Riverscape genetics of Oncorhynchus tshawytscha (Chinook salmon) in Siletz River, OR

Creator:: Davis, Chanté D.
Abstract:: Traditional analysis in population genetics evaluates differences among groups of individuals and, in some cases, considers the effects of distance or potential barriers to gene flow. However, many forces may shape genetic variation of organisms in riverine systems. Similarly complex research linking habitat heterogeneity and configuration to genetic structure has...

Seagrasses as Potential Chemical Refugia for Acidification-Sensitive Bivalves

Creator:: Smith, Stephanie Rae
Abstract:: As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...

Examining the Spatial Distribution of Park Access and Trajectories of Gentrification in Seattle, Washington 1990 - 2010

Creator:: Weems, Candice Michelle
Abstract:: This dissertation examines the spatial distribution of park access by type in relation to trajectories of gentrification in Seattle from 1990 to 2010. The dissertation includes 5 Chapters. The first chapter provides an overview of the literature that motivated this research. The second, third and fourth chapters are research papers...

A Reconstruction of Plant Species Composition at the Devil's Kitchen Site (Southern Oregon Coast) using Plant Opal Phytoliths and Charcoal Macro-remains

Creator:: Bulder, Nicholas H.
Abstract:: Although plant remains, such as opal phytolith and charcoal analyses, have been used since the beginning of the 20th century to reconstruct past environments by ecologists and botanists, only recently have these techniques been considered by archaeologists in understanding the past at the site level. This study employs opal phytolith...

Landscape-Level Approaches to Desert Bighorn Sheep (Ovis canadensis nelsoni) Conservation in a Changing Environment

Creator:: Creech, Tyler G.
Abstract:: Landscape characteristics can strongly influence demographic and genetic processes in wildlife populations. Climate change and human land use are causing many landscapes to change rapidly, and the effects on wildlife populations must be understood to properly manage these threats and design effective conservation strategies. In this dissertation, I explored the...

Glyphosate Resistance and Tolerance in Italian Ryegrass (Lolium perenne spp multiflorum) : Termination Treatments, Cultivar, and Resistance Evaluation

Creator:: MacPherran, Robert Chase
Abstract:: Annual ryegrass, or Italian ryegrass (Lolium perenne spp. multiflorum), has been the most stable, in terms of acres, grass produced for the past 25 years in Oregon. Increased interest in Italian ryegrass as a cover crop has increased demand for quality seed. Ideal Italian ryegrass cover crop cultivars are named...

Comparing Ectomycorrhizal Communities of Understory Giant Chinquapin (Chrysolepis chrysophylla) and Overstory Pinaceae Trees in a Mixed Conifer Forest in Central Oregon

Creator:: Longway, Lucas J.
Abstract:: Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...

Survival Rates and Cause-Specific Mortality of Mule Deer in South-Central Oregon

Creator:: Mulligan, Elizabeth M.
Abstract:: It is critical for wildlife managers to understand the population dynamics of a harvested species, particularly for ungulates, which are a valuable wildlife resource. Due to concerns that mule deer (Odocoileus hemionus) populations in Oregon were declining, more comprehensive data on population vital rates and the factors potentially affecting them...

Population Genetics of American Pika (Ochotona princeps) : Investigating Gene Flow and Genetic Diversity Across Multiple, Complex Landscapes

Creator:: Castillo, Jessica A.
Abstract:: American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...

Essays of Land Use Changes, Open Space, and Water Pollution

Creator:: Hagimoto, Toru
Abstract:: Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate...
