Man and the land : an ecological history of fire and grazing on eastern Oregon rangelands

Creator:: Shinn, Dean Allison
Abstract:: Ecological and historical information are combined in examining the environmental influence of fire and grazing on rangelands in eastern Oregon through time. Competitive relationships between herbaceous and woody flora in the northern Great Basin are discussed, focusing broadly on the shrubsteppe regions 'of Franklin and Dyrness (1973) but with special...

Effect of western juniper on understory herbage production in Central Oregon

Creator:: Vaitkus, Milda R.
Abstract:: Evidence suggests that western juniper (Juniperus occidentalis) in Central Oregon affects understory production and composition. As trees increase in size and density, understory production is reduced and composition changes. This study was designed to identify the relationship between production and composition of understory vegetation and various tree canopy sizes of...

Geothermal exploration by telluric currents in the Klamath Falls area, Oregon

Creator:: Tang, Rex Wai-yuen
Abstract:: Geothermal resources are characterized by a very low electrical resistivity of the reservoir formations. The application of electrical methods in the reconnaissance type exploration for such resources is discussed. It is concluded that the magneto-telluric method is very well suited for this purpose. In 1971 and 1972 a reconnaissance type...

Response of Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) to defoliation of understory grasses and drought

Creator:: Purrington, Teal Mackenzie
Abstract:: Water potential, leaf conductance, growth, nitrogen content, and seedling survival of Wyoming Big Sagebrush (Artemisia tridentata ssp. wyomingensis) following defoliation of the herbaceous understory were assessed during two growing seasons. Precipitation was 107% and 63% of the long-term mean (283 mm) in 1989 and 1990, respectively, which presented an opportunity...

The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:: Johnson, Dustin D.
Abstract:: Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...

Life Cycle Assessments for Wastewater Treatment and the Feasibility Study of Microbial Fuel Cell Technology

Creator:: Chien, Ku-Huan
Abstract:: The thesis documents research about combining the National Pollutant Discharge Elimination System (NPDES) Permit Program with the Impact 2002+ methodology to conduct a Life Cycle Assessment (LCA) for wastewater treatment processes. The LCA for the operational phase of a local wastewater treatment plant was performed and the environmental impacts caused...

The skeletal basis of breast width in the domestic fowl

Creator:: Mahn, Siegfried
Abstract:: Several experiments were conducted with birds differing in body weight, conformation and sternal measurements to obtain information on whether it would be possible during short term selection to influence the shape of the sternum and, if so, what influence this would have on the amount and distribution of the breast...

Influence of spring crested wheatgrass production on intake of grazing steers

Creator:: Handl, William Paul
Abstract:: Research was initiated at the Squaw Butte Experimental Range in southeastern Oregon to study the influence of crested wheatgrass (Agropyron desertorum (Fisch.) Schult. ) herbage availability on relative dry matter intake (DMI) of yearling steers. Herbage dry matter production on an 18 ha range and daily fecal production of yearling...

Development and morphology of juvenile western juniper (Juniperus occidentalis Hook.)

Creator:: Kramer, Susanne
Abstract:: Whole tree excavation of 41 western juniper (Juniperus occidentalis Hook.), ranging in age from 2 to 34 years old, was used to assess the development and structure of root systems, to determine biomass allocation patterns, and to develop mathematical relationships for estimating biomass and root system dimensions in seedling and...
