The effects of thinning on forest-floor small mammals in the Coast Range of Oregon

Creator:: Larson, David J.
Abstract:: Thinning of young Douglas-fir forests has the potential to enhance structural diversity and improve habitat for wildlife. I examined the effects of thinning and thinning intensity on abundance and demographic characteristics of forest-floor small mammals in the Coast Range of Oregon 5 and 6 years after thinning had occurred. Thinning...

Mapping of quantitative trait loci for malting quality in a winter X spring barley (Hordeum vulgare, L.) cross

Creator:: Oziel, Adeline M.
Abstract:: Making quality and winterhardiness in barley are "ultimate" phenotypes composed of component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of barley was used, in conjunction with multi-environment phenotypes for grain yield and malting quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:: Lu, Shengjun
Abstract:: Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Tillering, lodging, dry matter partitioning, and seed yield in ryegrass (Lolium spp.) as affected by the plant growth regulator paclobutrazol

Creator:: Hunter, James L.
Abstract:: Seed yield in ryegrass (Lolium spp.) is the product of the number of fertile tillers per unit area and seed weight per spike at maturity. These components of yield develop through a series of growth stages beginning with tiller bud initiation and finishing with seed filling. Environmental conditions during plant...

Determination of Total Nucleotides, Nitrogenous Bases and Degradation By-Products with Respect to Various Processing and Preservation Techniques for Alaska Pollock (Gadus chalcogrammus) and Yellowfin Sole (Limanada aspera)

Creator:: Nelson, Kevin A.
Abstract:: The primary goal of this research was to determine the concentration and composition of nucleotides, as nucleoside monophosphates and nucleobases, in the underutilized reproductive organs (milt and roe) of Alaska pollock (Gadus chalcogrammus) and yellowfin sole (Limanda aspera). Changes in concentrations of these nucleotides and nucleotide analogs were observed with...

Physiological and biochemical characteristics of two cultivars of tall fescue (Festuca arundinacea Schreb.) under different environmental conditions

Creator:: Fino, Antonio Carlos
Abstract:: Two cultivars of tall fescue (Festuca arundinacea Schreb.) with contrasting growth habits were studied under field and growth chamber conditions. Fawn, an established cultivar since 1964, and TFM, an experimental line, were observed to grow better during spring and fall months respectively, in the field. Different temperature regimes of 10/4,...

Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

Creator:: Ambauen, Spencer J.
Abstract:: A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...
