Aspects of the autecology of the plethodontid salamander, Aneides ferreus (Cope)

Creator:: McKenzie, Donald Samuel
Abstract:: Laboratory experiments and simulated field conditions were utilized to gain a better understanding of the ecology of the clouded salamander. Animals collected in western Oregon were utilized for studies in habitat selection, where it was shown that there was a significant pattern of selection of litter types (rock, bark, and...

Studies on the interaction of polylysine with deoxyribonucleic acid

Creator:: McKenzie, Raymond Leslie
Abstract:: The interaction of polylysine with DNA may be divided into two separate phenomena: the primary interaction involved in formation of a well-defined complex, and secondary interactions leading to aggregation of these complexes. Most studies on the interaction of polylysine with DNA have used techniques which measure properties of the aggregated...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

Hemispheric processing of kinesthetically oriented spatial perception

Creator:: Nishizawa, Sho
Abstract:: Right cerebral hemispheric lateralization for spatial perception has been reported by using visual and tactile spatial tasks in brain-damaged patients, split-brain patients, and normal subjects. The main purpose of the present study was to investigate whether or not kinesthetic spatial perception was dominantly processed with the right cerebral hemisphere as...

A proteomic approach to 1,2-dichloroethane bioactivation and reaction with redox-active protein disulfide isomerase

Creator:: Kaetzel, Rhonda Sue
Abstract:: Protein disulfide isomerase (PDI), a member of the thioredoxin superfamily, contains two domains with significant sequence homology to the active sites in thioredoxin. PDI facilitates the folding of nascent proteins in the endoplasmic reticulum (ER), binds hormones and Ca²⁺, catalyzes the glutathione dependent reduction of dehydroascorbate, serves as a major...

Effects of enhanced mid-ultraviolet radiation (290-315 NM) on development and survival of Boreal toad (Bufo boreas boreas) tadpoles

Creator:: Worrest, Robert C., 1935-
Abstract:: More than 3700 fertilized toad eggs were used in a series of studies designed to determine the effects of UV-B radiation (290- 315 nm) on temporal developmental patterns, systematic development and viability prior to metamorphic climax. The eggs were exposed to radiation from either "white-light" fluorescent lamps (Vita-Lite, Duro-Test Corporation,...

A comparative study of temperate Chamaecyparis forests

Creator:: Hawk, Glenn M.
Abstract:: The objectives of this study include: (1) analysis of Chamaecyparis lawsoniana, C. taiwanensis, and C. formosensis forests including the structure, composition, and dynamics of plant communities and their environmental relationships; and (2) comparison of the temperate Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis on structural and successional...

Toxicity and in vitro metabolism of Senecio jacobaea pyrrolizidine alkaloids in the rat and mouse

Creator:: Ramsdell, Howard Scott
Abstract:: Senecio jacobaea (tansy ragwort) is a common weed in the Pacific Northwest that contains toxic pyrrolizidine alkaloids (PAs). Jacobine, the major PA in Senecio jacobaea, was incubated with rat liver microsomes and metabolites were isolated by high performance liquid chromatography (HPLC) and identified by mass spectrometric analysis. Metabolites included a...

Environmental contaminants in male river otters collected from Oregon and Washington, 1994-99, with reproductive organ hypoplasia observed in otter males

Creator:: Grove, Robert Allan
Abstract:: A large number of river otter (Lontra canadensis) males were collected from areas of high and low contaminant concentrations throughout western Oregon and Washington during the fall and winter of 1994-99. Few significant non-reproductive organ morphometric differences were found in the large series of male otters collected, except for adrenal...
