The source area for coarse woody debris in small streams in western Oregon and Washington

Creator:: McDade, Mary Helen
Abstract:: Large organic debris has important biological and physical roles within the stream ecosystem. In order to determine the source area of large organic debris in streams, thirty-nine streams in the Cascade and Coast Ranges of Oregon and Washington were sampled. The distance from point-of-origin to channel was measured for thirty...

Dry coniferous forests in the Western Oregon Cascades

Creator:: Means, Joseph E.
Abstract:: Pseudotsuga menziesii dominates the forests of the Pacific Northwest. But though it is dominat, Tsuaa heteroohylla or Abies amabilis is usually climax. Many researchers have studied Pseudotsuga on the widespread mesic sites where it is seral, but few have examined the relatively rare ecosystems in which Pseudotsuga or its associate...

The reproductive ecology of the pacific yew (Taxus brevifolia nutt.) under a range of overstory conditions in western Oregon

Creator:: DiFazio, Stephen P.
Abstract:: The influence of overstory openness on the reproductive ecology of Pacific yew (Taxus brevifolia Nutt.) was investigated on 4 sites in western Oregon over 2 years. The breeding system of T. brevifolia was found to deviate from pure dioecy under a broad range of canopy and site conditions. Production of...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Landscape Genomics and Climatic Responses of Willamette Valley Alders

Creator:: Kral, George L.
Abstract:: The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...

Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:: Lewis, Katherine JoAnn
Abstract:: The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...
