Understanding How Temperature Influences European Starling’S Reproductive Success, Grace Fatoyinbo, Sarah Guindre-Parker

Symposium of Student Scholars

Many habitats face fluctuating temperatures year round. The animals that live there are typically able to adjust their behaviors to match these conditions. When temperatures become too extreme, however, it could potentially start having a negative effect on the animal’s reproductive success. In birds, for example, severe climate can affect their eggs and nestlings due to nestlings lacking the ability to thermoregulate. The parents then have to bear the responsibility of thermoregulation for their young, through a behavior called incubation or brooding. European starlings (Sturnus vulgaris) are a species of birds common across the United States where both …

Using Machine Learning Methods To Predict The Movement Trajectories Of The Louisiana Black Bear, Daniel Clark, David Shaw, Armando Vela, Shane Weinstock, John Santerre, Joseph D. Clark

SMU Data Science Review

In 1992, the Louisiana black bear (Ursus americanus luteolus) was placed on the U.S. Endangered Species List. This was due to bear populations in Louisiana being small and isolated enough where their populations couldn’t intersect with other populations to grow. Interchange of individuals between subpopulations of bears in Louisiana is critical to maintain genetic diversity and avoid inbreeding effects. Utilizing GPS (Global Positioning System) data gathered from 31 radio-collared bears from 2010 through 2012, this research will investigate how bears traverse the landscape, which has implications for gene exchange. This paper will leverage machine learning tools to improve upon existing …

Some (Im)Material Girls, Living In (Im)Material Worlds, With Seeds, Stars, And Shit, Matthew Weiderspon

Theses and Dissertations

This writing situates material and gestural vocabularies cultivated in my artwork in relation to my lived experience; primarily my rural upbringing in Colorado. Scattered floor dispersals, calling sounds, and bodily movements desire reconsiderations of hope in precarity through a disorientation of place, association, scale, and language.

Analysis Of Multigenerational Behavioral Effects Of Dietary Benzo[A]Pyrene Exposure In Adult Zebrafish, Mary Beth Gillespie

Honors Theses

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon that is linked to negative reproductive and developmental effects in humans and animals. Because BaP is carcinogenic, and its continued presence in the environment allows it to be inhaled and ingested, better understanding of the effects of BaP is needed. To determine the behavioral effects of BaP exposure, zebrafish were used as a model. Wild-type zebrafish (5D) underwent two separate 21-day dietary exposures to 2.5 and 25 μg BaP/g fish to compare how BaP exposure affects locomotor activity. Following the dietary exposure, fish were mated to obtain and raise the F1 generation to …

The Importance Of The Relationship Between Domestic Violence Victims And Their Pets, Emily Ryan

Master’s Theses and Projects

The purpose of this thesis is to explore the relationship between domestic violence and animal abuse with the goal of adding to the literature in this area. This study collected data from domestic violence and homeless shelters across the United States by sending a questionnaire via email. Two themes emerged based on the questionnaire responses, first, shelters reported that victims disclosed their fear of leaving an abusive situation due to abuse or threat of abuse to a family pet. And second, shelters indicated that they are unable to accommodate pets due to either, health and safety reasons, or financial difficulties. …

Influence Of Encapsulation Of Supplemental Amino Acids On Their Utilization In Broilers, Ethan A. Collins

Poultry Science Undergraduate Honors Theses

This study was developed to assess whether microencapsulation of amino acids (AA) improves their absorption to increase broiler growth performance and reduce nitrogen excretion compared to standard feed-grade AA. Five hundred and sixty Ross 708 male broilers were randomly distributed to 70 battery cages and reared for 21 days. Reported data is grouped into periods: 0-7 days, 0-14 days, and 0-21 days. A total of 5 treatment diets were fed: an industry-based control and 4 diets with decreased levels of methionine, lysine, and threonine in either encapsulated or free forms, with or without a botanical feed additive. Encapsulated AA increased …

Evaluation Of Weight Gain, Feed Intake, Feed Conversion And Oocyst Shedding Of Eimeria Maxima And Eimeria Acervulina In Broiler Chickens, Lauren Laverty

