Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Timing of Volcanism in Central Oregon: Dating Tam McArthur Rim Volcano

Creator:: Landoni, Katherine G.
Abstract:: The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...

Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

A Dysfunctional System: Policy Recommendations for the Adult (18-65) Homeless and Severely Mentally Ill Population in Oregon

Creator:: Miller, Donielle F.
Abstract:: Adults with severe and persistent mental illness (SPMI) are overrepresented in the homeless population, and Oregon’s homeless population has expanded in recent years. In the 1950s, the mentally ill were moved out of the state hospitals and into the community. However, due to a lack of support services in the...

Mutagenic Analysis of Victorin Sensitivity in Arabidopsis thaliana and Avena sativa

Creator:: Seshadri, Rishi S.
Abstract:: The fungal pathogen Cochliobolus victoriae, the causal agent of Victoria blight, produces a host-selective pathogenicity factor called victorin. In Arabidopsis thaliana, a dominant gene called "supersense" (SSN) confers constitutive victorin sensitivity at very low concentrations. SSN encodes a nucleotide-binding leucine-rich-repeat (NB-LRR) protein. In the SSN-carrying Heiligkreuztal 2 ecotype (TAIR Germplasm...

Are Any Coastal Internal Tides Predictable?

Creator:: Nash, Jonathan D., Shroyer, Emily L., Kelly, Samuel M., Inall, Mark E., Duda, Timothy F., Levine, Murray D., Jones, Nicole L., and Musgrave, Ruth C.
Abstract:: Surface tides are the heartbeat of the ocean. Because they are controlled by Earth's motion relative to other astronomical objects in our solar system, surface tides act like clockwork and generate highly deterministic ebb and flow familiar to all mariners. In contrast, baroclinic motions at tidal frequencies are much more...

Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Marshall, Kristin N., Shelton, Andrew O., Matkin, Craig, Burke, Brian J., and Ward, Eric J.
Abstract:: Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species of pinnipeds and killer whales (Orcinus...

Can Observation Skills of Citizen Scientists Be Estimated Using Species Accumulation Curves?

Creator:: Kelling, Steve, Johnston, Alison, Hochachka, Wesley M., Iliff, Marshall, Fink, Daniel, Gerbracht, Jeff, Lagoze, Carl, La Sorte, Frank A., Moore, Travis, Wiggins, Andrea, Wong, Weng-Keen, Wood, Chris, and Yu, Jun
Abstract:: Volunteers are increasingly being recruited into citizen science projects to collect observations for scientific studies. An additional goal of these projects is to engage and educate these volunteers. Thus, there are few barriers to participation resulting in volunteer observers with varying ability to complete the project’s tasks. To improve the...
