Kansas Agricultural Experiment Station Research Reports

Salmonella entericaserotype 4,[5],12:i:- (STM) has become an increasing problem for food safety and has been often detected in pork products. For this study, weanling pigs were exposed to STM-contaminated feed, water, or air to determine possible STM transmission routes. An uninoculated control group of pigs was included. The STM was monitored daily in feces and rectal and nasal swabs. The STM colonization was most prevalent in tissues from tonsil, lower intestine, and mesenteric lymph nodes. No differences in lesion severity were observed between inoculated and control pigs. Contaminated feed, water, and aerosolized particles caused infection in weaned pigs; however, …


Understanding Caribou Population Cycles, Jack R. St. John Jan 2022

Understanding Caribou Population Cycles, Jack R. St. John

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, …


A Comparison Of Chimpanzee Wound Rates Before And During Covid-19 Zoo Closures, Robin Elana Salak Jan 2022

A Comparison Of Chimpanzee Wound Rates Before And During Covid-19 Zoo Closures, Robin Elana Salak

All Master's Theses

Visitor effect studies have had inconsistent impacts on animals, due in part to the inability to control for all confounding variables such as time of day, seasonal weather patterns, and so forth. This study represents the first instance where chimpanzee (Pan troglodytes) wounding frequencies were investigated across extensive time periods in the presence and complete absence of visitors, thus eliminating many visitor-related variables. Additional variables were eliminated through the zoo selection process, based on institutional responses to a 29-question survey, providing a novel approach to the question of visitor effects. The aim of this study was to determine …

Hotline Number To Reach And Offer Agricultural Information To Plain Anabaptists During The Covid-19 Workplace Closures, Emily Shoop, Carly Becker, Nathan Glenn Briggs, Danielle Smarsh

Journal of Amish and Plain Anabaptist Studies

The Penn State Extension Animal Systems Team developed a toll-free hotline phone number to convey short educational messages to maintain contact and outreach to Pennsylvania’s animal producing Amish, Mennonite, and other plain Anabaptist populations. During the COVID-19 pandemic, Penn State Extension’s programming went largely online via webinars, online courses, and emails. This change in programming excluded a large sector of Pennsylvania farmers who do not use or have access to the internet and, as such, were liable to miss important best management practice reviews and timely updates in animal agriculture. The Animal Systems Hotline offered callers the choice to listen …


Coyote Management In San Francisco, Matthew Greer Dec 2021

Coyote Management In San Francisco, Matthew Greer

Master's Projects and Capstones

As cities in North America grow, coyotes have become progressively more important species in urban ecosystems. Moreover, as coyotes increasingly use these urban spaces, human-coyote conflicts have become more common, creating a need for new management strategies. This paper will explore how the city of San Francisco could create a new coyote management plan for its highly visible coyote population. San Francisco has had a persistent coyote population since the early 2000s (Todd, 2018). Currently, the coyote population is close to 100 individuals and is still growing (J. Young, Presidio Trust, pers. comm.). To explore this topic a literature review …


The Art Of Amphibian Conservation: Linking In-Situ And Ex-Situ Populations Of Endangered Species Through Genome Banking, Isabella Joann Burger Dec 2021

The Art Of Amphibian Conservation: Linking In-Situ And Ex-Situ Populations Of Endangered Species Through Genome Banking, Isabella Joann Burger

Theses and Dissertations

Limited breeding success in captive breeding programs has necessitated the development of assisted reproductive technologies (ART) to preserve and increase genetic variation and population numbers of both captive and wild amphibian groups. ART has been shown to be successful in numerous anuran species, and current studies focus on the application of ART in ex-situ populations. The focus of this project is to show that linking in-situ and ex-situ amphibian populations through sperm cryopreservation, genome banking, and in-vitro fertilization is possible, with the goal of increasing gene diversity throughout groups in order to produce self-sustaining, wild populations in the future. Specific …

Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett

Theses and Dissertations

Winter hair coat shedding ability in southern U.S. cattle production has previously been associated with differences in adjusted birth and weaning weights of calves from dams that shed by June or later (Gray et al., 2011; Cauble et al., 2019). This study was developed to research possible avenues of why these relationships exist with winter hair coat shedding ability. The primary objectives of the following experiments were to: 1) evaluate how mineral status relates to winter hair coat shedding ability, 2) evaluate how winter hair coat shedding ability relates to apparent digestibility of forage, 3) evaluate winter hair coat shedding …


Going Vegan Or Vegetarian: Motivations & Influences, Faunalytics, Jo Anderson, Marina Milyavskaya Dec 2021

Going Vegan Or Vegetarian: Motivations & Influences, Faunalytics, Jo Anderson, Marina Milyavskaya

Diet

After studying hundreds of U.S. and Canadian consumers during their transition to vegetarianism or veganism (collectively referred to as veg*nism), a new report from research organization Faunalytics found that 42% of people’s veg*n journeys were motivated by health, 20% by animal protection, and 18% by environmental concern. For animal advocates interested in helping new vegans and vegetarians maintain their change of lifestyle, study results suggest a focus on self-driven motivations (like personal values or moral identity) and experiences with animal advocacy.

Forest Disturbance And Occupancy Patterns Of Carnivores: Results Of A Large-Scale Field Study In Maine, Usa, Bryn E. Evans

Electronic Theses and Dissertations

Understanding trends in the abundance and distribution of carnivores is important at global, regional and local scales due to their ecological role, their aesthetic and economic value, and the numerous threats to their populations. Carnivores in Maine range from the American black bear (Ursus americanus), to numerous native mesocarnivore species, such as American marten (Martes americana), fisher (Pekania pennanti), coyote (Canis latrans), red fox (Vulpes vulpes), bobcat (Lynx rufus), Canada lynx (Lynx canadensis) and to two small weasel species (Mustela erminea and Neogale frenata). …


Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop Dec 2021

Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop

Student Scholar Symposium Abstracts and Posters

Throughout the evolution of the family Canidae, there is a continuous belief that canines have an exceptional olfactory system which allows them to have a heightened sense of smell. Because of this olfactory sophistication, canines have become prevalent as detection animals in the military, homeland security, law enforcement, forensics, and civilian applications. However, while the trait is highly regarded, the exact role of nasal morphology is understudied. We aim to investigate the influences of nasal cavity and internal structure morphology in odor detection. However, nasal structure is a sophisticated morphological target and requires innovative solutions to capture the key variables …


The State Of Animal- Assisted Interventions In France: Is The Iahaio Model Relevant?, Alice Mignot, Gérard Leboucher, Véronique Servais, Karelle De Luca Nov 2021

The State Of Animal- Assisted Interventions In France: Is The Iahaio Model Relevant?, Alice Mignot, Gérard Leboucher, Véronique Servais, Karelle De Luca

People and Animals: The International Journal of Research and Practice

Animal- assisted interventions (AAI) became more generalized in health care settings and their development in Europe is increasing. In France, the practice has grown in the absence of official recognition and regulation. In this context, we aim to identify the main characteristics of the French practice of AAI that can influence the establishment of a local regulation. Second, we aim to question the relevance of the model proposed by the International Association of Human- Animal Interaction Organizations (IAHAIO) distinguishing animal- assisted therapies (AAT) and (AAA) animal- assisted activities from the French practice of AAI. We interviewed 111 French handlers in …


Free-Ranging And Feral Cats, Alex Dutcher, Kyle Pias, Grant Sizemore, Stephen M. Vantassel Oct 2021

Free-Ranging And Feral Cats, Alex Dutcher, Kyle Pias, Grant Sizemore, Stephen M. Vantassel

