Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales

Human–Wildlife Interactions

Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …

The Philosopher's Journey: A Chapter In Kindness And Animals, Vaughn E. Sayers

UNF Undergraduate Capstone Projects and Honors Theses

We each are presented with a choice; do we remain in the cave of ignorance or embark on the philosopher’s journey. Your choice will determine the way in which you interpret this paper. However, I will confidently make the assumption that you, like myself, desire to embrace an existence guided by the light of wisdom. This thesis is one of many chapters in the philosopher’s journey, dealing with animals and (cutting through the jargon) kindness. I have found that a lot of scholarship on animal ethics acknowledges a truth, but does not acknowledge that the application of such a truth …

Reconciling Just Preservation, Shelley M. Alexander

Animal Sentience

Treves et al.’s target article can play an important role in reconciling the needs of future generations and non-human animals in conservation. Human capacities are adequate for interpreting and defining many non-human animal needs. Worldviews are more complex, however, and conservation science, like the target article itself, suffers from a lack of diversity and inclusiveness. This may pose practical impediments to realizing just preservation.

Sheep Are Sentient, But Not Identical, Alison Hanlon

Animal Sentience

Marino & Merskin (M&M) provide a timely reminder that sheep have advanced cognitive abilities, but do we still have to provide evidence to justify animal sentience? In the EU, regulations are designed to support farm animal welfare. Whilst the regulations are imperfect, they do emphasize behavioural needs and other concepts relevant to sentience. The persistence of sheep welfare issues such as lamb mortality indicates that regulations may not be achieving their desired goal. We can quibble about the science described by M&M yet reach the same conclusion: sheep (lambs, ewes and rams) are not all identical, but they are all …

Why Factual Appeals About The Abilities Of Sheep May Fail, Sarah Gradidge, Magdalena Zawisza

Animal Sentience

Marino & Merskin (2019) express hope that providing people with positive information about the abilities of sheep (factual appeals) will improve perceptions of them and thus improve their welfare. However, these factual appeals can, and do, fail to change perceptions of animals. This commentary considers why and when factual appeals fail, and with whom they may be effective.

Our Disparaging View Of Sheep Is Indeed Based On Cognitive Inadequacy: Unfortunately, It’S Ours, Hank Davis

Animal Sentience

Additional data, such as those surveyed by Marino & Merskin, are unlikely to change our perception of sheep. Arguably, the problem lies deeper than insufficient information. There are indeed cognitive deficits at the core of the problem, but they reside in Homo sapiens, not sheep. Judgmental biases that originated in the Pleistocene age have been over-extended in the modern world and result in unreasoning discriminative practices including speciesism. “Ism’s” run deep and the more an “other” looks and acts like us, the more respect we give it. Sheep do not prosper as “individual sentient beings” under such a heuristic.

Social Cognition In Sheep: Welfare Implications, Keith M. Kendrick

Animal Sentience

More research has been carried out on social cognition in sheep than in other farm animal species. Although this has often been featured widely in the media, there is still limited public awareness of it. Marino & Merskin’s review is therefore both important and timely. In my commentary, I focus primarily on what has been established about the complexity of sheep social cognition, at the level of both brain and behavior, and on some of these findings for sheep welfare.

Anthropocentrism: Practical Remedies Needed, Helen Kopnina

Animal Sentience

It is true that one of the harmful consequences of creating categories where one group is unique and superior to others is that it justifies discriminating against the inferior groups. And outright abuse of nonhuman animals is indeed morally unjustifiable. But what is to be done about it?

On The Brink Of Extinction: The Fate Of The Pacific Northwest's Southern Resident Killer Whales, Sabrina Wilk

Pomona Senior Theses

The killer whales that roam the northeastern Pacific Ocean have been the objects of studies since the 1970s, making them the most well-studied population of orcas in the world. Three distinct ecotypes of killer whales (Orcinus orca), known as residents, transients, and offshores, share these waters. The ecotypes are morphologically and behaviorally distinct to the extent that some scientists consider them separate species, with residents eating salmon, transients specializing on marine mammals, and offshores preferring Pacific sleeper sharks and Pacific halibut. Resident populations have endeared themselves to the region's locals with their striking black and white markings and …

A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam

Animal Sentience

Marino & Merskin’s review sheds light on the complexity of the mind, learning, and cognition of sheep. Readily observable behavior has value in its own right for promoting the well-being of animals. A behavior-analytic approach can add substantially to the understanding of sheep as individuals as well as their learning capacities. The findings can also be applied to arranging their environments to promote their well-being as well as behavioral change in those responsible for their care and management.

