Reduced body size and accelerated life cycle due to warming are considered major ecological responses to climate change with fitness costs at the individual level. Surprisingly, we know little about how relevant ecological factors can alter these life history trade‐offs and their consequences for individual fitness. Here, we show that food modulates temperature‐dependent effects on body size in the water flea Daphnia magna and interacts with temperature to affect life history parameters. We exposed 412 individuals to a factorial manipulation of food abundance and temperature, tracked each reproductive event, and took daily measurements of body size from each individual. High …

Clinical evidence is mounting that Zika virus can contribute to Guillain-Barré syndrome which causes temporary paralysis, yet the mechanism is unknown. We investigated the mechanism of temporary acute flaccid paralysis caused by Zika virus infection in aged interferon αβ-receptor knockout mice used for their susceptibility to infection. Twenty-five to thirty-five percent of mice infected subcutaneously with Zika virus developed motor deficits including acute flaccid paralysis that peaked 8-10 days after viral challenge. These mice recovered within a week. Despite Zika virus infection in the spinal cord, motor neurons were not destroyed. We examined ultrastructures of motor neurons and synapses by …

Exposure of lupus-prone female NZBWF1 mice to respirable crystalline silica (cSiO2), a known human autoimmune trigger, initiates loss of tolerance, rapid progression of autoimmunity, and early onset of glomerulonephritis. We have previously demonstrated that dietary supplementation with the ω-3 polyunsaturated fatty acid docosahexaenoic acid (DHA) suppresses autoimmune pathogenesis and nephritis in this unique model of lupus flaring. In this report, we utilized tissues from prior studies to test the hypothesis that DHA consumption interferes with upregulation of critical genes associated with cSiO2-triggered murine lupus. A NanoString nCounter platform targeting 770 immune-related genes was used to assess …
Evaluation Of A Proprietary Slow-Release Oxytocin Therapy And Return Of The Luteolytic Mechanism In Mares, Brendan Andrew Sarnecky
Evaluation Of A Proprietary Slow-Release Oxytocin Therapy And Return Of The Luteolytic Mechanism In Mares, Brendan Andrew Sarnecky
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Prolonging function of the corpus luteum (CL) is a method of suppressing estrus that maintains secretion of endogenous progesterone to keep mares out of heat naturally. The use of oxytocin to prolong CL function is becoming more popular. In these therapies, upregulation of cyclooxygenase-2 is inhibited, which impairs prostaglandin F2α ( PGF2α) production. Intramuscular (IM) administration of 60 IU of oxytocin once daily from 7 to 14 days after ovulation is currently the most common treatment protocol. Although that protocol is efficacious in ≥70% of treated mares, the need for daily administration is a drawback to its use. A proprietary …

- Zoonotic pathogens can harm human health and well‐being directly or by impacting livestock. Pathogens that spillover from wildlife can also impair conservation efforts if humans perceive wildlife as pests. Brucellosis, caused by the bacterium Brucella abortus, circulates in elk and bison herds of the Greater Yellowstone Ecosystem and poses a risk to cattle and humans. Our goal was to understand the relative effects of climatic drivers, host demography and management control programmes on disease dynamics.
- Using >20 years of serologic, demographic and environmental data on brucellosis in elk, we built stochastic compartmental models to assess the influences of climate forcing, …
The Tail Wagging The Dog: Positive Attitude Towards Livestock Guarding Dogs Do Not Mitigate Pastoralists’ Opinions Of Wolves Or Grizzly Bears, Daniel Kinka, Julie K. Young
The Tail Wagging The Dog: Positive Attitude Towards Livestock Guarding Dogs Do Not Mitigate Pastoralists’ Opinions Of Wolves Or Grizzly Bears, Daniel Kinka, Julie K. Young
Wildland Resources Faculty Publications
While the re-establishment of grizzly bears (Ursus arctos) and wolves (Canis lupus) in the American West marks a success for conservation, it has been contentious among pastoralists. Coincidentally, livestock guarding dogs (LGDs; Canis familiaris) have been widely adopted by producers of domestic sheep (Ovis aries) in the United States to mitigate livestock depredation by wild carnivores. We surveyed pastoralists to measure how experience with and attitudes towards LGDs related to attitudes towards livestock predators, and found positive responses regarding LGDs and negative responses regarding wolves and grizzly bears. The more respondents agreed that …

