Lichens Of Iller Creek: A Checklist For The Iller Creek Unit, A Division Of Dishman Hills Conservation Area, Spokane Valley, Wa, Devin M. Mumey, Giovanna Bishop, Jessica L. Allen
2023 Symposium
The field of biodiversity documentation encompasses a broad range of research including new species discovery and description, compilation of species present in a given area, and investigation of interspecies interaction. In an era of increasingly devastating and rapid environmental change, documenting biodiversity has become increasingly important. Anthropogenic effects on urban-adjacent natural areas are especially significant, as they can cause numerous, often drastic, responses in ecosystems. Our objective here was to document the lichen biodiversity in a large urban-adjacent protected area: the Iller Creek Unit of the Dishman Hills Conservation Area in Spokane Valley, Washington. This unit encompasses a diversity of …

Developing Cryopreservation Methods Of Wheat Roots, Ramanpreet Singh, Nguyen Khoi Nguyen, Taylor S. Matteucci
2023 Symposium
In the midst of record breaking rates of plant species extinction due to climate change and fungal diseases, a universal cryopreservation method would provide a means for preservation of these many different species. The concept of plant root cryopreservation first emerged in the late 1960’s, and with it came new avenues of preserving tissue for the purposes of agriculture and research. Frozen tissues can be transported and stored more reliably than other more conventional means. When thawed, they have the potential to be cultured and grown. Several different methods of cryopreservation exist. This experiment used the Fast (3°C/minute) and Slow …

Canine testes thin section culture
Testes tissue culture systems would provide a tool to elucidate spermatogenesis mechanisms, with the aim of genetic preservation of mammals, especially endangered species. Our experiment aims to develop a culture system capable of producing viable mammalian sperm cells in vitro.
Dogs were chosen as the model organism because testes are readily available. Canine testes were obtained from a local veterinary clinic. Thin sections were generated using a commercial electric slicer. They then were cleaned using Dulbecco’s Phosphate-Buffered Saline (DPBS) supplemented with antibiotics then cultured in a modified Tissue Culture Medium 199 (TCM-199). Sections were …

A Baseline Assessment Of Migratory And Resident Bird Use Of A Prairie Restoration Site In Eastern Washington, Madilyn J. Odiorne, Brynn A. Richey, Ruby L. Hammond
A Baseline Assessment Of Migratory And Resident Bird Use Of A Prairie Restoration Site In Eastern Washington, Madilyn J. Odiorne, Brynn A. Richey, Ruby L. Hammond
2023 Symposium
Prairies, and other types of grassland ecosystems, have suffered some of the most profound losses worldwide, due to anthropogenic factors such as fossil fuel extraction, agriculture, and climate change. Likewise, organisms inhabiting grassland ecosystems have become extirpated across much of their historical range, not the least of which has been a 50% decline in grassland birds since the 1960s. In response to losses of intact prairie in eastern Washington, a 120-ac site has been established on the EWU campus to regenerate native prairie and monitor changes in the ecosystem as native plants recolonize and replace non-natives. Because birds are an …
Confidence And Exercise: Is There A Link Between Exercise And Percieved Confidence?, Jocelyn I. Simpson, Tatum R. Dickison
Confidence And Exercise: Is There A Link Between Exercise And Percieved Confidence?, Jocelyn I. Simpson, Tatum R. Dickison
2023 Symposium
High self-confidence is crucial in social, work, and academic settings. Previous research suggests that individuals with greater confidence tend to be healthier and happier. (ŞAHİN et al., 2016).
PURPOSE: To investigate whether exercise intervention (resistance training (RT), aerobic training (AT), no exercise (NE)) could increase perceived confidence levels before an academic test. It was hypothesized that participants who exercised before the test would have higher perceived confidence levels compared to those who did not.
METHODS: Eastern Washington University students (n=18, 12 males), between the ages of 18-40 were recruited. Participants were randomized into one of the interventions (AT, RT, NE). …
Overexpressing Two Helicobacter Pylori Small Rnas From A Bacterial Pathogenicity-Related Chromosomal Region To Investigate Their Regulation Of Virulence Genes, Roxanne N. Mcpeck, Olivia F. Morgan, Andrea R. Castillo Phd
Overexpressing Two Helicobacter Pylori Small Rnas From A Bacterial Pathogenicity-Related Chromosomal Region To Investigate Their Regulation Of Virulence Genes, Roxanne N. Mcpeck, Olivia F. Morgan, Andrea R. Castillo Phd
2023 Symposium
The bacterial pathogen Helicobacter pylori infects the stomachs of approximately 50% of humanity, causing symptomatic disease (e.g., stomach ulcers, gastric cancer, and MALT lymphoma) in 10-15% of the infected. Colonizing the acidic, inhospitable stomach requires H. pylori to tightly regulate gene expression despite lacking many common bacterial genetic regulatory elements. The pathogen may compensate by using abundant non-protein-coding small RNAs (sRNAs) to regulate gene expression, including of infection-intensifying virulence genes. Additionally, severe disease and cancer correlate with infection by H. pylori strains that contain a nonessential chromosomal region, the cytotoxin-associated gene pathogenicity island (cagPAI). This encodes powerful virulence …
Estimating The Minimum Number Of Individuals (Mni) For Skeletal Collections With Consideration To The Introduction Of Procurement Bias, M. Elizabeth Dyess, T. Heil
Estimating The Minimum Number Of Individuals (Mni) For Skeletal Collections With Consideration To The Introduction Of Procurement Bias, M. Elizabeth Dyess, T. Heil
2023 Symposium
Of the competing methods for the estimation of the number of individuals represented within a skeletal assemblage, variations of the calculation of MNI (Minimum Number of Individuals) are most often employed. This presentation provides the preliminary results of an exhaustive study designed to determine the minimum number of individuals represented within a collection of 1,065 skeletal elements and fragments, belonging to the Eastern Washington University Anthropology Program. Results produced by established methods of computation were reinterpreted to account for the introduction of Procurement Bias in the calculation of MNI.
Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino
Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino
2023 Symposium
The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …
