Histological comparisons of needle tissues of four species of white pine infected by Cronartium ribicola

Creator:: Sweeney, Katarina
Abstract:: Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...

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...

Stratigraphy and depositional environments of the Upper Devonian Fenstermaker Limestone, Eureka County, Nevada

Creator:: Waldman, Jeff L.
Abstract:: The Upper Devonian Fenstermaker Limestone is a thickening-upward sequence of interbedded sandy intrapelsparite and subordinate calcareous siltstone and mudstone which averages 190 ft (58 m) thick in the northern Antelope Range. The Fenstermaker Limestone is revised and restricted herein to include only those rocks above a basinal shale sequence of...

Evaluating the EWEB Model: Institutional Structure as a Determinant in the Success of a Voluntary Landowner Incentive Program

Creator:: Fishler, Hillary
Abstract:: Eugene Water and Electric Board (EWEB) located in Eugene, Lane County, Oregon, is developing a voluntary landowner incentive program that will provide monetary incentives to non-industrial private forest (NIPF) owners in the McKenzie River Watershed, EWEB’s drinking water source for the metropolitan area of Eugene, to promote good stewardship of...

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...

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,...

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...

Characterizing the Plant-Associated Symbionts, Rhodococcus and Agrobacterium

Creator:: Fuller, Skylar L.
Abstract:: Symbioses are a spectrum of interactions between organisms living in closeassociation. These intimate interactions range from mutualism, in which bothorganisms benefit, to parasitism, where one organism benefits at the expense ofthe other. Horizontal gene transfer is the acquisition of genes independent ofvertical transmission and demonstrably promotes the transition of bacteria...

Effects of the Recreational Fee Demonstration Program on backcountry users in Grand Canyon and Everglades National Parks

Creator:: Leahy, Jessica E.
Abstract:: Since the Recreational Fee Demonstration Program was approved in 1996, allowing public land management agencies to collect and retain recreation user fees, several research studies have gathered opinions and attitudes from different groups of recreation users. One particular group, backcountry users of National Parks, had yet to be included. This...

Watershed management in the Johnson Creek Basin

Creator:: Gerhardt, Nikolaus
Abstract:: The Johnson Creek Basin, Oregon is an example of the physical and jurisdictional problems often associated with watershed urbanization. Implementation of solutions to problems of water quality and quantity in the basin have been hindered by political and social constraints. Reasons for the failure of previous management proposals are analyzed...
