The Development Of Social Behavior In The Tibetan Macaque (Macaca Thibetana), Rose Amrhein

All Master's Theses

Social cognition is vital for the proper integration into adulthood for any highly social animal species. The development of social intelligence during the childhood and adolescence of a social organism affects the individual throughout its life. This social intelligence allows for the establishment and maintenance of bonds through the formation of empathy, the understanding of intention and emotion, and theory of mind in some species. Changes to the rate and effectiveness of social development could lead to an individual incapable of integrating into the social environment of adulthood. Yet, much still needs to be learned about the process and influences …

Mommy Issues: Do Differential Rearing Histories Affect The Social Behavior Of Captive Chacma Baboons (Papio Ursinus), Madeleine Spencer

All Master's Theses

I observed the behavior of 17 chacma baboons (Papio ursinus) in order to understand the relationship between rearing history, dominance hierarchy, and social behavior. The Centre for Animal Rehabilitation and Education (C.A.R.E.) has utilized hand-rearing in the past and is currently using a surrogate-rearing method. Hand-rearing involves one or more primary caregivers attending to an infant for 6 – 12 months. Surrogate-rearing involves one individual being the primary surrogate for the first 3 months of the infant’s life prior to bonding her or him to an adult female baboon before integrating both back into the surrogate’s troop. Mother-reared …

The Presence Of Food Likely Has No Influence On Substrate Use Of Tokay Geckos (Gekkonidae: Gekko Gecko), Timothy Zatkos

Williams Honors College, Honors Research Projects

Geckos and their adhesive capabilities have been thoroughly examined for the past two decades, especially in terms of adhesion and its mechanics. However, few studies have focused on how the adhesive performance of geckos influences ecologically relevant behaviors (e.g., habitat/substrate use). The limited work on the topic in the laboratory suggests that geckos spend more time on substrates in which their adhesive capabilities are superior, such as glass. In their natural habitat, however, multiple factors besides adhesive performance alone is likely to collectively impact the substrate use of geckos. The presence of food is one such factor. Here I examined …

The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …

Spaced Training In The 5csrtt Proves Beneficial In Early Levels, Rebecca Renee Warren

Senior Independent Study Theses

ADHD is a neurodevelopmental disorder characterized by inattentiveness, impulsivity, and hyperactivity. Due to these characterizations, children with ADHD typically exhibit lower academic performance which has been improved by spacing out academic training. Yet no study has performed spacing in an ADHD population. Spaced training involves studying over short periods for multiple days rather than multiple hours in one day, or massed training. Using a rat model of ADHD, known as the SHR strain, the present study assessed how spacing training from 90-trials a day to 45-trials a day in the 5CSRTT would improve performance abilities. Additionally, the impact of spaced …

Sympathy For Cecil: Gender, Trophy Hunting, And The Western Environmental Imaginary, Eric S. Godoy

Faculty Publications - Philosophy

This article draws from political ecology and ecofeminism to examine sympathy, expressed by record-breaking donations from North Americans, for the death of Cecil the Lion. The overlapping normative critique offered by these two perspectives together demonstrates how sympathy is disclosive of power relations. Sympathy reveals, relies upon, and reinforces different forms of gender, racial, and neocolonial domination; especially when western sympathy remains ignorant of the power relations, including their politics and histories, that shape attitudes toward non-human animals and grant them status as members of the (western) moral community.

Animal Welfare Science And “A Life Worth Living” For Wild And Captive Elephants, Lindsay R. Mehrkam, Otto Fad

Animal Sentience

Baker & Winkler (2020) propose restoring elephants to a state of “wildness” and a “life worth living” by reintroducing captive elephants to the hands of indigenous mahout cultures and practices. To evaluate this proposal, we must define operationally a number of critical concepts in a species-centric, individualistic way, avoiding human-centric opinions and romanticized notions of the wild. Animal welfare science can help create greater synergy between ex-situ zoological institutions and in-situ elephant conservation, and welfare efforts that respect and value the cultures of both species.