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral hemorrhagic fever (VHF) endemic to China, South Korea, Japan, and Vietnam. Here we characterize the pathogenesis and natural history of disease in IFNAR-/- mice challenged with the HB29 strain of SFTS virus (SFTSV) and demonstrate hallmark features of VHF such as vascular leak and high concentrations of proinflammatory cytokines in blood and tissues. Treatment with FX06, a natural plasmin digest product of fibrin in clinical development as a treatment for vascular leak, reduced vascular permeability associated with SFTSV infection but did not significantly improve survival outcome. Further studies are …

The TORC2 gene is a member of the transducer of the regulated cyclic adenosine monophosphate (cAMP) response element binding protein gene family, which plays a key role in metabolism and adipogenesis. In the present study, we confirmed the role of TORC2 in bovine preadipocyte proliferation through cell cycle staining flow cytometry, cell counting assay, 5-ethynyl-20 -deoxyuridine staining (EdU), and mRNA and protein expression analysis of proliferation-related marker genes. In addition, Oil red O staining analysis, immunofluorescence of adiponectin, mRNA and protein level expression of lipid related marker genes confirmed the role of TORC2 in the regulation of bovine adipocyte differentiation. …
Home Range And Habitat Use Of West Virginia Canis Latrans (Coyote), Lauren L. Mastro, Dana J. Morin, Eric M. Gese
Home Range And Habitat Use Of West Virginia Canis Latrans (Coyote), Lauren L. Mastro, Dana J. Morin, Eric M. Gese
Wildland Resources Faculty Publications
Canis latrans (Coyote) has undergone a range expansion in the United States over the last century. As a highly opportunistic species, its home range and habitat use changes with ecological context. Coyotes were first reported in West Virginia in 1950 but were not commonly observed until the 1990s, and there is scant information on Coyotes in the region. We used telemetry data from 8 radiocollared Coyotes in West Virginia to estimate home-range size and third-order habitat selection. Home-range areas (95% utilization distributions; UDs) varied from 5.22 to 27.79 km2 (mean = 12.48 ± 2.61 km2), with highly …
Epigenetic Reprogramming, Apoptosis, And Developmental Competence In Cloned Embryos, Laura A. Moley
Epigenetic Reprogramming, Apoptosis, And Developmental Competence In Cloned Embryos, Laura A. Moley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cloning through somatic cell nuclear transfer (SCNT) remains highly inefficient twenty years after the first demonstration of the technology with the birth of Dolly. By increasing efficiency by selecting the embryos early in development that are most likely to succeed following transfer into a surrogate mother, the technology could be more routinely utilized to enhance animal agriculture production. SCNT is believed to be highly inefficient as a result of incorrect DNA methylation and gene expression that are accumulated because of the SCNT technique. We proposed the use of a non-toxic, non-invasive detector of cell death, to quantitatively assess embryo competency …
The Effect Of Lactation And Energy Status On Gene Expression In The Main Reproductive Tissues Of Lactating Dairy Cattle, Sameer M. Alhojaily
The Effect Of Lactation And Energy Status On Gene Expression In The Main Reproductive Tissues Of Lactating Dairy Cattle, Sameer M. Alhojaily
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Modern high-yielding dairy cows are currently producing far more milk than their ancestors due to a prolonged and intensive genetic selection for milk production trait accompanied by the revolutionary improvement in technology, management, and nutrition. On the other hand, a noticeable decline in fertility and reproductive performance was undeniably consistent with the increase in milk yield. This decline in fertility and reproductive performance are recognized worldwide and well documented in several studies. Dairy cows typically experience a period of energy deficit during the first few months of lactation due to the rapid increase in milk production and limited feed intake. …

The Western dietary pattern can alter the gut microbiome and cause obesity and metabolic disorders. To examine the interactions between diet, the microbiome, and obesity, we transplanted gut microbiota from lean or obese human donors into mice fed one of three diets for 22 weeks: (1) a control AIN93G diet; (2) the total Western diet (TWD), which mimics the American diet; or (3) a 45% high-fat diet-induced obesity (DIO) diet. We hypothesized that a fecal microbiome transfer (FMT) from obese donors would lead to an obese phenotype and aberrant glucose metabolism in recipient mice that would be exacerbated by consumption …

Zika virus (ZIKV) is an arboviral infection that has been shown to be sexually transmitted. The study outlined herein aims to determine if accessory sex glands and epididymal epithelial cells are sources of viral persistence in subacute and chronic ZIKV infection, and if infection of these organs is important in sexual transmission during long-term (chronic) infection. Male interferon type I receptor knockout (Ifnar−/−) mice were challenged with ZIKV and reproductive tissues were harvested 14 and 35 days post infection (DPI) for inoculation studies and 14, 35 and 70 DPI for histopathology. Artificial insemination fluid derived from epididymal …

