Effects of vegetation and disturbance on fungal communities in the western Cascades of Oregon

Creator:: Kageyama, Stacie Ann, 1967-
Abstract:: The use of high throughput molecular methods that allow for the study of bacterial communities in environmental samples is commonplace in microbial ecology. Until recently, fungal community ecology has focused on isolation, collection of sporocarps, or collection of ectomycorrhizal roots. The techniques used to extract and amplify DNA from environmental...

Drivers of arbuscular mycorrhizal fungal community composition in roots : hosts, neighbors, and environment

Creator:: Phillips, Wendy S.
Abstract:: The vast majority of terrestrial plant species live in symbiosis with arbuscular mycorrhizal fungi (AMF). AMF and plants live in complex networks, with roots of individual plants hosting multiple AMF, and single AMF colonizing multiple plants concurrently. Through the exchange of resources, the two partners of this symbiosis can have...

Fungal diversity within decomposing woody conifer roots in Oregon

Creator:: Vandegrift, V. Eleanor
Abstract:: Previous studies have indicated that roots from five tree species (Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Pinus contorta) decompose at different rates across an environmental gradient in Oregon. Measurements of wood chemistry from each tree species as well as moisture and temperature from each location do not...

Effects of disturbance modes on mycorrhizal fungus communities at Crater Lake National Park

Creator:: Trappe, Matt
Abstract:: Crater Lake National Park presents an excellent opportunity for ecological research due to its relatively pristine landscape, the protection of its natural features, its infrastructure, and a Park administration supportive of scientific inquiry and restoration ecology. The research presented here examines the responses of fungi to various forms of perturbation....

Analysis and prediction of patterns in lichen communities over the western Oregon landscape

Creator:: Peterson, Eric B.
Abstract:: The diverse lichen flora of the Pacific Northwest is being impacted by population growth and by forest management practices. Accumulating information about our lichen flora will improve our conservation strategies. This dissertation first collects information to improve our understanding of how lichen communities vary among forests of differing structure, and...

A preliminary classification of forest communities in the central portion of the western Cascades in Oregon

Creator:: Dyrness, C. T., Franklin, Jerry F., Moir, William H., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...

Modeling riparian zone processes : biomass production and grazing

Creator:: Korpela, Edwin J.
Abstract:: Seasonal trends in forage production and environmental parameters for five plant community types within a northeastern Oregon riparian zone were described and modeled using correlation and path analysis. Wet meadows produced the greatest amount of herbage biomass, followed by moist bluegrass meadows, gravel bars, forests and dry bluegrass meadows. Trends...

Community analysis of the Wyoming big sagebrush alliance and functional role of Wyoming big sagebrush

Creator:: Davies, Kirk W.
Abstract:: This study consisted of two research projects in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance, the most extensive of the big sagebrush complex in the Intermountain West. In the first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming big sagebrush...
