The Effects Of People, Time Of Day, And Season On Affiliative And Stereotypic Behaviors In Captive Rhinoptera Bonasus And Other Rays Across Two Human-Interactive Enclosures, Wren C. A. Newman

Theses and Dissertations

Cownose rays (Rhinoptera bonasus) are among the most common species found in aquaria, yet the impact of touch enclosures on their welfare remains largely unknown. While research on animal-visitor interactions has produced mixed results for other species, the lack of studies focusing on fish welfare poses a risk of overlooking potential welfare concerns. Therefore, we aimed to establish a baseline for cownose rays regarding stereotypic behaviors, sociality, and activity in captivity, and to examine the influence of human interaction on these behaviors. We collected over 700 hours of footage from two enclosures at Adventure Aquarium in Camden, NJ …

Enhancing The Visual Environment Of Indoor Housed Laboratory Cynomolgus Macaques (Macaca Fascicularis) To Reduce Stress And Maladaptive Behavior, Jeannine C. Rodgers

Theses and Dissertations

Nonhuman primates housed in indoor laboratory environments are generally exposed to nondescript background visual stimuli. This environment is not ideal for species whose primary sensory modality is visual. To provide a more naturalistic visual environment that would potentially improve their welfare, this study assessed the efficacy of a passive natural visual stimulus in the reduction of stress and stereotypy and agonistic behaviors in a cohort of four (2 male, 2 female) Cynomolgus macaques (Macaca fascicularis) housed in an indoor laboratory facility in New York City. The macaques were exposed to four different videos depicting scenes of natural landscapes that were …

The Effect Of The Lunar Cycle On The Demographics Of Asian Elephants Observed In Open Areas In A Protected Wildlife Sanctuary And Surrounding Crop Fields, Serene K. Rivera

Theses and Dissertations

Due to human development and habitat fragmentation, Asian elephants increasingly use human landscapes and encounter people. These interactions have led to negative interactions between humans and elephants, such as crop-raiding. Despite efforts to mitigate these conflicts, farmers have not been able to consistently protect their crops from elephant foraging. Therefore, it is important to understand elephant behavior in these landscapes to help create long term mitigation plans. Specifically, research regarding demographic patterns in Asian elephants’ perceived predation risk can inform wild elephant management. This study used camera traps in Salakpra Wildlife Sanctuary in Kanchanaburi, Thailand to observe the wild Asian …

Microplastic Accumulation In The Marsh Periwinkle (Littoraria Irrorata), Sarah Keaton, Hannah Lukhard, Eli Windy, Manar Hasan

DePaul Discoveries

Contamination of oceans by microplastics (mm) currently poses a major threat to aquatic and terrestrial ecosystems worldwide. Recent attention towards this issue has raised questions about the extent to which microplastics have accumulated in the environment, and has led to an increase in studies on the effects of microplastics in various organisms. However, levels of contamination in protected natural areas are still largely unexplored, yet can offer an important empirical perspective on the issue. In addition, little is known about the potential effects of microplastics on behavior in the field. This research was conducted within the protected ACE Basin National …

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …

Virtual Fencing In Livestock Management: Effects On Beef Cattle Stress And Enhancing Wildlife Conservation, Kaitlyn E. Dozler

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of virtual fencing on beef cattle stress and how implementing the technology can aid wildlife habitat conservation at the University of Nebraska Gudmundsen Sandhills laboratory (GSL) near Whitman, NE. First, I examined how virtual fencing influences acute heart rate changes in beef cattle fitted with the virtual fencing collars. No significant difference in the average heart rate of a cow (P > 0.05) was observed between the 30 min control and virtual fenced periods for both trial dates. Second, I examined the influence of topography on wildlife species richness and presence at GSL using wildlife camera …

A Comprehensive Analysis Of How Pet Ownership Impacts The Experiences And Well-Being Of Homeless Individuals, Alexandra G. Watson, Nancy A. Dreschel

People and Animals: The International Journal of Research and Practice

This paper conducts a thorough examination of the relationship between pet ownership and homelessness. In a context where homelessness in the United States is a growing concern, we delve into an aspect that has received little attention: how homeless individuals and their pets interact. Through an extensive review of existing research, this paper aims to uncover the demographic characteristics of homeless pet owners and understand the significant effects of this bond. Our findings reveal that homeless individuals with pets come from diverse backgrounds, including various ages, genders, and racial backgrounds. Their pets provide not only companionship but also emotional support, …

Socialization Procedure For An Adult Feral Cat In A Home Setting, Erica Serito

Thesis Projects

Of the nearly sixty million feral cats, most are deemed unadoptable and thereby unable to be rescuable given their aggressive behaviors towards humans. There are currently no evidence-based socialization training procedures used to socialize adult feral cats with the main interventions for the fearful adult feral cats being trap-neuter-return (TNR) or euthanasia. The purpose of the current study was to decrease undesirable behaviors of an adult feral cat to facilitate safe and reciprocal interactions between her and humans. The study evaluated the use of a differential reinforcement of other behavior (DRO) procedure without extinction on an adult feral cat to …

Phototaxis In The Terrestrial Isopod: A Mechanism For Investigating Invertebrate Learning And Memory, Christopher Buzzelli, Jessica Kent, Chelsea Pawlak, Kevin P. Kaut

Journal of Neuropsychology and Behavioral Processes

Isopods readily explore new environments and typically prefer contexts with lower levels of illumination (i.e., negative phototaxis). In the first of two behavioral experiments reported here, the ability of isopods to discriminate between light and dark nesting regions was confirmed, although evidence suggests an initial ‘instinctive’ draw toward a darker context. Extending these findings to experiment 2, isopods were trained against their negatively phototaxic tendency and had to exit a darkened start chamber in order to locate nesting material in a brighter chamber. Within-session improvements in latency to enter the nesting region were noted across training trials, coupled with evidence …

Technocene, Vir Joseph Naidu

Masters Theses

Embodied human communication within the Anthropocene. Existing at the intersection of technology, and the body.

