Despite the belief that fuels management, a form of prescribed fire that reduces accumulated fuels in commercially thinned forests, is necessary to restore forest 'health' in the Pacific Northwest, its effects on wildlife has received little attention in the scientific literature. Because fuels management is supported, funded, and implemented nationwide...
The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...
Pyrenophora tritici-repentis, the causal agent of tan spot disease of wheat, mediates disease by the production of host-selective toxins (HST). The known toxins are recognized in an 'inverse' gene-for-gene manner, where each is perceived by the product of a unique locus in the host and recognition leads to disease susceptibility....

To assess the conversion and embedment of yttrium nitrate to yttrium oxide using selective laser melting, a thermodynamic approach for laser power and scan speed predictions on surface temperature, recoil pressure, and resulting track morphology window are employed. Inkjet printing is used to deposit the liquid film of yttrium nitrate...
Emerging applications for robotic data collection include ocean monitoring, emergency response and urban search and rescue. At the core of these applications is a robot's ability to make informed decisions on incomplete data. This dissertation addresses this problem by developing novel techniques for modeling and estimating structured environments using deep...
Local property-owning residents maintain high levels of interest
and awareness regarding a neighboring natural resource complex.
Factors, however, such as proximity, personal interests, use patterns
and economic considerations cause local inhabitants to have an
inaccurate perception of the natural resource complex. The nature
of local resident perception can be analyzed...
