Wet, Flowering, Dry, Caroline A. Minchew

Theses and Dissertations

Wet, flowering, dry is a series of photographic works that explore how vernal pools are a macrocosm for holding memory and a site of omnipresent solitude and decay. This installation distills an embodied and ephemeral experience of how we are grounded in a network of invisible connections with our surroundings. This network becomes evident through biological, historical, and field research conducted at the vernal pools for over a year. Through slow observation and consideration of how multiple stories of place can weave together into a larger parable, Wet, flowering, dry reveals how the life cycle of a vernal pool is …

Modification Of Culture Medium And Identification Of Microbial Contaminants For Improved In Vitro Propagation Of Freshwater Mussels, Raquel M. Wetzell

Theses and Dissertations

In vitro propagation efforts play an essential role in conserving and restoring threatened freshwater mussel populations by circumventing the need for a fish host. Across a broad range of taxa, transformation is induced with an artificial M199 medium and rabbit serum. However, such formulation may not be sufficient in culturing critical species with more specific physiological requirements. In this study, multiple serum mixtures were tested to improve in vitro transformation of two freshwater mussel species: yellow lampmussel (Lampsilis cariosa) and tidewater mucket (Atlantaconcha ochracea). These species were selected because they parasitize similar fish host species but …

Evaluating Population Genetic Structure And Potential Genomic Signals Of Natural Selection In A Migratory Songbird (Protonotaria Citrea), Tyler A. Hohenstein

Theses and Dissertations

In this study I attempted to further resolve the population genetic structure in the Prothonotary Warbler (Protonotaria citrea), and conducted an outlier SNP analysis and exploratory gene ontology analysis to investigate potential ongoing natural selection in the species. This analysis of population structure confirms previous work by DeSaix et al. (2019), where weak population structure was observed between eastern sites along the Atlantic Coastal Plain, and western sites in the Mississippi Alluvial Valley, possibly due to a genetic discontinuity across the Appalachian Mountains. I conducted two forms of outlier SNP analyses, a principal component analysis (PCA)-based approach to identify SNPs …

Founding Monsters, Maggie Colangelo, Bernard Means

Founding Monsters

The Founding Monsters comic book was created as a science-friendly graphical storytelling framework that tells the story of the Founding Fathers and their obsession with prehistoric megafauna, especially mastodons and giant ground sloths. Founding Monsters combines sequential art (e.g. comic book style) with historical and scientific data. The first mastodon (Mammut americanum) fossils were found in New York in the early 18th century. Later in the 18th century, Thomas Jefferson was sent fossils from what is now West Virginia for what were eventually identified as bones from a giant ground sloth (Megalonyx jeffersoni). The founding fathers, …

Searching For Gold: Using A Novel Land Cover Classification To Identify Multiscale Drivers Of Site Occupancy By A Flagship Species For Early-Successional Habitat Conservation, Baron Lin

Theses and Dissertations

Understanding habitat selection at multiple scales is an important step in guiding conservation programs and reversing species declines. This, however, is difficult for species that occupy early-successional habitats (ESH) due to a lack of accurate representation of shrub cover in publicly available land cover data. The Golden-winged Warbler (Vermivora chrysoptera; GWWA) is a threatened species of conservation concern and a flagship for ESH conservation. We used a novel, LIDAR-derived land cover classification that accurately identifies shrubs at a fine resolution (1m) to investigate how habitat composition and configuration influence GWWA site occupancy. We aggregated this same land cover …

Water Clarity At The River-Estuary Transition Zone: A Comparative Study Of The James, Mattaponi, And Pamunkey Sub-Estuaries, Rachel Henderson

Theses and Dissertations

Water clarity is a key parameter for monitoring water quality and often used to assess habitat suitability for submerged aquatic vegetation (SAV). Light attenuation, a measure of water clarity, is impacted by colored dissolved organic matter (CDOM), and by suspended particulates which include living and non-living components. We anticipated that the relative importance of these factors in regulating light attenuation would vary among the upper portions of three sub-estuaries differing in morphometry, hydrology, and degree of human influence. The James is characterized by eutrophic conditions and high algal abundance, whereas the Mattaponi and Pamunkey exhibit lower phytoplankton production. The Mattaponi …

Characterizing Community-Level Size Spectra In Piedmont Streams Of Virginia (Usa), Giancarlo Racanelli

Theses and Dissertations

Many aquatic communities demonstrate an inverse scaling relationship between average body mass and density. Using quantitative samples of macroinvertebrates and fishes, we modeled this relationship in three Piedmont streams where little empirical research has been conducted. The size spectra (SS) method, in which individuals are identified by size, not taxonomic identity, was used with linear regression to model density as a function of mass. Fish and benthic invertebrate samples were collected on simultaneous days during September, then used to develop community-level SS models (combined fish and invertebrate data) for each stream. Invertebrate samples were also collected from each stream in …

A Spatiotemporal Assessment Of Fish Assemblage Response To Land-Use Change And The Evaluation Of Edna Metabarcoding For Describing Diverse Fish Communities, Timothy M. Owen

Theses and Dissertations

Fish assemblages are often assessed as a biological proxy for environmental health. While humans value healthy environments for the ecosystem services and recreational opportunities they provide, it is increasingly evident that such resources can be paradoxically degraded by anthropogenic activities. In this investigation, we studied the relationship between different intensities of anthropogenic land-use change and habitat-driven fish assemblage response across multiple spatiotemporal scales. Secondarily, we explored the efficacy of eDNA metabarcoding against conventional electrofishing techniques for the purpose of describing complete fish communities. This study was conducted in the Tuckahoe Creek basin near Richmond, Virginia. This James River tributary serves …

Testing The Efficacy Of Surface Swab Sampling To Determine Post-Mortem Submersion Interval (Pmsi), Using The Microbiome Colonization Of Skeletal Remains Submerged In A Lotic Environment, Sarah Rose

Master of Science in Forensic Science Directed Research Projects

Estimating the post-mortem submersion interval (PMSI) can provide a valuable forensic tool for medicolegal death investigations involving victims discovered in aquatic environments. Previous studies conducted by Cartozzo et al. (2021) successfully demonstrated the use of microbial succession to create predictive models for the estimation of PMSI from submerged bone. Though effective, bone sampling requires time consuming processing techniques that result in destruction of decedent tissue. This study investigates the use of bone surface swabbing as an effective alternative method to bone sampling, with the goal of predicting PMSI using a simpler, non-invasive sampling technique. Porcine (Sus scrofa) skeletal remains (rib …

Mapping The Vcu Campus Food Environment, Heather N. King, John C. Jones, Dan J. Albrecht-Mallinger

Graduate Research Posters

Preliminary research from a related VCU faculty team indicated that roughly ⅓ of all VCU students experience some level of food insecurity. Inventions to remedy this dire situation will require a more complete picture of the campus food environment. This project documented aspects of that environment. Our research team surveyed vending machines within Monroe Park buildings and facilities, along with nearby corner stores that were easily accessible to the university. Our team employed two instruments from the nationally recognized Nutritional Environment Measure Survey (NEMS), a toolkit created by Penn State University, to determine the nutritional quality of the campus food …

Design Hub: Activating Community By Design, Ed Williams

Theses and Dissertations

MOTIVATION

At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”

This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …
