Historical and Current Presence-absence of Coho Salmon (Oncorhynchus Kisutch) in the Central California Coast Evolutionary Significant Unit by Peter Burton Adams Pdf

"This report is a summary of the presence and absence of coho salmon, Oncorhynchus kisutch, in streams in the Central California Coast Evolutionary Significant Unit (ESU). Only streams with historical records of coho occupancy are considered. It has been prepared to assist in Endangered Species Act activities... Presence absence data used here come from surveys conducted for this study and fron data collected by other researchers. A preliminary report of this data, which included only approximately one-half of these streams, was published earlier... to meet earlier listing requirements."--p.Abstract.

Historical and Current Presence-absence Data of Coho Salmon (Oncorhynchus Kisutch) in the Central California Evolutionary Significant Unit by Anonim Pdf

A summary of the presence and absence of coho salmon, Oncorhynchus kisutch, in streams in the Central California Evolutionary Significant Unit (ESU) with historical records of this species has been prepared to assist in the Endangered Species Act listing process. Presence-absence data were used because of: 1) the short time frame indicated by the listing process, and 2) the use of presence-absence data in pre-listing documents. Presence-absence data used here come form surveys conducted for this study and from data collected by other researchers. Coho salmon were absent from 50% of the historical record streams. This figure is similar to reports by earlier researchers. The percent of historical record streams with coho salmon absent is highest in the highly urbanized San Francisco Bay and the lowest in coastal Marin County. Percent of absence was also high in Sonoma County, with other areas being roughly equal.

Monitoring Ecological Condition in the Western United States by Shabeg S. Sandhu,Brian D. Melzian,Edward R. Long,Walter G. Whitford,Barbara T. Walton Pdf

The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems. With the controls on point sources reducing chemical contamination, new environmental challenges associated with nonpoint sources have emerged. To adequately deal with these new problems, EPA's Office of Research and Development recognized the need to develop an overall under standing of the condition of our ecological resources, the trends in their condition, and the stressors affecting these systems on a broad scale. Toward this end, the En vironmental Monitoring and Assessment Program (EMAP) was established by EPA and has been strategically developing the scientific tools and techniques to monitor and assess the status and trends of aquatic ecosystems. EMAP scientists have developed new indicators and probability-based de signs to fill data gaps in the development of regional-scale assessments of our aquatic resources, as required in the Clean Water Act. We have a scientifically de fensible approach that allows: 100 percent coverage of the aquatic resources within broad geographic areas and the formulation of reference 'conditions for es tablishing the health of these resources. The use of these indicators and designs were successfully demonstrated in the landscapes, streams, and estuaries of the mid-Atlantic states as part of the Mid-Atlantic Integrated Assessment (MAlA).

Pacific Salmon Life Histories by Cornelis Groot,L. Margolis Pdf

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.
