Identifying Grassland Cores In The Southeast: Relating Spatial Covariance To Avian Communities And Vegetation Structure, Lauren L. Berry
Identifying Grassland Cores In The Southeast: Relating Spatial Covariance To Avian Communities And Vegetation Structure, Lauren L. Berry
Graduate Theses and Dissertations
Globally, grasslands are declining in range, which is leading to a decline in grassland-dependent taxa. These declines can be attributed to a variety of issues, a major one being the encroachment of woody species into historic grasslands. There is a new framework for strategizing grassland management, referred to as “Defend the Core,” which calls for proactive management of intact grasslands, meaning conserving remaining grasslands by preventing woody encroachment in the first place. To successfully defend the core, it is imperative that we develop rapid methods to identify intact grassland cores for management priority. One method that can be used for …

Bilateral Asymmetry In The First Metacarpal: The Influence Of Handedness In Humans And Non-Human Primates, Lucyna A. Bowland
Graduate Theses and Dissertations
Muscle attachment sites (entheses) are often used to infer soft tissue anatomy and reconstruct behaviors within skeletal populations, but there remains a significant debate about whether and to what degree muscle use is accurately reflected in bony morphology. One of the most difficult problems in establishing the relationship between variation in muscle use and entheseal development is the inability to exclude a variety of external factors thought to influence enthesis development, including age, sex, body mass, and activity patterns. One way around this is to take advantage of the fact that humans are handed (preferentially using one hand over another, …

Investigate The Importance Of Local Magnetic Moment And Magnetic Interaction In Superconducting Fese Monolayer Using Density Functional Calculations, Sudip Pokharel
Graduate Theses and Dissertations
In this dissertation, we present two projects to study superconducting FeSe monolayer using first-principles density functional calculations. Monolayer FeSe/SrTiO3 system has very different properties as compared to its bulk counterpart in terms of critical superconducting temperature, Fermi surface topology and antiferromagnetic (AFM) stability. For FeSe monolayer, local magnetic moment (LMM) and AFM fluctuation are closely linked to superconductivity. However, LMM is not studied enough for FeSe monolayer. For FeSe/SrTiO3 system, the substrate SrTiO3 constrains the in-plane lattice constant for FeSe and also plays a crucial role in the onset and enhancement of superconductivity by providing charge transfer. …

The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
Graduate Theses and Dissertations
Behavioral plasticity, where individuals change their behaviors in response to varying environmental and social conditions, affects major evolutionary trajectories. But how individuals change these behaviors under certain social situations, and what the genetic causes and consequences of such behavioral changes are in response to social environments are yet to be fully understood. I address these questions in the context of anti-predatory behaviors (chapter 1), and mate choice (chapters 2, 3, 4) in tropical butterflies. In the context of anti-predatory behaviors, I found predator-specific behavioral changes in toxic Heliconius butterflies, suggesting variance in predation pressures and butterfly recognition of bird calls. …

Exploring The Effects Of N,N-Dimethylbiguanide And Ω-3 Pufas On Muscle Stem Cell Differentiation, Enayah Alhshim
Graduate Theses and Dissertations
The impacts of omega-3 (ω-3) fatty acid and metformin hydrochloride (Met-HCl) on muscle stem cells differentiation, mimicking the fetal muscle development under gestational diabetes mellitus (GDM), were investigated. ω-3 fatty acids have been known for their ability to regulate adipogenic transcription factors such as Sterol Regulatory Element-Binding Protien (SREBPs) and Peroxisome Proliferator-Activated Receptors (PPARs). This regulation resulted in gene expression modification for lipid metabolism and adipocyte differentiation, thus preventing excessive fat accumulation. Additionally, emerging evidence suggested that ω-3 fatty acids may also exert direct effects on myogenic processes that influence muscle stem cells proliferation, differentiation, and maturation. Meanwhile, Met-HCl, an …

Concerns around the economic and environmental consequences of suboptimal or excess dietary P levels in broiler diets has led to increased interest in determining ileal P digestibility values for feed ingredients. Therefore, two experiments (EXP) were conducted to determine the apparent (AID) and standardized ileal digestibility (SID) of P in various inorganic phosphates and meat and bone meals (MBM) using the direct method. In both EXP 1 and 2, ileal samples were collected at 22 d post-hatch from birds fed semi-purified diets based on dextrose and corn starch containing test ingredients and one N and P free (NPF) diet for …
The Role Of The Patterning Cascade Model In Human Mandibular Premolar Variation, Molly Militello
The Role Of The Patterning Cascade Model In Human Mandibular Premolar Variation, Molly Militello
Graduate Theses and Dissertations
Human mandibular premolars represent a morphologically transitional tooth class, possessing a relatively caniniform third premolar (P3) and a more molariform fourth premolar (P4). Marked variation in cusp height and lingual cusp number are characteristics unique to these postcanine teeth. The aim of this study is to determine if human premolar variation aligns with predictions outlined by the patterning cascade model (PCM). The PCM posits that tooth size and enamel knot spacing/surrounding inhibitory fields (approximated by cusp tip positioning) play a role in determining ultimate crown morphology, providing a predictive framework for examining crown variation within and between individuals. While there …
