Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:

Smith, Jane E. (Jane Elizabeth)

Abstract:

Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

Port-Orford-cedar and Phytophthora lateralis : grafting and heritability of resistance in the host, and variation in the pathogen

Creator:

McWilliams, Michael G.

Abstract:

Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to a small area of Oregon and California. A root disease caused by Phytophthora lateralis causes widespread mortality of Port-Orford-cedar. This dissertation examines three important elements of the Port-Orford-cedar P. lateralis pathosystem related to breeding for disease resistance: use of resistant rootstocks...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:

Lewis, Katherine JoAnn

Abstract:

The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

Effects of single and multiple stressors on communities of wheat and wild oats

Creator:

Pfleeger, Thomas G.

Abstract:

Most plant toxicology tests developed in support of environmental laws use a single stress applied to an individual plant. While tests using individual species or stresses require fewer resources and are easier to interpret, they are under increasing criticism for being unrealistic and missing important ecological interactions. The objective of...

Epiphytic macrolichens in relation to forest management and topography in a western Oregon watershed

Creator:

Berryman, Shanti D.

Abstract:

This dissertation describes patterns in epiphytic macrolichen community composition, diversity, and biomass across various stand types in the Blue River watershed of western Oregon. It first examines the relative importance of ecological factors such as stand age, remnant tree retention, and topography to lichen communities in the landscape. It then...

Biology and control of Fusarium spp. on Douglas-fir (Pseudotsuga menziesii)

Creator:

Hoefnagels, Mariëlle Henriette, 1965-

Abstract:

Fusarium spp. are among the most important pathogens of Douglas-fir (Pseudotsuga menziesii) seedlings in bareroot nurseries. Currently the most effective disease control method is soil fumigation with methyl bromide. As methyl bromide is phased out, however, other disease management strategies may become more important. We explored two alternative approaches to...

Establishment of Poria carbonica in wood and colonization by basidiomycetes of Douglas-fir utility poles during air seasoning

Creator:

Przybylowicz, Paul

Abstract:

Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...

Population viability analysis of endangered plant species : an evaluation of stochastic methods and an application to a rare prairie plant

Creator:

Kaye, Thomas N.

Abstract:

Transition matrix models are one of the most widely used tools for assessing population viability. The technique allows inclusion of environmental variability, thereby permitting estimation of probabilistic events, such as extinction. However, few studies use the technique to compare the effects of management treatments on population viability, and fewer still...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:

Meinke, Robert James

Abstract:

The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...
