Hydrogeography of Cloudburst Flooding in the Himalaya

Creator:: Michelsen, Sonja
Abstract:: Even though cloudburst events in high mountain areas can be highly destructive and result in significant losses of life, little is known definitively about these flood events. An exact understanding of the driving processes, typical precipitation rates, and impacts of cloudburst events remain uncertain. This study seeks to advance knowledge...

Ecology and distribution of red crossbill call types in western Oregon

Creator:: Centanni, Caleb
Abstract:: Red Crossbills (Fringillidae: Loxia curvirostra), irruptive finches which feed on conifer seeds, have long presented an evolutionary conundrum. Variable morphology and vocalizations in the species can be classified into several flight call types, which may be discrete lineages. The key conifer hypothesis suggests that each type diverged by specializing on...

The ecology of disease and anthropogenic stressors in amphibians

Creator:: French, Kellie M.
Abstract:: We proposed to test the hypothesis that ecologically relevant concentrations of pesticide mixtures will increase susceptibility of metamorphic amphibians to a fungal pathogen known as Batrachochytrium dendrobatidis, or Bd. Bd has received considerable attention as one of the causes of declining amphibian populations. We hypothesized that exposure to the contaminants...

Metagenomics Analysis Reveal Host-Microbe Interactions in Cervical Cancer

Creator:: Lam, Khiem C.
Abstract:: Cervical cancer is the fourth most common cancer in women worldwide. Recently it has been shown that microbiota play a role in some types of cancer. Therefore, to understand whether microbes contribute in any way to the development and progress of cervical cancer, we investigated the cervical microbiome via analysis...

Geographic variation in the seed mycobiome of Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii)

Creator:: Bergmann, Gillian E.
Abstract:: Seeds are an essential component of plant life histories, and seed endophytes have the potential to influence germination, seedling establishment and development. That said, seed endophytes are a relatively new area of study, both in the factors that influence which taxa are present and how these microbes alter plant function....

Intertidal Ecology along the Western Coastlines of the Pacific : Upwelling and Bottom-up Effects in Chile and Oregon

Creator:: Murphy, Christina A.
Abstract:: The coastal regions of Chile and Oregon are some of the most productive ecosystems in the world. The intertidal communities of both areas have been well studied, but much remains to be learned about how those communities are structured over large scales. Here, I explore the upwelling regimes and the...

Localization of the CB1 receptor in the brain of Taricha granulosa

Creator:: Aubert, Jolene E.
Abstract:: The psychoactive component of marijuana, A9-tetrahydrocannabinol (THC), is known to have effects in humans that are mediated by the cannabinoid receptor (CB 1). Although a great deal of research has been done to confirm the interaction of exogenous cannabinoids with the CB 1 receptor, little is known about the receptor's...

Response of reef fish assemblages to overgrowth of the hydrocoral Millepora complanata by the crustose alga Ramicrusta sp.

Creator:: Adams, AnnaRose
Abstract:: Natural disturbances and human activities can alter the benthic composition of coral reefs and other marine ecosystems. Reef fishes that associate with particular structures on the sea floor, such as coral heads, may be vulnerable to perturbations of those habitats. The spread of a newly discovered crustose alga (Ramicrusta sp.)...

Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

De novo Discovery of Novel Long Noncoding RNAs in the North American Beaver

Creator:: Kashyap, Amita
Abstract:: Long noncoding RNAs (lncRNAs) are RNA molecules that are at least 200 nucleotides long and do not encode proteins. lncRNAs have roles in gene regulation, chromatin epigenetics, and molecular scaffolding. In light of mounting evidence implicating species-specific noncoding RNAs and gene regulatory mechanisms in species adaptations, it is reasonable to...
