Using DNA Metabarcoding to Study Interactions Between Native Bees and Plants: Technical Developments and Applications

Creator:: Arstingstall, Katherine A.
Abstract:: Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...

Climate Variability and Plant-Pollinator Networks in the Cascade Range, Oregon

Creator:: Vickers, Melinda
Abstract:: Worldwide, networks of plants and pollinators are faced with the threat of climate change. The extent of this threat and the degree of adaptability is not yet understood. In Oregon, climate change is predicted to bring hotter and drier summers which may have consequences for pollinators and the resources they...

Recovering Lost Ground : Effects of Soil Burn Intensity on Nutrients and Ectomycorrhiza Communities of Ponderosa Pine Seedlings

Creator:: Cowan, Ariel D.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in ponderosa pine (Pinus ponderosa Dougl. ex Laws) forests of central Oregon. The combustion of fuels containing large downed wood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previous studies...

The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

Creator:: Stamm, Elizabeth A.
Abstract:: Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

Analyzing National Geographic as a Case Study for Identifying and Utilizing Narrative Strategies in Environmental Communication

Creator:: Chang, Kei Lin N.
Abstract:: National Geographic’s June 2018 magazine titled “Planet or Plastic?” drew attention to a growing problem throughout the world: ocean plastic. The eight plastic-related articles in the magazine are an example of science communication as a critical method of not only disseminating information but also raising awareness of the marine debris...

Integrating Solutions at the Intersection of Climate Change and Flavor: Breeding for Sustainable Malting Barley and Beer Sensory Characteristics

Creator:: Windes, Sarah
Abstract:: The following thesis consists of four sections: a general introduction, two manuscripts, a general conclusion, and an overall bibliography. The two manuscripts report on: (1) discussing the prospects of developing a perennial malting barley and potential alternative sustainable crop management practices and (2) further exploring the contributions of barley variety...

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....
Resource Type:: Honors College Thesis

Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits

Creator:: Prive, Kathryn A.
Abstract:: Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....

Differences in Evolutionary History and Ploidy Type Shape the Interactions of Populus tremuloides Michx. with Climate

Creator:: Greer, Burke Thomas
Abstract:: Quaking aspen (Populus tremuloides Michx) is a species with high phenotypic plasticity and a broad distribution that, in the last decade, has experienced climate stress-induced mortality called Sudden Aspen Decline (SAD). In order to help mitigate the effects of SAD in the future, we need a better understanding of aspen’s...

Host-Induced Gene Silencing in Black Cottonwood for Control of Septoria Canker: Efficacy and Non-Target Impacts

Creator:: Gordon, Michael I.
Abstract:: Septoria canker remains the most important disease of poplars in intensively managed forest plantations. Genetic resistance has long been considered the best way to manage for this disease. Transgenic resistance mediated by RNA silencing against pathogens and pests (HIGS: host-induced gene silencing) has shown promise in other pathosystems but has...
