The Passage Of The 2016 Ballot Question #3 In Massachusetts And Its Implications, Hannah Silverfine

Sustainability and Social Justice

In the 2016 Massachusetts primary election, ballot question #3, “Massachusetts Minimum Size Requirements for Farm Animal Containment”, aimed to improve welfare standards for cows raised for veal, female sows confined to gestation crates, and chickens caged for eggs. This study seeks to analyze the complex relationship between local and national food systems, and articulate the multi-level implications of Question 3. Research examines the rationale behind voting, campaign narratives, and campaign financing in Massachusetts, and ultimately compares the implications of Question 3 with those of California’s 2008 Prevention of Farm Animal Cruelty Act. The lenses of animal geographies and the political …

Do Non-Human Primates Have Gender?, Aaron Pelchat

Senior Honors Projects

As activism for trans rights and gender equality becomes ever more prevalent in the current American political discourse, so too has there been a rise in questions about gender. Are sexuality and gender linked? Aren’t there only two genders? What is the difference between gender and sex? Is there a difference? How does one DO gender? Isn’t gender just something you are born with? Helping the public understand these questions is important to transgender and gender non-conforming individuals in a time when more people are “coming out of the closet” and identifying as genders other than cisgender. As an anthropologist, …

Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd

Undergraduate Honors Theses

In this study, the effects of the neonicotinoid pesticide, thiamethoxam, are examined through the Proboscis Extension Response (PER) in honey bees (Apis mellifera). PER is a form of classical conditioning applied to honey bees through scent and reward association which quantifies learning rates. Results between groups treated with thiamethoxam did not differ significantly from untreated control groups. Potential reasons for these results are discussed. The method and experimental apparatus for testing the PER assay are also discussed.

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …

Does Personality Similarity In Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?, Kelsey R. Moreno

Master's Theses

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Grooming As An Agonistic Behavior In Garnett’S Small-Eared Bushbaby (Otolemur Garnettii), Jennie L. Christopher

Master's Theses

Social behaviors are a necessary component of group living and interactions between organisms. To correctly assess social interactions, researchers must be able to observe behaviors and interpret their function based on the behavior or the behavioral context. In primate species, grooming is often used to assess affiliations between group members and the consensus has been to always interpret grooming as an affiliative behavior. However, a number of avian, rodent and feline species have been shown to groom conspecifics aggressively. These instances of aggressive grooming appear most often when individuals are required to maintain close proximity to one another, such as …

Predatory Nature And Food Preferences Among Captive Otolemur Garnettii, Morgan N. Ruby

Honors Theses

Observing the predatory nature in primates has yielded knowledge pertaining to their biology and evolutionary pathways; however, not many studies have focused on the complexities of their food preferences. This thesis focuses on food preferences among Garnett’s Greater Bushbaby (Otolemur garnettii): a small-bodied nocturnal primate native to Central and Southern Africa. Presented food options were raisins: dried mealworms and raisins: live mealworms. The population consists of fifteen bushbabies housed in The University of Southern Mississippi (USM) Primate Behavior Research Facility. Ten trials of three different experiments were performed to identify the dominant hand and food preferences among the …

Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier

Dissertations

Alcohol abuse is the third largest risk factor for disease world, responsible for an estimated 3.3 million deaths each year. The concomitant ingestion of alcohol and caffeine is hypothesized to increase risk factors associated with alcohol use alone by reducing subjective effects of intoxication. The zebrafish (Danio rerio) has recently garnered attention from researchers as an effective pre-clinical in-vivo animal model in behavioral pharmacology research, largely due to small size, low-cost and ease of drug delivery. A number of studies have reported the effects of alcohol and caffeine on zebrafish behavior at a variety of doses. However, the …

Efficacy Of Cognitive Enrichment For Bottlenose Dolphins (Tursiops Truncatus): Evaluation Of Planning Abilities Through The Use Of A Novel Problem Solving Task, Lisa Kay Lauderdale

Dissertations

Environmental enrichment is a key component to improving the psychological and physiological well being of animals in human care. Enrichment can be achieved through a variety of modalities, including the addition of objects and scents, or by providing the animals with additional challenges. The effectiveness of specific enrichment should be evaluated on a case-by-case basis to determine if the desired result is achieved. Environmental enrichment devices (EED’s) can be utilized to present novel problems to animals in human care. When confronted with a novel problem, dolphins can plan their behavior to create a more efficient strategy then previously modeled.

