Swim Bladder Morphology Changes With Female Reproductive State In The Mouth-Brooding African Cichlid Astatotilapia Burtoni, Julie M. Butler, Sarah M. Whitlow, Anwei P. Gwan, Prosanta Chakrabarty, Karen P. Maruska

Faculty Publications

© 2017. Published by The Company of Biologists Ltd. Journal of Experimental Biology. Mouth brooding is an extreme form of parental care in which the brooding parent carries the developing young in their buccal cavity for the duration of development. Brooding fish need to compensate for the brood weight on the anterior portion of their body. For fishes with a compartmentalized swim bladder, gas distribution between the chambers may aid in regulating buoyancy during brooding. To test this hypothesis, we took radiographs of Astatotilapia burtoni to compare the swim bladder morphology of gravid, mouth-brooding and recovering females. Following spawning, females …

Analyzing Young Readers' Empathetic Responses To A Mexican American Historical Narrative, Yvette Rivera

Theses and Dissertations

Empathy and cultural understanding of groups that are marginalized due to religious, ethnic or sexual background is essential for peace in schools, neighborhoods, and society at large. Literacy classrooms can be a safe environment in which students can develop their own understandings and empathies. Although worthwhile, much of the research lacks details of student reactions to the people and cultures read about in historical narratives, as well as a focus on pedagogical practices that could give students a deep understanding of the culture. This study analyzed the empathetic responses of 13 sixth grade students to themes presented in a Mexican …

Species Identification Of Vagrant Empidonax Flycatchers In Northeastern North America Via Non-Invasive Dna Sequencing, Nathan R. Goldberg, Nicholas A. Mason

Faculty Publications

Vagrant individuals from cryptic species complexes pose a persistent challenge for accurate species identification, hindering our understanding of vagrancy in these taxa. Here, we used non-invasive sampling of fecal matter to sequence the ND2 mitochondrial gene of 2 vagrant western flycatchers observed in northeastern North America. The DNAsequence data we recovered from these vagrants fell within a clade of known Empidonax difficillis (Pacific-slope Flycatcher) haplotypes. Our work provides robust records of 2 vagrant Pacific-slope Flycatchers in the northeastern US. These findings illustrate the power of non-invasive sampling for species identification of vagrants from cryptic species complexes.

Incorporating Flaxseed (Linum Usitatissimum) Oil Into Queso Blanco At Different Stages Of The Cheese Manufacturing Process, Cristhiam Gurdian, Vondel Reyes, Emmanuel Kyereh, Franklin Bonilla, Cesar Galindo, Alexander Chouljenko, Kevin Mis Solval, Charles Boeneke, Joan M. King, Subramaniam Sathivel

Faculty Publications

The objective of this study was to evaluate the physicochemical and microbial properties of queso blanco (QB) with flaxseed oil (FO) incorporated at different stages of the cheese manufacturing process. Whole milk was homogenized, coagulated with citric acid, salted with NaCl, and the resulting curds were pressed. Then QBFO was produced by incorporating FO during homogenization (QBFO-H), coagulation (QBFO-C), or salting (QBFO-S). The cheeses were stored at 8 °C for 30 days. Significantly lower lipid oxidation in QB was observed when FO was added during coagulation or salting compared to homogenization. However, lipid oxidation values of QBFO-H did not exceed …

Comparison Of Five Methods For Parameter Estimation Under Taylor's Power Law, Peijian Shi, David A. Ratkowsky, Ningtao Wang, Yang Li, Lei Zhao, Gadi V.P. Reddy, Bai Lian Li

Faculty Publications

Taylor's power law (TPL) can be applied to the mean-variance relationship for various quantities, e.g., population densities over space and time, biomass of plants in the growth processes, developmental rates and growth rates of arthropods at different temperatures, etc. When TPL holds in the grouped data (e.g., the biomass of plants at different investigation times with limited replicates at each investigation), we must consider the heterocedasticity when carrying out the parameter estimation for a given mathematical model. We propose two new target functions based on TPL and attempt to more accurately estimate the model parameter(s). By capturing the mean-variance relationship, …

Challenges In Development Of Sperm Repositories For Biomedical Fishes: Quality Control In Small-Bodied Species, Leticia Torres, Yue Liu, Amy Guitreau, Huiping Yang, Terrence R. Tiersch

Faculty Publications

Quality control (QC) is essential for reproducible and efficient functioning of germplasm repositories. However, many biomedical fish models present significant QC challenges due to small body sizes (<5 >cm) and miniscule sperm volumes (<5 >μL). Using minimal volumes of sperm, we used Zebrafish to evaluate common QC endpoints as surrogates for fertilization success along sequential steps of cryopreservation. First, concentrations of calibration bead suspensions were evaluated with a Makler® counting chamber by using different sample volumes and mixing methods. For sperm analysis, samples were initially diluted at a 1:30 ratio with Hanks' balanced salt solution (HBSS). Motility was evaluated by …

Effect Of Lactation On Conceptus-Maternal Interactions At The Initiation Of Implantation In Cattle: I. Effects On The Conceptus Transcriptome And Amino Acid Composition Of The Uterine Luminal Fluid, Niamh Forde, Constantine A. Simintiras, Roger G. Sturmey, Alexander Graf, Eckhard Wolf, Helmut Blum, Pat Lonergan

Faculty Publications

Approximately 65-75 days postpartum (dpp), the estrous cycles of nonlactating (dried off immediately postpartum: n = 12) and lactating (n = 13) Holstein Friesian cows were synchronized and on day 7 a single blastocyst derived from superovulated nulliparous Holstein Friesian heifers was transferred to each cow. A control group of nulliparous heifers (n = 8) were synchronized, inseminated to a standing heat, and slaughtered on the same day as nonlactating and lactating recipients (day 19; estrus = day 0). The uterine horn ipsilateral to the corpus luteum was flushed with 10 ml phosphate-buffered saline and the conceptus, and uterine luminal …

Effects Of Isolation On Ant Assemblages Depend On Microhabitat, Xuan Chen, Benjamin Adams, Michael Layne, Christopher Swarzenski, David Norris, Linda Hooper-Bui

Faculty Publications

How isolation affects biological communities is a fundamental question in ecology and conservation biology. Local diversity (α) agnd regional diversity (γ) are consistently lower in insular areas. The pattern of species turnover (β diversity) and the influence of isolation on competitive interactions are less predictable. Differences in communities across microhabitats within an isolated patch could contribute to the variability in patterns related to isolation. Trees form characteristically dense and sparse patches (low vs. high isolation) in floating marshes in coastal Louisiana, and canopy and root areas around these trees could support distinct ant communities. Consequently, trees in floating marshes provide …

Architectural Representation And The Dragon’S Lair In Beowulf, Margaret Heeschen

Masters Theses

Since the early twentieth century, the dragon’s lair of Beowulf has been primarily associated with the early megalithic mounds of northern Europe. This interpretation of the space, however, does not account for the many contradictions present in the poet’s descriptions. In order to fully understand the quiddity of the dragon’s lair, we must resolve three major issues with previous interpretations: the use of rare words with unclear meanings, contradictions in descriptions of the physical space, and an assumption by scholars that the poet is describing a single type of space identifiable in the historical record. By addressing each of these …

Apan Production Through Photooxidation Of Isoprene In The Presence Of NoX, Timothy Glidewell

Masters Theses

Peroxyacyl nitrates (PANs, RC(O)OONO₂) are of great importance in atmospheric chemistry. They act as transporters of reactive nitrogen, and radical delivery agents. There are no known natural emission sources of PANs; they are produced through reaction of volatile organic compounds (VOCs) and nitrogen oxides (NO_x) in the atmosphere.

VOCs can enter the atmosphere through biogenic and anthropogenic pathways. It has been estimated that isoprene makes up 70% of the biogenic VOCs (BVOCs) emitted annually. Isoprene has been shown to impact ozone levels in both rural and urban areas by sequestering and transporting NO_x in the form …

Buspirone Maintenance Does Not Alter The Reinforcing, Subjective, And Cardiovascular Effects Of Intranasal Methamphetamine, Anna R. Reynolds, Justin Charles Strickland, William W. Stoops, Joshua A. Lile, Craig R. Rush

Pharmaceutical Sciences Faculty Publications

Background—Medications development efforts for methamphetamine-use disorder have targeted central monoamines because these systems are directly involved in the effects of methamphetamine. Buspirone is a dopamine autoreceptor and D3 receptor antagonist and partial agonist at serotonin 1A receptors, making it a logical candidate medication for methamphetamine-use disorder. Buspirone effects on abuse-related behaviors of methamphetamine have been mixed in clinical and preclinical studies. Experimental research using maintenance dosing, which models therapeutic use, is limited. This study evaluated the influence of buspirone maintenance on the reinforcing effects of methamphetamine using a self-administration procedure, which has predictive validity for clinical efficacy. The impact …

December 2017 marked 50 years since archaeologist Michael J. O’Kelly first observed the solar illumination of the burial chamber in the Neolithic passage tomb at Newgrange during the period of the winter solstice. O’Kelly subsequently recorded direct sunlight entering Newgrange through the ‘especially contrived slit which lies under the roof-box at the outer end of the passage roof’ on 21 December 1969. The discovery of this historic phenomenon, dating back over 5,000 years, captured the public interest and imagination at that time and ever since. In this major article published in the Winter 2017 edition of Archaeology Ireland (date of …

