occasionally Chairperson. This book features the extraordinary voices and stories of women leaders from around the world who have trailblazed to the board room, as letters to the next generation of women in business and government. With the salutation "Dear Chairwoman," these letters are infused with the energy to inspire young women to both pursue board governance early, and to claim the 'Chairwoman' title in taking the senior-most seat in the Board Room.

Download or read book Salmon written by P. T. K. Woo and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.
