Spatial and temporal changes in stream network topology : post-eruption drainage, Mount St. Helens

Creator:: Parsons, Michael Raymond
Resource Type:: Dissertation

Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Creator:: Brandi-Dohrn, Florian M.
Abstract:: Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

A comparative analysis of stream response to disturbance in the Pacific Northwest

Creator:: Hodgins-Carlson, Terry Anne
Abstract:: Published literature about six Pacific Northwest stream systems was contrasted to provide a regional perspective on channel response to disturbance. This investigation was prompted by a combination of recent environmental legislation, mounting social pressures to plan projects at a drainage basin scale, and the difficulty in defining and predicting the...

Spatial analysis of soil depth variability and pedogenesis along toposequences in the Troodos Mountains, Cyprus

Creator:: Robins, Colin R.
Abstract:: In unstable landscapes, modern pedological research explores the role of soils as products and indicators of geomorphologic change. Understanding the dynamics of hill slope pedogenesis is especially important in regions with limited, poor, or threatened soil resources. The island of Cyprus, situated in the eastern Mediterranean, is claimed by many...

Community analysis of the Wyoming big sagebrush alliance and functional role of Wyoming big sagebrush

Creator:: Davies, Kirk W.
Abstract:: This study consisted of two research projects in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance, the most extensive of the big sagebrush complex in the Intermountain West. In the first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming big sagebrush...

Soil carbon and nitrogen in old-growth forests in western Oregon and Washington

Creator:: Remillard, Suzanne Marie
Abstract:: Soil organic carbon (SOC, kg C m-2) is an important component in evaluating global C stores. The nitrogen (TN, kg N m"2) cycle is closely linked to C and understanding its role is also important. Contents and distributions of SOC and TN in soil profiles, to 1-meter depth, were estimated...

Comparison of soil and vegetation map delineation shapes and areal correspondence

Creator:: Bilton, Janet
Abstract:: Map delineations of soil and vegetation for a 14,000 acre (5,800 hectare) site in the Oregon Coast Range were compared. Research objectives were to ascertain the types of information that could be extracted from delineation comparisons and to develop a methodology suited to this purpose. The latter objective was achieved...

The mineralogy and morphology of loess derived soils along a traverse in northeastern Oregon

Creator:: Berggren, Brad J.
Abstract:: The lentil strain of pea seedborne mosaic virus, PSbMV-L, was distinguished from the standard isolates of PSbMV by a natural inoculum reservoir in lentil seed and by separate resistance genes in Pisum and Lens. PSbMV-L was intermediate in symptom severity between the standard and New Zealand isolates of PSbMV. Seed...

Conservation of Sidalcea nelsoniana through habitat management : effects of burning, mowing, and altered flooding regime on a rare Willamette Valley perennial

Creator:: Bartels, Marilynn R.
Abstract:: Active habitat management plays a key role in the preservation of native ecosystems and rare species, especially in the Willamette Valley of Oregon, where natural succession to woodlands threatens the few wetland prairies remaining after 150 years of agriculture and urbanization. Sidalcea nelsoniana, listed as threatened under the federal Endangered...
