Effects Of Intensive Exercise On The Blood Chemistry Of Fighting Bulls In Southern Thailand, Siriwat Wasiksiri, Pratthana Yongsakulchai, Wichaya Thongtako, Paradorn Muangnil, Teepakorn Adulkasem

The Thai Journal of Veterinary Medicine

Bullfighting is a cultural activity in southern Thailand. Bulls walk and undergo intensive exercise before competition. In the arena, winners are determined by their opponents' surrender, so bulls do not die after fighting. However, there are very few studies on organ injuries in living bulls during these activities. This study compared the effects of walking and intensive exercise on complete blood count (CBC) and blood chemistry. Blood parameters of 14 Thai fighting bulls aged over 6 years, regularly trained for walking and intensive exercise, were measured and analyzed using a paired t-test or Wilcoxon signed-rank test. Eosinophils decreased significantly after …

A Series Of Investigations On The L. Cornutus Host System And Bivesiculid Sp. Cercariae, Briana K. Zaffiro

All HCAS Student Capstones, Theses, and Dissertations

Rising global temperatures are likely modulating parasite-host interactions, yet the direction and magnitude of these changes remain uncertain. Rarely are these interactions viewed from both a host and parasite perspective. Using both CT_max, or Critical Thermal Maximum, and Clark-type polarographic oxygen microelectrodes, the physiological metabolic effects are investigated. CT_max is examined in Common Shiners, Luxilis cornutus, and is shown to be modulated by parasitism: uninfected fish had the highest CT_max average of 37.0°C, whereas heavily infected fish had decreased CT_max averaging 35°C. Prior to the parasite metabolic investigation, a suitable medium was determined, as …

Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Honors Theses

This study explores how the tempo of music, measured in beats per minute (BPM), affects dogs' heart rate and oxytocin levels, adding to past research that shows that music affects physiological and behavioral states in dogs. Being able to understand these effects holds practical implications for improving overall well-being in canines in environments such as homes, shelters, and clinical environments. Using a within-subjects design, the dogs were exposed to slow and fast versions of one instrumental track, along with a white noise baseline condition before each randomized condition. Heart rate was recorded continuously throughout the session, and oxytocin saliva samples …

The Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Poster Presentations

Music is a universal component of human culture that has been demonstrated influencing emotional, cognitive, and physiological responses, specifically heart rate and hormonal responses (Mehr et al., 2019; Trappe, 2012). Recently, this research has expended to explore how music may affect non-human animals, particularly dogs, due to their roles as therapy animals, service animals, and human companions (Lindig et al., 2020; Gee et al., 2021). Being able to understand how music influences canine stress and relaxation hold important applications in environments such as shelters, veterinary clinics, and at home. One important feature of music is tempo, or beats per minute …

Continuous Light And Pinealectomy: Two Models Of Melatonin Deficiency Revealing Distinct Interactions With Vitamin D Deficiency On Blood Parameters, Rebaz Sedeeq Shekh, Ismail Mustafa Maulood

Polytechnic Journal

Modern lifestyles reduce sunlight exposure and increase artificial light at night, potentially promoting vitamin D deficiency (VDD) and melatonin (MEL) suppression. The two hormones regulate immunity, erythropoiesis, and platelet (PLT) indices, but their combined hematological effects are not well characterized. We investigated the independent and combined effects of VDD and MEL deficiency on leukocyte profiles, erythrocyte indices, and PLT parameters in albino rats using two 12-week models (n = 8/group): continuous light (CL)-induced MEL suppression (Control, CL, VDD, and CL + VDD) and pinealectomy (Px)-induced MEL deficiency (Sham. Px, VDD, Px + VDD). Complete blood counts (CBCs) and inflammation-related ratios …

Hot Cities, Cool Lizards: Do College Campuses Create Urban Oases For Wildlife?, Ethan Heck, Javier Monzon Phd

Seaver College Research And Scholarly Achievement Symposium

Urban wildlife may experience stress due to the Urban Heat Island Effect. On the other hand, urban wildlife may experience relief, especially in arid ecosystems, due to the Urban Oasis Effect. The objective of this study was to test whether college campuses in southern California act as heat islands or oases for wildlife. We analyzed how temperature and water availability of microhabitats relate to the physiology of a widespread and common cold-blooded animal, the Western Fence Lizard (Sceloporus occidentalis). We logged environmental conditions in lizard hotspots at 11 university campuses across southern California and measured the hydration of lizards at …

Muscular Degeneration In Caenorhabditis Elegans By Microplastic And Chemical Exposure Through Locomotion Analysis, Juan Pablo Olvera Rodriguez, Angelica Cue-Leon, David Mares

Posters - 2026

We use Caenorhabditis elegans (C. elegans) as a model organism to investigate the effects of microplastic and chemical exposure on muscle structure and function.

