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

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...

Behavioral ecology of marbled murrelets (Brachyramphus marmoratus) in forest and marine ecosystems of Oregon

Creator:: Jodice, Patrick G. R., 1961-
Abstract:: Marbled Murrelets (Brachyramphus marmoratus) are threatened seabirds that are prone to disturbance both at sea and at old-growth forest nesting areas. I examined murrelet behavior and activity patterns in forest and marine ecosystems of Oregon. Diving behavior was studied during the 1995 and 1996 breeding seasons and was compared to...

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...

Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:: Nielsen, Karina Johanna
Abstract:: The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...

Characteristics of northern flying squirrel and Townsend's chipmunk populations in second -and old-growth forests

Creator:: Rosenberg, Daniel K.
Resource Type:: Masters Thesis

Disaggregative and individual-tree growth models in theory and application

Creator:: Ritchie, Martin W.
Abstract:: Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...

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

Creator:: Rossbach, Kelly Ann
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...

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...
