Behavioral Indicators Of Stress In Wild Savanna-Dwelling Chimpanzees (Pan Troglodytes) In Fongoli, Senegal, Leah T. Williams

Theses and Dissertations

Stress influences health, reproduction, social relationships, and survival in primates. I identified behavioral indicators of stress in wild chimpanzees (Pan troglodytes) and determined whether coping strategies varied between behavioral contexts. Coping behavior differed significantly across contexts and behaviors, indicating that coping behaviors are strategically utilized in different contexts and provide insight into the emotional regulation of chimpanzees.

Neuroprotective Effects Of Prophylactic Brivaracetam On Memory And Anxiety Following Traumatic Brain Injury, Sofia Dumic

Theses and Dissertations

Prophylactic brivaracetam (BRV) was evaluated in a rat TBI model for effects on behavior and serum tau. BRV reduced anxiety-like behavior with optimal dose-dependent effects at 2.1mg/kg, but did not affect working memory. Serum tau was detectable early post-injury, supporting its use as a biomarker.

The Role Of Exotic Plants In The Diet Of Black-And-White Colobus Monkeys (Colobus Guereza) In Kibale National Park, Uganda, Michelle Gaykov

Theses and Dissertations

Exotic plants have both positive and negative impacts on their environment. They may act as additional food sources for the local fauna or as competition for local flora or leading to changes within a landscape or ecosystem. To considere the role of exotics in primate diet, this study focused on the dietary role of exotic plant species in the diet of a leaf-eating foregut fermenting monkey, the black-and-white colobus monkeys (Colobus guereza) in Kibale National Park, Uganda. Int this study, I followed individuals in two groups of black-and-white colobus monkeys for 21 days recording their food intake (0700-1900). I also …

Two Major Ontario Hospital Labs Bought Research Dogs From U.S. Breeder With Troubled Pastdogs Bred For Scientific And Medical Testing Suffer Abuse As The Scientific Industry Increasingly Turns To Alternatives For Research., Allison Hunter, Mary Beech, Sami Marshak, Kate Morano

Capstones

The purpose-bred dog breeding industry for research is little known. Each year, thousands of dogs are bred for scientific and medical testing, supplied to research facilities by a handful of major commercial breeders. But gaps in enforcement and regulation have allowed abuses to persist, even as the industry increasingly turns to alternatives to animal testing. Animal rights advocates have been decrying the treatment of these dogs. A federal Inspector General report found lax oversight of the industry, raising further concerns about how dogs are treated. This story was reported in collaboration with the Investigative Journalism Bureau, based in Toronto, and …

Inhibitory Control In Asian Elephants, Gillian Schmitt

Theses and Dissertations

Inhibitory control is defined as the ability to suppress a prepotent motor response in favor of a more efficient or advantageous behavior, and is an important core executive function. Although elephants are known to behave flexibly and display other executive functions, there is currently little information available on if, and to what extent, they display inhibitory control. We tested 16 captive Asian elephants (Elephas maximus) (N = 8 males, 8 females) ranging in age from 4-years-old to 60-years-old at the National Elephant Institute in Thailand using a classic detour paradigm adapted to be more ecologically salient for them through the …

Individual Differences In Wild Asian Elephant Behavior: Links Between Innovation And Responses To Novelty Across A Mosaic Landscape, Sarah L. Jacobson

Dissertations, Theses, and Capstone Projects

An animal’s responses to a novel or changing environment are influenced by a number of behavioral traits and cognitive abilities associated with flexible decision making. Animals also exhibit strong consistency in some behavioral responses, described as personality traits, which may influence their ability to adjust to environmental changes. It is important to investigate both flexibility and consistency in behavior, as well as how these two characteristics interact with each other, to understand the range of individual variation in behavior and decision making within a species. This knowledge can also help us understand how some species and individuals within a species …

Thinking Blue / Writing Red: Marxism And The (Post)Human, Stephen C. Tumino

Publications and Research

Thinking Blue/Writing Red interrogates contemporary culture across a range of texts, from the pandemic (‘Covid’ and ‘Trump Speak’) to high theory (Melville's narratives) and popular culture (Beyoncé's ‘Formation’ and Super Bowl performance, Twin Peaks , metamodern ‘cli-fi’ films). Inspired by Derrida’s idea of the secret, Tumino examines the significance of social movements (Black Lives Matter, Occupy, alter-globalization) and naïve art (Darger, Ryden) to argue that these texts speak of the secrets that capitalism cannot speak. Contending that the cultural surfaces narrate only the ‘nonsecret,’ that to see the social logic of the culture one must dig into what Bruno Latour …

Caring Until It Hurts: A Survey Of Compassion Fatigue And Moral Injury Among Wild Animal Caregivers And Its Implications For Animal Welfare In Zoos, Aquariums, Rehabilitation Centers, And Sanctuaries, Nadiya L. Delgado

Theses and Dissertations

Caregivers for captive wild animals are fundamental to the overall care, welfare, and conservation of animals in their charge, fulfilling diverse and critical roles. Caring for others, whether humans or animals, exposes caregivers to compassion fatigue – a state of emotional and physical exhaustion resulting from prolonged empathetic engagement with those they assist, and moral injury – psychological distress that arises from actions, or the lack of them, which violate one's moral or ethical code. This distress can manifest as intense feelings of guilt, shame, or a sense of betrayal by oneself or others. These phenomena are pertinent in environments …

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 …

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 …

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 …

Monk parakeets are a species of parrot native to subtropical and temperate regions of Argentina, Brazil, Uruguay, Paraguay, and Bolivia that have been introduced to many parts of the world. Monk Parakeets have lived in Brooklyn, New York since the 1970s and many myths and legends surround how these birds came to live here. 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.

