Conservation Coverage: An Assessment Of The Protection Of Highly Threatened Species Of Birds And Mammals In Tanzania, Adolfo Castro Domínguez

Independent Study Project (ISP) Collection

43 species of birds and mammals are either critically endangered or endangered within Tanzania. Compromised to halt the rapid loss of biodiversity, the Tanzanian government, several non-governmental organizations, government agencies and zoological institutions are attempting to preserve these highly-threatened species. This project assesses the current state of conservation for those species by: 1) diagnosing their captive populations in Tanzania, through visits to zoological institutions in the country and in a global scale by using ZIMS, a global database for zoos and aquariums. 2) determining the protected areas in which the species are found by overlapping distribution maps with protected areas …

Using The Five Domains Model To Assess The Adverse Impacts Of Husbandry, Veterinary, And Equitation Interventions On Horse Welfare, Paul Mcgreevy, Jeannine Berger, Nic De Brauwere, Orla Doherty, Anna Harrison, Julie Fiedler, Claudia Jones, Sue Mcdonnell, Andrew Mclean, Lindsay Nakonechny, Christine Nichol, Liane Preshaw, Peter Thomson, Vicky Tzioumis, John Webster, Sarah Wolfensohn, James Yeates, Bidda Jones

Equine Husbandry and Welfare Collection

The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a

broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; n = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were considered within 14 contexts: C1Weaning; C2 Diet; C3 Housing; C4 Foundation training; C5 …

Bat Detective—Deep Learning Tools For Bat Acoustic Signal Detection, Oisin Mac Aodha, Rory Gibb, Kate E. Barlow, Michael Firman, Robin Freeman, Briana Harder, Libby Kinsey, Gary R. Mead, Stuart E. Newson, Ivan Pandourski, Stuart Parsons, Jon Russ, Abigel Szodoray-Paradi, Elena Tilova, Mark Girolami, Gabriel Brostow, Kate E. Jones

Bioacoustics Collection

Passive acoustic sensing has emerged as a powerful tool for quantifying anthropogenic impacts on biodiversity, especially for echolocating bat species. To better assess bat population trends there is a critical need for accurate, reliable, and open source tools that allow the detection and classification of bat calls in large collections of audio recordings. The majority of existing tools are commercial or have focused on the species classification task, neglecting the important problem of first localizing echolocation calls in audio which is particularly problematic in noisy recordings. We developed a convolutional neural network based open-source pipeline for detecting ultrasonic, full-spectrum, search-phase …

Longitudinal Trends In The Frequency Of Medium And Fast Race Winning Times In Australian Harness Racing: Relationships With Rules Moderating Whip Use, Bethany Wilson, Bidda Jones, Paul Mcgreevy

Sport and Working Animal Welfare Collection

The use of whips in racing is subject to current debate, not least because the prospect that fatigued horses cannot respond renders the practice futile and inhumane. The racing industries maintain whip use is a form of encouragement and that the rules of racing that govern whip use safeguard horse welfare. The current study examined longitudinal trends in the frequency of medium and fast race winning times in Australian harness racing between September 2007 and August 2016 to explore relationships with a series of changes that moderated whip use. The first change, introduced January 2010, moderated whip action so that …

Contextual Fear Learning And Memory In Alternative Stress Coping Styles, Matthew R. Baker, Ryan Y. Wong

UNO Student Research and Creative Activity Fair

Animals frequently must overcome stressors, and the ability to encode and recall these salient experiences is essential to an individual’s survival. Across many taxa, studies have documented two alternative stress coping styles (proactive and reactive) that differ in behavior, cognition, stress physiology, and underlying neuromolecular mechanisms. The role of stress in cognitive traits (e.g. learning and memory) has been well documented, however, the influence of an animal’s stress coping style on learning and memory capabilities is only beginning to be understood. Here, we developed a contextual fear learning paradigm to characterize learning and memory differences between proactive and reactive stress …

