Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:: Miller, Todd William
Abstract:: The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

Spatial and age class analysis of managed western juniper (Juniperus occidentalis) woodlands in central Oregon

Creator:: Zophy, Kelley T.
Abstract:: Juniper is a native species to Oregon and confers ecological benefits to wildlife when it is at savannah and transitional densities. Its range and extent have fluctuated with climatic change, but the current range expansion is unprecedented in its extent. The range expansion has been associated with the degradation of...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

"As a family we are going to be here" : Mexican immigrant mothers' experiences with parenting in distinct community contexts

Creator:: Feeney, Sarah L.
Abstract:: Recent demographic studies have revealed a greater diversity in settlement patterns among Mexican immigrant families resulting in rapidly climbing populations of immigrants in new areas of the country, particularly in rural areas, while growth in established destinations has slowed. Host communities play an important role in families' acculturation processes and...

Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

Creator:: Yarger, David J.
Abstract:: Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

The experiences of Asian American females seeking vice president and president positions in community colleges : A view of the barriers and facilitators

Creator:: Somer, Marcia G.
Abstract:: This qualitative narrative inquiry study explored the experiences and perspectives of five Asian American females who have sought presidencies and/or vice presidencies in community colleges. All five of the participants are currently either a president or vice president in community colleges. This study found nine themes that capture the barriers...

Sesame oil increases plasma γ-tocopherol and inhibits γ-tocopherol metabolism in humans

Creator:: Lee, Sangeun
Abstract:: In rats, sesame lignans increase plasma γ-tocopherol concentrations and inhibit γ-tocopherol degradation to its metabolite γ-carboxyethylhydroxychroman (γ-CEHC). To test if sesame lignan consumption inhibits γ- tocopherol metabolism in humans, muffins prepared with either corn oil (control) or sesame oil and an equimolar mixture of deuterium labeled d6-α- and d2-γ- tocopheryl...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...