The Intrinsic Value Of Nature, Joanna E. Lambert

Animal Sentience

Treves et al. explain the need to preserve the rights of nonhuman species, human youth, and future generations. Although conservation biology has claimed to have an intrinsic valuation ethic since its inception in the 1980s, many aspects of the field have taken a decidedly anthropocentric and instrumentalist trajectory. This has important consequences for conservation-related policy and practice at all scales: local, regional, and global.

Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff

Animal Sentience

Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.

Human And Nonhuman Animals: Towards Equality, Catherine Price

Animal Sentience

Chapman & Huffman argue that we should not consider humans as unique and superior to nonhuman animals. Ecofeminism advocates the respectful treatment of humans, nonhuman animals, and the environment.

The Legitimation & Networked Unification Of #Nodapl: Diverse Discourses Of Value Validate A Collective Identity, Jacqueline Marie Ouellette

Theses and Dissertations (Comprehensive)

NoDAPL was, first and foremost, an Indigenous-led resistance against the construction of a pipeline in North Dakota. It was also a movement that built solidarity, bridging networks between international Indigenous peoples, Black Lives Matter activists, veterans, and feminists. This discourse analysis of social media and digital texts addresses the networked publics, collective identities, social capital, and intersectionality in applying Van Leeuwen’s (2007) understanding of legitimation. In doing so, the practice of reproducing and extending the values, themes, and images of various algorithmic imaginaries will be explored, as they relate to network homophily, identity construction, and mobilization. This study will argue …

Measuring Glutamate And Oxygen In Brain Reward Circuits In Animal Models Of Cocaine Abuse And Decision-Making, Seth Richard Batten

Theses and Dissertations--Psychology

Drug-specific reward and associated effects on neural signaling are often studied between subjects, where one group self-administers drug and a separate group self-administers a natural reinforcer. However, exposure to drugs of abuse can cause long-term neural adaptations that can affect how an organism responds to drug reward, natural reward, and their reward-associated stimuli. Thus, to isolate drug-specific effects it is important to use models that expose the same organism to all of the aforementioned. Multiple schedules provide a means of dissociating the rewarding effects of a drug from the rewarding effects of food within a single animal. Further, drug users …

Effects Of A Voluntourism Experience On Perceptions And Attitudes Toward Environmental Sustainability And Science, Mireille Gonzalez

All Master's Theses

The current study explored the impact of a volunteer tourism experience at a community-based conservation (CBC) organization on volunteer perceptions, attitudes, and values toward conservation, the environment, and science. The Madagascar Research and Conservation Institute (MRCI) is a CBC organization that utilizes volunteers as a data collection resource and workforce for conservation and community outreach initiatives. The current study analyzed data from volunteer experience evaluations (VEE), which included pre- and post-experience self-report surveys comprised of qualitative and quantitative response sections, completed by 45 voluntourists over a three-month span. The quantitative findings indicate that the voluntourist experience improved participants’ self-reported attitudes …

How Researchers Address Ethical Concerns Regarding Habituating Nonhuman Primates: Results Of A Survey And Suggestions For Future Practice, Victoria M. Green

All Master's Theses

In this study, I analyzed primatologists’ perceptions regarding the habituation of wild nonhuman primates. I distributed an online survey to primatologists and received 406 responses, 286 of which were used in data analysis. I used two sets of six-scale Likert scoring questions to determine respondents’ perceived ethical concerns and ethical duties. Exploratory factor analysis of 11 items revealed three factors regarding ethical concern, including concerns for the indirect harms of habituation (M = 5.03; SD = 0.89), unhabituated behavior after habituation is established (M = 4.98; SD = 1.08), and harms during habituation (M = 3.94; SD …

Psychologists' Use Of Dogs In Psychotherapy: A Therapeutic Exploration, Christine A. Treece

