Effects of host resistance on Mycosphaerella graminicola populations

Creator:: Cowger, Christina
Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...

Dependence of oxygen vacancy concentration in zirconia on processing parameters and reducing conditions

Creator:: Lee, Theresa A.
Abstract:: ¹¹¹In/Cd perturbed angular correlation (PAC) gamma spectroscopy was used to study the point defect thermodynamics of tetragonal zirconia (t-zirconia). PAC can be used to measure, among other things, oxygen vacancy defect concentrations in t-zirconia. Higher than expected concentrations of oxygen vacancies in undoped samples were found using PAC. It was...

Foraging ecology, colony attendance, and chick provisioning of Caspian terns (Sterna caspia) in the Columbia River Estuary

Creator:: Anderson, Scott K.
Abstract:: This study was designed to enhance understanding of factors influencing foraging distribution, diet composition, and overall reproductive success of Caspian terns (Sterna caspia) nesting on East Sand Island in the Columbia River estuary. This colony of nearly 10,000 breeding pairs is of concern to regional resource managers because Caspian terns...

Neuroendocrine mechanisms that regulate context-dependent behavioral responses to acute stress

Creator:: Coddington, Emma
Abstract:: In nature, animals survive threats by responding physiologically and behaviorally in ways that are appropriate to the situation. Which responses are appropriate depend on the animals' surroundings and current physiological and behavioral state. This dissertation investigated the neuroendocrine mechanisms that control context-dependent behavioral responses to stress by focusing on the...

Habitat use by snag-associated species : a bibliography for species occurring in Oregon and Washington

Creator:: Weikel, Jennifer M., Hayes, John P. (John Parker), and Oregon State University. Forest Research Laboratory
Abstract:: Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...
