Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:

Fleetwood, Shea

Abstract:

Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Undergraduate Thesis
Pelagibacter metabolism of diatom-derived volatile organic compounds imposes an energetic tax on photosynthetic carbon fixation

Creator:

Thompson, Douglas A., Moore, Eric R., Davie-Martin, Cleo L., Giovannani, Stephen J., and Halsey, Kimberly, H.

Abstract:

Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.

VOC Emisions and Categorization in Axenic Growth Conditions by Phaeodactylum tricornutum

Creator:

Thompson, Douglas A.

Abstract:

Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:

Arnold, Madison A.

Abstract:

Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Effects of selenium supplementation during different trimesters of pregnancy on non-specific humoral immunity of pregnant beef cows and persistence of antibodies in their newborn calves

Creator:

Thompson-Hernandez, Ian

Abstract:

Immunosuppression during the periparturient period leads to increased susceptibility to infectious diseases in beef cows. Newborn calves rely on passive transfer of antibodies from their mothers at birth for protection against diseases in the first two months of age. It is unknown if supranutritional Se supplementation of cows during pregnancy...

A Comparative Analysis of Mercury and Lead in Sindoor from the U.S. and Bangladesh

Creator:

Breen, Anna K.

Abstract:

Heavy metals have historically been popular for use in cosmetics manufacturing due to the colorful pigmentation of heavy metal compounds. In the case of sindoor, a cosmetic used by married Hindu women for religious purposes, mercury sulfide, lead tetroxide, and lead chromate are compounds suspected to still be involved in...

Overview of the Comparison of Commercial Pelagic Species Fisheries Management in Malaysia and Oregon, United States

Creator:

Ahmad, Amir

Abstract:

The United Nations Food and Agriculture Organization (FAO) in the State of World Fisheries and Aquaculture 2018, has observed that the trend of the world’s marine fish stocks has been overexploited, depleted, and has exhibited decreasing trend within the fraction of biologically sustainable levels. While these situations are an alarming...

Stomach Analysis of Top Aquatic Predators in a Headwater Stream Network

Creator:

Ain, Najma

Abstract:

Top predators play important roles in regulating communities and ecosystem processes in freshwater ecosystems. In the headwater stream network, it is crucial to understand the interspecific interaction between multiple predators. In Oregon forested ecosystems, Coastal Giant Salamander (Dicamptodon tenebrosus) and cutthroat trout (Oncorhynchus clarkii) are the top predators in many...

Analysis of boscalid resistance of isolates of Botrytis cinerea

Creator:

Villanueva, Brenda

Abstract:

Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...
