Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...
Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...
Textiles (including basketry, cordage, woven, knotted, or plaited products) make up a considerable portion of the perishable archaeological record in dry caves of the northern Great Basin region, much of which is created from plants and plant fibers. The archaeological study of precontact textiles greatly informs our understanding of how...
Climate change has the potential to accelerate many forms of human migration and mobility, yet almost all of the key migration outcomes of interest are determined predominantly by governance, or the norms, laws, and institutions involved in the coordination of human society. These outcomes include the decision whether or not...
Pacific whiting (Merluccius productus) is one of the most abundant fisheries on the American west coast. However, these fish are historically underutilized due to quality issues resulting from fillet softening that occurs as a result of both endogenous and exogenous (Myxosporidian parasite infection) cathepsin protease action during either storage (cathepsin...
The Klamath River Basin (KRB) is one of the most contested basins of the Western U.S. with respect to water. Multiple stakeholders, including Tribes, farmers, state and federal agencies, and environmental advocates, are in frequent conflict over water rights and water use. Removal of the four hydroelectric dams is one...
Kelps are large brown algae in the order Laminariales and are foundation species that form the basis of kelp forests. Present across a quarter of the world’s coastlines, kelp forests provide diverse services to coastal communities, as habitat for commercially and culturally important species, as a food source for humans...
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...
Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...
Utilizing anti-racist feminist research methodologies, Making Sense of Social Justice Education: A Case Study of the Difference, Power, and Discrimination Program, argues that institutions of higher education must attend to local histories of student activism and faculty development in their efforts to create social justice-informed structural change. Increasingly colleges and...
This thesis is an IRB-exempt oral history focused on the non-profit Corvallis Multicultural Literacy Center (CMLC) in Corvallis, Oregon. The CMLC, formerly on 9th Street, was known to many community members as the Yellow House. The Yellow House was a dedicated community-based space where people of all cultures could come...
This study explores the role of emotions in extensive hydraulic projects that become part of nation-state building processes and have transboundary impact. The main objective is to investigate how political leadership uses emotional narratives to foster water nationalism in the case of the Southeastern Anatolian Project (GAP) in Turkey. The...
Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...
Explosively erupting volcanoes and megathrust earthquakes (Mw 8+ magnitude) occur at subduction zones and adjacent volcanic arcs. Volcanic eruptions are observed occurring close in time to megathrust earthquakes in the historical record from at least the 18th century CE to present in locations globally, including Japan in 1707 CE (Chesley...
Successful cryopreservation of all biological specimens would have an untold positive impact on medicine and scientific research. However, cryopreservation of the most complex biological specimens, such as tissues and organs, remains elusive. Vitrification, or ice-free cryopreservation, is promising for cryopreservation of complex specimens. The biggest challenge, though, is the toxicity...
Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...
We are witness to an ever tighter coupling between natural hazard-related disasters ("disasters") and violent social conflict ("conflict"). Previous research has established that disaster has the propensity to lead to conflict, and conflict, in turn, has been found to contribute to disaster vulnerabilities. The field of disaster diplomacy, by contrast,...
Developers spend a considerable amount of time comprehending code and building accurate mental models of the code. Understanding the relationships between software features within IDEs is difficult, with information split across different visual hierarchies making navigation cumbersome. Canvas-based IDEs mitigate some of the navigation costs by allowing relevant information to...
With the increasing international focus on transboundary cooperation as a part of the Sustainable Development Goal (SDG) Framework, there is global recognition of transboundary water cooperation as a tool for improved governance and management of transboundary surface and groundwaters. Yet, there is not an agreed upon definition of transboundary water...
