Numerical Modeling of Lateral Erosion during Reservoir Drawdown

Creator:: Artruc, Tessa C.
Abstract:: Reservoir drawdown is a management technique increasingly used in maintenance of aging infrastructure, decommissioning dams, and to promote the flushing of fish and sediment to downstream reaches. Erosional processes in the reservoir may result in excessive delivery of sediment to downstream habitats and infrastructure, a critical long-term consideration. Typically, numerical...

Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

Management Applications of Remotely Sensed Dynamic Seascapes: Two Case Studies

Creator:: Klajbor, Willem C.
Abstract:: Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...

Exploring the biology and monitoring techniques of two economically impactful Chrysobothris species in Oregon hazelnuts

Creator:: Rudolph, Erica
Abstract:: Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...

Improving Honey Bee Health: Evaluating Efficacy and Safety of Oxalic Acid Vaporization Tactic for Varroa destructor Control and Understanding Factors Triggering European Foulbrood Disease

Creator:: Bozkus, Mustafa
Abstract:: Honey bees are vital for our food production and ecosystem due to their critical pollination services. The beekeepers in the United States and worldwide have reported significant colony losses for over fifteen years. Several stressors are implicated in these colony declines, including parasites, diseases, poor nutrition, and pesticide exposure. There...

Songbird Mobbing of Northern Pygmy-Owls: A Function of Risk Across Landscapes and Seasons

Creator:: Scott, Madeleine
Abstract:: The evolutionary arms race between predators and prey has led to a diverse set of interactions between species. Prey have developed an array of behaviors designed to reduce their risk of predation. Among those strategies, mobbing is a paradoxical behavior where prey actually approach predators, often in large multi-species flocks....

Determination of Mass Flow Rate through Plain Mesh Wick and Nano- Structured Mesh Wick for the Design of Thermal Compressor Systems

Creator:: Uwaoma, Ifeanyi A.
Abstract:: Wicking action refers to the movement of a liquid through a porous or a structured surface via capillary action. This phenomenon is affected by surface geometry, such as the wick thickness and pore size of the wick, as well as fluid properties, such as viscosity and surface tension of the...

Assessing Post-fire Tree and Understory Vegetation Response to a Mixed-severity Fire Gradient in the Klamath Mts., Oregon, USA

Creator:: Terzioglu, Cihat
Abstract:: Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...

Evaluating the Potential of Protein Supplements and Probiotics for Improving Honey Bee Health and Understanding Honey Bee Behaviors Related to Social Immunity

Creator:: Chapkin, Elissa R.
Abstract:: Managed honey bees (Apis mellifera) play a vital role in pollinating cultivated crops worldwide. Honey bee colony declines reported in the past two decades have been associated with stressors such as pests and diseases, pesticide exposure, and poor nutrition. In the wake of these colony declines, beekeepers have strived to...

Reburn Severity and Vegetation Recovery in Southwestern Oregon, USA

Creator:: Weber, Rebecca N.
Abstract:: The Klamath-Siskiyou Ecoregion of southwest Oregon and northern California is greatly departed from its historic, mixed-severity fire regime. This departure manifests in larger wildfires, greater proportions of high burn severity within wildfire perimeters, and decreased diversity of post-fire vegetation successional stages and trajectories across the landscape compared to historical norms....
