Non-native and native plant species distributions and variability along an elevation gradient in the Wallowa Mountains, Oregon

Creator:: Averett, Joshua P.
Abstract:: Invasion by non-native plants into natural areas is an important component of global change that threatens biodiversity and ecosystem structure and function. Mountains are currently among the least invaded ecosystems, however, these biodiversity hotspots are increasingly under threat of exotic plant invasion. Evaluation of plant species distribution patterns in mountain...

Interactions of cattle and chinook salmon

Creator:: Ballard, Teena M.
Abstract:: Spring chinook salmon spawning occurs in late summer when it is common for cattle to be present in pastures that have streams where fish spawning occurs. This two-year study addressed three main objectives relative to behavioral interactions between cattle and spring chinook salmon during the spawning life history stage. These...

Evidence, explanations, and recommendations for teachers' field trip strategies

Creator:: Rebar, Bryan M.
Abstract:: Field trips are well recognized by researchers as an educational approach with the potential to complement and enhance classroom science teaching by exposing students to unique activities, resources, and content in informal settings. The following investigation addresses teachers' field trip practices in three related manuscripts: (1) A study examining the...

Effects of insecure attachment on marital interactions : examining the family stress model

Creator:: Wicks, Steven M.
Abstract:: This exploratory study posited that being in an insecure marriage would increase marital conflict and perceived relational aggression when the couple is experiencing economic constraints. The cross-sectional design assessed two groups of marriages: secure and insecure. A structural equation model using multiple group comparison tested the effect of each type...

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...

Production of C4-C10 Hydrocarbons from CO₂, H₂O, CO, H₂ and CH₄ Utilizing DC Glow Discharges, Catalytic Rapid Temperature Pulsing in Micro-Scale Reactors.

Creator:: Mohamed, Omar M.
Abstract:: This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...

The role of formative outdoor and family experiences on environmental belief formation in children and this role's implications for environmental education

Creator:: Smith, Vincent M.
Abstract:: The purpose of this research was to determine the role of formative experiences in the home and family pertaining to environment on children's overall environmental beliefs. Students attending environmentally related and non-environmentally related summer camps at a children's science museum served as test subjects in this study. A written instrument...

Marking, movement, and management of Drosophila suzukii in Oregon berry crops

Creator:: Klick, Jimmy
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...

Distribution and behavior of cattle grazing riparian pastures

Creator:: Wilson, Marie A. (Marie Annette)
Abstract:: One second GPS collars were deployed on cattle in three different pastures at three separate times during the year. In each riparian pasture the vegetative communities and stream bank edge were digitally mapped using low elevation aerial photographs and checked in the field for accuracy. A 5 m buffer zone...

The Eco-hydrology of Tropical Peatlands Associated with Land Cover Changes

Creator:: Kurnianto, Sofyan
Abstract:: Tropical peatlands play an important role in global climate system by storing an immense of carbon that had been accumulated over thousands of years. Peatlands provide another important ecosystem service by regulating the hydrology. It is believed that peatlands act like a giant sponge by absorbing substantial amounts of water...
