A Survey Of Dairy-Goat Keeping In Zanzibar, Tiffanie Stone, Charles A. Francis, L. O. Eik

Department of Agronomy and Horticulture: Faculty Publications

Dairy goats with improved genetics for milk production were recently introduced onto small-scale farms in Zanzibar through governmental and non-governmental projects. These projects were meant to support small-scale farmers by improving both income and household nutrition through milk production. No follow up had been conducted to understand what effects dairy goat keeping had on these small-scale farms, or how they could be improved. A survey of 193 dairy goat farmers in Zanzibar was conducted, including 30% and 60% of all dairy goat farmers on Unguja and Pemba, the two largest islands, respectively. The objective was to understand the impact keeping …

Anaplasmosis In Dogs, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Anaplasmosis is a tick-borne disease that occurs in dogs, caused by either the bacteria Anaplasma platys or A. phagocytophila. Illness caused by A. platys and other tick-borne parasites such as Babesia canis vogeli may be colloquially referred to as ‘tick fever’. The disease is thought to be transmitted by the brown dog tick (Rhipicephalus sanguineus) and possibly lice.

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt

Honors Thesis

The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with …

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

Presence Of Dirofilaria Immitis In Mosquitoes In Southeastern Georgia, Angelica C. Tumminello

Honors College Theses

Canine heartworm disease is caused by the filarial nematode Dirofilaria immitis, which is transmitted by at least 25 known species of mosquito vectors. This study sought to understand which species of mosquitoes are present in Bulloch County, Georgia, and which species are transmitting canine heartworm disease. This study also investigated whether particular canine demographics correlated with a greater risk of heartworm disease. Surveillance of mosquitoes was conducted in known heartworm-positive canine locations using traditional gravid trapping and vacuum sampling. Mosquito samples were frozen until deemed inactive, then identified by species and sex. The mosquitoes were then either dissected under …

The Effect Of Staphylococcus Aureus Exposure On White-Tailed Deer Trabecular Bone Stiffness And Yield, Emily Brooke Long

Graduate Theses

Osteomyelitis is an infection of the bone or bone marrow caused by the infiltration of bacteria, resulting in destructive inflammation, bone necrosis and abnormal bone remolding. With a growing number of osteomyelitis diagnoses, many of which are linked to Staphylococcus aureus (S. aureus), it is imperative to understand the pathology of S. aureus in relation to bone to provide better diagnostics and patient care. While the cellular mechanisms of S. aureus and osteomyelitis have been studied, little information exists on the biomechanical effects of such infections. We postulated that exposure to S. aureus for 72 hours would significantly decrease both …

Differences In Learning And Gene Expression In Brains Of Male And Female Bicyclus Anynana, Gabrielle Agcaoili

Biological Sciences Undergraduate Honors Theses

One way to understand the variation in the behavior of animals is by looking at the genes involved. We were particularly interested in behavioral differences between the sexes. How might these differences be manifested in the brain? This study worked to answer this question by using male and female butterflies of the species Bicyclus anynana, examining what is going on in the brains of males and females as they learned from a social exposure. We focused in on how sex plays a role in behavior and learning; it has been seen that males and females respond to the same social …

Pilot Testing A Qualitative Methodology To Evaluate The Perceived Benefits And Stressors Of Sole-Dog Ownership In Full-Time College Students, Emma Williams

Animal Science Undergraduate Honors Theses

The number of individuals acquiring pets is continually increasing, with 71.5% of Americans owning a pet in 2012. Companion animals are a huge source of benefits but owning them can also come with several stressors. However, little research has been conducted on the negative aspects of dog ownership. This pilot test evaluates the perceived stressors and benefits of sole dog ownership in full-time college students. The pilot aimed to hold three focus groups from which qualitative thematic data were collected and quantitative were collected from a demographic survey of participants. Participants were asked a series of questions about sole dog …

Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones

Animal Science Undergraduate Honors Theses

Abstract

Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and …

Usu Equine-Assisted Activities And Therapies Facilities Designed Master Plan, Lindsie C. Smith

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Equine-Assisted Activities and Therapies (EAAT) is recognized as a therapeutic approach for persons with disabilities. The USU Animal, Dairy, and Veterinary Sciences Department provides EAAT instruction and services; however, they do not have the appropriate facilities to model best-practices in the delivery of these services. This design research entailed the development of a phased masterplan to support the instruction and delivery of equine-assisted activities and therapies in an innovative and accessible environment that supports animal-assisted intervention and natural equine behaviors.

