Doctoral Dissertations
N2O is a long-recognized greenhouse gas (GHG) with potential in global warming and ozone depletion. Terrestrial ecosystems are a major source of N2O due to imbalanced N2O production and consumption. Soil pH is a chief modulating factor controlling net N2O emissions, and N2O consumption has been considered negligible under acidic conditions (pH <6). In this dissertation, we obtained solids-free cultures reducing N2O at pH 4.5. Furthermore, a co-culture (designated culture EV) comprising two interacting bacterial population was acquired via consecutive transfer in mineral salt medium. Integrated phenotypic, metagenomic and metabolomic analysis dictated that the Serratia population excreted certain …

Species Richness Of Moths In Parks Surrounded By Varying Levels Of Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett
Science University Research Symposium (SURS)
Moths can act as indicators of environmental wellness due to their pollution sensitivity and the complexity of biodiversity required to support their life cycles. Urbanization can impact the occurrence of moths in protected green spaces. Higher moth species richness was hypothesized to occur in parks surrounded by more rural areas. Three metropolitan parks were chosen in the Nashville area: downtown, within a suburban neighborhood, and in a rural area. Tree canopy cover and degree of impervious surfaces were assessed for each park and surrounding area using iTreeCanopy. Moths were attracted to a white sheet using a mercury vapor bulb, UV …

Trees In Our City How A Tree And A Small Patch Of Dirt Inspired A Classroom, Zuleika Hines
Occasional Paper Series
As a new Director in a new school, I knew that I wanted the children to have a curiosity for nature. But to lead the children to a place of discovery, they would need the opportunity to observe, play, and engage in elements of nature that would support hands-on activities both in the classroom and outside. When the opportunity came for me to build my own early childhood program, I knew that I had a unique opportunity to incorporate elements of nature in the design of the classroom. But I wanted nature to be local and the trees of our …
Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary,

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy
Symposium of Student Scholars
Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km2 and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

Culled Lionfish Sexual Maturity Over A Four-Year Timespan, Christina Bland, Jurgen Hauer, Bilal Saleem, Noelle James
Symposium of Student Scholars
Lionfish are invasive in the Atlantic and the Caribbean. Like many other invasive species, they do not have any natural predators in these areas, so their population can grow unchecked. This can decrease the population of native fish species due to lionfish eating to excess. Because of their impact on native species, resource managers have incentivized lionfish hunting. Hunters were paid $6 USD for every pound of lionfish they brought in, so they possibly favored larger lionfish to increase their reward which would lead to an adaptive advantage for fish of smaller sizes. We hypothesized that the lionfish bounty program …

For Microcystis aeruginosa PCC 7806, temperature decreases from 26 °C to 19 °C double the microcystin quota per cell during growth in continuous culture. Here we tested whether this increase in microcystin provided M. aeruginosa PCC 7806 with a fitness advantage during colder-temperature growth by comparing cell concentration, cellular physiology, reactive oxygen species damage, and the transcriptomics-inferred metabolism to a non-toxigenic mutant strain M. aeruginosa PCC 7806 ΔmcyB. Photo-physiological data combined with transcriptomic data revealed metabolic changes in the mutant strain during growth at 19 °C, which included increased electron sinks and non-photochemical quenching. Increased gene expression was observed for …

Alfred Russel Wallace Notes 28. Wallace's 'Change Of Mind', Revisited, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) is best known for his work on the theory of evolution by natural selection, and studies on biogeography. This fame has not, however, prevented appraisals of his work that sometimes depart from rational interpretations of his actual words. In this study, the frequently-offered notion that his adoption of spiritualism in late 1866 caused him to reverse himself on the universality of natural selection is taken to task, with arguments linked to his own words on the subject.

Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D.
Georgia Journal of Science
Freshwater ecosystems are critical habitats for maintaining biodiversity, often providing refuge for organisms especially in urban settings. Baldwin County, GA is home to many freshwater lakes that are part of the Oconee River watershed. Despite ongoing water quality monitoring, aquatic macroinvertebrates are under studied in the area. Aquatic macroinvertebrate diversity of one forested and one residential lake in Milledgeville, GA was documented for the first time. Despite low sample size, community composition was significantly different between lakes, with 27 families in Lake Laurel (forested), 44 families in Lake Oliver Hardy (residential), and only 19 families collected from both lakes. Seasonal …

Textbook Tasks For Social Change: Instantiation Of Development Debates And Interposition Of Pedagogical Interventions In Media Literacy Education, John N. Ponsaran
Journal of Sustainable Social Change
As materialization of their discursive stance as instructional communicators and media producers, textbook authors instantiate various development debates as well as interpose a wide range of pedagogical interventions for critical reflection and adoption by learners. This qualitative study sought to situate these development debates and the counterpart pedagogical interventions within the context of textbook task design as an application and embodiment of social justice communication. The development debates serve as the proposed contexts for media text analyses, reflective exercises, case studies, and media production, among others. Correspondingly, the interposition of interventions allows students to make sense of and act upon …
D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures,

D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova
MANTER: Journal of Parasite Biodiversity
D-shaped nematode eggs in the feces of Rangifer tarandus are expected to be oxyurid nematodes (Nemata: Oxyurida) of the genus Skrjabinema. The species S. tarandi is considered species-specific for this host. There is no consensus regarding the cross-infection of reindeer and sheep with S. ovis and S. tarandi. The drawings proposed by descriptors complicate differential diagnostics. Micrographs of S. tarandi eggs obtained via light microscopy and scanning electron microscopy as well as photographs of S. ovis eggs and drawings made on their basis are proposed to confidently distinguish between representatives of these two species, taking into account morphometric data. Thus, …