A seven-year-old spayed female Labrador retriever presented for necropsy following an acute history of thrombocytopenia, anemia, leukocytosis and abdominal effusion. A 2 × 3 × 10 cm, cylindrical to tubular, mottled red-to-tan mass extended from the caudal pelvic cavity caudally and ventrally under the dermis along the caudal aspect of the left pelvic limb adjacent to the semimembranosus and semitendinosus musculature. Histologic examination of the mass revealed a singular central lumen lined by urothelium that multifocally transitioned into non-keratinizing, stratified squamous epithelium associated with few hair follicles and sweat glands. The lumen was surrounded by a dense collagenous stroma containing …

Development of antiviral drug resistance is a continuous concern for viruses with high mutation rates such as influenza. The use of antiviral drugs targeting host proteins required for viral replication is less likely to result in the selection of resistant viruses than treating with direct-acting antivirals. The iminosugar UV-4B is a host-targeted glucomimetic that inhibits endoplasmic reticulum α-glucosidase I and II enzymes resulting in improper glycosylation and misfolding of viral glycoproteins. UV-4B has broad-spectrum antiviral activity against diverse viruses including dengue and influenza. To examine the ability of influenza virus to develop resistance against UV-4B, mouse-adapted influenza virus was passaged …

In 2008, a consortium led by the Agricultural Research Service (ARS) and the National Institute for Food and Agriculture (NIFA) published the “Blueprint for USDA Efforts in Agricultural Animal Genomics 2008–2017,” which served as a guiding document for research and funding in animal genomics. In the decade that followed, many of the goals set forth in the blueprint were accomplished. However, several other goals require further research. In addition, new topics not covered in the original blueprint, which are the result of emerging technologies, require exploration. To develop a new, updated blueprint, ARS and NIFA, along with scientists in the …

Development Of Mouse Models For Respiratory And Neurological Disease Caused By Enterovirus D68 And Evaluation Of Antiviral Therapies, Brett L. Hurst
Development Of Mouse Models For Respiratory And Neurological Disease Caused By Enterovirus D68 And Evaluation Of Antiviral Therapies, Brett L. Hurst
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Enterovirus D68 (EV-D68) is a virus that normally causes disease in children. While this virus typically causes a respiratory infection, in 2014, a large outbreak of the virus was associated with patients that had paralysis of the arms or legs. Even though the virus was discovered in 1962, little was known about the life cycle of the virus or its ability to cause disease. An animal model of disease was needed to understand how the virus causes disease and to develop antiviral compounds to target the virus life cycle.
We adapted the virus by serial-passage in lung tissues from mice …

Ruminal Protection And Intestinal Availability Of Rumen-Protected Methionine And Lysine In Lactating Dairy Cows, Sara Menchu
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Rumen protected Methionine (MET) and Lysine (LYS) are critical for milk protein synthesis in dairy cows. N-acetyl-L-methionine (NALM) is a MET derivative that consists of L-Met protected with an acetyl group that is attached to the α-amino group.N-acetyl-L-lysine (NALL) is a LYS derivative that is similarly protected. The objectives of these studies were to quantify the gastrointestinal availability of NALM and NALL. Three experiments were run as 3 × 3 Latin square using 3 second lactation Holstein cows that have been fitted with cannulas in the rumen and duodenum. The cows …

Male Reproductive Infection And Sexual Transmission Of Zika Virus In An Immunocompromised Mouse Model, Chad S. Clancy
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Zika virus (ZIKV) is a sexually transmitted viral infection most frequently transmitted by mosquitoes. The source of infectious virions in the male reproductive tract has yet to be elucidated. The goals of the studies included developing and characterizing two mouse models for reproductive transmission studies and demonstration of sexual transmission of virus via artificial insemination. The mouse strains used in the study lacked receptors to interferon molecules, key signaling proteins of the host immune response. Inflammation severity was assessed during acute disease, 5-11 days after infection using a novel histopathology grading system. ZIKV proteins and genome were initially detected in …

