The use of high throughput molecular methods that allow for the study of bacterial communities in environmental samples is commonplace in microbial ecology. Until recently, fungal community ecology has
focused on isolation, collection of sporocarps, or collection of ectomycorrhizal roots. The techniques used to extract and amplify DNA from environmental...
Hypogymnia imshaugii is one of the most common, conspicuous and morphologically variable epiphytic lichens of the Pacific coastal states and provinces. The species varies greatly in morphology and chemistry, suggesting multiple closely related species or one or more phenotypically plastic species. We sought to determine whether additional ecologically meaningful species...
To gain a better understanding of how rapidly microbial communities respond to different magnitudes of perturbation that mimic minor or catastrophic disturbances.
Two montane sites in the western Cascade Mountains of Oregon with adjacent areas of forest and meadow vegetation were studied. A reciprocal transplant experiment evaluated both minor (soil...
This study compares arthropod biodiversity in areas infested with invasive cheatgrass Bromus tectorum with areas not infested. The goal of this project was to establish a baseline of the types of arthropods found in both habitats, discover if there is more diversity in either habitat and to find any patterns...
This literature review aims to discuss the safety and use of cannabidiol (CBD) products for dogs and cats. The most prominent issue with CBD products for pets is the limited amount of resources and information available to the veterinary community. Another consideration for the control of CBD on the market...
Systemic hypertension, a persistent elevation in systemic arterial blood pressure (BP), is a well-recognized disorder in cats. Failing to diagnose it accurately could lead to organ damage or unnecessary lifelong therapy. Doppler ultrasonic flow detectors are commonly used for indirect BP measurements in cats. However, whether the audible static from...
Billions of pounds of bisphenol A (BPA) are produced annually around the globe for the manufacture of numerous consumer products, including polycarbonate food and water containers, the protective resin linings of food cans, thermal printing paper, and dental fillings. BPA exposure during nervous system development has been associated with learning...
The problem of simple mathematical models of laminar natural convective
flow within a long vertical parallel-plate channels and circular tubes kept at
uniformly heated walls is revisited to seek a clear physical understanding of heat
transfer mechanisms. A series solution method to analyze the fully developed flow
and an integral...
This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties.
Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...
While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...
