Landscapes Of Exclusion: Mapping Racial Boundaries And Environmental Burdens, Monique A. Baxter
Landscapes Of Exclusion: Mapping Racial Boundaries And Environmental Burdens, Monique A. Baxter
2026 Symposium
Inspired by the author’s work with the mapping team for the Eastern Washington University Racial Covenants Project, this project uses additional GIS layers to reveal the enduring imprint of historic racial exclusion on today’s urban landscape. Spokane, Washington’s landscape, like many urban areas across the country, bears the imprint of racial exclusion through mechanisms such as restrictive covenants and redlining. This project examines how racial covenants and red lining layers relate to current brownfield and superfund sites to shape Spokane’s long-term environmental injustice. Using digitized property records, historic zoning maps, and GIS spatial analysis, this project demonstrates that historically red …
Are There Enough Bees? Assessing Pollen Limitation In Native Eastern Washington Prairie Forbs, Alejandro Torres
Are There Enough Bees? Assessing Pollen Limitation In Native Eastern Washington Prairie Forbs, Alejandro Torres
EWU Masters Thesis Collection
Prairie ecosystems in eastern Washington have been severely degraded due to agricultural intensification, urbanization, and habitat fragmentation, leaving less than 0.1% of native prairie intact. As a result, these ecosystems have become some of the most endangered in the United States. One group of essential pollinators is the bees, which facilitate plant reproduction and contribute to the long-term persistence of restored plant communities. However, despite the presence of at least 257 native bee species in the region, the impacts of habitat fragmentation and restoration on pollinator activity and plant-pollinator networks remain poorly understood. For this study, we worked across Eastern …
Assessing Arbuscular Mycorrhizal Fungal Community Composition And Diversity Across A Land-Use Gradient In Eastern Washington Prairies, Katherine I. Cole
Assessing Arbuscular Mycorrhizal Fungal Community Composition And Diversity Across A Land-Use Gradient In Eastern Washington Prairies, Katherine I. Cole
EWU Masters Thesis Collection
Arbuscular mycorrhizal fungi (AMF) are key to healthy, functioning terrestrial ecosystems worldwide. Associating with over 80% of all extant land plants, they play a pivotal role in nutrient cycling, and contribute to overall plant health. Given their significance to terrestrial ecosystems, AMF have a crucial role to play in the successful restoration of Eastern Washington’s native prairies. However, AMF community composition is significantly altered by the commercial agricultural practices used extensively in this region for over 100 years. The Eastern Washington University (EWU) Prairie Restoration Project aims to restore ~120 acres of farmland to native prairie. This research provides insight …
Fairy Shrimp (Anostraca) In The Vernal Pools Of Eastern Washington, Megan Garvey
Fairy Shrimp (Anostraca) In The Vernal Pools Of Eastern Washington, Megan Garvey
EWU Masters Thesis Collection
Vernal pools are ephemeral wetlands that retain water annually from winter and spring precipitation and snowmelt but are dry the rest of the year. Though important habitats and sources of freshwater biodiversity, they are little accounted for in wetland conservation and restoration practices. Like much of the world’s wetlands, they have seen a significant decline from anthropogenic impacts and conversion for alternative land use. Pools are also at significant risk due to the impacts of climate change and invasive species. These small temporary water bodies perform vital ecosystem services and are host to rare and endemic species. Anostraca, or fairy …
Examining The Effects Of Seed Mix Diversity And Composition, Biochar Application, Seeding Rate, Species Identity, And Topography On Palouse Prairie Restoration, Thurman Johnson
EWU Masters Thesis Collection
With over 99.9% of the Palouse prairie lost to land conversion, restoring native plant communities is crucial for ecological function, however, research on Palouse prairie restoration methods is sparse. Seed-based restoration uses a mix of seeded species to enhance competition against weeds, diversify vegetation, and adapt to environmental conditions. However, many factors can be varied, such as seed mix diversity and composition, the proportion of forbs to grasses, and seeding rate, and the most effective levels of each are not clear. Further, soil amendments, such as biochar, may benefit properties of tilled soils, but have not explored in Palouse Prairie …
Differentiating The Effects Of Two Non-Native Fish In The Turnbull National Wildlife Refuge, Sarah Richardson
Differentiating The Effects Of Two Non-Native Fish In The Turnbull National Wildlife Refuge, Sarah Richardson
EWU Masters Thesis Collection
