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...

Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Molecular investigation of the cnidarian-dinoflagellate symbiosis and the identification of genes differentially expressed during bleaching in the coral Montipora capitata

Creator:: Hauck, Laura L.
Abstract:: Cnidarians, such as anemones and corals, engage in an intracellular symbiosis with photosynthetic dinoflagellates. Corals form both the trophic and structural foundation of reef ecosystems. Despite their environmental importance, little is known about the molecular basis of this symbiosis. In this dissertation we explored the cnidariandinoflagellate symbiosis from two perspectives:...

The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

The implementation year of shared governance at a Vanguard community college

Creator:: Lanning, Patrick M.
Abstract:: College governance is a function of structure and of how people act within that structure. Organizational strategies no longer identify administrations as monopolies that possess all of the good ideas. Recent organizational management approaches to governance promote inclusiveness in decision-making and are at odds with the community college's historical structures,...

Salt marsh reestablishment following dike breaching in the Salmon River estuary, Oregon

Creator:: Mitchell, Diane Lynne
Abstract:: A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...

Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

Distribution of Euphausiacea and Copepoda off Oregon in relation to oceanographic conditions

Creator:: Hebard, James Frank
Abstract:: Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...

Regions to streams : spatial and temporal variation in stream occupancy patterns of coho salmon (Oncorhynchus kisutch) on the Oregon coast

Creator:: Flitcroft, Rebecca L.
Abstract:: Aquatic ecological investigation is expanding to encompass considerations of multiple scales across large landscapes. Much of the analysis included in this work focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on the Oregon coast. Coho salmon were chosen for an investigation of spatial scales, network connections, and life...

Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...
