Book Description
Winner of the Pacific Northwest Booksellers Award Bounded on the east by the crest of the Cascade Range and on the west by the lofty east flank of the Olympic Mountains, Puget Sound terrain includes every imaginable topograhic variety. This thoughtful and eloquent natural history of the Puget Sound region begins with a discussion of how the ice ages and vulcanism shaped the land and then examines the natural attributes of the region--flora and fauna, climate, special habitats, life histories of key organisms--as they pertain to the functioning ecosystem. Mankind's effects upon the natural environment are a pervasive theme of the book. Kruckeberg looks at both positive and negative aspects of human interaction with nature in the Puget basin. By probing the interconnectedness of all natural aspects of one region, Kruckeberg illustrates ecological principles at work and gives us a basis for wise decision-making. The Natural History of Puget Sound Country is a comprehensive reference, invaluable for all citizens of the Northwest, as well as for conservationists, biologists, foresters, fisheries and wildlife personnel, urban planners, and environmental consultants everywhere. Lavishly illustrated with over three hundred photographs and drawings, it is much more than a beautiful book. It is a guide to our future.

Book Description
Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.
