Post-eruption recovery and secondary production of grazing insects in two streams near Mt. St. Helens

Creator:: Meyerhoff, Richard Dietrich
Abstract:: The eruption of Mt. St. Helens provided the opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...

Plasma carotenoids and retinol and dietary intake : association with in situ and invasive cervical carcinomas in Bangkok, Thailand

Creator:: Kaunda, Jean R.
Abstract:: There is a strong evidence that human papillomavirus (HPV) is the key causative agent of cervical cancer. However, the majority of women who are exposed to the oncogenic HPV do not develop invasive cervical cancer, suggesting that other factors could play a role in the cause and progression of cervical...

Luminescent sulfides and solution-deposited oxide thin films

Creator:: Anderson, Jeremy T.
Abstract:: Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

Multi-scale relationships between aspen and birds in the northern Yellowstone ecosystem

Creator:: Hollenbeck, Jeff P., 1967-
Abstract:: I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by...

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...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...

Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

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...
