Scratching the Surface of the Potato Geocaulosphere: Characterizing the Microbiome of Seed Tuber Tare Soil and its Impact on the Rhizosphere Microbiome

Creator:: Delventhal, Kayla D.
Abstract:: For tuberizing crops like potato (Solanum tuberosum), the geocaulosphere, or the zone of soil in contact with and influenced by the tuber, is a distinct sphere of microbial life and represents an important interface between the potato crop and the soil environment. Upon potato harvest, specific geocaulosphere soil called tare...

Diversity and Impact of Soft Rot Pathogens of Potato in the Columbia Basin

Creator:: Brazil, Jessie A.
Abstract:: Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...

Two projectiles connected by a flexible tether dropped in the atmosphere

Creator:: Frost, Geoffrey W.
Abstract:: This study investigates the atmospheric flight dynamics of a munition system and the effect of a tether reel resistance mechanism for limiting the impact that the unreeling process has on the munition system. The munition system consisting of two projectiles connected by a tether line is released from an aircraft...

A biogeographical analysis of some relationships between man, land, and wildlife in Belize (British Honduras)

Creator:: Frost, Marvin D.
Abstract:: This thesis research consists of an investigation of the human influences on wildlife in Belize. The study was accomplished by the collection and analysis of data with respect to land use, habitat characteristics, and wildlife status in Belize. Requirements and status of many species are tabulated in order to give...

Exploring the New Visual Environment as a Strategy to Facilitate Successful Student Adjustment to Culture Shock Associated with Study Abroad

Creator:: DeVito, Laura
Abstract:: This thesis seeks to explore how visual cues in the new environment affect Chinese international students studying abroad in the United States. Through open-ended interviews, Photovoice, and focus groups, Chinese international students shared their perspectives on their orientation, residence, campus places, color association, and on-campus place preferences. During the study,...

Lichen Functional Trait Variation Along an East-West Climatic Gradient in Oregon and Among Habitats in Katmai National Park, Alaska

Creator:: Spickerman, Kaleigh
Abstract:: Functional traits of vascular plants have been an important component of ecological studies for a number of years; however, in more recent times vascular plant ecologists have begun to formalize a set of key traits and universal system of trait measurement. Many recent studies hypothesize global generality of trait patterns,...

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...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

Aspects of the foraging ecology of humpback whales (Megaptera novaeangliae) in Frederick Sound and Stephens Passage, Southeast Alaska

Creator:: Szabo, Andrew R.
Abstract:: The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...

Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

Creator:: Lintz, Heather E.
Abstract:: Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity,...
