Geochemistry of Plutonic Rocks of the Western Cascades, Washington & Oregon : Relationship to Crustal Segmentation and Ore Genesis

Creator:: Utevsky, Elinor S.
Abstract:: The volcanic (~45-10 Ma) and plutonic rocks (~37-12 Ma) comprising the Western Cascades extend from northernmost California to southern British Columbia and are ancestral to modern arc magmatism. The ancestral arc hosts a series of small plutons that are locally associated with porphyry (Cu-Mo) and epithermal (Au) ore deposits. Three...

The Role of Intraspecific Functional Trait Variation in the Differential Decline of Meadow Species Following Conifer Encroachment

Creator:: Celis, Jessica
Abstract:: In the Oregon Cascade Range, conifer encroachment has reduced the extent of mountain meadows by as much as 50% since the mid-1940s. Although encroachment results in a general decline of meadow species abundance and diversity, species differ in their sensitivities to encroachment: some show rapid declines whereas others persist in...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Trickle-down ecohydrology : complexity of rainfall interception and net precipitation under forest canopies

Creator:: Allen, Scott T.
Abstract:: Rainfall interception is a primary control over the moisture input to a forested ecosystem through the partitioning of precipitation into throughfall, stemflow, and an evaporated component (i.e. the interception loss). Rainfall interception is a spatially and temporally varying process at multiple scales, but heterogeneity in interception processes are poorly understood...

Influence of spatial and temporal factors on plants, pollinators and plant-pollinator interactions in montane meadows of the western Cascades Range

Creator:: Pfeiffer, Vera W.
Abstract:: Montane meadows comprise less than 5% of the landscape of the western Cascades of Oregon, but they provide habitat for diverse species of plants and pollinators. Little is known about plant-pollinator network structure at these sites. This study quantified plant-pollinator interactions over the summer of 2011, based on six observations...

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...

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...

Comparing anuran performance and movement

Creator:: Bredeweg, Evan M.
Abstract:: Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...

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...

Climate change impacts on mountain snowpack presented in a knowledge to action framework

Creator:: Sproles, Eric A.
Abstract:: Throughout many of the world’s mountain ranges snowpack accumulates during the winter and into the spring, providing a natural reservoir for water. As this reservoir melts, it fills streams and recharges groundwater for over 1 billion people globally. Despite its importance to water resources, our understanding of the storage capacity...
