German Cockroach Allergen Mitigation, Olivia Katz

Theses and Dissertations--Entomology

German cockroaches (Blatella germanica L.) remain one of the most challenging indoor pests to manage, due in large part to their cryptic nature, rapid reproduction, and resistance to insecticides. Because of their close proximity to humans, they also pose several serious health threats, including the production and dissemination of several potent allergens linked to asthma development and exacerbation. Given the risks associated with cockroach allergens, we examined the longevity of two distinct cockroach allergens (Bla g 1 and Bla g 5) in the home environment and the efficacy of cleaners at removing these allergens. Our findings show that Bla …

Unveiling The Bacterial Communities Of Aphaenogaster: Taxonomic Composition, Developmental And Species Influences, And The Impact Of Climate Change, Lily Kelleher

West Chester University Master’s Theses

Ants are vital keystone species in many ecosystems because they provide ecosystem services such as: seed dispersal, soil bioturbation, and pest control. However, ant bacterial symbioses remain largely unstudied, but these interactions are crucial because microbes play a vital role in the ants’ overall health. Today, global climate change is impacting our biodiversity, and we can use information about how changing temperatures impact the symbiotic bacterial communities associated with ants to predict future impact. Aphaenogaster rudis and A. fulva remain understudied in terms of their bacterial community and are important North American species. For this study, ants from several colonies …

Exploring The Reproductive Phenology Of Feral Horses In North America, Mattie Budine

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Feral horses (Equus ferus caballus) are a prolific species in western North America. Due to their life history traits and history of domestication, they have a longer foaling period compared to native ungulates, such as elk (Cervus canadensis) and mule deer (Odocoileus hemionus). I examined the observed foaling seasons of different regional herds throughout North America to identify if foaling seasons are uniform across latitudes or if they present a latitudinal shift similar to ungulates. My dataset (n=523 foals) consisted of various research studies and unpublished observations of different feral horse herds throughout North America. The results are graphs comparing …

Bridging Prairie Restoration And Regenerative Agriculture With Compost Tea / The Rocket Incident: Post-Fire Soil Microbe Recovery On The Eastern Washington University Restoration Site, April Hersey

EWU Masters Thesis Collection

Inland Pacific Northwest prairie is an endangered ecosystem that has been reduced by conversion to agriculture. There is growing interest in the role of soil microorganisms in prairie ecosystems, which may be crucial for restoration of the plant community through interspecies interactions within the rhizosphere. One method for improving soil microorganism community composition is compost tea: enriched liquid compost extract. Compost tea is used in regenerative agriculture to improve crop yields and protect against pathogens. While research has supported compost tea application in regenerative agriculture, it has not been widely studied in the context of ecosystem restoration. After beginning a …

A Hybrid Image Filtering Approach For Improving Edge Detection Of Riverbed Particles With Complex Textures, Po-Wei Lin, Hsun-Chuan Chan

Journal of Marine Science and Technology–Taiwan

The distribution of particle size in gravel-bed rivers affects the flow condition, sediment transport, and river morphology. However, conventional particle size analysis is laborious and time-consuming. To enhance the efficiency of particle size analysis, image-based methods have been widely explored, but complex particle textures increase the difficulty in identifying particle edges during image analysis. This study develops a filtering approach based on the rolling guidance filter and leverages the differences in grayscale gradients between particle edges and textures to design a guidance image tailored for the rolling guidance filter. This design enables the filter to preserve particle edges while smoothing …

The Effect Of Bait Types On Catch Performance In The Vietnamese Swimming Crab Trap Fishery, Nghiep K. Vu, Khanh Q. Nguyen, Luong T. Nguyen

Journal of Marine Science and Technology–Taiwan

Trapping is a primary fishing method to capture swimming crab species along the coast of Vietnam, because it has low ecological and environmental impacts. In trap fisheries, bait plays a primary role in determining the effectiveness of the gear and is one of the largest operational costs. Fishermen determine bait types based on their experience and what they can find, where trash fish caught by trawl fisheries is preferred and commonly used. However, the catch rates of swimming crab traps are typically low and highly variable and thus, there is considerable interest to improve the catchability. This study examined the …

Spatial Variation In Sexual Size Dimorphism And Mating Associations In The Color Polymorphic Eastern Red-Backed Salamander (Plethodon Cinereus), Maggie M. Hantak, Olivia L. Brooks, Kyle M. Brooks, Carl D. Anthony, Cari-Ann M. Hickerson, Kelly A. Williams, Shawn R. Kuchta