Biophilia: Alienation And Solidarity, Ralph Acampora

Between the Species

Biophilia, theorized by Fromm, Wilson, and Kellert, is examined as a potential support for a pro-animal ethos. First, I look at the idea and its definitions at the hands of its chief theorizers. Then I investigate how different stages of human cultural development (foraging, pastoralism, industrial agriculture) have influenced different aspects of biophilia—especially as this bears on animal alienation. Finally, I consider possible remedies in the form of renewed patterns of solidarity with other species, one of which transforms Marx’ concept of species-being. The article has ethical implications, but it is essentially a work in philosophical anthropology.

Flogging Tired Horses: Who Wants Whipping And Who Would Walk Away If Whipping Horses Were Withheld?, Paul D. Mcgreevy, Mark D. Griffiths, Frank R. Ascione, Bethany Wilson

Sport and Working Animal Welfare Collection

Recent studies have cast doubt on the effectiveness of whipping horses during races and this has led to questions concerning its continuing justification. Furthermore, it has been argued that whipping tired horses in racing is the most televised form of violence to animals. The present study used de-identified data from a recent independent Australian poll (n = 1,533) to characterise the 26% of respondents (113 females and 271 males) who support the whipping of racehorses and the 10% of racing enthusiasts in the sample (44 females and 63 males) who would stop watching races and betting on them if whipping …

Justifiability And Animal Research In Health: Can Democratisation Help Resolve Difficulties?, Shaun Yon-Seng Khoo

Morality and Ethics of Animal Experimentation Collection

Current animal research ethics frameworks emphasise consequentialist ethics through cost-benefit or harm-benefit analysis. However, these ethical frameworks along with institutional animal ethics approval processes cannot satisfactorily decide when a given potential benefit is outweighed by costs to animals. The consequentialist calculus should, theoretically, provide for situations where research into a disease or disorder is no longer ethical, but this is difficult to determine objectively. Public support for animal research is also falling as demand for healthcare is rising. Democratisation of animal research could help resolve these tensions through facilitating ethical health consumerism or giving the public greater input into deciding …

Cognitive Dysfunction In Naturally Occurring Canine Idiopathic Epilepsy, Rowena M.A. Packer, Paul D. Mcgreevy, Hannah Salvin, Michael Valenzuela, Chloe M. Chaplin, Holger A. Volk

Neurology Collection

Globally, epilepsy is a common serious brain disorder. In addition to seizure activity, epilepsy is associated with cognitive impairments including static cognitive impairments present at onset, progressive seizure-induced impairments and co-morbid dementia. Epilepsy occurs naturally in domestic dogs but its impact on canine cognition has yet to be studied, despite canine cognitive dysfunction (CCD) recognised as a spontaneous model of dementia. Here we use data from a psychometrically validated tool, the canine cognitive dysfunction rating (CCDR) scale, to compare cognitive dysfunction in dogs diagnosed with idiopathic epilepsy (IE) with controls while accounting for age. An online cross-sectional study resulted in …

Social Influences On Songbird Behavior: From Song Learning To Motion Coordination, Iva Ljubičić

Dissertations, Theses, and Capstone Projects

Social animals learn during development how to integrate successfully into their group. How do social interactions combine to maintain group cohesion? We first review how social environments can influence the development of vocal learners, such as songbirds and humans (Chapter 1). To bypass the complexity of natural social interactions and gain experimental control, we developed Virtual Social Environments, surrounding the bird with videos of manipulated playbacks. This way we were able to design sensory and social scenarios and test how social zebra finches adjust their behavior (Chapters 2 & 3). A serious challenge is that the color output of a …

How The Egg Rolls: A Morphological Analysis Of Egg Shape In The Context Of Displacement Dynamics, Ian R. Hays

Theses and Dissertations

Very little is known about how morphology effects the motion, stability and the resulting viability of avian eggs. The limited research that exists focuses on the pyriform or ‘pointed’ egg shapes found in the Alcidea family. This unusual shell form is thought to suppress displacement and prevents egg loss on the cliffside nesting habitat of the Uria genera. Unfortunately, these studies never isolated or quantify the specific morphological features (elongation, asymmetry and conicality) of these pyriform eggs, which limits their applicability to other taxa and hampers a robust proof of concept. We isolated each feature as a variable, produced models …

Chickens Play To The Crowd, Cinzia Chiandetti

Animal Sentience

The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.

