Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Monitoring pesticide resistance in Psylla pyricola Foerster from western Oregon pear orchards

Creator:: Follett, Peter A.
Abstract:: A modified slide-dip bioassay was used to survey and establish baseline resistance levels in Psylla pyricola Foerster from western Oregon orchards to four pesticides. Orchards selected in the Hood River, Rogue River and Willamette Valleys spanned a wide range of environmental and management conditions. During the study period of 1982-1983,...

Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

Beach foreshore response to long-period waves in the swash-zone

Creator:: Howd, Peter A.
Abstract:: A field experiment designed to test the hypothesis that infragravity and lower frequency waves influence the patterns of erosion and deposition on the beach foreshore has been carried out. The data show coherent fluctuations in the foreshore sediment level which can be related to low frequency wave motions. The fluctuations...

Growth and carbon allocation of red alder seedlings grown over a density gradient

Creator:: Giordano, Peter A.
Abstract:: The amount and quality of competition among individuals in developing plant communities is an important factor determining community structure, composition and development. In perennial plant communities, this competition is reflected by shifts in carbon allocation among plant parts and can result in long-term structural differences between neighboring individuals. This study...

Forested plant associations of the Olympic National Forest

Creator:: Henderson, Jan A., Peter, David H., Lesher, Robin D., and Shaw, David C.
Abstract:: A potential vegetation classification system is presented for the Olympic National Forest. It is based on a sample of 1046 Reconnaissance and 408 Intensive plots. The hierarchical classification includes sixvegetation series and 64 plant associations. Diagnostickeys are presented to aid in the identification of series and associations. Descriptions are presented...