The design industry has developed technology that is, paradoxically, isolating. The exposure to a vast audience in the digital sphere has introduced new societal pressures, leading to a disconnection from our immediate surroundings, detached, and donning metaphorical masks. Technocene lives on the fringes of the discipline by blending conceptual thinking with practical application. Through curious, experimental artifacts, it prompts us to shed our masks and embrace vulnerability. Technocene endeavors to reimagine the human experience by acting as a discursive design project. It probes the boundaries …

Human-Animal Interaction And Human Prosociality: A Meta-Analytic Review Of Experimental And Correlational Studies, Nicole Ruiying Chen, Nadyanna M. Majeed, Gloria J. Lai, Paye Shin Koh, Manmeet Kaur, K. T. A Sandeeshwara Kasturiratna, Zhi Yan Alycia Ho, Jose C. Yong, Andree Hartanto

Research Collection School of Social Sciences

Pet ownership and interactions with animals confer various physiological and psychological benefits to humans. Although interactions with animals are commonplace, there is no consensus in the literature on the actual impact of animal exposure on prosociality. Hence, this meta-analysis investigated 20 eligible studies (n = 4,116, k = 48) and provided an extensive examination into the different potential moderators of the relationship between human–animal interaction (HAI) and prosociality, such as the distinction between empathy and prosocial behavior, HAI characteristics, and sample characteristics. Overall, a small positive effect size was found (d = 0.22), suggesting that human exposure to animals is …

Towards More Inclusive Practices In Applied Linguistics: A Study Of Journal Editors’ Views On Using ‘Who’ With Nonhuman Animals With Implications For Language Education, Denise Dillon, George M. Jacobs, Meng Huat Chau

Journal of English and Applied Linguistics

Like racism or sexism, speciesism highlights how people fail to give due respect to nonhuman animals. After more than 20 years since the publication of Dunayer’s (2001) seminal work, Animal Equality: Language and Liberation, speciesism appears to remain a controversial issue. In this article, we explore the issue of speciesist language by considering the views of journal editors on one point raised in the seventh edition of the Publication Manual of the American Psychological Association (2020): that the relative pronoun who should only be used with humans and not with other animals. The results of this study suggest that while …

Sexual Selection And Mate Preference In Astatotilapia Burtoni, Anastasia Martashvili

Dissertations, Theses, and Capstone Projects

Social systems provide robust frameworks for the division of labor and the allocation of resources that improve the fitness of a community. These social systems are pervasive across the animal kingdom and are seen in various species of insects, mammals, birds, reptiles, and fish. Within social hierarchies, rank can be dynamic and modulated by changes in molecular and/or physiological substrates. These changes can shape various behavioral outcomes that lead to the reorganization of hierarchies and their communities. Specifically, the role of social behavior in African cichlids has been salient for their adaptive radiations in the East African Great Rift Lakes …

Public Perception Of Service, Therapy, And Emotional Support Animals In A College Setting, Elizabeth Demarse

Honors College Theses

The use of service dogs, emotional support dogs and therapy dogs continues to increase, they are likewise becoming more common on college campuses. However, outside of a 2017 survey into the general population, there is little data into the public’s ability to define these animals and their roles or how negative press affects trust in the legitimacy of these animals. Additionally, no research has been done into how this affects college students despite college campuses frequently being a location where assistance animal ownership is brought into question. An anonymous survey was conducted and distributed online to students at Murray State …

A Comparison Of Shaping And Imitation For Reducing A Dog’S Problem Behavior, Carlee Weir, Robbie Hanson

Theses

Over one million dogs have entered shelters in 2024 alone with approximately 31% of those dogs being relinquished by their owners (Shelter Animal Count, 2024). Further, non-aggressive behavioral issues are often cited as a primary cause for owner relinquishment (Best Friends Network Partners, 2018; Howard & DiGennaro Reed, 2014). Previous research has shown the effectiveness of training methods based on positive reinforcement to reduce problematic behavior with dogs and to increase desirable behavior, such as shaping and clicker training, and there has been a growing interest in the use of imitation during training. Fugazza and Miklosi (2015) compared a shaping …

A Preliminary Analysis Of Functional Communication Training Via Voice-Recorded Buttons To Reduce Undesirable Behaviors With Dogs, Mya Watson-Blake, Robbie Hanson

Theses

Undesirable behavior, such as excessive barking, jumping up, and biting, is prevalent among pet dogs with an estimate of 72%-85% of dogs exhibiting at least one type of undesirable behavior (Dinwoodie et al., 2019; Powell et al., 2021; Salonen et al., 2020). Further, canine undesirable behavior has been found to be the leading cause of owners relinquishing their dogs to rescue shelters (Powdrill-Wells et al., 2021). Functional communication training (FCT) is a method that has shown to be effective with human populations for reducing challenging behaviors by teaching an individual an alternative response that results in the same class of …

The Role Of Transit Countries In Global Wildlife Trafficking, Joseph Gangi

Student Theses

This thesis explores the role of transit countries in the global trade of illegal wildlife. While much research has been conducted on source and destination countries, transit countries remain an under-researched link in this chain, even though they play an integral role in facilitating this trade. This study utilizes the Rational Choice and Institutional Theory theoretical frameworks to examine the factors associated with transit countries' roles in wildlife trafficking. The findings indicate that transit countries play an active role in wildlife trafficking, and there is a need for policy to address this issue. Considering the findings of this study, this …
