Interactive Effects of Warming and Nitrogen Availability on Soil Carbon Fluxes: Implications for a Changing Climate
(2024-05-23) Waldron, Emma; Hoopes, Martha
The excess of greenhouse gasses like carbon dioxide in the atmosphere urgently calls for a deeper understanding of existing natural mechanisms for carbon sequestration. Soils act as a critical natural carbon sink, storing at least twice as much carbon as there is globally in the atmosphere and in plant biomass combined. However, climate change and associated increases in average temperatures can impact soil carbon storage processes, converting carbon sinks to carbon sources. The response of soil carbon to warming is complex and depends on many environmental factors. This study focuses on nitrogen (N) availability, which may mediate the effects of warming on soil carbon via its influence on microbial activity and decomposition. Strong support for this hypothesis is lacking, however, as these variables are difficult to isolate in the field. In this greenhouse experiment, I cross two warming treatments with four N treatments in order to disentangle some of these relationships. To get a picture of how carbon fluxes responded to my treatments, I measured soil organic matter (SOM) as a proxy for the amount of carbon stored in the soil, and soil respiration rate to see how much carbon the soil was releasing. I also measured nitrate and ammonium levels as well as nitrification and mineralization rates in the soil to get a fuller understanding of how my treatments actually affected both N availability and the soil microbial activity governing N availability. I found significant effects from both my warming treatments and my nitrogen treatments, along with significant interactions between the two. Because my pots had living microbes and plants, there were feedbacks between N and C above and belowground, creating complicated relationships between warming, N, SOM, and soil respiration (as expected). Further clarification of these dynamics will be critical for making accurate climate predictions and for strategically targeting restoration efforts to mitigate climate change.

Finding the clitoris: using comparative anatomical methods to describe and characterize the clitorises of alpacas (Vicugna pacos)
(2024-05-21) Thompson, Grace; Brennan, Patricia; Lijek, Rebeccah; Diewald, Barbie
The clitoris, like many female reproductive organs, is a vastly understudied organ with a long history of misunderstanding. Despite poor representation in scientific literature, the clitoris plays an important role in pleasure, behavior, and reproduction among vertebrate animals. Clitoral stimulation has been linked to induced ovulation and increased rates of fertilization in domesticated agricultural animals. Alpaca (Vicugna pacos) clitoris anatomy has not been previously described despite the prevalence of alpaca farms across the world. Alpacas have unusually long copulation for an Artiodactyl (over 20 minutes on average), and a novel pattern of deep intromission with the penis causing abrasion and hematoma of the female mucosal layer along the upper reproductive tract and uterine horns. Through methods of dissection, histology, CT segmentation, and in vivo observation, we found that alpacas have a well-developed clitoris consisting of the primary components of corpus cavernosum, vestibular bulbs, extensive vascularization and innervation, and clitoral muscles. In addition to these expected structures, there is an unusual cartilage prong in the vulvar commissure and a clitoral lamina of unknown origin and composition that partially encircles the cartilage. These are possible subjects of future study.

Effects of Starvation on Matrix-Metalloproteinase 2 Expression in the Larval fat body of Drosophila melanogaster
(2024-05-21) Wolfel, Zoe; Woodard, Craig
Insulin sensitivity declines with age in mammals, leading to diseases such as type 2 diabetes and obesity, yet the precise mechanism is not well understood. The modulation of insulin signaling is implicated in the pathogenesis of the diseases and plays a critical role in various metabolic processes. The matrix-metalloproteinase (MMP) are a family of multifunctional Zn2+-dependent protease enzymes that play a role in tissue development, cell organization, and cell cycle control in mammals and the model organism Drosophila melanogaster which are a great model organism for research because it has a rapid life cycle, is small and easily cultured, male and female individuals are easily differentiated, and they share 75% similarity to all human genes implicated in disease. (Guo et al., 2022). Many MMPs are attached to the cell membrane by the protein glycosylphosphatidylinositol (GPI), which allows them to interact with the extracellular matrix (ECM). In Drosophila there are two MMPs: MMP1 and MMP2 which together degrade ECM components (Jia et al., 2014). I investigated the role of MMPs in the regulation of insulin signaling. Past studies have examined the indirect involvement of Drosophila MMP2 in insulin signaling (Bond, 2010). Along with a homolog for MMP2, MMP14 direct cleavage of insulin receptor in a murine model, consequently suppressing insulin signaling. In my investigation, I studied the role of MMP2 in insulin signaling during larval development by performing starvation experiments. I hypothesize that starvation induces MMP2 expression to allow MMP2 to cleave insulin receptor, which shuts off insulin signaling, allowing autophagy and nutrient release to occur. In order to test this hypothesis I have examined MMP2 transcript levels in the fat bodies of fed and starved third instar larvae using real time quantitative Polymerase Chain Reaction (PCR). The results of my experiments support my hypothesis that higher MMP2 transcript levels are observed in a starved condition compared to a fed control.

A Laughing Matter: Translating the Humor of Catullus
(2024-05-21) Moon, Lila; Arnold, Bruce
Catullus, an innovative and sharp-tongued poet writing during the late Roman republic, has engaged generations of scholars and students alike with his unique wit. Generally, however, the humorous aspect of his poetry is overlooked in academic settings, especially when it comes to translations of his work. Beyond engaging readers, Catullus’ humor reveals many things about the society in which he lived. In this thesis, I explore how we can communicate Catullus’ humor in translation, so that those who do not read Latin may enjoy his poetry and the knowledge that comes with understanding it. Catullus’ work, and especially the humor of his work provides an accessible point of entry into the Roman republic, one of the richest and most enlightening periods of Roman history. In analyzing Catullus’ unique sense of humor, I consider his work through the lenses of two major philosophical theories of humor, as well as through the lens of the literary tradition that inspired the poet. Within this thesis, I offer my own translations of a selection of Catullus’ work in order to prove the feasibility of translating his humor and to demonstrate how this goal should be achieved. I also provide commentary on my translations in order to explain the choices I made to best display Catullus’s humor.

Blessed Politics: Christian Zionism, the Prosperity Gospel, and American Policy toward Israel
(2024-05-20) Gallery, Lela; Hashmi, Sohail; Hilton, Adam; Barba, Lloyd
Whenever scholars explain the belief system behind Christian Zionism, many scholars cite a complex theological worldview called premillennial dispensationalism. According to this theology, Jews must return to their homeland of Israel for the second coming of Jesus to happen. While this worldview certainly plays a role in Christian Zionist activism, there is another overlooked belief system which impacts this political movement: the prosperity gospel. Since the rise of charismatic Christians into political activism in the 1980s, Christian Zionism has become less about speeding up the end times and more about blessing Israel to gain God’s favor. This project has two goals: 1) to argue that Christian Zionism is a political movement and 2) to show how the prosperity gospel has impacted American policy toward Israel via Christian Zionism.
