Breeding habits, embryonic thermal requirements and embryonic and larval development of the Cascade frog, Rana cascadae Slater

Creator:: Sype, William E.
Abstract:: The breeding habits and embryonic thermal requirements of the Cascade frog of Oregon, Rana cascadae Slater, are described. The limits of temperature tolerance of the pre-feeding stages are from 6° to 27°C for embryos held at constant temperatures. However, for pre-feeding embryos exposed at different developmental stages for short durations...

Contributions to the plant ecology of the Oregon coastal sand dunes

Creator:: Wiedemann, Alfred M.
Abstract:: Sand dunes are found along the coasts of most of the large land masses of the world. Because of their proximity to man and his activities, the maritime sand dunes of Europe, particularly Germany, France, Holland and Scandinavia, have the longest history of stabilization activities and botanical investigation. There are...

Regulation by male-specific fruitless of neural circuitry used during courtship and copulation behavior in Drosophila melanogaster

Creator:: Latham, Kristin Lynn
Abstract:: Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...

Quaternary Landscape Evolution and the Surface Expression of Plume-Lithosphere Interactions in the Greater Yellowstone Area

Creator:: Guerrero, Eduardo Francisco
Abstract:: Numerous investigations demonstrate that mantle convective processes such as upwelling affect the surface topography of the overriding plate. The surface expression of mantle flow has been coined ‘transient topography’. Transient topography in the North American plate is thought to result from a mantle thermal anomaly beneath the Yellowstone volcanic center,...

Environmental Remote Sensing with Unmanned Aircraft Systems

Creator:: Burnett, Jonathan D.
Abstract:: Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....

Effects of prescribed cattle grazing on reforestation in Oregon's southern Cascades

Creator:: Karl, Michael G.
Abstract:: Reforesting harvested lands in southwestern Oregon has been difficult because of low rainfall, high evaporative demand, and competitive understory vegetation. Herbicides have been a preferred method to control competing vegetation but herbicide use on federal lands was curtailed in 1984. As a result, interest in livestock grazing as a vegetation...

Body Condition and Hormone Assessment of Eastern North Pacific Gray Whales (Eschrichtius robustus) and Associations with Ambient Noise

Creator:: Lemos, Leila S.
Abstract:: Anthropogenic activities have posed many threats to the oceans and marine life. Understanding how individuals are affected and physiologically respond to these threats is crucial and allows for management and conservation applications. I evaluated the overall health condition of a subpopulation of gray whales (Eschrichtius robustus) along the Oregon coast,...

Understory herb and shrub responses to root trenching, pre-commercial thinning, and canopy closure in Douglas-fir forest of the western Cascades, Oregon

Creator:: Lindh, Briana C.
Abstract:: This thesis examines factors limiting understory herb presence and flowering in young second-growth Douglas-fir (Pseudotsuga menziesii) forests on the west side of the Cascade Mountains, Oregon, USA. I studied the belowground effects of canopy trees on understory herbs and shrubs in old-growth forests using trenched plots from which tree roots...

An Assessment of the “Sweating Sickness” Affecting England During the Tudor Dynasty

Creator:: Wollert, Edwin Del
Abstract:: While historiography and interest in Tudor England at both the popular and specialist levels presents few signs of diminishing, there may nonetheless exist a sense that we have little left to learn about this period and its culture. A notable gap in our knowledge, however, remains regarding the mysterious disease...