Antioch University Dissertations & Theses

The current fund of literature documents the many benefits of using dogs as adjunct healing agents for both physical and psychological ailments. Despite the ever-growing body of research about dogs as adjunct interventions, there is a meager amount of information available about clinician’s experience of bringing their dogs to work with them. This dissertation is an in-depth exploration of six psychologists licensed in the state of Washington who brought their dogs with them to work. Each participant’s interview was analyzed using Interpretative Phenomenological Analysis. From their interviews, nine primary themes were identified: Reason for the Acquisition of Dog, Nature of …

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Antioch University Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …

Battle Of The Sexes In Best Of Breed: Sex Influences Dogs’ Success In The Show Ring, Bethany J. Wilson, Alicia J. Kasbarian, Navneet Dhand, Paul D. Mcgreevy

Competitive Breed Shows Collection

Much of the research on pedigree dog breeding has been directed towards understanding the implications of reduced genetic diversity and the prevalence of inherited disorders. An example is the potential role of the popular sire effect in perpetuating genetic defects. If male dogs are more likely than bitches to be identified as examples of members of a breed that align with breed standard, they may be selected for breeding earlier. This may contribute to the influence of individual males and contribute to popular sire effect. Conversely, if breed standards are written in a sex-neutral fashion, and if dogs are entered, …

Management Of Cull Dairy Cows—Consensus Of An Expert Consultation In Canada, Jane Stojkov, G. Bowers, M. Draper, Todd Duffield, P. Duivenvoorden, M. Groleau, Deb Haupstein, R. Peters, Jane Pritchard, C. Radom, N. Sillett, W. Skippon, H. Trépanier, David Fraser

Farm Animal Welfare Collection

Many cull dairy cows enter the marketing system and travel to widely dispersed and specialized slaughter plants, and they may experience multiple handling events (e.g., loading, unloading, mixing), change of ownership among dealers, and feed and water deprivation during transport and at livestock markets. The objectives of this study were to describe the diverse management of cull dairy cows in Canada and establish consensus on ways to achieve improvements. A 2-day expert consultation meeting was convened, involving farmers, veterinarians, regulators, and experts in animal transport, livestock auction, and slaughter. The 15 participants, recruited from across Canada, discussed regional management practices …

Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes

Senior Honors Theses

African Wild Dogs (Lycaon pictus) are an endangered species of canid from Sub-Saharan Africa. They are very social communal hunters, and are capable of chasing down prey for long stretches of time. Wild dogs benefit a savannah ecosystem by regulating the populations of their prey so that it does not become unhealthy and overgrown. Like many organisms, wild dogs are also in competition with other predators for resources, namely lions and hyenas, who are capable of stealing their kills and occasionally injuring and killing them. Due to the depletion of their wild prey, wild dogs may also prey …

Optimizing Methods To Determine Metabolizable Energy Values Of Feed Ingredients For Broilers, Skyler P. West

Graduate Theses and Dissertations

Determination of metabolizable energy (ME) and amino acid (AA) digestibility values of single feed indigents continues to be two of the most important aspects for successful least-cost poultry feed formulation. It would be advantageous if a common diet type could be utilized to determine both ME and AA digestibility values of feed ingredients within a single assay. Two experiments were conducted to evaluate the effect of basal diet type and excreta collection method on the ME value of single feed ingredients determined in broiler chicks using the regression method. In experiment 1, the objective was to investigate the influence of …

A Role For Epac1 And Epac2 In Nociceptor Hyperexcitability And Chronic Pain After Spinal Cord Injury, Samantha Berkey

Dissertations and Theses (Open Access)

Chronic pain is a major complaint of those living with spinal cord injury (SCI), affecting 65-80% of the SCI population, but the treatment options remain limited or non-existent. The cAMP sensor EPAC has previously been shown to play a key role in chronic inflammatory and neuropathic pain, though the contribution from each of its two main isoforms, EPAC1 and EPAC2, is unclear. Here I test the hypothesis that both EPAC1 and EPAC2 play a key role in the maintenance of persistent nociceptor hyperexcitability and chronic pain after SCI.