The methodology used to approach the master plan design was derived from Norman K. Booth’s (1990) design process, as described …

The Effects Of Total Body Proton Irradiation On Mouse Myometrium, Lillith Bulawa

Undergraduate Honors Theses

The boundaries of human space exploration continue to expand with new technology and discoveries making it even more important to investigate the effects of space on biological systems. Although humans have explored space in small increments, reproductive studies must be conducted to determine if stable short- or long-term residences for humans can exist in space. This study explored the effects of whole-body proton radiation on uterine smooth muscle known as the myometrium. Two types of mice utilized in this study were C57BL/6 and B6.129S6Cybbtm1Din/J NOX2 knockout mice. C57BL/6 mice are standard laboratory mice that were used to represent the wildtype …

The Role Of Dopamine In Decision Making Processes In Drosophila Melanogaster, Michelle C. Bowers

Undergraduate Honors Theses

Understanding the neural processes that mediate decision making is a relatively new field of investigation in the scientific community. With the ultimate goal of understanding how humans decide between one path and another, simpler models such as Drosophila Melanogaster, the common fruit fly, are often utilized as a way of determining the neural circuits involved in these decision-making processes. One of the most important decisions flies make is the decision of where to lay their eggs (oviposit). Choosing the proper substrate upon which to lay eggs is a crucial decision that can ultimately impact their fecundity. This paper investigates the …

The Wild Diamond Diaries: Healing Alongside America's Wild Horses, Megan Emily

All NMU Master's Theses

To some, America’s free-roaming Mustangs and burros symbolize liberty and beauty. To others, these equines are feral at best, invasive at worst. They have a reputation for being useless, destructive, and untrainable. Yet my childhood horse—gifted to my family when I was three—was a gentled Mustang, W.D. Through W.D., I first encountered these horses’ kind dispositions, composure, and hardiness. After my younger sister died in a riding accident with another horse, my parents rehomed W.D. The devastating loss of both my sister and horse sparked my lifelong interest in Mustangs’ lives in the wild and journey into domestication, especially via …

Chronoecology Of A Cave-Dwelling Orb-Weaver Spider, Meta Ovalis (Araneae: Tetragnathidae), Rebecca Steele

Electronic Theses and Dissertations

Circadian clocks enable coordination of essential biological and metabolic processes in relation to the 24-hour light cycle. However, there are many habitats that are not subject to this light cycle, such as the deep sea, arctic regions, and cave systems. This study analyzes the circadian pattern of isolated populations of a subterranean spider, Meta ovalis from two Tennessee caves and five Indiana caves. Locomotor activity was recorded with TriKinetics LAM50 Locomotor Activity Monitor under a 12-hour light (L), 12-hour dark (D) (LD 12:12) cycle preceding total darkness (DD). Significant differences were found within and among populations found in Tennessee cave …

Impact Of Storage Temperature On Viability Of Microbial Inoculum For Estimating In Vitro Equine Digestibility, Delaney Brenne O'Donnell

Graduate Theses/Dissertations

This study evaluated the effect of storage temperature of equine fecal material on the viability of microbial inoculum used for in vitro equine digestibility trials. Fecal material was stored at four storage temperatures of 39°C for 15 minutes (control), 22°C for 6h, 3°C for 6h, and -18°C for 24h. Stored fecal material was used to form microbial inoculum for use in an Ankom Daisy II Incubator. Six different forage samples were digested in the Ankom Daisy II Incubator to evaluate interactions between storage condition of microbial inoculum and chemical composition of digested forage samples. After determination of dry matter digestibility …

Equine Massage Following Intense Work: Effects On Plasma Creatine Kinase, Brittany Pilat

Undergraduate Honors Thesis Projects

Horses are elite athletes, and many of them receive specialized care to keep them operating at their highest potential. Alternative modalities of healing- such as equine massage- have begun to grow in the equine world due to many perceived benefits. Equine massage is thought to decrease inflammation and reduce muscle tension and soreness. The aim of this study was to observe the effect of equine massage on creatine kinase (CK) levels in the blood following intense work. A total of 12 horses were randomly assigned to either the control group (n=6) or the test group (n=6). All horses were exercised …

The Effects Of Phosphate On Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Lexy Polivanov, Dennis Ferraro

UCARE: Research Products

This study seeks examine the effects of elevated phosphate levels on the larval stage of the Western Barred Tiger Salamander (Ambystoma mavortium). Hypothesis: Additional phosphate in the water will cause the larval salamanders to have a slower metamorphosis rate than the control group with no additional phosphates. This hypothesis is based off of research that showed that additional nitrogen in the water caused a slower growth rate in the Western Barred Tiger Salamander (Ambystoma mavortium) (Griffis-Kyle, 2007).

The hypothesis was rejected. The dates the larvae morphed alternated between treatment and control. The treatment metamorphosis was not …

Environmental Factors' Effects On Eastern Gray Squirrel (Sciurus Carolinensis) Infant Populations And Health, Jenny Mcfarland

Undergraduate Honors Thesis Projects

Ecosystem factors, both biotic and abiotic, impact all animal species. Temperature, rainfall, daylight, windspeed, mast production, competition and predation are integral to the ecosystem and thus affect the survival and overall wellbeing of the population. Eastern gray squirrel (Sciurus carolinensis) infant intakes at Ohio Wildlife Center followed a pattern of more infants in the fall than in the spring, differing from the usual observation that more infants are born in the spring. Ecosystem factors were compared to monthly and annual intakes to see what influenced intake date, admittance condition and survivability rate of the Eastern gray squirrel infants. The results …

Effect Of Calcium Supplement On Eyesight Of Western Tiger Salamanders, Abigail Horner, Dennis Ferraro

UCARE: Research Products

There has been some discussion in herpetoculture about adding calcium supplements to the diets of salamanders. Adding calcium supplements to a salamander’s diet has been indicated to contribute to blindness. Calcium supplements are usually given to reptiles and amphibians to prevent dietary deficiencies, particularly metabolic bone disease. The link between lack of calcium and metabolic bone disease is well established in reptiles, but is lacking significant research with regards to amphibians. Within the eye of a salamander, there are calcium channels that mediate photosynthetic rods in the absence of light. With a calcium rich diet, it is believed that these …

Bodyweight Management And Relationship To Health In The Horse (Equus Caballus), Beverly Ann Gartland

Masters Theses & Specialist Projects

The health of the horse is of interest to animal caretakers. Horses that fall within a prescribed range of bodyweight and body condition may be healthier than horses that are lower or higher. Two studies were conducted related to body weight and condition of the horse. The first study examined if restricting the amount of space available for horses to graze could reduce bodyweight without having a strong impact on time budgets of the horse or removing horses from pasture. This method was determined to be effective in preventing weight gain, although there was an increase in grazing behavior displayed …

Grackles, Michael J. Bodenchuk, David L. Bergman

Wildlife Damage Management Technical Series

Numbering in the tens of millions of birds, grackle populations in North America can cause a variety of conflicts with people. Grackles eat agricultural crops and livestock feed, damage property, spread pathogens, and collide with aircraft. Their large roosts can be a nuisance in urban and suburban areas. A combination of dispersal techniques, exclusion, and lethal removal may help to reduce grackle damage.

