Encoding Of Emotional Valence In Wild Boar (Sus Scrofa) Calls, Anne-Laure Maigrot, Edna Hillmann, Elodie Briefer

Bioacoustics Collection

Measuring emotions in nonhuman mammals is challenging. As animals are not able to verbally report how they feel, we need to find reliable indicators to assess their emotional state. Emotions can be described using two key dimensions: valence (negative or positive) and arousal (bodily activation or excitation). In this study, we investigated vocal expression of emotional valence in wild boars (Sus scrofa). The animals were observed in three naturally occurring situations: anticipation of a food reward (positive), affiliative interactions (positive), and agonistic interactions (negative). Body movement was used as an indicator of emotional arousal to control for the effect of …

Resource Selection Of Free-Ranging Horses Influenced By Fire In Northern Canada, Sonja E. R. Leverkus, Samuel D. Fuhlendorf, Marten Geertsema, Brady W. Allred, Mark Gregory, Alexandre R. Bevington, David M. Engle, J. Derek Scasta

Human–Wildlife Interactions

Free-ranging or feral horses (Equus ferus caballus) were important to the livelihood of First Nations and indigenous communities in Canada. The early inhabitants of the boreal region of British Columbia (BC) capitalized on naturally occurring wildfires and anthropogenic burning to provide forage for free-ranging horses and manage habitat for wildlife. This form of pyric herbivory, or grazing driven by fi re via the attraction to the palatable vegetation in recently burned areas, is an evolutionary disturbance process that occurs globally. However, its application to manage forage availability for free-ranging horses has not been studied in northern Canada. Across Canada, there …

The Horse: A Driving Force For The Lifestyle Of Grooms, Nicole Foright

Online Theses and Dissertations

The fundamental components of co-occupational relationships between humans and animals and their impact on occupational identity is an area for exploration in the study of occupation. Evaluating the lives of persons whose daily occupations involve working with animals contributes to the exploration of human-animal co-occupations. The aim of this research was to understand the lifestyle of International 4-in-Hand Combined Driving grooms and their symbiotic relationship with horses. This qualitative descriptive study used three methods for data collection and triangulation: semi-structured interviews, observation, and photographs, from 4 participants who served as gatekeepers understanding the culture surrounding the driving community. The data …

The Professional Association of Therapeutic Horsemanship International (PATH Intl.) is an organization that offers therapeutic horseback riding (THR) and other equine-assisted activities and therapies in the United States. Research on how horses are used and cared for in PATH Intl.-affiliated THR programs is limited. Therefore, the objective of this study was to gather data regarding horse use and care to form a baseline. A survey developed via SurveyMonkey® and distributed through Google Mail Merge to 659 PATH Intl.-affiliated programs in September 2017. A total of 270 responses were received; 264 were eligible for data analysis. Descriptive statistics were used to …

Effects Of Essential Oils And Amino Acid Profile On The Growth And Health Of Receiving Cattle, Kelsey Machens

Murray State Theses and Dissertations

The objective of this trial was to evaluate the effects of amino acid profile and essential oil products on receiving calf growth and feed efficiency, as well as evaluate the effects of amino acid profile and essential oil products on fecal and blood Immunoglobulin A (IgA) concentrations as a marker for systemic and gastrointestinal tract immune status of receiving calves. One hundred-thirty crossbred calves (500-600 lbs) were transported to the ADM Animal Nutrition Research Facility in Mendon, IL. On d -1, cattle were weighed, dewormed, implanted, vaccinated, and a rectal temperature was recorded. An at-risk group of cattle was targeted …

Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan A. Lichtenwalter, Jason K. Apple, Beth Kegley, Tsung C. Tsai

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Overall, no effect of teat order was found on average daily gain, average daily feed intake, gain-to-feed ratio, or body weight among pigs from each section …

Muskrats, James E. Miller

Wildlife Damage Management Technical Series

The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.

Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.

Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation …

Wild Turkeys, James E. Miller

Wildlife Damage Management Technical Series

Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys (Figure 1) are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and …

Life In The Dirt: Factors Influencing The Behavior And Distribution Of Spea Intermontana In Eastern Washington State, Corey Brumbaugh

All Master's Theses

I divided my thesis into two major studies focusing on the Great Basin Spadefoot Toad, Spea intermontana, at the Beverley Dunes (Beverley, WA). The first study explored the effects of temperature and water level on the rate of metamorphosis. We gathered data on rates of development, survival, body mass, snout-vent length, and hind leg length of metamorphs under 4 treatments: 20C x High Water, 30C x High Water, 20C x Water Loss, and 30C x Water Loss. These data show that temperature has a stronger effect on the overall rate of metamorphosis of Great Basin Spadefoot Toads. The second …

A Correlation Study Of The Nest Incubation Period And Hatchling Development And Success Rate For Olive Ridley Sea Turtles (Lepidocheyls Olivacea) Turtle Conservation: Playa Junquillal, Costa Rica, Natalie O'Brien

Williams Honors College, Honors Research Projects

Listed as vulnerable by the International Union for the Conservation of Nature (IUCN) the Olive Ridley sea turtle contributes to the stability of an ecosystem by transferring nutrients and energy to both the terrestrial and oceanic environment [1]. Costa Rica holds some of the most prominent nesting beaches for Olive Ridley sea turtles in the World. Collection and relocation of surveyed nests to monitored hatcheries increases the success rate significantly [2]. Realistically, nest and hatchling protection against land-based threats such as poaching, predation and beach erosion is a practical and accessible conservation measure. Facilitated by access to the sea turtle …

An Historical Overview And Update Of Wolf-Moose Interactions In Northeastern Minnesota, L. David Mech, John Fieberg, Shannon M. Barber-Meyer

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wolf (Canis lupus) and moose (Alces americanus) populations in northeastern Minnesota, USA, have fluctuated for decades and, based on helicopter counts, moose numbers declined to a new low from 2006 to about 2012. Other steep declines were found in 1991 and 1998 during periods when moose counts were done with fixed-wing aircraft; these declines also appeared to be real. Winter wolf numbers, monitored in part of the moose range, had been increasing since about 2002 to the highest population in decades in 2009. However, from 2009 to 2016, wolves decreased precipitously, and the moose- population decline leveled …

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott

Human–Wildlife Interactions

Management of wild horse (Equus ferus caballus ) populations on western U.S. rangelands has been a challenge since horses were given legal protection through the passage of the Wild Free-Roaming Horses and Burros Act (WFRHBA) in 1971. Horses have no eff ective predators, and unmanaged populations can double in 4–5 years and triple in 6–8 years. In order to meet the multiple-use paradigm for managing public rangelands, the Bureau of Land Management (BLM) has limited horse population growth through the periodic capture and removal of animals. While the WFRHBA mandates disposal of captured horses through placement into private ownership and …

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez

Human–Wildlife Interactions

Porcine zona pellucida (PZP) immunocontraception was developed to provide a more humane, effective, and inexpensive method of population regulation for wildlife species. It has been used to regulate populations of several species including white tailed deer (Odocoileus virginianus), elk (Cervus elaphus ), black bear (Ursus americanus ), and the feral horse (Equus ferus caballus) with varying levels of success. Early studies on Assateague Island National Seashore, Maryland, USA, suggested PZP was as an ideal form of fertility control because it reduced the likelihood of conception to

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …
