  • Conifer phytotoxicity and vegetation control efficacy of ten selected herbicides

    Creator:
    Coate, Jeremy E.
    Abstract:
    Ten herbicides (atrazine, azafenidin, chlorsulfuron, clopyralid, hexazinone, imazapic, imazapyr, metsulfuron, pendimethalin, and sulfometuron) were evaluated for phytotoxicity in first-year seedlings of eight conifer species (Douglas-fir, grand fir, noble fir, redwood, Sitka spruce, western hemlock, western red cedar, and western white pine). Six of these herbicides (atrazine, clopyralid, hexazinone, imazapyr, metsulfuron,...

  • Factors affecting the dynamics and regulation of coral-reef fish populations

    Creator:
    Webster, Michael Scott
    Abstract:
    Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

  • Gas chromatography/olfactometry and descriptive analysis of cold-pressed lemon oil aroma

    Creator:
    Young, Sheri L.
    Abstract:
    Lemon oil quality is affected by numerous factors including lemon variety, climate, soil type, extraction method, etc.. Therefore, quality largely depends upon the lemons' origin, and aroma profiles of oils obtained throughout the world have potential to vary considerably. This research was conducted to identify differences in the aroma profiles...
