Classifying Dogs’ Facial Expressions: Implications For Human Cognitive Social Evolution And Cross-Species Communication, Lauren Mitchell

Symposium of Student Scholars

Facial expressions have been considered outward expressions of internal behavioral states. There is evidence that both dogs and humans subscribe to the social learning theory to acquire contextual information from past experiences in connecting facial expressions to behaviors. Previous research has shown that people are able to read dog facial expressions; however, the research is inconsistent on whether this behavior is innate or learned, as well as if this ability extends to dogs of different facial morphologies. The goal of this study was to understand the extent of humans’ ability to read facial expressions of dog breeds with different facial …

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 …

Implications Of Visual Social Access On The Welfare And Behavior Of Shelter Dogs, Christina M. Walthers, Madison J. Pattillo, Jessie A. Catchpole, Lauren E. Faulkner, Lauren N. Mitchell, Allison L. Martin

Symposium of Student Scholars

Animal shelter environments have many stressful factors that impact the welfare of shelter dogs, such as lack of predictability and control, and social isolation. Social isolation has been found to increase abnormal behavior and lead to poorer adoption outcomes. Providing visual access to shelter dogs is a relatively easy environmental modification that increases social opportunities and allows for more predictability and control over the environment, potentially improving welfare. To investigate the impact of visual access on the behavior of dogs, we used a within-subject design, conducting 5-min focal observations four times weekly before, during, and after visual access was provided …

Effects Of Essential Oils On Shelter Dog Behavior, Madison Pattillo

Symposium of Student Scholars

Shelter environments are stressful for dogs due to loud noises and unfamiliar surroundings. Dogs rely heavily on scent information, and exposure to some scents has shown reductions in activity and vocalizations in shelter dogs. We investigated the effects of two calming (lavender and vetiver) and two stimulating (lemon and rosemary) essential oils on crate position and active, resting, and stress behaviors. Observations were conducted for 5-min intervals eight times per week, with observations split between baseline and scent exposure. Our preliminary analysis using the Wilcoxon Signed-Rank test found that dogs exposed to lavender (n = 13), lemon (n = 9), …

The Effects Of Olfactory Enrichment On Shelter Dog Behavior, Madison J. Pattillo, Lauren N. Mitchell, Jessica A. Catchpole, Allison L. Martin

The Kennesaw Journal of Undergraduate Research

Shelter environments are stressful for dogs due to loud noises and unfamiliar surroundings. Previous research showed that exposure to some scents resulted in reductions in activity and vocalizations in shelter dogs. We investigated the effects of two calming (lavender and vetiver) and two stimulating (lemon and rosemary) essential oils on crate position and active, resting, and stress behaviors. There were 8, 5-min observations conducted each week per dog, split between baseline and scent exposure. Our analysis using the Wilcoxon Signed-Rank test found that dogs exposed to lavender (n = 13), lemon (n = 10), rosemary (n = …

Understanding How Temperature Influences European Starling’S Reproductive Success, Grace Fatoyinbo, Sarah Guindre-Parker

Symposium of Student Scholars

Many habitats face fluctuating temperatures year round. The animals that live there are typically able to adjust their behaviors to match these conditions. When temperatures become too extreme, however, it could potentially start having a negative effect on the animal’s reproductive success. In birds, for example, severe climate can affect their eggs and nestlings due to nestlings lacking the ability to thermoregulate. The parents then have to bear the responsibility of thermoregulation for their young, through a behavior called incubation or brooding. European starlings (Sturnus vulgaris) are a species of birds common across the United States where both …

Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson

Master of Science in Integrative Biology Theses

The sea urchin Lytechinus variegatus is a known grazer of the seagrass Thalassia testudinum, and has been known to denude vast stands of seagrass beds at high densities. Outside of these denudation events, the effects of sea urchins on seagrass are poorly understood. This study examines the effects of L. variegatus on T. testudinum in situ, to understand how sea urchins are affecting seagrasses in situ. Results indicate that urchins were found in the offshore portion of the seagrass bed at densities up to 4 urchins/m². Changes in temperature and sediment size in the bay indicate …

Pink Is The New Bull: The Feminization Of Pit Bulls In Visual And Literary Discourses As A Rescue Tactic, Stephanie Hogue

Master of Arts in American Studies Capstones

Since the 1980s, pit bulls have been portrayed in a raced, classed, and gendered national discourse that has associated them with minority males of color in low-income urban areas. This discourse has led to a villianization of the breed that has resulted in restrictions on pit bulls and their owners. This project seeks to explore the raced, classed, and gendered representations of pit bulls in cultural productions and the nuanced ways in which the intersectional identities ascribed to pit bulls have impacted their status as acceptable pets in the United States.

I aim to demonstrate that through visual and literary …