This study seeks to determine the individual effects of two non-native fish, the brook stickleback, Culaea inconstans, and pumpkinseed, Lepomis gibbosus, on the aquatic invertebrates and food webs of Turnbull National Wildlife Refuge (TNWR). Ten ponds were analyzed and compared with stable isotope analysis and invertebrate abundance data. Three ponds were chosen to represent each of the following categories: fishless, brook stickleback invaded (BS), and coinvaded, along with a single pumpkinseed (PS) pond. Overall, δ[superscript]13C and δ[superscript]15N values increased in invaded ponds, indicating shifts in the zooplankton community structure and the carbon source of predatory invertebrates. Mean δ[superscript]13C was the …
Remnant Assessment And Soil Inoculation To Inform Large-Scale Prairie Restoration At Eastern Washington University, Erik E. Peterson
Remnant Assessment And Soil Inoculation To Inform Large-Scale Prairie Restoration At Eastern Washington University, Erik E. Peterson
EWU Masters Thesis Collection
The Palouse Prairie of Eastern Washington and Western Idaho, characterized by rolling hills of deep loess soil, is one of the most endangered ecosystems in the world, with more than 99% converted to tilled farmland. To mitigate this loss, Eastern Washington University has begun prairie restoration on a tilled wheat field adjacent to campus, in the northern extent of the Palouse Prairie Ecoregion. However, effective restoration requires understanding reference conditions, and there are relatively few studies of remnant prairie plant communities or soils, particularly in the Northern Palouse. From north to south in the Palouse Prairie Ecoregion, there are gradients …
Effects Of Beaver Dam Analogs On Stream Ecosystem Function Of Crab Creek, Washington State, Nicholas D. Broderius
Effects Of Beaver Dam Analogs On Stream Ecosystem Function Of Crab Creek, Washington State, Nicholas D. Broderius
EWU Masters Thesis Collection
This study documents the effects of beaver dam analogs (BDAs) on nutrient transport, fish community composition, macroinvertebrate drift, and benthic macroinvertebrate communities of Crab Creek, WA, USA. In 2019, the U.S. Fish and Wildlife Service (USFWS), and Natural Resource Conservation Service (NRCS) placed 25 BDAs in Crab Creek on a section of private land near Harrington, WA. Beaver dam analogs are structures placed in streams to mimic the ecosystem effects of beaver activity and are increasingly used as a stream restoration technique. The primary goals of placing these BDAs in the stream was to impound sediment and create a new …
Preliminary Microbiome Analysis Of Freshwater Bivalves From Turnbull National Wildlife Refuge, Dechen Edwards
Preliminary Microbiome Analysis Of Freshwater Bivalves From Turnbull National Wildlife Refuge, Dechen Edwards
2020 Symposium Posters
Eukaryotic hosts and their associated microbes exhibit variable relationships. Some are driven by well-documented benefits including microbial contributions to host digestion; others are less understood. In this project, we seek to understand how a host’s microbiome is differentiated from the surrounding, free-living microbial community and whether this process is altered by the presence of pollution. Here we present a protocol developed for the extraction, isolation, and identification of the microbial population found in freshwater “fingernail” clams (Sphaeriidae) based on modified methods from the Earth Microbiome Project and studies of freshwater amphibian and marine bivalve microbiomes. We first developed …

Effects Of Non-Commercial Thinning On Great Horned Owls On Turnbull National Wildlife Refuge, Christopher P. Brady
EWU Masters Thesis Collection
To sustain forest health, increase species diversity and reduce wildfire events in the ponderosa pine (Pinus ponderosa) forests of at Turnbull National Wildlife Refuge (TNWR) managers have implemented a variety of approaches including prescribed burning and non-commercial thinning. The impacts of thinning on owl species diversity and habitat occupancy have not been studied in these ponderosa pine forests. My study had the following objectives 1) compare forest stand metrics between treatment plots, 2) compare owl species richness between treatment plots, 3) examine if occupancy and detection patterns of Great Horned Owls varied with forest condition and season, respectively, and 4) …

Vocalizations Influence Roost-Site Selection In Overwintering Cavity-Nesting Birds In Eastern Washington, Shelby M. Hunter
Vocalizations Influence Roost-Site Selection In Overwintering Cavity-Nesting Birds In Eastern Washington, Shelby M. Hunter
EWU Masters Thesis Collection
Primary cavity-nesting birds are keystone species because the annual tree cavities they excavate become critical habitat for other species. In eastern Washington, most primary cavity-nesting birds are year-round residents. They increase overwinter survival by night roosting in cavities and forming flocks. The timing of roost site selection can impact the quality of a roost site, thus selecting a roost site too late reduces the odds of selecting the most favorable microclimate available. Birds in flocks use alarm calls to warn of threats and contact calls to promote group cohesion. My study asks if timing of roost site selection and vocalizations …
