The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr

Undergraduate Research Symposium

This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..

Training The Concept Of Innovate In Dolphins (Tursiops Truncatus) Is Both Creative And Cognitively Stimulating, Deirdre Yeater, Kathleen M. Dudzinski, Dawn Melzer, Andrew R. Magee, Michaela Robinett, Gonzalo Guerra, Kimberly Salazar, Terri Bolton, Heather Manitzas Hill

Psychology Faculty Publications

Creative or novel behaviors in bottlenose dolphins (Tursiops truncatus) can be indicators of flexible thinking and problem solving. Over 50 years ago, two rough-tooth dolphins demonstrated creative novel behaviors acquired through reinforcement training in human care. Since this novel training, a variety of species have been trained to respond to this conceptual cue. The current study assessed the creativity of 12 bottlenose dolphins (5 females, 7 males) housed at the Roatan Institute for Marine Sciences (RIMS) in Roatan, Honduras. Individual differences were found across four constructs measured for creativity: fluency, flexibility, elaboration, and originality. Variability in performance occurred across test …

Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti

Antioch University Full-Text Dissertations & Theses

Farmed animal sanctuaries provide lifelong care to formerly farmed animals. Many strive to educate their community about farmed animals and promote more compassionate lifestyles, such as veganism. Important to this is cultivating empathy and concern for the well-being of individual farmed animals. Essential to well-being is agency, which is the capacity of a living being to engage with their environments and to make choices for themselves. Farmed animals outside of sanctuaries have had their agency systematically suppressed and denied. Sanctuary educators can bring awareness to this and inspire alternative, agency-centered relationships with not only farmed animals but all living beings. …

A Year Of Wins For Farmed Animals, Lewis Bollard

General – Farm Animal Issues

Although the European Union shelved its ambitious farmed animal welfare reforms, there were other “wins” for farmed animals in 2023. There were 130 new corporate pledges to eliminate cages for laying hens and the worst abuses of broiler chickens. So far, over 1,000 corporate pledges have been fully implemented, and 39% of American hens, 60% of European hens, and 80% of British hens are cage-free, up from 6%, 41%, and 48%, respectively, a decade ago. The US Supreme Court upheld California’s Proposition 12, which bans the sale of eggs, pork, and veal from caged animals and their offspring in California. …

Fauna As Fieldworkers: An Analysis On The Use Of Animals As A Form Of Organic Weed And Pest Management In Modern Viticulture, Mariana Del Carmen Campano

Independent Study Project (ISP) Collection

Recent data on the current state of pesticide use in global agriculture suggests serious concerns over significant overuse and negative effects on both environmental and human health, and current trends only suggest continued increases in future global pesticide use. Without prompt, large-scale intervention, this global abuse of chemical pesticides spells significant threats of not only continued harm to global health and environmental quality, but also to the long term viability of agricultural lands and the growing threat of pesticide resistant insects and weeds. Various methods have been explored in the realm of integrated pest management (IPM), but a current lack …

Analyzing Human - Nonhuman Primate Conflict Mitigation Techniques In Mto Wa Mbu, Northern Tanzania, Lily Adams

Independent Study Project (ISP) Collection

Human – non-human primate conflict is particularly crucial due to primates’ high capacity to live among human populations. The study to analyze Human - Nonhuman Primate Conflict Mitigation Techniques, was carried in November 2023 at Mto wa Mbu, Northern Tanzania. To analyze techniques currently being used to mitigate human – non-human primate conflict, this study collected data through semi-structured interviews. Over 87% (n=35) of respondents used multiple mitigation techniques simultaneously. 80% of respondents (n=32) reported using projectiles to ward off foraging primates, 75% of respondents (n=30) reported using loud noises (made either by the voice/body or by manipulating noisemakers), 67.5% …

A Deeper Understanding Of Noise Effects On Cetaceans, Jason N. Bruck

Faculty Publications

Recent research with cetaceans under human care is illuminating just how dolphins are affected by human-made noise both in terms of their ability to cooperate as well as their ability to habituate to such noise. This research is providing granular detail to regulators assessing the problems associated with anthropogenic effects and is highlighting a role for behavior/cognition research in conservation.

