This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...
There was a linear relationship of [alpha]-amylase activity
from 2 to 12 hours incubation in both freeze-dried and fresh
'd'Anjou' pear fruit tissue. Activity was greater, however,
in fresh as compared with freeze-dried tissues. [alpha]-Amylase
activity from both types of samples was not detected until
60 minutes incubation. After 90...
Discrete layers of phytoplankton and zooplankton were observed over the Oregon continental shelf in summer and fall of 2001 and summer 2002 using optical and acoustical technologies and a pump sampling system. Layers of phytoplankton had steep vertical gradients which were associated with gradients in density and local peaks in...
An experiment was conducted to evaluate the influence of forest fuels reduction on the diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with the whole plots (3 ha) being fuel reduced or no treatment...
Steps and Stikes is an Environmental Arts and Humanities capstone thesis project taking the shape of an art film. The video layers contemporary dance with natural and industrial imagery on a foundation of personal narrative. It engages with contemporary environmental discourse as a choreographed essay, questioning why the environmental movement...
My thesis consists of two articles that address the ways in which rhetoric emerges from coalitions with unequal power dynamics within the environmental movement. The introduction provides context to help situate my articles within the current environmental movement. In my first article, “Constellating a More Intersectional, Coalitional Rhetoric: Lessons from...
The house mouse is an asthma trigger and disease vector, and is difficult to manage. Infestations in schools are managed with exclusion, sanitation, de-cluttering, monitoring, and heavy trapping. Inspections and monitoring focus on droppings, snap traps, and nontoxic baits. Safety precautions should be taken when handling feces and rodent carcasses.
Three approaches for evaluating mode I interlaminar strain energy release rates in graphite/epoxy composites were compared using experimental data from double cantilever beam specimens. Expressions for evaluating strain energy release rates were arrived at based on assumptions regarding specimen geometry and material behavior. The calculations included the direct method of...
A GIS analysis procedure was developed to explore relationships between imagery, yield data, soil information, and other assessments of a field or orchard. A set of conversion utilities, a spreadsheet, and an inexpensive shape file viewer were used to manipulate, plot, and display data. Specific features described include procedures used...
