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...

Enhancing community college revenue sources by leveraging land resources

Creator:: Scott, Cheryl L.
Abstract:: Community colleges are experiencing a decline in state allocated funding. Traditionally, college administrators look for ways to cut expenditures and raise tuition and fees to make up for the shortfall. Using available land resources to generate a revenue stream may provide revenue for community colleges. The purpose of this study...

Neuronal and hormonal control of the vascular system of the marine mollusc, Aplysia californica

Creator:: Ligman, Scott H.
Abstract:: The vascular system of Aplysia californica is a simple visceromotor system with three main arteries innervated by a small pool of identified neurons. I used this system to study the functions of neuropeptide transmitters and their actions on neural and muscle tissues. A central finding of this study is that...

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...

A. W. N. Pugin and St. Augustine’s, Ramsgate : a nineteenth-century English gothic revivalist and his church

Creator:: Burton, Kathryn Lee
Abstract:: A. W. N. Pugin was a driving force in the Gothic Revival movement in England during the first half of the nineteenth century. He was an architect and a writer who expounded on the virtues of reviving Gothic architecture, not only for its reflection of the sacred mystery of ancient...

Indirect effects of fishing on predators and their prey

Creator:: Stallings, Christopher Derek
Abstract:: Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

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...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

Functional relationships among vegetation, nocturnal insects, and bats in riparian areas of the Oregon Coast Range

Creator:: Ober, Holly K.
Abstract:: Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...

Responses and relationships among Fusarium species, sweet corn, and western spotted cucumber beetles

Creator:: Miller, Nathan L. (Nathan Louis)
Abstract:: Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...