A Quieter Ocean: Experimentally Derived Differences In Attentive Responses Of Tursiops Truncatus To Anthropogenic Noise Playbacks Before And During The Covid-19-Related Anthropause, Paige E. Stevens, Veda Allen, Jason N. Bruck

Faculty Publications

The effects of anthropogenic noise continue to threaten marine fauna, yet the impacts of human-produced sound on the broad aspects of cognition in marine mammals remain relatively understudied. The shutdown of non-essential activities due to the COVID-19-related anthropause created an opportunity to determine if reducing levels of oceanic anthropogenic noise on cetaceans affected processes of sensitization and habituation for common human-made sounds in an experimental setting. Dolphins at Dolphin Quest Bermuda were presented with three noises related to human activities (cruise ship, personal watercraft, and Navy low-frequency active sonar) both in 2018 and again during the anthropause in 2021 via …

Comparing U.S. Groups’ Openness To Pro-Animal Actions, Jo Anderson, Zach Wulderk

USA

As animal advocates know, an outreach tactic that is successful with one person will not necessarily be successful with all people. Advocates rarely launch campaigns with no idea of who will be seeing their ‘asks’ (i.e., requests for pro-animal actions). Even in the case of passive tactics such as billboards, advocates may know who frequents that part of the city. For example, they may be near a university, meaning their audience will include a high proportion of students. The United States public is diverse and groups of people can differ greatly in their opinions. Rather than taking a one-size-fits-all approach, …

Troop Composition And Behavior Of Mantled Howler Monkeys (Alouatta Palliata) In Mangroves And Forested Islands South Of David, Panama, Slate Hyacinthe

Independent Study Project (ISP) Collection

The mantled howler monkey, Alouatta palliata, is one of the most commonly studied and widely distributed primate species in Central America. They have been reported to inhabit mangrove environments in Panama, but few studies have undertaken to describe their demography and behavior in these particular ecosystems. For my study, I spent 12 days studying A. palliata populations in both the mangrove and forested island ecosystems (Isla Parida and Isla Boca Brava) south of David. Seven groups were found in the mangrove environments, and 11 groups were found on the island environments. The mangrove groups were significantly smaller and at a …

Spatial Ecology And Habitat Preference Of Yellow-Spotted Monitors (Varanus Panoptes) At Lizard Island National Park, Qld, Australia, Ryan Snyder

Independent Study Project (ISP) Collection

Lizard Island National Park is an area of strong habitat diversity, especially given its small size. There are several distinct habitats represented, including open sclerophyll woodlands, mangrove swamps, dune grasslands, foothills elevations, and of course anthropogenically modified human habitats. The object of this study was to observe the abundances and behaviors of the yellow-spotted monitor lizard (V. panoptes) in each of these habitat settings to answer the question of which habitat type is preferred amongst V. panoptes in the landscape context of Lizard Island National Park.

Study transects were conducted over the course of one month measuring abundance of V. …

A Survey Of Captive Wild And Exotic Animal Training Programs In The Eastern United States, Savannah Atchison

Senior Honors Theses

Methods of positive reinforcement as a successful means for animal training are the result of many years of research into operant conditioning and learning. However, current literature is unclear on the extent to which these methods are utilized in captive wild and exotic animal populations in the United States. Through phone interviews with animal trainers employed at zoos and wildlife rehabilitation centers in the eastern United States, the author determined that these facilities are currently utilizing positive reinforcement training methods which are proving to be a great benefit for all parties involved. They are enabling a variety of voluntary health …

Understanding Invasive Predation: Detections Of Feral Cats (Felis Catus) On Kangaroo Island’S Western River Refuge, Leah Boget

Independent Study Project (ISP) Collection

Feral cats (Felis catus) are a priority-level threat for small to medium-sized native vertebrates across Australia and especially so in insular environments like that of Kangaroo Island, South Australia. The island is home to several endangered and geographically restricted species, including the Kangaroo Island Dunnart (Sminthopsis aitkeni), an endangered marsupial endemic to Kangaroo Island. When bushfires spread across the island and burned x percent of native vegetation in late 2019 to early 2020, these populations were critically impacted and post-fire feral cat predation on the island risked their extinctions, motivating the creation of a refuge with …

