Evaluating Letharia Vulpina Transplants for Bioindication of Nitrogen Deposition

Creator:: Kovasi, Adrienne, McCune, Bruce, and Jovan, Sarah
Abstract:: The epiphytic lichen Letharia vulpina has been commonly sampled in-situ for nitrogen (N) deposition biomonitoring studies but has never before been transplanted for this purpose. In the high-elevation wilderness areas of southern California Letharia vulpina is generally uncommon, making in-situ sampling difficult. In this study, we compared thallus N accumulation...

An Exploration of the Ecological and Geographical Variability of Rhizopus microsporus Clinical and Environmental Isolates

Creator:: Stairs, Brandon S.
Abstract:: Rhizopus microsporus is a globally ubiquitous opportunistic human and plant pathogen that is known to harbor endosymbiotic bacteria. Differences between populations of clinical and environmental R. microsporus isolates have yet to be assessed on a global scale. Whole-genome sequence data were used to explore fungal biology and to assess potential...

Community Ecology and Population Genomics of Rhizopogon in the Madrean Sky Island Archipelago

Creator:: Piña Páez, Carolina G.
Abstract:: Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...

Diseases of Rhododendron and Boxwood: Survey and Virulence of Phytophthora Root Rot and Management of Boxwood Blight with Systemic Fungicides

Creator:: Sacher, Gabriel
Abstract:: Diseases can be a substantial threat to woody plant production, a major industry in Oregon. Boxwood (Buxus spp.) and rhododendron (Rhododendron subgenus Rhododendron and Hymenanthes) represent the top two broadleaf evergreen woody plants by farmgate value in Oregon. Historically, Phytophthora root rot has been considered the most destructive disease of...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

The Ecology and Epidemiology of Xanthomonas hortorum pv. carotae in Central Oregon Carrot Seed Production Systems

Creator:: Baldino, Katelyn D.
Abstract:: Xanthomonas hortorum pv. carotae (Xhc) is an epiphytic, plant pathogenic bacterium that causes the disease bacterial blight of carrot (Daucus carota subsp. sativus). Infection with Xhc can result in blighting of leaves and umbels and reduce quality and yield of carrot seed crops. Carrot production in the United States approaches...

New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

Plant-Pollinator Interactions in a Changing World: Cryptic Specialization, Pollinator Movement, and Landscape Genetics of Pollinator-Dependent Plants

Creator:: Gannon, Dustin G.
Abstract:: Plant-pollinator mutualisms are one of the most prevalent and economically important mutualisms in nature. Like many other ecological systems, plant-pollinator communities are threatened by anthropogenic activity, both directly (e.g., habitat conversion and fragmentation) and indirectly (e.g., climate change). While we are aware of many of the activities that adversely impact...

Lichen Biomonitoring from Valley to Alpine in Central and Southern California

Creator:: Kovasi, Adrienne I.
Abstract:: In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....
