The gravitational component of water potential and frictional resistance during transpiration lead to substantial reductions in leaf water potential (Ψl) near the tops of tall trees, which can influence both leaf growth and physiology. We examined the relationships between morphological features and gas exchange in foliage collected near the tops...
Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...
We designed a concise way to store and manipulate GIS coverage data in a geospatial database. Our
geospatial database is implemented with PostgreSQL and PostGIS. PostgreSQL is an object-relational
database, and PostGIS supports various geospatial operations as an SQL extension. In our Oregon
Relational Spatial Topology (ORST) approach, topological relationships...
3D datasets acquire great importance in the context of medical imaging. In this thesis we survey and enhance solutions to problems inherently associated with 3D datasets-processing time,noise and visualization. Efforts include development of a tool kit to provide a multi-threaded processing platform to cut processing time, produce real time visualization...
Whether microevolutionary processes can explain macroevolutionary patterns has long been a matter of contentious debate. The debate has persisted largely because of the challenging task of connecting microevolutionary theory, which examines population-level phenomena on the generation scale, to data collected across larger spatial and temporal scales. My dissertation research broadly...
1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.

Background
Feline injection-site sarcoma (FISS) is a rare and aggressive tumor associated with vaccines, drug injections, and skin trauma in cats. The understanding of FISS remains limited, posing challenges in its diagnosis, treatment, and prevention. In this study, we analyzed the differential expression of miRNAs and their target genes in...
Several programming languages define a virtual machine that can be implemented as an interpreter. The interpreter runs more slowly than the real machine. In order to maintain a portable virtual machine for X2 and still achieve acceptable performance, our work compiles X2 procedures into native machine code so that the...
This thesis examines the student employment experience within the field of higher education through an auto-ethnographic lens. The factors that contribute to the overall well-being and success of student employees in higher education are explored. The literature related to the student employment experience is limited, with much of the data...
The hermit thrush (Catharus guttatus) and the varied thrush (Ixoreus naevius) are focal species for conservation of forested habitats in Oregon. Although habitat associations have been defined for both species, their response to changes in vegetation following wildfire has not been well studied. To help fill this information gap, I...
