Nitrogen and phosphorus dynamics during decomposition of multiple litter types in temperate coniferous forests

Creator:: van Huysen, Tiffany L.
Abstract:: Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

The impact of Saccharomyces and non-Saccharomyces yeast on the aroma and flavor of Vitis vinifera L. cv. 'Pinot Noir' wine

Creator:: Takush, David G.
Abstract:: The impact of yeast on the aroma and flavor of Vitis vinifera L. cv. 'Pinot Noir' wine was investigated. Due to the presence of naturally occurring yeast and bacteria on grapes and wine equipment, and the influence these microorganisms have on wine, a means of eliminating microorganisms from grape must...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Vegetation and soil microbial communities three years after wildfire in spruce-fir forests of northwestern Wyoming

Creator:: Hooke, Jennifer Suzanne
Abstract:: The Normalized Burn Ratio and Composite Burn Index were used to classify burn severity in three sites that experienced lightning-ignited wildfire in the year 2000. The effect of burn severity (unburned, low, moderate, and high severity classes) was investigated on vegetation and soil microbial community composition. Vegetation communities showed a...

Creator:: Aguilar, Joseph R.
Abstract:: This novel-in-progress is an attempt to struggle with the complicated process of forging one’s identity in the murk of urban Northwest life. The protagonist of this piece is confused, to put it lightly: bi-racial, torn between the affections of divorced parents, unsure about his religious views, and baffled by his...

Innovativeness and acceptance of retirement housing of faculty pre-retirees at selected Thai universities

Creator:: Buasri, Virajada
Abstract:: Changing demographics and lifestyles in Thailand are eroding traditional patterns of family support for the elderly. Caring for the elderly within the family structure is no longer assured. However, the concept of living in retirement housing is unfamiliar to most senior Thai citizens. The purpose of this study was to...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...

The methodology, implementation, and analysis of the isotopic composition of soil respired CO₂ in forest ecological research

Creator:: Kayler, Zachary Eric
Abstract:: Soils are the largest terrestrial pool of carbon, therefore it is critical to understand what controls soil carbon efflux to the atmosphere in light of current climate uncertainty. The primary efflux of carbon from soil is soil respiration which is typically categorized into autotrophic and heterotrophic respiration. These two components...

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...
