Fungi-Derived Pigments for Sustainable Organic (Opto)Electronics

Creator:: Gieshers, Gregory, Van Schenck, Jonathan, Gutierrez, Sarath Vega, Robinson, Sara, and Ostroverkhova, Oksana
Abstract:: We present on the optical and electronic properties of a fungi-derived pigment xylindein for potential use in (opto)electronic applications. Optical absorption spectra in solutions of various concentrations and in film are compared and are consistent with aggregate formation in concentrated solutions and films. In order to improve film morphology obtained...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Fish for the Future: Fisheries Conservation Developments and Lessons Learned from Squaxin Tribal, and Washington State, Salmon Fisheries Management

Creator:: Peters, Joseph C.
Abstract:: Washington State fisheries and Washington State Treaty Tribes are becoming increasingly restricted in harvest of wild salmon due to US Endangered Species Act listings of salmon species, marine mammal predation by both ESA listed Southern Resident Killer Whale (SRKW) and US Marine Mammal Protection Act protected pinnipeds, salmon habitat destruction,...

Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Marshall, Kristin N., Shelton, Andrew O., Matkin, Craig, Burke, Brian J., and Ward, Eric J.
Abstract:: Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species of pinnipeds and killer whales (Orcinus...

Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...

Fungal Photonics

Creator:: Spafford, Jasper
Abstract:: The spalting fungus Scytalidium cuboideum secretes a red pigment that produces naphthoquinonic crystals that are a photonic material candidate. The molecule can pack together in different configurations resulting in amazingly different optical properties. I developed a procedure (slowly evaporating the solvent) to preferentially grow two of these configurations, which have...

Recovery of ectomycorrhizal fungus communities fifteen years after fuels reduction treatments in ponderosa pine forests of the Blue Mountains, Oregon

Creator:: Hart, Benjamin T. N., Smith, Jane E., Luoma, Daniel L., and Hatten, Jeff A.
Abstract:: Managers use restorative fire and thinning for ecological benefits and to convert fuel-heavy forests to fuel-lean landscapes that lessen the threat of stand-replacing wildfire. In this study, we evaluated the long-term impact of thinning and prescribed fire on soil biochemistry and the mycorrhizal fungi associated with ponderosa pine (Pinus ponderosa)....

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...

An Investigation into the Time-Sensitive Color Changing Quality of the Pigment Extracted from Scytalidium ganodermophthorum

Creator:: Walsh, Zielle
Abstract:: Scytalidium ganodermophthorum (Xylogone ganodermophthora) is known as a yellow-pigmenting spalting fungus. However, recent observations have indicated that the dichloromethane-extracted pigment produced by S. ganodermophthorum can vary in color from yellow to green to red to purple, depending on the age of the fungus at harvesting. The timeline and mechanisms behind...
