Spatial analysis of Phellinus weirii infection centers in the central Cascades of Oregon : inferring ecological processes from patterns

Creator:: Lattin, Peter D.
Abstract:: This study was conducted to investigate why root disease centers east of the Cascade crest tend to be larger in diameter and more abundant than their counterparts to the west, within subalpine forest stands of central Oregon. The trend in a 290 km² study area appeared opposite of what was...

The effect of light and nitrogen limitation on western conifers : response to Armillaria ostoyae infection

Creator:: Entry, James A.
Abstract:: Armillaria (Fr. ex. Fr.) is a parasite whose pathogenicity and role in forest ecosystems often depends upon the physiological condition of the tree. Therefore, I tested the frequency and severity of Armillaria ostoyae (Romagn.) Herink infection among Abies grandis (Dougl.) Lindl., Larix occidentalis Nutt., Pinus contorta var. latifolia (Engelm.), Pinus...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:: Lewis, Katherine JoAnn
Abstract:: The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

RFLP analysis of genetic variation in the laminated-root-rot fungal pathogen of conifers, Phellinus weirii

Creator:: Bae, Hanhong
Abstract:: DNA markers that detect polymorphisms within and between two biological species of the coniferous laminated-root-rot fungus Phellinus weirii were developed and used to measure the amount and distribution of genetic variation. In a preliminary survey, total cellular DNA from 3 Douglas-fir-type isolates and 3 cedar-type isolates was digested with 12...