Wildlife Damage Management Technical Series

Domestic cats (Felis catus) are a common household pet in the United States, with an estimated 25.4% of households owning cats (American Veterinary Medical Association 2018). While an increasing number of cat owners keep their pet cats exclusively indoors, a portion of society maintains that domestic cats are entitled to a free-ranging lifestyle and may even consider unowned domestic cats to be wildlife. Although wildlife managers recognize the beliefs of many concerned stakeholders, including advocates who use strong emotional appeals on behalf of cats, it remains that free-ranging and feral domestic cats are an invasive species spread by humans (Lowe …

Rapid Quantitative Analysis Of Toxic Norditerpenoid Alkaloids In Larkspur (Delphinium Spp.) By Flow Injection - Electrospray Ionization – Mass Spectrometry, Dale R. Gardner, Stephen T. Lee, Daniel Cook

Poisonous Plant Research (PPR)

A rapid flow injection - electrospray ionization – mass spectrometry (FI-ESI-MS) method for the quantitative and qualitative analysis of norditerpenoid alkaloids in larkspur plants was developed. The FI-ESI-MS method was calibrated for alkaloid concentrations with larkspur plant samples against an existing Fourier transform infrared spectroscopy FTIR method. There was a strong correlation (r = 0.9926, r = 0.9891) between the FTIR and FI-ESI-MS methods. The relative standard deviation (RSD) for all measurements were ≤ 6.2 % except for the sample with the lowest concentration which was 19%. The sample throughput of the FI-ESI-MS method is much higher than the FTIR …


Kentucky Equestrians: Defining Socioeconomic Contexts For Extension Programming, Kimberly I. Tumlin, Karin Pekarchik, Steven Claas Sep 2021

Kentucky Equestrians: Defining Socioeconomic Contexts For Extension Programming, Kimberly I. Tumlin, Karin Pekarchik, Steven Claas

The Journal of Extension

Understanding relationships between demographic and economic factors and equestrian participation could improve horse program design. We implemented an online survey that characterized associations of participation in equine activities, socioeconomic factors, and economic factors with age. Seventy-five percent of respondents ride, and 34% are recreational, non-competitive participants. Respondents were mostly female, and many participate in the sport throughout life. Many respondents indicated they overspent on equestrian activities. Horse programs should incorporate information and activities that address issues unique to females, should develop skills required by amateur or recreational riders, and should incorporate information on financial wellness.

Anything For A Cheerio: Brown Capuchins (Sapajus [Cebus] Apella) Consistently Coordinate In An Assurance Game For Unequal Payoffs, Lauren M. Robinson, Mayte Martínez, Kelly L. Leverett, Mattea S. Rossettie, Bart J. Wilson, Sarah F. Brosnan

ESI Publications

Unequal outcomes disrupt cooperation in some situations, but this has not been tested in the context of coordination in economic games. To explore this, we tested brown capuchins (Sapajus [Cebus] apella) on a manual version of the Stag Hunt (or Assurance) Game, in which individuals sequentially chose between two options, Stag or Hare, and were rewarded according to their choices and that of their partner. Typically, coordination on Stag results in an equal highest payout, whereas coordinating on Hare results in a guaranteed equal but lower payoff and uncoordinated play results in the lowest payoff when playing …

The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser

Electronic Theses and Dissertations

Arsenic is a toxic metalloid that exceeds safe drinking water standards in groundwater in many locations worldwide. Arsenic exposure in fish has been linked to destruction of gill tissues, impairment of growth, decreased muscle mass, memory impairment, increased aggression, and avoidance behaviors. We examined the behavior of mummichogs (Fundulus heteroclitus) following arsenic exposure during development in two studies. Embryos were collected from fish from three reference sites: Scorton Creek (SC), Massachusetts, Wells Harbor (WE), Maine, and Block Island (BLOC), Rhode Island and two contaminated sites: Callahan Mine (CM), Brooksville, Maine, and New Bedford Harbor (NBH), Massachusetts. Embryos were …

Intensive Hunting Pressure Changes Local Distribution Of Wild Boar, Jakub Drimaj, Jiří Kamler, Radim Plhal, Přemysl Janata, Zdeněk Adamec, Miloslav Homolka

