Creator:: Lewis, Robert G. (Robert Gorden), 1959-
Abstract:: Stem growth, stem form development, and the dynamics of crown recession in young red alder (Alnus rubra Bong.) were studied by analyzing annual growth rings of stems and knots, annual height increments, projected crown areas, and branch diameters. Forty-one trees were sampled from three plantation spacing studies, representing ages 1...

Creator:: Bower, Andrew David
Abstract:: The goal of this study was to determine whether annual growth ring variables of young coastal Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) growing in progeny tests are sensitive to availability of soil moisture during the growing season. If ring variables are found to respond to soil moisture deficit (SMD)...

Creator:: Xiao, Ying
Abstract:: While microbial colonization of wood is presumed to be characterized by a myriad of interactions between numerous organisms, studying these processes is often difficult owing to the opaque nature of the wood and the inability to readily distinguish among the many species colonizing the material. One method for enhancing the...

Creator:: Heck, Leanne Renee
Abstract:: The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...

Creator:: Tahnk, William Richard
Abstract:: The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the winter monsoon, January-March. During the winter monsoon, polluted, low-level air from the Asian subcontinent blows over the Arabian Sea and...

Creator:: Zwieniecki, Maciej A.
Abstract:: Evaluation of meta-sedimentary bedrock as a source of stored water available to plants in a mediterranean climate is presented based on: root length distribution (RLD), root morphology, rock water holding capacity and seasonal pattern of water depletion. Studies were performed in southwestern Oregon under young stands of whiteleaf manzanita, ponderosa...

Creator:: Schrader, Barbara A.
Abstract:: Patterns of western hemlock regeneration were studied in relation to forest structural development and environment in the Oregon Coast Range. Density of western hemlock seedlings was examined across the climatic gradient from cool, moist coastal areas to the seasonally hot and dry Willamette Valley Margin. Seedling densities were most strongly...

Creator:: Poage, Nathan Jeremy
Abstract:: The tree species and size structure of 9l old-growth forests dominated by Douglas-fir in central western Oregon was characterized using complete inventories of all trees larger than 20cm dbh over a mean area of 17.1ha at each site. Douglas-fir accounted for over 75% of the total average basal area (39.1...

Creator:: Leitner, Beate
Abstract:: Two examples of Pacific rim plate boundary deformation are presented. In the first part of the thesis crustal models are derived for the northwestern part of the Vizcaino block in California using marine seismic and gravity data collected by the Mendocino Triple Junction Seismic Experiment. A northwest-southeast trending kink in...
