Predictive mapping of landtype association maps in three Oregon national forests

Creator:: Peterman, Wendy L.
Abstract:: This study explores the use of predictive mapping techniques in developing Landtype Association (LTA) maps for use in natural resource management. These maps are produced for the USDA Forest Service on a regional basis at a 1:100,000 scale. The goal of this study is to develop and test a method...

Influence of atmospheric humidity on sporulation of Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor.

Creator:: Hural, Kirsten
Abstract:: The influence of atmospheric humidity on three aspects of sporulation of Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor., which causes rose powdery mildew, was studied on leaf disks of susceptible Rosa cultivar Samantha. To study conidiophore production, leaf disks were inoculated on the adaxial (upper) surface with conidia of S....

Influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers.

Creator:: Carre, Deborah Danielle
Abstract:: The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...

Pathogenic specialization and heterothallism in Sphaerotheca pannosa var. rosae

Creator:: Bender, Carol Lavane
Abstract:: Studies were conducted on pathogenic specialization and heterothallism in Sphaerotheca pannosa var. rosae, causal agent of rose powdery mildew. Methods were developed for isolation and identification of Sphaerotheca pannosa var. rosae races on rose. Monoconidial isolates were initiated on detached leaves, increased on host plants, and inoculated to rose cultivars...

Management and marketing strategies for high desert beef ranches in Eastern Oregon

Creator:: Panasuk, Eugene Duane
Abstract:: Ranchers in the high desert area of Eastern Oregon traditionally market their calves when they are weaned in late fall. This is the time when the market prices for calves are at a seasonal low. In this study the economic feasibility of various alternative management and marketing strategies for the...

Nitrogen fixation associated with grasses and other species in Oregon

Creator:: Nelson, Arthur Duane
Abstract:: Nitrogen fixation in both natural and domestic grasslands of Oregon was studied using the acetylene reduction assay. A substantial number of these tests made gave positive acetylene reduction activity. Rates in the range of 60g N₂ fixed/ha/day were observed for some Agrostis species. Assuming that this rate proceeds for 100...

Response of wood-boring beetles (Coleoptera: Buprestidae, Cerambycidae) to prescribed understory burning in mixed-conifer stands of southwestern Oregon

Creator:: Duane, Maureen V.
Abstract:: Prescribed burning is increasingly being used as a management tool to reduce potential fuels on the forest floor and promote stand vigor through removal of dense, crowded vegetation. Because fire affects both the standing vegetation and the amount of downed wood in the ecosystem, it is imperative to examine how...

Soil and understory vegetation characteristics of a tractor-logged forest in eastern Oregon

Creator:: Snider, Michael Duane
Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Land use distribution and changes in the urban-rural fringe area of South Albany, Oregon

Creator:: Nellis, M. Duane
Abstract:: The need to control irreversible conversions of prime agricultural lands to urban land uses has come to light in recent years. Resulting policy statements by the State of Oregon and federal agencies have added support to this premise. Nevertheless, inefficient conversions of agricultural to idle lands in response to urban...
