Utilizing GIS for the collection of key variables in the analysis of an international freshwater basin spatial database

Creator:: Fiske, Gregory J.
Abstract:: The Geographic Information System (GIS) is an invaluable tool in manipulating and interpreting world scale datasets. In recent years it has become the standard link between water resource study and the ever-increasing numbers of high quality data sets. This paper describes the use of Geographic Information Systems for gathering and...

The flight and olfactory behavior of checkered beetles (Coleoptera cleridae) predatory on the douglas-fir beetle

Creator:: Harwood, Willard Garland
Abstract:: Three coleopterous predators associated with the Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins in a second growth forest of Douglas-fir (Pseudotsugae menziesii (Mirb. ) Franco) in western Oregon are Enoclerus sphegeus Fabriciup, E, lecontei Wolcott, and Thanasirnus undatulus Say. A study was undertaken with the following objectives: (1) to determine the diurnal...

Comparing measures of beliefs about drug-taking compliance

Creator:: Hasuike, Betty Louise
Abstract:: The purpose of this study was to examine the relationship between two different methods of measuring beliefs about drug-taking compliance and the behavior of drug-taking compliance, and to compare the predictive ability of the two methods of measuring beliefs about drug-taking compliance. The belief examined was perceived seriousness, a health...

Drivers of Productivity Differences between Native and Exotic Range Douglas-fir Plantations in Oregon and New Zealand

Creator:: Gilson, Liam W.
Abstract:: In this thesis, we first examine the principle hypotheses behind the improved exotic growth of select timber species, and the evidence for each, with special focus on studies which examine growth between several ranges of a species. We find that literature suggests environmental factors directly tied to net primary production...

Douglas-fir (Psuedotsuga menziesii) biomass and nutrient removal under varying harvest scenarios involving co-production of timber and feedstock for liquid biofuels

Creator:: Coons, Kristin L.
Abstract:: In this study an improved model of biomass and nutrient estimation of coastal Douglas-fir (Psuedotsuga menziesii) in the Pacific Northwest has been developed across a wide range of stand management regimes. This study quantifies and defines the type and intensity of biomass harvest and associated removal for actively managed stands...

Impact of Climate and Disturbance on the Formation of Earlywood and Latewood in Douglas-fir at the Salal Fields Study Site

Creator:: Gourley, Derek M. F.
Abstract:: Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the...

Estimation of leaf area index and simulation of evapotranspiration for intensively managed Douglas-fir forests

Creator:: Rogers, Nicole S.
Abstract:: Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...

Alterations in Douglas-fir crown structure, morphology, and dynamics imposed by the Swiss needle cast disease in the Oregon Coast Range

Creator:: Weiskittel, Aaron R.
Abstract:: Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...
