Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...

Fingerprinting and genetic stability of Rubus using molecular markers

Creator:: Castillo, Nina Rosa F.
Abstract:: Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University.

Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

Analysis of Bacteroidales 16S rRNA gene sequences from a geographically isolated human population

Creator:: Petersen, Carolyn A.
Abstract:: Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...

Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:: Johnson, Katherine R.
Abstract:: Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

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...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Phenotypic evolution as a response to thermal ecology in the ferocious waterbug Abedus herberti (Hemiptera: Belostomatidae)

Creator:: Pelegrin, Arthur Lomis
Abstract:: Over 150 years ago, C. Bergmann observed a within-species pattern of increasing body size as elevation and latitude increased. Bergmann’s data came from numerous endothermic taxa, but the pattern has since been documented among numerous poikilotherms and invertebrates. The ferocious waterbug Abedus herberti Hidalgo (Hemiptera: Belostomatidae) lives in isolated populations...

Comparative foraging ecology of five species of Pacific seabirds : multi-scale analyses of marine habitat use

Creator:: Suryan, Robert
Abstract:: Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...
