Regional variation of pull factors for retail sales in Oregon's nonmetropolitan counties 1979, 1982, 1984

Creator:: Corcoran, Patrick
Abstract:: The performance of pull factors for total retail sales in Oregon's nonmetropolitan counties during the economic cycle of boom, bust, and recovery of the early 1980s is examined for geographic patterns. One regional pattern and several county patterns are identified and discussed. Counties having the highest and lowest pull factors,...

Impacts of instream flows on the Colorado River Delta, Mexico : spatial vegetation change analysis and opportunities for restoration

Creator:: Zamora-Arroyo, Jose Francisco
Abstract:: Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...

The Role of Southern Oregon's Coastal Islands in Prehistoric Subsistence

Creator:: Gard, Howard A.
Abstract:: The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more...

Thornthwaite's moisture index as a measure of the intensity to which harvested cropland is devoted to corn under natural climatic conditions

Creator:: Hall, Robert Newell
Abstract:: Moisture has long been identified as one of the major limiting factors in the distribution of agricultural land use practices. However, the importance of any environmental element can only be determined by considering how it is affected by its relationship with other elements of the environment. Thornthwaite's moisture index attempts...

The influence of aging dams and geography on the distribution of dam removals in the United States

Creator:: Ashley, Sara
Abstract:: Over 470 dams have been removed in the United States, and a significant increase in dam removals has occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals; as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...

An evaluation of the Earth Resources Technology Satellite (ERTS-1) multispectral scanner as a tool for the determination of lacustrine trophic state

Creator:: Boland, Dale H. P.
Abstract:: This study evaluates the Earth Resources Technology Satellite- One (ERTS-1) multispectral scanner (MSS) as a means of predicting lacustrine trophic state and the magnitude of selected trophic state indicators. Numerical classificatory methods are employed to ascertain the trophic character of 100 lakes in Minnesota, Wisconsin, Michigan, and New York using...
