Living Among Wildlife: Elevating Human-Wildlife Interactions And Coexistence, Bridget Rebecca Murphy

Graduate Student Portfolios, Professional Papers, and Capstone Projects

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

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. …

Classification Of Large Scale Fish Dataset By Deep Neural Networks, Priyanka Adapa

Electronic Theses, Projects, and Dissertations

The development of robust and efficient fish classification systems has become essential to preventing the rapid depletion of aquatic resources and building conservation strategies. A deep learning approach is proposed here for the automated classification of fish species from underwater images. The proposed methodology leverages state-of-the-art deep neural networks by applying the compact convolutional transformer (CCT) architecture, which is famous for faster training and lower computational cost. In CCT, data augmentation techniques are employed to enhance the variability of the training data, reducing overfitting and improving generalization. The preliminary outcomes of our proposed method demonstrate a promising accuracy level of …

Does Social Organization, Litter Size, Sexual Dimorphism, And Phylogeny Influence Multiple Paternity In Mammals?, Madison Roberts

Honors Theses

Animal social systems are complex and the dynamics of one component could influence the dynamics of another. The aim of this literature search research was to determine the interrelatedness between mammalian social organization and mating system, two components of social systems. The mating system was represented by multiple paternity, the number of litters with more than one father, as genetic analysis tells which individuals reproduced with who. Variables that might influence multiple paternity amongst extant mammalian species included in this study are variable social organization, male social organization, mean litter size, sexual dimorphism, and phylogenetics. Analysis was conducted using 56 …

Using A Toxic Aging Coin To Assess Hexavalent Chromium-Induced Neurotoxicity., Samuel Thomas Vielee

Electronic Theses and Dissertations

We are facing an aging crisis, with 20% of the U.S. population projected to be geriatric (65+) by 2030 and live another 40+ years. Age-related diseases accompany a growing geriatric population, emphasizing the need to understand their etiology. Environmental pollutants compound this crisis by: 1) geriatrics are more susceptible, exacerbating age-related diseases and comorbidities, and 2) they accelerate biological aging, inducing age-related diseases at younger ages. We address this crisis using a ‘toxic aging coin’ approach; heads examines how age impacts toxicity, tails examines how chemicals accelerate aging. This thesis applies the heads side for Cr(VI)-induced neurotoxicity across ages. We …

Repeated Treatment With 5-Ht1a And 5-Ht1b Receptor Agonists: Evidence Of Tolerance And Behavioral Sensitization, Jordan Taylor

Electronic Theses, Projects, and Dissertations

Serotonin has been found to regulate several cognitive and physiological functions, and its role in depression and other neuropsychiatric disorders has been a focus of research. More specifically, a wealth of research regarding serotonin focuses on serotonergic medications in the treatment of neuropsychiatric disorders, such as depression and anxiety, and stimulates the 5-HT_1A and 5-HT_1B receptors. Within the last decade, there has been an increase in prescriptions of psychotropic medication for children, however, the efficacy and adverse effects of these drugs have not been evaluated in younger populations. While antidepressants reduce symptoms of depression in adults, they are …

1-Methyl-4-Phenyl-1,2,3,6-Tetrahydropyridine (Mptp)-Treated Adult Zebrafish As A Model For Parkinson’S Disease, Emmeline Bagwell

All Theses

The use of adult zebrafish, Danio rerio, as a model for human neurodegenerative diseases has proven valuable in pharmaceutical development and genetic disease research due to their high genetic homology to humans, cost-effective husbandry, and quick life cycle breeding times. Despite their promise, most zebrafish research has focused on embryonic stage organisms, primarily due to the ease of direct handling protocols and rapid progression through developmental stages. Recognizing the limitations of early-stage organisms in modeling adult diseases, recent efforts have shifted the applicability of zebrafish models, particularly for Parkinson's Disease, due to the nature of the disease impacting patients 55 …

Habitat Associations Of Plains Spotted Skunk (Spilogale Interrupta) Across The Plains Ecoregion. And The Landcover Occupancy Models Of The Gray Fox (Urocyon Cinereoargenteus) In The Southeastern Plains Region In Arkansas, Michael Shaw

Graduate Theses and Dissertations

Much of the landscape of the United States has been altered by humans, leading to the eradication of most populations of large mammalian predators. Consequently, many species of mammalian mesopredators (medium-sized mammalian predators) have come to dominate the landscape. Species such as the gray fox (Urocyon cinereoargenteus) may appear to be on the rise and doing well due to their widespread range, but at a local scale may need monitoring and less is known in areas of its range. Others such as the plains spotted skunk have a wide range across the plains but are on the decline even with …

Demographics, Sexual Dimorphism, And Ecological Aspects Of Ambystoma Annulatum (Ringed Salamander) In Northwest Arkansas, Usa, Brian M. Becker

Graduate Theses and Dissertations

The need to study and monitor amphibian populations is increasing along with the threats to their population stability and persistence in nature. Northwest Arkansas is one of the fastest growing areas in the nation and with that growth comes rapid changes in land use, massive alterations to habitats, habitat loss, and the introduction of nonnative plants and animals. Ambystoma annulatum (Ringed Salamander) is an Ambystomatid endemic to the Ozark and Ouachita Mountains of southern Missouri, northern and western Arkansas, and eastern Oklahoma giving it a relatively small distribution compared to most Ambystoma. Therefore, Arkansas constitutes a significant portion of the …

Why Humans Kill Animals And Why We Cannot Avoid It, Benjamin L. Allen, Christopher Bobier, Stuart J. Dawson, Peter J S Fleming, Jordan Hampton, David Jachowski, Graham I H Kerley, John D. Linnell, Kelly Marnewick, Liaan Minnie, Mike Muthersbaugh, M Justin O'Riain, Dan Parker, Gilbert Proulx, Michael J. Somers, Keifer Titus

Animal production and livestock research articles

Killing animals has been a ubiquitous human behaviour throughout history, yet it is becoming increasingly controversial and criticised in some parts of contemporary human society. Here we review 10 primary reasons why humans kill animals, discuss the necessity (or not) of these forms of killing, and describe the global ecological context for human killing of animals. Humans historically and currently kill animals either directly or indirectly for the following reasons: (1) wild harvest or food acquisition, (2) human health and safety, (3) agriculture and aquaculture, (4) urbanisation and industrialisation, (5) invasive, overabundant or nuisance wildlife control, (6) threatened species conservation …

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% …

Creating A Framework For An Effective Koala Recovery Center: A Case Study Of Friends Of The Koala, Nsw, Finley Scoular

Independent Study Project (ISP) Collection

Koala populations in New South Wales, Queensland, and the Australian Capital District are currently faced with factors that threaten their survival. Within one decade, their status has shifted from stable to vulnerable to endangered. The cause of this is attributed to increased exposure to dog attacks, vehicle collisions, diseases, and habitat fragmentation and destruction. The koalas' status of endangered in these territories has illuminated the need for human intervention. This study focuses on the specific form of human intervention that involves the rescue, rehabilitation, and release of wild koalas. Due to the recent koala status change from vulnerable to endangered, …

Við Pollurinn: The Effects Of Human-Caused Stimuli On Harbor Seals (Phoca Vitulina) In Ísafjörður, Ella Jorgensen

Independent Study Project (ISP) Collection

Harbor seals are important for the health of Iceland’s marine ecosystems. They are normally seen hauled-out onto land to rest. There are many factors that affect the haul-out patterns of harbor seals including location, season, time of day, tide height, weather, and human-caused stimuli. The presence of human-caused stimuli can also have a negative impact on haul-out patterns and behaviors. The Icelandic harbor seal population is threatened as it has been declining since 1980. Climate change and the rise of tourism in Iceland may be a factor contributing to this decline; and there is a gap in knowledge on the …

Investigating Monodelphis Domestica As An Alternative To The Mus Musculus As An Animal Model, Cristian M. Botello, John L. Vandeberg, Mario Gil

Research Symposium

Background: Mus Musculus is one of the first and one of the most widely used animal models in current neuroscience literature (Phifer-Riley & Nachmann, 2015). However, the research community needs alternatives to rodent models to study the mammalian brain. Research is needed to see if antibodies that target tyrosine hydroxylase, which are well researched in mice, can also be used to study the Monodelphis domestica brain.

Methods: Following transcardial perfusions and brain extractions, mouse and opossum brains were processed and stained for tyrosine hydroxylase (and with Nissl). Opossum brains will then be sliced and processed using IHC methods to compare …

The Implications Of Solidarity For Food Ethics, John Sniegocki

The Journal of Social Encounters

This essay examines numerous ways in which commitments to solidarity have relevance in the area of food ethics. Among the topics explored are food insecurity and hunger, workers’ rights, ecology, and the treatment of animals. Particular attention is paid to the impacts of the production and consumption of animal products. These issues are examined through the lens of the developing understanding of solidarity present in the tradition of Catholic social teaching (CST). The ethical framework provided by CST, it is suggested, could be further enhanced by insights drawn from the growing tradition of “Black veganism” and its holistic, intersectional understanding …

Impact Of Covid-19 On Service Dog Organizations, Danny Benbassat, Abigail Konopasky, Michael Fox

People and Animals: The International Journal of Research and Practice

The 2019 coronavirus pandemic led to federal, state, and local measures that paralyzed businesses across the nation. Among them were behavioral and mental health nonprofit organizations. The purpose of this study was to understand the impact of the pandemic on nonprofit programs that train and place service dogs with veterans/service members. Six service dog managers completed eight reflection probe questionnaires and participated in three focus groups. This study found that facility shutdown, businesses shutdown, and social distancing resulted in a training bottleneck for both canines and humans. These primary challenges created secondary and tertiary challenges that mirror and lend support …
