Exploring the Differences between Lagrangian and Eulerian Reference Frames for Stream Temperature Data

Creator:: Egan, Fey Frentress
Abstract:: Stream temperature research relies on reference frames in which to project data. An important decision in the project design is which frame of reference to use. This aspect of research planning is not always given the consideration of thought that would lead to the best decision. In this thesis, two...

FishXing: evaluation of fish passage culvert model and comparision with Oregon Department of Forestry's compliance with fish passage and peak flow requirements at stream crossings

Creator:: Morrissette, Brett A.
Abstract:: FishXing (fish crossing), a computer aided stream crossing culvert model designed to analyze fish passage through culverts was compared with results of an Oregon Department of Forestry fish passage monitoring report. FishXing was created at Humboldt State University through sponsorship from the US Forest Service, USDA, Stream Team, Six Rivers...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

Creator:: Smith, Danielle D.
Abstract:: The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...

Tillage of compacted soil in a thinned Douglas-fir stand in western Oregon : soil density and residual tree growth seven years after treatment

Creator:: Martinez Ben, Jesus
Abstract:: A set of 119 study trees was identified in a 65 year-old Douglas-fir stand after a thinning operation conducted seven years ago using pre-planned skid trails and groundbased machinery. Some of the trails were tilled using a winged subsoiler after this operation in order to alleviate the effect of compaction...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Short-term relationship of timber management and Pacific giant salamander populations, and the response of larval stream amphibian to predators under differing sediment levels

Creator:: Leuthold, Niels C.
Abstract:: In the Pacific Northwest, multiple studies have found negative effects of timber harvest on stream amphibians, but the results have been highly variable and region-specific. In this collection of studies, I examined the short term effect of timber harvest using a field study, and used lab work to examine a...

Estimating the impacts of a vehicle mileage fee using a discrete continuous choice modeling approach

Creator:: Valluri, Divya
Abstract:: The gasoline tax, the main source of highway revenue is no longer a viable source of funding to maintain the existing highways. Many states in the United States are already using revenues from other sources such as sales tax and income tax to fund new highways. Oregon along with many...

Baseline stream chemistry and soil resources for the Hinkle Creek Research and Demonstration Area Project

Creator:: George, Robert Lance
Abstract:: This research addressed the opportunity to obtain baseline data for both stream chemistry and soil resources for an intensively managed forest watershed, encompassed by the North and South Forks of Hinkle Creek Watershed Research and Demonstration Area Project near Sutherlin, Oregon. A solid representative database for both stream and soil...

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...
