The stability of pelargonidin-based anthocyanins in natural and model systems

Creator:: Garzon, G. Astrid
Abstract:: Pelargonidin 3-glucoside (pgd 3-glu), pelargonidin 3-sophoroside (pgd 3-soph), and pelargonidin 3-sophoroside 5-glucoside acylated with cinnamic and malonic acids (acyl-pgd 3-soph 5-glu) were extracted from strawberries (Fragaria anannassa cv, Totem), nasturtium flowers (Tropaeolum majus), and radish peel (Raphanus sativus L. cv, fuego), respectively. Their stability was studied in natural and model...

Delineating pattern and process in tropical lowland : mealy parrot migration dynamics as a guide for regional conservation planning

Creator:: Bjork, Robin D.
Abstract:: Most reserves fail to capture the habitat heterogeneity necessary to maintain viable populations of wide-ranging species. Methods to determine defensible dimensions of reserves and reserve networks are needed. The primary goal of this study was to develop such methods for lowland tropical forests by examining habitat- and spatial-use patterns of...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

Creator:: Freidenburg, Tess L.
Abstract:: Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

Assessment of ground water recharge and quality under agricultural production in Lane County, Oregon

Creator:: Shelby, Patrick M.
Abstract:: Assessment of the environmental impacts of an agricultural production system requires information on both soil water quality and solute flux. Passive Capillary Samplers (PCAPS), which sample water from the vadose zone using fiber glass wicks, have shown potential to provide both flux and solute concentration in unsaturated zone sampling but...

Characterization of biochemical, functional properties, and market potential of Pacific whiting fish sauce

Creator:: Tungkawachara, Somjintana
Abstract:: Biochemical properties, functional properties, and market potential of Pacific whiting (PW) fish sauce were investigated. Biochemical properties of fish sauce made from whole fish (W) and a mixture (1:1) of whole fish and surimi byproducts (WB) were compared. Market potential was evaluated through phone interviews and consumer panelists. Proteolysis was...

Factors affecting the dynamics and regulation of coral-reef fish populations

Creator:: Webster, Michael Scott
Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

Diagnostic tools for overdispersion in generalized linear models

Creator:: Ganio-Gibbons, Lisa M.
Abstract:: Data in the form of counts or proportions often exhibit more variability than that predicted by a Poisson or binomial distribution. Many different models have been proposed to account for extra-Poisson or extra-binomial variation. A simple model includes a single heterogeneity factor (dispersion parameter) in the variance. Other models that...
