Biology: Faculty Publications and Other Works

Purpose Obesity is linked to cognitive dysfunction in humans and rodents, and its effects can be passed on to the next generation. However, the extent of these effects is not well understood. The purpose of this study was to determine the effect of a prenatal maternal high-fat diet and an individual high-fat diet in inbred mice. Methods We varied maternal diet and offspring diet to test the hypothesis that a high-fat diet would increase anxiety, reduce activity levels, and impair nest-building. First, we fed a high-fat (HF) or low-fat (LF) diet to genetically identical female Small (SM/J) mice and mated …

Detecting Significant Genotype–Phenotype Association Rules In Bipolar Disorder: Market Research Meets Complex Genetics, René Breuer, Manuel Mattheisen, Josef Frank, Bertram Krumm, Ney Alliey Rodriguez

School of Medicine Publications

Background: Disentangling the etiology of common, complex diseases is a major challenge in genetic research. For bipolar disorder (BD), several genome-wide association studies (GWAS) have been performed. Similar to other complex disorders, major breakthroughs in explaining the high heritability of BD through GWAS have remained elusive. To overcome this dilemma, genetic research into BD, has embraced a variety of strategies such as the formation of large consortia to increase sample size and sequencing approaches. Here we advocate a complementary approach making use of already existing GWAS data: a novel data mining procedure to identify yet undetected genotype–phenotype relationships. We adapted …

Assessing The Ecological Implications Of The Altered Flow And Sediment Regimes Of The Rio Grande Along The West Texas-Mexico Border, Demitra E. Blythe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large, exotic (those whose headwaters are in distant places) rivers are some of the most unique and diverse ecosystems on earth. Because they often flow through a multitude of biomes and climates, their waters are a vital resource not only for the organisms that inhabit these rivers, but for human societies as well. Thus, large rivers, like the Rio Grande, that flow through arid and agricultural regions are highly regulated and diverted. Regulation and dewatering upset a river’s natural flow regime (e.g., magnitude, duration, timing of large flood events), subsequently impacting the river’s ability to transport its sediment supply, and …

The Nesting Ecology Of Woodpeckers In The Eastern Cascades And Their Interactions With Nest Competitors And Predators, Samuel D. Cowell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Woodpeckers create nesting cavities for other birds and animals in forests. This creates dynamic interactions between both woodpeckers and these other animals. Using video cameras, we documented direct behavioral interactions between nesting woodpeckers and other animals in the Eastern Washington Cascades during the 2015 and 2016 breeding seasons. Additionally, we offered 937 students in a General Biology laboratory course to participate in this original research opportunity and described and the impact the experience had on the participants as well as the researchers.

In 2015, Western Blubebirds took over two active Black-backed Woodpecker nests by physically attacking the woodpeckers. In 2016, …

Identifying Criticality In Market Sentiment: A Data Mining Approach, Vaibhav Sahu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The aim of this thesis is to study and identify time periods of high activity in commodity and stock market sentiment based on a data mining approach. The method is to develop tools to extract relevant information from web searches and Twitter feeds based on the tally of certain keywords and their combinations at regular intervals. Periods of high activity are identified by a measure of complexity developed for analysis of living systems. Experiments were conducted to see if the measure of activity could be applied as a predictor of changes in stock market and commodity prices.

Blue And Red Light Effects On Stomatal Oscillations, Trevor R. Ballard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants absorb CO₂ through pores in their leaves called stomata, which are known to open and close in response to myriad environmental and physiological triggers. We demonstrate that blue light inhibits stomatal aperture oscillations in both the guard cells and surrounding tissue layers, whereas these oscillations continue under the influence of red light. This observation of blue light behavior agrees with recent research and suggests another physiological pathway for oscillations.

Compassion Fatigue Among Mental Healthcare Providers And The Impact On Overall Wellbeing, Ruchi Patel

Doctoral Dissertations

The impact of burnout, secondary stress and compassion fatigue on a mental healthcare provider’s work and personal life has been increasingly studied due to negative ramifications on our community healers. The present study used a cross-sectional design to survey mental healthcare providers across specialty and discipline in efforts to gain a better understanding of the relationship between a provider’s degree of compassion fatigue and specific demographic variables, physical health and their spirituality. One hundred and thirty-seven participants across the …

Genomics And Development Of Lentinus Tigrinus: A White-Rot Wood-Decaying Mushroom With Dimorphic Fruiting Bodies, Baojun Wu, Zhangyi Xu, Alicia Knudson, Alexis Carlson, Naiyao Chen, Sam Kovaka, Kurt Labutti, Anna Lipzen, Christa Pennachio, Robert Riley, Wendy Schakwitz, Kiwamu Umezawa, Robin A. Ohm, Igor V. Grigoriev, Laszlo G. Nagy, John Gibbons, David Hibbett

