Fire effects on vegetation diversity, structure, and successional dynamics in shrub-steppe and mixed conifer environments of the Hells Canyon, Idaho

Creator:: Havlina, Douglas William
Abstract:: The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...

The effect of drought on the rate of photosynthesis, respiration, and transpiration in two ecotypes of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Zavitkovski, J.
Abstract:: The subject of this study was the determination of the changes in photosynthesis, respiration and transpiration in two ecotypes of Douglas-fir as caused by decreasing soil moisture content. The photosynthetic rate was also correlated with the relative turgidities of needles. All the above processes were greatly affected by decreasing soil...

Non-biological uptake of zinc-65 from a marine algal nutrient medium

Creator:: Tomlinson, Richard Douglas
Abstract:: The nature and magnitude of experimental errors due to ⁶⁵Zn adsorption by inorganic surfaces was examined in a laboratory system designed to measure ⁶⁵Zn uptake by marine phytoplankton. In the pH range, 6.3±.1 to 7.5±.1, a precipitate formed in the algal nutrient medium selected for the system. To this seawater-base...

Low Impact Development in the Ash Creek Watershed, Oregon : Feasibility Study and Implementation Tool Design

Creator:: Chalmers, Douglas R.
Abstract:: This study presents potential Low Impact Development (LID) solutions for the Ash Creek watershed and designs several tools to assist localities in implementing the solutions they may choose. Ash Creek is a tributary of the Willamette River flowing through Dallas, Monmouth, and Independence in Polk County, Oregon. Currently, Ash Creek...

Estimated net economic benefits to visitors of selected Columbia River fish hatcheries

Creator:: Larson, Douglas M.
Abstract:: This research has addressed an area of outdoor recreation economics which presents difficulties in estimation of demand and valuation. The focus was on visitors to three Columbia River fish hatcheries, and the net benefits realized from partaking in the recreational/educational experience which fish hatcheries offer. Three characteristics of the recreation...

Diurnal and seasonal changes in xylem water potential, stomatal conductance and abscisic acid in five different habitat types of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Murphy, Ellyn Margaret
Abstract:: Sapling Douglas-fir trees on five sites in the Coastal and Cascade Mountain ranges of Oregon were measured five times during the year from the summer of 1977 through the spring of 1978 for diurnal patterns of xylem water potential, stomatal conductance and abscisic acid. Vapor pressure deficit and solar radiation...
