Migratory behavior and passage of redband trout (Oncorhynchus mykiss) in the Donner und Blitzen River, Oregon

Creator:: Anderson, Matthew C.
Abstract:: Salmonids in arid high-elevation streams find themselves at the fringe of their tolerance range. Under the conditions they endure in such environments, long-distance migratory movements among widely dispersed habitats may be an important mechanism for some fish to persist, and even thrive. The Donner und Blitzen (Blitzen) River redband trout...

Assessing Mechanisms of Douglas-fir Growth Response to Operational Nitrogen Fertilization in Western Oregon

Creator:: Putney, Jacob D.
Abstract:: Nitrogen (N) fertilizer is a commonly applied silvicultural treatment in intensively managed Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] plantations. When attempting to maximize average growth responses through fertilization, landowners experience difficulty prioritizing stands for treatment based on the likely magnitude of response and return on the operational investment. Field trials were...

Drivers of Soil Fungal Communities Across Three Tropical Rainforests in Panama

Creator:: Schappe, Tyler
Abstract:: Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...

Emerging infectious disease in lentic environments : the ecology and biogeography of the amphibian chytrid fungus Batrachochytrium dendrobatidis, with perspectives on water quality, limnology, and chemical contaminants

Creator:: Chestnut, Tara
Abstract:: Biodiversity losses in terrestrial, freshwater, and marine systems are accelerating at a global scale and the most threatened vertebrate taxa are those associated with freshwater habitats. The causes of biodiversity losses are often complex and include synergistic effects of natural and human-induced stressors, such as habitat loss and fragmentation, urbanization,...

Development of a problem-based learning classification rubric for community college instruction

Creator:: Knelly, Leah J.
Abstract:: Problem-based learning (PBL) is one type of inquiry-based learning. Many community college instructors use inquiry-based learning as an instructional strategy. There is much literature on the use of problem-based learning in undergraduate, graduate and medical school education, with a multitude of examples of specific techniques and problems to be addressed,...

Local and downstream effects of contemporary forest harvesting on streamflow and sediment yield

Creator:: Zégre, Nicolas P.
Abstract:: This dissertation is a collection of three manuscripts that serve to fill the knowledge gaps and advance methods of detecting the effects of contemporary forest harvesting in experimental catchment studies. While there is a preponderance of studies evaluating the environmental effects of forest harvesting in the western United States, few...

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...

Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

Converting forest biomass to energy in Oregon : stakeholder perspectives on a growing movement

Creator:: Stidham, Melanie
Abstract:: Within Oregon there is considerable interest in the possibility of converting woody biomass to energy. This interest stems from three converging factors: the desire to reduce the threat of uncharacteristic wildfire by removing excess material from the forests, the possibility to stimulate rural economies that are dependent on forest products,...

Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

Creator:: Valente, Jonathon J.
Abstract:: Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...
