Detecting Bacterial Species From Ancient Human Skeletal Samples, Ariel Owens, Daisy Mcgrath, Tsai-Tien Tseng
Symposium of Student Scholars
Diagnosis of tuberculosis (TB) via morphological analysis is difficult and often inconsistent. With next-generation sequencing (NGS), ancient host microbiomes can be subjected to metagenomic analyses for the detection of TB in silico. Suitable bioinformatic workflows are needed for reliable ancient DNA (aDNA) analysis of causative agents. This study aims to enhance available bioinformatic screening methods to create more suitable bioinformatic processes and generate insights in relation to TB.
This research utilizes publicly available NGS data accessed through the Sequence Read Archive (SRA) of the National Center for Biotechnology Information (NCBI). Initial quality control steps included adapter trimming with Trim …
Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, Tiffany Ly
Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, Tiffany Ly
Symposium of Student Scholars
All animals are influenced by their environment. For social species, this means that changes in group size or composition can have long-lasting effects on survival or reproduction. When these social species are placed in captivity and new individuals are introduced suddenly by zookeepers or researchers, these events can lead to stress by changing established dominance hierarchies. For example, these interactions can cause stress hormones—like cortisol in primates and humans—to be released in response to meeting unfamiliar individuals. We took advantage of an introduction event happening at a captive research and conservation facility to better understand how introducing a new female …
Impact Of Human Presence And Visual Access On Barking Behavior In Shelter Dogs, Emily W. Dowling, Jessie A. Catchpole, Christina M. Walthers, Madison J. Pattillo
Impact Of Human Presence And Visual Access On Barking Behavior In Shelter Dogs, Emily W. Dowling, Jessie A. Catchpole, Christina M. Walthers, Madison J. Pattillo
Symposium of Student Scholars
Shelters can be stressful for dogs due to lack of predictability and control, social isolation, and busy environments. Providing dogs with more social opportunities and environmental predictability may improve their welfare. Barking may indicate stress and contribute to noise levels that are harmful to dogs and people. We investigated the impact of human presence and line of sight on barking. We manipulated line of sight by partially removing a crate barrier to allow the dogs visual access to other dogs and a better view of the room. We collected data on barking on 17 focal dogs as well as overall …
Eradicating Zebra Mussels: What Works?, Elijah Davies
Eradicating Zebra Mussels: What Works?, Elijah Davies
Symposium of Student Scholars
The invasion of U.S lakes and rivers by the invasive species of zebra mussels called Dreissena polymorpha has caused catastrophic harm to the local ecosystem by reproducing and outcompeting native mussel species as well as harm to pipes leading into water sources by binding to surfaces and reproducing to the point that the mussels clog pipes. In addition, recreation areas must be closed due to the sharp shells making areas unusable. In the past, research has focused on individual molluscicides and their eradication of zebra mussels, as well as their effect on native flora and fauna. My research will contrast …
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Symposium of Student Scholars
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …

Symposium of Student Scholars
This paleopathological study aims to identify Mycobacterium tuberculosis complex (MTBC), Mycobacterium avium complex (MAC) and other Mycobacterium species in silico from skeletal samples that belonged to 28 Polish individuals in the Neolithic period under PRJNA422903 from the Sequence Read Archive (SRA). After next-generation sequencing (NGS), bioinformatics methods are heavily relied upon for identification of pathogens from complex samples. We implemented a bioinformatics pipeline, with custom-built databases, utilizing the following software tools: Trim Galore! and Kraken2. After adapter trimming, Kraken2 was used for taxonomic classifications. We have found that Mycobacterium is present in all 28 individuals. The average percentage of MAC …

Helping Stem Graduate Students Fall Into Research, Diana Hartle, Kelsey Forester
Transforming Libraries for Graduate Students
Each Fall and Spring semester, the UGA Science Library hosts a series of workshops for undergraduate and graduate students during one consolidated week focused on research needs. In the past year, librarians at the Science Library noticed a large and growing need for research and wellness support for our STEM graduate students. This led us to begin to collaborate with the graduate school, University Health Center, and other science and medical librarians. Through this collaboration, we reconstructed our semesterly workshop series to be tailored specifically to STEM graduate students. We offered workshops on citation management, tools for tracking scholarly presence, …
Science Students And Student Researchers: Outreach Challenges Facing A Satellite Librarian, Mason Brown
Science Students And Student Researchers: Outreach Challenges Facing A Satellite Librarian, Mason Brown
Transforming Libraries for Graduate Students
The CUNY (City University of New York) Advanced Science Research Center (ASRC) has a small group of postdoctoral science students who are primarily onsite for lab work. I was asked to develop a series of library workshops that would appeal to both the ASRC students, and the more traditional grad students at the Graduate Center (GC) main campus. Developing seminars that appeal to users as both students and as researchers simultaneously have been a rewarding challenge. I will discuss how I developed and modified these topics over the course of one semester for two different audiences, as well as the …
