The athlete and two stories

Creator:: McDonnell, Peter A.
Abstract:: The purpose of this document is to display a portion of the work I have completed over the last two years. The Athlete is the recently written opening to a novel of the same name. I've decided not to excerpt a longer section of the novel because the novel isn't...

Gorsevski, Peter MS.pdf

Creator:: Gorsevski, Peter (Pece) V.
Abstract:: This thesis presents the idea for FORIN (Forest Roads Inventory), a computerized forest roads inventory system. FORIN is a tool to more efficiently inventory and manage information of forest roads. FORIN is intended for use by field personnel, who will use pen-based computers to improve productivity, accuracy of inventories, to...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Hypervitaminosis A : effects on reproduction and interactions with pyrrolizidine alkaloids

Creator:: Moghaddam, Mehran Fallah
Abstract:: In the first experiment the minimum dietary toxic levels of vitamin A were determined in pregnant rabbits over three parities. The treatments consisted of basal diet plus 10,000, 30,000, 60,000, and 90,000 IU/Kg added vitamin A. The basal diet was formulated to be free of vitamin A and beta-carotene; rice...

A macroscale measurement and modeling approach to improve understanding of the hydrology of steep, forested hillslopes

Creator:: Graham, Christopher Brian
Abstract:: The dominant controls on flow generation in steep, forested hillslopes are poorly understood. This dissertation examined the dominant flow processes operating at the hillslope scale, using a combined macroscale measurement and model development and analysis framework. Irrigation experiments at two steep forested hillslopes were conducted to isolate individual hillslope flow...

The role of near-stream zones on flow, chemistry and isotopic composition at the headwater scale

Creator:: Frentress, Jay
Abstract:: Stream discharge is a key water balance component and important factor in global change evaluations. Nevertheless, the mechanisms for streamflow generation are poorly understood. Near- stream surface saturation during precipitation events is one of the most iconic, visible indicators of rapid runoff production in upland humid catchments around the world....

Ecohydrological mediation of water budget partitioning and time scales of subsurface flow in a seasonally semi-arid grassland

Creator:: Pangle, Luke A.
Abstract:: Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Spatial and temporal runoff response to snowmelt, and the influence of geomorphology in a headwater catchment, central eastern Cascades, Washington

Creator:: Alley, David
Abstract:: This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

Climate Warming, Soil Moisture Dynamics, and Water Budget Partitioning: Experimental Results from a Willamette Valley Ecosystem

Creator:: Pangle, Luke, Gregg, Jillian, and McDonnell, Jeffrey
Abstract:: There is reasonable expectation that climate warming will accelerate the hydrologic cycle, resulting in greater evapotranspiration (ET) and reduced groundwater recharge (R) (or stream flow). Though qualitatively intuitive, quantifying these potential shifts in water budget partitioning is a contemporary challenge in hydrology, because the linkage between ET and R is...
