Epidemiology, Etiology, Genetics and Predictive Surveillance Modeling of the Deer Chewing Louse Damalinia (Cervicola) Species

Creator:: Mortenson, Jack A.
Abstract:: A seasonal hair-loss syndrome of native deer began to occur in the Pacific Northwest United States in the mid-1990s. Clinical manifestations of the disease typically include large numbers of chewing lice on Columbia Black-tailed deer (Odocoileus hemionus columbianus) and Columbia White-tailed deer (Odocoileus virginianus leucurus). Expenditure of energy responding to...

How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

Creator:: Avila, Alexandra M.
Abstract:: Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...

Effects of Aquatic Resource Subsidies on the Ecology of Terrestrial Top Predators

Creator:: Eriksson, Charlotte E.
Abstract:: Energetic resources transferred between distinct habitats or ecosystems, referred to as allochthonous resources, can greatly subsidize consumers in the recipient habitat, and thus influence food web structure and dynamics. Such subsidies may allow the growth of the consumer population to be decoupled from in situ productivity with effects on consumer...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Historical forest succession and disturbance dynamics in Coastal Douglas-fir forests in the southern western Cascades of Oregon

Creator:: Merschel, Andrew G.
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...

In situ Agrobiodiversity Conservation Planning in Centers of Origin: The Role of Culture

Creator:: Guerrero Ochoa, Isabel G.
Abstract:: Managing agricultural diversity ensures a range of public services, such as genetic resource diversity, food security for subsistence-based economies, and landscape resilience in the context of climate change, among others. These agrobiodiversity conservation services are positive externalities from agrobiodiversity conservation. Whereas their value is not captured in market transactions, management...

Inclusion Fusion and Genetic Recombination: Bridging the Gap Between the Chlamydiae

Creator:: Garvin, Lotisha E.
Abstract:: Chlamydia is an obligate intracellular bacterial pathogen that causes a variety of disease in animals and humans worldwide. Veterinary chlamydial pathogens can lead to chronic infections and serious consequences that result in millions of dollars of losses in animals and resources in the agricultural industry in countries that rear ruminants....

Host and Pathogen Genetics in the Sharp Eyespot Disease of Wheat

Creator:: Liu, Jiang
Abstract:: Wheat sharp eyespot (SES), caused by the soil-borne fungus Rhizoctonia cerealis is a common stem disease of wheat globally. The disease caused a severe and extensive epidemic throughout the Willamette Valley of Oregon in 2014 and has remained one of the most important wheat diseases in this region. However, litte...