Biology

Lentinus tigrinus is a species of wood-decaying fungi (Polyporales) that has an agaricoid form (a gilled mushroom) and a secotioid form (puffball-like, with enclosed spore-bearing structures). Previous studies suggested that the secotioid form is conferred by a recessive allele of a single locus. We sequenced the genomes of one agaricoid (Aga) strain and one secotioid (Sec) strain (39.53–39.88 Mb, with 15,581–15,380 genes, respectively). We mated the Sec and Aga monokaryons, geno-typed the progeny, and performed bulked segregant analysis (BSA). We also fruited three Sec/Sec and three Aga/Aga dikaryons, and sampled transcriptomes at four developmental stages. Using BSA, we identified 105 …

Effects Of Exercise On Clinical Couple Interactions, Samantha Karma-Jean Simpson

Theses and Dissertations

Research has shown that exercise has the potential to improve couple relationships. This study contributes to current literature by examining the associations between exercise, its duration, and its intensity and daily clinical couple interactions. Participants were 22 married couples in a treatment-as-usual setting who completed daily diaries about daily behaviors and marital interactions. Multilevel models were run, and results showed that wives who exercised were more likely to report a negative interaction with their husband that day. When wives exercised longer, both they and their husbands were more likely to report positive interactions that day. Interestingly, if husbands exercised longer …

High Phenolic Content Fails To Deter Mesograzer Consumption Of Myriophyllum Spicatum (Eurasian Watermilfoil) In New England, Latina Steele, Courtney Ray, Michele Guidone

Biology Faculty Publications

Eurasian watermilfoil (Myriophyllum spicatum) is often considered one of the most aggressive macrophyte invaders in freshwater habitats throughout the United States. However, conditions leading to successful milfoil invasions are not well understood. This study sought to illuminate the role of 4 herbivores in determining milfoil invasion success via either enemy release or biotic resistance. We determined feeding preferences of three herbivores native to the northeastern United States and measured milfoil phenolic content, which may act as an herbivore feeding deterrent. We found that phenolic content in milfoil was two times higher than in two of the most abundant native macrophytes …

The present study sought to examine the relation between such co‐occurring symptoms and social challenges. Parents of adolescents with autism (N = 113) reported upon social challenges via the social responsiveness scale (SRS) and anxiety and ADHD symptomatology via the Child Behavior Checklist. Results revealed differences in SRS scores across co‐occurring symptom subgroups (Anxiety, ADHD, Both, Neither)—namely, adolescents with autism and anxiety as well as those with autism, anxiety, and ADHD showed greater scores on the SRS than …

Analysis Of Synthetic Opioids In Postmortem Blood, Vitreous Humor, And Brain Tissue, Rachel K. Chesser

Student Theses

In the United States, the use of new synthetic opioids (e.g. fentanyl and derivatives) has become an increasing health issue with thousands of overdose deaths being observed since 2013. With the high mortality rate associated with these substances, postmortem analyses and interpretation of synthetic opioids has become extremely important. However, due to the novelty of these compounds, the available data is limited and provides challenges to toxicologists. The focus of this project was to examine the postmortem distribution of new synthetic opioids in blood, vitreous humor, and brain tissue. New methods were developed and validated to quantify 13 synthetic opioids …

This exploratory article reflects on the teaching experiences for a course on “Entrepreneurial Leadership in Ethnic Chinese Business” at the Singapore Management University (SMU). It was categorised as a mobile learning course with reference to the flipped classroom model, learner mobility, and user-generated content outside the classroom. We examine three examples of mobile learning projects which were assigned to students so that they would be able to internalise key course objectives such as gaining an appreciation of the structure, functions, and cultural uniqueness of traditional small Chinese business organisations in Singapore. The paper also addresses some of the challenges faced …

Budget-Constrained Regression Model Selection Using Mixed Integer Nonlinear Programming, Jingying Zhang

Graduate Theses and Dissertations

Regression analysis fits predictive models to data on a response variable and corresponding values for a set of explanatory variables. Often data on the explanatory variables come at a cost from commercial databases, so the available budget may limit which ones are used in the final model.

In this dissertation, two budget-constrained regression models are proposed for continuous and categorical variables respectively using Mixed Integer Nonlinear Programming (MINLP) to choose the explanatory variables to be included in solutions. First, we propose a budget-constrained linear regression model for continuous response variables. Properties such as solvability and global optimality of the proposed …

Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan

Graduate Theses and Dissertations

The USDA Forest Service aims to use satellite imagery for monitoring and predicting changes in forest conditions over time within the country. We specifically focus on a 230, 400 hectares region in north-central Wisconsin between 2003 - 2012. The auxiliary data collected from the satellite imagery of this region are relatively dense in space and time and can be used to efficiently predict how the forest condition changed over that decade. However, these records have a significant proportion of missing values due to weather conditions and system failures. To fill in these missing values, we build spaciotemporal models based on …

The Persistence Of The Past Into The Future: Indigenous Futurism And Future Slave Narratives As Transformative Resistance In Nnedi Okorafor's The Book Of Phoenix, Ellen Eubanks

