Behavioral Patterns Of Goldfish (Carassius Auratus) Exploring A “Fish Tower”, Sasha Prasad-Shreckengast Dec 2021

Behavioral Patterns Of Goldfish (Carassius Auratus) Exploring A “Fish Tower”, Sasha Prasad-Shreckengast

Theses and Dissertations

Fish are held in captivity at some of the highest numbers of any taxa, but their curiosity is rarely studied. With this study, we set the groundwork to investigate the presence and nature of curiosity in goldfish (Carassius auratus) via novel free-choice exploration opportunities by creating a “fish tower."


Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph Dec 2021

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …


Mucinomics: A Bioinformatic Analysis Of Snail Mucins, And Their Function, Maxwell B. Mcdermott Aug 2021

Mucinomics: A Bioinformatic Analysis Of Snail Mucins, And Their Function, Maxwell B. Mcdermott

Theses and Dissertations

This thesis outlines the current research on secreted snail mucus, highlighting the potential of this biopolymer, and also demonstrates a research strategy to fulfill the unmet need of examining the hierarchical structures that lead to the enormous biological and chemical diversity of snail mucus genes.


Uncovering Potential Biofilm Modulators, Liliana Margent May 2021

Uncovering Potential Biofilm Modulators, Liliana Margent

Theses and Dissertations

Biofilms have negative and positive impacts depending on the context they develop. In this work, I optimized a biofilm assay to evaluate the effect of three different types of compounds indole derivatives, 2,5 Diketopiperazines, and 12-hydroxystearic acid on the biofilm formation of E. coli.


Some (Im)Material Girls, Living In (Im)Material Worlds, With Seeds, Stars, And Shit, Matthew Weiderspon May 2021

Some (Im)Material Girls, Living In (Im)Material Worlds, With Seeds, Stars, And Shit, Matthew Weiderspon

Theses and Dissertations

This writing situates material and gestural vocabularies cultivated in my artwork in relation to my lived experience; primarily my rural upbringing in Colorado. Scattered floor dispersals, calling sounds, and bodily movements desire reconsiderations of hope in precarity through a disorientation of place, association, scale, and language.


Pre- And Post-Partum Observations Of Signature Whistle Characteristics Of The Bottlenose Dolphin (Tursiops Truncatus), Robert Dutchen Apr 2021

Pre- And Post-Partum Observations Of Signature Whistle Characteristics Of The Bottlenose Dolphin (Tursiops Truncatus), Robert Dutchen

Theses and Dissertations

This study analyzes whistle usage in an Atlantic bottlenose dolphin during birth. Findings show the mother produces two predominant whistle contours. Congruities between the whistles were compared and showed that the type 1 contour bears structural similarity to the first component of the type 2 contour, indicating combinatorial whistle construction.


Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo Apr 2021

Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo

Theses and Dissertations

Wild lemur primates were tested for social preferences across behaviors. Study found highly conservative social preferences that were very consistent across all behavioral states, despite high fission fusion traits common of lemur groups. This finding lays the foundation for using nearest-neighbor as a proxy of social preference for future endeavors.


Influence Of Group Change On Scent Marking In A Wild Population Of Verreaux’S Sifaka (Propithecus Verreauxi), Julia C. Dickerson Apr 2021

Influence Of Group Change On Scent Marking In A Wild Population Of Verreaux’S Sifaka (Propithecus Verreauxi), Julia C. Dickerson

Theses and Dissertations

This study analyzed scent marking rates of wild Verreaux’s sifaka during dispersals to investigate the impact of group changes on olfactory communication. Our results indicate that scent marking is affected by changes in group structure, but other methods of communication likely play a larger role in mediating group membership changes.


Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai Apr 2021

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai

Theses and Dissertations

Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …


Design Of Fibril Forming Collagen Mimetic Peptides: Heterotrimers And Nucleation Domains, Sally Tan Jan 2021

Design Of Fibril Forming Collagen Mimetic Peptides: Heterotrimers And Nucleation Domains, Sally Tan

Theses and Dissertations

This paper attempts to design collagen mimetic peptides where the triple-helical region mimics that of human Type I Collagen. With consideration for chain selection and chain register, we utilize the NC2 domain of heterotrimeric Type IX Collagen as a nucleation domain for triple-helix folding.
