Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...

Taxonomy of desert truffles : the genera Phaeangium and Tirmania

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi are important in food production of arid lands. The desert truffles not only form a symbiotic association with range plants but also form fruiting bodies which are both prized as food and nutritious. The taxonomy and ecology of two genera of desert truffles are treated in this thesis....

Patterns of ectomycorrhizal host-fungus specificity in the Pacific Northwest

Creator:: Molina, R.
Abstract:: Results from approximately 400 fungus-host pure culture inoculations indicate that specificity of ectomycorrhizal associations is a complex phenomenon and cannot be based solely on field observations of sporocarp-host associations. Of the numerous sporocarp-host specific fungi tested, most formed ectomycorrhizae with one or more unexpected, non-associated hosts. These results conclusively demonstrate...

Nursery, cold storage, and field studies on western conifers inoculated with spores of Pisolithus tinctorius

Creator:: Alvarez, Isabel Fernandez
Abstract:: Inoculations of white fir, Shasta red fir, Douglas fir and ponderosa pine with Pisolithus tinctorius spores when outplanted failed to produce P. tinctorius mycorrhizae at the end of the first growing season. In the third year a few P. tinctorius mycorrhizae were formed on white fir. Inoculations reduced seedling survival...

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...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Decay caused by infection of Fomes cajanderi Karst : in top-broken, young-growth Douglas-fir trees

Creator:: Cahill, James M.
Abstract:: A glaze storm of exceptional severity was seen in the Corvallis area, January, 1942. The weight of ice that accumulated in the crowns of young-growth Douglas-fir trees caused widespread top breakage in many stands lying in the broad path of this storm. Early research on this phenomenon showed the majority...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...
