Abstract:: Red alder (Alnus rubra Bong.) seedlings fertilized with NH4NO3 or inoculated with a pure culture Fran/cia and inoculated with live or dead spores of the mycoirhizal fungus Alpova diplophloeus (Zeller & Dodge) Trappe & Smith were grown in a growth chamber or in a greenhouse for six months Frankia inoculation...

Creator:: Shainsky, Lauri J.
Abstract:: Competitive interactions between Douglas-fir seedlings (Pseudotsuga menziesii), and seedlings of a nitrogen-fixing hardwood associate, red alder (Alnus rubra), were investigated in an addition series experiment. The primary objective of the research was to identify and quantify key processes underlying intra- and interspecific competitive interactions of Douglas-fir and red alder seedlings....

Creator:: St. Clair, John Bradley
Abstract:: Ungerminated seed and recent germinants from 39 open-pollinated Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) families were planted in each of three competitive environments in order to determine the degree to which growth differences among families are influenced by competitive environment, seed weight, and date of emergence. The three competitive...

Creator:: Rose, Jeffrey A.
Abstract:: This research assessed the effect of western juniper (Junlperus occldentalls) removal on understory plant production and cover and ponderosa pine (Pinus ponderosa) growth and plant water status. A complete randomized block design, with four blocks and four treatments was established in the summer of 1984 near Prineville, Oregon. The four...

Creator:: Haeussler, Sybille
Abstract:: The role of disturbance in seed germination and first-year survival of red alder (Alnus rubra) was studied over two growing seasons at four sites representing a climatic gradient within the central Coast Range of Oregon. Disturbance affected red alder seed germination and seedling establishment by altering the temperature and moisture...

Creator:: Goslin, Matthew N.
Abstract:: Trees that survive disturbances can form a prominent legacy which may influence post-disturbance successional pathways. The effects of biological legacies on community dynamics is a critical question in ecology. In the present study, I examined two mapped stands in which old-growth remnant trees, survivors of partial fires, emerge above a...
