A Preliminary Investigation Of The Interactions Between The Brood Parasite Chalcoela Iphitalis And Its Polistinewasp Hosts, Scott Nacko, Gregg Henderson

Faculty Publications

The life history of Chalcoela iphitalis-a common brood parasite of social wasps-has been described in previous literature, but critical information regarding oviposition behavior and possible differential host parasitism remain cryptic. Here we report on infestation levels of this moth in field populations of paper wasps in Polistes and Mischocyttarus, as well as the oviposition behavior of the moths under a laboratory setting. We found evidence for differential parasitism between paper wasp genera in the field, with almost 50% nest infestation in P. bellicosus and no occurrences of moth infestation in M. mexicanus. Laboratory results revealed that oviposition occurs only at …

Evolution Of Alu Subfamily Structure In The Saimiri Lineage Of New World Monkeys, Jasmine N. Baker, Jerilyn A. Walker, John A. Vanchiere, Kacie R. Phillippe, Corey P. St Romain, Paulina Gonzalez-Quiroga, Michael W. Denham, Jackson R. Mierl, Miriam K. Konkel, Mark A. Batzer

Faculty Publications

© The Author 2017. Squirrel monkeys, Saimiri, are commonly found in zoological parks and used in biomedical research. S. Boliviensis is the most common species for research; however, there is little information about genome evolution within this primate lineage. Here, we reconstruct the Alu element sequence amplification and evolution in the genus Saimiri at the time of divergence within the family Cebidae lineage. Alu elements are the most successful SINE (Short Interspersed Element) in primates. Here, we report 46 Saimiri lineage specific Alu subfamilies. Retrotransposition activity involved subfamilies related to AluS, AluTa10, and AluTa15. Many subfamilies are simultaneously active within …

© The Author 2017. Male dispersal from the natal group at or near maturity is a feature of most baboon (Papio) species. It potentially has profound effects upon population structure and evolutionary processes, but dispersal, especially for unusually long distances, is not readily documented by direct field observation. In this pilot study, we investigate the possibility of retrieving baboon population structure in yellow (Papio cynocephalus) and kinda (Papio kindae) baboons from the distribution of variation in a genome-wide set of 494 Alu insertion polymorphisms, made available via the recently completed Baboon Genome Analysis Consortium. Alu insertion variation in a mixed …

Phylogenomics Using Formalin-Fixed And 100+ Year-Old Intractable Natural History Specimens, Sara Ruane, Christopher C. Austin

Faculty Publications

© 2017 John Wiley & Sons Ltd Museum specimens provide a wealth of information to biologists, but obtaining genetic data from formalin-fixed and fluid-preserved specimens remains challenging. While DNA sequences have been recovered from such specimens, most approaches are time-consuming and produce low data quality and quantity. Here, we use a modified DNA extraction protocol combined with high-throughput sequencing to recover DNA from formalin-fixed and fluid-preserved snakes that were collected over a century ago and for which little or no modern genetic materials exist in public collections. We successfully extracted DNA and sequenced ultraconserved elements ((Formula presented.) = 2318 loci) …

Plant Genotype And Induced Defenses Affect The Productivity Of An Insect-Killing Obligate Viral Pathogen, Ikkei Shikano, Elizabeth M. Mccarthy, Bret D. Elderd, Kelli Hoover

Faculty Publications

© 2017 Elsevier Inc. Plant-mediated variations in the outcomes of host-pathogen interactions can strongly affect epizootics and the population dynamics of numerous species, including devastating agricultural pests such as the fall armyworm. Most studies of plant-mediated effects on insect pathogens focus on host mortality, but few have measured pathogen yield, which can affect whether or not an epizootic outbreak occurs. Insects challenged with baculoviruses on different plant species and parts can vary in levels of mortality and yield of infectious stages (occlusion bodies; OBs). We previously demonstrated that soybean genotypes and induced anti-herbivore defenses influence baculovirus infectivity. Here, we used …

Cannibalism And Infectious Disease: Friends Or Foes?, Benjamin G. Van Allen, Forrest P. Dillemuth, Andrew J. Flick, Matthew J. Faldyn, David R. Clark, Volker H.W. Rudolf, Bret D. Elderd

