This thesis is a description of the behavior of monk parakeets in Brooklyn, New York’s Greenwood Cemetery based on observations I conducted twice a week from January through October of 2023. Because of the unusual nature of this population of parakeets as well as their unique …

Using Motivation To Assess Affective States Of Captive Red Kangaroos (Macropus Rufus) In Response To Visitor Presence And Crowd Size In A Walk-Through Zoo Exhibit, Julia King

Theses and Dissertations

This study investigates how visitor presence influences affective states of captive red kangaroos housed in a walk-through zoo exhibit by using motivation to consume a food reward in desired vs undesired locations and with/without an additional challenge feeder as a proxy for affective state, while considering individual variation and personality.

The Case Of The Disappearing Owner: Do Dogs Show Behavioral Evidence Of Violation Of Expectation?, Rita Kanagat

Theses and Dissertations

The What the Fluff challenge became a series of viral YouTube videos that started in 2018. In the videos, a person stood behind a blanket in a doorway in front of their dog and lifted and lowered the blanket revealing and obscuring themselves, and finally disappearing with a final blanket drop. The dogs’ reactions were varied but were suggestive of a violation of expectation response. We conducted a community science study that employed methodologies consistent with the What the Fluff Challenge paradigm that were conducted in the owners’ homes with their dogs. Each owner was required to run a control …

Exploring Relationships Between Dog Training Approaches And Aggression, Fear, And Dog-Owner Relationship, Janee Wise

Theses and Dissertations

Abstract

The current study examined relationships between operant conditioning derived dog training techniques and aggression, fear, and dog-owner relationship. Participants (N = 326) completed two online surveys; 1) a survey created for this study measuring the frequency of use of 14 common dog training techniques, which were grouped into four categories based upon operant conditioning: positive reinforcement, negative punishment, positive punishment, and negative reinforcement and 2) the Canine Behavioral Assessment and Research Questionnaire (C-BARQ), which measured several factors related to dog behavior. There were no statistically significant results related to the use of positive reinforcement or positive punishment. However, dog …

Problem Solving In Chelonia With Comments On Behavior And Methodological Challenges, Mal Walton

Theses and Dissertations

This study presented, to a variety of Chelonia species, a one-solution puzzle box problem. Of the 15 turtles tested, 11 solved the task at least once. Because studies on problem solving in reptiles, specifically Chelonia, are relatively unprecedented, we provide an examination of our methodology, along with suggestions for improvement.

Gaze In Cats And Dogs, Michael Bogese

Theses and Dissertations

Domestic dogs (Canis lupus familiaris) developed many behaviors across domestication, one example being gaze behavior. Gaze is the crux of other behaviors that make dogs unique in human-animal dyads, including lookbacks, gaze-following, and participation in an oxytocin feedback loop. Gaze behavior may have been motivated and sustained by evergreen cooperative relationships between dogs and humans (e.g., hunting, service roles). One way to confirm this relationship is to compare dogs to a domesticated species that lacks a protracted history of companionship: the domestic cat (Felis catus). In this study, we compare the gaze duration to owners of …

The Role Of Nest Location On The Reproductive Success Of Piping Plovers Breeding At Rockaway Beach, New York, Clara I.D. Arndtsen

Theses and Dissertations

The study’s goal was to learn what aspects of the piping plover experience affect reproductive outcomes at Rockaway Beach Endangered Species Nesting Area. Nest location was found to help predict reproductive success. Nests further from American oystercatcher nests were likely to fledge more chicks. Reproductive success was low in 2021.