Using both a T9 SCI mouse model and a T10 SCI rat …

Responsiveness Of Cobb Mv × 700 Broilers To Dietary Amino Acid And Energy Density, Craig William Maynard

Graduate Theses and Dissertations

As new broiler crosses are introduced to the industry, it is of paramount importance to understand their nutritional digressions from previous and other modern broilers. In particular, amino acids (AA) and dietary energy have been identified as key drivers of live performance and carcass composition. In addition, increased nutrient density in broiler diets have been linked to an increase in breast muscle myopathies such as white striping and woody breast. Therefore, a series of trials were conducted to determine the responsiveness of live performance, carcass characteristics, and breast muscle myopathies of Cobb MV × 700 broilers to dietary AA and …

Portraits With A Posthumous Voice: Reinforcing And Contesting Social Norms In The Heterotopic Museum And Cemetery, Matthew J. Crissey

Museum Studies Theses

Abstract

The following paper qualitatively analyzes and documents over 500 memorial-photographs/etched portraits on tombstones in ten Western New York cemeteries. This paper covers fourteen topics, ranging from religion to gang-violence. A juxtaposition of portraits exhibited within the Smithsonian National Portrait Gallery with memorial-portraits on tombstones revealed heterotopic environments creating a public forum enabling the reinforcing or contestation of social ideologies. In other words, the author observed the similarities of identities and social norms publicly expressed on tombstones and gallery portraits.

A Social Constructionist approach enabled the study to examine how one social phenomenon contributes to the shaping of a culture. …

The Effect Of Rem Sleep Deprivation On Spatial Memory In Male And Female Rats, Kaitlyn Heywood

Seton Hall University Dissertations and Theses (ETDs)

It is important for an organism to excel in spatial memory abilities. An organism’s survival is dependent on their ability to navigate through their environment to find resources, such as food and water, while being able to navigate home safely. With how important it is to navigate an environment safely, it is important to investigate things that impact spatial memory, such as rapid eye movement (REM) sleep deprivation. Sleep research has primarily utilized male rodents to model sleep disturbances studies which cannot be easily studied in human participants. Research has been divided on whether four hours of REM sleep deprivation …

Prevailing Clusters Of Canine Behavioural Traits In Historical Us Demand For Dog Breeds (1926–2005), Bethany Wilson, James Serpell, Harold Herzog, Paul Mcgreevy

Demography and Statistics for Companion Animal Populations Collection

Drawing on American Kennel Club (AKC) puppy registration numbers for approximately 82 varieties of pedigree dogs between 1926 and 2005, the current article analyses behavioural reports on 32,005 dogs of these varieties reported through the Canine Behavioural Assessment and Research Questionnaire (C-BARQ). Cluster analysis of C-BARQ scores indicates that the 82 breeds fell into six clusters. Average scores for each of the 14 behavioural subscales and 22 miscellaneous traits in C-BARQ were calculated for each cluster, and the breeds in each cluster with average scores most similar to the cluster averages were selected as titular breeds. Titular breeds for each …

Diffusion Through The Ex Vivo Vitreal Body – Bovine, Porcine, And Ovine Models Are Poor Surrogates For The Human Vitreous, Sara Shafaie, Victoria Hutter, Marc B. Brown, Michael T. Cook, David Y.S. Chau

Pharmacology and Animal Models in Research Collection

The human vitreous humour is a complex gel structure whose composition and physical properties can vary considerably from person to person and also change with age. To date, the viscoelastic properties of the human vitreous gel has not been thoroughly investigated and despite many years of intensive research, an ideal vitreous substitute remains a challenge. Understanding the physical structure and properties of the vitreous is of fundamental and therapeutic interest, providing a clear insight into diffusion and transport of administered ophthalmic drug molecules into the vitreous. A number of mammalian surrogates, mainly bovine, porcine and ovine vitreous humours have been …

Integrating Multiple Genetic Detection Methods To Estimate Population Density Of Social And Territorial Carnivores, Sean M. Murphy, Ben C. Augustine, Jennifer R. Adams, Lisette P. Waits, John J. Cox

Forestry and Natural Resources Faculty Publications

Spatial capture–recapture models can produce unbiased estimates of population density, but sparse detection data often plague studies of social and territorial carnivores. Integrating multiple types of detection data can improve estimation of the spatial scale parameter (σ), activity center locations, and density. Noninvasive genetic sampling is effective for detecting carnivores, but social structure and territoriality could cause differential detectability among population cohorts for different detection methods. Using three observation models, we evaluated the integration of genetic detection data from noninvasive hair and scat sampling of the social and territorial coyote (Canis latrans). Although precision of estimated density was …
