Seasonal occurrence and abundance of insect pests and natural enemies in the Columbia Basin

Creator:: Klein, Matthew L.
Abstract:: Potato (Solanum tuberosum L.) is the fourth largest food crop in the world following rice (Oryza sativa L.), wheat (Triticum spp.), and maize (Zea mays subs. mays). Potatoes arrived in the United States in the early 1600s and over the following centuries, the crop was subsequently cultivated across the country...

Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

Creator:: Lightle, Danielle
Abstract:: In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...

Non-spatial and spatial models for multi-host pathogen spread in competing species : applications to barley yellow dwarf virus and rinderpest

Creator:: Manore, Carrie Anna
Abstract:: Modeling and analyzing the combined effects of disease and population dynamics is important in understanding the effects of mechanisms such as pathogen transmission and direct competition between host species on the distribution and abundance of different species in an ecological community. Mathematical analysis of such models in a spatially explicit...

Factors affecting the regrowth of Himalya (sic) blackberry (Rubus armeniacus)

Creator:: Jones, Daniel Karl
Abstract:: Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This...

Nursery container weeds response to modification of substrate pH, substrate particle size and applied nitrogen form

Creator:: Wada, Sugae
Abstract:: Experiments were conducted to determine the influence of cultural management practices on weed growth in nursery containers. Experiments 1 and 2 evaluated the effects of dolomitic lime rate and application method on substrate pH, creeping woodsorrel (Oxalis corniculata L.) establishment in containers, and growth of azalea (Rhododendron ‘Rosebud’) and pieris...

A Microeconomic Analysis of Wildfire Suppression Programs in the Western United States

Creator:: Rossi, David J.
Abstract:: This dissertation studies the microeconomics of forest fire suppression programs. It starts with an inquiry into the causes of increasing shares of public land management budgets devoted to wildland fire suppression in lieu of hazardous fuel reduction or other pre-fire risk mitigation programs. The first two chapters consider competing economic...

Non-Chemical Approaches to Managing Annual Bluegrass (Poa annua L.)

Creator:: Cain, Alyssa B.
Abstract:: Annual bluegrass (Poa annua L.) is a prolific annual grassy weed that can be found worldwide in most landscapes. Known for its ability to produce seedhead at low heights (0.32 cm), thrive in over-maintained areas, and germinate anywhere, annual bluegrass is a highly invasive weed. Due to annual bluegrass’ persistence,...

Frequency, Distribution, Ploidy Diversity and Control Options of Herbicide Resistant Italian Ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) Populations in Western Oregon

Creator:: Bobadilla, Lucas K.
Abstract:: Italian ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) is one of the most troublesome weeds with respect to herbicide resistance selection. Some reasons for this are the numerous documented cases of multiple and cross herbicide resistance and some of the biological characteristics of this species, such as wind cross-pollination...

A Comparative Study on How SVN and Git Affect Software Changes

Creator:: Codoban, Mihai
Abstract:: Distributed Version Control Systems (DVCS) have seen an increase in popularity relative to traditional Centralized Version Control Systems (CVCS). Yet we know little on whether VCS tools meet the needs of software developers when managing software change or whether developers are benefitting from the extra power of DVCS. Without such...

A methodology for real-time scheduling of jobs with splitting on unrelated parallel machines

Creator:: Subur, Fenny
Abstract:: Unrelated parallel machines are machines that perform the same function but have different capacity or capability. Thus, the processing time of each job would be different on machines of different types. The scheduling environment considered is dynamic in both job release time and machine availability. Additionally, each job considered can...
