Automated Monitoring Of Behaviour In Zebrafish After Invasive Procedures, Anthony G. Deakin, Jonathan Buckley, Hamzah S. Alzu'bi, Andrew R. Cossins, Joseph W. Spencer, Waleed Al'nuaimy, Iain S. Young, Jack S. Thomson, Lynne U. Sneddon

Validation of Animal Experimentation Collection

Fish are used in a variety of experimental contexts often in high numbers. To maintain their welfare and ensure valid results during invasive procedures it is vital that we can detect subtle changes in behaviour that may allow us to intervene to provide pain-relief. Therefore, an automated method, the Fish Behaviour Index (FBI), was devised and used for testing the impact of laboratory procedures and efficacy of analgesic drugs in the model species, the zebrafish. Cameras with tracking software were used to visually track and quantify female zebrafish behaviour in real time after a number of laboratory procedures including fin …

Automated Bioacoustics: Methods In Ecology And Conservation And Their Potential For Animal Welfare Monitoring, Michael P. Mcloughlin, Rebecca Stewart, Alan G. Mcelligott

Conservation Biology and Animal Welfare Collection

Vocalizations carry emotional, physiological and individual information. This suggests that they may serve as potentially useful indicators for inferring animal welfare. At the same time, automated methods for analysing and classifying sound have developed rapidly, particularly in the fields of ecology, conservation and sound scene classification. These methods are already used to automatically classify animal vocalizations, for example, in identifying animal species and estimating numbers of individuals. Despite this potential, they have not yet found widespread application in animal welfare monitoring. In this review, we first discuss current trends in sound analysis for ecology, conservation and sound classification. Following this, …

The Effects Of Providing Social And Nutritional Enrichment To Dairy Calves On Development, Behavior And Learning, Kendra Leigh Kutina

Master's Theses

The objective of this study was to measure the effects of both a nutritional (water nipple) and social (partner calf) enrichment on calf body weight, grain intake, water intake, behavior and learning. The enrichments included 1) water provided from a nipple vs. a bucket (nutritional) and 2) visual and tactile access to a partner vs. isolated rearing with no visual or tactile access to a partner calf (social). A total of 72 Holstein and Jersey dairy calves were pseudo-randomly distributed into 4 treatments at birth [Individual/Bucket (IB), Paired/Bucket (PB), Individual/Nipple (IN), Paired/Nipple (PN)]. Socially and nutritionally enriched calves drank more …

Territorial Behavior Of The Ozark Zigzag Salamander, Plethodon Angusticlavius, Altered By Mode Of Predator Cue And Sex Of Intruder, Sarah E. Heimbach

Graduate Theses/Dissertations

Territorial defense in many species must be balanced with trade-offs in activities such as reproduction and predator avoidance. Adjusting behavior based on current assessments of predation risk and the cost of maintaining or gaining a territory is one way that individuals can balance trade-offs to maximize fitness. I conducted two experiments to determine how Ozark zigzag salamanders, Plethodon angusticlavius, adjust their territorial behavior-based predation risk. First, I tested whether male and female territorial intruders changed their competitive behavior according to whether predation risk is assessed via unimodal (chemical) or multimodal (chemical + physical) cues. Females and males responded differently to …

A Fishy Problem: Effects Of Atlantic Salmon Farming In The Pacific Ocean, Madeleine A. Griffith

Student Theses 2015-Present

In this report, I explore the historical, climatological, economic, and ethical issues created by the contemporary industrial salmon farming practices off Pacific coast of the United States and Canada. Chapter 1 utilizes a variety of sources from Stephen Hume’s A Stain upon the Sea to Miller’s Living in the Environment, to examine the integral part salmon plays in both freshwater and marine ecosystems, the ecosystem services salmon contribute in wild and farmed settings, and the trends in salmon consumption around the world. Chapter 2 examines the historically relevant role salmon held among indigenous societies and how that role has changed …

Developing Sensory Behavioral Assays For Zebrafish Autism Model, Shannon Wagner

Honors College Theses

Individuals of all ages can suffer from a wide variety of symptoms and disabilities that could be diagnosed as Autism Spectrum Disorder (ASD). Due to new methods and technology, individuals are now being diagnosed in the first two years of their life, which is when the signs of ASD are initially exhibited. Individuals diagnosed with ASD share many similar disabilities and symptoms such as hyperactivity to social, visual, and auditory stimuli, as well as hyposensitivity to olfactory stimuli. Neural circuit-based alterations are widely considered as a cause for these behavioral aberrations. We have created behavioral assays using zebrafish larvae to …

Its Skin Is My Skin, Bryan Page

Graduate School of Art Theses

This text examines the complexity of attempting to empathize with bodies that are vastly othered from my own. This broad yet nuanced subject crosses epistemological boundaries and complicates the dualities between both the mind and body, and between the corporeal and the virtual. My desire to better understand the conditions of another’s experience originates from a painful traumatic loss which caused me to feel isolated and incomplete. In response to this suffering, I long to emotionally connect with other beings and create artwork that attempts to bridge the qualia of individual experience.

I am interested in the capacity (or lack …

Contagious Yawning In The Domestic Cat (Felis Catus), Ariel M. Lombardo Aghishian

Theses and Dissertations

This study investigates contagious yawning in domestic cats towards their owners, looking at potential links with empathy. Results showed no significant difference in yawning between conditions. The solitary nature of wildcats and their shared ancestor, and the unique social behavior in domesticated cats may explain these findings.

Observation Of Visitors At A Chimpanzee (Pan Troglodytes Schweinfurthii) Ecotourism Site Reveals Opportunity For Multiple Modes Of Pathogen Transmission, Darcey Glasser

Theses and Dissertations

Chimpanzee (Pan troglodytes) tracking is a popular ecotourism activity across Sub-Saharan Africa, offering visitors a personal wildlife experience. However, chimpanzee ecotourism may increase the risk of disease transmission between chimpanzees and people. This study assessed how tourist behaviors might facilitate cross-species disease transmission in Kibale National Park, Uganda.

The Abundance, Geographical Distribution And Habitat Use Of An Introduced Patas Monkey (Erythrocebus Patas) Population In Southwest Puerto Rico, Magaly Massanet

Graduate Theses

The southwest portion of Puerto Rico is home to introduced free-ranging populations of patas (Erythrocebus patas) and rhesus macaque (Macaca mulatta) monkeys. The rhesus macaque population originated from a colony established in 1961 on the islands of Guayacán and Cuevas off the southwest coast of Puerto Rico as part of the La Parguera Primate Research Center, which was administered by the Caribbean Primate Research Center. The descendants of these escapees have established free-ranging introduced monkey populations in mainland southwest Puerto Rico and the only previous study done on their ecology was conducted from 1990 to 1993 by González- Martínez (1995). …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

The Development Of Socio-Sexual Behavior In Beluga Whales (Delphinapterus Leucas), Malin K. Lilley

Dissertations

The reproductive success of the beluga whale is critical for a species facing extinction in its endangered Cook Inlet, Alaska population. To date, little is known about the mating behavior of these whales in wild populations. On the other hand, observations of beluga whales in human care allow researchers to better understand many aspects of their daily lives and life histories that are difficult to assess in wild populations. Thus far, a catalog of socio-sexual behavior has been established based on observations of belugas; however, the developmental trajectory of socio-sexual behavior is not well-understood. The present study explored how socio-sexual …

Bottlenose Dolphin (Tursiops Truncatus) Vocal Responses To Sonar And Spectrally Pink Background Noise, Maria Zapetis

Dissertations

As human populations rise, the level of man-made noise increases globally. Naval sonar and boat traffic are underwater sound sources of particular concern to marine mammal welfare. To better understand the impact of these noise increases on cetaceans, studies can explore animals’ behavioral changes in response to noise. Studies have investigated the ‘dose-response’ relationship between the received sound pressure level of sonar signals and the behavior of cetaceans in the wild, but exposure studies in controlled environments are limited. The studies in this dissertation examined bottlenose dolphin vocal modifications during various experimental noise treatments. Acoustic recordings previously obtained for bottlenose …

Determining The Relationship Among Cattle Genotype, Hair Coat Score, And Productivity Through The Investigation Of Single Nucleotide Polymorphisms Within Prolactin, Dopamine Receptor D2, And Melatonin Receptor 1a, Erin Davis

Animal Science Undergraduate Honors Theses

Prolactin (PRL), melatonin (MTN), and dopamine (DA) are all hormones that are believed to play a role in the regulation and growth of hair in beef cattle. There are also single nucleotide polymorphisms associated with each of these hormones or their receptors, indicating that the investigation of these polymorphisms could allow them to serve as genetic markers for the future productivity of an animal. The objective of this study was to determine the relationships among cattle genotype, hair coat score, and productivity through the investigation of single nucleotide polymorphisms within prolactin, dopamine receptor D2, and melatonin receptor 1A. Body weights, …

Hormone Signaling, Gene Expression, And Mitochondrial Hormone Receptor Expression In Avian Muscle (Cells), Kentu Rushadd Lassiter

