Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

The Role of Community Cultural Wealth in the Retention of Latino/a Students in the Community College Setting

Creator:: Reeder, Jane F.
Abstract:: Background. Many studies addressing the reasons why minority students fail in higher education are based on what is defined as a deficit model. A deficit model documents that a significant number of minority students fail because their culture is distinct from that of the majority population. Numerous minority students do...

Oils Colored with Wood-Staining Fungal Pigments : Color Loss, Oxidation, and Structural Breakdown

Creator:: Hinsch, Eric M.
Abstract:: Wood-staining fungal pigments have potential uses as colorants for wood and textiles. Traditionally, organic solvents have been used as carriers for these pigments. However, other environmentally-friendly and more readily available carriers must be found. Natural oils have the potential to carry these pigments but have demonstrated color loss over relatively...

Biology, ecology and management of Scaptomyza apicalis Hardy (Diptera : Drosophilidae) on meadowfoam, Limnanthes alba benth in western Oregon

Creator:: Panasahatham, Sarote
Abstract:: Biology of Scaptomyza apicalis Hardy (Diptera: Drosophilidae) was studied in relation to its host, meadowfoam, Limnanthes alba, a recent oil seed crop grown in the Willamette Valley, Oregon. Populations of flies and larvae were monitored weekly over three consecutive crop-years beginning in 1996. Yellow sticky traps gave relative population estimates...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...
