Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

Civil engineering students' and practicing civil engineers' understanding of engineering concepts

Creator:: Urlacher, Mark A.
Abstract:: The purpose of this thesis is to explore civil engineering students’ and professional civil engineers' understanding of concepts within statics and fluid mechanics. The studies described herein begin to examine theories of situated cognition utilizing concept inventories, which are sets of multiple-choice questions where the incorrect answers are based on...

Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:: Marks, Jade A.
Abstract:: Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....

Short-tailed weasel space use in managed forests of western Oregon

Creator:: Linnell, Mark A.
Abstract:: Although short-tailed weasels (Mustela erminea) are important predators of small mammals, little is known about their space use, habitat selection, or vulnerability to predation in North America. To evaluate the effects of forest management and social structure on home range size and habitat selection of short-tailed weasels, I conducted a...

Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

Creator:: Albins, Mark A.
Abstract:: Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

The impact of shared ownership on virtual team effectiveness

Creator:: Bonnono, Mark A.
Abstract:: This research studied the role of shared ownership on virtual team effectiveness, using student teams enrolled in engineering management coursework at Oregon State University and Virginia Polytechnic Institute. After a thorough review of the literature, the concept of shared ownership was developed. This concept was operationalized as the extent to...

Movements, habitat associations, and survival of Columbian white-tailed deer in western Oregon

Creator:: Ricca, Mark A.
Abstract:: Columbian white-tailed deer (Odocoileus virginianus leucurus, CWTD) are a geographically isolated and federally endangered sub-species for which there is a paucity of recent ecological information. I described and examined sources of variation in spatial use patterns (i.e. home range, areas of concentrated use, and movements), habitat associations, and survival for...

Survey Recruitment Bias and Estimates of College Student Food Insecurity

Creator:: Venable, Victoria, Edwards, Mark, and Jackson, Jennifer A
Abstract:: Having valid measures of college student FI is essential for justifying basic-needs services for students. But college student food insecurity (FI) rates vary significantly across institutions, perhaps partially due to differences in non-response bias resulting from participant recruitment strategies. We tested for effects of recruitment method on measured levels of...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...

Development of an economical, autonomous pHstat system for culturing phytoplankton under steady state or dynamic conditions

Creator:: Golda, Rachel L., Golda, Mark D., Hayes, Jacqueline A., Peterson, Tawnya D., and Needoba, Joseph A.
Abstract:: Laboratory investigations of physiological processes in phytoplankton require precise control of experimental conditions. Chemostats customized to control and maintain stable pH levels (pHstats) are ideally suited for investigations of the effects of pH on phytoplankton physiology, for example in context of ocean acidification. Here we designed and constructed a simple,...
