Effectiveness Of Visual Representations In Undergraduate Human Anatomy And Physiology I & Ii, Mary Agnes Mestayer
Effectiveness Of Visual Representations In Undergraduate Human Anatomy And Physiology I & Ii, Mary Agnes Mestayer
Honors Theses
The objective of this project was to explore intersections between student preferences and student performance on anatomical visual representations in Human Anatomy and Physiology I and II. Visual representations are a critical resource for the formation of relationships between function and structure furthermore; students interpret these representations uniquely based on specific factors (learning objective, prior knowledge, the diagram studied, etc.). Phase I of this project gathered undergraduate responses to ten Likert-style questions on their opinions on diagrams and their use in the A&P classroom. Phase II of this project presented participants with twelve manipulated diagrams sourced from three diagram with …
Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi
Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi
Honors Theses
Unc13 are proteins in the presynaptic neurons essential in controlling synaptic vesicle fusion and synaptic transmission. Recently, the reduction of Drosophila melanogaster Unc13 proteins (Dunc13), were found to result in a resistance to alcohol, highly reminiscent of tolerance formation. I investigated whether genetically reducing Dunc13 activity in Drosophila brain regions leads to different forms of behavioral plasticity using an open field activity paradigm. In my approach, a Dunc13 RNAi transgene was expressed in the Drosophila brain within the mushroom body, the ellipsoid body, and in all neurons. The activities of the flies were examined in the open field paradigm to …
The Importance Of A Multidisciplinary Approach To Public Health: Addressing Food Insecurity Through A Biological And Sociological Lens, Chloe Grant
Honors Theses
Plants can sense the change of 1 oC in their growth environment and thus global climate change has a great impact on plant growth and development. The phenomenon that warm non-stress temperatures promote stem and petiole elongation, as well as leaf hyponastic growth, is collectively known as thermomorphogenesis. While it is known that the basic helix-loop-helix (bHLH) transcription factor PIF4 is highly inducible by temperature elevations and controls thermomorphogenesis in dicots (e.g., Arabidopsis thaliana), the molecular mechanism underlying thermomorphogenetic growth in monocots is not clear. In this study, I identify PIF4 orthologs in several economically important monocotyledonous species and …
Congenital Heart Defects And The Expression Of Ccdc141, Savanna Tillman
Congenital Heart Defects And The Expression Of Ccdc141, Savanna Tillman
Honors Theses
Congenital heart defects (CHDs) are one of the most prevalent types of birth defects in the United States. Both environmental and genetic components are known to contribute to the development of CHDs. One of the ways toxins present in the environment cause CHDs is by disrupting the expression of genes known to be vital in normal cardiac morphogenesis. Thus, the identification of both toxins that cause birth defects in cardiac development and genes expressed during heart development is crucial in order to fully understand the relationship between environment and genetics as they relate to CHD. Due to their external development, …
An Examination Of Mimetic Precision And The Selective Advantages Of Imprecise Mimics, Matt Hendricks
An Examination Of Mimetic Precision And The Selective Advantages Of Imprecise Mimics, Matt Hendricks
Honors Theses
First proposed by Henry Walter Bates in 1862, Batesian mimicry refers to the scenario in which an undefended species (the mimic) gains protection from predation due to its phenotypic resemblance to a noxious species (the model). Often, the model species possess a conspicuous phenotype which serves to warn predators of the species’ danger. A great deal of research spanning many decades has been devoted to this phenomenon as it applies to coral snakes. Coral snakes are quite noxious and are distinguished from other species of snakes by their banded patterns of bright colors such as red, yellow, and black. It …
The Role Of The Dal Neurons In Modulating Circadian Rhythms In Olfactory Short-Term Memory In Drosophila Melanogaster, Cooper Ruwe
The Role Of The Dal Neurons In Modulating Circadian Rhythms In Olfactory Short-Term Memory In Drosophila Melanogaster, Cooper Ruwe
Honors Theses
Depressed short-term memory (STM) abilities during non-adaptive times of the day can significantly impact those who work occupations that require peak levels of cognitive functioning around the clock. While much work has gone into understanding the endogenous clock and circadian rhythms, there is still much to learn about the neural circuity that underlies the daily rhythms that define these regular oscillations in STM performance. The DAL neurons in the Drosophila brain are part of the circadian network and innervate the mushroom bodies (MBs), the species’ olfactory learning center, making them compelling candidates to be involved in circadian circuitry for olfactory …
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, James Dubberly
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, James Dubberly
Honors Theses
The purpose of this baseline documentation is to conduct a report on our subject property and discuss the findings. A conservation easement is established by upholding a certain standard of a property’s current condition which makes a baseline documentation necessary for an easement to be enacted. Baseline documentation reports are used as a resource to monitor and enforce the legal agreements of the conservation easement. The subject property is currently owned by the Delta Wind Birds organization. In our scenario, this documentation report will serve to aid in the conversion of our subject property into a conservation easement in which …
Density Dependent Growth Of Pseudomonas Fluorescens In The Presence And Absence Of C. Elegans Predation In Liquid Media, Jack Landmann
Density Dependent Growth Of Pseudomonas Fluorescens In The Presence And Absence Of C. Elegans Predation In Liquid Media, Jack Landmann
Honors Theses
The purpose of this study was to understand the predator-prey relationship between C. elegans worms and P. fluorescens bacteria in liquid media. We were aiming to create a predation model of the relationship between these two species.
This study was performed through three experiments. Using 96-well plates, we were able to measure the change in optical density (OD) of these wells and calculate the growth rate. This growth rate was then graphed and analyzed. The first experiment contained P. fluorescens and KB liquid media, this study demonstrated that the bacterial population has a carrying capacity. We were also able to …

Microbial Community Responses To Salinification: Applications In Climate Change And Extreme Environments, Eric Weingarten
Microbial Community Responses To Salinification: Applications In Climate Change And Extreme Environments, Eric Weingarten
Electronic Theses and Dissertations
Sediment microbial community responses to elevated salinity are important in predicting the effects of sea level rise as well as in understanding those communities that can thrive in extreme environments. In this dissertation, I use natural and field experiments to investigate how salinity influences microbiome structure in coastal wetlands. Through the use of amplicon sequencing, I demonstrate that there are compositional differences between the microbiota of four wetland salinity classes: limnetic, oligohaline, mesohaline, and polyhaline. These results were reciprocated in a microcosm study exposing freshwater sediment to meso- and polyhaline conditions, showing that communities shifted proportionally to the magnitude of …
How Do Prey Capture And Simulated Fire Affect Growth And Nutrient Limitation In A Carnivorous Pitcher Plant, Sarracenia Alata?, Jalen Christopher Holloway
How Do Prey Capture And Simulated Fire Affect Growth And Nutrient Limitation In A Carnivorous Pitcher Plant, Sarracenia Alata?, Jalen Christopher Holloway
Electronic Theses and Dissertations
Carnivorous plants are defined as being able to benefit from the nutrients of prey in the environment, and have at least one trait that either retrieves, ingests, or lures a prey to its traps. The association of carnivorous plants with fire-prone habitats was initially described as a paradox, considering that carnivorous plants are often associated with nutrient-poor soils and fires can increase soil nutrient availability. This apparent paradox assumes, however, that the nutrients that increase in availability following fire are those also provided by prey, which might not be true. In habitats with nitrogen-poor soils, fire has been shown to …