Poultry Science Undergraduate Honors Theses

The purpose of the present study was to evaluate the day and the time of sample collection of an

experimental challenge with Eimeria maxima (EM) and Eimeria acervulina (EA) in broiler chickens. One day old male Cobb-Vantress broiler chickens were randomly allocated to one of three groups with ten replicates (n=8 chickens/replicate). Chickens were placed in battery cages with a controlled age-appropriate environment: Group 1) Negative control (no challenge or treatment); 2) Challenge control (Eimeria challenge only); 3) Challenge + Salinomycin. Challenged chickens were orally gavaged with the mixed culture of EM/EA (10,000 sporulated EM containing 4% wild-type EA) …

Habitat Characteristics Or Protected Area Size: What Is More Important For The Composition And Diversity Of Mammals In Nonprotected Areas?, Wenbo Li, Jinhua Li, Peipei Yang, Bowen Li, Chao Liu, Lixing Sun

Biology Faculty Scholarship

The margins of protected areas are usually considered to have greater forest degradation, and given that most mammals live outside protected areas, researchers and conservation practitioners are increasingly recognizing that nonprotected areas must be incorporated into conservation strategy. However, the strategy used to manage these areas still involves increasing the size of protected areas, while not considering the habitat characteristics and requirements of the species. In this study, during a 3-year period, camera trap and habitat characteristic surveys were used to estimate composition, diversity, and habitat characteristics of mammals to determine habitat characteristics or increase the size of protected areas …

Shelter Dogs Need A Home: The Effect Of Enrichment And Human Contact On The Welfare And Adoptability Of Shelter Dogs, Hannah G. Clark

Honors Projects

It comes as no surprise that an animal shelter can be a stressful place for dogs. Shelter conditions, accompanied by multiple, novel stimuli, produce a stressful environment that cause hormonal and behavioral responses in dogs housed in shelters. Many of the stereotypical behaviors produced by the stress of living in a shelter, which tend to worsen as length of stay increases, are undesirable to potential adopters. However, many studies have shown that enrichment with a variety of toys, exercise, and human interaction can buffer the stress response in shelter dogs and improve their well-being. Implementing obedience training and temporary fostering …

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty

Animal Science Undergraduate Honors Theses

This study will focus on how maternal phosphorus status of beef heifers affects the growth and performance of their calves. Heifers have been offered free-choice mineral with either 0 or 4% supplemental phosphorus from 30 days after weaning until calving. A study by H. Hilfiker, a University of Arkansas honors student, investigated the effects of these treatments from 30 days after weaning until 60 days after the breeding season when heifers were confirmed to be bred or open. For this developing heifer project 64 crossbred Angus heifers were assigned randomly into 8 groups (8 heifers/ group) before assigning each group …

Analysis Of The White-Tailed Deer Population Of Hobbs State Park, Jesse Morrison

Biological and Agricultural Engineering Undergraduate Honors Theses

White Tailed deer (Odocoileus virginianus) are the only deer species native to Arkansas, playing a crucial role in the ecosystem. Healthy deer populations are important for environmental and human wellbeing, and overpopulation can lead to poor herd health, overgrazing, increased vehicle collisions, and transmission of diseases. Monitoring deer populations through surveys can be a useful tool in managing wildlife and maintaining Arkansas’ natural resources.

This study analyzed trends in Hobbs State Park’s deer population and estimated the current roadside deer population of the park. Data from past surveys was analyzed for trends using a Mann-Kendall Test, and a distance sampling …

Role Of Reptile-Invertebrate Interactions In Enigmatic Reptile Declines, Meredith Swartwout

Graduate Theses and Dissertations

Reptile populations are declining world-wide and the mechanisms behind many of these declines remain enigmatic. Food web interactions (i.e., reduced prey availability or increased predation) have been implicated behind some reptile declines. However, relatively little is known about predation on lizard and snake eggs, despite egg survival being important for population dynamics of some species. Ants are important predators of squamate reptile eggs in tropical and temperate systems. In Costa Rica, long-term declines in terrestrial anole lizards were linked with reduced leaf litter depth, a factor that could influence egg vulnerability to ant predation. Fire ants (genus Solenopsis) are aggressive …

Methods To Reducing Weaning Stress In Early Weaned Spring Beef Calves, Matthew Daniel Hahn