Seasonal Crop Foraging Habits Of Asian Elephants And The Response Of Farmers Near The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Scott J. Gulizio

Theses and Dissertations

The consequences of human-elephant-conflict are of concern to a range of interests, including conservation, animal welfare, and socio-economic initiatives. Loss of crops due to elephants is a particularly contentious issue and a multitude of elephant deterrents have been tried to help prevent or diminish crop-foraging. This study examines the seasonal crop-foraging habits of Asian elephants just outside of Salakpra Wildlife Sanctuary, Thailand. Specifically, we sought to analyze when the elephants would forage crops, for how long, and how farmer presence affected this behavior. Additionally, to better understand patterns of deterrent use, we cataloged which deterrents were deployed by the farmers …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera

Dissertations, Theses, and Capstone Projects

Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Dendritic Spine Density And Morphology In The Dorsolateral Striatum Following A High Fat Diet, Tikva Nabatian

Dissertations, Theses, and Capstone Projects

Obesity rates have been dramatically rising in recent years and in 2017-2018 more than 42% of adults in the United States were obese. Obesity is associated with numerous health problems, including cardiovascular disease, stroke, insulin resistance, and type II diabetes. The prevalence of highly palatable and calorically dense foods high in fats and sugars is a significant factor in the increase in obesity rates. Many suggest that palatable food affects the brain in ways similar to drugs of abuse, reinforcing the consumption of highly palatable foods in the same way drugs reinforce drug use. While numerous weight loss programs and …

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 …

Evidence Of Mirror Self-Recognition In Beluga Whales, Alexander Mildener

Theses and Dissertations

Four beluga whales (Delphinapterus leucas) were tested for mirror self-recognition at the New York Aquarium. The whales were exposed to a mirror and a non-reflective plexiglass control. Two whales, Natasha and Maris, demonstrated self-directed behavior and Natasha passed one mark-test. Two whales demonstrated compelling evidence for MSR.

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 …

Dietary Regulation Of Silent Synapses In The Dorsolateral Striatum, Allison M. Meyers

Dissertations, Theses, and Capstone Projects

Obesity and drugs of abuse share overlapping neural circuits and behaviors. Cravings for drugs of abuse increase during abstinence, a phenomenon known as incubation. In obesity, increased craving is observed in individuals during dieting. Diets often fail, with return to- or increase above- original weight. The extent to which this reflects an incubation phenomenon has not been carefully examined. One mechanism underlying incubation is the reemergence of a developmental mechanism called silent synapses. Silent synapses are 'temporary' synapses that are important for remodeling brain circuits. They are prevalent during early development but largely disappear by adulthood. Drugs of abuse increase …

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.

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 …

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.

The Cost Of Living In Larger Primate Groups Includes Higher Fly Densities, Jan F. Gogarten, Mueena Jahan, Sébastien Calvignac-Spencer, Colin A. Chapman, Tony L. Goldberg, Fabian H. Leendertz, Jessica M. Rothman

Publications and Research

Flies are implicated in carrying and mechanically transmitting many primate pathogens. We investigated how fly associations vary across six monkey species (Cercopithecus ascanius, Cercopithecus mitis, Colobus guereza, Lophocebus albigena, Papio anubis, and Piliocolobus tephrosceles) and whether monkey group size impacts fly densities. Fly densities were generally higher inside groups than outside them, and considering data from these primate species together revealed that larger groups harbored more flies. Within species, this pattern was strongest for colobine monkeys, and we speculate this might be due to their smaller home ranges, suggesting that movement patterns may influence fly–primate associations. Fly associations increase with …

Genetic Circadian Mosaics And The Clock Network’S Contributions To Sleep, Lukasz Widziszewski

Dissertations, Theses, and Capstone Projects

Circadian rhythms are physiological and behavioral changes which follow a 24-hour cycle. Drosophila Melanogaster’s circadian clock neuronal network (CCNN) has been identified and several subpopulations have been characterized based on previous studies; the classifications of subpopulations of neurons within the CCNN are based on a return of anticipatory locomotor activity preceding the two daily light transitions (Lights on = dawn/Lights off = dusk). The neurons responsible for the return of anticipatory morning locomotor activity have been referred to as the M-cells, the group of neurons known to rescue evening anticipatory locomotor activity have been termed the E-cells. In this …

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 …