Human–Wildlife Interactions

Wild boar (Sus scrofa) is now an important species of wild ungulates in Central Europe. Next to conflicts of wild boar with agriculture, the main threat of wild boar presence lies in the expansion of African swine fever across Europe. The regulation of the wild boar population is complicated by the high reproduction rate and intelligent behavior of the species, which limits hunting effectiveness. We analyzed the spatial behavior of wild boar in an environment with a lack of natural food resources. The study area consisted of a forest complex (1,283 ha) with 2 areas. In the “risk” …

Ikkuma: An Artistic Vr Storytelling Experience, Yangli Liu

Frameless

Ikkuma is an interactive storytelling experience utilizing Tilt Brush and Unity. It is about a land being swallowed by the sea, where conflict cracks ice and fire tears families apart. Ikkuma is the Inuvialuit word for fire, a central element to the work. The fundamental theme of Ikkuma is global warming and its impact on the Arctic ecosystem. The players must learn to tame the fire in their hearts and the Inuit traditional knowledge if they hope to survive the harsh yet fragile Arctic tundra.


Self-Injurious Behavior In A Captive, Malimprinted Coragyps Atratus, Brittany Swartout Jul 2021

Self-Injurious Behavior In A Captive, Malimprinted Coragyps Atratus, Brittany Swartout

The Pegasus Review: UCF Undergraduate Research Journal

Lurch is a Coragyps atratus who was raised in captivity and imprinted on humans. He was an education animal at the Silver Springs Zoo until its closure. Lurch was moved to the Central Florida Zoo and has been feather picking and self-mutilating since then. Self-injury is not well documented in raptors and few treatments have been explored. It is often caused by stress of some sort and is not seen in the wild. These observations were conducted in order to observe the environmental factors that influenced these behaviors in Lurch. In an attempt to curb his feather picking, Lurch was …

Publications and Research

Species often experience spatial environmental heterogeneity across their range, and populations may exhibit signatures of adaptation to local environmental characteristics. Other population genetic processes, such as migration and genetic drift, can impede the effects of local adaptation. Genetic drift in particular can have a pronounced effect on population genetic structure during large-scale geographic expansions, where a series of founder effects leads to decreases in genetic variation in the direction of the expansion. Here, we explore the genetic diversity of a desert lizard that occupies a wide range of environmental conditions and that has experienced post-glacial expansion northwards along two colonization …

A Behavioral Study Of Chacoan Peccaries (Catagonis Wagneri) In A Zoo Environment, Desdemona Kurowski

The Pegasus Review: UCF Undergraduate Research Journal

Found in the highly specialized area of the Gran Chaco, the Chacoan peccary (Catagonis wagneri) is an endangered animal threatened by industrial agriculture. In an attempt to save this species, three C. wagneri were brought to Central Florida Zoo where their health is monitored with great care in an attempt to possibly breed them in the future. While taking care of the other hooved animals, zookeepers are not able to give the peccaries their uninterrupted attention and have turned to help from the University of Central Florida to closely track if their behavior is indicative of a healthy, properly enriched …


Our Peer The Pigeon: Impacts Of The Covid-19 "Anthropause" On Psu Campus Urban Foragers, Audrey Douglass Jun 2021

Our Peer The Pigeon: Impacts Of The Covid-19 "Anthropause" On Psu Campus Urban Foragers, Audrey Douglass

University Honors Theses

The 2020 COVID Pandemic presented a paradigm shift dubbed, by some scholars, the 'Anthropause', an ecological epoch in which humans faded from the public sphere. As was the case for many urban species that depend on the foraging of food waste, this meant a fundamental disruption to their food systems and to the entire urban eco-web. The PSU Campus Park Blocks presents a unique opportunity to observe animal behavior, while also a succinct microcosm to study food waste flow changes, and compare species layout to other urban parks in the METRO area. Decreased food waste output from proximal …