Graduate Theses and Dissertations

Reducing weaning stress in beef calves can have dramatic benefits to the health, growth, and performance to beef calves post-weaning. Studies have shown that providing creep feed to calves during the pre-weaning period can improve their nutritional status, which can better prepare them for the stresses they will be exposed to during the weaning process. Studies have also shown that two-stage weaning can reduce the stresses associated with weaning. Previous research has suggested that this method resulted in dramatic changes in behavioral signs associated with stress. The objective of this study was to evaluate the effects of two-stage weaning with …

Quantifying The Leaching Of Nutrients And Metals In A Pasture Soil As Affected By Excreta Of Ruminants Fed Alternative Diets, Ian Kennedy

Graduate Theses and Dissertations

The leaching of nitrate through the soil profile and into adjacent water systems has been a leading cause of water pollution and results in the loss of a valuable nutrient from animal production systems. Forage-based animal production systems may be improved through manipulation of animal diets that incorporate tannins and total polyphenolic compounds with feed, increasing the amount of nitrogen (N) retained by an animal/decreasing rates of digestion and altering the N-containing compounds that are excreted and deposited onto soil. Incorporating the forage legumes sericea lespedeza (Lespedeza cuneate [Dumont de Courset] G. Don) and lablab (Lablab purpurues L.) into the …

Influence Of Local- And Landscape-Scale Factors On Avian Assemblage In Fragmented Tallgrass Prairie Landscape, Pooja Panwar

Graduate Theses and Dissertations

Agricultural expansion and increasing urbanization are driving rapid landscape modification in the Tallgrass prairies ecosystem and are affecting biodiversity at multiple spatial scales. Thus, the conservation of fragmented grassland and steeply declining grassland avifauna is dependent on the relationship between local- and landscape-scale factors and avian assemblage. We also need to understand how these factors, operating at different spatial scales, drive the occupancy of different guilds in the assemblage. We conducted repeated point count surveys during the breeding season of 2019 at 66 grassland sites across Arkansas and Missouri, USA. We developed a multi-species occupancy model to estimate species richness, …

Evaluation Of Nutritional Factors That Influence The Efficacy Of Tributyrin As A Feed Additive For Broilers, Brooke Bodle

Graduate Theses and Dissertations

Tributyrin (TB) is a glyceride ester of butyrate that has the potential to improve broiler performance and intestinal development. Therefore, to fully evaluate this potential, three experiments were conducted to evaluate effect of tributyrin (TB) on broiler growth performance, nutrient digestibility, carcass characteristics, intestinal morphology, and gastrointestinal function in birds fed diets varying in composition reared in battery cages and floor pens. Experiment 1 explored the supplementation of graded doses of TB and its impact upon growth performance, nutrient digestibility, and carcass characteristics in a step-down program when added to a reduced energy and amino acid diet. A linear reduction …

Relationship Of Underline Scores And Production Traits In Beefmaster Cattle, Bryan R. Kutz

Graduate Theses and Dissertations

The objective of this study was to establish the relationship of underline scores (UDLS), production traits, and conformation scores in Beefmaster cattle born between 1976 through 2008. Records provided by Beefmaster Breeders United (BBU) were analyzed. Certified classifiers approved by the BBU recorded scores. Sizes and shapes of the underlines differentiated the scores (1-4). A score of one was used to designate the least amount of navel flap or sheath and a score of four represents the maximum amount of naval flap or sheath accepted for registration in the BBU. In this study the relationship of the traits was determined …

Black-Capped Chickadee (Parus Atricapillus) Food Preference, Isabelle Gilbert

Thinking Matters Symposium

All animals must make decisions on where to find, select, capture, and eat food. These factors contribute to a species’ food preference, such as making decisions on what food to eat based on calories. Optimal foraging theory predicts how an animal behaves when searching for food, including optimization of food type, patch choice, time spent in patches, and movement. All animals also make decisions based on predation risk by avoiding predators and making trade-offs on time spent searching for, pursuing, and handling food. The objective of my study is to examine food preference of black-capped chickadees (Parus atricapillus). Birds may …

The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori

Theses and Dissertations

Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …
