  • Site tenacity, mate retention and sexual dimorphism in Black Terns

    Creator:
    Stern, Mark A.
    Abstract:
    Between 1982-1984 I studied site tenacity and mate retention in Black Terns at Sycan Marsh, Lake County, Oregon. I banded 778 adult Black Terns and used this marked population to test the hypotheses that site tenacity and mate retention would be less for Black Terns which nest in variable marsh...

  • 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...

  • Dietary factors influencing enteric disorders of rabbits

    Creator:
    Grobner, Mark A.
    Abstract:
    An extensive literature review into the causes and controls of diarrhea was followed by three weanling rabbit performance trials to examine the influence of dietary modifications on diarrhea in the rabbit. In the first set of experiments, the ion exchangers clinoptilolite (0, 1.5 and 3.0%) and sodium bentonite (0 and...

  • Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

    Creator:
    Morris, Mark A.
    Abstract:
    Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...

  • A direct-conversion offset-cancellation mixer in 2.4 GHz CMOS

    Creator:
    Lehne, Mark A.
    Abstract:
    We present a new circuit design for adaptive offset cancellation in a fully differential 2.4 GHz CMOS direct conversion mixer. Our circuit structure is a modification of a Gilbert cell mixer in which offsets are cancelled by injecting cancellation currents into the legs of the mixer by dynamically varying the...

  • Controlling biodeterioration of western wood species with over- the-counter wood preservatives

    Creator:
    Newbill, Mark A.
    Abstract:
    Over-the-counter (OTC) wood preservatives can provide wood with both a moisture barrier and fungicidal protection against biodeterioration, yet there is little comparative data on the performance of these preservatives. In this study, the potential of various low-toxicity, OTC preservatives was evaluated on five western wood species, western red cedar (Thuja...

    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...
