An analysis of hedging soft white wheat using the Chicago wheat futures market

Creator:: Levy, Robert Louis
Abstract:: In 1970, the Pacific Northwest (PNW) produced approximately 145,332,000 bushels of wheat (all types) with an average harvest value of over $220,000,000. White wheat comprised about 126,234,000 bushels of that total, about 87 percent. In recent years the financial circumstances, for several reasons, have deteriorated for many farmers and grain...

Seasonal response of bitterbrush to burning and clipping in eastern Oregon

Creator:: Clark, Robert G.
Abstract:: Bitterbrush [Purshia tridentata (Pursh) DC] plants were burned or clipped, fall and spring, under different soil moisture conditions on two sites in east-central Oregon. Treatments, on plants of an erect growth form on the Juniperus/Artemisia-Purshia site resulted in 38% of the fall-clipped and 40% of the spring-clipped plants sprouting. None...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

A dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

Creator:: White, Robert Lewis, II
Abstract:: Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...

Water relations and the root regeneration response of Douglas-fir

Creator:: Cobb, Cheryl Anne
Abstract:: The effect of lifting date and root-pruning treatments on water potential, root regeneration, and shoot growth of six-month-old and three-year-old Douglas-fir seedlings bare-root transplanted into a growth chamber, and sawdust bed, respectively, was studied. Root growth in six-month-old and three-year-old seedlings was highest in February and August respectively. Survival was...

Habitat factors affecting pronghorn use of playas in south central Oregon

Creator:: Good, James Ronald
Abstract:: Pronghorn (Antilocapra americana) use of four playas (intermittent lakebeds) on Hart Mountain National Antelope Refuge (NAR) in south central Oregon was studied during the summers of 1974 and 1975. Percent canopy cover of playa vegetation, plant phenology, percent desiccated vegetation, soil moisture, available surface water and pronghorn use of range...

Genesis of some soils in the central western Cascades of Oregon

Creator:: Brown, R. B.
Abstract:: Soils representative of several landscape units in the H. J. Andrews Experimental Forest, Western Cascade Range, were sampled, analyzed, and tentatively classified. Genetic inferences were drawn relating soils to landscape position and other factors of soil formation. Descriptive information and nutrient capital data were provided to support ecosystem modelling efforts...
