Effects Of Failure On Subsequent Performance In The Bottlenose Dolphin (Tursiops Truncatus), Lisa Kay Lauderdale
Master's Theses
The current study examined the immediate effects of two types of failure during operant-conditioning based training sessions in 11 bottlenose dolphins (Tursiops truncatus) at the U.S. Navy Marine Mammal Program in San Diego, CA. While learning a multi-faceted behavior not commonly found in nature, such as beaching, animals are likely to perform approximations of the behavior that are not successful and do not result in reinforcement. The effects of failure on beaching trials were systematically investigated over a three-month period by determining the mean failure rate and the probability of success after initial success, initial attempts, and initial …

Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, Megan S. Broadway
Master's Theses
The study of canine cognition can be useful in understanding the ontology and selective pressures that affect the development of cognitive abilities. Dogs have undergone intensive artificial selection yielding distinctive breeds which differ both phenotypically and behaviorally. Breed based cognitive differences have not been found but some studies suggest there may be differences in broader categories such as working disposition and sex. The influence of size on canine cognition has not been thoroughly addressed despite the fact that large dogs are often perceived to be ‘smarter’ than small dogs. This preconception has only recently been addressed and supported in one …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry
Master's Theses
This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …

Towards A Framework For Reproductive Violence”, Caitlyn Kelty-Huber
All Student Scholarship
Since the inception of ecofeminist discourse in the 1970’s, ecofeminists and feminists alike have been divided on their stances toward the ethics of consuming the bodies and by-products of other animals. A powerful cohort of ecofeminists, in part comprised by such scholars as Marti Kheel, Lori Gruen, Greta Gaard, and Carol J. Adams, have done a tremendous amount of work to situate a concern for more-than-human animals within ecofeminism and beyond. Unfortunately, as Cusack highlights, feminism’s failure to both recognize the parallel oppression of “dairy” cows and female farmed animals, and to thoughtfully incorporate that knowledge into feminist praxis has …

Responses Of Two Strains Of Broilers To Diets Varying In Essential Amino Acid Density And Energy Levels, Tyler James Clark
Graduate Theses and Dissertations
The responses of two different commercial strains of broilers to diets varying in overall amino acid levels and metabolizable energy levels were observed. Amino acid levels used were 80%, 90%, 100%, 110%, 120%, and 130% of Ross recommended minimum digestable levels of essential amino acids. Energy levels used were either below or above Ross recommended metabolizable energy levels. Diets were fed for 56 days. The two strains were a fast growing broiler strain and a slower growing broiler strain. A selection of birds from each pen was processed at 35, 43, and 56 days of age. Average body weights, cumulative …

The Abundance And Distribution Of Mallards In The Lower Mississippi Alluvial Valley Of Arkansas, John Andrew Herbert
Graduate Theses and Dissertations
The management of wintering waterfowl in North America requires flexibility because of constantly changing landscapes and conditions. Many mallards use the lower Mississippi Alluvial Valley (MAV) for wintering habitat, making this an area of emphasis for improving management strategies. In this study, I used mallard observation data from 2009-2014 aerial surveys collected in the Arkansas portion of the lower MAV to explain the abundance and distribution and of mallards. Using spatial hierarchical models and breaking covariate data to 2x2 km grid cells, I analyzed how covariates relate to the changes of abundance and distributions within and among surveys. Mallard abundance …

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian
Conservation Collection
Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in …

Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information …

Physiology Collection
Stereotypies are repetitive and relatively invariant patterns of behavior, which are observed in a wide range of species in captivity. Stereotypic behavior occurs when environmental demands produce a physiological response that, if sustained for an extended period, exceeds the natural physiological regulatory capacity of the organism, particularly in situations that include unpredictability and uncontrollability. One hypothesis is that stereotypic behavior functions to cope with stressful environments, but the existing evidence is contradictory. To address the coping hypothesis of stereotypies, we triggered physiological reactions in 22 horses affected by stereotypic behavior (crib-biters) and 21 non-crib-biters (controls), using an ACTH challenge test. …

Veganism As An Aspiration, Lori Gruen, Robert C. Jones
Dietary Choice and Foods of Animal Origin Collection
iven the violence, objectification, domination, commodification, and oppression inherent in industrialized food production, some conscientious consumers have adopted vegan practices. This chapter discusses two conceptions of veganism, lifestyle/identity veganism, VI, and veganism as a goal/aspiration, VA. It argues that due to conceptual and practical flaws with VI, conscientious consumers should adopt VA. It considers and rejects the so-called compassionate carnivore movement. It then explores arguments denying the casual efficacy of adopting any form of veganism. It concludes that VA can make a difference, and those in consumer cultures are obligated to adopt and practice it.

Seismic Surveys And Marine Turtles: An Underestimated Global Threat?, Sarah E. Nelms, Wendy Dow Piniak, Caroline R. Weir, Brendan J. Godley
Environmental Studies Faculty Publications
Seismic surveys are widely used in marine geophysical oil and gas exploration, employing airguns to produce sound-waves capable of penetrating the sea floor. In recent years, concerns have been raised over the biological impacts of this activity, particularly for marine mammals. While exploration occurs in the waters of at least fifty countries where marine turtles are present, the degree of threat posed by seismic surveys is almost entirely unknown. To investigate this issue, a mixed-methods approach involving a systematic review, policy comparison and stakeholder analysis was employed and recommendations for future research were identified. This study found that turtles have …

Laterality Enhances Numerical Skills In The Guppy, Poecilia Reticulata, Marco Dadda, Christian Agrillo, Angelo Bisazza, Culum Brown
Sentience Collection
It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination. Guppies, Poecilia reticulata, were sorted into left, right and non-lateralized groups using a standard mirror test and their numerical discrimination abilities tested in both natural shoal choice and abstract contexts. Our results show that strongly lateralized guppies have enhanced numerical abilities compared to non-lateralized guppies irrespective of context. These data provide further credence to the notion that …

Agricultural production, processing, and retail industries are major contributors to the Arkansas economy in terms of GDP. Agriculture contributes to the economy through direct agricultural production, value-added processing, and agricultural retail activities, and it also plays an important role through its interactions with other sectors. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy; thus agriculture remains a vital part of Arkansas’ economy. This report: 1) compares the relative size of the Agriculture and Food Sector in Arkansas with those of neighboring states; 2) provides an overview of Arkansas’ economy …

This report presents findings regarding the ways to optimise the performance of livestock working dogs in Australia. The methods available to optimise dog performance include both environmental and genetic factors. The objectives of this study were to identify objective measures of desirable behavioural phenotypes in Australian livestock working dogs and explore genetic parameters of these 'quality of working life' traits within the Kelpie breed. The document reports on genotyping that reveals gene-behaviour associations and describes heritability estimates that underpin a database for potential estimated breeding value (EBV) calculations.

The Flaws And Human Harms Of Animal Experimentation, Aysha Akhtar
Experimentation Collection
Nonhuman animal (“animal”) experimentation is typically defended by arguments that it is reliable, that animals provide sufficiently good models of human biology and diseases to yield relevant information, and that, consequently, its use provides major human health benefits. I demonstrate that a growing body of scientific literature critically assessing the validity of animal experimentation generally (and animal modeling specifically) raises important concerns about its reliability and predictive value for human outcomes and for understanding human physiology. The unreliability of animal experimentation across a wide range of areas undermines scientific arguments in favor of the practice. Additionally, I show how animal …
