Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Banks, Gardens and Bees: Enhancing Community Resilience in West Africa

Creator:: Polasky, Sophia
Abstract:: International development programs are often implemented with the goal of building community resilience, but without a clear articulation of how this goal will be met, or any consideration of if or why the effort was successful after it has concluded. This thesis considers three different activities implemented by the U....

Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

Creator:: King, Ryan M.
Abstract:: Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

Wood-Rotting Fungal Pigments as Colorant Coatings on Oil-Based Textile Dyes: A Detailed View of the Interaction between Fungal Pigments and Some Commercial Fabrics

Creator:: Palomino Agurto, Mardonio
Abstract:: Natural dyes have been used to color textiles for centuries, but with the shift to mass production, the use of synthetic dyes has increased due to their lower cost and easy manufacturing volume. However, synthetic dyes (such as disperse blue dyes 106 and 124) have been reported to cause skin...

Multi-Scale Study of Ember Production and Transport under Multiple Environmental and Fuel Conditions

Creator:: Hudson, Tyler R.
Abstract:: Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

Creator:: Loughran, Ryan P.
Abstract:: We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

Comparing Random and Nonrandom Spatial Patterns of Artifacts within Lithostratigraphic Unit 3 at Cooper’s Ferry, Idaho

Creator:: Gregory, Alex R.
Abstract:: Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
