Domarchive: A Century Of Published Dominance Data, Eli D. Strauss, Alex R. Decasien, Gabriela Galindo, Elizabeth A. Hobson, Daizaburo Shizuka, James P. Curley

School of Biological Sciences: Faculty Publications

Dominance behaviours have been collected for many groups of animals since 1922 and serve as a foundation for research on social behaviour and social structure. Despite a wealth of data from the last century of research on dominance hierarchies, these data are only rarely used for comparative insight. Here, we aim to facilitate comparative studies of the structure and function of dominance hierarchies by compiling published dominance interaction datasets from the last 100 years of work. This compiled archive includes 436 datasets from 190 studies of 367 unique groups (mean group size 13.8, s.d. = 13.4) of 135 different species, …

Carpe Diem: Winner And Loser Effects Are Constrained To Same-Day Competitions In Collegiate Baseball, Omar Tonsi Eldakar, Natalie Buckwold, Andrew C. Gallup

Biology Faculty Articles

Competitive outcomes can be significantly influenced by previous experience of winning and losing, whereby all things considered, winners are likely to continue winning and losers are likely to keep losing. Although short-lived, the underlying hormonal changes associated with these effects have been observed into the following day. Here, we assess the functional persistence of winner and loser effects in college baseball by investigating outcomes (splits vs. sweeps) of multigame series played over one or more days. Results show that sweeps occur at disproportionately higher frequencies in single-day series, but drop off to expected levels for multiday series.

Rebecca Fillyaw Ms Thesis Data For Publication In The Journal Sustainability, Rebecca Fillyaw, Melinda Donnelly, Linda Walters

CEELAB Research Data

By combatting erosion and increasing habitat, mangrove living shorelines are an effective alternative to hard-armoring in tropical and subtropical areas. An experimental red mangrove living shoreline was deployed within Mosquito Lagoon, Florida, using a factorial design to test the impact of mangrove age, breakwater presence, and mangrove placement on mangrove survival within the first year of deployment. Mixed mangrove age treatments were included to identify if seedling (11-month-old) survival could be enhanced by the presence of transitional (23-month-old) and adult (35 to 47-month-old) mangroves. Environmental factors were monitored to detect possible causes of mangrove mortalities. Approximately half (50.6%) of mangroves …

Development Of Alveolar-Capillary-Exchange (Ace) Chip And Its Application For Assessment Of Pm2.5-Induced Toxicity, Mingyang Gang, Song Tang, Haiyun Chang, Yuanyuan Chen, Fengge Chen, Ying Mu, Dong Zhao, Weiwei Fan, Huifang Tian, Diane Darland, Ying Zhang

Biology Faculty Publications

Although standard two-dimensional (2D) cell culture is an effective tool for cell studies, monolayer cultivation can yield imperfect or misleading information about numerous biological functions. In this study, we developed an alveolar-capillary exchange (ACE) chip aiming to simulate the cellular microenvironment at the alveolar-capillary interface. The ACE chip was designed with two chambers for culturing alveolar epithelial cells and vascular endothelial cells separately, which are separated by a microporous polycarbonate film that allows for the exchange of soluble biomolecules. Using this model, we further tested the toxic effects of fine particulate matter (PM2.5), a form of airborne pollutant known to …

Desktop Scanning Electron Microscopy In Plant-Insect Interactions Research: A Fast And Effective Way To Capture Electron Micrographs With Minimal Sample Preparation, Sakshi Watts, Ishveen Kaur, Sukhman Singh, Bianca Jimenez, Jesus Chavana, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The ability to visualize cell and tissue morphology at a high magnification using scanning electron microscopy (SEM) has revolutionized plant sciences research. In plant-insect interactions studies, SEM based imaging has been of immense assistance to understand plant surface morphology including trichomes (plant hairs; physical defense structures against herbivores (Kaur and Kariyat, 2020a, 2020b; Watts and Kariyat, 2021), spines, waxes, and insect morphological characteristics such as mouth parts, antennae, and legs, that they interact with. While SEM provides finer details of samples, and the imaging process is simpler now with advanced image acquisition and processing, sample preparation methodology has lagged. The …

Simplifying The Development Of Portable, Scalable, And Reproducible Workflows, Stephen Piccolo, Zachary E. Ence, Elizabeth C. Anderson, Jeffrey T. Chang, Andrea H. Bild

Faculty Publications

Command-line software plays a critical role in biology research. However, processes for installing and executing software differ widely. The Common Workflow Language (CWL) is a community standard that addresses this problem. Using CWL, tool developers can formally describe a tool’s inputs, outputs, and other execution details. CWL documents can include instructions for executing tools inside software containers. Accordingly, CWL tools are portable—they can be executed on diverse computers—including personal workstations, high-performance clusters, or the cloud. CWL also supports workflows, which describe dependencies among tools and using outputs from one tool as inputs to others. To date, CWL has been used …