Owner Perceptions Of Cat-Human Communication, Kendal Cler

EWU Masters Thesis Collection

This study focuses on cat to human communication with an emphasis on the way humans perceive cats' communicative signals. Compared to other animals, the domestication of cats has been a slow process and humans have begun to recognize the communicative signals from cats and vice versa. Based on the results of this survey research, humans have started to notice different forms of communication from cats, and are able to decipher their cat’s needs, most of the time. Owners of cats in this study appear to be projecting human values of communication onto their cats. Cats have begun to adjust their …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Jeffrey Stevens Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Evaluation Of The Impacts Of Radio-Marking Devices On Feral Horses And Burros In A Captive Setting, Kathryn A. Schoenecker, Sarah R. B. King, Gail H. Collins

Human–Wildlife Interactions

Radio-collars and other radio-marking devices have been invaluable tools for wildlife managers for >40 years. These marking devices have improved our understanding of wildlife spatial ecology and demographic parameters and provided new data facilitating model development for species conservation and management. Although these tools have been used on virtually all North American ungulates, their deployment on feral horses (Equus ferus caballus) or burros (E. asinus) has been limited. To determine if radio-collars and radio-tags could be safely deployed on feral equids, we conducted a 1-year observational study in 2015 to investigate fit and wear of radio-collars …

Of Elephants And Men, Helen Kopnina

Animal Sentience

Baker & Winkler’s target article is well-researched and thought-provoking, but I do have four points of contention: (1) The proposal to entrust elephants to traditional mahout culture has restricted elephants’ freedom of movement and reproduction and (ab)used them. (2) The concept of “indigenous” simultaneously reifies and denigrates the “noble savages”, privileging only human indigenous groups, ignoring nonhuman indigenes. (3) Most lifestyles have been globalized under consumer-economic and anthropocentric worldviews. (4) The fact that people (including mahouts) are part of nature does not mean they are benevolent, any more than cities, monocultures, or roads are.

How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer

Animal Sentience

Treves et al. (2019) propose a non-anthropocentric approach to conservation biology for the ‘just preservation’ of non-humans. Some of our current ways of ranking conservation efforts based on benefits to humans are indeed critically flawed, but we doubt that a completely non-anthropocentric approach is possible at this time. We propose a way to generate public support for those non-human species that may otherwise be overlooked in policy-making and conservation efforts.

Minds Without Spines: Evolutionarily Inclusive Animal Ethics, Irina Mikhalevich, Russell Powell

Animal Sentience

Invertebrate animals are frequently lumped into a single category and denied welfare protections despite their considerable cognitive, behavioral, and evolutionary diversity. Some ethical and policy inroads have been made for cephalopod molluscs and crustaceans, but the vast majority of arthropods, including the insects, remain excluded from moral consideration. We argue that this exclusion is unwarranted given the existing evidence. Anachronistic readings of evolution, which view invertebrates as lower in the scala naturae, continue to influence public policy and common morality. The assumption that small brains are unlikely to support cognition or sentience likewise persists, despite growing evidence that arthropods …

Human Relationships With Domestic And Other Animals: One Health, One Welfare, One Biology, Ariel M. Tarazona, Maria C. Ceballos, Donald M. Broom

Human-Animal Relationships Collection

Excessive human population growth, uncontrolled use of natural resources, including deforestation, mining, wasteful systems, biodiversity reduction by agriculture, and damaging climate change affect the existence of all animals, including humans. This discussion is now urgent and people are rethinking their links with the animals we use for clothing, food, work, companionship, entertainment, and research. The concepts of one health, one welfare, and one biology are discussed as a background to driving global change. Nothing should be exploited without considering the ethics of the action and the consequences. This review concerns domesticated animals, including those used for human consumption of meat, …

