Quality of bluebunch wheatgrass (Agropyron spicatum) as a winter range forage for Rocky Mountain Elk (Cervus elaphus nelsoni) in the Blue Mountains of Oregon

Creator:: Bryant, Larry Duane
Abstract:: This research was conducted on three study areas on elk winter ranges in Northeast Oregon. One was on the Starkey Experimental Forest and Range and the others were in the same vicinity. Plant appendages, spring and fall defoliation and fall growth of bluebunch wheatgrass were evaluated in terms of quality...

Canopy epiphyte studies in the central Oregon Cascades : implications for the management of Douglas-fir forests

Creator:: Sillett, Stephen Charles
Abstract:: This thesis includes four separate studies. The first two studies assessed edge effects in a 700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge were similar to those of the forest interior, but there were some differences in vertical distribution patterns. Several species restricted to the...

Regional gradient analysis and spatial pattern of woody plant communities in Oregon

Creator:: Ohmann, Janet L.
Abstract:: Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...

Somaclonal variation, regeneration and transformation of quince (Cydonia oblonga Mill.) and pear (Pyrus communis L.)

Creator:: Bunnag, Sumonthip
Abstract:: Quince (Cydonia oblonga Mill.) is widely used as a dwarfing rootstock for pear {Pyrus communis L.). The disadvantage of this rootstock is its inefficient uptake of Fe, resulting in leaf chlorosis. Application of tissue culture and gene transfer techniques may lead to production of quince clones with improved Fe efficiency....

A cost effectiveness analysis of actions to reduce stream temperature : a case study of the Mohawk watershed

Creator:: Mooney, Sian, 1965-
Abstract:: The concept of ecosystem management requires that management prescriptions account for economic and environmental goals that are measured in non-commensurate units. This study examines the economic and environmental trade-offs associated with planting a riparian buffer in trees to reduce stream temperatures in the Mohawk watershed, Oregon. The detrimental effects of...

The effects of growth rate and cambial age on wood properties of red alder (Alnus rubra Bong.) and Oregon white oak (Quercus garryana Dougl.)

Creator:: Lei, Hua
Abstract:: This study was to investigate effects of growth rate and cambial age on properties of wood from two increasingly used hardwood species, red alder (Alnus rubra Bong.) and Oregon white oak (Quercus garryana Dougl.), for better understanding factors affecting wood quality in hardwoods. Thirty 7-year-old trees grown at widely varying...

Evolution and ecology of the Ceanothus-Frankia symbiosis

Creator:: Jeong, Soon-Chun
Abstract:: The evolutionary relationship between Frankia and actinorhizal plants was evaluated by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia strains. Although the branching order...
