Fault behavior over geomorphic time scales in the Pakistan Himalaya, Kashmir Himalaya, and California

Creator:: Madugo, Christopher Lee Madden
Abstract:: The state of the knowledge for fault behavior in the northwest Himalaya and California varies dramatically. In the Pakistan and Kashmir Himalaya, few data constrain the role that individual active faults play in accommodating Indo-Eurasian convergence and the relative earthquake hazard across the region. By contrast, the San Andreas fault...

Economic Benefit from Allowing Wildfires to Burn in Federal East-Side Cascade Forests

Creator:: Gagnon, Aaron R.
Abstract:: In this thesis I examine the question: can allowing a wildfire to burn this year result in a net positive economic gain? To answer this question I created 2,500 multiple sets of paired scenarios (called a fire of interest) which consist of ignitions, vegetation growth, and timber harvest over the...

Understanding invasive conifer seed structure and viability to inform treatment efforts

Creator:: Vautrin, Andy
Abstract:: This paper examines the invasion of exotic wilding conifers on the native tussock grasslands of Aotearoa New Zealand. The investigation includes two studies and aims to better understand the structure of Pinus contorta seeds across tree crown positions and the viability rates of P. contorta seeds produced during a trees...

Mechanisms of uptake and some factors influencing the toxicity of 2-chloro-2', 6'-diethyl-N-(methoxymethyl) acetanilide (alachlor) for selected plant species

Creator:: Groenwold, Bareld Egge, 1939-
Abstract:: A number of studies with ¹⁴C-labeled 2-chloro-2', 6'-diethyl- N-(methoxymethyl) acetanilide (alachlor) were conducted to obtain information about the mechanisms of uptake of this herbicide. In other studies, technical alachlor as well as the emulsifiable concentrate formulation of the chemical were used to investigate the effect of several factors on the...

Demography, home range, and habitat selection of northern spotted owls in the Ashland Watershed

Creator:: Schilling, Jason W.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) inhabit productive forests that historically supported frequent, large, variable-severity fires in the Klamath province of southwestern Oregon occur in complex. The potential for high-severity wildfire remains high throughout this region, so remaining spotted owl habitat is at risk. An adaptive management approach to fire...

Assessing biaxial strength characteristics of wood-based structural panels

Creator:: Cheng, Ping, 1960-
Abstract:: Biaxial strength characteristics of wood-based structural panels were evaluated by using analytical and experimental methods. Cruciform plywood specimens were tested under biaxial tensile-tensile, compressive-compressive loadings in a symmetrically-jointed- arm test fixture, which was mounted on a universal testing machine. Performance of the test fixture was also evaluated during the tests....

Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

Creator:: Riddell, Audrey P.
Abstract:: Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

Logging planning, felling, and yarding costs in five alternative skyline group selection harvests

Creator:: Edwards, Richard M.
Abstract:: Alternative silvicultural systems, such as group selections, have recently come into vogue in the U.S. Pacific Northwest in response to political and public pressure against traditional, even-aged silviculture. There is also interest in silvicultural systems for multiple resources. Little is known about planning logistics, operational requirements, and harvest costs for...

60 years of avian community change in the Willamette Valley, Oregon

Creator:: Curtis, Jenna
Abstract:: Birds perform valuable ecological functions and are useful environmental indicators. Avian distributions and diversity are predicted to change over the next 50 years. Little information exists on the role of local and regional conditions in fluctuations of avian communities over time. Historic datasets present a legacy of information that helps...

The role of acoustical signals in the communicative behavior of the water scavenger beetles, Tropisternus (Coleoptera:hydrophilidae)

Creator:: Ryker, Lee Chester
Abstract:: The communicative behavior of five species and subspecies of Tropisternus Solier (Coleoptera: Hydrophilidae) was studied. These aquatic beetles have stress and calling chirps (both sexes), a second male calling signal (one species), a single male courtship sound (usually), a male copulatory sound, and a female aggressive rejection buzz (three species)....
