Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Early competitive environments differentially influence stress axis responses in sympatric, ecologically similar songbirds

Creator:: Hardt, Braelei M.
Abstract:: 1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...

Evaluating the response of bees to visual attractants in resource-poor environments

Creator:: Parvin, Lucas
Abstract:: Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

Thermal conductivity measurements of amorphous thin films on silicon via the 3ω method

Creator:: Wiedle, River Alan
Abstract:: Thermal transport properties of a material are often difficult to measure, especially for thin films, but they are important for materials that have applications in modern devices, such as nano-scale electronics, thermoelectrics, and thermally resistive coatings. In this thesis, we describe an apparatus developed to measure the thermal conductivity of...

Cool hideaways: use of temperature refuges by juvenile coho salmon in the West Fork Smith River

Creator:: Raskauskas, Nancy
Abstract:: The West Fork Smith River, a 69 km2 watershed in the Coast Range of Oregon, is prone to short periods of very high water temperature in mid-summer due to a combination of human and natural influences. In the summers of 2003 and 2004 more than 400 juvenile coho salmon regularly...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Assessing Annelid Habitat Suitability in the Lower Klamath River Basin

Creator:: Corrigan, Rory
Abstract:: This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...

Evaluating the mixed species feeding opportunities provided by foraging humpback whales (Megaptera novaeangliae) across ocean ecosystems

Creator:: Ellett, Lindsey G.
Abstract:: Group foraging occurs across many ecosystems and taxa, and benefits some or all individuals in the group by optimizing feeding efficiency. The beater theory describes when individual “beaters” benefit other group members by herding prey into more accessible areas. Humpback whales feed on a variety of small patchy prey, and...

Visualizing Rivers: An Interactive Map of United States Water Sheds

Creator:: Burk, Bailey K.
Abstract:: An interactive map of important watersheds in the United States was created for use as a teaching tool in an estuarine ecology class. Figures and explanations of important factors influencing river ecology were created using data downloaded from the U.S. Geologic Survey. This interface serves as a visualization of biological,...

A Tool for Estimating the Health Benefits from Outdoor Recreation in Oregon

Creator:: Dunn, Tara E.
Abstract:: The purpose of this project is to modify the Transportation Options Health Impact Estimator (TO Estimator) tool to quantify the health impacts of outdoor recreation in Oregon. The TO Estimator tool uses the Integrated Transportation and Health Impact Model (ITHIM) to quantitatively estimate the hypothetical health impacts of transportation mode...