Graduate Theses and Dissertations

Mitochondria are vital to the proper growth and function of muscle cells since they’re responsible for the majority of ATP production used for cellular energy. Previous studies have investigated how differences in mitochondrial function affects feed efficiency (FE) in broilers phenotyped for High and Low FE. Low FE broilers have been shown to have increased levels of reactive oxygen species (ROS), thus contributing to higher levels of oxidative stress and damage seen in these birds. Global gene and protein expression studies conducted on breast muscle of the High FE and Low FE phenotypes have suggested that differences in mitochondrial function …

Evaluation Of Herd Size Management Strategies, Colson A. Tester

Graduate Theses and Dissertations

This thesis is comprised of two studies examining the effects of price signal based herd size management strategies on profitability of cow-calf operations. Herd size management strategies were evaluated across the previous two cattle cycles, 1990-2014, using a fixed land resource and included a variety of production scenarios. These scenarios varied in terms of stocking rates, fertilizer applications rates, and calving season. Each scenario was also analyzed both with and without weather effects on forage production. Weather effects were simulated using a production index derived from satellite imagery across the observed 25-year period. Three herd size management strategies: i) constant …

Optimization Of The Light Environment For Broiler Chickens, Douglas J. Aldridge

Graduate Theses and Dissertations

The use of artificial light sources has been necessitated by the use of fully enclosed rearing facilities for improved environmental control. Light Emitting Diodes (LED) have been developed as a light source that reduce the utilities required to provide equal light to that of incandescent sources. The following reports were carried out to investigate the effects of two light color temperatures, light intensity and light intensity gradients on broiler chicken production and behavior. The first investigation consisting of two consecutive trials investigated the effect of two light color temperatures (2700 K and 5000 K) in addition to the preference for …

Broiler Breeder Amino Acid Levels And Progeny Nutritional Status, Leasea Butler

Graduate Theses and Dissertations

Crude protein needs of chickens have changed due to genetic line differences and selection of those lines for differing broiler traits. Standard commercial broiler strains have been selected to be used to meet multiple processing categories typically at live body weights less than 3.5 kg. In the last two decades high-yielding broiler strains were introduced into the commercial market. These breeds are known as the Cobb 700 and Ross 708. The works included within are focused on the Cobb 700 high-yielding broiler strain, and its response to crude protein, with emphasis on digestible lysine.

Animal Experimentation: Working Towards A Paradigm Change, Kathrin Herrmann (Ed.), Kimberley Jayne (Ed.)

eBooks

Animal experimentation has been one of the most controversial areas of animal use, mainly due to the intentional harms inflicted upon animals for the sake of hoped-for benefits in humans. Despite this rationale for continued animal experimentation, shortcomings of this practice have become increasingly more apparent and well-documented. However, these limitations are not yet widely known or appreciated, and there is a danger that they may simply be ignored. The 51 experts who have contributed to Animal Experimentation: Working Towards a Paradigm Change critically review current animal use in science, present new and innovative non-animal approaches to address urgent scientific …

Hydrolyzable tannins consist of gallate groups connected via ester linkages to a carbohydrate (D-glucose)

The Prussian Blue method was used to determine hydrolyzable tannin content

Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont

Professional Science Research Ethics Collection

Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals, which our analysis of 206 journals suggests are either absent (34%), weak, incoherent, or neglected by researchers, could provide a practical, effective, and rapidly imposed …

Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne

Student Scholar Showcase

Female Dolomedes scriptus, the striped fishing spider, serve as model organisms exhibiting pheromone production as a means of chemical signaling. Previous work has shown that male fishing spiders are responsive to female silk, and preferentially court in the presence of silk from mature virgins. In our research, we hypothesized that mature females produced larger quantities of silk than penultimate females in an attempt to elicit greater male mating response. Female spiders of both age statuses were kept for two days in a gridded tank. Sub-sampling of silk lines that crossed a random portion of the grid produced results signifying …

Influence Of Indirect Cues And Vegetation Density On Foraging Behavior In Snowshoe Hares (Lepus Americanus), Zachary Lankist

Thinking Matters Symposium Archive

Prey avoid chemical cues from predators at feeding sites because the risk of death outweighs the benefit of food. However, we lack information regarding avoidance of chemical cues from competitors as well as how foraging behavior changes alongside vegetative cover. To test if chemical cues and vegetative cover alter prey vigilance, number of visits, and time spent at feeding sites, I observed snowshoe hares (Lepus americanus) in plots containing coyote (Canis latrans; predator) and moose (Alces alces; competitor) urine across a spectrum of vegetation densities. Snowshoe hares significantly reduced the number of visits to feeding plots when coyote or moose …