Grackles adapt easily to human-dominated environments, and exploit human food and other features of human landscapes. Thus, an integrated damage management approach to grackle damage focuses on reducing and eliminating the damage, rather than simply controlling grackle …

The Effect Of Slow-Feeding Hay Nets On Post-Prandial Equine Salivary Cortisol Levels, Grace Simpson

Undergraduate Honors Thesis Projects

Throughout its evolution, the Equus caballus, or horse, developed a physiological response to environmental alterations involving the synthesis and release of cortisol from the hypothalamic-pituitary-adrenal axis, to regulate blood glucose levels, vascular tone and hormone release throughout the body (Ambrojo et al., 2018). With a hypothesis that changing a horse’s feeding method can alter salivary cortisol levels, the aim of this research project was to determine if feeding forage to horses in slow-feeding haynets would significantly reduce acute cortisol salivary level fluctuations, which would be valuable to minimize horses’ stress and increase overall welfare. Two feeding methods …

The Effects Of Phosphate On The Metamorphosis Of Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Lexy Polivanov

Honors Program: Senior Projects (Public)

This investigation will collect data to assist in determining if elevated aquatic phosphate levels affects the metamorphosis rate of larval western barred tiger salamanders (Ambystoma mavortium). Monoammonium phosphate fertilizers are being used on crops in Nebraska (NDA, 2017). This area lines up with the area the western barred tiger salamanders are disappearing from (Damme, 2018). Monoammonium phosphate is made up of nitrogen and phosphate. There have been several studies showing how nitrogen is harmful to amphibians such as this salamander (Griffis-Kyle, 2007) (Griffis-Kyle & Richtie, 2007), but there have not been many showing how phosphate affects amphibian’s metamorphosis …

The Role Of Dislodgement In The Territorial Ecology Of The Owl Limpet, Lottia Gigantea, Ryan T. Kabala, Natalie Swinford, Maria J. Mason, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Ascertaining the risks and benefits of different behaviors is a central goal of research on territoriality. Although most territorial behavior is ritualized, with concomitant reduced risks for both residents and intruders, this ritualization is generally found to be underpinned by rare, highly consequential, interactions. The agonistic behavior of the intertidal owl limpet, Lottia gigantea, involves defense of a feeding territory, and includes a relatively explosive thrusting response by territory holders against intruding conspecifics. We here ask whether this thrusting behavior is capable of entirely dislodging intruders from their rocky wave-swept substratum, thereby ridding the resident of future challenges by …

Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Dekay’s Brownsnake (Storeria dekayi) generally occurs in southeastern parts of the state, where the species was known from 16 counties. Herein, we update the distribution of S. dekayi in the state and briefly comment on habitat and abundance from observations in September and October 2018. We documented 7 new county records that extend its distribution in south-central Nebraska. We observed that S. dekayi does not only reside in mesic wooded habitats in Nebraska but also occupies open environments, including areas with upland grasslands and row-crop agriculture. Dekay’s Brownsnake currently is listed as a species of concern …

Immune-Endocrine Links To Gregariousness In Wild House Mice, Patricia C. Lopes, Esther H. D. Carlitz, Morgan Kindel, Barbara König

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Social interactions are critically important for survival and impact overall-health, but also impose costs on animals, such as exposure to contagious agents. The immune system can play a critical role in modulating social behavior when animals are sick, as has been demonstrated within the context of “sickness behaviors.” Can immune molecules affect or be affected by social interactions even when animals are not sick, therefore serving a role in mediating pathogen exposure? We tested whether markers of immune function in both the blood and the brain are associated with gregariousness, quantified as number of animals interacted with per day. To …

Predicting Changes In Bee Assemblages Following State Transitions At North American Dryland Ecotones, Melanie R. Kazenel, Karen W. Wright, Julieta Bettinelli, Terry L. Griswold, Kenneth D. Whitney, Jennifer A. Rudgers

All PIRU Publications

Drylands worldwide are experiencing ecosystem state transitions: the expansion of some ecosystem types at the expense of others. Bees in drylands are particularly abundant and diverse, with potential for large compositional differences and seasonal turnover across ecotones. To better understand how future ecosystem state transitions may influence bees, we compared bee assemblages and their seasonality among sites at the Sevilleta National Wildlife Refuge (NM, USA) that represent three dryland ecosystem types (and two ecotones) of the southwestern U.S. (Plains grassland, Chihuahuan Desert grassland, and Chihuahuan Desert shrubland). Using passive traps, we caught bees during two-week intervals from March–October, 2002–2014. The …
