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...

The stability of pelargonidin-based anthocyanins in natural and model systems

Creator:: Garzon, G. Astrid
Abstract:: Pelargonidin 3-glucoside (pgd 3-glu), pelargonidin 3-sophoroside (pgd 3-soph), and pelargonidin 3-sophoroside 5-glucoside acylated with cinnamic and malonic acids (acyl-pgd 3-soph 5-glu) were extracted from strawberries (Fragaria anannassa cv, Totem), nasturtium flowers (Tropaeolum majus), and radish peel (Raphanus sativus L. cv, fuego), respectively. Their stability was studied in natural and model...

F-tests in partially balanced and unbalanced mixed linear models

Creator:: Utlaut, Theresa L.
Abstract:: This dissertation considers two approaches for testing hypotheses in unbalanced mixed linear models. The first approach is to construct a design with some type of structure or "partial" balance, so that some of the optimal properties of a completely balanced design hold. It is shown that for a particular type...

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...

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...

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...

Delineating pattern and process in tropical lowland : mealy parrot migration dynamics as a guide for regional conservation planning

Creator:: Bjork, Robin D.
Abstract:: Most reserves fail to capture the habitat heterogeneity necessary to maintain viable populations of wide-ranging species. Methods to determine defensible dimensions of reserves and reserve networks are needed. The primary goal of this study was to develop such methods for lowland tropical forests by examining habitat- and spatial-use patterns of...

Ecology of populations of Van Dyke's salamanders in the Cascade Range of Washington State

Creator:: McIntyre, Aimee P.
Abstract:: The Van Dyke's salamander (Plethodon vandyke,) is a rare species endemic to Washington State. It has been found in cool moist microhabitats along streams, splash zones of waterfalls, and headwater seeps. We explored the association of the Van Dyke's salamander with hydrologic condition, geomorphology, disturbance characteristics, and vegetation structure in...

Nest-site selection in cooperatively breeding Pohnpei Micronesian Kingfishers (Halcyon cinnamomina reichenbachii) : does nest-site abundance limit reproductive opportunities?

Creator:: Kesler, Dylan C.
Abstract:: Despite their inherent importance and utility as ecological examples, island species are among the most endangered and least studied groups. Guam Micronesian Kingfishers (Halcyon cinnamomina cinnamomina) exemplify the plight of insular biota as a critically endangered and understudied island bird that went extinct in the wild before they could be...

Spatial structure of the physical and biological distributions across the Antarctic Polar Front in austral spring and summer

Creator:: Howard, Cidney
Abstract:: Mesoscale surveys to examine the relationship between the physical processes and biological response along the Antarctic Polar Front (PF) were conducted as part of the US JGOFS Southern Ocean Program during austral spring and summer 1997/98. Multiple crossings of the PF near 170° W, using a towed undulating instrument, provided...