Encoding Of Emotional Valence In Wild Boar (Sus Scrofa) Calls, Anne-Laure Maigrot, Edna Hillmann, Elodie Briefer

Bioacoustics Collection

Measuring emotions in nonhuman mammals is challenging. As animals are not able to verbally report how they feel, we need to find reliable indicators to assess their emotional state. Emotions can be described using two key dimensions: valence (negative or positive) and arousal (bodily activation or excitation). In this study, we investigated vocal expression of emotional valence in wild boars (Sus scrofa). The animals were observed in three naturally occurring situations: anticipation of a food reward (positive), affiliative interactions (positive), and agonistic interactions (negative). Body movement was used as an indicator of emotional arousal to control for the effect of …

Mental Stress From Animal Experiments: A Survey With Korean Researchers, Minji Kang, Ahram Han, Da-Eun Kim, Troy Seidle, Kyung-Min Lim, Seungjin Bae

Morality and Ethics of Animal Experimentation Collection

Animal experiments have been widely conducted in the life sciences for more than a century, and have long been a subject of ethical and societal controversy due to the deliberate infliction of harm upon sentient animals. However, the harmful use of animals may also negatively impact the mental health of researchers themselves. We sought to evaluate the anxiety level of researchers engaged in animal use to analyse the mental stress from animal testing. The State Anxiety Scale of the State-Trait Anxiety Inventory (STAI) was used to evaluate how researchers feel when they conduct animal, as opposed to non-animal, based experiments …

From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Barbuda and Antigua’s national animal is the fallow deer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a …

Mesotocin Influences Pinyon Jay Prosociality, Juan Duque, Whitney Leichner, Holly Ahmann, Jeffrey R. Stevens

Jeffrey Stevens Publications

Many species exhibit prosocial behavior, in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different payoff distributions: Prosocial trials delivered food to both the subject and either an empty cage or a partner …

Mother-Infant Interactions In A Wild Population Of Macaca Nemestrina (Linnaeus), Emily M. Dura, Lori K. Sheeran, Nadine Ruppert, Clay P. Arango, Sofia K. Blue

Student Published Works

Until now, mother-infant relationships have not been studied in a wild population of the Southern Pig-tailed Macaques Macaca nemestrina. We observed six mother-infant dyads from April 2016 to September 2016 in the Segari Melintang Forest Reserve, Peninsular Malaysia using focal sampling methods from the perspectives of both individuals. We hypothesized that as infant age increased, the same important mother-infant behaviours, previously observed to change in captive pig-tailed macaque mother-infant studies, would also change over time in field conditions. We expected that as the infant ages, mothers would decrease their rates of restraint and retrieval, and increase their rates of …

Autism Spectrum Disorder (Asd) And Equine Assisted Therapy: An Integrative Review Of The Literature, Brittany R. Selzer

Honors Undergraduate Theses

The purpose of this integrative review of the literature is to examine the effectiveness of equine assisted therapy with individuals diagnosed with Autism Spectrum Disorder (ASD). An extensive review of the literature was conducted regarding children diagnosed with ASD who received equine therapy, equine psychotherapy, therapeutic horseback riding, or horse therapy. Inclusion criteria include articles written in the English language, articles that were peer-reviewed, and had a publication date from 2006 to present. Fourteen articles were analyzed regarding children with ASD who participated in different types of equine therapy. The majority of the studies found individuals with ASD who participated …
