The Pet’S ‘Perfect Bowl’: Environmental And Welfare Discourse In Alternative Pet Food Movements, Carly Baker

Theses and Dissertations--Geography

Marketing ‘sustainable and humane’ super-premium dog kibble has emerged alongside alternative food movements (AFM). Unfortunately, super-premium pet-food comprised of ‘high-quality’ protein is at odds with sustainability and affect for particular animals. This study analyzed social and geographical (mis)representations of nonhumans in the pet-food commodity chain by tracing how knowledge and value is produced, and mapping the geography of Open Farm dog food. I assess these geographies and discourses and I identify the following: (1) sustainability claims focus on transportation and packaging, ignoring the significant environmental and social impacts of animal agriculture. (2) Images of farmed animals on packaging often do …

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 …

Impact Of Early Life Stress And Cannabidiol On Behavior And Corticosterone Levels In Male And Female Rats, Marina Yacoub

Capstone Showcase

Organisms must maintain homeostasis that is regulated internally and externally. Fluctuation in homeostasis causes stress. Corticosterone, the main stress hormone in rodents, increases following exposure to acute stressors, such as being placed in a restrainer. However, early developmental experiences including maternal separation shape the development of the stress response into adulthood and impact the expression of depressive and anxiety-like behaviors. Many factors can shape the body's response to stress, for example, a rodent's previous exposure to a past stressor can affect their present behavior. Several studies have shown that female rats have lower or no changes in corticosterone levels compared …

Examining The Function Of Stone Wrapping Behavioral Pattern In Balinese Long-Tailed Macaques (Macaca Fascicularis), Patricia Mitchell

All Master's Theses

Long-tailed macaques (LTMs, Macaca fascicularis) have multiple stone handling (SH) patterns that vary in form and complexity across different populations, but little is known about the group of Balinese LTM’s motivation to wrap stones in the Monkey Forest of Ubud, Indonesia. This study focuses on whether the SH pattern, wrap (WRP), is an object play behavior with the potential of becoming a more functionally complex behavior (e.g., tool use). SH sequences were collected using all-occurrence and focal sampling and examined using the program Behavioral Observation Research Interactive Software (BORIS). In total, 322 minutes of footage were reviewed for both stones …

Finding Identity In The Intersections: Transnational Feminism And The Non-Human Primate, Kailyn Carr

Honors Theses

This project examines how the conversations among feminism and primatology offers a unique critical lens into how “man” dominates other identities, whether that be woman or non-human primate, specifically within the rigid colonial structures of Western society. Donna Haraway’s landmark post-humanist work joins these conversations, especially with her earlier work Primate Visions and Simians, Cyborgs, and Women. While Haraway has changed the narrative surrounding feminist theory within the biological sciences – what has now become recognized as feminist science and technology studies –, this shift in perspective continues to emphasize Western ideological practices and their attention to primatology. My …

Winner And Loser Effects In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Casey Mack

Honors Theses

Winner and loser effects have been documented in many species throughout the animal kingdom, but have yet to be investigated in Madagascar hissing cockroaches. This study seeks to determine if winner or loser effects are present in Madagascar hissing cockroaches. In Experiment 1, three subjects won a training contest and three subjects lost a training contest. Training contest winner and training contest loser subjects were then paired up in test contests. Four of the 6 subjects showed test contest outcomes consistent with their training contest outcomes, but the overall conclusions were ambiguous due to the small sample size. Whether the …

Conditioned Territory Defense In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Macy R. Albaitis

Honors Theses

In male blue gourami fish (Trichogaster trichopterus), signaled presentation of a male rival produces an aggressive conditioned response that results in an increased likelihood of the male winning the contest (Hollis, 1984). I replicated this classic study in a species that also shows territorial aggression: the Madagascar hissing cockroach (MHC; Gromphadorhina portentosa). During training, four adult male MHCs were designated as “CS+” animals and received a light (NS) followed by visual access to a rival male (US). Simultaneously, another group of four adult male MHCs designated as “UNC” animals received the light (NS) and visual access to a …

Activity Levels Of Bat Species At Interstate Highway Sites With And Without Wildlife Underpasses In The Washington Cascades, Jenna Chapman

All Master's Theses

Roads force wildlife to navigate degraded and fragmented habitats across the globe, creating barriers to movement and increasing the risk of mortality. This includes bats, whose movements between foraging and roosting habitats may be impeded by roads. Wildlife crossing structures (WCS) are a common mitigation strategy to increase connectivity, but investigation into bat activity in and around these structures is limited. I investigated bat species presence and activity along Interstate-90 in the Cascade Range of Washington State. My goal was to test whether all bat species found in the nearby forest were also active along the highway, and whether bat …

Career Development And Employability Skill Integration Within The Equine Science And Management Undergraduate Program At The University Of Kentucky, Savannah Faye Robin

Theses and Dissertations--Educational Leadership Studies

College graduates need to be equipped with career and employability skills that are necessary to be meaningfully and gainfully employed in their future. These skills consist of self-management, career-management, essential-employability, and discipline-specific skills. More responsibility is being placed on college and university academic programs to ensure that students are graduating with these skills when they enter the workforce. However, students are growing less likely to participate in out of course career development activities and resources. Integrating these skills into program curriculum can be an effective way to ensure that all students have the ability to develop these necessary skills.

