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...

Dry coniferous forests in the Western Oregon Cascades

Creator:

Means, Joseph E.

Abstract:

Pseudotsuga menziesii dominates the forests of the Pacific Northwest. But though it is dominat, Tsuaa heteroohylla or Abies amabilis is usually climax. Many researchers have studied Pseudotsuga on the widespread mesic sites where it is seral, but few have examined the relatively rare ecosystems in which Pseudotsuga or its associate...

The structure and dynamics of old-growth Sitka spruce (Picea sitchensis) forest of the Oregon Coast Range

Creator:

Quaye, Eric Charles

Abstract:

The objectives of this study are to: 1) study the variations among stands of old-growth Sitka spruce forest located within a relatively restricted geographical area, 2) determine the relationship between species distribution, vegetational pattern, and such site factors as slope and aspect, and 3) ascertain the abruptness of phytosociological change...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:

Stewart, Glenn H.

Abstract:

The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Responses of forest understory plants to burial by volcanic tephra from Mount St. Helens, Washington

Creator:

Antos, Joseph A.

Abstract:

The effects of burial by tephra (volcanic aerial ejecta) on forest understory plants were examined northeast of Mount St. Helens, Washington, in the area where the 18 May 1980 eruption deposited tephra but did not destroy canopy trees. At six sites along a tephra depth gradient from 2-15 cm, understory...

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...

Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:

Schisler, David Albert

Abstract:

Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...