Evaluation Of Casein Hydrolysate As An Alternative Dry-Off Treatment And Milk Quality Management Tool In Dairy Cows, Justine Elena Britten
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Mastitis, an infection of the mammary gland, is the most common and expensive animal health problem for the dairy industry and affects every dairy farm to some degree. This disease complex is painful for dairy cows, increases the on-farm use of antibiotics, presents a threat to milk quality and is a waste of time, money and milk production. Each year, the dairy industry loses as much as a billion dollars to mastitis.
Many cows will experience mastitis at least once during a lactation cycle and some animals will develop recurring mastitis episodes in a single mammary quarter. These mastitic quarters …
Young Germ Cell Depleted Ovaries In Post-Reproductive Mice And Its Effects On Immune Function, Mckenna Walters
Young Germ Cell Depleted Ovaries In Post-Reproductive Mice And Its Effects On Immune Function, Mckenna Walters
Undergraduate Honors Capstone Projects
It has previously been shown that young, cycling ovarian transplantation in aged female mice increased the general health and life span in regard to their post-reproductive health. It has further been hypothesized that this enhancement of health is directly influenced by the ovarian somatic cells. To address this hypothesis, transplants of young germ cell depleted and germ cell containing ovaries were performed on female mice. The purpose of this study is to continue to discern the reproductive influence on aging health, specifically in the area of immunological well-being. Control group mice were separated by age and treatment mice were subsequently …
Analyzing Fear Free Veterinary Practices And Their Effectiveness In Managing Client And Patient Fear, Anxiety, And Stress, And The Profitability Of These Techniques, Heather Hamblin
Undergraduate Honors Capstone Projects
Fear-Free veterinary techniques are a new approach to caring for patients and clients in the veterinary clinic that have gained a great deal of popularity and traction. However, many veterinary professionals are left to question whether the utilization of these practices is resulting in a big enough change in client and patient stress levels to make it worth implementing these methods. This research looks into the views of veterinarians and clients on the effectiveness of these practices, and the competitive advantage of having a fear-free certified clinic from a business point of view.

Dietary interventions with probiotic lactic acid bacteria (LAB) and prebiotics, complex dietary fibers that promote LAB growth, may favorably shift the gut microbiome to reduce colorectal cancer risk. Our primary hypothesis was that the LAB strains NCFM Lactobacillus acidophilus and HNO 19 Bifidobacterium lactis would thrive in the presence of agave, green banana, black raspberry, baobab fruit, or pomegranate peel whole food powders by fermenting their oligosaccharide (OS) components into lactic acid end products. LAB strains were cultured in media with no carbohydrate, purified OS, or one of the whole food powders. LAB strains cultured with agave appeared to grow …

Percussive Behavior In The Southern Resident Killer Whale (Orcinus Orca) Population At Lime Kiln Point State Park, Rylee Jensen
Undergraduate Honors Capstone Projects
The endangered Southern Resident Killer Whale (Orcinus orca, SRKW) is an iconic species in the Pacific Northwest. Although many ecological aspects of this population have been studied, including population dynamics, genealogy, diet, and habitat-use patterns, why SRKW perform above-surface "percussive" behavior such as breaching, cartwheeling, pectoral fin slapping, tail lobbing, and dorsal fin slapping remains unclear. In the present study, a) individual percussive behavioral data was recorded during the summer of 2016 to evaluate trends by age and sex class, and b) an existing long-term data set on SRKW was analyzed to compare the relationship between the seasonal …

Menopause is associated with a decline in overall health in women. One health aspect impacted is glucose metabolism. As women experience menopause, their metabolism declines dramatically. The current study addressed the influence of ovarian somatic cells on the improvement of metabolic health through transplantations of young, germ cell-depleted ovaries. The purpose of this study is to expand the understanding of female reproductive health on metabolism. Control mice were grouped by age and treatment mice were age-matched. Treatment mice were placed into one of three groups: 1) mice received germ cell-depleted ovaries, 2) mice received germ cell-containing ovaries, and 3) mice …
A Review Of Osteoarthritis, Madelin Brooke Session
A Review Of Osteoarthritis, Madelin Brooke Session
Undergraduate Honors Capstone Projects
Osteoarthritis is a degenerative joint disease which plagues many older animals and humans. It is a disease that is characterized by the degeneration of joint cartilage, inflammation, as well as chronic pain and stiffness that results from this disorder. Unfortunately, most of the treatments for this painful and chronic disease mostly involve pain management and temporary relief strategies. These strategies usually include pain medication, non-steroidal anti-inflammatory drugs, injectable lubricants, as well as surgical techniques. However, because these treatments are just temporary fixes meant for pain management and to improve quality of life they must continue throughout the remainder of the …