Graduate Theses and Dissertations

In recent years, a number of authors have written science fiction works that express the concerns and experiences of marginalized people groups, including those in postcolonial societies, Indigenous/First Nations peoples, and other racial minorities. These works provide counter narratives to that of much canonical science fiction, which developed from narrative forms that often explicitly and implicitly supported colonial ideologies, and still often includes these ideologies today. This thesis analyzes the way The Book of Phoenix (2015) by the NigerianAmerican speculative fiction author Nnedi Okorafor uses a combination of the forms of Indigenous futurism and what Isiah Lavender terms meta-slavery narratives …

The Intergenerational Transmission Of Parental Practices That Influence The Educational Outcome Of Latinxs In The United States, Ana E. Kemple Reeves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parental involvement practices in education have traditionally referred to overt forms of involvement such as attending school meetings, parent teacher conferences, and volunteering at the school. Research suggests that Latinx parents do not utilize these approaches as much as they do subtler practices. These practices are manifested in parents’ communication with their children, their parenting styles, and the academic expectations they place on their children. The current study intended to recognize the parental practices used by Latinx parents that contribute to educational attainment and combat fixed beliefs regarding their lack of involvement in their children’s education. The data collection was …

Carbon Monoxide On Demand: Light-Induced Co Release Of Flavonols, Stacey N. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carbon monoxide (CO) is an extremely useful molecule with applications in industrial manufacturing, synthetic procedures as a C1 building block, and as a potential pharmaceutical to produce anti-inflammatory effects and vasodilation. However, the toxicity associated with CO has prevented its full utilization. In order to safely handle CO, compounds and molecules have been developed that act as storage materials for the gas. Ideal storage platforms only release CO upon stimulation via a trigger. Light activation is the most desirable trigger as it can be regulated in terms of the intensity and the wavelength of light used. The majority of light-induced …

Population Structure Of A Global Agricultural Invasive Pest, Bactrocera Dorsalis (Diptera: Tephritidae), Yu Jia Qin, Matthew N. Krosch, Mark K. Schutze, Yue Zhang, Xiao Xue Wang, Chandra S. Prabhakar, Agus Susanto, Alvin K.W. Hee, Sunday Ekesi, Kemo Badji, Mahfuza Khan, Jia Jiao Wu, Qiao Ling Wang, Ge Yan, Li Huan Zhu, Zi Hua Zhao, Li Jun Liu, Anthony R. Clarke, Zhi Hong Li

All Peer-Reviewed Publications

Bactrocera dorsalis, the Oriental fruit fly, is one of the world's most destructive agricultural insect pests and a major impediment to international fresh commodity trade. The genetic structuring of the species across its entire geographic range has never been undertaken, because under a former taxonomy B. dorsalis was divided into four distinct taxonomic entities, each with their own, largely non-overlapping, distributions. Based on the extensive sampling of six a priori groups from 63 locations, genetic and geometric morphometric datasets were generated to detect macrogeographic population structure, and to determine prior and current invasion pathways of this species. Weak population structure …

Consequences Of Shade Management On The Taxonomic Patterns And Functional Diversity Of Termites (Blattodea: Termitidae) In Cocoa Agroforestry Systems, Ambele C. Felicitas, Bisseleua D.B. Hervé, Sunday Ekesi, Komivi S. Akutse, Christian T.C.L. Djuideu, Marie J. Meupia, Olubukola O. Babalola

Termites have gained importance as major pests in cocoa agroforests. Proper identification of termite species and knowledge on their functional diversity are the first steps in developing environmentally compatible management strategies. We tested the hypothesis that patterns of termite species richness in different cocoa agroforests is related to responses by termite functional groups to changes in shade management. We compared termite assemblages under five cocoa agroforestry systems in Cameroon to assess the impact of shade on termite taxonomic and functional group diversity. Sampling was done using a modified standardized transect method. Two 30 × 30 m quadrates each divided into …

We conclude the manuscript with a comprehensive research agenda providing future priorities towards sustainable control of this important tomato pest.

Prospects Of Endophytic Fungal Entomopathogens As Biocontrol And Plant Growth Promoting Agents: An Insight On How Artificial Inoculation Methods Affect Endophytic Colonization Of Host Plants, Bamisope Steve Bamisile, Chandra Kanta Dash, Komivi Senyo Akutse, Ravindran Keppanan, Oluwatoyin Grace Afolabi, Mubasher Hussain, Muhammad Qasim, Liande Wang

All Peer-Reviewed Publications

Entomopathogenic fungi (EPF) can be established as endophytes in the host plants to offer a long-term preventive measure for pests and diseases. This practice serves as a better alternative to the common practice of periodic direct application of EPF on plants or the target pests as a short-term defense strategy against pests and diseases. These fungal endophytes, aside from their role in pests and diseases prevention, also act as plant growth promoters. Several fungal endophytes have been associated with improvement in plant height, dry and wet weight and other growth parameters. However, many limiting factors have been identified as mitigating …