Replicability And Reproducibility In Comparative Psychology, Jeffrey R. Stevens

Jeffrey Stevens Publications

Psychology faces a replication crisis. The Reproducibility Project: Psychology sought to replicate the effects of 100 psychology studies. Though 97% of the original studies produced statistically significant results, only 36% of the replication studies did so (Open Science Collaboration, 2015). This inability to replicate previously published results, however, is not limited to psychology (Ioannidis, 2005). Replication projects in medicine (Prinz et al., 2011) and behavioral economics (Camerer et al., 2016) resulted in replication rates of 25 and 61%, respectively, and analyses in genetics (Munafò, 2009) and neuroscience (Button et al., 2013) question the validity of studies in those fields. Science, …

Reduction In Activity By Noxious Chemical Stimulation Is Ameliorated By Immersion In Analgesic Drugs In Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Waleed Al-Nuaimy, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Research has recently demonstrated that larval zebrafish show similar molecular responses to nociception to those of adults. Our study explored whether unprotected larval zebrafish exhibited altered behaviour after exposure to noxious chemicals and screened a range of analgesic drugs to determine their efficacy to reduce these responses. This approach aimed to validate larval zebrafish as a reliable replacement for adults as well as providing a high-throughput means of analysing behavioural responses. Zebrafish at 5 days postfertilization were exposed to known noxious stimuli: acetic acid (0.01%, 0.1% and 0.25%) and citric acid (0.1%, 1% and 5%). The behavioural response of each …

Was Jack The Ripper A Slaughterman? Human-Animal Violence And The World’S Most Infamous Serial Killer, Andrew Knight, Katherine D. Watson

Cruelty to Animals and Human Violence Collection

Hundreds of theories exist concerning the identity of “Jack the Ripper”. His propensity for anatomical dissection with a knife—and in particular the rapid location and removal of specific organs—led some to speculate that he must have been surgically trained. However, re-examination of a mortuary sketch of one of his victims has revealed several aspects of incisional technique highly inconsistent with professional surgical training. Related discrepancies are also apparent in the language used within the only letter from Jack considered to be probably authentic. The techniques he used to dispatch his victims and retrieve their organs were, however, highly consistent with …

Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson

Undergraduate Distinction Papers

Although giant pandas (Ailuropoda melanoleuca) are known to be solitary in the wild, cubs engage in frequent bouts of affiliative behavior in captive settings. The goal of the project was to investigate whether kinship or familiarity based on housing influenced the frequency of social interactions within one-year old giant panda cubs. Data were collected from June through mid-July 2016 at the Chengdu Research Base of Giant Panda Breeding, Sichuan, China. Over 113 hours of behavioral observations were recorded on four sets of twins and one singleton, focusing specifically on affiliative behaviors. Time housed together was a significant predictor of the …

Straight From The Horse's Mouth: An Examination Of Social Media Usage And Advertising Methodologies In The Sale Of Sporthorses, Michael Willham

Undergraduate Distinction Papers

This study discovered general market conditions as well as buyer and seller behavior in the sporthorse market for the disciplines of Dressage, Show Jumping, and Eventing. The efficient sale of sporthorses in these disciplines is equally as important of a consideration as the marketing and advertising decisions for any other product such as automobiles or electronics. Equids differ from regular products in that they typically have markedly higher inventory costs associated with the maintenance of holding onto a live animal. Therefore, it is arguably more imperative for businesses to determine the quickest and most efficient means to sell them. This …

Effects Of Pre-Conditioning On Behavior And Physiology Of Horses During A Standardised Learning Task, Kate Fenner, Holly Webb, Melissa Starling, Rafael Freire, Petra Buckley, Paul D. Mcgreevy

Animal Training and Obedience Collection

Rein tension is used to apply pressure to control both ridden and unridden horses. The pressure is delivered by equipment such as the bit, which may restrict voluntary movement and cause changes in behavior and physiology. Managing the effects of such pressure on arousal level and behavioral indicators will optimise horse learning outcomes. This study examined the effect of training horses to turn away from bit pressure on cardiac outcomes and behavior (including responsiveness) over the course of eight trials in a standardised learning task. The experimental procedure consisted of a resting phase, treatment/control phase, standardised learning trials requiring the …

P24. The Birds And The Beats: Perception Of A Beat In An Avian Model, Brendon Samuels

Western Research Forum

Background: Beat perception is a complex cognitive skill that enables humans to “feel” the beat in music, and is an essential component of synchronization of behavior and dance. The mechanisms in the human brain that facilitate beat perception are not entirely understood, and have only been studied thus far using non-invasive techniques. Some animals, such as songbirds, also seem to be able to detect a beat in rhythms, though this has never been formally tested independent of motor synchronization.

Methods: An operant experiment is used to assess if European starlings, a type of songbird, are capable of categorizing …

Human Head Orientation And Eye Visibility As Indicators Of Attention For Goats (Capra Hircus), Christian Nawroth, Alan G. Mcelligott

Social Cognition Collection

Animals domesticated for working closely with humans (e.g. dogs) have been shown to be remarkable in adjusting their behaviour to human attentional stance. However, there is little evidence for this form of information perception in species domesticated for production rather than companionship. We tested domestic ungulates (goats) for their ability to differentiate attentional states of humans. In the first experiment, we investigated the effect of body and head orientation of one human experimenter on approach behaviour by goats. Test subjects (N = 24) significantly changed their behaviour when the experimenter turned its back to the subjects, but did not take …
