Habitat use, movement, and life history variation of coastal cutthroat trout, Oncorhynchus clarkii clarkii, in the Salmon River estuary, Oregon

Creator:: Krentz, Lisa K.
Abstract:: Anadromous coastal cutthroat trout Oncorhynchus clarkii clarkii may be highly dependent on estuaries, passing through them multiple times during their lifetime. However, few studies have investigated estuarine use by coastal cutthroat trout and it is often thought that estuaries serve primarily as migration corridors rather than rearing areas. We used...

Predators associated with hemlock woolly adelgid (Hemiptera: Adelgidae) infested western hemlock in the Pacific Northwest.

Creator:: Kohler, Glenn R.
Abstract:: The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western...

Seed dormancy in domesticated and wild sunflowers (Helianthus annuus L.) :types, longevity and QTL discovery

Creator:: Brunick, Robert L.
Abstract:: Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to...

Environmental complex mixtures modify benzo[a]pyrene and dibenzo[a,l]pyrene-induced carcinogenesis

Creator:: Courter, Lauren A.
Abstract:: Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...

Genetic resistance to white mold (Sclerotinia sclerotiorum (Lib.) De Bary) in scarlet runner beans (Phaseolus coccineus L.)

Creator:: Gilmore, Barbara S.
Abstract:: White mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a destructive yield-limiting disease of common bean (Phaseolus vulgaris L.). Genetic resistance to this pathogen is limited in common bean. Identification of high levels of partial physiological resistance in a genetically cross compatible species, Phaseolus coccineus, is advisable. The objectives...

Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

Creator:: Tamayose, Joy
Abstract:: Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

Seismotectonics of the Himalayas and the Tibetan Plateau : moment tensoranalysis of regional seismograms

Creator:: Baur, Jan R.
Abstract:: This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world’s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were...

Making the connection to K-12 education for noncollege-bound students : the voices of students and workers address school experiences and workforce preparation

Creator:: Campbell, Willa M.
Abstract:: This study examined the relationships between business, education, and the economy, and specifically addressed the significant impact that business has had on education and educational policy. A large amount of research exists on the history of school reform and the development of educational policy, but none of the research examined...

Comparison of MODIS binary and fractional snow cover mapping techniques in the Himalayan Region, Nepal

Creator:: Tuladhar, Preeti
Abstract:: Satellite remote sensing is an effective tool for mapping snow covered area. However, complex terrain and heterogeneous land cover, due to vegetation and patchy snow cover, present challenges to snow cover mapping. This research compares two techniques for mapping snow covered area: binary and enhanced fractional snow cover mapping techniques....

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...
