Variation in communities of ammonia-oxidizing and denitrifying bacteria in Fennoscandian boreal forest soils

Creator:: Ghimire, Rama D.
Abstract:: The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...

The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:: Boyle, Stephanie A.
Abstract:: The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...

Tree species-soils relationships in old-growth forests of the Oregon Coast Range

Creator:: Cross, Alison
Abstract:: Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...

Use of MIKE SHE for estimation of evapotranspiration in the Sprague River Basin

Creator:: Shakya, Suva R.
Abstract:: MIKE SHE is a fully distributed, physically-based hydrologic model that can simulate water movement over and under the Earth's surface. Evapotranspiration (ET) is one of the components of this model. MIKE SHE uses a modification of the Kristensen -Jensen (1975) method to calculate actual ET. This method is based on...

Prescribed fire in Eastern Oregon ponderosa pine forests : relationships between soil fertility and ecology

Creator:: Grossmann, Emilie B.
Abstract:: I conducted two separate studies, both related to the impacts of spring and fall prescribed fire on ponderosa pine (Pinus ponderosa Dougl. ex Loud.) forest soils in Eastern Oregon. The studies were either conducted at or linked to four stands of ponderosa pine, in the Malheur National Forest. Each stand...

The Clerk’s Tale : literal monstrosities and allegorical problems

Creator:: Brock, Christopher J.
Abstract:: My thesis, entitled “The Clerk’s Tale: Literal Monstrosities and Allegorical Problems,” argues that Chaucer’s Clerk is engaging both sides of a binary system. The Clerk has situated himself in a precarious position between two major schools of thought in the medieval culture, Franciscan and Dominican; the former promotes the will...

Response of soil microbial communities to physical and chemical disturbances: implications for soil quality and land use sustainability

Creator:: Chaer, Guilherme M.
Abstract:: The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...

Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...
