The free radical scavenging system in overcoming phytotoxicity and breaking dormancy

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) induced earlier budbreak, more uniform and a higher percentage of budbreak in resting poplar (Populus alba x P. gradidentata, NC 5339) plants. However, it was phytotoxic to poplar when applied at 0.5 M or higher concentrations. Percent budbreak increased and percent dieback decreased when poplar plants were...

Quality management factors and related performance measures in the cooperative extension system

Creator:: Boltes, Barbara V.
Abstract:: The purpose of this study was to identify the critical factors for effective quality management in the Cooperative Extension System (CES) and develop an instrument that measured quality management performance in selected CES organizations as a means of identifying organizational training needs. Three procedures were applied in this study. First,...

Post-eruption recovery and secondary production of grazing insects in two streams near Mt. St. Helens

Creator:: Meyerhoff, Richard Dietrich
Abstract:: The eruption of Mt. St. Helens provided the opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...

Representations and algorithms for efficient inference in Bayesian networks

Creator:: Takikawa, Masami
Abstract:: Bayesian networks are used for building intelligent agents that act under uncertainty. They are a compact representation of agents' probabilistic knowledge. A Bayesian network can be viewed as representing a factorization of a full joint probability distribution into the multiplication of a set of conditional probability distributions. Independence of causal...

Canopy epiphyte studies in the central Oregon Cascades : implications for the management of Douglas-fir forests

Creator:: Sillett, Stephen Charles
Abstract:: This thesis includes four separate studies. The first two studies assessed edge effects in a 700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge were similar to those of the forest interior, but there were some differences in vertical distribution patterns. Several species restricted to the...

Oceanographic influences on rocky intertidal communities : coastal upwelling, invertebrate growth rates, and keystone predation

Creator:: Sanford, Eric (Eric David)
Abstract:: The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...

The effects of biomechanical and ecological factors on population and community structure of wave-exposed, intertidal macroalgae

Creator:: Blanchette, Carol A.
Abstract:: I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...

Partial purification and characterization of a zeatin Cis-trans isomerase from Phaseolus vulgaris L.

Creator:: Bassil, Nahla V.
Abstract:: Conversion of exogenous cis-zeatin to trans-zeatin in immature seeds of Phaseolus vulgaris L. led to the isolation of a cis-trans isomerase from the endosperm. The enzyme was purified over 2000-fold by chromatography on a series of FPLC (anion exchange, gel filtration, and hydrophobic interaction) and Concanavalin A columns. Non-enzymatic isomerization...
