Accumulation and effects of 4-nonylphenol in chinook salmon fry and their estuarine amphipod prey

Creator:: Hecht, Scott A.
Abstract:: 4-nonylphenol (NP), a surfactant degradation product, is an unregulated, ubiquitous aquatic contaminant and endocrine disruptor, for which aquatic life criteria are currently under development by U.S. EPA. The effects of NP on estuarine amphipods and chinook salmon fry were investigated, and this dissertation reports research into the impacts of NP...

Physiological and organism level endpoints in the beetle pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal pollution

Creator:: Stone, David
Abstract:: Pollutant body burdens, ability to tolerate supplementary stressors, and biomarkers of physiological stress were investigated in the ground beetle, Pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal contamination in Poland. The central question was to determine if beetles inhabiting polluted habitats incurred costs compared with beetles in less...

Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:: Johnson, Katherine R.
Abstract:: Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

Enhancing the predatory potential of hoverflies on aphids in Oregon broccoli fields with floral resources

Creator:: Ambrosino, Mario D.
Abstract:: Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...

Seasonal movement, residency, and migration patterns of Wilson's Snipe (Gallinago delicata) across the annual cycle in the Willamette Valley of Oregon.

Creator:: Cline, Brittany B.
Abstract:: Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...

Selenium and trace metal accumulation in detrital-benthic food webs of lotic and lentic wetlands, Utah, USA

Creator:: Hillwalker, Wendy E.
Abstract:: Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...

Susceptibility of riparian soil invertebrates to the herbicide triclopyr

Creator:: Moran, Patrick (Patrick William)
Abstract:: Riparian zones of Pacific Northwest forests have high species diversity and abundance and act as an important interface between the aquatic and terrestrial ecosystems. In addition, riparian zones comprise a significant portion of the total buffer zone established during commercial forest production to protect aquatic ecosystems from adjacent management activities....

Negotiating conflicted climates : the experiences of transgender students attending women's colleges

Creator:: Jones, Whitney K.
Abstract:: The conversation regarding transgender students in the context of women's colleges is inherently complicated due to the binary gender system that the existence of women's colleges reinforce. The primary goal of this phenomenological research was to examine the lived experiences of transgender college students at U.S. women's colleges. Because the...

Shifting Rural Quantification Towards Study of Health Disparities: Applications in Statistical and Spatial Analysis of Rural Colorectal Cancer

Creator:: Buchalter, Robert Blake
Abstract:: Quantitative measurement of the urban-rural continuum for examination of U.S. rural health disparities is a relatively new research area, where only a handful of studies have investigated health disparities using quantitative rural measures and even fewer have attempted to integrate health variables within said measures. Most U.S. rural health disparity...

Can you see me?

Creator:: Wyckoff, Elizabeth
Abstract:: In Can You See Me?, a collection of nine short stories, Elizabeth Wyckoff explores the conflicting desires of young women who long for connection, but struggle to find the balance between concealing and revealing themselves. The female protagonists in these stories simultaneously yearn to be seen, recognized, and acknowledged; and...