Determining The Effects Of Non-Native Brook Stickleback (Cualea Inconstans) On The Lentic Systems At Turnbull National Wildlife Refuge, Cheney, Wa, Jenae N. Yri
EWU Masters Thesis Collection
"The introduction of non-native fishes can cause trophic cascades in freshwater habitats; these effects may be amplified in ephemeral/temporary habitats. Non-native brook stickleback fishes (Culaea inconstans) were first documented on the Turnbull National Wildlife Refuge (WA) in 1999 and are now present in many portions of the refuge. The consequences of their presence on the refuge's perennial/permanent and temporary habitats are poorly understood. Therefore, the purpose of my project was to determine if brook stickleback are affecting habitat characteristics that are important for waterfowl nesting success. From April-August 2015, I compared the macro invertebrate and macrophyte community characteristics, fingernail clam …
Invertebrate Drift In The Upper Columbia River With Implications For Young-Of-The-Year White Sturgeon, Ryan W. Reihart
Invertebrate Drift In The Upper Columbia River With Implications For Young-Of-The-Year White Sturgeon, Ryan W. Reihart
EWU Masters Thesis Collection
"White sturgeon (Acipenser transmontanus) in the upper Columbia River have been in decline for over 60 years and are listed as critically endangered by the International Union for Conservation of Nature. Annual spawning produces dispersing larvae; however, recruitment into the juvenile age class has not occurred since the early 1970s. One hypothesis to explain this failure in recruitment is that larvae may not find adequate prey. Little is known about diet and prey availability for white sturgeon larvae, especially in Lake Roosevelt, a reservoir of the Columbia River. The Spokane Tribe of Indians collected littoral and mid-channel benthic drift samples …
Phenotypic Characterization Of The Peach (Prunus Spp.) Collection At The National Clonal Germplasm Repository In Davis, California, Tim Moran
EWU Masters Thesis Collection
"Germplasm repositories are an invaluable resource for the collection and preservation of important living genetic material, and provide a multitude of research opportunities for crop improvement. Advances in genomics research have created an urgent demand for phenotypic data in order to assist researchers in identifying relationships between genetic makeup and phenotypic variability. The peach, Prunus persica, is an important economic crop species that is heavily bred and cultivated. In peach, specific tree growth habits are used in breeding to select for tree architectures that may provide growers with more options for orchard design and cultural practices. The presence of extrafloral …

Lepeophtheirus Salmonis, Parasitizing Three Species Of Pacific Salmon (Oncorhynchus Spp.): Host Variations In Load, Morphology, Fecundity, And Genetics Of The Salmon Louse, Stephen Flanagan
EWU Masters Thesis Collection
"The purpose of this study is to determine biological parameters of salmon lice (Lepeophtheirus salmonis) as they parasitize different species of Pacific Ocean salmonids off the north Pacific coast of Washington State. Parasite load counts of L. salmonis were made and individuals were collected from salmonids in their natural environment. Louse morphology and fecundity were examined using microscopy. Parasite loads were equal between different species of salmonids (p = 0.231). Lice that infected chinook salmon (n= 48) were smaller in total body length (p < 0.001), cephalothorax length (p < 0.001), and cephalothorax width (p < 0.001) when compared to lice that infected coho salmon (n = 44) or pink salmon (n=45). Lice that infected coho and pink salmon were not statistically different in body length (p = 0.213), cephalothorax length (p = 0.996), or cephalothorax width (p = 0.149). Also, L. salmonis produced fewer eggs when infecting chinook salmon (n = 24) than when infecting coho salmon (p < 0.001) or pink salmon (p < 0.001). Whereas, lice that infected coho salmon (n = 41) or pink salmon (n = 22) produced similar number of eggs (p = 0.60). These results indicate that there are factors associated with infecting chinook salmon hosts that reduce the size and fecundity of salmon lice"--Document.
Riparian Understory Dynamics And Relationship To Dams On The Elwha River, Washington, Aaron J. Clausen
Riparian Understory Dynamics And Relationship To Dams On The Elwha River, Washington, Aaron J. Clausen
EWU Masters Thesis Collection
"Dams alter the dynamics inherent to river systems by displacing natural hydrologic and sediment regimes, which can fundamentally alter riparian ecosystem function. However, with better understanding of how dams negatively impact river systems, and as many dams approach the end of their lifespan, dam removal is being used to facilitate ecosystem restoration. Whereas researchers have successfully illustrated the negative impacts dams have on biological communities, the long-term ecological implications of dam removal are not well understood. At present, two dams are being removed along the Elwha River (Washington, USA), providing a valuable window for ecological studies concerning the effects of …
