Title: Characterizing the soil microbiome and quantifying antibiotic resistance gene dynamics in agricultural soil following swine CAFO manure application
Description: As agriculture industrializes, concentrated animal feeding operations (CAFOs) are becoming more common. Feces from CAFOs is often used as fertilizer on fields. However, little is known about the effects manure has on the soil microbiome, which is an important aspect of soil health and fertility. In addition, due to the subtherapeutic levels of antibiotics necessary to keep the animals healthy, CAFO manure has elevated levels of antibiotic resistant bacteria. Using 16s rRNA high-throughput sequencing and qPCR, this study sought to determine the impact of swine CAFO manure application on both the soil microbiome and abundance of select antibiotic resistance genes (ARGs) and mobile element genes (erm(B), erm(C), sul1, str(B), intI1, IncW repA) in agricultural soil over the fall and spring seasons. We found the manure community to be distinct from the soil community, with a majority of bacteria belonging to Bacteroidetes and Firmicutes. The soil samples had more diverse communities dominated by Acidobacteria, Actinobacteria, Proteobacteria, Verrucomicrobia, and unclassified bacteria. We observed significant differences in the soil microbiome between all time points, except between the spring samples. However, by tracking manure associated taxa, we found the addition of the manure microbiome to be a minor driver of the shift. Of the measured genes, manure application only significantly increased the abundance of erm(B) and erm(C) which remained elevated in the spring. These results suggest bacteria in the manure do not survive well in soil and that ARG dynamics in soil following manure application vary by resistance gene.

Title: Critical Fabulation for Survival: Knowledge of Pre-colonial Gender in Igbo Culture to Sustain Queer Imaginings of Care
Description: Through legislation and social code, modern-day Nigeria has become a hostile and dangerous country for queer people. As a queer person of the Nigerian diaspora, I struggle to hold both my “queer” and “Nigerian” identities because they seem contradictory. In this paper, I detail my journey reckoning with these two seemingly dissonant parts of my identity. In my endeavor to find communal belonging in Nigeria and its diaspora, I turn to the archive of pre-colonial Nigeria to discover if the nation of my ancestry was always hostile towards queer people. In particular, I try to uncover the violence British colonialism introduced to Nigeria. In this paper, I draw on the work of Saidiya Hartman to contextualize and guide my research and archivally-driven quest for belonging. As I have matured into myself, I have grappled with the intersections of my Nigerian-American and queer identities. Recently, I learned how Saidiya Hartman's "critical fabulation," a method for being attuned to and coping with archival gaps, can be a tool for survival when multiple realities conflict (Hartman, 2008). I practice critical fabulation in my venture to grapple with my “contradicting” identities by researching and drawing on the history of gender in Nigeria to imagine a more inclusive nation. Further, in this essay, I co-opt W. E. B. Du Bois’ framework of double consciousness to describe the internal conflict I feel regarding the friction between my Nigerian heritage and my queer identity because of the violence modern-day Nigeria inflicts upon queer people (Du Bois, 2007). Throughout this auto-ethnography, I discuss my double consciousness that stems from the intersectional oppressive structures in my life, such as patriarchy, transphobia, and homophobia. Additionally, in this paper, I demonstrate how the act of critical fabulation allows me to reconnect with myself and my (pre-colonial) Nigerian heritage to imagine and create spaces where queer Nigerians and I can belong (Hartman, 2008, p. 11).