While …

A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot

Graduate Theses, Dissertations, and Problem Reports (ETD)

Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …

Enhancing Stakeholder Engagement To Achieve The Sustainable Management Of Free-Roaming Equids, Celeste Carlisle, Dan Adams

Human–Wildlife Interactions

Wild horse (Equus caballus) and burro (E. asinus; WHB) stakeholders in the American West are divergent in their views of free-roaming equids on public lands. Management authority for free-roaming equids on designated public lands was given to the Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) in 1971 by U.S. Congress with the passing of the Wild and Free-Roaming Horses and Burros Act (WFRHBA). In 1976, the Federal Land Policy and Management Act (FLPMA) mandated the BLM to manage public lands for multiple-uses, which included livestock grazing, energy development, recreation, and timber harvest. …

Symbiotic Relationship Between Local People And Asiatic Black Bears, Jangchuk Gyeltshen

Human–Wildlife Interactions

There are 8 species of bears (Ursidae) in the world; of these, 6 species are known to occur in Asia. However, in Bhutan, there are only 2 species: the Asiatic black bear (Ursus thibetanus) and the sloth bear (Melursus ursinus). The Asiatic black bear is legally protected by the Forest and Nature Conservation Act of Bhutan 1995. The bear is categorized as vulnerable by the International Union for Conservation of Nature and also included under Appendix I of the Convention on International Trade in Endangered Species. Human–bear conflicts are prevalent in Bhutan, especially at the village …

Viral Injection Of Rna Polymerase Ii-Interacting Protein Rprd2 In The Nucleus Accumbens Induces Anxiety-Like Behavior In Mice, Hannah E. Woolard

Theses and Dissertations

Anxiety and its related disorders have become increasingly prevalent as more awareness and acceptance of mental illnesses have come to fruition, especially in the light of the ongoing COVID-19 pandemic. Anxiety can affect anyone regardless of their age, sex, or social status and is currently the most commonly diagnosed mental illness worldwide (Bandelow & Michaelis, 2015). While there are several effective treatments available, the underlying brain mechanisms that cause anxiety are still largely unknown and further research continues to piece together the complex pathophysiology behind this disease. The use of laboratory animal models, such as mice, to induce and observe …

Behavioral Differences In Urban Sciurus Carolinensis With Varying Human Exposure As A Model For Synanthropic Human-Animal Relationships, Tiffany M. Jordan

EWU Masters Thesis Collection

Synanthropic animals are considered a halfway point between wild and domestic animals that live in urban environments and depend on humans for their survival. Sciurus carolinensis, the eastern gray squirrel, symbolizes a distinctive coexistence between human and wildlife as they are commonly fed in parks and gardens. They are native to the eastern United States. Where they are invasive, they are found only in urban areas and not in rural or wildlife areas. This study examined how different levels of human exposure impact the behavior of S. carolinensis in its non-native range from two different perspectives by using flight initiation …

Motivated Science: What Humans Gain From Denying Animal Sentience, Uri Lifshin

Animal Sentience

Resistance to the idea that non-human animals are sentient resembles erstwhile resistance to the theory that the earth is not the centre of the universe, or that humans evolved from “apes”. All these notions are psychologically threatening. They can remind people of their own creatureliness and mortality and might make them feel guilty or uncertain about their way of life. An honest debate over animal sentience, welfare and rights should consider the human motivation to deprive animals of these things in the first place. I briefly review empirical evidence on the psychological function of denying animal minds.

Do Steller’S Jays Respond To Human Providers?, Jessica E. Guenther

Cal Poly Humboldt theses and projects

For millennia, humans and wildlife coevolved in a myriad of landscapes influencing each other through social interactions. Humans may be providing non-verbal signals in their facial features with gaze and head orientation that are perceived by non-human animals. The ability to follow human eye gaze and head orientation could enable non-human animals to access valuable resources, for example, birds provided with supplemental food. Few studies have quantified how closely birds in the wild watch and respond to ‘familiar’ humans who regularly provide food. From 2015-2019, Steller’s jays (Cyanocitta stelleri) in Arcata, California were fed shelled peanuts and observed …

Evaluation Of The Effect Of Culling On Browse Damage By The Japanese Serow In Gifu Prefecture, Japan, Shiori Ikushima, Naotoshi Kuninaga, Takashi Ikeda, Takuya Okamoto, Makoto Asano, Masatsugu Suzuki

Human–Wildlife Interactions

The Japanese serow (Capricornis crispus; serow) is a protected territorial ungulate native to Japan. However, locally overabundant serow populations can damage forest plantations and agriculture through browsing. Despite government permitted annual culling of serows on forest lands of Gifu Prefecture, Japan, browse damage continues to be reported in hinoki cypress (Chamaecyparis obtusa; cypress) plantations. Sika deer (Cervus nippon; deer), which are co-located with serows can also browse cypress, but their impacts have never been evaluated. The objective of our research was to evaluate the involvement of each species in browse damage and to establish …

Grizzly bear attractant policies in Montana: how regulations, recommendations, and resources differ among and between recovery areas

Chairperson or Co-Chairperson: Alexander L. Metcalf & Chad J. Bishop

Abstract

Grizzly bears (Ursus arctos horribilis) are a keystone species and play an important role in their environment. After near extinction, the U.S. Fish and Wildlife Service implemented a recovery plan of six recovery zones to increase grizzly populations. Although these efforts allowed grizzly bear numbers to increase, so too have human-grizzly bear conflicts, significantly challenging agencies in charge of bear management. A concern …

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 …