Plekhg5-Regulated Autophagy Of Synaptic Vesicles Reveals A Pathogenic Mechanism In Motoneuron Disease., Patrick Lüningschrör, Beyenech Binotti, Benjamin Dombert, Peter Heimann, Angel Perez-Lara, Carsten Slotta, Nadine Thau-Habermann, Cora R. Von Collenberg, Franziska Karl, Markus Damme, Arie Horowitz, Isabelle Maystadt, Annette Füchtbauer, Ernst-Martin Füchtbauer, Sibylle Jablonka, Robert Blum, Nurcan Üçeyler, Susanne Petri, Barbara Kaltschmidt, Reinhard Jahn, Christian Kaltschmidt, Michael Sendtner

Department of Medicine Faculty Papers

Autophagy-mediated degradation of synaptic components maintains synaptic homeostasis but also constitutes a mechanism of neurodegeneration. It is unclear how autophagy of synaptic vesicles and components of presynaptic active zones is regulated. Here, we show that Pleckstrin homology containing family member 5 (Plekhg5) modulates autophagy of synaptic vesicles in axon terminals of motoneurons via its function as a guanine exchange factor for Rab26, a small GTPase that specifically directs synaptic vesicles to preautophagosomal structures. Plekhg5 gene inactivation in mice results in a late-onset motoneuron disease, characterized by degeneration of axon terminals. Plekhg5-depleted cultured motoneurons show defective axon growth and impaired autophagy …

"Hear Us, See Us": Constructing Citizenship In The Margins, Tricia M. Hagen Gray

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

The meatpacking industry has drawn an increasing number of immigrants to the Midwestern community of Washington River from Mexico and Central America, making it a New Latino Diaspora (NLD) receiving community. Demographic change amidst the sociopolitical landscape of neoliberalism, declining civic engagement, and polarized partisan politics has forced interaction between longstanding residents and newcomers who are socially, culturally, and linguistically different. Historically marginalized groups have sought to claim rights—especially since Donald Trump’s election in 2016—resulting in a deeper fissure of the social landscape.

Washington River High School provided a context in which to explore questions about how students construct citizen …

Colorful Seashells: Identification Of Haem Pathway Genes Associated With The Synthesis Of Porphyrin Shell Color In Marine Snails, Suzanne T. Williams, Anne E. Lockyer, Patricia Dyal, Tomoyuki Nakano, Celia K. C. Churchill, Daniel Isaac Speiser

Faculty Publications

Very little is known about the evolution of molluskan shell pigments, although Mollusca is a highly diverse, species rich, and ecologically important group of animals comprised of many brightly colored taxa. The marine snail genus Clanculus was chosen as an exceptional model for studying the evolution of shell color, first, because in Clanculus margaritarius and Clanculus pharaonius both shell and foot share similar colors and patterns; and second, because recent studies have identified the pigments, trochopuniceus (pink-red), and trochoxouthos (yellow-brown), both comprised of uroporphyrin I and uroporphyrin III, in both shell and colored foot tissue of these species. These unusual …

Relative Importance Of Different Body Channels To The Believability Of A Stylized 3d Character Animation In A Full Body Shot, Saikiran Anasingaraju

Open Access Theses

Character animation involves movement in different channels of the character’s body. There is a norm in the animation industry that each of these different body channels has varying contributions to the believability of an acting performance: body movement being the highest contributor and lip sync the lowest. This thesis investigated this norm using statistical analysis. While the reduction of body motion caused the biggest drop in believability, similar reductions in facial animation and lip sync have not made a significant effect on the believability. The only exception to the above statement is the animation depicting the emotion sadness, where no …

Interactivity Factors In Visualization-Based Exploratory Search, Ali Baigelenov

Open Access Theses

Two of the main components of visualizations are representation and interaction. Several researchers have noted that the interaction component has been receiving less attention than the visual (representation) component. It was also noted by several researchers that there is currently no well-developed theoretical base for interaction research in information visualization. A number of important contributions to this problem were made, resulting in different frameworks that aimed to deal with various aspects of interaction design, such as benefits, costs, and techniques, to name a few. Despite the contributions and findings, the interactivity factors of diversity, complementarity, and fitness are still relatively …

Effects Of Dry-Aging On Eating Quality, Physicochemical, And Microbiological Attributes Of Grass-Fed Beef Loins, Jordy Berger

Open Access Theses

The United States has the greatest number of cattle on feed and is the largest producer of beef in the world (Jones, 2017). As a major contributor to the American economy, it is vital for the beef industry to provide consumers with high quality products that meet their expectations in order to ensure continued meat purchase (Schroeder and Mark, 2000). To accomplish these objectives, an understanding of beef eating quality attributes and ongoing research to identify how and what factors contribute to these attributes is essential. Beef palatability is assessed by the evaluation of tenderness, juiciness, and flavor (Reicks et …
