Early succession in beds of the red alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae) : alternate pathways

Creator:: Olson, Annette M.
Abstract:: Multiple successional sequences have been observed following disturbance in communities on marine hard substrata. Observations of the turf-forming alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae), suggest that I. cornucopiae may assume its dominance by its ability to vegetatively pre-empt space. High limpet densities in the natural community, suggest that I....

Bird and rodent nesting in excavated cavities in Pinon-juniper woodland, southeastern Colorado

Creator:: Youkey, Donald E.
Abstract:: I studied bird and rodent nesting in woodpecker-excavated cavities in pifion-juniper (Pinus edulis-Juniperus monosperma) (P-J) woodland in southeastern Colorado during the spring and summer of 1987 and 1988. Two related investigations were conducted: one described characteristics of habitat used by birds and rodents nesting in woodpecker-excavated cavities and the other...

Satellite monitored dive characteristics of the northern right whale, Eubalaena glacialis

Creator:: Nieukirk, Sharon L.
Abstract:: The western North Atlantic population of the northern right whale (Eubalaena glacialis) was severely depleted by whaling over the last century. Despite over fifty years of protection, fewer than four hundred individuals are believed to exist in the North Atlantic. Relatively little is known about the diving behavior, respiratory physiology,...

Assessment of ground water recharge and quality under agricultural production in Lane County, Oregon

Creator:: Shelby, Patrick M.
Abstract:: Assessment of the environmental impacts of an agricultural production system requires information on both soil water quality and solute flux. Passive Capillary Samplers (PCAPS), which sample water from the vadose zone using fiber glass wicks, have shown potential to provide both flux and solute concentration in unsaturated zone sampling but...

Distinguishing inshore and offshore communities of bottlenose dolphins (Tursiops truncatus) near Grand Bahama Island, Bahamas

Resource Type:: Masters Thesis

Effects of jet aircraft overflights and other potential disturbances on behavioral responses and productivity of nesting peregrine falcons

Creator:: Nordmeyer, Dana L.
Abstract:: In order to examine the potential impact of military jet overflights and other disturbances on productivity of peregrine falcons (Falco peregrinus), we observed behavioral reactions of peregrines to disturbances at nests along the Tanana River, Alaska during the 1995-1997 breeding seasons. Military jets conducted low-altitude flights over a sample of...

Paleomagnetism of Jurassic plutons in the central Klamath Mountains, southern Oregon and northern California

Creator:: Schultz, Karin L.
Abstract:: An understanding of the tectonic history of the Klamath Mountains is crucial for a valid paleogeographic reconstruction of the Pacific Northwest. However, prior to this study there were very few paleomagnetic (PM) data from the Klamath Mountains (KN), which resulted in conflicting interpretations about the role of the KM province...

Annual cycles of organic matter and phytoplankton attributes in the Columbia and Willamette Rivers, with reference to the Columbia River Estuary

Creator:: Sullivan, Barbara Elaine
Resource Type:: Masters Thesis

Alternative methods of raw product valuation for agricultural cooperatives : a forecasting approach

Creator:: Wiese, Arthur Michael
Abstract:: Raw product value of vegetables for processing in the Northwest used to be established by a competitive market involving proprietary processors and growers. Due to the relocation of proprietary processors to the Midwest, this competitive market has eroded forcing cooperative processors to seek other means to set raw product values....

Toward a new methodology for estimating the marginal social rate of return to public investments in higher education

Creator:: Lewandrowski, Jan
Abstract:: The United States invests tens of billions of dollars in higher education each year. This had led many researchers to estimate the marginal and average rates of return to these expenditures. Past works, however, have been partial in scope. That is, they have counted only the benefits of higher education...

Environmental variables as predictors of fish assemblages in the Tillamook Basin, Oregon

Creator:: Rose, Cathleen E.
Abstract:: The Tillamook and Kilchis subbasins of the Tillamook Bay watershed (Oregon Coast Range) have differences in geology and land use history and, therefore, varied environmental conditions that could affect fish assemblages. Fifty-two randomly selected wadeable stream reaches in these two subbasins were surveyed for stream habitat and fish assemblage composition...

Foraging ecology of migrant waterbirds, Lake Abert, Oregon

Creator:: Boula, Kathryn Marcile
Abstract:: Seven species of water-dependent birds (northern phalarope, Phalaropus lobatus; American avocet, Recurvirostra americana; Wilson's phalarope, P. tricolor; eared grebe, Podiceps nigricollis; ring-billed gull Larus delawarensis; California gull, L. californicus; and northern shoveler, Anas clypeata) were studied during the fall migrations of 1982 and 1983 to determine the diets and foraging...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

The range expansion of the northern barred owl : an evaluation of the impact on spotted owls

Creator:: Kelly, Elizabeth G.
Abstract:: Since their range expansion into the Pacific Northwest, anecdotal evidence suggests that northern barred owls (Strix varia varia) may be displacing northern spotted owls (Strix occidentalis caurina). My objectives were to characterize barred owl distribution and population increase in Oregon, investigate spotted owl territory performance before and after barred owl...
