Theses and Dissertations in Animal Science
A systems study evaluated the effects of an implant [25.7 mg estradiol (Compudose; Elanco Animal Health)] at two rates of gain (LOW: 0.45 kg/d and HIGH: 0.9 kg/d) applied during the winter backgrounding phase in drylot and winter grazing systems and its effects on subsequent phases of production. HIGH supplementation with an implant during the winter backgrounding phase in the drylot system yielded the greatest ending body weight (EBW) during the summer backgrounding phase (P = 0.04). LOW supplementation, without an implant, improved summer backgrounding average daily gain (ADG; P = 0.05) while achieving similar carcass adjusted final body …

Pharmacokinetics Of Cbd Supplementation In Horses: Single Dose Vs. Long-Term Feeding, Madilyn Adamchik
Honors College Theses
Research about supplemental feeding of cannabidiol (CBD) to horses is still in its early stages, but many horse owners are feeding CBD supplements for supposed benefits, including behavior and pain management. Cannabinoids work through the endocannabinoid system to modulate nervous and hormonal actions in the body, working to maintain a healthy homeostatic balance. Safety and efficacy have been tested for dosages of up to 500 mg of CBD per day for horses, but further research about the pharmacokinetics based on dosage amount and form of CBD are still needed. The objectives of this study were to evaluate the pharmacokinetics of …

The virus SARS-CoV-2 emerged in late 2019 and has gone on to spread throughout the global population. The virus is still the cause of a healthcare crisis two years after being identified. Viral infection in humans leads to the development of the disease COVID-19. A complex disease that can result in a wide variety of outcomes for infected individuals. In the majority of individuals, COVID-19 will manifest as either an asymptomatic disease state or a mild to moderate disease state that is resolved in approximately one week. In some infected patients COVID-19 will manifest with the rapid onset of severe …

Habitat Selection By Desert Carnivores: How Water, Intraguild Predation, And Prey Impact Animal Space Use, Nadine A. Pershyn
All Graduate Theses and Dissertations
Across North America large carnivores have lost nearly half of their historic range, creating openings for smaller (< 15 kg) carnivores to take over their ecological roles. Coyotes (Canis latrans) have seen a significant range expansion, including into arid deserts. It was believed that the addition of artificial water sources by humans allowed coyotes to expand into desert ecosystems where they were previously unable to survive. The kit fox (Vulpes macrotis) is a small, desert-adapted carnivore with declining populations that faces threats from coyotes of intraguild predation. This is when carnivores compete over the same prey, and the larger carnivore (intraguild predator) kills the smaller carnivore (intraguild …

Stress: An Adaptive Problem Common To Plant And Animal Science, Özlem Yilmaz
Animal Sentience
It is very hard to determine whether plants have “felt states,” but they do have specific states, such as stress, that depend on sensory input from their environment. Plants do not have neurons or brains, but they do have xylem and phloem, as well as many signalling molecules that are dynamically distributed in their bodies, enabling them to produce systemic responses to environmental stimuli. One common topic in plant and animal science that may or may not prove to involve sentience but that does involve the same molecules is stress.

A New Monotypic Genus And Species From China, Langxie Feti Gen. Et Sp. N. (Scorpiones: Buthidae), Victoria Tang, Qingquan Jia, Leonhard Liu
Euscorpius
A new monotypic genus, Langxie gen. n., is described from Xizang (Tibet), China. The new genus shares an important morphological character with Afrolychas Kovařík, 2019: absence of external accessory denticles (EADs) along the sixth row of median denticles (MDs) on the pedipalp movable finger. Langxie gen. n. is different from Afrolychas in the following aspects: loss of EAD near the proximally enlarged MD within each row (i. e., loss of all EAD on the movable finger; this also distinguishes the new genus from other related genera in the “(Ananteris + Isometrus)” clade (Štundlová et …

What Can Plant Science Learn From Animal Nervous Systems?, Luiz Pessoa
Animal Sentience
I welcome Segundo-Ortin & Calvo’s (2023) call for a rigorous science of plant behavior and physiology. My commentary addresses three points drawn from the literature on animal brains that could help elucidate the possibility of cognition and sentience in plants: (1) the presumed requirement of a centralized brain; (2) centralization of control versus heterarchical organization; and (3) connecting plant research with research on animal nervous systems.
Adaptive Plasticity Of Coloration In Response To Environmental Change,

Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield
Scholars Week
When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common. …

Questions About Sentience Are Not Scientific But Cultural, Yoram Gutfreund
Animal Sentience
Abstract: The findings of complex cognitive-like behaviours in plants are surprising and exciting. However, they do not provide a scientific reason for ascribing sentience to plants. The target article, in trying to provide evidence for sentience in plants, exposes the weakness of the science of animal consciousness in general. In this commentary, I try to explain why the scientific method is incapable of resolving the question of which organisms or systems are sentient.

Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger
Scholars Week
Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

MANTER: Journal of Parasite Biodiversity
The geographical ranges of many mammals and their associated parasites are dynamic. Comprehensive documentation of these communities over time provides a foundation for interpreting how changing environmental conditions, driven by accelerating climate change, other anthropogenic disturbances, and natural events, may influence host-parasite interactions. Fleas (Order Siphonaptera) are obligate, hematophagous parasites of birds and mammals with medical interest because of their role in transmitting pathogens. From 2016 to 2019, we sampled the small mammal and associated flea communities in El Malpais National Conservation Area (El Malpais) in Cibola County, New Mexico. Among 898 mammalian specimens, 925 fleas representing 29 species were …

Atrial Fibrillation (AF) is the most common cardiac arrythmia in adults with likely sex-specific risk factors. Female sex hormones may be important in modulating risk for atrial fibrillation. We hypothesize that pregnancy and progesterone (P4), a hormone found in high levels during pregnancy with abrupt withdrawal immediately after parturition, modulates AF susceptibility in female goats. Cardiac specific TGF-?1 transgenic female goats and age-matched wild-type (WT) female goats were utilized. Pacemakers were implanted in all animals for continuous arrhythmia monitoring and AF inducibility. AF inducibility was evaluated using 5 separate 10 s bursts of atrial pacing (160 - 200 ms). In …

Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette
Honors College Theses
Cannabidiol (CBD) is a substance that has been used in complementary medicine for many years. However, modern medicine has little knowledge of how this substance is utilized and metabolized in ruminant animals. Regulations on quality assurance and use in animals are lacking, and CBD supplementation in livestock is not approved. If CBD supplements can be shown to be safe and effective, detection in the animal will be important for determining regulation of use. A withdrawal period can then be established to allow time for deterioration of product to safe levels before livestock products enter human markets. This study sought to …
