Quaking aspen persistence in three Oregon landscapes

Creator:: Seager, S. Trent
Abstract:: Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...

Competition release and climate change effects on a moisture-demanding tree species in a dry system

Creator:: Seager, S. Trent
Abstract:: Climate change and the increase in meteorological drought have generated global concern over the persistence of ecosystems already in decline from decreased moisture. Evidence suggests dryland ecosystems have been more impacted by drought because of their tightly coupled growth-water relationships and high sensitivity to environmental shift. Removal of competing vegetation...

Una Perspectiva Etnica de la Sociedad Americana

Creator:: Perez, Alfred F.
Abstract:: The existence of the ethnic "barrios" (ghettos) across American society is proof of the legacy of racism, injustice and inequality in society today. In this thesis, the human experiences of Native, African, Mexican, and Asian people, are presented to contradict the notion that the "American Dream" is for all. In...

New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...

Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

Creator:: Thurman, Lindsey L.
Abstract:: Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...

It’s in Their Bones: Ecological Drivers of Kemp’s Ridley Sea Turtle (Lepidochelys kempii) Somatic Growth and Population Dynamics

Creator:: Ramirez, Matthew D.
Abstract:: Somatic growth variation manifests from the cumulative effects of a suite of biological, ecological, and environmental processes and can have profound effects on individual fitness and species population dynamics. As ectotherms whose growth dynamics are greatly influenced by environmental factors, sea turtles display considerable variation in somatic growth within and...

Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

Creator:: Sangsupan, Hathai A.
Abstract:: This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...

Utilizing a Lab-Based Minority Stress Paradigm for Experimental Research among Sexual and Gender Minority Groups: Application and Considerations

Creator:: Fahey, Kalina M. L.
Abstract:: Sexual and gender minority (SGM) samples report elevated rates of substance use and substance use disorder compared to their heterosexual and cisgender counterparts across a wide variety of substances (Connolly & Gilchrist, 2020; Krueger et al., 2020; Rice et al., 2019), in part due to the experience of minority stress....

Aquatic community responses to drought disturbance: experimental manipulations of top predator extinctions and stream drying

Creator:: Boersma, Kate S.
Abstract:: Although it is generally assumed that the intensifying abiotic environment is the primary effect of drought on aquatic organisms, drought-induced top predator extinctions may be an important underlying mechanism. I used manipulative experiments to disentangle the impacts of drying and top predator extinctions on arid-land aquatic invertebrate communities. I then...

Electro-optical characterization of SrS:Ce, SrS:Cu, and SrS:Cu,Ag alternating-current thin-film electroluminescent devices

Creator:: Grudzinsky, Arkady S.
Abstract:: The purpose of this thesis is to contribute to the understanding of SrS-based alternating-current thin-film electroluminescent (ACTFEL) device operation. Three main accomplishments serving this purpose are presented in this thesis. First, two new methods are developed for estimation of insulator capacitance in ACTFEL devices possessing a large amount of dynamic...
