Using an indicator model to rank relative stock status of minor West Coast rockfish species

Creator:: Miller, Stacey D.
Abstract:: Quantitative assessments of many West coast rockfish stocks of both major and minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...

Small broomrape (Orobanche minor) management using wheat (Triticum aestivum) as a false host

Creator:: Al-thahabi, Salam A.
Abstract:: Small broomrape (Orobanche minor) is an obligate, chlorophyll-lacking parasite that parasitizes red clover (Trifolium pratense) roots. This study was conducted to develop and implement an integrated, biologically based control program for small broomrape by using wheat as a false host to reduce the soil seed bank. The relationship between temperature...

Culture built upon the land : a predictive model of nineteenth-century Canadien/Métis farmsteads.

Creator:: Hebert, James Michael
Abstract:: The objective of this thesis is to provide a predictive model for the archaeological investigation of the first farmsteads in the Pacific Northwest, established in the early- and mid-nineteenth century by Canadien and Métis families retiring from their service in the fur trade. Past studies of this population have either...

Mantle melting and heterogeneity along mid-ocean ridges : insight from basalt geochemistry along axial depth and morphologic gradients for intermediate spreading rate systems

Creator:: Russo, Christopher J.
Abstract:: This investigation focuses on gaining a better understanding of the complex relationship between melt generation, source variability and mid-ocean ridge morphology. The approach adopted here uses a variety of geochemical techniques to evaluate the ability of 'global' models to predict regional scale geochemical variability associated with axial depth and axial...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Phenotypic evolution as a response to thermal ecology in the ferocious waterbug Abedus herberti (Hemiptera: Belostomatidae)

Creator:: Pelegrin, Arthur Lomis
Abstract:: Over 150 years ago, C. Bergmann observed a within-species pattern of increasing body size as elevation and latitude increased. Bergmann’s data came from numerous endothermic taxa, but the pattern has since been documented among numerous poikilotherms and invertebrates. The ferocious waterbug Abedus herberti Hidalgo (Hemiptera: Belostomatidae) lives in isolated populations...

Deep ultraviolet solid-state laser development

Creator:: Dutton, David A. (David Adam)
Abstract:: There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

Geochemical and helium isotopic variability within the Lau Basin

Creator:: Goddard, Charlotte Ives
Abstract:: This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...

Modeling the energetics of Steller sea lions (Eumetopias jubatus) along the Oregon Coast

Creator:: Malavear, Maria Yolanda Garcia
Abstract:: A dynamic bioenergetic model for Steller sea lions (Eumetopias jubatus) was built using the STELLA simulation modeling system. The model is intended as an aid for the exploration of ecological questions regarding growth and survival of immature Steller sea lions (ages 1-3) living along the Oregon coast under different nutritional...

Analysis of dredge tailings pile patterns : applications for historical archaeological research

Creator:: Purdy, Sarah E.
Abstract:: For centuries humans have been searching for precious metals. The search for gold has greatly changed the landscape of the American West, beginning in the 1850s and continuing today. Various gold rushes around the country created mining colonies in remote areas, thereby connecting the frontier with the rest of America...
