Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

Detecting medusahead (Taeniatherum caput-medusae (L.) Nevski) using high frequency, sequential, globally positioned digital images

Creator:: Ndzeidze, Stephen Koghan
Abstract:: Invasive plant species are expanding and transforming vegetative communities across Oregon and throughout the United States. Over the past three decades remote sensing, geographic information system (GIS), and Global Positioning System (GPS) technologies have been integrated to detect and map the distribution of noxious rangeland plants. This study developed low-cost...

Concurrent remediation for inadequate preparation for the calculus

Creator:: Hunt, Howard C.
Abstract:: This investigation was designed to determine whether a remediation program concurrent to enrollment in the Calculus could be used to reveal and remedy student deficiencies involving pre-calculus topics, promoting a greater degree of success in the Calculus. The instructional model for the program that was investigated consisted of pretesting the...

The effects of mechanical damage on residual coastal Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) following commercial thinning

Creator:: Kiser, James D.
Abstract:: Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

The Oregon Coastal Subprovince, a new biogeographic subprovince for primary freshwater fishes in Oregon

Creator:: Kettratad, Jes
Abstract:: The Pacific Northwest has a relatively low diversity of primary freshwater fishes with most of the endemism and diversity in the Columbia River and Klamath River. However, the Oregon Coastal Subprovince defined as the coastal rivers from Miami River in the north to Sixes River in the south, has a...

Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...

Sorption by detached organic films and its relation to filiform corrosion

Creator:: Kennedy, George Hunt
Abstract:: The rate of interaction of carbon dioxide with eight detached organic films commonly used as coatings for metal surfaces was examined. The films studied were lacquers of several different formulations including oleoresinous, phenolic, vinyl, alkyd, epoxy, and hydrocarbon types. The sorption was measured on a McBain type gravimetric adsorption balance...