Faculty Publications

© 2017 by The University of Chicago. Cannibalism occurs in a majority of both carnivorous and noncarnivorous animal taxa from invertebrates to mammals. Similarly, infectious parasites are ubiquitous in nature. Thus, interactions between cannibalism and disease occur regularly. While some adaptive benefits of cannibalism are clear, the prevailing view is that the risk of parasite transmission due to cannibalism would increase disease spread and, thus, limit the evolutionary extent of cannibalism throughout the animal kingdom. In contrast, surprisingly little attention has been paid to the other half of the interaction between cannibalism and disease, that is, how cannibalism affects parasites. …

Hyalomma Koch, 1844 are ixodid ticks that infest mammals, birds and reptiles, to which 27 recognized species occur across the Afrotropical, Palearctic and Oriental regions. Despite their medical and veterinary importance, the evolutionary history of the group is enigmatic. To investigate various taxonomic hypotheses based on morphology, and also some of the mechanisms involved in the diversification of the genus, we sequenced and analysed data derived from two mtDNA fragments, three nuclear DNA genes and 47 morphological characters. Bayesian and Parsimony analyses based on the combined data (2242 characters for 84 taxa) provided maximum resolution and strongly supported the monophyly …

Genetic Dissection Of Seedling Stage Salinity Tolerance In Rice Using Introgression Lines Of A Salt Tolerant Landrace Nona Bokra, Venkata Ramana Rao Puram, John Ontoy, Steven Linscombe, Prasanta K. Subudhi

Faculty Publications

Salinity is an important abiotic stress affecting rice production worldwide. Development of salt tolerant varieties is the most feasible approach for improving rice productivity in salt affected soils. In rice, seedling stage salinity tolerance is crucial for better crop establishment. Quantitative trait loci (QTL) mapping using introgression lines (ILs) is useful for identification and simultaneous transfer of desirable alleles into elite genetic background. In the present study, 138 ILs derived from the cross between a high yielding elite salt susceptible japonica rice cultivar Jupiter and a salt tolerant indica landrace Nona Bokra were evaluated for salt tolerance at seedling stage …

Effect Of Metabolic Status On Conceptus–Maternal Interactions On Day 19 In Dairy Cattle: Ii. Effects On The Endometrial Transcriptome, Stefan Bauersachs, Constantine A. Simintiras, Roger G. Sturmey, Stefan Krebs, Jochen Bick, Helmut Blum, Eckhard Wolf, Pat Lonergan, Niamh Forde

Faculty Publications

The aim of this study was to test the hypothesis that the metabolic stresses associated with lactation alter the ability of the endometrium to respond appropriately to the conceptus by examining endometrial gene expression on day 19 of pregnancy. Immediately after calving, primiparous Holstein cows with similar production and fertility estimated breeding values were randomly divided into two groups and either dried off (i.e. never milked) immediately or milked twice daily. Approximately 65–75 days postpartum, grade 1 blastocysts recovered from superovulated Holstein heifer donors (n = 5) were transferred (1 per recipient) into lactating (n = 11) and nonlactating (n …

Reward Capacity Predicts Leptin Dynamics During Laboratory-Controlled Eating In Women As A Function Of Body Mass Index, Laura M. Holsen, Benita Jackson

Psychology: Faculty Publications

Objective—The role of leptin in mesolimbic signaling non-food-related reward has been well established at the pre-clinical level, yet studies in humans are lacking. The present investigation explored the association between hedonic capacity and leptin dynamics, and whether this association differed by BMI class.

