Chloroplast DNA variability and phylogeny in the California closed cone pines

Creator:: Hong, Yong-pyo, 1958-
Abstract:: Chloroplast DNA (cpDNA) variability and phylogeny were studied via analysis of restriction site mutations and DNA sequencing in a complex of three closely related species of pines: Pinus radiata D. Don, P. attenuata Lemm., and muricata D. Don. Genomic DNA from 384 trees representing 20 populations in the complex were...

Likelihood analysis of the multivariate ordinal probit model for repeated and spatial ordered categorical responses

Creator:: Li, Yonghai
Abstract:: This dissertation is about the likelihood analysis of ordered categorical responses in a longitudinal/spatial study, meaning regression-like analysis when the response variable is categorical with ordered categories, and is measured repeatedly over time or space on the experimental or sampling units. Particular attention is given to the multivariate ordinal probit...

The Application of Linear Programming for Forest Land Use and Timber Management Planning with Watershed Considerations in Terengganu, Peninsular Malaysia

Creator:: Mat Isa, Ahmad Zainal
Abstract:: The purpose of this paper is to illustrate the use of Linear Programming (LP) and other mathematical procedures to evaluate watershed and perpetuity constraints on forest land use for a selected scenario in Terengganu, Peninsular Malaysia. The paper describes the system of modelling and forecasting estimates of potential timber growth,...

Performance of cultivars, hybrids and composites of winter wheat (Triticum aestivum L. em Thell) grown at three locations

Creator:: Verges, Ruben P.
Abstract:: The objective of this study was to compare three genetically different groups of winter wheat for their grain yield. Experimental material consisted of parental lines grown in pure stands, hybrids, and 1:1 mixtures of the parental combinations. Three sites were employed to evaluate possible interactions between the different groups across...

Phytosociology of the ponderosa pine type on pumice soils in the Upper Williamson River Basin, Klamath County, Oregon

Creator:: Volland, Leonard A.
Abstract:: The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...

An ecological reconnaissance of the artemisia steppe on the east central Owyee uplands of Oregon

Creator:: Culver, Roger Norman
Abstract:: As the management of range lands is intensified or as improvement activity is increased, a critical need is seen to refine the understanding of the ecology of these lands. If soil surveys on range lands are to be meaningful and useful, the relationship between the fundamental ecological units and the...

Improving Region-Scale Landslide Inventory and Susceptibility Mapping

Creator:: Bunn, Michael D.
Abstract:: Landslides are a natural hazard that have major societal, economic, and environmental impacts. The understanding of landslides begins with the observation that they are a spatial problem. Spatial relationships have historically been explored with maps, and landslides are no different. Such maps range in focus from inventory maps, which identify...

An Experimental and Analytical Investigation of the Parameters that Influence Measured CO₂ in Plagioclase-Hosted Melt Inclusions in MORBs

Creator:: Drignon, Melissa J.
Abstract:: To understand the processes that lead to the formation of the oceanic crust, one must know the composition and the depth at which primary melts originate. Towards this end, this dissertation focuses on plagioclase-hosted melt inclusions from plagioclase ultraphyric basalts (PUBs). Plagioclase is usually considered to be the second phase,...

Dynamics and control of continuous crystallizers

Creator:: Leu, Lii-ping
Abstract:: The theoretical analysis of an unseeded, isothermal mixed-suspension mixed-product-removal (MSMPR) crystallizer with a fines trap is developed. The lumped parameter system equations are presented for a homogeneous nucleation and a number-dependent secondary-nucleation model. Linear stability analysis and system simulations are used to investigate the system's dynamic behavior. Modal control algorithms...

Rhyolitic magmatism of the High Lava Plains and adjacent Northwest Basin and Range, Oregon : implications for the evolution of continental crust

Creator:: Ford, Mark T.
Abstract:: Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