2025 Faculty Bibliography

Sexual selection due to mate preference for certain traits can maintain phenotypic diversity within populations and species. In taxa with discrete phenotypes, such as color polymorphic species, assortative mating may lead to disruptive selection and sympatric divergence, yet how such interactions vary over species' ranges remains poorly understood. To address this shortcoming, we examined spatial patterns of sexual size dimorphism and presumptive male–female mating pairs based on body size and coloration in the color polymorphic Eastern Red-backed Salamander, Plethodon cinereus. This species exhibits two common color morphs, striped and unstriped, that also differ in other elements of their biology, including …

Influence Of Multi-Species Data On Gene-Disease Associations In Substance Use Disorder Using Random Walk With Restart Models, Erich J. Baker, Everest U. Castaneda, Sharon Moore, Jason A. Bubier, Stephen K. Grady, Michael A. Langston, Elissa J. Chessler

Funded Scholarship

A major challenge lies in discovering, emphasizing, and characterizing human gene-disease and gene-gene associations. The limitations of data on the role of human gene products in substance use disorder (SUD) makes it challenging to transition from genetic associations to actionable insights. The integration of data from multiple diverse sources, including information-dense studies in model organisms, has the potential to address this gap. We demonstrate a modified performance of the Random Walk with Restart algorithm when multi-species data is integrated in the heterogeneous network within the context of SUD. Additionally, our approach distinguishes among disparate pathways derived from the Kyoto Encyclopedia …

Genetic Influences On Individual Variability In Western Lowland Gorilla (Gorilla Gorilla Gorilla) Social Behavior, Hadley Mueller-Hill

Master's Theses

While primates are considered highly social animals, the evolutionary origins and mechanisms underlying their social behaviors remain unclear. Not only do they exhibit an extensive range of behaviors, but individuals within the same species can also vary widely in their social interactions. Genetics play a significant role in shaping these individual variations in behavior; multiple genetic variants have been associated with differences in social behavior in mammals. Examples of these include MAOA and OXTR genes, which influence the expression of behaviors associated with antisocial and prosocial temperaments. Genetic polymorphisms affect primate interactions, impacting an individual’s ability to maintain its status …

Chironomids Shed Light On Organic Matter Dynamics In Macroinvertebrate Communities In Prairie Pothole Lakes In West-Central Minnesota, Usa, Tracey M. Anderson, Sarah G. Winikoff, Michael L. Sorensen, Melissa L. Rudeen

Biology Publications

The Prairie Pothole Region (PPR) in North America is characterized by a high density of wetlands that can range from temporary habitats to small lakes. Much of the PPR has been converted to agriculture resulting in outright habitat loss, eutrophication, sedimentation, introduction of agrochemicals, and the introduction of invasive plants and animals. We compared two prairie pothole lakes, Cottonwood Lake and Page Lake, to assess the functional roles and trophic structure of the macroinvertebrate communities in this highly altered landscape. We collected macroinvertebrate samples from littoral and profundal regions of each lake with an Ekman grab sampler in winters of …

Subsurface drainage is implemented throughout the Midwest United States to remove excess moisture from soil to enhance crop growth. Hydric soils are ubiquitous throughout Minnesota and are commonly drained due to their historically saturated conditions. Changing a soil's hydrology can impact its formation and properties. The alteration of physical, biological, and chemical soil properties can occur to both hydric and non-hydric soils, impacting overall soil health. The purpose of this study is to examine the short-term effects of tile drainage on the soil health of hydric and non-hydric soils in southern Minnesota. Research methods include: 1) collect soil-sediment cores to …

Elucidating The Non-Shivering Thermogenesis Response In The Black-Capped Chickadee (Poecile Atricapillus), Sweta Chand

Dissertations and Theses

The adaptation of small birds to cold environments involves mechanisms for both heat conservation and heat generation. While minimizing heat loss reduces the energy needed to maintain body temperature, thermogenesis remains essential. Shivering and non-shivering thermogenesis (NST) are two likely mechanisms supporting cold adaptation in small avian species. Although sarcolipin (SLN) aids NST in small mammals, studies in birds such as Dark- eyed Juncos have shown no increase or even a decrease in SLN expression during cold exposure, suggesting limited involvement. This may reflect biological differences or limitations of mRNA- focused sequencing, which excludes long non-coding RNAs (lncRNAs) capable of …

