Creator:: Pilz, David P.
Abstract:: Field and greenhouse bioassays were used to compare the mycorrhizal associations of Douglas-fir seedlings from undisturbed forests, and nonburned and burned portions of clearcuts on three Sites in the west-central Cascades of Oregon. Field soil transfers and greenhouse soil pasteurization and reinoculation were used to investigate soil biology and inoculum...

Creator:: Borchers, Susan L.
Abstract:: A greenhouse bioassay was used to compare the effects of soils collected at different distances from hardwood species on the growth, mycorrhiza formation, and foliar nutrient concentrations of Douglas-fir seedlings. Soil nutrient concentrations and bulk densities were also determined. Soils were collected from two southwestern Oregon sites that had been...

Abstract:: Miombo woodland and dambo grassland soils were selected to study the effect of soil transfer on early growth of B. petersiana, C. spectabilis, and C. calothyrsus on degraded sites in northern Zambia. The experiment was conducted on previously slash and burned, cultivated, and abandoned sites. Both sterile and unsterile miombo...

Creator:: Fischer, Christine R.
Abstract:: Mycorrhizae are important for plant growth, particularly in nutritionally poor soils. Vesicular-arbuscular mycorrhizae (VAM) are the primary form of mycorrhizae found in tropical plants, and their persistence in the soil as colonizing fungal propagules following deforestation cannot be directly measured. Utilizing the "most probable number" (MPN) method for estimating infective...

Creator:: Goldberg, Susan B.
Abstract:: A grassland restoration project was conducted in Canyonlands National Park on an area recently disturbed due to construction. Two native grasses (Oryzopsis hymenoides and Stipa comata) were seeded with 18 different soil treatments. Stipa density and relative mycorrhizal colonization were measured. None of the soil treatments resulted in significantly greater...