Investigating The Function Of Play Bows In African Wild Dogs (Lycaon Pictus), Michael Spiotta

Theses and Dissertations

Play bows are a recognizable communicative signal observed in many carnivores, most notably, members of the genus Canis. Various hypotheses have been set forth to describe the function of play bows within canid social play behavior. To date, evidence suggests that wolves (Canis lupus), domestic dogs (Canis familiaris), and dingoes (Canis lupus dingo) use this signal as a means to both initiate, as well as, resume play. These studies have not previously been replicated in members of the family Canidae who fall outside of the genus Canis. In this study, I analyzed …

Behavioral And Physiological Effects Of Heavy Metals On Fish: A Review And Preliminary Results, Diana V. Morales

Theses and Dissertations

Pollution, specifically heavy metal pollution, in various bodies of water has been a significant issue for decades. Research has been conducted on heavy metals and their effects on the environment, larger fish species, and humans since the 1970s (Skidmore, 1964; Adeniyi et al., 2007; Adeosun et al., 2015; Bawuro et al., 2018). It is known that zinc is a neurotoxin in some species and causes harm to the environment. It is also known that it causes harm to people if it is ingested or if they are exposed to it for long periods of time (Mahurpawar, 2015; Mizuno and Kawahara, …

An Exploration Of The Contextual Interference Effect On Trained Trick Retention In Companion Dogs (Canis Lupus Familiaris), Madeline Messina

Theses and Dissertations

The ability to enact behavior change is pivotal to dog training success. Currently, there are few studies informing the best training practices. This thesis sought to enhance current training practices by applying a human motor skill learning theory, the contextual interference effect (CI), to a trick-training paradigm with companion dogs.

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 …

Effects Of Feeding Enrichment On The Behavior Of Ex-Pet Ring-Tailed Lemurs (Lemur Catta), Amanda Rodriguez

Theses and Dissertations

Environmental enrichment is a prevailing tool used to enhance the welfare of captive species. Benefits of enrichment commonly range from promoting activity levels to reducing stereotypic/abnormal behavior. This study investigated the impact of two forms of feeding enrichment on the behavior of ring-tailed lemurs confiscated from the illegal pet trade.

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.

The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori

Theses and Dissertations

Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …

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

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.

Hungry Hungry Humpbacks: A Preliminary Study Of Lunge Feeding In The New York Bight, Samantha E. Smith

Theses and Dissertations

Humpback whales (Megaptera novaeangliae) have been observed feeding in the New York Bight (NYB). Humpbacks in this region have an increased potential for collisions with vessels. In this study, data of lunge feeding was analyzed to determine locations of lunge feeding, clusters of lunge feeding, and depths of lunge feeding.

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 …

Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani

Theses and Dissertations

Inequity aversion, a negative response to situations of unequal reward distribution, is a cognitive trait usually seen in social species. This capacity is thought to regulate cooperative relationships in intelligent, cognitively flexible animals. Giant pandas are a unique case in that wild populations are characterized as nonsocial, however captive populations are socially housed until sexual maturity. This allows for the study of a nonsocial species in a social context and thus the assessment of socio-cognitive flexibility across evolutionarily distant taxa. Here, we assessed whether the giant panda (Ailuropoda melanoleuca) displays inequity aversion by testing ten juveniles living at …

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Behavioral Differences Among Varyingly-Disturbed Populations Of Eastern Grey Kangaroos (Macropus Giganteus) In New South Wales, Australia, Francesca A. Iacobucci

Theses and Dissertations

Despite their iconic status, kangaroo spp. are often treated as pests in Australia due to perceived abundance and extensive grazing behaviors. With growing suburbanization, animals such as kangaroo spp., are forced to inhabit human-dominated areas. Little research has been done examining how different aspects of human-induced disturbance can varyingly affect the behavior of wild animals. Specifically, this study examined how varyingly-disturbed areas affect behaviors such as vigilance, foraging, joey emergence during the in/out stage of pouch emergence, and play in three eastern grey kangaroo (Macropus giganteus) populations. Results suggest that acute environmental disturbances (e.g., dogs barking or …

Evidence Of Incipient Song Divergence In A Hawaiian Population Of Warbling White-Eyes, Jesse D. Robinson

