The response to various levels of stand density by natural Douglas-fir regeneration,
shrub and sprouting hardwood species was studied in the mixed-evergreen-forests of
southwest Oregon. Partial-cut old growth (harvested 22-31 years prior) and thinned evenaged (harvested 9-17 years prior) stand types were used as surrogates for intentionally managed uneven-aged stand...
Since the Altman Z-score was published in 1968, the Z-score has been a common way that investors predict bankruptcy and value risk. However, corporate structure has evolved since 1968 due to changes in economic factors and financial reporting standards. In 1976, the FASB created the first bright-line rules to distinguish...

Sudden oak death is caused by the clonally reproducing generalist oomycete Phytophthora ramorum. The pathogen can infect more than 130 different plant hosts including Quercus spp., Larix kaempferi, and Notholithocarpus densiflorus, as well as common nursery genera such as Rhododendron and Camelia, where it causes symptoms ranging from bleeding cankers...
River impoundment by dams, along with other human driven changes, has threatened the health of riparian forests in the northern Great Plains for much of the last century. Two major concerns in the region are the impediment of natural recruitment of plains cottonwood (Populus deltoides Marsh. subsp. monilifera (Ait.) Eckenw.)...
Host-parasite interactions between the pathogen, Sphaerulina musiva, and its host, Populus spp., were examined in a series of studies. In the first study, variation in resistance of Populus nigra from 7 locations in Europe was differentiated based on the parameters cankers per cm and disease severity score. The analysis evaluated...
Sphaerulina musiva is a fungal pathogen that causes Septoria leaf spot and stem canker on susceptible Populus species and hybrids. In this thesis, host and pathogen contributions to Septoria stem canker disease were explored through: 1) a greenhouse study associating Septoria stem canker phenotypes with molecular markers from a genetic...
Steel wire rope is used for many logging applications. This material has served the
logging industry well in terms of strength, durability, and longevity; Steel wire rope is
difficult to use because of properties that make it stiff, heavy; and unyielding. These same
properties cause fatigue, exhaustion, and may contribute...