Montane regions in the Neotropics are hotspots of endemism and biodiversity, yet their species are especially vulnerable to the impacts of climate change and geographic isolation. This thesis investigates the evolutionary and ecological dynamics of three bird species endemic to the Darién Highlands of eastern Panama: Myadestes coloratus, Chlorospingus tacarcunae, and Margarornis bellulus. Through an integrative approach combining ecological niche modeling, morphometric analysis, and genomic data from ultraconserved elements (UCEs) and mitochondrial DNA, the study explores the historical biogeography, current distribution patterns, population structure, and phenotypic differentiation of these montane taxa. Ecological niche models revealed that suitable habitat …

Mctr3 Mitigates Cigarette Smoke-Induced Pulmonary Inflammation And Damage, Yu Par Aung Myo

Theses and Dissertations

Smoking is deleterious to our lungs and can precipitate in a multitude of diseases, including chronic obstructive pulmonary disease (COPD). COPD is primarily caused by smoking cigarettes and is a major public health issue. Current therapies only treat symptoms without halting or reversing disease progression, thus highlighting a large unmet need to develop new therapies. We address this gap by investigating maresin conjugate in tissue regeneration 3 (MCTR3) which is a newly discovered specialized pro-resoling mediator (SPM) that has the novel property of promoting tissue repair and regeneration in addition to being anti-inflammatory and pro-resolving. For the first time, we …

This study develops a Critical Environmental Communication (CEC) framework to assess the landscape of Environmental Communication research and to what extent and in which ways critical and justice-oriented perspectives are included. The CEC framework consists of four interconnected themes: (a) Marginalized Ecocultural Identities, (b) Context and Scale, (c) Power and Agency, and (d) Justice, Equity, Diversity, Access, and Inclusion (JEDAI). Using this framework in a bibliometric analysis examining 1,297 Environmental Communication publications, we assess the occurrence of these themes in the scholarship. Our analysis found that Marginalized Ecocultural Identities, and Context and Scale were most frequently occurring, while Power and …

Potentiation Of Gelonin Cytotoxicity By Pulsed Electric Fields, Olga N. Pakhomova, Eleni Zivla, Giedre Silkuniene, Mantas Silkunas, Andrei G. Pakhomov

Bioelectrics Publications

Gelonin is a ribosome-inactivating protein with extreme intracellular toxicity but poor permeation into cells. Targeted disruption of cell membranes to facilitate gelonin entry is explored for cancer and tissue ablation. We demonstrate a hundreds- to thousands-fold enhancement of gelonin cytotoxicity by pulsed electric fields in the T24, U-87, and CT26 cell lines. The effective gelonin concentration to kill 50% of cells (EC₅₀) after electroporation ranged from <1 nM to about 100 nM. For intact cells, the EC₅₀ was unattainable even at the highest gelonin concentration of 1000 nM, which reduced cell survival by only 5–15%. For isoeffective electroporation treatments using 300 ns, 9 µs, and 100 µs pulses, longer pulses were more efficient at lowering gelonin EC₅₀. Increasing the electric field strength of 8, 100 µs pulses from 0.65 to 1.25 kV/cm reduced gelonin EC₅₀ from 128 nM to 0.72 nM. Conversely, the presence of 100 nM gelonin enabled a more than 20-fold reduction in the number of pulses required for equivalent cell killing. Pulsed electric field-mediated delivery of gelonin shows promise for hyperplasia ablation at concentrations sufficiently low to minimize or avoid systemic toxicity.

Characterizing A Rad23 Dependent Ultraviolet Radiation Resistance In Tetrahymena Thermophila, Emma June Liimatta

Graduate Theses/Dissertations

In 2020, 10 million deaths were attributed to cancer, with multidrug resistance being responsible for over 90% of deaths in cancer patients receiving treatment. This study utilized the model organism Tetrahymena thermophila to study how cells become resistant to Ultraviolet Radiation (UV) radiation, a process similar to multidrug resistance, specifically focusing on the nucleotide excision repair and ubiquitin shuttle protein Rad23. The National Cancer Institute documented 30-60% of cancers tested had a mutation in RAD23. Knockdown of RAD23 in Tetrahymena thermophila demonstrated a UV resistance phenotype with decreased nucleotide excision repair and differential expression of proteins active within caspase-independent …
