DOWNLOAD EBOOKRivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. - Provides a single source of information on North America's major rivers - Features authoritative information on more than 200 rivers from regional specialists - Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system - Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

DOWNLOAD EBOOKDiscusses the mark-recapture studies of adult Chilkat River sockeye (Oncorhynchus nerka) and chum (O. keta) salmon in 2003 and 2004 by the Alaska Department of Fish and Game and the Northern Southeastern Regional Aquaculture Association. These studies were done in order to estimate the escapement of chum and sockeye salmon in the Chilkat River, and sockeye salmon in Chilkat Lake, and to summarize age, sex, and length compositions for these populations.

DOWNLOAD EBOOKMany species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.

DOWNLOAD EBOOKCo-published with UNESCO A product of the UNESCO-IHP project on Water and Cultural Diversity, this book represents an effort to examine the complex role water plays as a force in sustaining, maintaining, and threatening the viability of culturally diverse peoples. It is argued that water is a fundamental human need, a human right, and a core sustaining element in biodiversity and cultural diversity. The core concepts utilized in this book draw upon a larger trend in sustainability science, a recognition of the synergism and analytical potential in utilizing a coupled biological and social systems analysis, as the functioning viability of nature is both sustained and threatened by humans.

DOWNLOAD EBOOKPacific 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.