Theses and Dissertations

Natural or human-mediated founder events can lead to changes in avian communication signals, potentially impacting the trajectory of evolution. Warbling white-eye (Zosterops japonicus) was introduced from Japan to the Hawaiian Islands between 1929 – ca. 1937. I recorded primary songs in Hawai‘i (O‘ahu, Big Island) and collected archival recordings, then conducted a comparative analysis between introduced and native song types which revealed significant differences in the O‘ahu and Big Island populations. To test for behavioral responses that corresponded to these differences, I presented conspecific playback stimuli (intra-island, inter-island, native) to individuals in Hawai‘i (O‘ahu, Big Island). Big Island individuals increased …

To Click Or Not To Click: Does Clicker Use Influence The Efficacy Of Different Teaching Methods In Dog Training?, Sarah Fraser

Theses and Dissertations

This study examines the efficacy of clicker training when teaching dogs a cone targeting behavior via two positive reinforcement training methods: shaping and luring. Training method, but not clicker use, significantly impacted rate of behavior acquisition. Clicker use improved learning efficacy in luring conditions but did not impact cue fluency.

Shelter Dogs: The Effects Of Training On Proximity, Samantha K. Nigbur

Theses and Dissertations

Almost 700,000 dogs are euthanized in U.S. shelters every year (ASPCA, 2017). In order to increase their adoptability, this study examined the use of positive reinforcement and shaping to train dogs to spend time in proximity to people. The experimenter selected 45 subjects who remained at the back of their kennels when she approached them. Fifteen of the subjects were trained with the use of a clicker marker and 15 without the use of any marker. Fifteen subjects were simply exposed to the presence of the experimenter. It was found that training significantly increased the number of dogs that reached …

Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith

Theses and Dissertations

This study examined contrafreeloading—choosing a physical task to access food over free food—in two Grey parrots (Psittacus erithacus). Both birds contrafreeloaded for food of equal or higher value, but differed in which contrafreeloading task they preferred. Differences between the parrots are considered as individual preferences for self-reinforcing tasks.

Do Bats Forage At Different Heights When In The Presence Of Other Species?, Benjamin L. Wagenberg

Theses and Dissertations

Acoustic monitoring was used to examine whether bats forage at different heights in the presence of other species. The data indicate that the presence of other species does affect the foraging height of bats. This data can be used to increase effectiveness of other identification methods using acoustic monitoring.

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

A Comparative Assessment Of Working And Pet Dog Performance During A Visual Discrimination Reversal Learning Task, Laisuna Yu

Theses and Dissertations

Dogs play an increasingly important role in human society as companions but also in the working sector. The working dog industry is currently struggling to meet the high demands for working dogs across all sectors with only approximately half the dogs acquired reaching their intended careers. Current behavior and temperament assessments are lacking in standardization and objectivity when identifying successful working dogs, which has prompted the industry to re-evaluate the methods used when selecting dogs. Behavioral cognitive testing, including reversal learning, has proven to be a beneficial tool in assessing physical cognition in pet dogs and, more recently, in working …

The Maze Of Personality: Latency And Electric Organ Discharge In A Mormyrid Fish, Gnathonemus Petersii Gunther 1862 (Mormyridae, Teleostei), Abbey C. Lipe

Theses and Dissertations

Personality is individual differences in behavior, consistent across contexts. Among Gnathonemus petersii we investigated, we hypothesized that fish could be grouped by: (1) slow/fast maze performance, (2) low/high electric frequencies, (3) correlated latency and frequency. Our first two hypothesis were not supported. Our third hypothesis was partially supported.

Does Clicker Training Lead To Faster Acquisition Of Behavior For Dog Owners?, Brian J. Burton

Theses and Dissertations

Clicker training is a method of dog training that has increased in popularity over the past 20 years (Feng et al., 2017). However, while there has been an increased use of clicker training, studies examining the claims that clicker training leads to faster acquisition of new behavior (Skinner, 1951; Pryor, 1999) has only been investigated in a handful of studies with domesticated animals. In addition, all known published studies comparing a clicker-plus-food group to a food-only group have found no significant difference in acquisition of a novel behavior (Dorey & Cox, 2018; Feng et al. 2017), which suggests that a …
