An assessment of plant community structure, herbivory, soils, and state-and-transition theory on a winterfat (Krascheninnikovia lanata [Pursh] A.D.J. Meeuse & Smit) ecological site

Creator:: Matney, Casey A.
Abstract:: State-and-transition models (STMs) have been successfully used to describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...

Role of propagule pressure and priority effects on plant establishment during restoration of invaded shrub-steppe

Creator:: Schantz, Merilynn C.
Abstract:: Biological plant invasions are diminishing the ecological integrity and function of ecosystems worldwide. A primary example of this is in the Great Basin of the United States, where invasive annual grasses, like cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae L. Nevski), are dominating many sagebrush-steppe ecosystems. In these invaded...

Cryptogam communities in forest and steppe ecosystems of Oregon, USA

Creator:: Root, Heather T.
Abstract:: I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...

Developing an analysis framework to compare commuter rail service and bus service in the Mid-Willamette Valley in Oregon

Creator:: Roholt, Ian M.
Abstract:: This thesis develops a framework for analyzing the application of commuter rail and bus services between several small urban centers to enhance overall connectivity. The study includes analyzing specific performance criteria for commuter rail service and express bus service based on data from existing systems around the U.S. The study...

A stratigraphic approach to characterize the deposition and storage of organic matter in reservoir sediments

Creator:: Stratton Garvin, Laurel E.
Abstract:: The relationship between carbon burial and sedimentation in reservoirs is unknown, exposing gaps in our fundamental understanding of the transport, processing, and deposition of sediment and organic matter in fluvial and lacustrine systems and contributing to uncertainty in our understanding of the net impact of dams to the global carbon...

Using Resilience and Resistance Concepts to Manage Threats to Sagebrush Ecosystems, Gunnison Sage-Grouse, and Greater Sage-Grouse in Their Eastern Range: A Strategic Multi-Scale Approach

Creator:: Chambers, J. C.
Abstract:: This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Genomic Investigations of Diversity within the Milkweed Genus Asclepias, at Multiple Scales

Creator:: Weitemier, Kevin A.
Abstract:: At a time when the biodiversity on Earth is being rapidly lost, new technologies and methods in genomic analysis are fortunately allowing scientists to catalog and explore the diversity that remains more efficiently and precisely. The studies in this dissertation investigate genomic diversity within the milkweed genus, Asclepias, at multiple...