Status Of Pangolins: A Case Study On "The Most Trafficked Mammal In The World" In Central-South Of Nepal, Tsogyal Wangmo Lama

Independent Study Project (ISP) Collection

Pangolins are subject to constant trafficking in Asia and increasingly in Africa for their meat and scales. Very little research is done on this species due to its nocturnal, burrowing, and elusive nature. The larger the size of an animal is, the better it is known to the people and vice versa. Hence all these eight species of pangolins despite being under the International Union for Conservation of Nature (IUCN) red list with the four Asian species declared endangered or critically endangered, are still illegally abused and used for ulterior motives due to a lack of awareness among the general …

Developing Novel Remote Camera Approaches To Assess And Monitor The Population Status Of Australian Sea Lions, Mathew Hourston, Daniela Waltrick, Stuart Blight, Ainslie Denham, Alex Hesp, Steve Taylor

Fisheries research reports

This project trialled the use of remote cameras to monitor the relative abundance of Australian sea lions (ASLs, Neophoca cinerea) at three Western Australian (WA) breeding colonies. The research was undertaken by the Department of Primary Industries and Regional Development (DPIRD) to assess whether the analysis of camera footage could be used to estimate ASL relative abundance, providing an alternative to the traditional “boots on the ground” approach (hereon in “BoG”) of visiting colonies to count animals. This report outlines the strengths and limitations of this novel approach rather than providing an update on the population status of ASLs. …

Chinese Consumers’ Attitudes Toward Animal Welfare: Behaviors, Beliefs, And Responses To Messaging, Jo Anderson

General - Animal Protection

Despite being comparatively neglected until recently, the suffering of animals in Asia is starting to command more attention from global animal advocacy activists. In particular, as the largest country in the world by both human and farmed animal population, and among the largest when measured by economy and land mass, China plays a central role here. However, the key question of how best to improve outcomes for farmed animals in China remains difficult to answer, due to the recency of the movement and a comparative lack of research on the topic.

Although China’s per capita meat consumption is lower than …

Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack

Faculty Publications

Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …

An Evaluation Of Ethograms Measuring Distinct Features Of Enrichment Use By Captive Chimpanzees (Pan Troglodytes), Julia L. Greeson, Kara I. Gabriel, John B. Mulcahy, Bonnie King Hendrickson, Susan D. Lonborg, Jay C. Holloway

Student Published Works

Environmental enrichment provides mental stimulation and minimizes abnormal behaviors in captive animals. In captive chimpanzees, individual animals may vary in the ways in which they benefit from enrichment or use enrichment devices, so investigating nuances in enrichment use may improve the welfare of captive chimpanzees. In the current study, three ethograms measuring distinct features of enrichment use (i.e., enrichment object, manipulation behavior, and social context) were evaluated by coding videos of captive chimpanzees (Pan troglodytes) at Chimpanzee Sanctuary Northwest in Cle Elum, WA. A total of 732 min and 58 s of video footage was coded from a larger video …

Is Chimpanzee (Pan Troglodytes) Wounding Frequency Affected By The Presence Versus Absence Of Visitors? A Multi-Institutional Study, Robin Elana Salak, Christina Cloutier Barbour

Student Published Works

Visitor effect studies have had inconsistent results, due in part to the inability to control for all confounding variables such as time of day, seasonal weather patterns, and so forth. This study represents the first instance where chimpanzee (Pan troglodytes) wounding frequencies were investigated across extensive time periods in the presence and complete absence of visitors, thus eliminating many visitor-related variables. Additional variables were eliminated through the zoo selection process, based on institutional responses to a 29-question survey, providing a novel approach to the question of visitor effects. The aim of this study was to determine if visitors …

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik

Faculty Publications

While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same …

Regaining Effort-Based Food Motivation: The Drug Methylphenidate Reverses The Depressive Effects Of Tetrabenazine In Female Rats, Deanna Pietrorazio

