Living Among Wildlife: Elevating Human-Wildlife Interactions And Coexistence, Bridget Rebecca Murphy

Graduate Student Portfolios, Professional Papers, and Capstone Projects

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

Back To The Future: Achieving Resilient, Sustainable Grasslands Through Restoration Of Ecological Norms / Overview – The Problem, The Opportunity, Pat D. Keyser, C. Bitler

IGC Proceedings (1993-2023)

Grasslands are one of the largest biomes on earth, are the largest agricultural enterprise in the U.S., serve as a major carbon pool, produce high quality dietary proteins, and host a rich biodiversity. However, grasslands, including those of the eastern U.S., have been heavily altered and degraded reducing their resiliency and negatively impacting native fauna. Recent scientific advances in grassland establishment and management, along with the opportunity to monetize the carbon benefits of native grasslands, could provide the needed social and economic support to make such restoration possible on a large scale. Where restored grassland communities align with historical, ecological …

The Devil You Know And The Devil You Don’T: Current Status And Challenges Of Bovine Tuberculosis Eradication In The United States, Daniel J. O'Brien, Tyler C. Thacker, Liliana C.M. Salvador, Anthony G. Duffiney, Suelee Robbe‑Austerman, Mark S. Camacho, Jason E. Lombard, Mitchell V. Palmer

United States Department of Agriculture Wildlife Services: Staff Publications

Having entered into its second century, the eradication program for bovine tuberculosis (bTB, caused by Mycobacterium bovis) in the United States of America occupies a position both enviable and daunting. Excepting four counties in Michigan comprising only 6109 km2 (0.06% of US land area) classified as Modified Accredited, as of April 2022 the entire country was considered Accredited Free of bTB by the US Department of Agriculture for cattle and bison. On the surface, the now well-described circumstances of endemic bTB in Michigan, where white-tailed deer (Odocoileus virginianus) serve as a free-ranging wildlife maintenance host, may appear to be …

Generation Z’S Perceptions Of Hunting And Conservation Efforts In Arkansas, Hannah Ferguson

Graduate Theses and Dissertations

Hunting participation numbers have steadily declined since the 1980s and Generation Z is not engaging in hunting. Hunting is one of the most effective tools for managing wildlife populations and ensuring the success and local ecosystem conservation. Many wildlife stewardship institutions, such as Arkansas Game and Fish Commission in Arkansas, are funded by sales taxes imposed on firearms, ammo, and archery equipment. With a decline in hunting participation, it is imperative state-run wildlife stewardship organizations and other hunting institutions learn the best practices for communicating with younger generations. This study sought to understand Generation Z’s perceptions of hunting and conservation …

Density And Nest Success Of Shrub-Dependent Birds On Formerly Strip-Mined Lands, Luke Headings

Electronic Theses & Dissertations

As bird populations continue to decline across North America, it is important to understand the benefits that disturbed habitats can have for breeding birds. One of the major land disturbances and causes of habitat loss in the United States is surface mining, which often results in altered vegetative communities. The primary goal of this study was to evaluate the relationships between bird populations, habitat, previous and current land use, and densities of invasive plant species on formerly strip-mined land. Due to the proliferation of invasive shrub species in post-mined landscapes, we sought to determine the effects of post-mined habitat features …

Exploring A Potential Bias In Detection Of Mesopredators By Cameras, Rylee Gibson

Biological Sciences Undergraduate Honors Theses

Mesopredators, such as the raccoon (Procyon locor), Virginia opossum (Didpelphis virginiana), and striped skunk (Mephitis mephitis) play crucial ecological roles as predators, prey, and disease vectors across much of the United States. Because of their importance and the way that populations of these mesopredators can dramatically increase due to human-subsidized resources, it is imperative that studies attempting to quantify mesopredator community composition are accurate and unbiased. However, it has recently been suggested that not all mammals trigger motion-activated wildlife game cameras at the same rate and for some species detection probability may be biased. My goals for this thesis were …

High-Risk Wildlife Strike Regions: An In-Depth Visual Representation Of Wildlife Strikes At And Around Part 139 Airports In Florida., Luke P. Ochs, Flavio A. C. Mendonca Ph.D.

Beyond: Undergraduate Research Journal

Wildlife strikes with aircraft have been and continue to be a problem in the aviation industry costing millions of dollars in both damage and delays. This study used the geoprocessing information system ArcGIS to depict wildlife strikes at Florida’s 26 Part 139 Airports from 2012 to 2021. Importing reports from the National Wildlife Strike Database into ArcGIS, this study used symbology and geoprocessing tools to create a color/ size gradient that depicts the risk (number of damaging strikes out of known strikes) at each airport. Using an interactive map with ArcGIS Online viewers can observe then select each airports vector …

Challenges And Opportunities For Sustainable Rangeland Pastoral Systems In The Edwards Plateau Of Texas, J. W. Walker, J. L. Johnson, C. A. Taylor Jr.

IGC Proceedings (1993-2023)

This paper focuses on pastoral systems in an area of west-central Texas known as the Edwards Plateau. These rangelands have a combination of grass, forb and browse species and are used primarily for combinations of grazing by cattle, sheep, goats and wildlife. A major ecological challenge is woody plant encroachment. Stocking rate is the major factor affecting sustainability and historically this area was heavily grazed. Today the stocking rate is half or less of its historical peak. Species of livestock has shifted from predominantly small ruminant to cattle. About 70 % of pastoralists use some sort of rotational grazing system. …

The Links To Cancer: How Golf Became Dangerous And What We Can Do To Save The Game, Meredith Boos

Undergraduate Theses, Professional Papers, and Capstone Artifacts

This study is a comprehensive meta-analysis on health claims linked to exposure to golf courses, more specifically the chemicals used to maintain their appearance. It provides a brief history of the golf industry and how its growth exacerbated the environmental impact as well as an explanation of the legal landscape that will affect golf course management. Golf courses can disrupt local ecologies, contaminate ground water, rivers, lakes and streams with run-off, and be responsible for the bioaccumulation of chemicals which remain dangerous for decades. Despite the adverse effects of golf courses on the environment, there remains an opportunity to transform …

"Our Loons": Participant Attachments And Motivations Within A Community-Based Monitoring Program, Taylor Tewksbury

Graduate Student Theses, Dissertations, & Professional Papers

Organizations can benefit from understanding person-place relationships and volunteer motivations as they recruit and sustain involvement in their community-based monitoring (CBM) programs. Place attachment, or the bond between people and their meaningful environments, is one lens through which to explore these relationships. Past studies have associated place attachment with environmentally responsible behaviors (ERB), such as CBM involvement. However, few studies have explored the relationship between place attachment and CBM in the context of volunteers’ attachment to the species of study.

The purpose of this research study was to explore the place-based relationships and motivations among volunteers of the Loon Preservation …

Further Investigation Of Lead Exposure As A Potential Threatening Process For A Scavenging Marsupial Species, D. J. Hutchinson, E. M. Jones, J. M. Pay, J. R. Clarke, Michael T. Lohr, J. O. Hampton

Research outputs 2022 to 2026

There is a growing recognition of the harmful effects of lead exposure on avian and mammalian scavengers. This can lead to both lethal and non-lethal effects which may negatively impact wildlife populations. Our objective was to assess medium-term lead exposure in wild Tasmanian devils (Sarcophilus harrisii). Frozen liver samples (n = 41), opportunistically collected in 2017–2022, were analysed using inductively coupled plasma mass spectrometry (ICP-MS) to determine liver lead concentrations. These results were then used to calculate the proportion of animals with elevated lead levels ( > 5 mg/kg dry weight) and examine the role of explanatory variables that may have …