Algal Biodiversity Survey Of The Middle Chattahoochee River Using Dna Metabarcoding, Amanda Howell

Theses and Dissertations

Aquatic plants play vital roles in water systems by providing ecological services, and one group that is understudied is algae. Algae play a crucial role in water systems as bioindicators and primary producers. They can be challenging to identify with the naked eye, so researchers have been using DNA metabarcoding, where DNA belonging to specific taxa can be isolated and identified from water samples. The objective of this study was to conduct an algal biodiversity survey on the middle Chattahoochee River system in Georgia. Water samples (1L) were filtered and sent to RTL Genomics for sequencing and processing; the data …

Vps54 Regulates Lifespan And Locomotor Behavior In Adult Drosophila Melanogaster, Emily C. Wilkinson, Emily L. Starke, Scott A. Barbee

Biological Sciences: Faculty Scholarship

Vps54 is an integral subunit of the Golgi-associated retrograde protein (GARP) complex, which is involved in tethering endosome-derived vesicles to the trans-Golgi network (TGN). A destabilizing missense mutation in Vps54 causes the age-progressive motor neuron (MN) degeneration, muscle weakness, and muscle atrophy observed in the wobbler mouse, an established animal model for human MN disease. It is currently unclear how the disruption of Vps54, and thereby the GARP complex, leads to MN and muscle phenotypes. To develop a new tool to address this question, we have created an analogous model in Drosophila by generating novel loss-of-function alleles of the …

Intein Inhibitors As Novel Antimicrobials: Protein Splicing In Human Pathogens, Screening Methods, And Off-Target Considerations, Diana A. Wall, Chunyu Wang, Kenneth Mills, Christopher W. Lennon

Faculty & Staff Research and Creative Activity

Protein splicing is a post-translational process by which an intervening polypeptide, or intein, catalyzes its own removal from the flanking polypeptides, or exteins, concomitant with extein ligation. Although inteins are highly abundant in the microbial world, including within several human pathogens, they are absent in the genomes of metazoans. As protein splicing is required to permit function of essential proteins within pathogens, inteins represent attractive antimicrobial targets. Here we review key proteins interrupted by inteins in pathogenic mycobacteria and fungi, exciting discoveries that provide proof of concept that intein activity can be inhibited and that this inhibition has an effect …

Avian Reproductive Success Is Associated With Multiple Vegetation Characteristics At An Active Grassland Restoration Site In Central Georgia, Kayla Allen, Katie Stumpf

Georgia Journal of Science

Grassland bird populations are experiencing major declines due to habitat degradation, pesticide use, and fire suppression throughout North America. Large-scale grassland restoration efforts to improve and provide suitable habitat are ongoing, but there is little data on productivity of birds breeding in restored habitats, nor on the impact of specific vegetation characteristics on reproductive success. Since 2005, agriculture fields at Panola Mountain State Park in central Georgia have been undergoing restoration to warm-season grasslands; however, until now, data on nest success or productivity was lacking. The goals of this project were to: (1) quantify reproductive success and (2) determine which …

A Bioinformatic And Biochemical Analysis Of Cruciviruses, George William Kasun

Dissertations and Theses

Cruciviruses are novel ssDNA viruses discovered through metagenomics and direct environmental DNA amplification and cloning. The genomes of cruciviruses suggest that gene transfer between RNA and DNA viruses occurred due to the presence of putative protein-encoding genes that are homologous to both ssRNA and ssDNA viruses. In order to gain a better understanding of this group of viruses both bioinformatic analyses and in vitro biochemical experiments were employed. The results of the bioinformatic analyses show that cruciviruses are a highly diverse group of ssDNA viruses. Their placement within established ssDNA phylogenies is difficult due to heterogeneity in their putative replication-associated …

The Behaviors Of A Captive Father-Daughter Pair Of Ateles Geoffroyi Geoffroyi, Felicia Gordian

The Pegasus Review: UCF Undergraduate Research Journal

The Central Florida Zoo and Botanical Gardens intends to introduce new members to the black-handed spider monkeys (Ateles geoffroyi geoffroyi) enclosure. The behavioral analysis of captive animals within their human-made zoo environments is pertinent information for zookeepers before such an introduction can be made. To contribute to that goal, this study observed the behaviors of a father-daughter pair of black-handed spider monkeys. This study observed their vocalizations, habitat utilization, enrichment utilization, conspecific interactions, and interactions with humans to better understand how they interact with their environment as well as their group dynamics. This behavioral baseline can then be utilized to …

Synapsej: An Automated, Synapse Identification Macro For Imagej, Juan Felipe Moreno Manrique, Parker R. Voit, Kathryn E. Windsor, Aamuktha Reddy Karla, Sierra R. Rodriguez, Gerard M.J. Beaudoin Iii