Honors Scholar Theses

Tetrabenazine (TBZ), a vesicular monoamine transporter type 2 (VMAT-2) inhibitor, depletes dopamine and induces motivational deficits and other depressive symptoms in humans. Methylphenidate (MPH) is a dopamine transport blocker that is used to enhance motivational function. Previous studies have shown that in male rats, TBZ induces a shift in effort-related choice such that a low-effort bias is induced. In male rats this occurs at a dose range of 0.75-1.0 mg/kg TBZ, and this effect is reversible with co-administration of MPH. Recent studies have shown that females need a higher dose of TBZ (2.0 mg/kg) to show the low-effort bias. The …

Buprenorphine Effects On Anxiety-Like Behavior In B6 Mice, Megan K. Thibert

Select or Award-Winning Individual Scholarship

Buprenorphine, a semi-synthetic opioid prescribed for the treatment of opioid use disorder (OUD), has been suggested as a potential pharmacological treatment for anxiety. Some preclinical and clinical studies provide support for the anxiolytic effects of buprenorphine, but research in this area is scarce, and findings to date have been mixed. The present study was designed to test the hypothesis that buprenorphine alters anxiety-like behavior in C57BL/IJ (B6) mice measured using the elevated zero maze (EZM). Adult, male mice (n=10) were given subcutaneous injections of saline (control) and three doses of buprenorphine (0.3, 1, and 10 mg/kg). One hour following injection, …

Independent Study Project (ISP) Collection

This study investigated the infant-directed behaviors of adult male and female olive baboons in Randilen Wildlife Management Area in April of 2022. The objectives were 1) To determine the difference between olive baboon males and females in frequency and duration of listed behaviors towards infants; 2) To classify the interactions of adult male and adult female olive baboons with infants as either primarily affiliative or primarily aggressive; 3) To determine the frequency of selected behaviors at different reproductive phases (lactation, estrus, neutral, indeterminant) amongst female olive baboons towards infants. A single baboon troop in Randilen Wildlife Management Area was observed …

Spatiotemporal Relationships Of Coyotes And Free-Ranging Domestic Cats As Indicators Of Conflict In Culver City, California, Rebecca N. Davenport, Melinda Weaver, Katherine C. B. Weiss, Eric G. Strauss

Center for Urban Resilience Scholarship

As habitat generalists, urban coyote (Canis latrans) populations often utilize an abundance of diverse food sources in cities. Within southern California, domestic cats (Felis catus) comprise a higher proportion of coyote diets than in other studied urban areas throughout the United States. However, it is unclear which ecological factors contribute to higher rates of cat depredation by coyotes in this region. While previous research suggests that coyote presence may have a negative effect on free-ranging domestic cat distributions, few studies have determined whether urban green spaces affect coyote or free-ranging domestic cat occurrence and activity within …

Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck

Faculty Publications

Cetaceans are potentially at risk of poor welfare due to the animals’ natural reliance on sound and the persistent nature of anthropogenic noise, especially in the wild. Industrial, commercial, and recreational human activity has expanded across the seas, resulting in a propagation of sound with varying frequency characteristics. In many countries, current regulations are based on the potential to induce hearing loss; however, a more nuanced approach is needed when shaping regulations, due to other non-hearing loss effects including activation of the stress response, acoustic masking, frequency shifts, alterations in behavior, and decreased foraging. Cetaceans in managedcare settings share the …

Man V.S. Wild: An Analysis Of Language Used Regarding Human-Wildlife Conflict In The Kibale National Park Community, Western Region, Uganda, Sophie Perfetto

Independent Study Project (ISP) Collection

If humans are to live sustainably and in harmony with wildlife in the vicinity of Protected Areas, policy makers, and government authorities need to make informed decisions with consideration to the needs of local communities. For this to happen, policy makers must understand the perceptions of local communities and take local perspectives into account. As language is at the root of perception, language was studied in the context of its role in shaping local perceptions of human-wildlife conflict and consequential conflict mitigation strategies. Six communities around the Northern region of Kibale National Park, Uganda, were studied, with sites located in …
