Sugar transport in strawberry fruit : uptake competition and developmental changes in invertase levels

Creator:: Scott, James Douglas
Abstract:: Mechanisms by which plant organs accumulate photoassimilate are important in determining final sink size and may involve invertase activity. Because strawberry fruit are strong sinks for sugars, changes in invertase levels during development and mechanisms of sugar uptake within the fruit were examined. Fruit from greenhouse-grown, day-neutral strawberries, (Fragaria X...

The effects of mechanical damage on residual coastal Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) following commercial thinning

Creator:: Kiser, James D.
Abstract:: Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

Influence of protein supplementation frequency on cows consuming low-quality forage : performance, grazing behavior, and variation in supplement intake

Creator:: Schauer, Christopher Scott
Abstract:: Our objective was to determine the influence of CP supplementation frequency (SF) on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred-twenty pregnant (approx....

Simulating Wood Properties in the Context of a Growth and Yield Model for Planted Douglas-fir

Creator:: Osborne, Nathaniel L.
Abstract:: Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...

Algorithms for massive biological datasets

Creator:: Bryant, Douglas W. (Douglas Wesley)
Abstract:: Within the past several years the technology of high-throughput sequencing has transformed the study of biology by offering unprecedented access to life's fundamental building block, DNA. With this transformation's potential a host of brand-new challenges have emerged, many of which lend themselves to being solved through computational methods. From de...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

On the Properties and Characteristics of Solution Processed Hafnium Based Thin-Films from Aqueous Precursors

Creator:: Decker, Shawn R.
Abstract:: Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...

A policy preference function analysis of the forest sector in the Cote d'Ivoire

Creator:: Yapi, Atse
Abstract:: The main objective of this study was to offer an alternative methodology for forest sector modeling in developing economies. To this effect, a policy preference function was developed and estimated using data from the forest sector of the Cote d'Ivoire. The justification for this alternative framework for forest sector analysis...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...