Biology Faculty Research

While electron microscopy represents the gold standard for detection of synapses, a number of limitations prevent its broad applicability. A key method for detecting synapses is immunostaining for markers of pre- and post-synaptic proteins, which can infer a synapse based upon the apposition of the two markers. While immunostaining and imaging techniques have improved to allow for identification of synapses in tissue, analysis and identification of these appositions are not facile, and there has been a lack of tools to accurately identify these appositions. Here, we delineate a macro that uses open-source and freely available ImageJ or FIJI for analysis …

Molecular Analysis Of Mchm Toxicity In Zebrafish, Cassandra Pelton

Honors College Theses

In early 2014 Freedom Industries, located in Charleston, WV, leaked approximately 10,000 gallons of 4-methylcyclohexane methanol into the Elk River. This river serviced approximately 300,000 people as a source of municipal water. Its effects on the people and surrounding wildlife is largely unknown.

Chemicals in surface runoff have the potential to induce aquatic animal trait changes, such as altered movement and feeding, that can ultimately alter predator-prey dynamics in aquatic systems. However, chemicals with high potential to enter aquatic systems, like 4-methylcyclohexane methanol (MCHM) used to clean coal, were tested using only short-term, single-species studies prior to use. Data from …

Salicylic Acid: A Key Regulator Of Redox Signalling 1 And Plant Immunity, Mohd Saleem, Qazi Fariddudin, Christian Castroverde

Biology Faculty Publications

In plants, the reactive oxygen species (ROS) formed during normal conditions are essential in regulating several processes, like stomatal physiology, pathogen immunity and developmental signaling. However, biotic and abiotic stresses can cause ROS over-accumulation leading to oxidative stress. Therefore, a suitable equilibrium is vital for redox homeostasis in plants, and there have been major advances in this research arena. Salicylic acid (SA) is known as a chief regulator of ROS; however, the underlying mechanisms remain largely unexplored. SA plays an important role in establishing the hypersensitive response (HR) and systemic acquired resistance (SAR). This is underpinned by a robust and …

The Coastal Monitor: Vol. 7 No. 3, John Tanacredi Ph.D.

The Coastal Monitor

Where has all the pollution gone? No hazardous toxic algal blooms? Incredible summer estuarine water quality! No fish kills. Banner years in recreational fisheries for Stripers and Blues and incredible numbers of Humpback whales! No going to restaurants, so greater at home use of water and septic systems! Since March 2020, drier years than most, thus reducing runoff with fertilizers and organic pesticides, resulting in reduced water contamination. So maybe, just maybe, this COVID- 19 period which has altered our collective lives forever, has also resulted in a grand experiment on what has been hiding in plain sight? That is, …

Roles Matter: Graduate Student Perceptions Of Active Learning In The Stem Courses They Take And Those They Teach, Lorelei E. Patrick, Leigh Ann Howell, Everett William Wischusen

Biological Sciences Faculty Publications

Despite many calls to reform undergraduate science, technology, engineering, and math (STEM) education to incorporate active learning into classes, there has been little attention paid to graduate level classrooms or courses taught by graduate students. Here, we set out to understand if and how STEM graduate students’ perceptions of active learning change in the classes they take versus those they teach. We found that graduate students had taken relatively few graduate level classes using active learning and they felt that more time should be devoted to active learning in the courses they were taking. Teaching assistants felt that they were …

Cardiovascular Health Intervention In Firefighters, Kyle T. Manuel

Selected Honors Theses

As each year passes, a fatal cardiovascular event continues to be the leading cause of death among on-duty firefighters. Risk factors for a fatal cardiovascular event and cardiovascular health disease (CVD) are obesity, sleep deprivation, weight gain, lack of exercise, unhealthy diet, etc. The research in this thesis lays out the poor association between cardiovascular health and firefighters. Interventional programs that aim to improve the cardiovascular health of firefighters must be implemented universally to all fire departments by the International Association of Firefighters. Pertinent information collected on the cardiovascular health of surveyed firefighters of Hernando County was paradoxical. While most …

Testing The Role Of Wfs1 In Calcium Regulation In Drosophila Cells, Briana Scott, Alyandra Lee

Fall Showcase for Research and Creative Inquiry

The purpose of the project is to knock out the Wfs1 gene in Drosophila (fruit fly) cells and test the hypothesis that this gene is involved in regulating intracellular calcium levels. To test this hypothesis, the gene will first be knocked out using CRISPR-Cas9 molecular tools that are readily available in Dr. Shanle's lab. This will effectively inactivate the Wsf1 gene in cells. To do this, we will transfect Drosophila cells with CRISPR-Cas9 targeting the gene. Next, we will confirm that the gene is mutated using genomic DNA purification, polymerase chain reaction, and sequencing. Finally, we will treat cells with …