Reported Acquisition Practices Of Australian Dog Owners, Simone A. Blackman, Bethany J. Wilson, Alistair R. Reed, Paul D. Mcgreevy

Rescue and Surrender of Companion Animals Collection

In Australia, the UK and the US dog ownership is prevalent with an estimated 40% of Australian households, 25% of UK households, and 50% of US households owning a dog. Once acquired, a dog usually becomes a family companion so, unlike a faulty product, it can rarely be returned or resold without some emotional impact on both the acquirer and the dog. Regarding the reality of dog relinquishment, there is a growing need for cross-disciplinary research that considers how dog owners are making their acquisition choices and, if prioritising different attributes, leads to more optimal acquisition choices. This research collected …

The Demography And Practice Of Australians Caring For Native Wildlife And The Psychological, Physical And Financial Effects Of Rescue, Rehabilitation And Release Of Wildlife On The Welfare Of Carers, Bruce Englefield, Steve Candy, Melissa J. Starling, Paul Mcgreevy

Human-Animal Bonds Collection

The rescue, rehabilitation and release of injured and orphaned Australian wildlife is managed by over 20,000 carers, mostly voluntarily. These volunteers experience mental, physical and financial challenges that have not been researched adequately. This study collated the responses (n = 316) to a survey conducted among Australian wildlife carers who actively foster orphaned joeys for hand-raising and injured adult mammals for rehabilitation and release. It confirmed 86% of rehabilitators are female, 70% are over the age of 46 years and their prime motivation is an affinity with animals. The average time spent in the sector is 11.5 years, and the …

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy

Physiology Collection

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire …

Companion Dog Acquisition And Mental Well-Being: A Community-Based Three-Arm Controlled Study, Lauren Powell, Kate M. Edwards, Paul D. Mcgreevy, Adrian Bauman, Anthony L. Podberscek, Brendon Neilly, Catherine Sherrington, Emmanuel Stamatakis

Human-Animal Relationships Collection

Background

Dog ownership is suggested to improve mental well-being, although empirical evidence among community dog owners is limited. This study examined changes in human mental well-being following dog acquisition, including four measures: loneliness, positive and negative affect, and psychological distress.

Methods

We conducted an eight-month controlled study involving three groups (n = 71): 17 acquired a dog within 1 month of baseline (dog acquisition); 29 delayed dog acquisition until study completion (lagged control); and 25 had no intentions of acquiring a dog (community control). All participants completed the UCLA Loneliness Scale (possible scores 0–60), Positive and Negative Affect Schedule …

Unique New York: Examining The Impact Of Breed Labels, Phenotypic Variations, And Geography On Length Of Stay In A Multi-Location New York Limited Intake Animal Shelter, Nicole Passmore

Theses and Dissertations

New York City (NYC) is a unique area for a shelter welfare as it has limited dog-friendly housing and an abundance of dogs. A common barrier to entry for NYC dog adopters trying to rent apartments is the breed label the shelter assigned to their dog, despite the fact breed labelling is primarily based off intuition and physical appearance. Following research by Gunter, Barber and Wynne (2016) that saw adoption rates at a Florida animal shelter increase following the removal of breed labels from the shelter’s kennel cards, some shelters ceased using breed labels. One was Bideawee, a limited admission …

Investigating Egg Storage Conditions, Hatch Characteristics, And Feeding Methods Of Commercially Produced Poultry, Joshua R. Deines

Graduate Theses and Dissertations

Advancements in poultry research continue to add knowledge and understanding to an already technical industry. Such information has led to new developments in early feeding strategies which provide nutrients to broiler chicks while in the egg or during transport. This wealth of knowledge in poultry research extends beyond chickens and is utilized for other species, such as quail and pheasants, including how fertile eggs are stored and incubated. However, methods of early feeding broilers have not been investigated in industry relevant approaches to understand its effects, including how timing of feed access interacts with the hatch window. As well, quail …
