Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...
The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
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...

My thesis, entitled “The Clerk’s Tale: Literal Monstrosities and Allegorical Problems,” argues that Chaucer’s Clerk is engaging both sides of a binary system. The Clerk has situated himself in a precarious position between two major schools of thought in the medieval culture, Franciscan and Dominican; the former promotes the will...
The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
The United States Fish and Wildlife Service currently uses fire as a management tool to improve Greater Sage Grouse (Centrocercus urophasianus Bonaparte) nesting and brood-rearing habitat at Hart Mountain National Antelope Refuge (HMNAR) in S.E. Oregon. Previous studies at HMNAR revealed use of burned areas by sage grouse throughout the...
Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...
Archival information about fish and water in the Umpqua Basin can be found in reports housed in disparate locations (e.g., offices of various State and Federal agencies and local organizations). A comprehensive bibliography of grey literature, important or uncataloged reports, and published reports is one means of recording what research...

The ecology of netleaf hackberry (Celtis reticulata Torr.) is poorly known
throughout its broad western range. To gain some understanding of the species' basic
ecology, three components of its life history were studied. First, seed germination
requirements were analyzed under laboratory conditions. Second, hackberry population
dynamics were evaluated from tree...
Statistically, travel by air is one of the safest forms of transportation. Yet we
continue to experience aviation tragedies. Do we fully understand flight safety or is
there another way of looking at the problem? In this work a new way of approaching
the question of flight safety is developed,...
In many schools, drugs, vandalism, assaults,
thefts, and violence against both students and teachers
have destroyed the orderly atmosphere needed for teaching
and learning. While juvenile criminal behavior,
both in school and elsewhere, is caused by a large and
complex set of sociological and psychological conditions,
there is evidence that...

elementary schools in Oregon which had distinctly different
socio-economic populations.
The tests used for...
Vibriosis caused by the bacterial pathogen Vibrio tubiashii is one of several factors contributing to mass larval mortalities of the Pacific oyster (Crassostrea gigas) in Pacific Northwest shellfish hatcheries in recent years. Genetically improved strains of the Pacific oyster resistant to V. tubiashii would be highly desirable. This study investigates...
In the last three decades we have learned a great deal about microbes in subsurface environments. Once, these habitats were rarely examined, perhaps because so much of the life that we are concerned with exists at the surface and seems to pace its metabolic and evolutionary rhythms with the overt...
Many hazardous locations exist on our local and street highway
systems. Such hazards contribute to the frequency and severity of
traffic accidents. The elimination and mitigation of the hazards
reduces accident frequency and severity, as measured by the number of
fatalities, injuries and property damage resulting from the accidents.
The...
Background: The identification of the loci and specific alleles underlying variation in quantitative traits is an important goal for evolutionary biologists and breeders. Despite major advancements in genomics technology, moving from QTL to causal alleles remains a major challenge in genetics research. Near-isogenic lines are the ideal raw material for...
Literature is recorded thought or knowledge; the aggregate of books and other publications, in either an unlimited or a limited sense; the collective body of literary productions in general, or within a particular sphere,
period, country or language. In a restricted sense, the

Landscape fire succession models (LFSMs) predict spatially–explicit interactions between vegetation
succession and disturbance, but these models have yet to fully integrate ungulate herbivory as a driver of
their processes. We modified a complex LFSM, FireBGCv2, to include a multi-species herbivory module,
GrazeBGC. The system is novel in that it explicitly...
Coral reproduction is vital to the persistence of coral reefs. Decades of ecological studies have correlated environmental variables, such as temperature and light, to the timing of reproduction in anthozoan cnidarians, including corals and sea anemones. However, elevated temperatures associated with climate change impair reproductive success and threaten the resilience...
Nanotechnology is of increasing significance. Curation of nanomaterial data into electronic databases offers opportunities to better understand and predict nanomaterials’ behaviour. This supports innovation in, and regulation of, nanotechnology. It is commonly understood that curated data need to be sufficiently complete and of sufficient quality to serve their intended purpose....
The Curiosity rover has analyzed various detrital sedimentary rocks at Gale Crater, among which fluvial and lacustrine rocks are predominant. Conglomerates correspond both to the coarsest sediments analyzed and the least modified by chemical alteration, enabling us to link their chemistry to that of source rocks on the Gale Crater...
The Santo Tomas University Internment Camp Podcast tells the story of a prison camp run by the Japanese in the Philippines during World War Two, told through a scrapbook created by two internees named Frank and Mildred Miles.

Every year thousands of people are killed or injured in work zone crashes in the US due to excessive speed, distraction, inattentiveness, low visibility, and other factors. Roadway construction and maintenance operations often occur at night when the traffic volume is low, creating less congestion and delay to the traffic....
Most of today’s Internet of Things (IoT) applications assume that data will be moved offdevices into centralized cloud platforms. While existing IoT systems leverage cloud-based analytics for meaningful data reasoning, the assumption that data should always be moved off the devices is problematic. The amount of data to be moved...
This thesis uses a series of non-fiction vignettes to explore objects, agencies, and networks, applying theories of rhetoric and composition directly to experience and vise versa. Focusing on agency--as understood through sociology's actor-networks, post- humanism’s Object Orientated Ontology, and Ecocriticism's ecological approach--I look at events, landscapes, and partnerships that have...
Mary Collins composed the award-winning book American Idle in 2009 after her recovery from an awful bicycle accident. This bicycle accident inspired Mary Collins to take a trip of discovery. Mary Collins visited historical locations to see changes in peoples’ physical activity over time. Collins interviewed individuals whose professions varied...
River impoundment by dams, along with other human driven changes, has threatened the health of riparian forests in the northern Great Plains for much of the last century. Two major concerns in the region are the impediment of natural recruitment of plains cottonwood (Populus deltoides Marsh. subsp. monilifera (Ait.) Eckenw.)...
This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and...
Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...
Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...
This thesis invokes Black Jesus as an abstract figure in two seemingly disparate early twentieth century American novels and, in doing so, intervenes in ongoing debates about the ethical capacities of literature as means of grappling with difference. The Christ figure is a literary trope of waning importance in contemporary...
Recent statistics suggest that the construction industry continues to experience poor project performance. Specifically, construction productivity has witnessed a meager annual growth of 1% over the past 20 years while the industry constantly records both a high number of fatalities and a high fatality rates relative to other industries. The...
Cell membranes act as barriers against unwanted movement of ions and biomolecules and are complex surfaces littered with protein channels, ion channels, cholesterol, and a myriad of different proteins. While this surface is extremely well studied, there is still much we do not know. The work in this dissertation demonstrates...
Night is an extraordinary resource. Unlike air, water, or soil, nighttime is a spatio-temporal phenomenon, which leads to many crucial roles. It provides refuge to wildlife species, triggers hormonal and behavioral responses among a wide variety of organisms, and serves as an essential migratory backdrop for species that navigate by...
Structure-property relationships have always underpinned the field of solid state chemistry; dependable structural descriptions are integral to understanding and controlling the physical properties of inorganic compounds old and new. While a handful of crystal structures are celebrated for their versatility, flexibility, and functionality, the existence of more exotic structures is...
Marine sediments are vast sources and reservoirs of methane, a potent greenhouse gas. Most of this methane is anaerobically oxidized by archaea before it can reach the overlying ocean, though the efficiency of this process often depends on methane fluxes and mechanisms of fluid transport. Anaerobic methanotrophic archaea, or ANME,...