• Microplastics (MP) are pieces of plastic less than 5 μm, and Nanoplastics (NP) are less than 1 μm. Microplastics are man-made pollutants and have been found in the environment and in the food and water sources, including drinks from plastic bottles (Hu, 2020). • Our work relates environmental contamination to potential biological consequences at the muscular level, providing insight into how pollutants may contribute to degenerative damage.

• Polystyrene (PS) MPs alone and combined with …

Health Indicators Worsened By Moderate-Intensity Heat Stress Are Only Partially Recovered By Ω-3 Polyunsaturated Fatty Acid Supplementation, Melanie R. White, Shelley A. Curry, Ashley A. Hahn, Jessica L. Petersen, Ty B. Schmidt, Dustin T. Yates

Nebraska Beef Cattle Reports

Summary with Implications

Heat stress throughout the summer and into the fall is a persistent hurdle for growing and finishing cattle in Nebraska. Minimizing the impact of heat on growth and well-being of cattle is critical to the productivity and profitability of beef production. This project aimed to evaluate the effect of an anti-inflammatory dietary supplement, ω-3 polyunsaturated fatty acids (ω-3 PUFA), on physiological indicators of stress during a 4-day moderate-intensity heat challenge. Heat stress elevated core body temperature and respiration rates as expected but did not impact circulating inflammatory biomarkers. Heart rate variability measurements indicative of adrenergic stress and …

Modulation Of Heat Stress Responses In Cattle Supplemented With Dietary Ω-3 Polyunsaturated Fatty Acids, Shelley A. Curry, Melanie R. White, Ashley A. Hahn, Dustin T. Yates

Nebraska Beef Cattle Reports

Summary with Implications

Heat stress in beef cattle triggers physiological and metabolic disturbances that compromise performance, health, and welfare. In this study, Red Angus heifers exposed to heat stress for 5 days exhibited elevated body temperatures, increased heart and respiration rates, and altered hematological and acid–base parameters. A commercial ω-3 polyunsaturated fatty acid (PUFA) dietary supplement failed to improve heat stress-reduced ribeye area or red blood cell parameters but did resolve the reduction in blood chloride concentrations, which is consistent with restoration of electrolyte balance and hydration under heat stressed conditions. These results indicate that ω-3 PUFA supplementation offers some …

Systematics Of Disk-Winged Bats (Thyroptera), Courtney L. Klumpp

Capstone Showcase

This thesis investigates the evolutionary relationships among disk-winged bats in the genus Thyroptera, a small group of Neotropical bats known for the adhesive suction disks on their wings and feet that allow them to roost inside tightly rolled leaves. The distinctive morphology and behavior of these bats have not been extensively documented, and their phylogenetic relationships remain only partially resolved. The goal of this research is to better understand how these species are related to one another and to determine whether the five recognized species of Thyroptera form a single monophyletic group. To address this question, morphological and genetic …

Measuring Welfare Of Wild Tarantulas During Field Surveys Using Heart Rate, Tim Angelo Artiaga Lopez, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Tarantulas (Theraposidae) are predatory arachnids that can help control populations of herbivorous arthropods. We have been monitoring populations of the Missouri brown tarantula (Aphonopelma hentzi) in Missouri glades for three seasons and have questions about their welfare during these surveys. Unlike mammals, arthropods are not extensively researched and there are only a few known facts about measuring their welfare. Managing stress for wild animals during field surveys is important for reducing the potential negative impacts of research. In mammals, increased heart rate is positively correlated with negative stress and eustress. Using the same logic, we hypothesized that heart rate could …
