Spatial analysis of Phellinus weirii infection centers in the central Cascades of Oregon : inferring ecological processes from patterns

Creator:: Lattin, Peter D.
Abstract:: This study was conducted to investigate why root disease centers east of the Cascade crest tend to be larger in diameter and more abundant than their counterparts to the west, within subalpine forest stands of central Oregon. The trend in a 290 km² study area appeared opposite of what was...

The influence of light intensity on the phytochemistry of Chrysolepis chrysophylla (Fagaceae) and the relationship to the herbivory of Habrodais grunus herri (Lycaenidae)

Creator:: Bowden, Richard I.
Abstract:: Defensive chemical and nutritive quality of young leaves were measured for 72 individual trees of Chrysolepis [Castanopsis] chrysophylla in conjunction with light intensities of two different stand types and population numbers of Habrodais grunus herri in the Cascade mountains of Oregon. Leaves were collected in the spring and leaf characteristics...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

The relationship of Douglas-fir dwarf mistletoe (Arceuthobium douglasii) to environmental and stand conditions and plant communities in the southern Oregon Cascades

Creator:: Marshall, Katrina
Abstract:: This study examined the relationships between the frequency of occurrence and severity of Douglas-fir dwarf mistletoe (Arceuthobium douglasii Engelmann), environmental and stand conditions, and plant communities in the Southern Oregon Cascade Mountain Province. Data for the study was collected from the same ecology plots that were previously used to define...

Mixed-conifer forests of central Oregon : structure, composition, history of establishment, and growth

Creator:: Merschel, Andrew G.
Abstract:: The structure and composition of mixed-conifer forest (MCF) in central Oregon has been altered by fire exclusion and logging. The resulting increased density, spatial contagion, and loss of fire resistant trees decrease the resiliency of this ecosystem to fire, drought, and insects. The historical and current composition and structure of...
