Role of Extreme Events on Sedimentation in Loon Lake, Oregon Coast Range, USA

Creator:: Richardson, Kristin Noel Duckworth
Abstract:: Sediment cores were retrieved from a landslide-dammed lake, recording events back to the 5th century AD in a forested, mountainous catchment. These cores provide an opportunity to compare the impacts of known recent perturbations, including floods and timber harvesting with those of the early period of the core, flood, fire,...

Quantifying Impacts of Forest Fire on Soil Carbon and Erosion in a Young, Intensively Managed Tree Farm in the Western Oregon Cascades

Creator:: McCool, Katherine D.
Abstract:: Forest soils of the Pacific Northwest contain immense amounts of carbon (C). Increasing acreage burned by severe wildfire in the western Oregon Cascades threatens belowground carbon stocks and future site viability. This study investigates forest soil carbon changes after the 2020 Holiday Farm wildfire in a young, intensively managed Douglas-fir...

Relationship of Soil Type and Burn Severity to Post-Fire Vegetation Response

Creator:: Maclennan, Audrey
Abstract:: Public lands in the Pacific Northwest are managed for multiple uses including timber production, recreation and aesthetic value, maintaining wildlife habitat, conserving native species, and carbon storage. Wildfires impact large areas encompassing broad environmental conditions. Interactions among underlying environmental gradients and alteration of overstory competition by fire of varying severities...

Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction Manipulations in Oregon Cascade Forests

Creator:: Gallo, Adrian Carlos
Abstract:: Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...

Effects of season and interval of prescribed burns on pyrogenic carbon cycling in ponderosa pine stands in Malheur National Forest

Creator:: Matosziuk, Lauren
Abstract:: In ponderosa pine (Pinus ponderosa) forests of the western United States, prescribed fires are used to reduce fuel loads and restore historical fire regimes. The season in which prescribed burns are performed and the interval between burns can have complex consequences for the ecosystem, including soil carbon cycling through the...

Exploring Soil-Landscape Relationships on the Pacific Slope of Monteverde, Costa Rica

Creator:: Hesson, Kevin M.
Abstract:: Landscape positions have been used to determine soil properties. My soil study in Monteverde on the Pacific slope of Costa Rica was designed to examine soil-landscape relationships for sites with various land use histories and management. Soil pits were dug at Nacimiento y Vida, Crandell, Curi-cancha, La Calandria, and Finca...

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

The use of lysozyme in winemaking : the interaction of lysozyme with wine and efficacy in preventing malolactic fermentation in Oregon Pinot noir and Chardonnay

Creator:: Green, Jeffery L.
Abstract:: Hen egg white lysozyme is a hydrolytic enzyme effective at preventing the growth of Gram positive bacteria by degrading the bacterial cell wall to a point of cell lysis. Investigating lysozyme as a processing tool in wine to control the growth of lactic acid bacteria and malolactic fermentation has significant...

A study of hyporheic characteristics along a longitudinal profile of Lookout Creek, Oregon

Creator:: Ninnemann, Jeffery J.
Abstract:: The primary goal of this research project is to quantitatively measure the temporal scales of hyporheic exchange along a stream network. Our goal is to examine how hyporheic exchange varies with increasing stream size. Many previous studies focus on single stream reaches or on several reaches of similar sized streams,...

A programmable BiCMOS transconductance-capacitor filter for high frequencies

Creator:: Beck, Jeffery S.
Abstract:: With advancements in CMOS technology, high speed analog circuits that were traditionally implemented with discrete circuit components can now be made monolithically. Antialiasing filters for video signals as well as signal conditioning filters in high speed communication channels are examples of applications where high frequency integrated circuits are now feasible....
