The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...
South American waterweed, Elodea densa (Planch.) Casp., and Coontail Ceratophyllum demersum L., were studied for their potential to take up chromium and zinc and as a possible indicator of arsenic, cadmium, copper, and lead pollution. Plants were collected from the Willamette River in Oregon and exposed for 48 hours to...
Despite the clear negative impact of high textbook costs on students, limits including space, funding, and policies prevent many academic libraries from fully supporting textbook collections. Partnering with other campus units on textbook lending requires creative thinking but can provide students access to other services in addition to the books...
The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...
The path of the Antarctic Polar Front (PF) is mapped using satellite sea surface temperature data from the NOAA/NASA Pathfinder program. The mean path and variability of the PF are strongly influenced by bathymetry. Meandering intensity is weaker where the bathymetry is steeply sloped and increases in areas where the...
The accessions used in this study were comprised of 246 snap bean and 49 dry bean genotypes. Of these, 150 snap bean accessions came from the Common Bean Coordinated Agriculture Project Snap Bean Diversity panel, an assemblage of 59 Chinese snap bean genotypes obtained from a trip to China in...