Methods—In this cross-sectional study of 75 women (42 with lean BMIs, 33 with obese BMIs), we measured serum leptin before/after meal consumption. Reward capacity was assessed using the Snaith-Hamilton Pleasure Scale (SHAPS). Multiple regression tested whether reward capacity was associated with leptin AUC, with an interaction term to test differences between lean (LN) and obese …

Dietary Guidelines And Its Implications For Coconut Oil, Fabian M. Dayrit

Chemistry Faculty Publications

The dietary advice that is generally followed nationally and internationally closely follows the Dietary Guidelines for Americans which was first published in 1980 and which has been through eight editions. All of the editions of the Dietary Guidelines recommend a diet that is low in fat, and most editions recommend the replacement of saturated fat with polyunsaturated fat. This recommendation is based on the saturated fat-cholesterol-heart disease hypothesis that was first proposed by Ancel Keys in the 1950s. Coconut oil was labeled as unhealthy because of its high saturated fat composition. However, this label is unwarranted. Re-analysis of the work …

Synthesis And Evaluation Of Tetrahydroprotoberberines As Dopamine Receptor Ligands, Satishkumar V. Gadhiya

Dissertations, Theses, and Capstone Projects

Dopamine (DA) receptors belong to the G-protein coupled receptors (GPCRs) family, divided in to two groups based on their high homology transmembrane domains; D1-like DA receptors (D1, D5) and D2-like DA receptors (D2-D4). DA receptor specific ligands have been exploited as a means for studying the prognosis and curing several CNS disorders. Though several efforts have been devoted to discover selective and potent DA receptor ligands, complete selectivity within the DA receptor subtypes remains a challenge.

Tetrahydroprotoberberines (THPBs) are a group of naturally occurring tetracyclic alkaloids that belong to the tetrahydroisoquinoline family. A wide range of biological activities are associated …

The subject of this dissertation is to build an epistemic logic system that is able to show the spreading of knowledge and beliefs in a social network that contains multiple subgroups. Epistemic logic is the study of logical systems that express mathematical properties of knowledge and belief. In recent years, there have been increasing number of new epistemic logic systems that are focused on community properties such as knowledge and belief adoption among friends.

We are interested in revisable and actionable social knowledge/belief that leads to a large group action. Instead of centralized coordination, bottom-up approach is our focus. We …

Semantic Attention: Effects Of Modality, Lexicality And Semantic Content, David Britton

Dissertations, Theses, and Capstone Projects

Since the discovery of the Stroop Effect in 1935 questions about the role of language vs. non-lexical stimuli in selective attention remain. Early researchers attributed the powerful distracting influence shown in the Stroop task, naming the color in which a spelled word is printed when incongruent with the color name the word spells, to an automaticity of language that gives it privileged access to meaning, but many others since have shown various ways to reduce or even reverse this distracting effect of an incongruent word. This study addresses this by using EEG to record neural activity along with reaction time …

The Behavioral Effects Divorce Can Have On Children, Wanda M. Williams-Owens

Dissertations, Theses, and Capstone Projects

According to a statistical study (Cherlin et al. 1991) 40% of children who live in the United States will experience parental divorce before they reach the age of 18. Consequently, many children are affected by the process of divorce and its finalization. When my daughter was just nine years old, she asked incredulously why my husband and I were the only married couple in our neighborhood? After twenty-two years of marriage, I realized long-term marriages in my community are not conventional. When parents’ divorce, children often face the loss of one parent's constant presence and economic stability; as a result, …

The Racialization And Exploitation Of Foreign Workers By The Law, Seiko Ishikawa

Dissertations, Theses, and Capstone Projects

Intense demand for cheap labor in the United States has resulted in a widespread effect of employing high skilled immigrants in STEM fields. Examining how companies use high-skilled visa categories to create a flexible cheaper immigrant workforce, this paper demonstrates that skilled immigrants from Asia are being exploited through neutral skills-based criteria that are de facto racially biased. The purpose of this paper is to raise awareness of how, from the perspective of law and society, skills-based immigration works primarily to benefit the technological industry rather than skilled immigrants.

