Supplemental Description of Myxobolus squamalis (Myxozoa) & Epidemiology of M. squamalis at Two Oregon Hatcheries

Creator:: Polley, Tamsen M.
Abstract:: Myxobolus squamalis is a Myxozoan parasite of salmonids, which contributes to lowered fitness of hatchery and wild fish in the Pacific Northwest of North America. The only GenBank DNA sequence of M. squamalis is from Oncorhynchus tschawytscha (Chinook), but is not linked to a published morphological description. There is a...

Analysis of Organochlorine Pesticides (OCPs) in Gray Whale Scat as an Alternative Method of Toxicant Quantification in Cetaceans

Creator:: Kutnerian, Amy M.
Abstract:: A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...

The Impact of COVID-19 on the Operation and Perceived Effectiveness of Housing Insecurity Programs

Creator:: Morreale, Julianne G.
Abstract:: This study sought to understand the unique challenges that housing insecurity programs faced during the COVID-19 pandemic. An anonymous Qualtrics survey, containing closed- and open-ended questions, was sent to housing insecurity programs in Benton County, Oregon. Questions focused on how the COVID-19 pandemic affected services and how programs adjusted to...

Exploring the Effects of Voice Humanness and Canned Laughter on Robot Comedy Performance

Creator:: Bui, Timothy G.
Abstract:: With robots becoming increasingly commonplace in today’s society, we need to find ways to help robots to become better accepted. One common method used to gain acceptance and build rapport is through the use of humor. Currently, research in robot comedy exists, albeit it is fairly limited. Our goal with...

Empathy-Induced Distress: A Psychophysiological Approach

Creator:: Karabinas, Isabella M.
Abstract:: Empathy is considered a significant motivator of prosocial behavior. Increasing evidence suggests that feelings of personal distress associated with empathy may be stronger or weaker according to the form of perspective taking that an empathizer utilizes. The aim of the present study was to further quantify the stress consequences and...

Abiotic and biotic predictors of coastal giant salamander (Dicamptodon tenebrosus) in headwaters of the Oregon Coast Range

Creator:: Neal, Nathaniel G.
Abstract:: From British Columbia to northern California, coastal giant salamanders (Dicamptodon tenebrosus) are a dominant vertebrate predator in headwater streams. Though widespread, salamander health and abundance levels differ greatly between locations, provoking the question as to what factors may influence this variation and whether habitat features or biotic variables play a...

Importance of TLR2 and TLR4 signaling against M. abscessus infection of macrophages and use of mycobacteriophage genomics toward understanding some of the aspects of phage therapy

Creator:: Kapoor, Hannah A.
Abstract:: Mycobacterium abscessus (MAB) is an opportunistic pathogen responsible for infections in immunocompromised or immunosuppressed patients. Even with long-term treatment with multiple antibiotics, MAB pulmonary infections have high rates of treatment failure. Within the host, MAB is phagocytosed by key innate immune cells macrophages. The TLR2 and TLR4 are two critical...

Inhibition of α-Amylase and α-Glucosidase by Bioflavonoids

Creator:: Griffith, Anneke M. (Tucker)
Abstract:: Various flavonoid-rich plant extracts have shown efficacy in the treatment of diabetes. Although it is often assumed that dietary flavonoids exert biological antioxidant effects, it is possible that the observed effects work in carbohydrate metabolism. In this study we evaluated the effect of catechins and catechin containing extracts on α-amylase...

The Secret Life of Estuaries: Phytoplankton-determined Seasonality of Particulate Organic Carbon in Cathlamet Bay and the Columbia River Estuary

Creator:: Shumway, David O.
Abstract:: This study investigated the composition and character of organic matter on suspended particulate material (SPM) in the Columbia River estuary system to determine the contribution of biological activity in lateral bays to the greater nutrient cycle of the river. Water samples were collected during neap and spring tidal forcing (25...

Survey of rhizosphere associated entomopathogenic fungi on small fruits and Christmas trees in the Willamette Valley, OR

Creator:: Fisher, Joanna J.
Abstract:: The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are commercially available as microbial control agents for the black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), the key root-feeding insect pest in Pacific Northwest small fruits and ornamentals. Understanding habitat selection is critical to improve the efficacy, persistence and cost of...
