Lamb production differences of bighorn sheep on Hart Mountain, Oregon

Creator:: Cottam, Douglas F.
Resource Type:: Masters Thesis

Transmission of the chewing louse, Damalinia (Cervicola) sp., from Columbian black-tailed deer (Odocoileus hemionus columbianus) to Rocky Mountain mule deer (Odocoileus hemionus hemionus) and its role in deer hair-loss syndrome.

Creator:: Robison, Jason A.
Abstract:: The potential for Rocky Mountain mule deer (Odocoileus hemionus hemionus) to host exotic chewing lice (Damalinia (Cervicola) sp.) believed to cause deer hair loss syndrome in Columbian black-tailed deer (Odocoileus hemionus columbianus), was investigated in captive deer held in pens at E.E. Wilson Wildlife Area, Corvallis, Oregon from March 2004...

The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:: Johnson, Dustin D.
Abstract:: Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...

The chemistry and device applications of amorphous thin-film interfaces

Creator:: Knutson, Christopher C.
Abstract:: Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

Spawning, larval recruitment, and early life survival of Pacific lampreys in the South Fork Coquille River, Oregon

Creator:: Brumo, Abel F.
Abstract:: Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...

Taxonomic analyses of the Oregon chub, Oregonichthys crameri

Creator:: Bills, Debra T.
Abstract:: The Oregon chub. Oregonichthys crameri. one of Oregon's endemic freshwater fishes. is restricted to the Willamette and Umpqua rivers and their tributaries. Specimens from the two rivers have traditionally been considered the same species. The goal of this study was to re-examine that assumption and determine if the Willamette Oregon...

Determination of fluorinated alkyl substances in aqueous systems

Creator:: Schultz, Melissa M.
Abstract:: Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

Patterns of temporal and spatial habitat use by sympatric speckled dace (Rhinichthys osculus) and longnose dace (R. cataractae) in an Oregon Cascades stream

Creator:: Dodge, Karen L.
Abstract:: Microhabitat use by adult speckled dace (Rhinichthys osculus), adult longnose dace (R. cataractae), and juvenile dace (R. spp.) was investigated during the summer of 1992 in an Oregon Cascades stream. Selected areas were snorkeled day and night in order to evaluate differential use of habitat resources both temporally and spatially....

Species identification of Klamath Basin suckers (Pisces : Catostomidae) and an assessment of hybridization using anonymous nuclear loci

Creator:: Wagman, David Wolfe
Abstract:: Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...

Gas-phase fragmentation chemistry of protonated peptide ions

Creator:: Bythell, Benjamin James
Abstract:: The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...