The Nucleus Accumbens Core Dopamine D1 And Glutamate Ampa/Nmda Receptors Play A Transient Role In The Performance Of Pavlovian Approach Behavior, Veronica Dobrovitsky

Dissertations, Theses, and Capstone Projects

The role of the nucleus accumbens core (NAc core) continues to be redefined with newly acquired data on neurochemical mechanisms mediating the learning and performance of behavior. Previous empirical data showed that dopamine transmission at the D1 receptor (D1R) plays a transient role in the expression of learned Pavlovian approach behavior. Here we show that, prior to overtraining, dopamine activity at D1Rs specifically within the NAc core is critical for the performance of approach behavior elicited by the recently-acquired reward-paired cue. Blockade of D1Rs in the NAc core, but not the dorsomedial striatum or NAc shell, disrupted approach responses during …

Activation And Habituation Of The Cingulate Cortex During Emotion Processing In Healthy Controls, Borderline, And Schizotypal Personality Disorder, Emily Balevich

Dissertations, Theses, and Capstone Projects

Disturbances in emotional functioning are central features of the clinical profiles of both borderline and schizotypal personality disorder (BPD and SPD, respectively). BPD is characterized by a high sensitivity to emotional stimuli and unusually strong and long-lasting reactions, indicative of impaired habituation to emotional stimuli (Linehan, 1993). Previous research suggests that SPD patients demonstrate limbic hyper-reactivity to unpleasant stimuli, at least initially, but intact habituation to repeated presentation of unpleasant stimuli (Hazlett et al., 2012). The cingulate cortex supports various aspects of emotion processing and regulation, and abnormalities of this region have been related to emotion dysfunction in SPD and …

Comparative Phylogeographic, Population Genomic, And Selection Inference With Development Of Hierarchical Co-Demographic Models, Alexander Xue

Dissertations, Theses, and Capstone Projects

Comparing demographic histories across assemblages of populations, species, and sister pairs has been a focus in phylogeography since its inception. Initial approaches utilized organelle genetic data and involved qualitative comparisons of genetic patterns for evaluating hypotheses of shared evolutionary responses to past environmental changes. This endeavor has progressed with coalescent model-based statistical techniques and advances in next-generation sequencing, yet there remains a need for methods that can analyze aggregated genomic-scale data from non-model organisms within a unified framework that considers individual taxon uncertainty and variance. To this end, the aggregate site frequency spectrum (aSFS), an expansion of the site frequency …

Reflections On The Implementation Of Improved Outcomes For Children And Its Impact On The Capacity Of Child Welfare Workers To Deliver Services, Rita Sanchez-Torres

Dissertations, Theses, and Capstone Projects

The emergence of the New Public Management with its emphasis on performance measurements and managerial strategies such as accountability, efficiency, and cost effectiveness have encouraged nonprofit child welfare agencies in New York City to pursue the practice of the private sector. In the current environment, service delivery has become more entrepreneurial, strategic and outcome minded on the assumption that the market-oriented approach is more effective (Watson-Bishop, 2007). This study examines the relationship between policy and service delivery. Specifically, it investigates the impact of the initiative known as Improved Outcomes for Children on child welfare supervisors in a managerial environment.

The Contributions Of Child And Romantic Attachment To Sleep Quality, Karen Estefane

Dissertations, Theses, and Capstone Projects

Little is known about the relation between attachment and sleep, although both develop around the first year of life and mutually influence each other. Furthermore, attachment styles and dimensions have been associated with sleep difficulties in both childhood and adulthood. However, these findings have not been consistent, especially among dismissing individuals. In addition, the specific contributions of both child and romantic attachment to sleep quality have not been investigated thus far. This cross-sectional study aims to examine the ways child and romantic attachment are associated with sleep quality. A sample of 671 heterosexual residents of the United States, aged 18 …

Bodies Of Resistance: On (Not) Naming Gender In The Medieval West, Alexander V. Baldassano

Dissertations, Theses, and Capstone Projects

This dissertation considers the genres of historiography, romance, hagiography, Chaucerian poetry, and court transcripts. While there are no extant manuscripts depicting transgender-like people’s accounts of themselves, literature of the Middle Ages is replete with fictionalized depictions of ambiguously or transgressively gendered individuals who are meant to symbolize or represent something other than themselves. By investigating how a variety of genres depicts sensationalized and transgressively gendered embodiments, I examine the presentation of transgender-like subjectivity as a manipulation of rhetoric. Viviane Namaste critiques theory such as Marjorie Garber’s Vested Interests, claiming that it reduces the transvestite figure to a rhetorical trope …
